Save-Yourself-System for the Main Villain. Volume 3

To save his school from destruction, Shen Qingqiu agreed to the demands of Luo Binghe.
Shen Qingqiu longs to return to the peaceful days he spent with his student on the peak of Qinjing, but that is impossible. Luo Binghe has turned into a true Demon Lord, and now he must confront his own father.
The further it goes, the more secrets of the "Path of the Proud Immortal Demon" are revealed to Shen Qingqiu... including the past of the current master of his body. And he realizes that he must accept Luo Binghe as he is. Otherwise, they both will perish... And perhaps the whole world with them.
