Xuanjian Is Still Awake

In the third year of Zhenguan in Chang'an, camel bells rang and the gates closed at dusk. When Gu Heng woke up, the hum of the GPU in the computer room had been replaced by the smell of horse manure and spices. He is an AI algorithm engineer, and there is a light cyan mark on his wrist - it is the artificial intelligence "Xuanjian" that he spent five years training and training. It has only 0.003% Energy left and will be permanently silent at any time. He has no money, no household registration, and cannot speak Tang Dynasty Mandarin. He thought time travel was just an accident. He thought the priority was just to survive. Until Xuanjian suddenly burned hot in the middle of the night, and the writing on the retina was as red as blood: Historical offset signal detected. Source: East of Chang'an City, Xingqingfang. Target identity: Li Shimin. Event window: seventy-two days. Gu Heng's back felt cold every inch. He's not the only one in this era with something from the future. Some people came earlier than him, and some brought weapons instead of knowledge. Another time traveler, "Xu Wujiu", is using a time anchor to rewrite history. He wants Li Shimin to die at the "right time" and let Datang move towards a "better future" according to his script - the price is that every living person at the moment is just a data point on his chessboard. Gu Heng only has a magnet, a coin, and an AI that may burn out at any time. What he wants to fight is a revisionist who has been planning for twenty years. What he protects is not the throne or power - it is the right of "people to make their own choices." The future you see is just the probability calculated by others. And the path he chose was beyond probability.
