Background / History

Xu Sanshi enters Shrek Academy’s Outer Court as Bei Bei’s roommate. He immediately forms a lively, competitive dynamic with Bei Bei, repeatedly challenging him despite being outmatched in their early spars. A body scan identifies him as a level 31 Soul Elder with physical strength above his soul-power level and latent Black Tortoise divine-beast bloodline. 31 33 34

During the Freshman Assessment final, Bei Bei deliberately provokes him into anger to stimulate his martial soul’s origin. Xu Sanshi briefly awakens the true Black Tortoise, discovering both its divine-beast power and the weakness caused by forcing the transformation. 51 52

He later achieves a complete awakening of the Black Tortoise martial soul. The evolution grants him Ultimate Water and upgrades his displacement skill; he also learns to combine his first three soul skills into Black Tortoise Roar. 78 104

By the Continental Advanced Soul Master Academy Soul Fighting Tournament, Xu Sanshi serves as a major defensive and disruptive member of Shrek Academy’s lineup. He defeats three Soul Ancestors using roughly thirty percent of his strength, then later kills Li Yan and Chen An in the individual elimination round. 98 115 116

Xu Sanshi is a physically robust boy whose build becomes taller and more muscular when channeling the Black Tortoise’s power. 33 52

• Height: 1.75 meters at age twelve. 33
• Weight: 70 kilograms at age twelve. 33

Personality

Xu Sanshi is playful, boastful, and shamelessly flirtatious. He enjoys teasing Bei Bei, showing off after victories, and exploiting match rules through tricks such as displacing opponents beyond the arena boundary. 31 36 78 98

Beneath his unserious façade, he is highly competitive and determined to become the strongest defensive Soul Master. Defeat by Bei Bei motivates him to improve, while serious combat reveals a forceful and intimidating side that even his teammates find striking. 34 51 115

He initially pursues Jiang Nannan persistently after learning the circumstances of their prior transaction, driven by guilt and affection. Over time, he earns her acceptance and becomes her boyfriend. 79 162
