Where Did Zongman's Sky Screen Come From?

My name is Invincible. I don't remember my name very clearly in my previous life either. Since I was born on this earth, my strength has been increasing all the time. I always thought that through this power I would be able to do anything, and that's how I've always done it. But what happened? Where did the marquee come from after I was 15 years old? What was put there? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
