As Ye Chen moved forward, he encountered a door that was tightly shut.
Next to the door lay a demon corpse that was already deceased. Only its bones remained.
In its bony hand, there was a sheepskin scroll. Ye Chen approached and took the sheepskin scroll to examine it.
He observed that there were no words written on it, just a picture.
The image depicted a large alchemy furnace, with two elder figures who appeared wise, seemingly engaged in the process of refining pills.
Aside from that, there was nothing more to see.
Ye Chen pushed open the door and entered with Mu Yan. Inside, they discovered ten corpses surrounding them.
The corpses were arranged in an orderly fashion, their hands resting over their chests.
Upon closer inspection, Ye Chen noticed a black bead within the mouth of each corpse.
The bead was crystal clear, and after all these years, it still shimmered with a radiant glow.
