The protagonist is hit by a "sky thunder" and travels through time, but the sky thunder is actually an electric leakage accident caused by the failure of the ancient gods to cross the tribulation. Every time the protagonist tries to use modern knowledge to change history, the "Tiandao error correction mechanism" will be triggered - for example, when he creates gunpowder, Tiandao assigns him a stick overseer who can only recite "The Analects of Confucius"; he wants to start an industrial revolution, but Tiandao directly makes the water tanker grow legs and run away.
The protagonist has a "barrage system" - he can see the heads of historical figures floating over the real inner OS. When going to court, the ministers kowtowed and shouted "Long live the emperor". The barrage above their heads read "What time will this class get off work?" "I lost three taels in mahjong last night" and "I want to ask for leave because of my back pain."
