Cao Yun got up and turned around, but saw a big bird rushing towards him.

"Chengming Bird"

Cao Yun exclaimed, then turned over and lay down, dodging the impact of the Chengming Bird, and hurriedly took out the Demon Sealing Tower. With a "duh", the Demon Sealing Tower flew out of Cao Yun's hand and spun above Cao Yun's head, revealing a red light.

Cheng Ming Bird turned around and rushed towards Cao Yun again, Cao Yun turned back a few times, dodging a distance, the Demon Sealing Tower was still spinning in place, and the red light became more and more abundant.

The Chengming Bird also knew how to avoid the Demon Tower, however, just when the Chengming Bird flew up to the Demon Tower and wanted to avoid the Demon Tower, a burst of red light from the Demon Tower shot towards the Chengming Bird.

"Woo..."

Chengming Bird screamed miserably, and was included in the tower by the Demon Tower. The red light dissipated, and the Demon Sealing Tower spun to answer Cao Yun's hand.

"Fortunately, this demon tower can really work. "Cao Yun is a little afraid, this Chengming Bird is a three-grade demon beast, Cao Yun can't deal with it, not to mention that this Chengming Bird is still a flying demon beast, Cao Yun If he doesn't have this demon tower, he will really be buried in this eternal mountain area.

Holding the Demon Sealing Tower in his hand, Cao Yun's divine sense entered the tower. This demon tower has a total of nine layers, and this first layer is the one that seals the demon beast.

As soon as the divine consciousness entered the tower, Cao Yun saw that the Chengming bird had been sealed to a wall, motionless. However, Cao Yun knew that the Chengming Bird was not dead, but was just sealed.

Since the realm of the Chengming Bird is much higher than Cao Yun, Cao Yun can't use the Demon Sealing Tower to ban the Chengming Bird, of course, if Cao Yun's divine sense is strong enough, he can still seal the demon beasts higher than his own realm.

It can't be banned with the help of the Demon Tower, but it can be forced out with the help of the Demon Tower. Cao Yun immediately controlled the formation in the Demon Sealing Tower to force out all the essence blood of Chengming Bird, and the essence blood came out of the tower, and Cao Yun immediately inhaled it into his body and sat cross-legged on the ground and began to refine it.

You have to first convert the essence blood of the Chengming Bird into your own essence blood, and then convert these essence blood into vitality. After the transformation was completed, Cao Yun found that the essence blood of this Chengming Bird actually increased the strength of his body's meridians during the refining process, and after the essence blood was transformed into vitality, this vitality was even purer than before, and at the same time, the strength of his body also increased a lot, and Cao Yun also felt that the amount of strength had increased.

Cao Yun thought to himself: "Maybe refining the essence blood of demon beasts will be a shortcut to speed up the realm of martial arts, but I don't know if there will be any bad consequences, will it affect the achievement of innateness?"

Cao Yun hesitated for a while, "Forget it, no matter how much, now I have to hurry up to the fifth level of martial arts and return to Qingqiu Town, my father is still there, I'm afraid that the reason why my father is sick in bed and delirious is because of Ma Yiyuan." ”

Cao Yun's face became more and more gloomy when he thought about it, and the hatred for Ma Yiyuan in his heart rose to an unprecedented height, "Hmph, then what Erniang must have colluded with Ma Yiyuan." Thinking of this, Cao Yun's heart was even more like a wall rising, extremely uncomfortable.

Cao Yun stood up with a "snort", looked around, and decided to hunt demon beasts and refine essence blood.

If you want to ask what is the most in this ancient mountain area, everyone will answer the demon beast, of course, it has to be said that people with many plants think very differently from ordinary people.

Cao Yun didn't take a few steps before he found a demon beast dementor monkey, this dementor monkey was eating fruit on a tree, he didn't swagger close, this dementor monkey can have the ability to dementor, if ordinary people encounter it, they will inevitably be dementored by it.

Cao Yun still recited the mantra to urge the Demon Sealing Tower, and then made a movement to attract the attention of the dementor monkey, and sure enough, he shook a tree beside him, and the dementor monkey looked at Cao Yun at a glance, grabbed a branch and jumped towards him.

As soon as the dementor monkey jumped in front of Cao Yun, he was collected into the tower by the red light emitted by the Demon Sealing Tower, and it was not neat. Seeing that the collection of dementor monkeys was so smooth, Cao Yun strengthened his determination to hunt demon beasts to refine essence blood.

After Cao Yun finished refining the essence blood of the dementor monkey, the strength of the meridians further increased. As soon as he opened his eyes, he saw a three-eyed demon bear rushing towards him.

"I'll go. Cao Yun's first reaction was to get up and climb up the big tree beside him, and he was shocked into a cold sweat, this three-eyed demon bear is extremely powerful, and its claws are even sharper. Cao Yun climbed a tree in one fell swoop, however, to his surprise, the Three-Eyed Demon Bear could actually climb the tree and climbed up with it.

In a panic, Cao Yun hurriedly sacrificed the Demon Tower, and a red light from the Demon Tower swept towards the Three-Eyed Demon Bear, and he also successfully collected the Three-Eyed Demon Bear into the tower, but he was not very happy in his heart, because the red light of the Demon Tower was obviously smaller than before. The Demon Sealing Tower needs its own Yuan Force to urge, if demon beasts appear so frequently, if you don't wait for yourself to refine the essence blood of the demon beast to replenish the Yuan Force, the Yuan Force will run out. Thinking of this, Cao Yun's heart sank.

What he is thinking about now is not hunting demon beasts, but whether he can safely get out of the Eternal Mountain Domain, the frequency of being attacked by demon beasts is too great, and they are not ordinary demon beasts, and now Cao Yun doesn't know where he is in the Ancient Mountain Domain, and he doesn't know how much time it will take for Lu Dao to get out of the Ancient Mountain Domain.

"I'll go, this ancient mountain region is really life-threatening!" Cao Yun had to sigh, but at this moment, he saw a black shadow rushing towards him. Cao Yun reacted quickly, and immediately fell into the air, but the black shadow claw grabbed his chest, and immediately showed four blood marks.

The black shadow didn't wait for Cao Yun to react, and pounced again, where did he dare to block, but when he jumped, he still saw clearly that it was a three-eyed demon bear that pounced, how could the claws be blocked by his own little hands, so he had to dodge all kinds of things, and he didn't have time to sacrifice the Demon Tower.

At this moment, another demon beast also rushed over, and the first thing this demon beast rushed towards was not Cao Yun but the three-eyed demon bear, which gave Cao Yun a buffer time. The monster beast that rushed was the famous long-eyebrow white lion.

Where is the three-eyed demon bear is the opponent of the long-eyebrow white lion, scratched by the white lion's claw, the three-eyed demon bear wanted to escape, and after a few rolls on the ground, he got up and shot into the distance, but a red light immediately shot towards the long-eyed white lion and the fleeing three-eyed demon bear.

Seeing that the two demon beasts were included in the tower by the Demon Tower, Cao Yun breathed a sigh of relief, looked at his injured chest, grabbed some dirt from the ground and wiped it to cover up the smell of blood, otherwise he might not be able to attract any demon beasts!

After enduring the pain and smearing the soil, Cao Yun immediately sat cross-legged on the ground, and hurriedly refined the essence blood of the long-eyed white lion and the three-eyed demon bear, so as to replenish the yuan power.

After refining it, Cao Yun also felt that he had reached the peak of the second level, and he was only one step away from breaking through to the third level. However, Cao Yun felt that the strength of his meridians was now completely comparable to that of a martial arts triple person, but his physical strength was lacking.

Cao Yun opened his eyes, but heard a howl in the distance, the voice was a little miserable, but also a little familiar. Suddenly, Cao Yun remembered that the voice seemed to be the voice of the three-eyed demon bear, and Cao Yun felt a little bad.

The ground shook, and the trees in the distance also fell one after another, and Cao Yun was sure that some demon beast was rushing in his direction.

Cao Yun stood up suddenly, and his mind was thinking about how to deal with it.

"Huhu" A black shadow appeared in front of him, Cao Yun didn't see the face of the demon beast clearly, only saw the huge body.

"I'll go, Innate Demon Beast. Cao Yun shouted and turned around and ran away, judging from his body shape alone, he knew that the demon beast rushing to him was already at the innate level.
