At the entrance of the valley, Luo Cheng found a covert place to dig a small hole, and buried a small alchemy pill. Replacing the dirt, Luo Cheng confirmed no one could tell he had done anything here and left.
This alchemy pill was called the Spirit Guide Pill. It wasn't to be consumed, but to be used as a marker.
Alchemy was a profession that went back to the distant past. It could be traced all the way to the very origin of cultivation. It was a broad and profound profession. There were alchemy pills whose grades were beyond a person's imagination, and the many effects and possibilities were as countless as the stars in the sky.
