"If the friction is severe and the contamination rate reaches more than 10%, then the inter-world rifts will become very frequent... In cases of severe inter-world friction, it's possible that the worlds could tear open 'rifts' which temporarily fuse together, causing a 'weak overlapping phenomenon'. During such times, the contamination rate can surge above 30%."
```
```
"After weak overlapping occurs, the physical laws and principles of the current region can change due to the overlap with the otherworld... There's also the possibility that creatures from the otherworld could come through the 'rifts' to our world."

Xue Jing suddenly said, "Is this the process by which Intersecting Boundaries are born?"

```
Void Blade shook his head, "Yes, and no."
