Transformed into the fifth son of the Ming Dynasty, facing Zhu Yuanzhang, the irascible father who started with a bowl and whose ultimate skill is "beheading", Zhu Rui decided to carry out "madness" to the end. When his brothers were competing to demonstrate their martial arts skills, he held his chest and said to Zhu Yuanzhang: "Father, my son is sick, and I just want to open a small hospital and live a life." All the civil and military officials in the dynasty thought King Zhou was crazy.

Zhu Yuanzhang fell into deep thought as he looked at the civil and military officials kneeling down to beg the miracle doctor for help. He held a knife and found Zhu Ji who was tinkering with penicillin in the laboratory: "Lao Wu, tell me the truth, your hospital... Can it guarantee immortality?"
