Synopsis:

The premise of the story goes something like this:
The Demon King who recently ascended to the throne, by mistake, attacked the Princess of the human kingdom(this was due to shock of how ugly she was) which made the humans send their most powerful heroes to kill him.
The Demon King at first believes he can beat the Heroes only to learn by his assistant that it is fate for all Demon Kings to be killed by the Heroes.
To avoid that, the Demon King needs to level up and be more powerful than the Heroes sent to kill him.
However, there aren't many high level heroes for him to kill and get EXP so the Demon King decides to raise low level heroes and help them level up until their levels are high so he can kill them for their EXP.

This is a pet peeve of mine but I wish that one day we can graduate from these "usual questions" that are:

Is the MC op?
Is it harem?
Is it snusnu? (webnovels)

It's like people don't even start reading if they can't answer all of them with yes.

Do you mean answer with no instead? Any one of this question will make me stop reading if answered with yes.
It doesn't seems like this another of the same reincarnated, OPed, get all those 1/100000 abilities, harem series.
Anyway, training heroes to be stroner... isn't it the kind of hubris that gets demon king defeated in rpgs?

is this also based from a novel?

^arent all such mangas based on them?

No. It's a original Chinese Manhua parodying the Demon King genre.

is he f**k the girl?

Definitely. Someone needs to get this guy a copy of the Evil Overlord List... Just kill the prospective heroes before they ever have a chance. One at a time, if possible. The path he's on now, he's doomed to either be defeated by his heroes, or even worse, be turned by the main heroine.

^Except there's one hero who stronger than the Demon King and is after him.
Hence the Demon King's plan of raising weaker heroes levels who he will kill later after they gain higher levels so he can level up faster so he can defeat the one hero who is after him.

chapter 11 is out and the series is getting better every time i read it.
