Werther sat cross-legged in the quiet Bedroom.
Bright sunlight slipped through a gap in the curtains, drawing a golden line that seemed to divide the Bedroom neatly in two.
When he saw the 520,000 points of Life Force, Werther could not help smiling.
Most of it had probably come from that colossal Sea King.
Yet even after losing so much Life Force, the colossal Sea King was still full of energy.
It showed just how much Life Force those enormous creatures held within them.
If he ever absorbed Zunesha's Life Force, he would gain at least a million points.
Werther tapped a finger against his forehead and considered which ability to strengthen.
Thunder Core? Werther shook his head, ruling it out first.
The 520,000-plus points of Life Force would be enough to raise Thunder Core by one level, but it would not be worth the cost.
Werther planned to eat all the Vitality Crystals first, then use the resulting million-plus points of Life Force to strengthen Thunder Core.
He ruled out his two forms of Color Haki as well. Both were already highly developed, and he had strengthened them recently. He needed time to consolidate his gains.
If he raised his Color Haki too quickly, his body would struggle to adapt. The last time he had raised his Observation Haki by four levels at once, it had suddenly gone out of control. That had been dangerous.
As for Hand-to-Hand Combat, Werther had even less interest in strengthening it. Swordsmanship, Haki, and lightning were the core of his fighting style.
It might sound like a scattered combination, but his Haki and lightning both served his Swordsmanship. Werther was a swordsman: Swordsmanship took the lead in battle, while lightning mainly supported it.
That left speed and Physical Strength as his best choices.
