Douluo Dalu: This Life, I'm Done Being a Simp

When he awakened memories of his previous life at eighteen, his nemesis Tang Wulin was only eight. With the help of the Heavenly Phoenix Douluo, he was reborn through nirvana as an eight-year-old boy the same age as Tang Wulin. Under the assumed name Qiangu Shu, he became the illegitimate son of Qiangu Dongfeng and Leng Yaozhu. In one extraordinary leap up the family tree, he became his own great-uncle. From then on, he would take the protagonist's path and leave the protagonist with nowhere to go.
