I Became a Wasteland Martial Saint

Luo Sen lives in a wasteland world after the Great Ruin. It's rife with unknown viruses, deadly bacteria, and radiation powerful enough to destroy cells. There are feral ghouls, deathclaws, mutants... And there are laser guns, plasma cannons, power armor... He thought he would have to struggle to survive in the wasteland. Then a mysterious key appeared in a strange dream. It lets him transmigrate freely to a chaotic world of martial arts. Skin Tempering, Body Tempering, Sinew Transformation, Bone Strengthening, Organ Nurturing, Marrow Condensation... Perception Condensation, Spirit Stabilization, Sitting in Oblivion, Breath Stillness, Out-of-Body, Wandering Soul... He tempers the body through external martial arts and nurtures the soul within. And so, an extraordinary Martial Saint and Yang God arose in the cruel wasteland.
