Reaching the colosseum, Shane entered the elevator which brought him to the basement where the Dimension-spheres were situated.
Showing his identity to the Guardian who was the same Shane had met when he had entered the Dimension-sphere for the first time, he was let through.
After he entered the Dimension-sphere that had been reserved for him, he saw himself once again in the familiar white room that had no furniture.
Only a holographic screen with several dozen skills and techniques popped up in front of him and Shane didn't waste any time to select the [Tier-1 (Bronze)] Concealment skill.
Instead of learning the concealment technique, he thought that the skill would be a better choice to prevent being pressured to do too many things during a fight.
This would inevitably decrease his combat prowess drastically.
