When Noah was inside the dark world, he had the power to defeat an entire army of rank 7 cultivators that contained five experts at his level.
That battle prowess was absurd for an existence who had just advanced to the liquid stage, but Noah wasn't an ordinary cultivator. His new power also came from the Great Builder's inheritance, so it wasn't a surprise that he could express such strength.
However, every ability had weaknesses. The workshop was an incredible technique, but its creations were valuable only when Noah used them to overwhelm his opponents. In a situation when everyone was doing their best to run away, the dragons couldn't express their real power.
Noah used his movement technique to reach his target in an instant. Chief Barret soon appeared in his vision, but Noah only saw a blur as he flew through his body.
