In an accident, Zhu Zhan took the memory of his previous life and traveled back to Emperor Tianqi, Zhu Youxiao, who had just fallen into the water and died.

As a graduate student in metallurgy and a sweeper at the Artillery Research Institute in his previous life, let's see how he relied on his own knowledge and understanding of history to make a decadent Ming Dynasty take off.
