If a Nuclear Explosion Occurs, I Only Need to Eat a Steamed Bun

[Starting from the early stage of martial arts + disease mutation + handling of mutation events + revenge + nuclear-level self-destruction at the beginning + brothers are beautiful girls] Cheng Du's digestive system disease is the Guixu engine, which can achieve E=mc², infinite mana, but has no skills. Fortunately, he has a killing card explosion system! He joined the official organization and dealt with the disease incident, killing the diseased mutants to gain skills, while taking revenge on the villain organization that forced him into a nuclear explosion and destroyed a city. Chapters 5 to 10 are a little slower paced, but interesting.
