The demonic teleportation portal was surrounded by a vast expanse of open territory. They did not dare to get near, could only hide behind black giant rock hundreds of meters away from the portal, looking for the chance to get past.
"That's the teleportation portal," Y'zaks took this opportunity to share the knowledge of this world with them, "in this world, at least within the already ascertained world, space vesicles are the only form of space, and each space vesicle will have more than one natural channel connected to other spaces, just like this one. This kind of portal is the most important military hub in every space and will be heavily guarded by the rulers of each space. Of course, these are limited to natural portals, the randomness of artificial teleportation portal is too strong, and usually unstable, can only last for a short period of time."
