Great Ming: Don't Mess With Me, My Brother Is Zhu Zhanji

He transmigrates to the Yongle era of the Ming Dynasty.

Zheng Xi becomes a spoiled son of the Marquis of Wu'an, a good-for-nothing who causes trouble wherever he goes.

One day, he sees the error of his ways and vows to turn over a new leaf.

By a twist of fate, he becomes sworn brothers with Zhu Zhanji, the emperor's eldest grandson.

From then on, he establishes himself at court, looks beyond the realm, and builds a very different Great Ming.

Emperor Chengzu of Ming, Zhu Di: "Zheng Xi is a rare talent. It hardly lowers the imperial grandson's status to be his sworn brother."

Zhu Gaochi: "Zheng Xi has plenty of clever schemes. Ask him about governing the country."

Zhu Zhanji: "My brother changed the Ming Dynasty. He deserves to be made a prince!"

Yao Guangxiao: "Zheng Xi is far too slippery. The farther you stay from him, the better!"

Xie Jin: "Your Majesty, Zheng Xi is competing with the people for profit. Please punish him."

Yang Shiqi: "Zheng Xi is immensely talented, yet utterly without morals. He's a ruthless schemer."

Mahmud, leader of the Oirats: "That bastard Zheng Xi is here! Surrender, quickly!"

Arughtai, leader of the Tatars: "...Zheng Xi again... Forget it, let's admit defeat!"
