Rift Demons
"S-Senior Su…? How much do you know about that monster that nearly destroyed the Southern Continent — the Great Calamity?" Qin Liangyu asked him.
"That monster is a being that should exist only within the Dimension Rift — a Rift Demon. Rift Demons come in all shapes and sizes, there's not a single Rift Demon that looks exactly the same as another. The only thing similar about these Rift Demons are their strength. Because they are all born in the same harsh environment, they are all extremely tough and powerful."
"As for the Dimension Rift… it's basically a void-like place you must enter whenever you travel an extremely long distance from one place to another using teleportation, so there's a chance you might encounter a Rift Demon whenever you teleport somewhere very far."
"Of course, Rift Demons are not common encounters. In fact, they are very rare."
