Three years ago, in Su Lin's eyes, Lin Yuan was merely an ordinary factory worker who could be ordered around at will. Three years later, he transformed into the chief expert of the national nuclear fusion project, hired as a distinguished professor at Linhua University with an annual salary of tens of millions. Su Lin eagerly wanted to follow this top expert to study, feeling quite smug, unaware that her lecturing professor was none other than Lin Yuan, whom she had once sneered at and looked down upon. Facing the harassment and slander from Su Lin and her rich-second-generation boyfriend Zhao Chen, Lin Yuan chose to endure quietly without arguing. When the Zhao family colluded with overseas forces, attempting to steal core nuclear fusion technology and secretly sabotage the experiment, Lin Yuan laid out a inescapable net, swearing to defend the country's vital equipment with his life, and making those with malicious intentions pay a heavy price.
