MTL - Summoning In the Snow, My Harem is Too Dangerous - Chapter 264

The poor Commandery Princess is down and out. Her father died when she was young, and her mother passed away not long ago. Her grandfather, the only one she can rely on, is now at death’s door from his illness. Faced with the merciless uncle, the greedy aunts, as well as cousins competing to present the model of the worst relatives, the Commandery Princess could do nothing but feel depressed in heart.

Reincarnated as the eldest son of Ming Taizu Zhu Yuanzhang, the biological father of Emperor Jianwen, and the elder brother of Ming Chengzu Zhu Di.

See how Yiwen Prince Zhu Biao, who was fleeting like a meteor in history, survived the turbulent Hongwu years and built a new Ming Dynasty!
