Huang Xiaoyan

Huang Xiaoyan is a student from Xiahou High School who lives a double life as an Untitled Sage guardian and protects normal humans from monsters. Due to her actions and relevance in the series, Huang Xiaoyan can be considered the main protagonist.

Background
Huang Xiaoyan is a prodigious Untitled Sage born to an Untitled Sage mother from the main branch sanctum of the Hollow Jade Mountain. Due to being a female, she was kept in the sanctum and trained to become an Untitled Sage since she was young. Before she was 15 years old, she was able to open her Heaven's Eye with almost no side effects at all, achieve the rare ability "Calm Sage Mentality" that could only be achieved by a few prodigies throughout history, master Tai Chi and acquire the Universal Miracle Gourd. After she turned 15, she was selected as the representative Untitled Sage guardian and eventually arrived at Bozhou to join the Department of Night.

Personality
Because of the Untitled Sage training she went through, Huang Xiaoyan is often characterised as being cold and oblivious towards concepts such as love or romance, as shown when she either rejects or ignores many men that show interest in her, such as Che Yongtai and Yue Wuer. However, it is revealed she has romantic feelings for Ye Yan as proven by multiple people, but usually she quickly denies such statements.

Due to living in the secluded Hollow Jade Mountain for almost her entire life, she never understood how to live in the modern world, which is why she relies on Ye Yan for financial support, housing and food. However in recent chapters, she has learned how to earn money and has slowly adapted to the modern world. This is also the reason why she occasionally speaks in an archaic dialect of Chinese instead of the modern dialect.

She also possesses a strong sense of justice and righteousness, as she swore she will never work along with Che Yongtai and Xi Sha, who are demons, and that she will never help gangsters or join a gang. Despite her aggressive attitude towards most demons and monsters, Huang Xiaoyan secretly wishes for a world where humans and monsters live in harmony, as shown by Xumi Luo's "Dream Come True" drug.

During combat, Huang Xiaoyan's actions clearly contrast that of Ye Yan's. Instead of planning strategies carefully, she recklessly attacks the enemy with all her moves and defends only when necessary, this allows her to easily overpower an enemy but causes her to disregard the surrounding environment.

Appearance
Huang Xiaoyan has long, straight black hair that sports an ahoge, red eyes and a tattoo on her right outer thigh. The combination of having fair skin, a voluptuous figure and a beautiful face earned her the title "Goddess" among the male students in Class 1-A.

Her Untitled Sage attire consists of a white daoist robe with blue flower and cloud-like patterns tied together with a ribbon at her abdomen and a red undershirt underneath. She always wears her green Gourd Child on her hair. While in school, she wears the female student school uniform without the blazer, consisting of white shirt with a blue tie and skirt. At home, she only wears her red undershirt. During the Double Devils Arc, she wore a white bikini and a white dress. During the Dong Guan Arc, she wore a black suit, skirt and tie. During the School Play Arc, she dressed up as Snow White, Cinderella and eventually Tang Seng from Journey to the West. During the Lovers Party Arc, she wore a white halter dress and a white nightgown. During the Ancient Tree of Time Arc, she was reverted back to a child due to Yun Zhonghe's drugs. During the Sage Hunter Arc, she wore a maid costume and a pair of fake cat ears.

Abilities and Powers
Being a main branch Untitled Sage and having trained since she was young, Huang Xiaoyan is physically strong to a nearly monstrous level, capable of easily beating Ye Yan in a fist fight, fight against Hong Hong, a Tai Chi master on equal grounds using martial arts alone and beat Luo Xiaobao, a Sage Hunter who is the natural enemy of Untitled Sages using only one of her hands. Such strength combined with her prodigious talent and weapons makes her a force to be reckoned with.

Weapons

 * Universal Miracle Gourd (乾坤奥妙大葫芦): A weapon exclusive to Huang Xiaoyan. By channeling the green Gourd Child she wears on her head, Huang Xiaoyan can summon the Universal Miracle Gourd. The Universal Miracle Gourd is a treasured magical weapon that belonged to the Qing Palace on top of the Tiantai Mountain. It was created from a gourd that grew from a spiritual vine and was refined by Dongfang Taiyue 800 years ago. If Huang Xiaoyan calls a person's name and that person answers, they will be sucked into the gourd and will dissolve into blood in 1 hour and 45 minutes due to the acidic environment inside the gourd. If Huang Xiaoyan releases the person from the gourd, she can still suck them back in without calling their name within 45 minutes. Untitled Sages can escape from the gourd using Substitution tags. By using this weapon in conjunction with her Thousand Ri Shout, the range of effectiveness can be increased. It can also be used as a melee weapon during a Sage Duel.
 * Sword: A sword with a black handle used by Huang Xiaoyan, who uses it to slay monsters and demons. It is extremely durable, as it did not break while being bitten by Xi Sha. By channeling energy into the sword, she can also create air slashes by swinging it.
 * Spell tags (灵符): Spell tags are yellow pieces of paper with different inscriptions written on them using cinnabar that represent the type of spell tag it is. By spiritually bonding with the tag, Huang Xiaoyan can use it or multiply it to greater amounts and store them inside her Sage Mind for later use. After summoning them, Huang Xiaoyan can control the direction they fly towards and induce their effects.

Untitled Sage exclusive techniques

 * Sage Mind (仙识之海): The Sage Mind is an innate attribute present in Untitled Sages and their descendants. The Sage Mind is the origin of the Untitled Sages' magical energy and can be used to store hundreds, thousands or even millions of different types of spell tags within in, which can then be summoned around the Untitled Sage to use in battle. Since the Sage Mind is linked to the consciousness of an Untitled Sage, Sage Hunters can invade the Sage Mind and read an Untitled Sage's focal memories and create illusions that target a weak point in the Untitled Sage's consciousness, causing them to either faint or die from shock.
 * Calm Sage Mentality (明净不动仙心): A technique acquired by very few prodigious Untitled Sages throughout history. When visibly activated, the Untitled Sage hovers above the ground a glowing yin-yang symbol below them. While active, this ability automatically detects the trajectories of incoming spell tags. It is also able to accurately detect the locations of spell tags manifested near the user through Void Seal Creation. By coupling this technique with a tremendous amount of Erase Tags, the user could render themselves immune to any spell tag attacks by intercepting and nullifying them. Users of this technique are also immune to having their Sage Minds invaded by Sage Hunters, preventing them from having their thoughts and memories read or being mind controlled. While Sage Hunters can pollute their Sage Mind with their darkness, it would only cause a headache in the affected Untitled Sage. Only when they touch the black blood of the Sage Hunter would this technique be cancelled and render them vulnerable. This move requires the user to be completely tranquil for it to visibly activate, or it would also slowly weaken and eventually deactivate if the user is influenced by strong emotions, such as embarrassment.
 * Heaven's Eye (天眼): A powerful ability used by some Untitled Sages and their descendants. When the Heaven's Eye is opened, Untitled Sages are able to see things invisible to the naked eye, see through obstructions, see the cause and effect of events, draw the power of the heavens into themselves and use it as their own. Untitled Sages that opened their Heaven's Eye for the first time will experience some kind of drawback, and the effects of the drawback either increases or stays the same every time they open it again. For Huang Xiaoyan, every time she opens her Heaven's Eye her eyesight and perception temporarily weakens. She has been seen using her Heaven's Eye to predict the future, track a monster down with his blood and defeat multiple monsters by drawing in power.
 * Sage Duel Barrier (仙家对决结界): A barrier technique exclusive to Untitled Sages. When two Untitled Sages decide to duel to settle a conflict, they create a barrier to prevent others from interfering with their battle and fight each other using their respective gourds as melee weapons inside the barrier.
 * Blood Command Tag: Five Thunder Heaven Execution (真元血符: 五雷天心正法): An powerful attack used by main branch Untitled Sages. The user uses their own blood to create a giant Command Tag, which creates a cataclysmic thunderstorm. While preparing for this spell, the user must be extremely focused or else the power needed for this technique would backfire onto themselves, causing them to spit out blood and even die. If the spell is successfully cast, a giant bolt of lightning will strike the enemy, completely eviscerating them. If the preparation is halted before the lightning strikes, the lightning will lose its coordination and strike a random location.
 * Sage Sanctum Teleportation (仙门传送): An technique used by Untitled Sages that can be taught to others. This technique allows people to teleport to a designated Sage Sanctum through the use of a spell and a painting painted by an Untitled Sage belonging to that Sanctum. The painting can be on paper or on environmental substances. By reciting an incantation and activating the spell on their hand, the user can then either physically touch the painting with their palm or perform said motion at the painting and be teleported to the sanctum. All users of this spell have their own unique incantation for it, and depending on the incantation, one will be teleported to the specific entrance in the Sage Sanctum for the incantation's original user.
 * Lightning Shield (避雷诀): An exclusive technique used and bestowed by Moyun that can protect an Untitled Sage from the Heavenly Lightning Fire Field outside the Sage Prison.
 * Changing Spell (易装术): An exclusive technique for Untitled Sages and their descendants who can use it to quickly change their clothes. By recording a single set of clothing and storing it in their Sage Mind, the spell allows them to change their current clothes into the stored clothes when used, or repair their clothes if they are wearing the same set. Unless the Untitled Sage is talented and specializes in clothing changing, this spell does not allow one to change between several different clothes
 * Resting Spell (安息咒): An exclusive technique for Untitled Sages. When encountering an Untitled Sage who is on the brink of death, any Untitled Sage nearby must use the Resting Spell to read their memories and resolve any emotional entanglements they had during their lives so they can rest in peace.
 * Purification Spell (清净咒): An exclusive technique for Untitled Sages. It is used to purify zombies by ridding them of their internal zombie gas, returning them to a corpse.
 * Telepathy(心灵传音): Untitled Sages are able to telepathically communicate with each other. However, both users must use this spell at the same time for communication to be established.
 * Flight (御空飞行): Untitled Sages possessing incredible power are capable of hovering and flying in the air, though the speed that they can fly at varies. Huang Xiaoyan noted that she could perform this technique while under the effects of a Golden Scale Seal, though she speculated that her flying speed was slower than a car on an urban street.
 * God's Descent (仙君降临): The ultimate technique and form achievable by an Untitled Sage. With enough power, an Untitled Sage can summon the spirit of an extremely powerful Untitled Sage that once existed to possess themselves, granting them the abilities of the deceased Untitled Sage. While possessed, the Untitled Sage's eyes glow, and her body shines brightly with golden light and adapts the clothing of the channeled Untitled Sage.
 * Deity of Wondrous Way Possession (妙道天君附体): When activating God's Descent, an Untitled Sage can choose to be possessed by the Deity of Wondrous Way. While possessed, the Untitled Sage will gain a flowing sash that is draped around her shoulders, as well as the ability to cast various powerful magical spells.
 * Wondrous Way Rejuvenation (妙道回春诀): By covering a wound with a golden fluid, an Untitled Sage can rapidly heal injuries. However, the regeneration can be slowed by insufficient power and the environment, as shown when the golden fluid began to dissipate when Huang Xiaoyan tried to heal Ye Yan's injuries in the Underworld.
 * Destruction Spell (灭字诀): After manifesting golden energy around their hands, an Untitled Sage can fire the energy as destructive missiles to damage enemies.
 * Shrinking Ability: An Untitled Sage can shrink a person down to a tiny size and telekinetically control them to fly in their ear. While being shrunk, the person is enveloped in golden energy.
 * Spirit Water Cage (水灵笼): After manifesting a large pool of water beneath their enemy, an Untitled Sage then manipulates the water to trap them within a sphere of water.
 * Ancient Ice Prison (玄冰牢): An Untitled Sage exhales a cloud of freezing mist, which is cold enough to freeze water. It is used in conjunction with Spirit Water Cage after an enemy is trapped to reinforce the cage.
 * Clone Technique (分身术): An Untitled Sage can create physical duplicates of themselves to aid them. These clones appear identical to the Untitled Sage, and are also able to cast spells they possess. When destroyed, the clones crumble into stone.
 * Meteorite Fall (陨星落): An Untitled Sage manifests a giant ball of ice above them before throwing it down on an enemy, intending to crush them with it.
 * Heavenly Protection Spell (天罡护体诀): A spell that is intended to protect an Untitled Sage from external damage. However, it cannot protect the user against internal damage.
 * Teleportation Spell (瞬身诀): An Untitled Sage can instantly teleport to a nearby location to evade attacks after forming a hand sign. However, this spell cannot be used consecutively, which leaves them vulnerable to an attack immediately following their teleportation.
 * Heavenly Burst (天罡爆): An Untitled Sage manifests a ball of golden energy in front of their hand, which proceeds to fire countless rays of destructive light out from itself in all directions.
 * Wondrous Way Infinite Clone Technique (妙道无尽分身术): An Untitled Sage can dissipate themselves into countless tiny physical duplicates, which are small enough to resemble light particles. Their physical strength and spiritual power can be freely distributed among the clones or concentrated on a single clone. By surrounding an enemy with these clones, the Untitled Sage can attack any part of their body without risking being damaged. However, if a majority of the clones are damaged at once, the spell will be cancelled and the Untitled Sage will revert to their original body.
 * Wondrous Way Erudite Spell (妙道奇思诀): A spell similar to Intellect Enhance, which vastly augments an Untitled Sage's intelligence upon usage.
 * Deity of Cosmic Law Possession (万法天君附体): When activating God's Descent, an Untitled Sage can choose to be possessed by the Deity of Cosmic Law. While possessed, the Untitled Sage will emit an electrical aura, as well as the ability to cast various powerful magical spells. Notably, the Deity of Cosmic Law only possesses offensive techniques.
 * Destruction Tag Formation (灭字符阵): The Untitled Sage is able to control and summon multiple Destruction tags behind her in the formation of a fan.
 * Deity of Wish Fulfilment Possession (如意天君附体): When activating God's Descent, an Untitled Sage can choose to be possessed by the Deity of Wish Fulfilment. While possessed, the Untitled Sage will obtain a large Ruyi scepter and a tall Taoist headwear, and gain the ability to cast various powerful magical spells.
 * Stunning Wind Spell (定风咒): The Untitled Sage wields the scepter to cast this spell. It is unknown what this ability's effects are.
 * Sage Trinity (三圣合一): By borrowing the power of the cosmos, three Untitled Sages possessed by the Deity of Cosmic Law, the Deity of Wondrous Way and the Deity of Wish Fulfilment can combine their powers to access even more powerful abilities. While combining, they hover in the air with their backs to each other's as radiant light surrounds them. Upon combining their powers, they transform into a golden apparition of the right half of a giant woman's torso. The woman has short hair that spikes upwards, no mouth, and three arms. She is donned with a sleeveless shirt, bracelets on her three wrists with the lowest one having beads, and long curving accessories on her back.
 * Demon Vanquishing Spell (伏魔咒): After using Sage Trinity to combine the powers all three Untitled Sages, the giant apparition concentrates power into its lowest hand's index and middle finger before thrusting it down on the enemy. Known as the Primordial Annihilation Smite (原初毁灭天罚), the attack is capable of severely injuring a powerful ancient demon such as Y'Shari before pulverizing them into dust.

Huang Xiaoyan's techniques

 * Astrology Prediction Formation (化神占星阵): Huang Xiaoyan creates an eight trigram on the ground, stands in the middle of it and uses it to predict the future using astrology.
 * Million Seal Formation (百万灵符阵): Huang Xiaoyan summons millions of Explosive tags or Command tags around her and then bombards the enemy by launching the talismans at them.
 * Thousand Ri Shout (千里传音): Huang Xiaoyan sucks up a bunch of air and shouts, which is capable of reaching long distances. This move can be used in conjunction with the Universal Miracle Gourd to increase its effectiveness.
 * Mountain Slicing Slash (独劈华山): An unknown technique Huang Xiaoyan used to fight people offscreen.
 * Nine Swords of Dugu (独孤九剑): An unknown technique Huang Xiaoyan used to fight people offscreen, it's a reference to Dugu Qiubai's signature move, a character written by the Chinese wuxia novelist Jin Yong.
 * Tai Chi Cloud Hands (太极云手): A Tai Chi technique that allows Huang Xiaoyan to redirect a straight forward attack elsewhere. An extremely useful move, but it causes strain to her hands if the attack was very strong.
 * Million Seal Giant Binding Formation (万符锁妖大阵): Huang Xiaoyan summons millions of stunning tags and uses them to restrict the movements of a giant creature. However, with enough force, one can tear off the tags and free themselves.
 * Pencil Divination Technique (笔仙占卜之术): A move that requires two people to use, which Ye Yan used with Huang Xiaoyan. By putting a pencil between the hands of two people who are forming a specifc hand sign and pressing their thumbs onto the pencil, the pencil will automatically start to write a divination.
 * Innate Style Tai Chi (先天太极): A style of Tai Chi that Huang Xiaoyan learned while training as an Untitled Sage.

 * Dome of Heaven (天罡符阵): Huang Xiaoyan summons a bunch of spell tags and uses them to construct a dome above her. This dome is strong enough to withstand multiple Destruction tags. However, people can get around this defense by burrowing underground and emerging from inside.

 * Lunar Slash (圆月斩): Huang Xiaoyan uses her sword and performs a vertical circular slash around her that is capable of cutting of a motorcycle handle.
 * Golden Scale Seal (金鳞绝咒): As a result of Ye Yan's second time-travel experience, Huang Yuanqing, Huang Xiaoyan's ancestor, voluntarily sacrificed her ideal future to fix the timeline, which resulted in benefits from the Sage Sanctum for her descendants. Since Huang Xiaoyan would be living in the world after Ye Yan's time-travel, several powerful Untitled Sages before her placed a simplified Golden Scale Seal containing incredible power, words from former Untitled Sages, and a medicine that could instantly revitalize her within her Sage Mind upon her birth that would be removed once Ye Yan completes his time-travel, though it could only be used once.
 * Spell Reflection (法术反制): A technique acquired by Huang Xiaoyan after the Golden Scale Seal in her Sage Mind was activated. After experiencing an attack, Huang Xiaoyan would become immune to the effects of the same attack within the next twelve hours, and could even reflect the attack back to the assailant. This technique can even reflect status effects, such as the hallucinating effects of Dream Come True.
 * Intellect Enhance (智力强化): A technique acquired by Huang Xiaoyan after the Golden Scale Seal in her Sage Mind was activated. By concentrating energy into her brain, Huang Xiaoyan can greatly enhance her intelligence to formulate multiple strategies within a short amount of time.

Weaknesses
According to Ye Yan, who constantly brawls with Huang Xiaoyan on a daily basis, Huang Xiaoyan can only use her monstrous strength while standing, and it is possible to subdue her by pinning her wrists onto the ground, disabling her from using much of her strength.
