Jinyi Chen Qianhu, the Best Demon-Slaying Sword in Fusi, Beizhen

Chen Feng opened his eyes and found that he was in prison. Just because the emperor dreamed of being strangled by more than a dozen maids. There is no system, no golden finger, only a demon-slaying knife. Coming from the Infinite Immortal Capital, fighting all the way to the Abi Hell, Western knights and Eastern swordsmen are all a thing of the past. This world is really too lonely. Three years later, he was asked how to save Ming Dynasty. Answer: Set up another governor, named the Governor of the Seven Seas. He will sail with you, launch huge ships into the sea, and use divine machines and artillery to strengthen our country's power and make the Ming Dynasty great again.
