After returning to the Thunder Fist Sect, Chen Zheng and the others rested in the Thunder Fist Sect for a while, then boarded the flying boat again and flew towards the black plain where the Demon Prison was located.

Chen Zheng had already discussed with the people of the ancient mermaid clan to go to the Demon Prison to have a look, and the mermaid princess, Yu Zuo and Yu Right and others all agreed.

The Demon Hell would open in eight days, and there were still four days left from the Thunder Fist Sect to the Black Plains, so there was not much time to rest, so they decided to go to the Black Plains to rest.

Lei Yu took all the elite disciples of the Thunder Fist Sect with him, and did not leave the masters in charge. At the beginning of the Demon Prison, the first thing for the major forces is to go to the Demon Prison, and the Qingyang Sect is no exception, and they will definitely not send people to attack the Thunder Fist Sect at this time.

The flying boat black dragon was speeding in the sky, driven by several disciples of the Thunder Fist Sect arranged by Lei Yu.

The rest of the people were all cultivating in the flying boat, and Chen Zheng was also liberated, and he sat in the burning chamber with Luo Fei, Dong Qianhan, Guihai Yijian, Guihai Yuting and others, and cultivated separately.

Chen Zheng summed up his cultivation and combat experience in recent times.

The combination of the original qi wings, the dragon emperor combat boots, and the fish and dragon variety can make his speed faster, and even the martial artists of the eight stars of the Spirit Martial Realm can catch up with him. However, he felt that the cooperation of the original qi wings, dragon emperor combat boots, and fish and dragon variety was not perfect enough, and there was still a lot of room for improvement.

With his original qi cultivation and proficiency in the variety of fish and dragons, it was not enough to bring out the true power of the Dragon Emperor's combat boots. However, he understands that this is not in a hurry, and his cultivation strength still needs to be improved step by step, and his proficiency in the ever-changing needs to be constantly honed in actual combat.

His cultivation realm is stable at the five-star Lingwu Realm, and if he wants to improve in a short period of time, it is not a big problem, but Chen Zheng doesn't want to improve in such a hurry, he wants to suppress it, and strive to be steady and steady, and take every step well.

Although the soul power is improved every day, the cultivation realm has not improved, and it is thought that after the soul power enters the sixth grade, it is very difficult to improve. However, Chen Zheng had already prepared for it, so he did not show any signs of frustration.

The soul power is mysterious and powerful, although he is already a sixth-grade soul master, but his grasp of the use of soul power is still relatively superficial.

After summing up the experience, he decided to study the soul power well, and strive to make the soul power exert a stronger combat power.

His soul body has cultivated the "Great Sun Thunder Body" to the fullest, and after the baptism of the Thunder Tribulation, his soul body has become very powerful, and the soul out of the body in broad daylight is like a wild street.

Moreover, his soul can be divided into two, one part out of the body and one part in the body, so that after the soul is out of the body, the thinking and activities of the body have a lot of influence.

So, he began to study the division of the soul into three parts, one part of which remained in the body and the other part of the body at the same time, doing different things.

With the experience of one soul for two, it was not difficult for him to divide the soul into three, and it only took one day for Chen Zheng to do it.

He tried to divide his soul into four, but found that with his current soul power cultivation, after dividing his soul into four parts, each part was very fragile and could not play a role, so he ended his plan to divide his soul into more parts.

After finishing the study of the soul clone, he began to study another powerful secret art, the "Beast Control Technique" passed on to him by Zhi Lao.

At that time, to deal with the encirclement and suppression of the three major forces of the Ji family's ancient clan, Wanjianmen and Poison Valley, Zhi Lao hastily passed on this strange martial art to him.

Although this martial art can't improve one's own cultivation realm, it can definitely improve one's own combat effectiveness, and the opportunity is to cheat.

In a sense, it is a very powerful martial arts.

Chen Zheng imagined that if he could control the eighth, ninth, or legendary divine beasts with the help of the "Beast Control Technique", then he would be able to sweep across the Wild Martial Continent.

"I just don't know, can this martial art control those powerful demon beasts?"

Chen Zheng immediately carefully studied the "Beast Control Technique" passed on to him by Zhi Lao, but unfortunately there were only a few words on it to control the eight-rank soul beast, and there was no method to control the nine-rank and divine beasts.

With a wry smile, Chen Zheng felt that he was thinking too much, the Nine Rank Demon Beasts and Divine Beasts were all legendary existences, and their cultivation strength was comparable to that of the legendary Emperor, how could they be controlled by others casually.

Familiar with the method of "Beast Control", Chen Zheng studied the runes on the ancient monument of the Great Wilderness.

The runes on the ancient monument of the Great Wilderness, there are single runes and combined runes, adding up to millions of runes, which is simply a sea of runes.

Ever since he got the soul rubbings of the Great Wilderness Ancient Tablet Rune, Chen Zheng has been studying every day in combination with the memories passed on to him by Hai Lao, but a few months have passed, and he has only studied less than one ten-thousandth.

He roughly estimated that at his current learning rate, he would not be able to finish his research in a few hundred years.

Although it was quite time-consuming to study the runes, Chen Zheng was still patient and studied them one by one.

Because of this study of runes, when copying runes, he found that his soul power was silently improved, and his control of soul power was becoming more and more accurate.

After these discoveries, Chen Zheng simply began to copy and engrave. Without knowing the name and function of the rune, he used the power of the soul to copy it, and he copied it at a large length. First master the depiction method of these runes, and then study them against Hai Lao's memories.

Four days later, the Black Plains arrived.

The Black Plains are called Black Plains because the soil is black, but when you look at the Black Plains from the sky, they are not black, but green.

The green grass and green trees are endless, which makes people feel refreshed.

Chen Zheng and the others all finished their cultivation and came to the cockpit of the flying boat to enjoy the scenery of the black grassland.

The Black Plains cover an area of 20,000 li, as if it were a green ocean, and a large number of warriors, like schools of fish, swam rapidly in this green ocean.

These warriors come from different directions, but the direction of progress is completely the same, no need to ask, these warriors are all coming to the demon prison that is about to be born.

"Young Master Chen, when we get here, we'd better keep a low profile, otherwise it's very likely that we will be noticed by the Qingyang Sect and cause unnecessary trouble. Lei Yu came to Chen Zheng's side and spoke.

"Hmm!"

Chen Zheng nodded, he understood that at this moment, the super forces such as the Qingyang Sect, the Blood Brake Sect, and the Broken Soul Valley in Zhongzhou must have arrived.

This time he came to the Demon Prison, he was mainly looking for clues to Qinglian's pure soul, and he didn't want to conflict with Qingyang Sect, Blood Brake Gate and Broken Soul Valley.

He pointed to the three or four flying boats in front of him and said, "Let's fly slower and follow behind them." ”

The speed of the Black Dragon Flying Boat slowed down, reducing to a speed similar to that of the other Black Dragon Flying Boats, blending in the middle of the flying boats flying in all directions, and flying towards the hinterland of the Black Plains.

From afar, Chen Zheng saw that in the hinterland of the Black Plains, there were many large and small flying boats, there were thousands of flying boats, and there were countless warriors in the middle, shuttling and busily.

These flying boats are quite scattered, but when viewed from above, they are very regularly enclosed in a huge circle.

In the middle of the circle, there is no grass growing in a radius of ten miles, and it is a swamp.

"Where is the entrance to the Demon Hell?" Looking at the misty swamp, Chen Zheng asked Lei Yu, the sect leader of the Thunder Fist Sect.

Lei Yu nodded, shook his head again, and explained, "The entrance to the Demon Hell will appear there, but it is not the entrance to the Demon Prison. Many people once wanted to enter the Demon Hell to hunt for treasures when the Demon Hell was not open, and they stepped into that swamp, using various methods, even digging three feet into the ground, but they did not find the entrance to the Demon Prison. ”

"So the Demon Prison is not under this swamp?" Lei Yu's words added to the mystery of the Demon Prison, and Chen Zheng asked with great interest.

"It should be!" Lei Yu looked at the black swamp through the window of the Black Dragon Flying Boat and said thoughtfully, "Maybe the Demon Hell is no longer in Zhongzhou, this is just a teleportation array leading to the Demon Hell!"

"Very likely!" Chen Zheng agreed with Lei Yu's inference, thought for a moment, and then asked, "But who set up this teleportation array?"

"I don't know about this!" Lei Yu didn't know much about the Demon Prison, mainly from some ancient records and legends, and many deep-seated things, he naturally didn't know.

The Demon Hell is opened once in 5,000 years, mysterious and abnormal, and there are peerless treasures and the inheritance of the power of the powerful that has long been lost.

Every time the Demon Hell is opened, it will attract a sensation, and countless warriors will rush to come.

What kind of place is the Demon Hell, and who set up the entrance to this Demon Hell?

Those who can set up a teleportation array are probably not ordinary martial artists, at least they should be strong cultivators above the Imperial Martial Realm!

Chen Zheng pondered, the entrance to this demon hell is opened once every five thousand years, is it controlled by someone, or is it automatically opened?

If it is controlled by man, who controls it? What is the purpose of his control? Is it just to let the warriors of the Wild Martial Continent get a chance to hunt for treasure?

The Demon Hell is really a mysterious anomaly!

Chen Zheng sighed secretly, decided to start with the name of the Demon Prison, and asked Lei Yu: "Sect Master Lei, do you know why the Demon Prison is called the Demon Prison?"

"According to the records in ancient books, the Demon Prison did not have a name at the beginning, and the name of the Demon Prison was given by the first batch of warriors who entered the Demon Prison and came out alive. ”

Lei Yu said, his expression sank slightly, as if he remembered something terrible.

"It is said that in the Demon Prison, there is a kind of monster that is different from the demon beast, which has no intelligence, but is extremely ferocious, and specializes in eating human flesh and drinking human blood to constantly evolve, just like the legendary demons. ”

"Warcraft that evolved by eating people?"

Chen Zheng raised his eyebrows slightly, it is not uncommon for demon beasts to eat people, but it is too unbelievable to evolve by eating people.
