Yi Feng and Soul Xuan retreated to the cell just now.

The people of the Purple Cloud Adventure Team hadn't woken up yet, and the red-clothed ones were guarding by the side.

Originally, Yi Feng planned to borrow the road to Purple Cloud City, but he didn't expect him to make a move, but someone made a move against him.

"Yi Feng, are they really okay? Why haven't they woken up yet?"

"Don't worry, they're fine, it's just that their souls are a little weak and they need to rest for a while!"

In another corner of this cell, the Soul Xuanpan sat there, and all the demon souls sealed by Yi Feng were placed in front of him.

Soul Xuan's little face was serious, and he couldn't see the smile he was laughing at all on weekdays.

After taking a deep breath, Soul Xuan raised his arm and began to engrave the mysterious inscriptions, the complexity of the inscriptions, even Yi Feng's current inscription attainments, seemed obscure.

Yi Feng was horrified in his heart, the strength of this soul was still above his imagination!

After a few breaths, a mysterious small array enveloped Yi Feng's sealed demon soul, and at the same time, the demon soul in the soul gourd was also put into the formation by him.

"Soul refining!"

With a low cry from Soul Xuan, a black flame burned in the small array, and for a moment, a howl of pain was heard.

With this kind of scream, even people like Yi Feng had a feeling of numbness on their scalps, and the red clothes not far away had turned pale with fright.

Her gaze at Soul Xuan also changed, she thought he was an ordinary child before, but she didn't expect it to be so terrifying.

This howl lasted for about half a pillar of incense, and the sound became quieter and quieter, and finally disappeared completely.

"Sister Hongyi, you just stay here, no matter what sound you hear, don't go anywhere! I'll go and meet my friends here for a while!"

As soon as the words fell, Yi Feng stepped out and disappeared into the cell.

"You're here later than I thought!"

Yi Feng appeared outside the cell door, looked at the two people opposite, and smiled.

If others don't know, they think it's an old friend meeting!

When Lu Shan and the man in gray saw the guards who were already unconscious, they knew that something had happened here, and the culprit should be the young man in front of them.

"I don't know who your Excellency is, you actually came here to make trouble?"

The man in gray was the first to speak, but the tone of the man in gray surprised Lu Shan on the side.

Lu Shan, who was familiar with the man in gray, was still thinking that the young man in front of him was going to be unlucky, but he never thought that the man in gray was quite polite.

Yi Feng said with a smile: "There is no level in what you are asking, since I am here to make trouble, I am naturally your enemy!"

Yi Feng stared at the man in gray, "Where did you get your demon soul?"

"It seems that you know a lot!" The attitude of the man in gray gradually became cold, no matter how strong this young man is, the more he knows, the more he can't let him live.

"I know more than you think! You got the demon blood from the Death Desert, am I right?"

The gray-clothed man's eyes widened in horror, this was a huge secret of theirs, only a few people knew, and he only knew this secret when he was sent to the Purple Cloud Empire.

Looking at the reaction of the man in gray, Yi Feng knew that he had guessed correctly, the so-called demon blood was really obtained from that terrifying blood pool!

"Since you know so much, no matter what kind of strength you have, I can't leave you behind!" The man in gray had already moved his murderous intent towards Yi Feng!

"What you did to these people in Yunshui City, I can't keep you either!"

The power of the Heavenly Spirit Realm Triple Heaven exploded, and the wind wings behind Yi Feng unfolded, rushing towards the gray-clothed man at an extremely fast speed.

"It turns out that I have some skills, no wonder I dare to come here to make trouble!"

The demonic qi around the gray-clothed man rose, and the momentum of the four heavens of the Heavenly Spirit Realm exploded, and he also swept out at an extremely fast speed, rushing towards Yi Feng.

Bang!

The two of them directly collided with each other, and the violent energy ripples rippled, although Lu Shan, the city lord of Yunshui City, fled in advance, but he was still affected by this terrifying energy wave, and the whole person was swept away, suffering a lot of injuries.

The terrifying extent of the battle between the powerhouses of the Heavenly Spirit Realm can be seen.

The man in gray was secretly frightened, although he suppressed this young man's cultivation of the First Heaven, but the strength of the other party was actually on a par with him!

"It seems that your cultivation level is not enough to suppress me, what about your domain?"

"It's not enough to deal with you, so I can use the domain!" The man in gray swept out again, and the pitch-black demonic qi lingered and gathered on his fist, condensing into the appearance of a fierce beast, and blasted out with a punch, as if a fierce murderer was biting towards Yi Feng.

"It seems that if you don't work harder, you won't use the field!"

Yi Feng's mind moved, and the aura eye behind him appeared, and at this moment, the aura of the entire Yunshui City frantically gathered towards Yi Feng.

His right fist was clenched, thunder and lightning lingered on his fist, and a violent aura spread.

He also rushed towards the man in gray, and this time, Yi Feng still had to fight him.

Rumble!

The collision between thunder and lightning and demonic qi was still between them, and both of them took more than ten steps backwards to stabilize their bodies.

And the area around this cell was affected by the battle between the two.

Lu Shan hid from a distance and watched this battle, cold sweat on his forehead, this young man was too terrifying, he could fight on par with the gray-clothed adult!

If it weren't for the gray-clothed man here, he would have been out of luck.

The man in gray gritted his teeth secretly, but his fists under the cover of demonic qi were trembling slightly, although it seemed that they were on equal footing, but the man in gray knew that he had lost the upper hand both times.

Yi Feng confronted the man in gray, he was not in a hurry to strike again, what he had to do now was to force the man in gray to use the domain.

In the battle with Huang Puxiong, Yi Feng had a new understanding of the field, but he still couldn't fully form his own field.

He needs an opponent who is about the same strength as himself and has a domain to hone it, and this man in gray is the right person right now.

"If you don't use the field yet, it seems that the pressure is not strong enough!"

Yi Feng ran the Ethereal Technique, and the spiritual power in his body ran in a mysterious trajectory for a week, and after fusing with the soul power, his momentum climbed again, and he actually reached the Heavenly Spirit Realm Four Heavens!

The gray-clothed man on the other side widened his eyes, and his shock could not be concealed.

"There is even a secret method to improve your strength?"

The man in gray stepped out, and the pitch-black demonic aura spread out under his feet.

"Heavenly Demon Qi Domain!"

Yi Feng was shrouded in the realm of the man in gray, and he felt that his body was much heavier.

"This realm can actually erode people's bodies, and it can also make people move slowly!"

Yi Feng didn't make any resistance, so he completely exposed himself to the realm of the man in gray, feeling the other party's realm.

The man in gray suddenly appeared in front of Yi Feng, and a palm was imprinted on his chest, so fast that Yi Feng was caught off guard.

Yi Feng's body was bombarded and flew upside down, directly hitting the wall of the cell, knocking down the walls of the cell.

"Didn't you keep telling me to use the realm, and I also used secret methods to improve my strength, and I was so vulnerable!"
