The modern social beast Li Tiezhu died suddenly and was reborn in the Tang Dynasty. He was bound to the "anti-Japanese and national salvation system" and relied on the fancy counter-espionage method of "beating the Japanese to gain skills". He eliminated Japanese undercover agents, renovated warships and upgraded firearms, led the Tang Dynasty to conquer the Japanese army across the sea, and turned Japan into a silver workshop of the Tang Dynasty. Along the way, there are a lot of jokes, jokes, and life-and-death showdowns. Watch the old man from Northeast China bring skewers and systems to beat the old days and protect the glory of China in ancient times!
