Background / History

Xu Sanshi was Shrek Academy Outer Court's most renowned defensive student, known for the Black Tortoise martial soul and his confidence in its supposedly unmatched protection. When Gu Chen challenged the academy's strongest student for admission, Xu Sanshi accepted while openly dismissing Gu Chen's Blue Silver Grass martial soul. He intended to defeat Gu Chen quickly, especially with Jiang Nannan watching. 4

Gu Chen shattered Xu Sanshi's Black Tortoise Shell Shield with one punch, then broke his hand, bound him, and knocked him unconscious. Xu Sanshi's rage caused his Black Tortoise bloodline to awaken into Blackwater Xuanwu, but Gu Chen stripped away his water-element power, sealed his martial soul, and defeated him again. 4 5

The loss became an obsession. A month later, Xu Sanshi challenged Gu Chen again in a restaurant, claiming that his prior loss resulted from carelessness. Although he admitted Gu Chen's bloodline and elemental control surpassed him, he refused to lower his pride; Jiang Nannan had also told him not to see her again until he defeated Gu Chen. 9

After reaching Four Rings, Xu Sanshi began competing in the Soul Fighting Arena and won through Black Tortoise Substitution. Provoked by insults comparing him to Gu Chen, he loudly sought a rematch. 25 26

Gu Chen instead disguised himself as the “Golden Dragon Princess” and challenged Xu Sanshi. Captivated by the disguised Gu Chen's appearance, Xu Sanshi ignored Bei Bei's warning and entered the match eagerly. The Golden Dragon Princess shattered his shield a second time, seriously injured him, and left him unconscious without revealing her identity. 27 28

Personality

Xu Sanshi is exceptionally prideful and reacts violently to humiliation, especially when Gu Chen is mentioned. His first defeat left him unable to accept the gap between them, turning Gu Chen into the focus of his desire for revenge. 4 9 26

He is also impulsive and easily distracted by attraction. His infatuation with the Golden Dragon Princess made him disregard both Bei Bei's caution and his own stated attachment to Jiang Nannan, directly contributing to his second crushing defeat. 27 28
