If the speed of physical growth were to exceed the speed of spiritual control, then the proportion of spiritual enhancement would decrease as well. And, if one were to expand this description, it would be as if ordinary people suddenly had the body of Superman, thus making it nearly impossible for them to adapt to Superman's body's strength for a period of time.

This was because, when one's strength suddenly increases, one is unable to adapt to the heightened strength, the control of the body naturally declines. Steve's physical condition undergoing the same struggles, at least in theory.

When he was practicing on the eighth level, his basic cell value would grow at an alarming rate and the strength would increase at a rapid pace. If his speed of brain development didn't keep up, his meticulous control of the body by his spiritual power would also decrease, just like in the sample principle above.

Naturally, the proportion of spiritual powers to strength would then also decrease. As it was 21% now, if the brain development didn't keep up, it might drop to 20% or even less!

"Is there a solution?" Steve asked immediately.

"In order for master's spiritual power and physical cells to grow in the most perfect way, it is recommended that master practice in the Original Gravity Tower for two hours every day. At the same time, he must also practice the 'Beginner's Way of Spiritual Training' for three hours," the Heart of the Universe answered.

Steve nodded. While practicing the "Intermediate Practices of Energy Absorption," he could also practice the "Beginner's Way of Spiritual Training." This was because the Fantasy Serum that he had taken could also be effective for both his physical and spiritual training!

The reason why he didn't use the seven-colored energy serum directly was that, according to the Heart of the Universe's a.n.a.lysis, taking it directly would be a huge waste. Thus, with Steve's current brain development, taking the Fantasy Serum to practice was enough.

Just like this, Steve gave up challenging. After all, he now had a basic cell value combat power of more than 370 points, and the eighth level s.p.a.ce checkpoint's magical beasts all had the strength of 370 points of combat power, so he no longer had the advantage in strength.

Moreover, he had no idea what kind of harsh environment the Original Gravity Tower would procure in the coming challenges! So, Steve chose to practice instead, steadily improving his strength first, and then he would continue to challenge later on.

*Gulp*

After drinking the Fantasy Serum, Steve began to practice the "Intermediate Practices of Energy Absorption," while his brain began to practice the ways of spiritual training.

The two modes of practices were carried out together. This way, the time required for each practice could be shortened. With a surge of cosmic force, the concentration of cosmic force around Steve's body was getting stronger and stronger, and his practices were getting faster and faster.

This time, Steve finally felt that his cells were greedily absorbing the cosmic forces and rising at a noticeable rate. As such, the pace of progress was much faster than before!

Steve went into a state of practice. The soldiers who were watching from outside for half an hour found that Steve had stayed on the eighth level and his state of practice had remained unchanged. They all heaved sighs of relief.

"He's stopped at last!" Audrey exclaimed.
