Global Power: SSS Level Doten God Thunder at the Beginning

A hundred years ago, monsters broke out on Blue Star and all countries fell. Humans begin to awaken their supernatural powers at the age of 15. Wang Jing'an, who traveled through time, had no suitable exercises for his awakened powers, and his cultivation progressed slowly, so he was unable to attend the martial arts university. Just when he was at a loss what to do, the system awakened, and SSS-level Duten God Thunder was fed to his mouth. Blue Star doesn't have a suitable technique? Don't panic, the system will bring in all the peak skills and techniques. "Origin of Qi Ti", "Nine-Character Mantra", "Five Thunder Methods", "Qi Men Dun Jia", "Golden Light Curse"... … Passerby A: "It takes other people more than ten years to practice a top-level skill. Why does Wang Jing'an act like he doesn't need to practice?" Passerby B: "Do you know how much psychological impact he will have on me if he hits me with his peak martial arts and SSS-level powers?" From then on, there was an unknown genius on the battlefield to resist monsters. With his SSS-level superpowers and countless peak martial arts and Taoist techniques, he killed the Human Emperor who was admired by thousands of people.
