Hai Yan's novel was "Intelligent Time Travel". The plot was that the launch of the intelligent time travel system marked the peak of China's technology industry. It was a method of decomposing the human body from quantum particles into neutrons and transmitting the human body to different dynasties and the future, realizing the true meaning of transmigration! Please take a look at the tragic and happy life that the protagonist Zhang Dali encountered when he traveled back to ancient times and the Five Worlds. I hope you like this fairy's recommendation.
