Using Physics to Defeat the World of Immortality

At the age of thirty-six, Gu Huanyu, a physicist at the National Laboratory, collapsed on the eve of his thesis defense. When he opened his eyes again, he became the most prodigal son in Jiangning City - his father, whose spiritual roots were shattered, had just died. The land deed of his ancestral home was surrendered to a gambling house, and the medical center was only an empty shell. Behind him, he still had thirty acres of thin farmland and three hundred taels of bad debt left by the Yueguang clan. The good news is: there are cultivators in this world. The bad news is: he's not. But he is engaged in physics. --- The first disciple of the Qingyun Sect's Qi Xiu Pavilion was trapped in a bottleneck for three years. He handed over a cold and heat watch: "The furnace temperature is measured as a number, not a feeling." Su Yijun took the quartz tube filled with mercury and knew for the first time—— It turns out that mortal eyes can also see things in her world that have never been named. --- Later, someone asked Gu Huanyu: You are a mortal, how can you stand in the Qingyun Sect? He didn't answer. He only remembered the first question: Yijun gave you the silver fern on credit, what did you exchange for it? He was silent for a long time. "I haven't paid it back yet," he said. "I'll wait until I think about what to pay back." He didn't know how to pay it back. --- Later, news came out from Qixiu Pavilion: Su Yijun made a breakthrough. She drew the temperature curve of the high-grade magical instrument on the furnace three years ago and posted it on the wall of the refining room. There is a line of words below the curve: "On the thirty-seventh breath, add a piece of red copper. The temperature of the furnace suddenly rises to 80 degrees." That was the first question Gu Huanyu asked her. She remembered it for three years. --- This is the story of a doctor of physics who traveled to the world of immortality. There is no spiritual root, no skill, and no sword to open the heavenly gate. All he had was the second law of thermodynamics, a foundation in materials science, and all the sincerity a guy who'd never chased a girl could ask for.
