There was a group of alien cultivators guarding the entrance of the hole, and they were obviously stronger.
Their bodies were covered in black armor, like special keratin, which was probably formed after their skin mutated.
On the hard shell, there were all kinds of runes. Half of them were carved by rune Masters, and the other half were natural.
These runes formed a circuit that allowed energy to circulate freely without interruption at all times.
As they moved, a dull light would flow on the surface of their bodies. It looked very strange, making the foreign cultivators look like moving light.
The greatest function of the runic magic circle was not only to illuminate, but also to enhance one's own simulacrum.
Once it was attacked, the runic magic circle would automatically defend itself. The defense effect should be perfect.
