Then Ike also found that all the defensive devices around the shelter had been destroyed.
Moreover, it seemed that they were destroyed by the last wave of beasts invasion. To repair these defensive devices, not only would it cost a lot of time and resources but even if it was repaired, it would be difficult to resist the next wave of beasts invasion.
That was why the residents of this shelter abandoned it and turned to other stronger shelters.
At present, similar situations could be seen everywhere in the world.
After Ike left this shelter, he met several other empty shelters along the way.
"It seems that such medium-sized shelters can't survive now. They can only rely on large shelters." Then, Ike opened the global list of shelters and found that there were only less than thirty thousand large shelters with the size of 2000 people left in the world.
