The Stele

Alex carefully observed and discovered that the mud was covered with a layer of green phosphorescence. 

Alex immediately understood that it must be the sap of some plant. 

He forcefully removed the mud. 

The mud was quickly discarded by Alex, and without wasting any time, he went straight into the cave and proceeded deeper inside. 

The further Alex went, the darker and damper it became around him. The air grew heavier and was mixed with the stench of decay. 

Alex shut off his sensory perception and advanced solely by smell. 

Suddenly, Alex stopped. 

He saw a stele standing ahead, with three characters inscribed on it: 

**Heavenly Silkworm Silk**

Alex stared at the inscription for a long time without looking away because he remembered that this was Mothman's favorite treasure. It could absorb the essence of heaven and earth, boosting one's power to the peak, even surpassing beasts of the same level.
