My Father, Song Taizu, Started Developing Penicillin

He traveled through time and became the second son of Song Taizu, Zhao Defang! The start seems to be unfavorable. His biological father is in a coma, and his uncle Zhao Guangyi is eyeing him. Zhao Defang, who is familiar with history, knows very well that once Zhao Guangyi becomes emperor, his ending will be very miserable. Zhao Defang, who came from time-travel, smiled, "My father can be an emperor wearing a yellow robe, so can I." With the knowledge brought from time travel, he developed penicillin, steel smelting, flintlock guns, and gunpowder, allowing the Song Dynasty to enter the Age of Discovery ahead of schedule!
