Erik left the underground shelter and turned invisible.
The last thing he needed was for the monsters to know where the base was located—revealing its position would compromise not only his safety but also endanger any future operations he planned to conduct from there.
His mission was to find and analyze some thaids. He had two crucial reasons: first, to determine if he could survive in this environment, and second, to assess whether Amber and the others could have survived here as well.
If the thaids were too strong, he and the others would just die in a direct confrontation. The only way for Erik to survive would be to stay holed up in the underground base, train, and make Chimaeric Demons. It would force Erik to completely change the tactics he and the clone would need to use to fight the monsters.
[You're worried more about their research than them searching for my blueprints,] the system said. [Pretty insensitive.]
