Eric and the others waited a two days before getting their assignments again. He used this time to work with the others on training. Putting up his shadow wall for them to destroy. Due to his Radiation stat increasing most of them had trouble taking it down, Except for Brandon.
Most don't know his secret, but due to having double RP points he was a strong person. Eric and System had their suspicions that he also had double points in radiation stats as well. That would also explain how effective he was with his attacks.
Eric brought Acer to their training group. He was much more skilled in fight as the other, but couldn't take the shadow wall down. Eric decided to trust Acer now, until there was a reason to not trust him. He did give him a warning to keep a low profile due to unsettledness on the base.
