In the spring of the thirteenth year of Hongwu, Prince Zhu Biao woke up from a high fever that lasted for three days.
When the attendant shouted in surprise, "Your Highness is awake," two centuries of technological history were rushing through his mind.
Lin Yuan looked at the young but pale face in the bronze mirror and realized that he had become the kind-hearted prince who died young in the history books.
A report came from outside the palace: Jiangbei plague has spread to outside Yingtian City.
He pushed away the medicine bowl and grabbed a pen - the preparation process of penicillin clearly appeared in his mind.
"Send the order," his voice was hoarse but firm, "Take the moldy summer melon, prepare vegetable oil, charcoal powder... And isolate the sick and boil the water."
The old imperial doctor was dumbfounded.
The prince who behaved strangely after waking up did not know that the prescription he wrote would shake up the entire world during the Hongwu period.
