Devil Instructor: 100 Days of Military Training for a Star

To rectify the entertainment industry, the hardcore military reality show "Iron Will" premieres, featuring four controversial stars undergoing 100 days of grueling training. Retired special forces operative Qin Feng (codenamed "Shura") is appointed head instructor. He accidentally binds with a "Positive Energy System," gaining points for training stars which he uses to upgrade his abilities. The four guests: Su Weiyang, a slandered pure actress; Song Ya, a gold-digging socialite; Xie Qian, a spineless "black-red" star; and Zhao Cheng, an arrogant corporate-backed celebrity. Qin Feng imposes iron discipline immediately. He accumulates points, enhancing his senses and physical strength to superhuman levels. During a field drill, they encounter bank robbers. Terrified, Xie Qian pushes Su Weiyang toward them. Qin Feng momentarily compromises to secure her safety, but strikes decisively the moment the robbers let their guard down, successfully rescuing her!
