After the death of Emperor Yongle, his soul remained, floating in the void for three hundred years. He watched with his own eyes as the Ming Dynasty was hollowed out by capital and bureaucracy—the Liao Dynasty paid off the enemy, the emperor was poisoned, and all the classics were burned. Returning to the Xuande Dynasty, he poured three hundred years of memories into Zhu Zhanji's consciousness. The two generations of emperors joined forces to tame capital and rewrite history, starting from building cages. This is not revenge, but creating a world that will never rot again.
