The value of demon crystal is very high. It is mainly used to arrange array. In addition, some special demon crystals can be used as medicine!

Compared with the Spirit Crystal in the spirit beast, the demon crystal is a lower level, but the value of the demon crystal from the rare bloodthirsty bat king in the hands of Chen Yu is not necessarily lower than that of the Spirit Crystal.

In particular, the violent energy inside this bloodthirsty demon crystal comes from the blood that the bloodthirsty demon bat sucks In this point, it has a natural similarity with the blood flame refining formula practiced by Chen Yu!

must know that this powerful and vicious method is also through the phagocytosis and integration of powerful animals, even powerful warriors, which contain the blood essence of great energy.

There is not much difference between the two in essence.

It was based on this consideration that Chen Yu thought of using this demon crystal of the bloodthirsty demon bat king to break through the bottleneck of blood flame refining formula!

According to Chen Yu's knowledge, the energy in the demon crystal is still a kind of vitality of heaven and earth, which can be directly absorbed and refined. Of course, this requires high-level warriors to do, and those with strength below the spiritual realm are unlikely to directly absorb and refine the demon crystal energy.

Most of the energy in the demon crystal is harmful to the warrior. It contains a trace of soul power in the running of the demon beast. Even if the lower level warrior has the ability to absorb energy from the demon crystal with stable and hard structure, he will never dare to try it easily!

Compared with absorbing and refining a demon crystal, it's easier and more cost-effective for the warrior to sell the demon crystal in exchange for elixir, and there's no risk of being possessed!

If it wasn't for the strange feeling in his blood when he held the demon crystal, Chen Yu would not have thought of directly absorbing and refining the blood demon crystal.

Of course, the risk is not small, but considering that under the environment of the tower, the powerful invisible pressure suppresses the manic and tyrannical energy in the demon crystal, Chen Yu feels that he can reduce the risk to the minimum!

Worst of all, the breath of emperor's bone will certainly play a role.

"The blood flame PA Lian Jue is double!"

Chen Yu's eyes flashed, showing a look of expectation.

Since his adventure in the Shenying mountains, Chen Yu has been fighting all the way. He often fights with those who are stronger than himself. He has gone through dangerous situations. Many times, he is in a situation where there is no doubt that he will die. But every time, he miraculously escaped from death Here, the skill of blood flame PA Lian Jue and its derived magic powers such as burning blood play a vital role!

Therefore, this kind of opportunity that can advance the blood flame Ba Lian Jue to the second level can't be missed!

Even if he failed in the end, Chen Yu felt that he had to try his best!

"I have reached the first peak of the blood flame cultivation formula, and my physique is stronger than the six layers of ink armor in Tiangang realm. If I can make a breakthrough here, it's no longer hard to get to the top of the tower! "

Chen Yu took a deep breath and put the demon crystal of the bloodthirsty bat in front of him. Then he slowly took out a real short knife from the storage bag and put it beside him.

Sitting with his knees crossed, Chen Yu pinched the seal formula in his hand and began to urge the blood burning technique in the blood flame refining formula.

The blood in Chen Yu's body is burning, and it is still surging under the strong pressure here!

It's obvious that the pressure on this tower can't suppress the anti heaven skill like blood flame refining formula.

Feeling the rolling of his blood, Chen Yu put down his hands, grasped the knife and cut the blade toward his left wrist.

The movement is still slow, but the sharp blade still cuts the wrist.

The blood seeped out.

Chen Yu gathered the blood toward the wound, put down his knife, grabbed the blood demon crystal, and pressed it on the blood gushing from the wound.

Under the deliberate control of Chen Yu, the whole blood crystal was soon stained with blood.

Chen Yu obviously felt that the demon crystal in his hand had become fiery!

Blood flame refining formula is practiced to the extreme. A drop of fresh blood can burn the void and last forever. Any treasure can be refined and even the supreme imperial ware can be broken with a drop of blood. Therefore, this change of demon crystal was also expected by Chen Yu, and he didn't think it was so surprising.

Although Chen Yu is far from the original form of blood flame, some special effects of blood have been reflected!

Put down the demon crystal, Chen Yu's hand is holding the seal!

Under the pressure of omnipresence, the seal changed slowly and difficultly several times. Then Chen Yu put his index fingers together and touched the demon crystal in front of him.

A wisp of dark, weak and tenacious breath is rising on the demon crystal.

The blood poured through the blood color demon crystal began to emit a trace of blood light.

Blood refining magic power!

Chen Yu is quite proficient in this magic power. It is another blood flame magic power that Chen Yu can display besides blood burning skill!

The art of blood refining, as the name suggests, is to use the blood containing blood flame to refine the powerful supernatural power of all things. This kind of supernatural power can be refined to the extreme, and all things can be refined. Even a powerful imperial instrument can be possessed by this supernatural power!Of course, Chen Yu is far from being able to refine this kind of demon crystal.

When the blood refining skill is finished, both hands grasp the demon crystal which becomes hot and emits blood light, and start to use the Xuantian Jue to activate and absorb the energy in the demon crystal!

Boom With the operation of xuantianjue, Chen Yu began to absorb vitality, and his arms were shocked suddenly. The blood light of Chen Yu was carrying the huge pressure everywhere, which soared a little, drowning Chen Yu's hands.

Chen Yu only felt a strange and gloomy atmosphere, which contained the meaning of tyranny, followed his hands into his body.

This is due to the tyrannical energy generated by the bloodthirsty bat King absorbing the blood of many monsters. Most of it directly entered into Chen Yu's blood. Chen Yu's blood began to run spontaneously and rapidly. The blood surged like a tide, and the tide was like a fire.

The other part of Chen Yu's Qi was destroyed and destroyed, which suppressed the Qi in his body, making him unable to resist, and even unable to refine this energy!

Chen Yu felt that his meridians were so painful that he was about to be torn apart!

Chen Yu had psychological preparation for this. His meridians had been reshaped by the blood flame Nirvana technique at first. He was tough and broad enough. Although it was painful, Chen Yu had confidence to bear it.

At the same time, Chen Yu only felt his heart shaking, and a kind of cruel and cruel strange emotion suddenly appeared in his mind.

In his heart, Chen Yu had a strong desire for blood. He wanted to bite the throat of any living creature and drink a lot of blood.

"This negative emotion is really amazing!" Awe inspiring in his heart, Chen Yu began to recite in a low voice a scripture of "pure heart and clear chanting mantra.".

This Scripture is just the one that xuantianzong's core disciple Fang is qualified to learn. This Scripture is not good for breaking through the realm, but it can make the martial arts keep their original mind and avoid being possessed by the devil. It is good for breaking through the spiritual realm to the mysterious and secluded realm!

As soon as the Scripture was read, Chen Yu's thirst for blood was weakened.

Chen YuYan's heart and soul were united.

Chen Yu only felt that his blood was like a glutton, constantly engulfing and fusing the energy from the blood thirsty bat King demon crystal. At the same time, the energy entering the meridians was also attracted, and directly flowed towards the intersection of Qi and blood and meridians, which was engulfed and refined by Qi and blood!

"So it is Chen Yu raised his mouth and looked relaxed.

The blood flame refining formula is really powerful. Although the bloodthirsty bat king is a fierce beast of the seventh level, it only causes a limited trouble before this powerful skill against heaven!

With a long breath, Chen Yu began to concentrate on chanting the mantra of qingxinming, dispelling the negative emotions in his mind.

With the passage of time, Chen Yu felt that the violent energy entering his body began to weaken, and the negative emotions in his mind began to disappear.

Then, Chen Yu only felt that his Qi and blood were more and more vigorous, almost overflowing through his pores. However, because of the existence of invisible pressure, this kind of blood overflow did not really appear!

Therefore, under such extreme pressure, the benefits are not small.

Chen Yu Ning felt the flowing blood. After laughing, he began to feel and control his heart beat according to the second method of blood flame refining formula.

All of Chen Yu's mind was focused on his heart. By controlling the beating of his heart, he used his mind to make the blood flow through his heart in a strange way, and then There are some strange but wonderful changes in the flow of blood!

This process is not easy, but it is the key to break through the double training formula of blood flame!

The power of blood circulation comes from the beating of the heart. If a person's heart is smashed, he will die. The importance of the heart can be imagined.

Chen Yu constantly controlled the frequency of the heart beat by reciting the relevant methods and paying close attention to it, showing a certain regularity!

It wasn't long before Chen Yu saw a very tiny "black scale cunning" in his own blood. This black scale cunning went up and down with his blood, sometimes scattered, sometimes combined, and scattered.

Then, Chen Yu saw a "bloodthirsty demon bat king", just like Wu scale cunning, who was also drifting with the blood!

Chen Yu could not afford to feel the slightest waves. He knew by nature that the two were a blood mark, showing the source of those essences in his blood. At the later stage of the cultivation, this mark will become the corresponding mark of the origin of the supernatural power!

Chen Yu devoted himself to cultivation and controlled the beating of his heart. Through the penetration of his mind, all kinds of changes constantly appeared in the surging blood, sometimes like a galloping horse, sometimes like a drumbeat, sometimes like a billow of stagnant water

With the passage of time, Chen Yu completely forgot himself and didn't feel hungry. He was completely immersed in the cultivation of Xueyan Balian Jue.

Finally, at a certain moment, Chen Yu opened his eyes fiercely with a trace of joy in his eyes.

In his blood vessels, the blood runs like a spiral. In this flow, Chen Yu can clearly sense the subtle vortices hidden in the blood. Although the blood flows at a very fast speed, it gives people a relatively calm feeling.If we say that Chen Yu's blood was surging like the tide before, now his whole body of blood has become a calm lake, and under the lake, there is endless turbulent undercurrent!

Blood flame is the second key, blood coagulation is like the sea!
