Sandhya
The commotion caused by the beasts and Sam was clearly noticed by the people in the city.
Many of the guards were dispatched to check what is happening. But to their surprise, no one was able to move past a certain distance from the city. All the merchants and travelers were also stopped. No one was able to move.
Even if someone strong managed to take a few steps forward, they felt like they are walking through mercury and their blood and bones have increased in weight by a couple of hundred times.
The city is effectively sealed in a way.
Of course, the strongest person is actually not of very high cultivation. They are barely two levels away from Sam's current cultivation. If he wants he could just kill the whole city very easily.
Unless the leaders of the clans can come down, there is no one who could make their way out of the spatial lock, and even if they can come, they wouldn't try to come.
