In the ninth year of Guanghua, Ling Yun transmigrates to the Jiuli Empire and becomes a lowly prison guard in its vast Heavenly Prison.

This empire, which had lasted 637 years, was already on the verge of collapse before Ling Yun arrived.

As a prison guard, Ling Yun can only keep his head down and constantly worry about his own future.

But after awakening the Tomorrow's Star System, his life changes dramatically.

Twelve years later, people suddenly realize that the man who walked out of the Heavenly Prison is the greatest power broker in the history of this world!
