Douluo Continent: The original Yu Xiaogang brutally defeats Tang San at the start.

In a shocking turn of events, Lin Yuan finds himself transmigrating into the body of Yu Xiaogang, a character from the novel *Douluo Continent*. However, instead of inheriting Yu Xiaogang's supposedly invincible abilities, Lin Yuan is bound to a system with a ruthless purpose: the more pain Tang San suffers, the stronger he becomes. As Tang San strives to become a Grandmaster's disciple, Lin Yuan coldly rejects him, deeming him unworthy. This rejection sets in motion a series of events where Tang San's reputation is tarnished, his relationships are turned upside down, and his very existence is threatened. With Lin Yuan's manipulation, Tang San's past accomplishments are ridiculed, his techniques exposed, and his loved ones, including childhood sweetheart Xiao Wu and trusted allies Zhu Zhuqing and Ning Rongrong, are drawn to Lin Yuan, addressing him as "Teacher." As Tang San's world crumbles, he is driven to the brink of despair, screaming in anguish at the injustices Lin Yuan has inflicted upon him.
