Jack

Jack is a Transmit Demon who was part of the Heaven Crystal Recovery Team.

Background
Jack was born as a Transmit Demon, a race of demons that possess the unique ability "Telepathy Link". At one point in his life, he fell in love with another Transmit Demon named "Rose". However, the two of them belong to feuding families, and their respective family's elders despise each other over what Jack called "a small grudge", and strongly opposed their relationship. Jack joined the Heaven Crystal Recovery Team despite having no combat abilities after Yan Sis promised him that she will force the elders to make an exception and allow him and Rose to be together if the mission is successful.

Personality
Jack is really honest, as shown when he kept his promise of not ratting Public Relations Specialist and Champion out to Yan Sis, even though he easily could have. This trait was exploited by the two and was used to threaten his and Rose's lives.

Jack is also righteous, as shown when he threatened to tattle on Public Relations Specialist and Champion for not helping the other members of the Heaven Crystal Recovery Team and only caring about their own pleasure.

Jack is extremely heterosexual and strongly opposes anything that is even slightly homosexual, as shown when he refused, but was forced to kiss Che Yongtai to allow him to leave the Limbo Stone dimension by Ye Yan. This personality trait was later used by Ye Yan to determine the fake Jack when Shi Ji transformed into him to avoid being caught.

Appearance
Jack is a short, orange and egg-like demon with short, but extendable limbs and two horns on his head. He is always seen wearing a loincloth. His appearance strongly resembles an egg, hence the nickname he is called by the Department of Night.

Abilities and Powers
Jack is born as a Transmit Demon, so he naturally possesses the ability "Telepathy Link", as well as the ability to elongate his limbs. Despite the supernatural techniques, he is described as having no combat capabilities at all by many people, including himself.

Transmit Demon exclusive techniques

 * Limb Elongation: Transmit Demons are able to elongate their limbs. Jack has been seen using this technique to grow taller and see further, and extending his arm.
 * Telepathy Link (精神链接): Transmit Demons are able to establish a telepathic line of communication with someone else and communicate with them telepathically. This technique bypasses dimensional obstruction, making it far more advanced than most other telepathy techniques. The line of communication can only be held for five days, after five days it will automatically disable.

Trivia
Jack and his lover's name, Rose, are references to the names of the main characters in the romance disaster film "Titanic". Their backstories are also references to the story between Romeo and Juliet from the famous play by William Shakespeare, "Romeo and Juliet".
