Viewing the Tang Moon from Thousands of Miles

People not only have to fight for the long term, but also fight for the day and night. Tang Yun, who has been working as a system developer for half his life, understands this truth best - especially when he opened his eyes and found that he had become a refugee outside Tongfu Town in the late Sui Dynasty with no household registration, no road guide, and no grain of surplus food. The most indispensable thing in troubled times is reasons why he can't live. He only has two pages of old paper filled with codes and flow charts, a head that has been filled with countless system architectures, and a skin that has been moving extremely slowly since the day he traveled through time. The oil lamp in the side hall was dim. Lieutenant Li put the tea bowl on the table and looked like a hook: "If I want you to produce salt, go to Taiyuan for me, do you dare?" Tang Yun lowered her eyes and thought about the pros and cons three times. Going to Taiyuan is a pit of fire; not going is a dead end. He spoke slowly: "Your Excellency, you think highly of me. If I really had the ability to travel around, I wouldn't be starving and fainting in Tongfu Town." Lieutenant Li smiled. This smile sent chills down the spine even more than falling out. Tang Yun returned to the east wing, closed the door, and sat down against the door panel in the dark. He knew that from tonight on, every pot of salt he cooked would help him earn his own life; and the thought in his heart that he wanted to live a stable life was destined to push the entire Tang Dynasty forward step by step. He improved agricultural tools, set up schools, reorganized medical centers, improved ordnance, and saved several famous ministers and virtuous empresses who should have died young, and then let the wise and martial brother-in-law Li Shimin get away. He doesn't want to fight, he just wants to live comfortably. The problem is, he never seems to get a full night's sleep.
