Stolen Spirit Root, I Rise with Waste Pills

Lu Chenzhou was once a genius rarely seen in a century in Xuanyang Sect, but during the Pill Sacrifice Ceremony, his master personally sealed his cultivation, and his senior brother cut out his Nine Yang Spirit Root and threw him into the Ten Thousand Poison Pill Pit to die. In desperation, he unexpectedly awakened the Myriad Tribulation Pill Furnace, discovering that all waste pills could evolve. Healing waste pills could mend broken meridians, toxic waste pills could be refined into poison meridians, and failed pills could even become lethal trump cards. While others fought over spirit pills, he specialized in collecting waste pills. While others relied on spirit roots to cultivate, he built his foundation with myriad pills and tempered his body with pill poison. When Lu Chenzhou returned to the sect, his former lofty enemies finally realized that what they had taken from him was never his future, but rather a death tribulation they had prepared for themselves. — Description from novelcodex.org
