You Are Already a Mature System

I am already a mature system, I can practice on my own, and I don't need you to worry about it, dad. Jiang Liu traveled to a modern city that was similar to the revival of spiritual energy, and activated a magical system: it could practice on its own, upgrade and become stronger on its own, and equip itself... And so—— Jiang Liu hung up all night, woke up and upgraded. Jiang Liu hangs up, hangs up, hangs up... Fuck, I'm going to challenge the best master in the world, damn, can I still withdraw this?
