Young Ye Xuan, originally a peerless genius of the Qingcheng Sword Sect, was secretly plotted by his hypocrite brother Li Wuya during the sect competition. His Dantian was shattered, he fell off a cliff, and became a useless person. When the family was wiped out, they were rescued by the mysterious killer organization "Blood Clothes Tower". As a result, they unexpectedly awakened the ancient metaphysical inheritance and obtained the "Nine Revolutions of Mysterious Heaven" and "The True Solution to the Alchemy Path", starting a counterattack. He disguised himself as a medicine slave and lurked in the Xueyi Tower, using metaphysics to improve the elixir recipe. He not only reshaped the Dantian, but also developed amazing strength.
In order to take revenge, Ye Xuan infiltrated into his enemy Li's family as a "waste son-in-law". During the day, he pretends to be stupid and uses alchemy skills to save people and hide his true strength; at night, he transforms into the terrifying "Blood-coated Judge" and kills his enemies. Relying on his incredible metaphysical deduction ability, he solved many unsolved cases, skillfully used pills to make friends with various forces, and gradually uncovered the shocking secret behind the family's destruction.
When Li Wuya colluded with the Demon Sect in an attempt to seize the Qingcheng Sword Sect's treasure, Ye Xuan stepped forward. He used metaphysical formations to trap the elders of the Demon Sect, used improved explosive pills to blow up the Demon Sect's stronghold, and finally killed Li Wuya with the "Nine Xuantian Swords" on the top of Qingcheng Mountain. He successfully revitalized the Qingcheng Sword Sect and became a legendary figure respected by everyone in the world for his "double skills of Dan and Sword".
