I Am in the Demon Sect, and the System Forces Me to Be the Light of Righteousness?

Yun Yixuan traveled to a world of cultivating immortals, but what he awakened was a deceptive system called "The God of Righteous Studies". So what if the matching mechanism goes crazy? It's up to me to rectify this world of immortality! Magic skills? Modify the Vein running code and practice faster than a billion steps! Refining alchemy and refining weapons? Insight into the table of elements, the best spiritual treasure and elixir comes from the original idea! From improving basic exercises to creating self-made immortal magic formulas, from chemical synthesis and alchemy to new energy weapon refining. Is cultivating an immortal a matter of fighting and killing? It's human nature! Many years later, various inventions and patents in the world of immortality were all printed with one person's name: Yun Yixuan. "Have you heard? The new leader who unites the good and evil paths is actually the young sect leader of the evil path!" The sect leaders of the Righteous Path said: "Nonsense, our leader is from a well-known and decent sect!"
