Long Qingtian, the iron-blooded emperor of the Qian Dynasty, fell off a cliff during a palace incident and woke up in a completely unfamiliar world - a modern city in the 21st century. Not only did he lose his imperial power, he also became a low-level car repairman "Zhao Tiezhu" who was in debt and carried three oil bottles. From being a ninety-five-year-old to worrying about his livelihood, he must learn to touch the cold wrench and the hot life with a pair of hands that control the country. Let's take a look at how the emperor in trouble rebuilt the "land" in a place of chicken feathers, opened up a "new dynasty" in a car repair shop, used the skills of an emperor to deal with family conflicts and workplace crises, and finally found a world more precious than the throne in love and responsibility.
