Li Ruochen, an ordnance manufacturing expert in the 21st century, accidentally traveled back in time to the son of the Shanxi warlord Li Fuying in 1932. After the Central Plains War, he entered the Whampoa Military Academy. When he came back five years later, he found that he had a daughter.
Li Ruochen produced a large number of weapons with manufacturing technology that is 70 years ahead of the world. Anyone who offends China will be punished no matter how far away he is.
