I Sell Earth Goods in the World of Immortality

Shen Yan, 32 years old, was a former P7 of a large factory. On the day he was laid off, debt collection calls came to him along with his mother's hospital bills. He returned to the rental house and found a rusty door on the wall. Behind the door is another world - spiritual energy has been exhausted for three hundred years, salt is more valuable than life, and a pound of salt is exchanged for forty-eight low-grade spiritual stones. On earth, a pound of salt costs three and a half yuan. It takes half an hour on Earth and five hours over there. Others rely on their spiritual roots to achieve immortality, while he relies on modeling to achieve immortality. The rules are the interface documents, the arbitrage is the data structure, and the business between the two worlds is the distributed system. This is the story of an optimized programmer who causes trouble in the world of immortality.
