His soul traveled through the Ming Dynasty and became the poorest royal family member. Zhu He just wanted to rely on his engineering knowledge to make a little money and become a local landlord in the capital.
But the briquettes he produced were regarded by Emperor Jiajing as "immortal treasure charcoal"; the white sugar he purified was regarded as "manna from heaven".
Zhu He was completely panicked. The more he tried to explain that this was science, the more the emperor, who was dedicated to cultivating immortality, felt that he was "testing his Taoist heart", and chased him with a fanatical look on his face, shouting "Fellow Taoist, stay!"
From solving the severe drought in the capital to toughening the Mongolian cavalry, Zhu He was forced to dance crazily on the tightrope of "falling off the horse and dying". By accident, he turned the crumbling Ming Dynasty into an empire on which the sun never sets.
