"Yes, the person who can go through that exclusive transport point needs your approval before they can cross over. This is also to prevent anyone from sneaking through and causing the world to collapse," confirmed the System with a nod.
"Has something like that happened before?" Xia Yue had watched some videos before that said behind every rule there was a bloody lesson.
"Yes, at the very beginning, there wasn't such a rule. But then the host's transport point got discovered by someone with bad intentions. That person sneaked into another world, a more ancient one whose development was not as advanced as the host's world. He brought a large amount of weapons with him, causing massive casualties and nearly destroyed a city's populace," the System explained.
Afterward, the host's system was forcibly disconnected. As compensation, everything the host acquired was taken back, their memory was wiped, and they returned to their original penniless state.
