One moment, everything was normal. Then the World Core woke up and slaughtered almost everything alive so it could harvest their Chi.
After that, it rebuilt everything and put the survivors in a game-like environment, pitting them against monsters and each other.
The rules are different now. Chi power is as important as being able to fight.
I'm one of the survivors. With my knowledge of martial arts and my special Chi skill, I'm turning myself into a force to be reckoned with.
And the women I meet along the way?
Let's just say there's more than one advantage to joining my party.
This is a western cultivation fantasy adventure that includes a definite sense of progression and Gamelit/LitRPG elements. It contains the complete trilogy.
