Yongle Emperor Is My Brother-in-Law! Let’s Go—Just Keep Being Careful!

He stumbles onto a huge stroke of luck and transmigrates, becoming Xu Huizu, the eldest son of Xu Da, Duke of Wei of the Ming dynasty.

What? His brother-in-law is the future Yongle Emperor, Zhu Di?

Isn’t that just a matter of lying low and surviving?

So then...

In the Hongwu era, keep a low profile and crawl along!

In the Yongle era, my brother-in-law is Zhu Di!

In the Hongxi era, nephew, you handle it!

In the Xuande era, brat! I’ll help you settle the crown prince!

...

Zhu Yunwen: I’m going to abolish the princely fiefs!

Xu Huizu: Good! There will no longer be a Yan Prince Zhu Di in this world!

Zhu Yunwen: Weren’t you supposed to help me abolish the fiefs?

Xu Huizu: Just tell me whether the Yan Prince is gone or not!

Zhu Yunwen: He is gone. He became the emperor!

...

An absurdly long-lived rebellious son system; if you mess with your father, you can live longer.

A lighthearted comedy + devoted to the Ming + harmonious + invincible + lying-low style.
