Xuanhuan: This Technique Is Poisonous

Also known as: From Modifying Cultivation Techniques to Proving the Dao and Becoming Invincible “You want to die? You’ll die if you practice this technique!” Xu Ling’s father earnestly tries to talk him out of it, unaware that his son has the incredible ability to modify cultivation techniques. As long as Xu Ling kills evil spirits and gains energy, he can fix flaws in cultivation techniques and point them straight toward the Great Dao. From then on, he freely practices the techniques others dare not touch and takes on the evil spirits others dare not face. He is Xu Ling: son of a wealthy merchant, the Sky Observation Bureau’s strongest agent, scourge of evil spirits, cultivation-technique repairman, and the Great Dao’s new favorite.
