The Supreme One

But before taking the next step, Xia Xian still had to review the "Basic Knowledge System of the Human Body".

This was naturally no longer simply relying on his own brain power, but after being well prepared and placing a large bottle of brain-tonifying liquid in front of him, Xia Xian immediately merged with the spirit of the Endless Book, and his brain power instantly doubled.

While drinking the brain-boosting liquid as usual, I started from the beginning and constantly reviewed all the knowledge in the "Basic Knowledge System of the Human Body".

The previous feeling of simultaneous thoughts before and after came back.

Xia Xian couldn't help but immerse himself in the thrill of racing his brain.

Soon, he reviewed the entire knowledge system again. Almost all the nodes that had not been thought of or solved before were solved, and some details even gave rise to a large number of detailed knowledge contexts.

In the knowledge space, there were originally two separate human body models, one with clear bones and muscles, but the brain was empty.

One is that only the brain and the peripheral nervous system exist, and the rest is as illusory as clouds and mist, but it seems to have really constructed a complete human body. The light spots in the entire network change, as if there is really someone thinking.

Now, the two human models gradually approached each other and then completely merged into each other.

The whole body seemed to come alive, and the illusory, tightly closed eyes slowly opened, looking at everything around them with a lively look.

At this moment, the endless book in Xia Xian's mind also shook violently, and the knowledge space in it expanded rapidly.

The space that originally seemed somewhat illusory now seems to be completely solid.

However, it is not like the ordinary world with clear sky and earth and deserted avenues. Instead, it is like a huge giant, breathing and growing slowly.

The breathing of this world is imperceptible to ordinary people, but they can see the surrounding unsolidified virtual space shrinking and expanding, as if it were really breathing.

But the breath was not ordinary breath, but the spiritual power between heaven and earth.

Even though this endless book is still stored in Xia Xian’s brain, it can no longer stop him from breathing the spiritual power between heaven and earth.

Even the owner of the library on the rooftop could not detect the absorption of the spiritual power of heaven and earth by the Endless Book in Xia Xian's brain.

It was as if there really was an incomparably huge giant, standing illusory between heaven and earth. With every breath he took, the spiritual power of the entire world disappeared for no reason, and then appeared in the Endless Book.

Of course, this so-called immense size also has its limits. If Bai Mulin completely releases his spiritual consciousness and observes carefully, he can also find that the spiritual power has disappeared a little bit in the surrounding space of ten thousand meters.

When the surrounding spiritual energy replenishes it evenly again, it takes another breath to absorb this part of spiritual energy again.

Yes, when the entire "Basic Knowledge System of the Human Body" appeared in the Endless Book in its entirety, the knowledge space within the entire Endless Book had expanded to a size of ten thousand meters in radius.

And in this endless book, a seed-like ball of light was flickering faintly, and the inside was completely filled with light.

It was just that in the breathing of this Endless Book, the light in the seed also flickered with the breathing, then gradually converged, and finally slowly remained in its core.

But even though it only occupies one-tenth of the space, the light emitted by this ball of light is still so dazzling that at just one glance it is as if one is seeing a person's life.

From birth, to existence, and finally to loss.

The brilliance of every moment in a person's life is condensed into one, and it becomes this dazzling light.

However, neither Xia Xian nor the Book Spirit noticed any changes in the Book of Endlessness.

At this time, Xia Xian had already gone through the entire knowledge system, but he did not expect that an extremely tall figure seemed to appear in front of him at some point.

But it seemed as if this figure had always existed in front of him, but he had never discovered it before.

Even now, he couldn't see her full appearance. He could only see those eyes full of tenderness.

There seemed to be some words contained in these eyes, waiting for Xia Xian to interpret.

But just seeing these eyes occupied Xia Xian's entire mind, and he was unable to think about anything else.

In the end, there was only a look full of approval left in Xia Xian's mind, and it seemed to carry a hint of expectation.

But when Xia Xian focused his mind back on his body, he was shocked to find that he seemed to be able to see everything inside his body!

As long as he wanted, he could see his muscles, his bones, his internal organs, and even let his vision follow the cells in his blood vessels as they moved back and forth throughout his body.

No, that's not right, it's more than that!

Xia Xian just moved his mind, and those parts that were clearly outside the nervous system and beyond the control of the muscles began to change at will according to his thoughts.

Not only that, he can even control the red blood cells in his blood vessels to flow upstream!

This unimaginable extreme control made Xia Xian feel as if his blood was boiling.

It seemed like, as long as he wanted, he could control his blood to boil!

At this moment, his brain, which was running at full speed, suddenly had a flash of inspiration and thought of something that happened a long time ago.

The very next morning after he created the "4.0 Version of Physical Fitness Technique", he felt that his control over his body had improved unreasonably.

Looking back now, this was probably a reward from heaven, but I didn’t realize it at the time.

As for the current level of control over his physical body, Xia Xian felt it and thought that if he said it was useful, it was indeed useful, but if he said it was useless, it was not very useful either.

Even if he exploded his physical strength to the extreme, and risked his life to unleash ten or a hundred times the strength, it actually didn't make much sense.

This is the world of cultivators. People practice, use spiritual power, and even directly use explosive spiritual techniques to easily unleash even more powerful power.

The greatest benefit to Xia Xian should be the ability to obtain more accurate physical data.

This should be a good auxiliary effect for his research on new version of physical fitness technique.

However, before Xia Xian could think about it any further, he clearly felt his brain sounding an alarm and his brain energy was about to be consumed to the dangerous line again.

It’s a pity that even with Xia Xian’s current control over his body, he has no better way to absorb elixirs.

The more he knew, the less Xia Xian could use the control over his body at will.

Of course, he could increase his body's digestive capacity ten or a hundred times. With the knowledge he possessed and the control over his body, he could indeed do so.

But the body is a whole, and what he needs is a longer-term future!

If you destroy the balance of your body in order to become strong temporarily, you will need to spend more time to adjust back in the future.

Moreover, this kind of physical imbalance can only be adjusted by oneself, and healing magic will not be of any effect.

Therefore, it can only be used to play some auxiliary effects.

When Xia Xian separated from the book spirit, the book spirit immediately noticed the changes in the book.

After telling Xia Xian everything, Xia Xian couldn't help but fall into deep thought.

This complete "Basic Knowledge System of the Human Body" is probably something that the Heavenly Dao can appreciate, so it gave them such a great gift.

It’s just that the Heavenly Dao didn’t know what was already in Xia Xian’s head, but instead needed him to write it down and put it in the book before the Heavenly Dao could react.

Does Heaven respect human rights or something?

Naturally, there is no answer to this question now, so Xia Xian put it aside for the time being.

At least the feedback given by Tiandao is equivalent to authoritative certification on the other hand, which means that the knowledge system he has researched is indeed true and effective, and there should be no problems.

In this way, Xia Xian felt relieved and continued his research work with peace of mind.

Although this physical fitness exercise generally incorporates brain training and strengthening parts, and is bound to be much more difficult than the "Physical Fitness Exercise 4.0 Version", it will undoubtedly be much simpler based on the "Basic Knowledge System of the Human Body".

In addition to previous experience and sufficient understanding of the linkage between the human brain and body, Xia Xian estimated that it would take less than half a year, or three months at most to complete.

What Xia Xian didn't expect was that his research process was not as peaceful as before.

Just a few days after Xia Xian started studying the complete "Knowledge System of Exercise Strengthening during the Human Body Strengthening Period", the end-of-year school assessment arrived.

Xia Xian almost overlooked this fact. Even when completing daily training tasks on weekdays, it was no longer necessary to occupy all of his brain power.

Even when you have mastered it completely, you don't need to use even 0.1% of your brain power. Except when you sleep, your brain is basically thinking and deducing difficult knowledge problems every moment.

On this day, Xia Xian came to the school, had breakfast as usual, and then walked slowly to the training ground.

Sheng Wuya, who was eating breakfast and seemed a little excited, had not noticed Xia Xian's deviation. He walked towards the physical fitness test classroom next to the training ground like everyone else.

After swallowing the breakfast in his mouth, he was about to speak to the person beside him: "Hey, Xianzi, guess..."

When he turned his head, he suddenly realized that Xia Xian had gone to the training ground at some point, and he immediately looked helpless.

He took two steps forward, grabbed Xia Xian's arm and pulled him back to the right direction.

"Old Xia! Come back to your senses! Today is the end of the year and we have to take the assessment."

When Xia Xian heard this, it was as if a switch in his brain was triggered. His originally scattered gaze became focused again, and in the blink of an eye, it was filled with a gleam of inspiration that seemed to be about to overflow.

When looking at Sheng Wuya standing aside, he felt as if he was pierced by the invisible light in his eyes, and everything about him seemed to be exposed in front of him.

Sheng Wuya's heart also trembled violently, but because they had been together for a long time, he was used to his gaze, and he quickly raised his hand to turn his head away.

Even though he was used to it, he still found it a little unbearable to be stared at all the time.

"How are you? Are you back to your senses? Guess how well I did in this test?"

"How good can it be? The full score in the academy is 6.0. Even if we improve it even more this year, it will still be more than 6.0, right?"

While answering Sheng Wuya's questions, Xia Xian also looked at the students around him.

There is no need to use any testing beads. Xia Xian can tell the level of these people just by using his naked eyes.

With his understanding of the human body, these people's skin and muscles could not hide any secrets from him.

But it seemed to be just like that, the classmates who had originally had a relatively harmonious relationship with him, now saw him looking at them, and avoided him like the plague.

Invisibly, a three-meter-wide hole appeared around him. This reaction made him confused for a while and he didn't know what was going on.

But there are also brave people who can withstand his gaze that seems to be dissecting them and come to his side with strength.

"Xia Xian! Be careful this time. I am no longer the same person I was a year ago. I will definitely make you pay this time!"

"Oh, no, thank you, I look good enough." Xia Xian joked with a smile and looked at Meng Hu beside him.

The two younger brothers who usually followed him were now hiding in the crowd. Even with the big brother in front of them bearing the pressure, they did not dare to take a single step forward.

Hearing Xia Xian's joking words, Meng Hu snorted in dissatisfaction, clenched his fists, and actually made a crisp sound of breaking through the air.

This couldn't help but arouse some interest in Sheng Wuya on the other side. He looked curiously at Meng Hu's palms, which had obviously become much rougher.

"Wow, you're practicing Tiger Claws so early? Is it necessary?"

Although Sheng Wuya had never actually seen the inheritance of the three-way tiger claw technique of their Demon Tiger Training Hall, he had heard about it roughly.

Now looking at the appearance of Meng Hu's hands, he immediately associated them with the tiger claws that the elders in his family had talked about.

The fact that a physical skill inheritance can even have a place in the eyes of the Saint Family shows that it must be very strong.

Seeing that no one knew Sheng Wuya, Xia Xian gave him a puzzled look.

Although he had some fragments of the Demon Tiger Cultivation Institute's inheritance in his mind, they were just fragments and not very useful.

Sheng Wuya also thought about it carefully before explaining: "I remember my family said that obtaining the essence of the magic tiger clan's claw attack and the secret of refining claws can help improve the adaptability of the magic tiger clan's bloodline and enhance the refining effect of the magic tiger clan's bloodline."

Listening to Sheng Wuya's words, Meng Hu proudly raised his hands and waved his fingers like tiger claws to show off.

But after a two-second pause, Sheng Wuya gave the final comment from his elders: "It's a little interesting, but not much!"

This made Meng Hu's hands stiffen. He quietly put his hands down and looked at Sheng Wuya. Although there was dissatisfaction in his eyes, he was helpless.

There was no way. If anyone else said this, he would have to go up and argue with them, but it was the Holy Family, who were not at the same level as them, so it was not surprising that they made such a comment.

Not angry, not angry.

He suppressed his dissatisfaction and decided not to give face to the Holy Family in the next battle. After teaching him a lesson, he calmed down.

Then he looked at Xia Xian, the main target for today, and said, "Today I will let you try the power of my tiger claws! From now on, the first place will be mine!"

"Uh." Xia Xian looked at him speechlessly, not sure where his confidence came from.
