Elder Pear

About two meters above, Lin Mu saw that there were several cracks in the tree trunk. 

The sap was leaking from these cracks and had even solidified around some of the cracks. It looked like a layer of glass coating the trunk once it solidified, which made Lin Mu realize why he hadn't spotted them earlier. With how transparent they were, it just looked like the trunk was there.

~Crack~

Lin Mu rubbed the drop of sap that had hardened on his hand and made it crack.

"It's still fragile in this state, isn't it?" Lin Mu asked.

"Yes, it needs to be further processed." Shuijing Mingzhu replied. "In its current state, it is only useful in making some formation ink that is specialized for light elemental formations or talismans." She added.

"Light Elemental ones?" Lin Mu raised his brows before realizing this was due to the natural affinity of the sap.
