Reborn in 1999, I Set up a Stall Selling Dried Fish at the Beginning.

"Artificial intelligence + rebirth + cool writing + urban daily life + no super powers + no system + no immortality + technology + no brainlessness" Chen Tianqi, an artificial intelligence computer engineer, has been committed to exploring the frontier field of consciousness immortality, and is about to usher in a critical moment of success. However, what was unexpected was that his many patents, intellectual property rights, and outstanding research results that had not yet been published were greedily coveted by the upper echelons of Country M. In order to keep these valuable achievements of Chen Tianqi as their own, and to completely cut off the possibility of the research results returning to China, the upper management of country M did not hesitate to take extreme measures to maliciously sabotage Chen Tianqi's ultimate experiment, and arbitrarily closed and forcibly formatted the storage unit that stored Chen Tianqi's consciousness. But at this critical moment, Chen Tianqi's consciousness unexpectedly entered another parallel time and space. In this parallel time and space, his trajectory before the age of 16 was exactly the same as his original experience. However, because the time flow rate in each parallel time and space is different, the bifurcation of the parallel time and space trajectory at the age of 16 happened to intersect with the moment when Chen Tianqi's consciousness was expelled from another time and space. By such a coincidence, the consciousness of Chen Tianqi from the future magically entered the consciousness of Chen Tianqi in 1999, and the two overlapped with each other.
