Fang Yuan, a 37-year-old programmer, was trapped in the most chaotic day before the project went online. When he woke up from indulgence and despair, he found that he had gained a strange ability: every time the cycle restarted, he could randomly glimpse a fragment of the true destiny of the future. He saw that he died suddenly, the company exploded, and his family was broken... All these "program bugs" will run as scheduled tomorrow. Now, he holds the incomplete "precognition log" in his hand and is in this infinitely reset "debugging sandbox". He must use the thinking of a programmer to find the only way to pass the level in the 24-hour cycle for his family, career, and himself who is stuck in the quagmire of middle age. When the clock strikes midnight again, can he submit the final patch so that the tragic version will never be updated?
