Each force unit was used to create a vibrating string within the empty space of the fourth layer. Combined with the 100,000 vibrating strings that he had before, he now had a total of 1 million vibrating strings.
When the 1 million strings became complete, the vibrating strings thickened. They doubled in thickness and became stronger.
He expected to become stronger because of this. After all, this was what had happened the previous three times since he upgraded the force organ.
However, what happened was that the force organ would go haywire. The force organ turned into a golden flame and began consuming his lifespan.
In an attempt not to die because of running out of lifespan, he consumed all of the world's essence in his possession. But this still wasn't enough, so he activated the Devouring Ability to consume the living things in his Cave Heaven.
