You've Become a Mature System

I'm a mature System now. I can cultivate on my own, so you don't need to worry about me, Dad. Jiang Liu transmigrates to a modern city much like one undergoing a spiritual qi revival, where he activates a miraculous System: it cultivates by itself, levels up and grows stronger on its own, and even crafts equipment by itself... And so

Jiang Liu leaves it running overnight and wakes up to find that it has leveled up.

Jiang Liu leaves it running, and it keeps going... Holy crap, I challenged the world's number one expert! Damn it, can I take that back?
