“Can’t I properly read stallion novels anymore!”

Shen Yuan transmigrated into someone who’d tormented the young male lead almost to death, the scum villain Shen Qingqiu.

It must be known, the original Shen Qingqiu ended up being carved alive by his disciple, Luo Binghe, into a human stick, a human stick!

Ten thousand “fuck your moms” rampaged through Shen Qingqiu’s heart:

“It’s not that I don’t want to cling to the male lead’s thighs, but who made him so fucking black. The type who seeks thousand-fold retribution!”

Why have all the female lead’s scenes been forcibly given to him.

Why, as a scum villain, does he need to constantly sacrifice himself, blocking knife and gun for the protagonist!

Shen Qingqiu: “…I think I can still save him, one more time.”

A gong who starts as a loyal dog of a small white flower, and ends up as a blackened, mental case of a maiden X a refined scum villain of a tsukkomi-holic shou

This is actually a dogblood story about a master-disciple pair never doing honest work, fighting monsters, and engaging in romance.

It’s also a story where the villain personally witnesses how the male lead transforms from a little sheep of a white lotus into a dark tyrant O(∩_∩)O~
