“Humans are like complex machines.”3

A human’s body is formed by the skin, nerves, muscles, skeleton, organs, and blood all intricately intertwining.0

So, with so many parts that formed the body, the question was: how should one handle this complex machine well?0

The answer to the question varied from person to person, and likewise, Se-Hoon’s answer was to focus on the blood aspect.0

“A human’s blood is fundamentally similar to fuel or lubricant, and with the advent of mana, it can also be used as a separate source of power.”0

Normally, people were only able to move their bodies through their nerves and muscles, however, when mana was introduced into the blood, people were able to move their muscles by controlling their blood instead of nerves.0

Of course, manipulating the complex muscle system using blood wasn’t easy, so one had to first fully understand their own body.0

“You can’t just let the blood within you flow freely. You have to be fully aware of where it’s going and how it’s moving throughout your body, just like how you are completely conscious of how you blink and breathe.”0

And during that learning process, one was required to consciously monitor tasks that usually happen unconsciously.0

Sharing his basic method of manipulating the body once again, Se-Hoon looked at Jake standing before him—or more precisely, at Jake, who was doing a handstand before him.0

“Ugh… agh…”0

Having been in a handstand for hours, Jake’s face was flushed red, one of his hands burrowed into the floor and tightly clenching the ground. Given his physical abilities, he should have been able to manage such a posture for ten hours under normal circumstances, but right now, the circumstances were anything but normal.1
