I Don't Know If I Have a System, but I'll Definitely Find a Way

My name is Jiang Yanyu. You may not know who I am, but I'm about to make a bold claim.

I, Jiang Yanyu, am destined to become the world's last King of Bragging!

P.S. Where's my System? What's the point of playing without a System? How am I supposed to cultivate immortality?

If you don't give me a System, I'll pry open your skull! I'll smash your head in!
