In the direction of the south of the city of Yuhai City, there is a secluded place here.

This area is heavily guarded, and the black fog inside is filled all the year round, and it is hazy and unreal, as if it is independent from the world, and it is incompatible with the entire Yuhai City.

In the meantime, there were constantly soldiers wearing treasure armor and holding clear guns patrolling back and forth, and a powerful aura constantly scanned the entire area, and the tall walls were densely covered with bows and crossbows, ready to buckle the strings at any time.

Yan Yuncheng stood in the distance, looking at this area with a solemn expression, this area is where the Sea Clan and the most vicious people are imprisoned in the Royal Sea City, the people of the Royal Sea City call it the Sea Demon Hell, if you enter it, don't want to see the light of day again, and Hai Linyu is now imprisoned inside, and he doesn't know whether he is alive or dead.

Dian Xiaoer also got the news from elsewhere, only knowing that Hai Linyu was imprisoned in the Sea Demon Hell by King Pinghai, but the specific reason was unknown.

The Sea Demon Hell was unusually well defended, and it was even more difficult to sneak in than to ascend to the sky, and Yan Yuncheng couldn't think of any way to sneak in for a while.

It's night.

Yan Yuncheng had been wandering around not far from the Sea Demon Hell Prison, and he wanted to take advantage of the time when the soldiers changed their guards, looking for an opportunity to sneak in, but to his disappointment, the Sea Demon Hell Soldiers did a good job of changing their guards, and there was no chance at all.

Just when Yan Yuncheng had nothing to do in his heart, his powerful spiritual sense suddenly sensed that there were several powerful auras, and he was rushing towards the Sea Demon Hell like a lightning speed, and he hurriedly held his breath to restrain the aura of his whole body.

"Bang!"

I saw several spiritual powers piercing the night, like brilliant fireworks, and suddenly fell on the gate of the Sea Demon Hell Hell, and the huge fine iron gate of the Sea Demon Hell instantly turned into powder, and at the same time, the alarm bell in the Sea Demon Hell rang loudly, and the huge sound spread throughout the entire Sea City like a wave.

"What did I hear?"

"The sound of the hellbells of the Sea Devil?"

"Why does it ring?"

All the people in Yuhai City who heard the bell were stunned, and then all kinds of shocking voices rang out.

In front of the fine iron gate, several figures shrouded in black fog stepped into the air, and the powerful aura of the Dragon Transformation Realm was unconcealed, roaring and raging like a raging wave, and the thunder crossbow on the high wall did not hesitate, and suddenly the fire was fully opened, and the spiritual arrows in the sky fell like a shower.

The few people shrouded in the black mist were not afraid, the spiritual power on their bodies surged, and they simply swung out with a palm and a fist, and the crossbow arrows suddenly burst in the air, and the dazzling light of the spiritual explosion reflected the entire night sky as bright as day.

"What a bold man, he dared to attack the Sea Demon Hell and die!"

In the Sea Demon Hell, several powerful breaths that Yan Yun City had previously sensed suddenly erupted, only to see several extreme white lights breaking through the air from the Sea Demon Hell, and in the blink of an eye, several figures appeared in front of the gate of the Sea Demon Hell, confronting everyone who came to attack the Sea Demon Hell, and the aura on everyone's body was deep, like an abyss and the sea.

The two sides didn't talk nonsense at all, and as soon as they looked at each other, they were killed, and the large number of high walls and buildings instantly turned into ashes, dissipating in the air without a trace, and the fire began to spread from the gate of the Sea Demon Hell to all directions, and soon turned into a prairie fire, and the ground was bombarded into a pit more than ten zhang deep.

There is no doubt about the horror of the destructive power of the masters of the Dragon Transformation Realm, and the masters in the Sea Demon Hell are constantly trying to force the enemy into the air, but the enemy seems to know what they are thinking, and desperately attacks the Sea Demon Hell Hell, and more and more places are bombed into powder and turned into ruins.

The furious energy pushed horizontally in all directions, and everything that stood in the way on the ground instantly turned into nothingness, and within a radius of ten miles, it suddenly turned into ruins, and this ruin continued to expand as several people fought.

The movement of the Sea Demon Hell alarmed the entire Imperial Sea City, and people kept rushing towards this side, wanting to take a peek at it, more and more people rushed to come, and the Sea Demon Hell defenders had no choice but to completely block this place, even if this could not eliminate everyone's curiosity, more and more people gathered in a cloud, and everyone had a shocked look on their faces.

"Who are they who dare to rob the prison?"

"It's like hitting a stone with an egg, and you dare to run to Yuhai City to spread wild!"

"I really admire these people, they are brave enough!"

"Awesome my Black Mist Man!"

......

The onlookers began to discuss, no wonder everyone was shocked, this Sea Demon Hell has existed since the establishment of the Sea City thousands of years ago, and for thousands of years, the Sea Demon Hell has detained many Sea Clansmen, as well as the most vicious people, and there has never been a prison robbery, let alone such a large-scale attack on the Sea Siren Hell Prison.

After a few breaths, the master in the Sea Demon Prison controlled the situation and constantly suppressed the enemy, and the enemy had to retreat.

Seeing that the general trend had gone, the enemy no longer competed with the masters in the Sea Demon Hell, but turned the target and frantically sabotage, shot at the surrounding crowd, blocked the surrounding city guards, and those who rushed over to see the excitement were suddenly attacked.

The cultivation of the Dragon Realm was terrifying, and the outside of the Sea Demon Hell suddenly turned into the Shura Hell, screaming and howling one after another, making the scalp numb, and in an instant, the surrounding bodies were floating all over the ground, and the blood flowed like a river, and the entire Sea Demon Hell became a pot of porridge.

Yan Yuncheng sensed the powerful aura of several people, and immediately fled far enough away, so he did not receive any harm when the enemy made a vicious attack.

He was shocked in his heart, not only did someone dare to attack the Sea Demon Hell, slaughtering onlookers, but it was too coincidental, he was suffering from not being able to blend into the Sea Demon Hell, and it just so happened that the once-in-a-millennium attack on the Sea Demon Heller came, so that he could have the opportunity to blend into this Sea Demon Hell.

Taking advantage of the chaos, the Nebula Divine Technique at the foot of Yanyun City was operating to the extreme, although the Sea Demon Hell was being attacked at the moment, its defense was still solid, but after all, the movement outside attracted the attention of most people, and he was able to sneak into the Sea Demon Hell without danger.

A small part of the Sea Demon Hell was destroyed at the front end, and the buildings in the depths were scarce, still calm as water, as it continued to go deeper, the Sea Demon Hell was always dark, although it was already in the middle of the moon, but the moonlight seemed to have forgotten here, and the slightest moonlight fell, but it was strangely dissipated, or swallowed.

Yan Yuncheng didn't know what the situation was like in the Sea Demon Hell at all, he had to run around like a headless fly, and he had to be on guard at all times for soldiers patrolling back and forth, and there were still people with a powerful aura lurking in the unknown depths, constantly scanning back and forth.

The longer he lingered, the stronger Yan Yuncheng found that the Sea Demon Hell gave him a stronger sense of depression, at this time, the night in the Sea Demon Hell was like a dormant ancient beast, as if he would be devoured in the next moment, and the chill on his body became deeper and deeper, and this depth was not only a physical perception, but also a spiritual soul.

The cultivation of Yanyun City's psychic realm should be regarded as day in the dark night, but he found that the longer he stayed here, the shorter the distance that could be seen by the naked eye became shorter and shorter, and his spiritual perception was gradually lost.

If he continued to look for it so aimlessly, Yan Yuncheng knew that it would not lead to anything, so he jumped on the top of a house at the moment, looked into the distance, and found a clue in his right hand.

Yan Yun City's spiritual sense spread, and he wanted to explore, but the spiritual sense couldn't extend beyond ten zhang at all, so he had to give up, but there seemed to be a towering shadow in that direction, rather than wasting time in vain, it was better to go and find out.

He used the Nebula Divine Technique, and found that even the spiritual power in his body seemed to have become sluggish, and the closer he got to the towering shadow, the more obvious this situation became, and soon the spiritual power in Yan Yun City's body was like ice, unable to mobilize the slightest, and he now became no different from ordinary people.

Unable to use his spiritual power, Yan Yuncheng had to rely on the power of his body to start running in the Sea Demon Hell, but the towering shadow seemed to be in the endless place of heaven and earth, no matter how Yan Yuncheng ran, he couldn't get close to a fraction, but was getting farther and farther away from him.

"How so?"

Yan Yuncheng was suspicious in his heart, he wanted to ask Goudan, but he found that the power of the divine soul was also imprisoned, and he couldn't get in touch with Goudan, everything had to rely on himself.

At that moment, he stopped running, and his originally restless mood slowly calmed down, and his mind continued to connect all kinds of strange places he saw when he entered this place, trying to find clues from them and crack the ghosts of this place.

The possibility of the existence of the source field here was directly expelled by Yanyun City, these days he has been studying the source technique in the Xuanpan, and his understanding of the source field has become more and more profound, he can't feel the slightest fluctuation of the situation in heaven and earth here, so he can be very sure that this is not the source field.

Since this place was not caused by the source field, how could such a strange scene appear? Yan Yuncheng was puzzled, standing in place and pacing back and forth, his hands unconsciously rubbing back and forth.

"Hmm!"

Yan Yuncheng suddenly froze, and his mouth was shocked.

"The palms, the backs of the hands, the yin, the yang, the positive, the negative..."

Yan Yuncheng suddenly had a flash of inspiration, as if he had caught something, and muttered to himself, as if he had found something, and exclaimed.

He turned around and ran in the direction of the towering shadows, and after running a long enough distance, Yan Yuncheng turned around and looked back at the towering shadows, and the shadows were actually closer to him again.

Yan Yuncheng continued to run in the opposite direction of the shadows, and after half an hour of galloping, a towering shadow appeared in his eyes, and a towering shadow could also be seen behind him, and the two shadows stood opposite each other and reflected each other.

"Sure enough, I know, it's amazing!"

Yan Yuncheng's conjecture was confirmed, when he inadvertently rubbed his palm, he suddenly noticed that the hand is divided into the palm and the back, the two are positive and negative, that is, the so-called one yin and one yang, if the change of yin and yang is used here, although there are similarities, but there is always something missing, this is the towering shadow that runs farther and farther away.
