On the day he was expelled from the sect, Luo Chen's spiritual roots were shattered and his Dantian was cracked. Everyone said he would die in the Desolate Valley. When the fragments of Heavenly Dao smashed into his wound, he curled up in pain - this was not a golden finger, but a torture instrument. But he survived. Open a medicine shop in a wasteland filled with poisonous fog, plant spiritual herbs from the ancient books of Kyushu, and use the ability to sense the pain of others to heal casual cultivators. "Return" gradually became the only light in the Desolate Valley. But light attracts moths: Tianyan Sect discovered that he could refine forbidden elixirs, the Divine Dynasty was eyeing the fragments of Heavenly Dao in his possession, and the Demon King of Ten Thousand Demon Ridge wanted to refine him into a human medicine cauldron. Yin Xiaotang blocked the fatal blow for him, and after Cang Xuanji's self-destruction, Situ Hongxue knelt down and begged him to give up the medicine shop. Luo Wan wiped the blood from the corner of his mouth, broke the broken bones back into place one by one, and said with a smile: "The thing I am least afraid of in my life is pain." The enemy will never understand why a person who lives in hell every second can still hold the medicine hoe tightly. Until they saw Luo Wan dragging his broken body, using the slowest footwork and the stupidest tactics, forcing them into a desperate situation inch by inch. God wanted him to be in pain, so he used the pain as fuel.
