Skeleton Knight, in Another World - Chapter 18Volume 2 -

My reunion with her took place in the worst possible way.

If you can reincarnate or transmigrate into a cultivation novel world and you have a choice, would you be a protagonist, an antagonist, a side character, or a mob character?

And what would you do if you are aware that you’re a character in a cultivation novel?

Mao Miaomiao, a 60-year-old retired professional MMA fighter got transmigrated into a mysterious cultivation world with modern technologies. He found himself in his youthful body, and he got a system as a bonus.

Cliche, right?

Follow Chen Ming as he accepts disciples, establishes a sect, and fights his way in a world that deems him a cannon fodder.
He goes against any common sense using his wits and novel knowhow to finish missions and arm himself against his cruel fate.
