Emperor Jianwen, Zhu Yunwen, has six hundred years of memories, two secret edicts from Zhu Yuanzhang, and the life of his eleven-year-old son to protect. Starting with his escape, he works backward to counter Zhu Di, move the capital to Beiping, and build a Ming fleet. In the end, he spreads the words “wherever the sun and moon shine” across half the globe. The Yongle Golden Age? He’s the one who set it in motion.
