Background / History

Zhang Chen began as a living human who acquired the Gluttonous Ghost Main Soul through a black bead near his heart. Rather than fearing his condition, he became excited by the prospect of growing stronger through devouring ghosts. His early abilities included Telekinesis and Nail Growth, and his compatibility with the Main Soul rose after defeating ghostly creatures. 9 19

Over the following half-year, he improved academically, exercised regularly, explored his supernatural abilities, and became closer to Wang Yizhi. His family opened a successful mahjong parlor, while Zhang Chen increasingly took responsibility for both his household and his friends. 10

He became an unusual Jailer because he entered the system while still alive rather than being selected after death. As a Level 3 Jailer, he developed Ghost Devourer, Water Body, Flesh and Blood regeneration, Origin Power, and later Bone Armor. 79 96 182

During a time-travel passage, Zhang Chen reached Dujiang City in 1834. He assumed the identity of silk merchant Zhao You Shi, freed the concubine Li Qing, and chose to intervene in the Zhao household's internal conflict. 297

Zhang Chen's power and identity changed dramatically through repeated encounters with Kou Dan, the Clown, the Ghoul Realm, Faceless, and the Zero Realm. He eventually became Shen Hou's disciple, an Apostle, and a figure capable of creating and governing the Ghoul Stomach World. 617 702 723 1241 1301
