You have to say that the new power of his Slayer is already enough to kill any special-grade monsters without even using the origin spiritual energy.
Also using his new upgraded movement technique he could feel how fast he had become. Most likely right now even without using the concealment technique.
He already became a peak SS-grade Warrior, and it won't take that much time to reach the next Warrior grade. But before that, he also needed to find the limit breaker that would help him break through the barrier.
The thing was that after coming to this new world he was feeling that breaking through his hard became harder. Most likely it is related to the world he was in right now. Terraria was the strongest Warrior world. So it is natural that after coming to this Terraria he will face something like this.
