I Traveled Through Time, and the Native Was Actually Myself

Maybe time travel is a good thing? At least Li Ming thinks so. But if there were many old-timers in the time-traveled world... The experience was extremely bad. Li Ming was planning to use modern knowledge to shock the natives of other worlds. But sadly I discovered: There is something wrong with this world! Not to mention that perfume, soap and gunpowder, which are killer weapons, have already been around. What's going on with this electric light and the smartphone that can start a group chat? What the hell is this furniture controlled entirely by smart terminals? And when I learned that all of this was done by the senior time traveler... Li Ming just wanted to ask: Have you ever respected the productivity of this era? When collective wisdom collides with individual power, the style of the world suddenly loses its steering wheel. And Li Ming was injured to the waist by the out-of-control dump truck. After the time traveler management organization, the Zhenming Division, caught him on the spot for smuggling. Then faced with a choice. It is to be a self-proclaimed protagonist and a time traveler who wants to change the world. Or join the Mingzhi Division who has absorbed the knowledge of time travelers and is even better than his predecessors. In a trance, Li Mingming realized the truth of the world. There are no stupid natives, some are just smart time travellers. So... A policeman from the Zhenming Division who appears to be an aborigine but is actually a time traveler walks around the world. And his goal is to arrest the world's travellers, and bring the world back on track. To achieve this goal, Still need... Become a native! ! !
