MTL - For Thousands of Years, My Weakest Brother Has Become a Demon King (1000 Years Later, Even My Weakest Follower Has Become A Demon King) - Chapter 23 kill you

The author named me Wei Changcheng, also known as Wei Great Wall.
I really defended the Great Wall. I managed to climb the Great Wall extravagantly, but I was squeezed down from the Great Wall. Even if I crossed it, what kind of trouble did I have to attach a system?
It’s fine to have a system as a bonus, but what kind of trouble is it going to be annoying wherever it goes?
“In Harmony…”
What? You still have to “eat” the system? Have a lot to eat? I’ll just call you an idiot from now on!
What? You want to be my partner? “In Harmony…”! Why are you pressing me? Hehehehe, my original form can climb trees, can you?
