The members of the mayfly cave are divided into two types: mayfly guards and warlocks.

The mayfly guards are the guard force of the mayfly caves, responsible for capturing test subjects, defending battles, etc., and are generally dressed in black. Warlocks are the technical members in charge of experiments, responsible for various experiments and research, and generally wear bloody clothing.

And the Mayfly Cave Lord is the ruler of the entire Mayfly Cave, controlling the life and death of all members, and his clothes are special cyan.

In the crypt prison, Ao Che has been locked up for more than a month, and every day two warlocks in charge of the scatter level test will enter the prison to feed each young Jiao a pill. Obviously, these pills are regulating the blood qi of the young Jiao's body, in preparation for the subsequent experiment.

Finally, one day, two Scatter-level Warlocks reappeared, only this time they were no longer holding the elixir, but each holding a blood-red bead in their hands.

However, seeing a completely different scene from the past, the young Jiao in the crypt nervously avoided and secretly observed.

One of the warlocks reassured: "Don't be afraid, this is just a rudimentary experiment, you only need to plant the test potion in this blood bead, and it will be over very simply." ”

However, when they heard that they were going to be inoculated with reagents, the young Jiao was even more panicked and dodged into the depths of the cave.

Seeing this, the other warlock frowned, and said impatiently: "Why are you talking to them so much, just catch them and test them directly." ”

As soon as the words fell, a blood-red rope flew out of his sleeve, tied up and dragged out dozens of young Jiao in the corner, and hung in front of him, and then the blood-clothed warlock urged the beads in his hand, and several blood-colored beard buds came out of the blood beads, turned around in the air, and then stretched out to them in the screams of the young Jiao.

Soon I heard a "pop", these whisker buds stuck to the necks of those young Jiao, and then continued to drill under the skin of the young Jiao, and suddenly the young Jiao screamed in pain, and finally fainted in less than a moment, completely silent.

Seeing that his kindness was not understood, the other warlock sighed, and also took out a rope to tie up a dozen shivering young Jiaojiao and inoculate them with reagents.

Wave after wave of young Jiao fell into a coma after being inoculated with the experimental potion, and finally a warlock came to Ao Che and pulled him in front of him along with several other young Jiao, and then the blood beads in his hands stretched out their beard buds and stabbed them.

Ao Che felt a slimy beard bud stick to the dragon's neck, then pierced the skin, deep into the flesh, and finally into the dragon's back, and the process became more and more painful, until in the end Ao Che felt as if he had been decapitated.

Then Ao Che could feel a fiery trickle pouring from the bearded buds into the dragon's back, which was supposed to be the test potion that the white-clad warlock was talking about. And the injection of this reagent also brought Ao Che a tearing body-like pain, as if a blazing current was expanding wildly along the blood, and there was a fierce rejection reaction all over the body, and the body began to heat up, and his consciousness gradually blurred. In the end, he unconsciously coiled his body and fell into a coma.

In reality, Ao Che's body had begun to heat and red, and under the dragon scales on his neck, red blood vessels bulged out, expanding in all directions towards his body, accompanied by the violent trembling of the dragon's body due to pain.

In the crypt prison, all the young Jiao were finally inoculated with reagents and lay down on the ground, leaving only two warlocks standing in the cave.

"You say, these young Jiao have been inoculated with reagents, and how many of them will survive in the end?"

"Although the inoculation is only a bulk reagent, but the amount of reagent is far more than in the past, the rejection reaction will be much more intense, in the past, forty percent of the young Jiao can survive, this time there are probably two achievements are good. ”

"Eh! the Heaven-level test subject has been lost, and in order to produce as much as possible a spare Heaven-level test subject, all the tests have been increased in strength. This year's batch of test subjects may be the fastest to die. ”

"That's just their bad luck! Anyway, we just need to record the results, regardless of the survival rate. In a month's time, you and I will check the results. ”

The two warlocks walked out of the cave as they talked, leaving the unconscious young Jiao behind.

......

In his slumber, Ao Che felt as if his body had become a huge battlefield, in which a powerful force was rampaging and wantonly eroding, and then met fierce resistance from the whole body. The two forces broke out one battle after another in various parts of the body, causing the body to collapse several times.

The fatigue of the body weakness made Ao Che just want to sleep for a long time, but Ao Che always gritted his teeth and insisted on not slipping into the abyss of consciousness, and slowly he survived the most difficult period, the rejection reaction in his body had weakened, and his energy began to repair.

Eventually, Ao Che woke up from his slumber.

When he opened his eyes, Ao Che felt that he was about to be burned dry, with many cracks in his body, and dried blood everywhere on the dragon scales, which looked miserable.

And the whole cave is still silent at this moment, one by one the young Jiao have turned into the original form and lie in the cave, most of them have been dead for a long time, the body has collapsed, and the blood under the body flows to the ground, dyeing the ground of the cave red.

Only a few young Jiaojiao are still holding on, they coil up their long Jiao bodies, guarding themselves, and the qi is still hovering between light and extinction.

Ao Che was the first test subject to wake up, but this was normal. After all, as a dragon, his qualifications are much better than these young Jiao, and he is also a heaven-level test subject carefully selected by the Mayfly Cave, with pure green dragon blood on his body, which is enough to resist the impact of this experiment.

Ao Che moved his muscles and bones, gradually letting go of his coiled body, and peeling off the coagulated blood clots on the dragon scales little by little.

Suddenly, Ao Che noticed that after the blood clot fell off, the color of the dragon scales revealed was a little lighter than before. Suddenly, his face turned ugly.

Ao Che's dragon scales are a very special dark cyan color, which is the unique color of the green dragon, and is related to the ancestor of the ancient period, the Qingdi.

According to the history books of the dragon clan, the dragon scales of the Qing Emperor were originally pale blue, but after he created the Great Dao, his body underwent a transformation, and the dragon scales also became cyan. This color is unique in heaven and earth, marked by the Great Dao, and there will be no second cyan dragon in the world, only the descendants of the Blue Emperor can inherit this color.

Therefore, the dark blue dragon scales are the symbol of the orthodox green dragon. And the change in color of the dragon scales means that Ao Che's green dragon bloodline is quietly changing.

"This reagent actually has the power to tamper with the blood of the green dragon. Ao Che was shocked.

Ao Che didn't expect that the experimental potion in the mayfly cave contained such a powerful power, and it could actually compete with his green dragon bloodline, and tenaciously stayed in his bloodline, which affected him.

He vaguely foresaw that with the increase of future experiments, the green dragon bloodline in his body would be eroded little by little, and finally tampered with into a new bloodline, which Ao Che could not tolerate no matter what.

Ao Che has always been extremely proud of being a green dragon bloodline. The ancestors of the family came from the blue wisps of the road, overcame thorns and thorns, and established immortal achievements, which created the reputation of today's Qinglong Ao clan. These glories and the legacies of these ancestors still shadow the descendants of their families, making Ao Che infinitely reminisce. Ao Che is proud to have the blood of the Green Dragon flowing and to be a member of the Green Dragon Ao Clan.

But if his bloodline has changed, will he still be the original him? Is he still his father's son? and is he still eligible to be counted as a member of the Qinglong Ao clan?

Although he can feel new power now, if he chooses to change his bloodline in pursuit of power, this kind of behavior is like betraying his ancestors for the sake of power, it is a kind of dirt on the bloodline, a betrayal of the family.

What's more, the Qinglong bloodline is the top bloodline of the Three Realms, with the most top-level potential, and the ancestors of the past generations have already buried the richest treasures in it, so why should Ao Che go to the near and far to pursue other powers?

Ao Che firmly defends his bloodline in his heart, he will never accept tampering with the bloodline, but how can he restore the tampering of the bloodline by this reagent?

Ao Che suddenly thought of a "Blood Xuan Sutra", which was a collection of evil secret techniques in the school palace. It is about a shortcut to purify the bloodline - blood exchange. The content is divided into two parts, the first part talks about the method of transporting blood qi, which can quickly and prevent bloodletting, and the second part talks about the method of hematopoiesis, which can quickly make the body make new blood and restore blood supply.

At present, blood exchange is the only way to expel the reagent and affect the restoration of the Qinglong bloodline. Through bloodletting, the already dirty green dragon blood is excreted from the body, and through hematopoiesis, the body is regenerated into pure green dragon blood. As long as he controls the speed of bloodletting, he can change the blood all over his body and restore the blood.

Ao Che tried to recall the specific content of the "Blood Xuan Sutra", and then gritted his teeth and cut a part under the dragon's neck, and the dragon's blood flowed out. Ao Che closed the dragon's eyes, his mind was tightly closed, first turning to the method of transporting blood qi, and then running the method of hematopoiesis, these two methods were constantly performed at intervals, carefully controlling the speed of the body's blood exchange.

And when Ao Che was cultivating the "Blood Xuan Sutra" to exchange blood, as time slowly passed, the outside world began to change.

First of all, there was an occasional explosion of "bang!" in the quiet cave, which was another young Jiao who insisted on failure, his body burst open and shed blood, and the coiled Jiao body also loosened, and finally turned into a corpse and fell to the ground.

Later, some of the surviving young Jiao began to wake up. Gradually, more and more young Jiao began to wake up. Even the Scatter-level Warlocks reappeared, and they recorded the results of the examination of each awakened young Jiao.

And Ao Che is still cultivating the Blood Xuan Sutra.

Finally, when he changed the blood veins all over his body, the dragon scales also quietly turned back to dark blue. Ao Che woke up again.

A warlock stood in front of Ao Che and said, "Bingsanliu, I only woke up after a month and a half of being inoculated with a powder-grade potion, and my qualifications are average. ”

After speaking, the blood-clothed warlock took out another blood needle, pierced it into Ao Che's body, pulled it out after a while, looked at the scale on the needle and said: "The blood vein concentration is one, the degree of transformation is extremely low, and it is evaluated as a scatter-level test subject." ”

The warlock recorded the information, and then said to Ao Che: "Bingsanliu, the degree of blood vein transformation after you are inoculated with the powder level potion is too low, you have to carry out the powder level test in this crypt prison until the blood blood concentration reaches ten, and then you will be rated as a prefecture-level test subject, go to the prefecture-level living quarters, and conduct the next level of test." Do you understand?"

Ao Che nodded and did not speak.

After the warlock had finished saying these words, he left with the two young Jiao.

Those two young Jiaojiao were obviously different from other young Jiao, their cyan scales were pale blue, and their bodies had grown a lot. Obviously, these two young Jiao have good qualifications, and they were successfully promoted to prefecture-level test subjects in the first experiment, and went to that prefecture-level living area.

There are still a dozen or so young Jiao and Ao Che as companions in the crypt prison, and they are all surviving loose test subjects. There were also more than a hundred corpses of failed young Jiao lying on the ground, and they were quickly pocketed and cleaned out by another warlock.

In the end, in this crypt that originally had hundreds of young Jiao, only a dozen of them remained. It's a place where life really fades away so easily.
