"Not really high in martial arts, but he spent thousands of years going mad on Earth Demon Island, reading a lot of books, gaining a lot of knowledge. I had a secret book; he could understand it. He helped me decode that book. He was once the ally of the Red and Black Demon King and taught him, so he has some insight," Ye Chen explained.

"How did you meet him?"

Ye Chen glanced at Guo Yuyun and replied, "This girl was there at the time."
