Lin Fei traveled through ancient parallel time and space with his AI mobile phone, but failed to possess emperors and generals. Instead, he became a fugitive in an instant and was on the run. Fortunately, in ancient times, AI was simply unparalleled, omniscient and omnipotent. It could always generate wisdom in critical moments and help Lin Fei resolve dangers. It could even construct a primitive industrial system and arrange for subsequent system upgrades, defeat the imperial court, pacify the barbarians, create unification of the world, usher in a peaceful and prosperous era, and promote Chinese civilization.
