"Inside the cave mansion was a Space Channel, from which terrifying lightning power seeped out. Threadlike lightning power spread throughout the entire cave mansion, making the lightning energy within extremely dense. It was suitable for the growth of many kinds of medicinal herbs. With such pure energy, the herbs grew exceptionally well. If one entered again several hundred years later, I fear even Eighth-grade Alchemists capable of refining pills that produce Nine-Colored Pill Lightning would be envious of the herbs inside," Chen Huo said after carefully choosing his words.
