Desolate Era - Book 44, Chapter 26 - Unstoppable

Chen Lin traveled through the martial arts world and found that he actually had a clone, but…

“Why is my clone in the world of immortality?”

“Forget it, you can continue to practice martial arts. I am going to start cultivating immortality. I will meet you all again in a thousand years!”

…

Over the course of thousands of years, there will always be geniuses born from the sky, whose fame is as mighty as the sun, sweeping across the universe.

But no matter how heroic the Martial Emperor is, when they burn out the emperor’s blood and exhaust their souls, they finally break through the world of mortals with their withered and broken bodies, penetrate the layers of divine patterns and talisman formations, and see the figure standing at the end. …

The person who stands on the twelve-level lotus platform, wears the Mountains and Rivers Sheji Diagram, holds the Jade Order of Creation in his left hand, hangs the Four Swords of Killing Immortals in his right hand, and hangs the shadow of the Tai Chi Diagram behind him, will always turn around.

He smiled cheerfully and said to them:

“Coming?”
