The gem seal coated the crystal wall with a layer of protective film.
Not only could this protective film block out probes from other planes, but it could also make it difficult for planar teleportation spells to cross the crystal wall of the plane.
Currently, only garen and the living beings that he allowed could freely teleport across the crystal wall.
"Phew ..."
Garen let out a long breath.
The gem sealing technique was equivalent to putting an anti-theft door and a security lock on the lava half-plane. In the future, there would no longer be any random plane transmigrators entering at will. This way, this place would truly become garen's private territory, and he would be the only Lord here.
After setting up the gem sealing technique and solving a problem that had been bothering garen for a long time, he was distressed because of the loss of a large number of gems. On the other hand, he felt a lot more relaxed because of the safety of the lava half-plane.
