No One Returns from Hexi

In the winter of 382 AD, outside Yumen Pass. Fu Jian sent Lu Guang to march westward with 70,000 soldiers and 5,000 cavalry. No one knew that when this army came back, the Central Plains was shattered and they were homeless. In a sandstorm, the leader of a fifty-man team took over the memory of another person sixteen hundred years later, and a mobile phone that could no longer be charged. He could not bring back the "Wu Mu's Suicide Note", nor could he make gunpowder. He only has one thing - He knows where the water is. Which dry river bed has seepage three feet below, which Han canal can still be used, when will the snow water from the Qilian Mountains come down, and which way will it go. In the Hexi Corridor, where the annual rainfall is less than 200 millimeters, this is not called a golden finger, but a fate. 70,000 Exhausted soldiers, without food, without status, Liangzhou governor refused to accept them. Everyone was waiting for him to beat Gu Zang. He turned around and went to Zhangye - there was an old canal from the Han Dynasty that had been buried by wind and sand for two hundred years. He knew that it could be reclaimed within three months. After the autumn harvest that year, no one asked him why. From a team leader, to the leader of Hexi, to Guanzhong, to the world. But what this book really wants to ask is not how far he can go. He once saved a man who should have died from slander. The man survived, only to die seven years later in an ambush he never expected. History is not a piece of iron wire that can be bent. It's the Black River - you block it upstream and it breaks out somewhere else downstream. The entries in the mobile phone will be atomized one by one. When the screen was lit for the last time, the one about himself was blank. From then on, he walked in darkness like everyone else in the world. This time, he wanted to write it himself.
