Biodata

Power Progression

Background / History

Gu Ci awakens his Martial Soul at age six, unexpectedly evolving it into the Super Martial Soul Thunder Prison Heaven-Slaying Tiger alongside his secondary Heavenly Eye and attaining Innate Full Soul Power 3. Partnering with Dugu Bo and his family, he enters the Sunset Forest to successfully contract his first Soul Spirit, the Purple-Winged Thunder-Scaled Tiger (Zi Dian) 11. After curing Dugu Yan's long-standing toxins 14, he consumes the Purple Sky Thunder Orchid at the Ice and Fire Dual Pools to elevate his thunder attribute to Ultimate Thunder 16.

Over the following years, Gu Ci contracts three additional powerful tiger-type Soul Spirits (Night Shadow, Thunder Emperor, and Silver Crown) 21 55 82, founds the advanced technology hub known as the Heavenly Workshop 39, and joins the Heaven Dou Empire's military to defend Cangyun Pass against the Star Luo Empire 64. Chosen as the successor to the Thunder God, he successfully passes the first two divine trials—reaching Level 50 and forging a Fifth-Grade Soul Armor—while building the Heaven Dou Royal Academy team into an elite force for the continental tournament 91 116.
