I recommend the fantasy novel " Longevity of Martial Arts: Starting from the Cultivation of Vajra Arts " to you. The main character, Xia Wuji, had transmigrated to the Immortal World. Because he did not have a spiritual root, he was not fated to enter the Immortal Dao. He could only cultivate mortal martial arts, including the Indestructible Body of Vajra. Xia Wuji had practiced the Indestructible Body of Vajra, the Dragonesque Elephant Heaven Suppression Technique, and the Nine Dragons Flying Skill into the Heavenly Dragon Combat Body. He had also practiced the mortal martial arts, Ferocious Tiger Fist, to the 3000th level, and he had powerful moves such as the Immortal Slaying Sword and the Demon King Explosion Fist. I hope you like my recommendation.
