Wu Pifu stood unharmed amid the invisible attack, lost in thought.
For now, it seemed the special supernatural powers in this world fell into two categories.
One was the conventional manifestation of power he was familiar with—strength, speed, attack power, attack range, and so on. It was no different from him or the other enemies he had encountered. You attacked, they attacked; people died when killed. Their overall strength broadly matched this rule, except their inexplicably swollen vitality had multiplied it several times over.
The other was a completely invisible special attack that could not be observed or even sensed. It possessed an irresistible quality. Even with his current strength, he could not withstand it head-on. If he was hit, he might very well be killed instantly.
That attack just now, which had compressed everything within three hundred meters into a cube—if he had not used Superbrain World to strike the invisible barrier hundreds of times in succession, shatter it, and escape, he might have died inside it too... at the very least, his body would have died.
The old man's power now belonged to the first, conventional category. It had merely been amplified and strengthened for some unknown reason... but that was all.
There was an entire dimension of difference between their strengths. By conventional standards, let alone these twenty-some people, not even twenty thousand beings of the same level could have harmed so much as a hair on his head.
"...The key is the second type of attack. This must be the supernatural manifestation in the domain of souls and true spirits that Beelzebub mentioned."
By then, Wu Pifu had already flown tens of thousands of meters, smashing through two small peaks. He let out a thunderous roar in midair, and the immense force crushing him instantly collapsed.
