In the crypt cell, a scatter test is conducted every three months. In these three months, the scatter test will last for more than a month, and then the young Jiao will need to cultivate for more than a month.

The young Jiao who survived the initial trial no longer had much life-threatening in the follow-up trial. And with each experiment, their strength increases dramatically, and they become stronger and stronger. It's just that after more than a dozen experiments, they have surpassed the leaders of the Jiao clan peers in the outside world, and they have become the Jiao clan Tianjiao in the unknown world.

And in order to protect his bloodline, Ao Che exchanged blood by cultivating the "Blood Xuan Sutra" after each test, and minimized the impact of the test on his body as much as possible, although this protected his own Qinglong bloodline, resulting in each subsequent test starting from scratch like the first time, which was extremely dangerous, not as easy as other young Jiao.

In this way, year after year, after one experiment after another, a steady stream of new young Jiao Jiao was constantly replenished.

Finally, ten years have passed.

The last batch of young Jiao in the same batch as Ao Che has also been promoted to a prefecture-level test subject, and Ao Che knows that he can't rub around here anymore, which will seem unusual and attract attention.

In the past ten years, Ao Che has experienced more than forty scatter-level tests, and the Qinglong bloodline has also become stronger in the struggle with the power of the reagent again and again, from being at the bottom of the struggle with the reagent at the beginning, to being evenly divided later, and then completely suppressed. By now, the Qinglong bloodline occupied most of the space in the bloodline, and the reagent power was huddled in the corner but could not be completely removed, and the two formed a strange balance in his body.

Fortunately, the reagent power in Ao Che's body has been in a hidden dormant state, so Ao Che's dragon scales still remain dark blue. But he knew that once the power of these reagents burst out, it would make his dragon scales say goodbye to the dark cyan.

After the next few tests, Ao Che weakened the strength of the exchange transfusion and gradually relaxed the suppression of the power of the reagent. Soon his scales began to change color slightly.

Finally, after another test, the blood-clad warlock stood in front of Ao Che and commented, "C36, the forty-fourth scattered test, the blood vein concentration has reached thirteen, and it is evaluated as an excellent grade test subject. ”

After saying that, the blood-clad warlock looked at Ao Che and sighed in admiration. The young Jiao in front of him has undergone ten years of experiments, and the bloodline concentration has only climbed to three, he has already identified a young Jiao as a waste material in the test body, but he did not expect that the last few tests of this young Jiao began to advance by leaps and bounds, the bloodline concentration from five to seven, and then from seven to nine, this time it directly broke out to the concentration of thirteen, greatly exceeding the requirements of ten, it can be said that it is the best test subject for promotion this year, and it is expected to pass the follow-up prefecture-level test, and then become a more advanced god-level test subject. But that's not what he, a loose warlock, can care about.

At the end of the evaluation, Ao Che and another young Jiao who had been promoted at the same time were taken out of the crypt prison by the Blood-Cloaked Warlock.

......

Mayfly Cave, a prefecture-level cave.

Ao Che and the young Jiao were led into an unusually wide cave by the blood-clad warlock, and as soon as they entered through the entrance, they could see a wide square, and there were many small openings connected to the cave walls on the side of the square, and the young Jiao could occasionally be seen entering and exiting here. Inside these caves is where these prefecture-level test subjects live.

The Scattered Warlock took them to a huge cave, handed them over to another Warlock, and left. Unlike the two scattered warlocks in the crypt prison, this warlock had some silver patterns on his bloody clothes, and he obviously had a higher status.

The warlock looked at Ao Che and the two of them and said, "I am the ground-level warlock in charge of this place, and you two will live in the Cave Mansion in the future." Although you have entered here, you are not really a prefecture-level test subject, just an alternative, a quasi-ground test subject. You are not yet eligible for an identity number for a prefecture-level test subject. Only after you have experienced the first prefecture-level test can you be called a real prefecture-level test subject, and you are eligible to obtain a prefecture-level identity number. ”

Youjiao, who came with Ao Che, said confidently: "I will definitely get the prefecture-level number and become a real prefecture-level test subject." ”

In his opinion, he is already among the Jiao Clan's Tianjiao, and it is not a problem for him to pass the prefecture-level test. Moreover, this prefecture-level test will definitely bring him more powerful power, and it will be an invitation for him to become a strong man.

However, Ao Che smelled a hint of dangerous qi and asked aloud: "May I ask my lord, is it very dangerous to go through the ground-level test for the first time? Will we face a terrifying screening again like the first time we go through the scatter-level test?"

Ao Che still remembers the horror after the first scatter test, the explosion and death of a large number of young Jiao test subjects in the entire prison, and only a dozen of them survived in the end, and he didn't want to experience such a cruel scene again.

Hearing this, the ground-level warlock glanced at Ao Che and nodded, "You are very smart. As you said, a quasi-prefecture-level test subject must go through the screening of the first prefecture-level test and survive before it can become a real prefecture-level test subject. Not only that, but in fact, the four tests of heaven-level, god-level, earth-level, and scatter-level will have a screening of test subjects. If you survive it, you will live, and if you can't survive, you will die on the spot. ”

"And the higher the test grade, the more stringent the selection of test subjects becomes. When the test subjects go through the scatter level test, 30% of them can survive, and when they go through the ground level test, only 10% of the original surviving test subjects can continue to survive, and when it comes to the god level test, this time only less than half of the previous number will be lucky to survive. ”

"Every year, thousands of young Jiao are captured in the mayfly cave, but only one or two can become god-level test subjects in the end. As for the higher heaven-level test subjects, no test subjects have reached it until now. Originally, the Six Kings Sun of the East China Sea caught in the Mayfly Cave could become a heaven-level test subject, but the Six Kings Sun had been missing for ten years and still had no trace. And the Dragon Palace has stopped searching, and it is likely that the Six Kings and Suns have been found. Now, the hope of the Heaven-level test subjects is only in you test subjects. ”

After the ground-level warlock finished speaking, he couldn't help but sigh.

After hearing this, Ao Che's heart couldn't help but ripple. This was the first time he had heard from outside since he entered the mayfly cave. It turned out that Ryugu had stopped searching for him. Ao Che sighed in his heart, knowing that things should be like this, but he was still a little sentimental.

At this time, the earth-level warlock took out two pills and said, "Here are two great tonic pills, you can take them after you go back, they can help you regulate your body and prepare for the future earth-level trials." The next trial is at the end of next month. It is hoped that you will be one of the 10% survivors of this approved prefecture-level test subject. ”

Ao Che nodded in silence, while the young Jiao who was traveling with him was angry with fighting spirit in his eyes. The Ground-level Warlock nodded and sent them away.

In the Cave Mansion, Ao Che and his companion Youjiao moved in.

There are already a dozen or so new quasi-prefecture-level test subjects living here, and they are the quasi-earth-level test subjects sent from other crypt prisons. Because I knew that the end of next month would be the first prefecture-level test that would decide life and death. So they didn't waste too much time greeting each other, and they were all going all out to cultivate to deal with the upcoming terrifying screening.

Finally, the time for the prefecture-level trial has arrived.

Two earth-level warlocks came to the cave, and they still had blood balls in their hands. The blood cells containing the ground-level reagent were more refined and deep than the color Ao Che had seen before, and they could see that there were wisps of gold inside.

The two warlocks in this ground-level test were not as rough as the scatter-level warlocks, but let the young Jiao turn into prototypes, and after they were in a good posture, they picked up the blood balls and put them close to the neck of the young Jiao one by one.

When it was Ao Che's turn, Ao Che felt that this time the roots of the blood cells were implanted deeper under the skin, almost deep into the bone marrow. And his spine was as hot as red-hot iron, as if it was about to poke out of his body. Distorted blood erupted from the neck, as if it were about to burst the blood vessels around it.

Ao Che's will fell into a coma again. Before he fell unconscious, he saw a young Jiao burst on the spot because he couldn't bear it.

Ochher didn't know how long he had been in a daze, but when he regained his senses, he felt like he was in the dark.

"Where is this? Am I dead after a failed experiment?" Ao Che couldn't help but panic when he realized that he wasn't in the mayfly hole. He speculated as he searched for a way out in the dark.

Suddenly there was a sound of running water in front of him, Ao Che's eyes lit up, and he stepped forward quickly. A stream suddenly appeared in the darkness. The stream was red, like a jewel of blood, flowing towards the end of Ao Che's feet.

For some reason, Ao Che suddenly felt relieved and comfortable when he looked at the stream, as if he had a close connection with the stream.

At this moment, there was a sudden roaring sound from the other end of the dark space. Ao Che walked in that direction, and suddenly saw a river of blood rolling in him. Although the river is powerful, there is always a rotten and turbid atmosphere.

"What's going on?" Ao Che looked at the surging river of blood, and unconsciously worried about the stream before.

The raging river rushed into the creek and swept to the feet of Ao Che, and the original stream was squeezed aside. In the same waterway, the stream and the river are distinctly distinguished, one river is blood-colored and turbid, the other is blood-clean as a jewel, and the stream is squeezed only two or three steps wide, as if it is about to be swallowed up by the river and disappear.

Ao Che looked at the scene of the river taking over the road and the stream weakening, and his heart became irritable for no reason. He suddenly realized that this stream must be closely related to his Qinglong bloodline, and that river was the power of the ground-level reagent.

Ao Che felt that if he wanted to keep his green dragon bloodline pure, he had to stop the river from eroding the stream. It's just that at this moment, he doesn't know what kind of dream he is doing, and if he can't wake up, he can't cultivate the Blood Xuan Sutra to exchange blood. Moreover, such a terrifying ground-level reagent power cannot be eliminated by a simple exchange of blood.

In this situation, the only way he could think of was to explore the upper reaches of the creek and open up the width of the upper waterway of the stream, so as to alleviate the erosion of the creek by the river.

Ao Che made up his mind and walked along the direction of the stream. The higher the stream, the deeper the waterway became, and gradually, the stream overflowed Ao Che's knees, lower body, upper body, and top of his head. Ao Che also changed from going up at the beginning to going upstream.

And the further upstream, Ao Che felt that the wider the stream, the greater the resistance, and finally Ao Che saw a wide water surface appear in the upper reaches of the stream. It can no longer be called a stream, but a river.

The river entered the entrance of the stream, and the current suddenly became fierce, and the strong and pressure will try to cross the Aocher, repulsed several times. In the end, Ao Che gritted his teeth, swam under the huge water pressure, and finally entered the river.

The moment Ao Che broke through the water, he froze where he was, almost swept away by the river, and then came to his senses and swam forward frantically.

"Father!" cried Ochher.

Just now on that section of the river, Ao Che saw a figure, it was his father, Zhehai Longjun.

Seeing his father here! Ao Che seemed to see the dependence, and his whole body became excited, and he struggled to swim forward.

He lived cautiously in the Dragon Palace of the East China Sea for more than 200 years, without the protection and guidance of his elders, and then he fell into the mayfly cave and died nine times, and there were no elders to stand up for him and try their best to save him. The struggle to survive alone is too hard, and Ao Che can't wait to get back to his father.

Coming to the river again, Ao Che stared intently at the scene that had been hastily swept before: a slightly young father wearing a nine-chapter dragon robe and holding a long lance, fighting with a figure with golden wings on his back.

The Nine Chapters Dragon Robe is the costume of the Dragon Prince, which is when his father was still the fourth prince of the East China Sea Dragon when he was young. And the opposing side is obviously also extraordinary, a dazzling royal robe is not far behind, embroidered with the sun, moon, stars, clouds, birds, fire, thunder and other lines, this is the style of the royal robe in the heavenly palace.

The moves made by the two sides are full of power, the father blows with a long lance, divides the mountains and the sea, the enemy's golden wings flutter, swaying thousands of miles, and the two are inseparable.

Ao Che was disappointed to find that this scene of the battle took place in the past. All that was in front of me was a silent picture, floating quietly over the river.

Ao Che observed his father's battle up close, if it was a normal day, he would not be able to get close to this level of battle at all, but at this time, he was able to observe it carefully and gained some very valuable insights.

After watching the whole battle, after his father severed the enemy's spine with one blow and won the victory, the picture started again, Ao Che waved goodbye to his father and continued to move towards the upper reaches of the river.

And at this moment, suddenly the river chirped. Ochher noticed that the entrance of the river into the stream seemed to be much wider. The flow of water injected downstream has become a little thicker. Ao Che suddenly realized that it had something to do with the footage of his father's battle after he watched it.

Because of this change, Ao Che rewatched the battle screen several times. After researching, he finally realized that the more he comprehended from this picture, the more open the entrance to the downstream became. And when he wrote down the dance lance technique used by his father, the entire downstream was three points thicker.

Ao Che was inspired by this, but he was already unable to gain new insights from this image, and it was time to move on, perhaps with such a picture ahead.

Leaving this section of the river, the resistance of the upper reaches of the river increased again. It became more and more difficult for Ao Che to move forward, and it took a long time to advance a little, and if he slackened at all, he would immediately be swept away by the river for a long time.

Ao Che could only muster up his strength, and swam until he was exhausted, and when it was difficult to advance any more, a dragon groan sounded, and Ao Che turned into a green dragon, and then swam upstream.

The green dragon is always good at water, and Ao Che swam forward again for a long time with the body of the green dragon, and finally came to a new river basin, where the water is wide and has formed a huge lake.

Ao Che swims through the lake, triggering a scene again.

It was a picture of his grandfather, the Dragon King of the East China Sea.

The Dragon King of the East China Sea sat in the void, and behind him was a deep sea eye, from which endless sea water gushed out, filling the entire space. In front of him, a golden Buddha sits on a golden lotus, and his whole body blooms with golden light.

The Dragon King and the Golden Buddha did not move for a long time, but the golden light and the sea water in the space were fiercely contending, exuding a powerful destructive power.

Ao Che watched this scene for a long time, and he remembered that there was a volume of "The Dragon King of the East China Sea Zhenhai Jing" hidden in the school palace, which depicts the scene of the Dragon King of the East China Sea suppressing the tsunami, which explains the many water spells cast by the Dragon King of the East China Sea, which is a compulsory course in the school palace.

At this moment, Ao Che observed the battle scene between the Dragon King and the Golden Buddha with his own eyes, and one after another water spells were cast, which gave Ao Che a new understanding of the "East China Sea Dragon King Zhenhai Classic", and the water spells also went to a higher level.

When Ao Che finished watching the picture, the feeling ended. The inlet of the lake into the downstream river also becomes larger. Ao Che was overjoyed, his conjecture was correct.

After lying in the lake for a long time, Ao Che finally left the lake and headed upstream again. As soon as he swam out of the lake, Ao Che felt a strong resistance in the river, which instantly swept him back. Several attempts were made back to the lake. Ao Che quickly understood that he was not yet capable of going upstream.

Ochher turned and swam towards the end of the stream he had set out from. Back at the starting point, Ao Che was surprised to find that the stream, which was originally only a puddle of water at the end, had doubled in size. Although it is still small, there is no danger of being swallowed up by the river for a short time.

Ao Che was relieved, and then set his eyes on another river, what does this foreign river look like?
