The capsule that was used in allowing Samuel and Thunder to be able to access the virtual reality was created by a technology that Samuel did not know about. Regardless, he felt that the kind of technology was just too advanced.
For some reason, he felt that the technology that was used in creating the capsule and the virtual reality were actually related. He was not sure about that, but he felt that the probability of that was high.
But Samuel did not have the chance of thinking that much about these issues, considering that just after the first monster had been killed, another one solidified.
Additionally, Samuel noticed one thing. It seemed that the recovery rate within this virtual reality world was almost the same as in the real world. Even though the eagle had not spent that much energy when it came to dealing with the monster, the energy spent was spent nonetheless.
