From the Start, I Reveal the Jingnan Campaign: Zhu Di Begs Me to Leave the Imperial Prison

The Yan army breached the city, and the Hall of Heavenly Mandate became a sea of flames.

Prince of Yan Zhu Di kicked open the prison door with a saber in hand, only to find the condemned prisoner Lu Ming calmly drinking wine. Behind him, a prophecy had been carved into the stone wall half a month earlier:

[At the third quarter of the Horse hour, Jinchuan Gate will open. Flames will engulf the palace, and the Prince of Yan will take the throne!]

The all-conquering Yongle Emperor sheathed his saber and bowed deeply. “Please, sir, teach me how to secure this vast empire!”

…

Having lived for a thousand years, Lu Ming only wanted to take it easy. He had kindly advised Jianwen to give up, only to end up in prison, so he might as well wait for the new emperor to take over.

He could barely lift a chicken, and when he scraped his skin in a fall, everyone was heartbroken, imagining: “The master revealed Heaven’s secrets and was punished by Heaven, stripped of all his immortal powers. I will protect him at any cost, even if it means mobilizing the entire empire!”

Two streams of water broke the deadlock over the campaign to abolish the fiefdoms, and he talked the demon monk Yao Guangxiao into submission. Cement fortified the frontiers, and cannons pacified the northern deserts.

As Zhu Di stared at him in bewilderment, Lu Ming casually tossed out a map of the world and yawned:

“Your Majesty, you’re thinking too small. The sun and moon of the Great Ming should never set.”
