Iron-Fisted Minister

He doesn't know martial arts, but the top master in the world is willing to be a common servant and just give him a bowl of food. He has no official status, but he is a high-ranking official, but he asks his relatives and friends to be his master. He must take care of his own food and accommodation. However, all this is not his highest ideal. He must rely on the absolute advantage of the time travellers to start a road to the defeat of alien rule!
