Chinese title: 人渣反派自救系统
Can’t I read stallion novels anymore?! 
Shen Yuan is reborn into a young man and scum villain destined to die, Shen Qingqiu.
But it must be known that the original Shen Qingqiu was sliced alive by his disciple, Luo Binghe, into a human stick! A human stick! 
Shen Qingqiu’s heart is a full herd of grass mud horses  running full tilt, yet:
“It’s not like I don’t want to hug this main character’s thighs, but who let this fucking man be so black . The revenge that needs to be taken is some thousands of deeds!
Why is all the romance that should be going to the women in the plot imposed on him?
Why as a scum villain, should he still have to block gun and knife for the protagonist and sacrifice himself?
Shen Qingqiu: “…… _(:□)∠)_I think I can still save him one more time.”
He wants to prove – even scum villains can live, and live coolly at that!
It’s also the story of a small white flower who later became a black flower attacking a scholarly, scum villain type.
This is the story of a master and disciple’s everyday unknowing, very strange, dog-blood process of falling in love.
It’s also a scum villain’s firsthand account of the male protagonist turning from a small white sheep into an overbearing black king, sort of story……
 Stallion novel: Meaning the genre of novel with an overpowered protagonist and harem (I think).
 Human stick: An ancient form of torture. All four of the person’s limbs are removed, leaving only the head and body to form a ‘stick.’
 grass mud horses: These Chinese characters strung together make up a homonym for an expletive. Shen Yuan is basically saying ‘fuck to the umpteenth degree.’ XD
 black: In this case, evil and/or sly.
My own straightforward summary:
The story of a guy who transmigrates into the scum villain of one of those harem xuanhuan/xianxia novels. The scum villain, Shen Qingqiu, is one of those looks-noble-but-is-actually-a-hypocrite types. Shen Qingqiu’s disciple is the ‘main character’ of the novel (Luo Binghe) who gradually turns blacker the more tragic things happen to him.
With the help of a very troll system, the new Shen Qingqiu tries to stay alive by staying on Luo Binghe’s good side (the original Shen Qingqiu was very mean to Luo Binghe, hence his terrible ending). However, heroes grow through adversity and Luo Binghe… definitely has a lot more tragedy in his future. And Shen Qingqiu’s system limits his actions.
The sometimes-angsty but also very touching story of a master and disciple. This novel contains BL that verges into yaoi only in the last chapter or so and in some extras. No harem though there are mentions of original!Luo Binghe’s harem. Very slow build romance but definitely worth the wait.
