Because of this, to avoid disturbances to the High Tower from the outside world, the Guardians sealed the High Tower, completely isolating it from the outside. Therefore, even if outsiders wanted to invade or even occupy the High Tower, it would be impossible. Only a very few have been granted authorization to access the code to enter and exit the High Tower; others simply do not have this permission!
However, now someone has actually opened the door from the outside, and it's not even using their permission?
"What the heck is going on?"
"According to the report, the other party is using a high-level visitor permission. We've never seen this signal before. The data shows that the other party is from the Tribunal."
"What is the permission level?"
"Five Stars."
"What is this?"
"How could such a thing happen?"
