An Yan was unemployed. He went home to rest and was taken on a blind date by his mother. He had no car and no house and was ridiculed by the woman. When he returned home, he was soaked in the heavy rain. He was completely unlucky. Going up the mountain to relax, I accidentally discovered a time and space gate. On the other side of the time and space gate is an endless desert. An Yan opened an inn in the desert and found that the business was pretty good, but the customers were a bit strange. There are knights and swordsmen in ancient times, warlords and bandits during the Republic of China, and interstellar travelers from the future. As a dead otaku, An Yan became a witness to each story. His modern life was getting better and better, and he was gradually helping his country become stronger and stronger.
