Oh No! My Little Brother Is Li Shimin

Li Kai transmigrates into the setting of a fictional game, becoming a crown prince whose situation is anything but ordinary.

To put it simply, his five younger brothers are:

The second son, Li Shimin; the third son, Yang Guang; the fourth son, Yin Zhen; the fifth son, Cao Zhi; and the sixth son, Cao Chong.

And that is not even counting his father-in-law, Yang Jian; his kind teacher, Sima Yi; his trusted aides, Huang Zicheng and Qi Tai; his personal eunuchs, Zhao Gao and Wang Zhen; or the Eastern Palace guards, Li Jinglong.

The worst part is, his wife is Jia Nanfeng?!!

Worse still: "You mean I have to achieve the 'Become Emperor' milestone before I can leave?!"

Coming soon: "Father, Open the Door, I'm Your Brother"

My name is Li Jiancheng, and I'm a crown prince.

During the Xuanwu Gate Incident, my little brother, Er Feng, killed me.

But no worries. Twenty years later, I'm a hero once more.

I opened my eyes and found myself transmigrated.

The good news: I'm still a crown prince...

The bad news: My father is Li Shimin?!

Well, I'll be. I've transmigrated into that kid Li Chengqian.

Being crown prince is overrated!
