Beast Horde
Elder Huan also explained other rules. Everyone from the Godly Tower is free to roam outside, but they can't abuse their power. The Godly Tower is a neutral power that must not ally with any of the other groups. That's because in case they do that, the other forces might rally together to attack the tower. That is not what everyone wants. Once you enter the tower, you are also relinquishing all power connections with your last background.
Of course, you can still visit your family and interact with others. But you must absolutely not take any sides. At most, you might intervene to save your family if they are at the brink of extinction, but you are still not allowed to change the results that led to that. Otherwise, you will be expelled from the tower, and your cultivation will be destroyed. Thanks to that, all hundreds of small powers in the city had never touched the tower.
