Chapter 524: The Strongest Experts in the Two Worlds

Meng Chuan, Qin Wu, and Luo Tang looked at Li Guan.

At that moment, Li Guan looked extremely old. His hair was snow-white, and his face was covered in wrinkles. He was nearing the end of his lifespan, and his age was apparent.

"Senior Brother, you have sacrificed plenty for Archean Mountain and humanity all these years," said Qin Wu solemnly.
