My Perfect Alchemy Rule

[The head of the Alchemy Immortal, the person who governs the Immortal Dynasty and is in charge of all knowledge] Zhong Cheng traveled through time and became a preparatory member of the Daxia Alchemy Division, and learned that tomorrow he would face a qualification examination that would determine whether he could embark on the path to immortality. Zhong Cheng, who does not know how to make elixirs, has awakened to an exclusive space that is guaranteed to make perfect elixirs. No knowledge of elixirs is required. It is fully automatic and easy to use. He can collect elixirs to unlock the world's prescriptions. After refining the elixir of longevity overnight, he attracted the attention of the Imperial Master and caused a stir among the senior officials of the Alchemy Department. Since then, he has been on a meteoric rise, ascending to the chief position that has been suspended for nearly a decade, refining elixirs, slaying dragons, controlling the court, and fighting the Immortal Emperor. Riding a crane to become a fairy starts with turning stone into gold!
