Astrid had come to visit them on the first day after the blizzard ended after Treyton and the others had cleaned the road.
Astrid came alone and went to talk to her friends, but Calvin didn't come.
So, it seemed that he was still in the research institute like his uncle.
Treyton had already mentioned that most of the time his uncle would just spend his time in the research center dormitories and rarely go home.
Treyton hadn't seen his Uncle Lawrence again since the day they came, so Treyton had wanted to visit him at the research institute to know what his uncle and the others had found out about the apocalypse.
Luciel was also curious about what they had discovered at this stage. He also wanted to see what they are currently researching.
So, he decided to follow Treyton and go with him to the research institute.
The research institute was just beside the military base.
When they reached the institute, they were led by the guard outside to the office of Treyton's uncle.
