章 402: Underworld Devil Killer Wasps

After all, the oldest history recorded by humans was only around five thousand years old. Moreover, the humanity after the Dark Ages didn't even attach itself to that history much.

But that wasn't important. The most important line caught by Li Yunmu from the system's words was that no living creature had entered the cave for last eight thousand six hundred years. 　

Why was that?

This abnormality caused Li Yunmu to become concerned. There were countless unknown and mystical events happening all the time in the Origin World. It was a boundless world which possessed extremely ancient history.

Even a deity wouldn't dare to make claim that he could run amuck in the Origin World without any fear, let alone someone like Li Yunmu. One had to always remain cautious, or they wouldn't even know how they died.
