I Built the Wind Spirit Root into an Engine

In his previous life, Lu Yichi stayed on the aero-engine test bench for ten years, measuring the pressure difference, flow rate and temperature rise. The test bench exploded three times, but he survived and all the data was recorded. After traveling through the third month, he was found to have wind spirit roots at the end of the Five Elements. The whole audience burst into laughter. But what he was staring at was not the grade, but the hair-thin wind pattern on the Ouija board - it didn't spread out, but chased around in circles, twisting into a steadily rotating vortex. "The weakest?" "Who has tested it?" He was assigned to Tingfeng Peak, which had not produced anything for forty years. There is only an old man who has been guarding the mountain for forty years, a broom, and a yard of fallen leaves that can never be swept away. Eighty-three days later, the sect was closed. If it fails to produce output, Tingfengfeng will be abolished. So Lu Yichi used two airflows to create a pressure difference, allowing the fallen leaves in the courtyard to line up and put them into the basket; he used bamboo tubes and animal skins to create a wind tunnel; he used a steady flow damper to increase the elixir production rate of the alchemy furnace from 30% to 50%. Produced by Tingfengfeng, the number is kept on file and the data can be checked. For three thousand years, everyone has regarded spiritual roots as water tanks and only measured the amount of spiritual power contained in them. But Lu Yichi knew—— Fenglinggen is not a water tank. It is an engine that has never fired.
