The Scum Villain’s Self-Saving System: Ren Zha Fanpai Zijiu Xitong Vol. 1

*Official English Translation*

Half-demon Luo Binghe rose from humble beginnings and a tortured past to become unrivaled in strength and beauty. With his dominion over both the Human and Demon Realms and his hundreds-strong harem, he is truly the most powerful protagonist...in a trashy webnovel series!
At least, that's what Shen Yuan believes as he finishes reading the final chapter in Proud Immortal Demon Way. But when a bout of rage leads to his sudden death, Shen Yuan is reborn into the world of the novel in the body of Shen Qingqiu--the beautiful but cruel teacher of a young Luo Binghe. While Shen Qingqiu may have the incredible power of a cultivator, he is destined to be horrifically punished for crimes against the protagonist.
The new Shen Qingqiu now has only one course of action: get into Luo Binghe's good graces before the young man's rise to power or suffer the awful fate of a true scum villain!
