The Supreme One

However, the reason I can say such big words is that there are actually not many popular physical fitness techniques on the market today.

Apart from the training hall's own inherited physical fitness techniques and several similar books on physical fitness techniques as reference substitutes, there are many types of physical fitness techniques in the school dormitories.

Apart from this, ordinary people who failed to fuse their bloodlines might choose to find a few books on body-strengthening techniques to study out of unwillingness, but monks basically do not have any body-strengthening techniques.

After all, they have passed this stage, and the most they can do is leave behind the physical strengthening techniques they once practiced as a souvenir.

Therefore, apart from Xia Xian who read through all the body-building techniques collected in the library, even some seniors who had some research interest in body-building techniques would not read them all like Xia Xian did.

Naturally, Xia Xian also learned a lot of these physical fitness techniques that were passed down in gymnasiums or families.

It was not difficult for him to improve the results of his practice.

As for how to improve the adaptability of a certain bloodline, you need to first understand why practicing specific physical fitness techniques can improve the adaptability of this bloodline.

The earliest body-building techniques were acquired by the ancestors of the human race through observing the body-building methods of other races.

Before the advent of physical strengthening techniques, people often looked for various spiritual objects to increase their physical strength through external forces, like Sheng Wuya.

The physical strength obtained in this way is not only weak in foundation, but also has an extremely low success rate for blood fusion.

Therefore, the number of monks at that time was extremely small, and only the big families could barely and stably support a monk in every generation.

As for ordinary people, they have no way to practice cultivation and are extremely weak, so they cannot search for spiritual objects in the wild at all. Therefore, they can only rely on gambling their lives!

Even if it is just the bloodline of an alien race at the spiritual level, if you want to merge it successfully, you have to pay the price of a large number of lives to barely merge one person.

At that time, the number of human cultivators was too small, but the resources of this world were extremely abundant. Even in Xia Xian's era, there was still a long way to go for a major situation such as a war due to resources.

Therefore, when there was no need to restrict others from gaining power and when more help was urgently needed, some human ancestors began to observe the natural body-building methods of various races.

Then he would teach the body-building methods he had learned to ordinary people for them to try.

At that time, in order to obtain useful body-building methods, the number of deaths in the experiments was several orders of magnitude more than the number of holes Xia Xian had opened on his body!

These are all lives that need to be consumed in order to practice this physical strengthening technique. However, no one, either at that time or in later times, criticized these pioneers for such acts that disregarded human life.

For the human race, although a large number of people were sacrificed, the human race was already in a precarious environment at the time. A human gathering place might be destroyed by a snoring of a strong alien!

Humans at that time were nothing more than snacks for aliens!

They live without any guarantee of life and without any dignity at all.

In order to break this status quo, the ancestors of the human race had to pay any price!

Of course, some of them are influenced by their blood and are completely loyal to certain foreign monks. Their starting point is to increase some available labor or food for their masters.

No matter what their purpose was, they ultimately helped to make the human race stronger.

As the physical strengthening techniques were gradually perfected, human monks also began to appear in large numbers.

That era can be said to be a major turning point in the destiny of mankind.

Later on, the emergence of spiritual food that strengthens the body marked another turning point in the fate of the human race, which led to a surge in the number of cultivators.

At that time, the physical training techniques that were developed based on observing the body-building methods of other races were all very primitive, and almost imitated the body-building movements of those other races.

However, correspondingly, while the physical strength is not improved much, the success rate of blood fusion can be increased a lot, because these primitive body-building techniques have unknowingly improved the blood compatibility a lot.

All the ancestors at that time wanted was to enhance the physical strength of the human race, but they did not expect that there would be an additional benefit.

This effect of increasing bloodline compatibility was discovered later after studying the concept of bloodline compatibility.

As for what bloodline compatibility is and how to test bloodline compatibility.

In fact, in Xia Xian's opinion, it was similar to an allergic reaction.

Different blood will produce different abnormal reactions after being injected into the human body.

Based on the harmfulness and intensity of these abnormal reactions, the specific blood compatibility is tested.

In other words, the more compatible the blood is, the less harm it will cause to the human body.

Before the invention of blood refining, the fusion of blood was done by injecting the blood into the body, allowing it to rush around in the body and forcing the person to endure it.

When the spiritual power in the bloodline is almost consumed and no longer resists, the fusion is considered successful.

Then, the spiritual power absorbed by this blood through the human body also takes on some of the characteristics of the human body, which is naturally equivalent to slowly refining it.

Only after successfully overcoming the initial resistance of the blood can treatment be carried out. Otherwise, the abnormal spiritual power entering the body may even cause the blood in the human body to explode directly.

The consequence is that the whole person explodes in one day.

If such an injury affects the brain, even the strongest monk will not be able to heal it.

It is only through the accumulation of a long period of time, generation after generation continuously integrating a certain bloodline, that the compatibility of the bloodline continues to accumulate and improve.

Even later on, strange creatures like earth dragons appeared.

Not only is the adaptability to the Earth Dragon bloodline maximized, but the integration of the Earth Dragon bloodline is a natural process.

Xia Xian even read in some books that some unusual geniuses like the Earth Dragons would not only not experience rejection when fused with corresponding bloodlines, but these bloodlines would actively release their spiritual power to heal and strengthen them!

It only takes a little time to quickly increase the degree of blood fusion to the maximum.

Xia Xian didn’t know what this was all about. Did the human race completely refine the bloodlines of these alien races in disguise?

Regardless of the reason, the knowledge Xia Xian gained from these books also allowed him to fully understand the essence of blood compatibility.

In fact, it is just the reaction of foreign blood in the human body.

Even humans would feel a little uncomfortable when arriving in an unfamiliar environment, and the same is naturally true for blood that contains alien power.

Correspondingly, as long as the similarity between this human body and the alien body is increased, or the comfort level is improved, it will naturally not feel such a strong sense of acclimatization.

Those primitive physical strengthening techniques and the physical strengthening techniques inherited from the training hall are to increase similarities, and what is accumulated from the integration of the same bloodline from generation to generation is actually comfort.

Each generation is integrated with the same bloodline, which will naturally affect their genes little by little, and they will be alienated by the bloodline to a certain extent, becoming more suitable for their own survival.

Correspondingly, it means allowing the alien blood to live more comfortably in their bodies, or in other words, allowing them to adapt to each other.

You refined me, but I also refined your body into my shape.

As it accumulates from generation to generation, it naturally makes the family members of the same bloodline feel more and more comfortable living in the bodies, and gradually they become reluctant to leave.

To increase the similarity, the natural way is to simulate the state of the source of this bloodline.

The more similar it is to the source of the blood, the smaller the difference felt in the blood by the human body, the lower the degree of acclimatization, and the weaker the resistance.

Although this simulation certainly cannot completely change a person's genes, it can still change certain aspects.

For example, the primitive version of the body-building technique is very similar to the body-building method of the aliens. The physical strength and structure obtained in this way will naturally gradually approach the physical condition of the aliens.

It’s a pity that even if these alien races allow humans to observe them, most humans only look at the external form, but do not really understand the actual core of these alien races’ body-building methods.

Of course, Xia Xian has not yet fully understood the physical conditions of any alien race, but by analogy, he has a deeper understanding of the bodies of alien races.

Starting from this higher level, the bloodline compatibility can naturally be improved to a higher level.

It is almost impossible to achieve complete adaptation, but it is still possible to greatly reduce the rejection of blood.

At least after Xia Xian optimizes the Tengu body-building technique passed down in the Tengu Training Hall, these ordinary people with mediocre qualifications will probably not be inferior to the geniuses in the school in the future.

Moreover, as time goes by, he will become more proficient in one thing and have a deeper understanding of Xia Xian's optimized physical fitness technique. The effect will be better when he teaches it to ordinary people, and it may even surpass that of the school.

Why do all the top or middle and high-level figures in Heliu City now come from the academy?

The reason for this is that the school only recruits a small group of top geniuses.

Secondly, it’s not about physical fitness, but about better resources.

Of course, those who still have family resources will become senior and top figures in the future.

Xia Xian felt that giving such feedback to Tengu Xiuguan was enough.

And this is actually not a big deal. Compared with those ancestors who had to completely sever their emotions and take ruthless actions for the future of the human race and did not take human life seriously, Xia Xian's experiment can be said to be too gentle.

It doesn't even leave any permanent injuries, isn't that gentle?

It just means that it will be more painful when holes are pierced in the body.

Although in Xia Xian's opinion, such human experiments need to be treated with caution, but for other people in this world, it is not a problem at all.

It's just a small hole or a cut on the body. The healing magic can fix it in minutes.

Even if there is danger, with Xia Xian's research ability, it is completely acceptable to use a few human lives for experimental research, even if it is the brain-boosting food and liquid.

Xia Xian carefully told Mo Li what he needed her to bring.

But after saying that, I was still a little worried, so I simply picked up a pen and quickly wrote a letter that was not much different from what I had just said.

After handing the letter to Mo Li, Mo Li's usually dull eyes now showed a hint of resentment.

In his eyes, was she really that stupid? She couldn't even let him feel at ease with a word?

Mo Li didn't want to say anything more, so he turned around and went home without looking back.

When Xia Xian saw Mo Li's little expressions, he could only smile awkwardly.

After so many years, I still treat her as the silly little girl she was at the beginning.

Maybe I can treat her like a big pear in the future?

Xia Xian thought about this, shook his head and smiled, then continued to do his experiment.

The next day, before Mo Li arrived, Master Bai Mulin returned to the library first.

"Xiao Xian, this material should meet your needs, right?"

Xia Xian picked up a gray-brown stone that Bai Mulin had placed on the desk and could tell the type of the stone at a glance.

A mineral containing trace amounts of metals, which, after becoming a spiritual object, has some sharp properties.

If forged into a weapon, it will be sharper than ordinary weapons.

If an ordinary person picks up this kind of mineral spiritual object, his skin may be scratched even if the surface is very smooth.

As for specific names, objects are usually not worthy of having their own signatures, and are often given the names of their spiritual objects.

But the world is too big, there are too many people, and there is no unified culture at all.

So even in Heliu City, there are many different names for this kind of mineral.

Some are less widely known and are simply named after their discoverers, or simply have names like "gray-brown ore" that don't have much specificity.

Xia Xian used the name "Sharp Gray-brown Blue Iron Ore" from his uncle's elixir.

That is to say, the various characteristics of this mineral are combined into one name.

After the uncle melted the ore, removed impurities and re-solidified it, it formed a blue metal.

However, Xia Xian had no idea whether his uncle had actually purified the ore completely and separately, but he didn't care too much.

All he needs to know is that this thing is indeed neither repulsive nor friendly to spiritual power.

This point indeed met Xia Xian's standards, so Xia Xian then opened his spiritual power perspective and took a closer look at the needs on the other side.

At this moment, he immediately discovered that there was an extremely solid layer of spiritual power attached to the surface of the stone.

It was like a piece of grayish-white glass that sealed the stone tightly, preventing the spiritual power of heaven and earth in the outside air from entering its body.

This is exactly the color of Baimulin’s own spiritual power. Influenced by the blood of the Undead, his spiritual power is filled with the meaning of death and extinction.

"Master, could you please drain the spiritual energy from this room first, and then remove the blockade on the stone and see."

Bai Mulin nodded, and with a thought, the spiritual power in the room was quickly dispersed outside the house under his control. Then the giant tree in the library emitted a green spiritual power barrier, sealing off the entire room.

Then Bai Mulin took the grayish-white spiritual power back into his body.

This is an ability that is acquired after reaching the state of divine manifestation. As long as it is within the range covered by the soul power, even if the spiritual power is released from the body, it will not be purified by the power of heaven and earth.
