Chapitre 309: Tier six spell And Succubbus?

The footsteps of two people resounded in the empty mine as they slowly made their way deeper into the place. Illuminated by the light, everything was crystal clear in front of them.

Finally, after a long journey, they reached the end of the mine.

The rough patches of the mine were visible, and the mana here was very thin. If wizards used their power here, their spell power would decrease.

This was because all the mana in the surroundings was compressed into the mana crystals embedded in the walls.

There were two ways to create mana crystals: one was to slowly condense a wizard's mana using a complicated method, and the other was through natural formation in these mines, where the mana was compressed and naturally formed into crystals.

In this process, all the mana was absorbed into the crystals, causing the surrounding area to thin out. The older the mine, the more mana was compressed.
