In the deep winter of the third year of Chongning, under the remaining wall at the west corner of Xiangguo Temple in Bianjing, Chen Yan suddenly opened his eyes in the biting cold wind. One second, he was a delivery rider taking shelter from a truck on a rainy night in 2023, and the next second, a thin, cold body was beating in his chest - the original owner was a refugee whose parents both died. He fainted from starvation and failed to wake up on the street, which gave him a place for his soul after a thousand years. There was only half a piece of hard wheat cake in his arms, and he was as hungry as a knife. The fragmentary memories of the original owner told him: Under the prosperity of Bianjing, it was common for refugees to freeze to death and starve to death. If they wanted to live, they must find a livelihood immediately.
