After the crown prince was killed, the rest of the sins were already frightened, and they were soon captured by the Apocalypse Guard, and the battle lasted less than half an hour.

After returning to the camp of the Apocalypse, Xu Rui immediately ordered his subordinates to separate a tent, carefully disinfect the interior with a special disinfectant, and then pulled the drill in.

In the makeshift sterile room, there are three tables side by side, each containing a corpse, or a part of the body.

On the first table is a living human head, which is the first martial saint Zhuo Li who was killed by Xu Rui on the grassland.

On the second table is a complete corpse, which is the body of Hong Guangli, who has just died and was about to be taken away.

On the third table is the prince who was cut in two by Xu Rui's hand-held ion cannon.

Xu Rui walked to the first table with a solemn face and carefully looked at Zhuo Ligetu's head.

The strange thing is that Zhuoligetu has been dead for more than a year, but his head is still lifelike, not to mention that there is no sign of decay, and even the skin is still full of elasticity.

Originally, Xu Rui collected this human head, just to commemorate the first martial saint he killed, at that time, there was a shortage of soldiers on the battlefield, and after he collected the human head, he sprinkled it with slaked lime and stuffed it into the box, and didn't care much about it.

Unexpectedly, when the war ended, Xu Rui returned to Changxing City to find that the human head buried in the hydrated lime for several months was still intact.

Xu Rui had also examined this human head before, and found that the nerve reflex had stopped, and the brain had lost its response, which was a standard dead person.

However, his cells remained alive under the microscope, similar to the state of an animal hibernating, like a vegetative person.

The same situation also appeared with Hong Guangli and the crown prince.

One of them has been dead for more than ten days, and the other has just died for three hours, and under normal circumstances, there will be different degrees of changes, but at this time, it is like a living person asleep, and even the muscles are not stiff.

Especially the prince's corpse, the wound cut by the hand-held ion cannon actually grew flesh buds like blisters, as if he wanted to reconnect the body that had been cut in half.

This unbelievable phenomenon immediately aroused Xu Rui's curiosity, and this is the simple sterile laboratory in front of him.

After holding Zhuo Ligetu's head and studying it for a long time, Xu Rui still found nothing, so he simply put the head back on the table, and hurriedly pulled out the broken blade with a "cang".

The invisible sword qi was suddenly released from the broken edge, and only to hear a "click", the head of Zhuo Li Getu placed on the table suddenly split in half, and kept swaying on the table like a watermelon.

"Huh?"

Just as Xu Rui was putting away his sword, he was about to get closer to the severed head and take a look, and he immediately frowned.

"What did you find?"

Xu Rui asked suspiciously.

He pointed to his brain and said, "What is this?" ”

Xu Rui took a closer look, and his pupils shrank suddenly.

I saw that there was an extra golden organ next to the pituitary gland, this organ was not flesh and blood, but had crystallized, like a golden jade.

Miraculously, countless visible blood vessels protrude from the crystal, like spider webs connected to the brain, and it seems that the energy that keeps the corpse dead and immortal is continuously transported from these blood vessels to the corpse.

In order to confirm this guess, Xu Rui groaned slightly, and suddenly stretched out a finger and flicked it the crystal.

At this time, Xu Rui was already a first-class master, and the power of one finger was like a hammer.

Hearing only a "bang", the crystal shattered, and a terrifying qi suddenly gushed out like a storm.

However, due to the lack of conscious control, the qi machine was not in the slightest danger, but was fleeting, dissipating between heaven and earth in an instant, and the remaining crystals melted and evaporated in an instant like ice cubes, and disappeared in just a moment.

At the same time, the skull, which had lost its crystal feeding, withered and decayed rapidly at a speed visible to the naked eye, and after half a pillar of incense, it became a mass of foul-smelling carrion.

"This ......"

The scene in front of him was beyond ordinary cognition, and he was dumbfounded, his eyes kept wandering back and forth on his head and Xu Rui's face, and his eyes were full of shock.

Xu Rui's face sank like water, without saying a word, and came to Hong Guangli's corpse again.

The same hand rose and fell, and the invisible sword qi smoothly split Hong Guangli's head in half, and like Zhuo Ligetu, there was also a thumb-sized crystal next to his pituitary gland, the only difference was that the crystal was red all over, not golden.

"He also has ......"

To sink away from his eyes, he subconsciously touched the back of his head.

Xu Rui carefully examined the crystal and confirmed that it was no different from Zhuo Ligetu's golden crystal except for its color, and then walked towards the prince's corpse again.

The third time he took out the sword, this time he split the prince's body in half from the middle, and also found crystals in his skull, the only difference was that the color changed to light green, and the size was also two circles larger than Hong Guangli and Zhuo Ligetu.

"Could this be the legendary relic?"

Looking at these two crystals, he thought about it and suddenly asked.

Xu Rui smiled: "For those who practice martial arts, it can also be understood in this way. ”

"What do you mean by that?"

I want to leave and ask.

Xu Rui said in a deep voice: "If you guess correctly, these crystals should be formed by qi machinery, because the qi in the body of the martial saint is too large, so crystals will be produced in the body.

Or conversely, only those who can produce crystals in their bodies are likely to become martial saints, and among the three, the crown prince's qi is the strongest, so his crystals are the largest.

After the death of the Martial Saint, the crystals will not immediately disperse, and will continue to support the body that has died, so it will cause such magical phenomena as death and immortality.

But ......"

As he spoke, Xu Rui picked up the prince's corpse, pointed to the internal organs inside, and said: "Have you noticed that Tai's internal organs are very different from ordinary people, the heart has shrunk to the size of a fist, and it has basically lost its pumping function, while the lungs have become very hypertrophied and can absorb more nourishing qi."

The surface of his liver is bright red and looks very healthy, but the surface has hardened, and if it were an ordinary person, I am afraid that he would have died long ago.

There are also kidneys that are not normal two, but four that are only half the size of an ordinary person.

In this way, all the organs in his body are different from ordinary people, and they are a new life system built around crystals. ”

To leave: "I didn't expect you to have research on these, but you said so much, what can you prove?" ”

Xu Rui sighed and said, "It can prove an astonishing conclusion, the Martial Saint no longer belongs to human beings, but another kind of creature. ”

"What?!"

You have to leave the words and exclaim.

Xu Rui smiled bitterly and said, "Think about it, is there any martial saint who can still have children after becoming a martial saint?" ”

After thinking about it, his face suddenly became very ugly.

Xu Rui shook his head and said: "That's it, the fundamental reason why the bottleneck of the Martial Saint is so difficult to cross is that it is a completely different creature, and when you become a Martial Saint, you can no longer be regarded as a human being, and of course there will be reproductive isolation, and you will no longer be able to give birth to offspring with humans." ”

Saying that, Xu Rui patted the shoulder of the person who wanted to leave sympathetically and said: "Actually, it's not that there is no chance at all, you can try to find a female martial saint, maybe you can directly give birth to a martial saint?" ”

"Get out!"

wanted to leave Xu Rui's palm and glared at him hatefully.

Xu Rui shrugged his shoulders and didn't care, but he remembered another thing in his heart.

The universe is so big that there are no surprises, and it is not for nothing that living beings evolve from one creature to another, but they will never appear in nature, what is the reason for the appearance of a creature like Martial Saint?

Thinking about it, Xu Rui was suddenly stunned and asked: "Martial Saint's exercises, have all the Martial Saints in the world cultivated the Martial Saint's inheritance techniques?!" ”

Yao Li nodded: "I haven't paid attention to it before, when you say this, it seems that all the martial saints in the world have cultivated one of the thirty-six martial saint exercises, and there seems to be no exception." ”

"That's right!"

Xu Rui nodded and asked, "What exactly are the thirty-six martial saint exercises?" ”
