Usually, to even begin rebuilding the Energy Axis, it was necessary to spend a long period of time on energy control.
This led to Phantom learning to use his energy better and more efficiently, which meant that the pressure exerted on him by his own power became less.
If we compare this situation to a dam, Phantom was no longer afraid of the great flow and gradually opened one gate after another, carefully controlling the pressure.
However, there was another way to rebuild the Energy Axis—simply make it stronger.
If the flow of water were too powerful, the dam could be made much stronger if the necessary resources were available. If the electrical discharge was too strong, the wire could be made thicker, or a material with the least losses could be used.
It was quite difficult to do, but possible, because, as with every other aspect, to achieve this, the Phantoms had to go through a deadly, dangerous situation.
