An ordinary boy, Ye Lin, accidentally picked up half a demon core and awakened to the middle-grade Xuan-level "Nine Nether Body Tempering Technique"! When the Bronze Realm monsters came to Jiangbei City, everyone ran away in despair, but he bucked the trend, fused the beast blood to break through the Body Tempering Realm, and killed the powerful enemy with one punch! The strong men of the Dragon Group looked at him sideways, the inheritance family secretly spied on it, and there was even a mysterious purple light hiding a shocking conspiracy. See how Ye Lin relies on the demon core and the "Hundred Herbs Classic" to speed up on the road of refining elixirs, casting medicines, and formations, sweeping through the nine major schools and the five major military academies, uncovering the ancient secrets behind the caves, and becoming the strongest man in the world of high martial arts!
