Zhang Jie worked as a hardware engineer for 3 years before switching to a software engineer and is now a programmer at a large factory. While on a business trip, he discovered that the startup time of the IBM laptop issued by the company was extended by 1.3 Seconds, and routine operations were not resolved. This aroused his interest. After several efforts on the high-speed rail to no avail, he forgot about it due to the arrival of the train and the business trips. One day while watching short videos at home, a time-lapse advertisement reminded him of the problem, and the character of "Axis" prompted him to try to solve it again. After solving the problem of boot time, check the computer log before shutting down to let him open up a new world. He found that the data in the log had traces of being "swallowed", similar to human CT calcification lesions, and the changes only occurred in the shutdown state. There were traces of "escape", "displacement" and "merging" in the log code. He was not sleepy at all, and felt that there was a strange and friendly data stream staring at him. Zhang Jie continued to read the diary, mobilized all his knowledge reserves, studied like an archaeologist, and discovered the digital shadow. The extracted samples will be analyzed by various software and the results will be negative, which is impossible in reality. In his sleep, he played back the changes in his diary. The dream was like a documentary about ancient evolution, and no one could share it after he woke up. Since then, apart from work, Zhang Jie spent time in libraries and cafes trying to find ways to explain. While searching for information, he accidentally saw the bookshelf of anthropology and sociology, and he suddenly realized that dreams might be a guide: the changes in the computer are like the evolution of early life forms. These life forms do not require oxygen and water, and their metabolism and energy cannot be described and explained by current knowledge. However, it is observed that they borrow money to maintain integrity and balance. This kind of borrowing behavior seems to only appear in advanced civilizations...
