Zhou Qiaosheng traveled into an ancient city with only ruins left after 2000, and had Xiao Gu, a GPT assistant who could connect to modern archaeological data, in his mind. Every skeleton unearthed in the future will be a coordinate of death: three days later, the north gate was opened by a ghost, the underground grain depot of the garrison mansion caught fire, and the entire Baishi City was destroyed. Relying on modern urban planning knowledge and archaeological records, he rewrote the ending before the disaster time and time again. From the refugees who escaped from the living burial pit to the mastermind in charge of the city's defense; from guarding White Rock City to rebuilding the lost dynasty - this time, history must be as he wrote it.
