Theoretical physics doctoral student Lin Wan transmigrated into an immortal cultivation novel, becoming a cannon-fodder odd-job disciple. She was also bound to the "Strategy the Male Lead Home" system—getting the cold and proud sword cultivator Gu Changqing to say "I love you" three times allows her to return to her original world. Staying up all night, she drafted a "Feasibility Report on Honeytrap Tactics," calculated the strategy cycle using compound interest formulas, predicted demon cultivator attacks with probability theory, eliminated spirit aphids with wormwood powder, and blocked tribulation lightning with a Faraday cage. From selling a "Tribulation Lightning Early Warning System" to launching "Five Years of Simulation and Three Years of Immortal Cultivation," Gu Changqing was step-by-step "scientifically strategized" by her, achieving three confessions one after another. However, the moment the task was completed, she dragged the system into the recycle bin.
