People in Hongwu, from Heavenly Master to Imperial Master

In the first year of Hongwu, Zhang Yi, who had traveled through time, accompanied his father, Zhang Changchang, the Celestial Master of Longhu Mountain, to the capital to meet the emperor. The emperor took the title of Celestial Master of Longhu Mountain, but kept Zhang Yi, who had predicted the future, in the capital in another identity. His father returned home depressed. Before leaving, he begged Zhang Yi to take back the title of Heavenly Master in Longhu Mountain. However, he never thought that this child would completely change this centuries-old dynasty in the future. He said in front of the emperor that the officials and dogs of the Zhu family were unworthy, and also used a world map to ignite the emperor's ambition, tricking him into sending Zhu family's descendants all over the world. He had a close relationship with the prince and taught the prince how to give birth to a child. Discussed with Liu Bowen, taught Yan Shenggong the art of slaying the dragon, how to slay the Confucian dragon... Many years later, the emperor revealed his identity and asked: You have changed the world, what do you want? Zhang Yi remembered his father's instructions: Your Majesty, can I take back the title of Heavenly Master in Longhu Mountain? The emperor replied: There is no heavenly master in Longhu Mountain, but there can be one more national master!
