Teacher Lixia once told him that martial artists use the Core Secret Martial Arts to refine their physique beyond human limits, allowing their minds to sense and control the blood circulation in their bodies, accelerating it.
There are three nodes: the heart, the navel, and the Brow Chakra.
Each node that is opened can double the speed of blood acceleration and as a result, the speed at which power and strength explode in the same time. Casio had just broken through to where he could accelerate blood twice as fast, and now he could accelerate blood three times as fast!
Don't forget, at this moment, Casio's physique had already surpassed human limits. He could break an automobile apart with a single punch. And, this punch was three times more powerful! If he hit a human with such force, it would be like hitting a water-filled bag.
Bang!! It would explode instantly, its contents scattered like stars in the sky.
Casio could already envision the bloody scene.
