The group of people was rescued from that hell, where they were just waiting for their death. With limited water to drink and food to be eaten.
They all knew if no one were to come and rescue them, then their fate will be worse than before.
Where they could be killed in an instant at least by the fang of those monsters. As they all walked out of the elevator a sense of freedom overwhelmed their heart, while they form a strong determination to survive.
So, even children in their group along with their mothers sat silently without making any nuisance.
They knew that whatever they will get to eat and drink will be a miracle.
Aside from that, they carried the voice of their fathers, with those who truly developed the desire to survive.
This was looking good for all the members of the rescue team, but they still had to wait for 2 more people.
