Urban Cultivator, Watch Me Kill Gods with Physics

Earth, 35 years old, PhD in physics, Sudden Death Laboratory. When he opened his eyes again, he became a boy with the same name in the parallel world - 15-year-old Gu Ding, with mixed spiritual roots, D-level spiritual affinity, and ranked last in the school. My parents died in a car accident three years ago. I live alone in an old building in the old city and rely on a monthly subsidy of three hundred Ling coins from the government. No one remembers his name, and no one cares whether he survives the winter. It took him a while to accept the reality, and then he discovered that the efficiency of most of the immortal cultivation techniques in this world was between 20% and 50%. The top geniuses paired with the top skills can only reach the 60% or 70% threshold. Some people have been stuck at a bottleneck for three years, while others have been unable to make any progress their entire lives. And his knowledge of physics in his previous life told him: this is not metaphysics, this is a system that has not been optimized. Others rely on talent for cultivation, while he relies on formulas and derivation. He calculated that theoretically the efficiency could be pushed to more than 80%, or even close to 100%. He tried. And then it was. The elders of the sect said that he was deviant, but he said nothing and took out a piece of paper—— "This is the spirit particle density equation and energy path resonance model I derived. Please give me your advice." But right now, what is more important than subverting the world of immortality is—— The registration fee for the sect's entrance examination is five hundred spirit coins. He only had twenty-seven dollars left in his pocket.
