After Time Travel, I Had the Power to Put Out Fires in Ancient Times.

The protagonist is a firefighter who sacrifices his life and travels back to ancient times. Just when I opened my eyes, my dear, the beams were falling, and a whole room of people were crying for their fathers and mothers. With twenty years of professional instinct, he rushed in to save people without saying a word - he tied knots with sheets and relied on experience to judge how long the beams would last. He saved eight lives in one operation. Then he discovered that there was no fire brigade in this dynasty! A fire can burn down half a street. Some people use fire to make money, while others use fire to put out people's lives. What to do? Build it yourself! Improving water dragons, training team members, designing demolition tools, setting up fire prevention zones... Others traveled across time to compete for power and profit, but he traveled across time to put out fires every day. As a result, he saved and saved, and he became an official of the imperial court, and became a confidant of the emperor, and finally he lost all his power in the government. The key is that his promotion relies solely on professional ability, and every fire is a dimensionality reduction blow. The villain wanted to burn him to death, but he was caught in the fire with his backhand. It's really cool!
