The barbarians didn't take the truce agreement from Sam lightly. And they took the attack on the city harder.
They didn't know if Sam could really do it a hundred times more, but they know one thing, they have to deal with him as fast as they can, so they moved the whole city's population to the estate, the estate is cramped and even though it occupies one-fifth of the city, the whole population is still a bit overwhelming.
The weakest of them all are sent directly into their underground temple which is the safest space of all and then they started placing the people in increasing order and the Consummate level people are almost in open grounds of the estate.
The Astral Plane cultivators are having the lowest level of protection.
