Quickly Travel Through My Heartthrob Straight Male Host

[Two male protagonists + quick travel + 1vN + Shura field + heartthrob + main subject] The book's ratings were not high when it first came out, but they will go up later. Qin Shu bound the Zha Gong playing system to travel through various worlds playing the role of Zha Gong. There is no original owner, it has always been the protagonist. The first world. Qin Shu traveled through time and became a scumbag who abused the protagonist physically and mentally in the early stage and then treated the protagonist to death in the later stage. The second world… No, I'm such a scumbag. Why do the people around me look at me more and more wrong?
