Rebirth of the Useless Alchemist

In his previous life, he was an alchemy prodigy, but was betrayed by his closest kin, had his cultivation crippled, and was thrown into the Ten Thousand Demon Abyss. Reborn, he became the most infamous good-for-nothing in Qingyun Sect—every pill he refined exploded, and every spiritual herb he touched turned to ash. Everyone waited to see him make a fool of himself, until the entrance examination, where he refined three ancient demon pills in a single furnace. On the day the pills were completed, blood rain fell from the sky, and ten thousand demons howled in unison. "Who says a good-for-nothing can't refine pills? I'll refine every rare pill in the world, and there will be no pill in this cultivation world that I cannot create!" On the path of alchemy, I alone reign supreme. — Description from novelcodex.org
