Although not in the most conventional way, Adam was able to pass the first stage and rebuild the beginning of the Energy Axis. In percentage terms, it was about 15%, which was not bad, significantly better than before, but clearly not enough for Adam to return to his peak strength.
The Energy Axis was one of the reasons why the K4-Level was the longest for both the Phantoms and the Black Threat Level monsters.
Usually, at each level, there was one global obstacle that the Phantom had to overcome to move on, whether it was defeating the Beginning Monster, creating the First Key, the Two Walls, or the Crystal Gates.
At the K4-Level, it was the Path Construct, but it wasn't the only thing that made the Phantom stronger. If all previous methods restrained the Phantom's true power so that he would not harm himself, then the Path Construct and the Energy Axis were designed to make the Phantom as strong as possible.
