He visited a larger practice room, where Immortal Servants were practicing, but they only provided the Pill Furnace, and the medicinal herbs were obtained by themselves!
From a distance, he watched them perform alchemy; actually, their alchemy skills were not very high!
Even though they were practicing Immortal Pills, their success rate was also low!
Jiang Tang had a confident thought that if he obtained Immortal Herbs here and used his Alchemy Furnace to create pills, the success rate might be better than theirs!
With this thought in mind, he wanted to find medicinal herbs in this castle, find herbs that could be used to refine Immortal Pills, and learn on-site!
He wanted to open each alchemy room one by one, but couldn't, so he could only observe the situation from the doorway, able to clearly see inside because of his ability, and because he was the owner of the castle!
Alchemists all have formations to prevent external causes from making the person refining the pills fail.
