(No female lead, two strong leads. There is a secondary couple, so feel free to guess.)
Yuan Jinghuan, a professional villain who has transmigrated through more than two hundred worlds, receives yet another assignment just as he's about to retire.
The male lead in this world has no wife and a serious illness.
And to top it off, Yuan Jinghuan arrives at the wrong point in the timeline!
As if arriving at the wrong point in the timeline weren't enough, this Yan Yao is practically not a carbon-based life form!
Someone tell him! How can anyone combine being handsome, expressionless, thick-skinned, and talkative all at once?
What kind of ridiculous character design is this?!
Yan Yao: (t.T) Other people chase their wives until they end up in the crematorium. I'm the one being chased to the crematorium.
Yuan Jinghuan: Get lost.
(This story includes xianxia and sci-fi, but the worldbuilding is very simple. I couldn't find a suitable tag in the categories, so I just picked one. Please don't flame me.)
Theme: If you begin to doubt everything around you, then from a certain perspective, the whole world is fake
