Han Feng spread out his soul power and probed forward, but was stopped by a strange force, spreading to the outskirts of Alcatraz Island for three hundred miles, and then stopped, unable to advance forward.

He could only give up, and while he still had some time to spare before the time limit set for him by the mysterious organization, he flew into the sky, hid in a white cloud, and ran the alchemy vajra technique to completely restrain his breath. Then, he took out several bottles of various pills and took them, silently refining the medicinal power to restore his state to the best.

After a short time, people flew in from the rear one after another, all of them were Jiedan monks, and most of them were in groups, only a few monks came alone like Han Feng.

Such characters are naturally advanced in cultivation, at least at the level of the later stage of the Jiedan, and there is even no shortage of great monks who have completed the Yudan.

Not only on the side where Han Feng was, but there was also an endless stream of people rushing over from other directions, but for most of the hour, hundreds of people had gathered in this sea area.

The group of them came from all directions, but they didn't rush into Alcatraz Island, and their faces showed a little solemnity, suspended in the air, and stopped.

However, each of them was limited by the time constraints of the mysterious organization, and after another cup of tea, some had to fly forward.

Soon, a group of more than a dozen people entered the ink-like sea, their bodies suddenly froze, as if they were pulled by some force, their speed dropped significantly, and the more they flew towards Alcatraz Island, the slower their speed became.

Han Feng's eyes flashed, he paid close attention to their movements, and after waiting for so long, he just wanted to let these people go over and explore the way first.

At present, it seems that there is no other danger in that ink-like sea area, it should be that there is a silent field power that imprisons their bodies, which is why their speed has dropped so much.

Calculating the time, Han Feng was almost at the end of the deadline, he didn't dare to confront the mysterious organization that was backed by the Feather Immortal Sect, so he could only swoop down honestly and rush into that sea area.

Sure enough, bursts of strange power enveloped his body, but it did not just rush up from below, but surged from all directions, like an invisible giant hand to hold him tightly, if ordinary monks came in, they would have to turn into a cloud of blood mist.

Han Feng secretly estimated that if he wanted to resist this force, he would need to at least reach the cultivation of the Yudan realm.

It's no wonder that the mysterious organization of the Feather Immortal Sect only asked the monks of the Yudan Realm to help them complete this task, it turned out that it was because of the strange power in this sea area.

Moreover, there were many difficulties along the way, and without any strength, they would have died halfway through, after all, the passage opened by the Feather Immortal Sect could not directly teleport them here, and they had to rely on their own strength.

At this moment, Han Feng was suppressed by this force, but he was not as unbearable as the group of people just now, and under the flickering golden light all over his body, he struggled, but he did not start his speed, he just flew through the air, only stepped a distance of dozens of zhang in one step, and slowly followed behind those people, waiting for the changes.

The more he flew into the depths of this sea area, the stronger the resistance became, and Han Feng gradually felt the pressure, without the relaxed freehand at the beginning, he simply put on a dignified look, and still hung behind the first batch of people not far away, the purpose was naturally self-evident, that is, to ask them to help take the lead.

This group of people is not stupid, when they found that Han Feng was doing this, some of the people who were weaker in cultivation naturally dared not speak out, but some monks immediately turned around and looked him up and down.

A middle-aged round-faced man in the late stage of the Jiedan even glanced at Han Feng coldly, snorted slightly, and said indifferently: "This fellow Daoist, why don't you hurry up and come over with us, you have committed a big taboo by doing this, aren't you afraid of causing public anger?"

If Han Feng didn't hear it, he didn't pay attention to this person at all, and floated forward by himself.

"Are you deaf? Don't you hear me?!" The middle-aged man was furious, turned sideways, raised his hand and waved, shooting out a large dark green light, and roared towards Han Feng.

Han Feng flicked his hand casually, and the blue light came out like a wall, and in an instant, he crushed the opponent's attack, and counterattacked, transforming into a green dragon and devouring the opponent.

The middle-aged man's face changed, one hand was raised, and a spear appeared in his hand out of thin air, dancing in an instant, and in the burst of green light, thousands of giant pythons condensed out, fighting with the green dragon endlessly.

However, after only a short while, these turquoise pythons collapsed, dissolved, and completely annihilated under the rampage of the green dragon, and there was nothing left.

The middle-aged man's face turned pale, and he tried his best to continuously give birth to more emerald pythons, but he couldn't crack Han Feng's green dragon, but was approached by it more and more, and he had the potential to be swallowed by it in one bite.

"Seniors spare their lives!" the man suddenly came to his senses and hurriedly shouted.

Han Feng didn't care about it, he didn't show the slightest sign of stopping the attack, but instead stretched out his hand and pointed again, a line of streamer flew out, faintly surrounded by sword aura, and it was invincible, breaking the opponent's emerald python in one go, ignoring the defense on the surface of his body, shooting a hole in his left arm, the wound was extremely smooth, and there was no blood at all.

This person's face was pale, and he didn't know whether he was injured or frightened, and he was stunned on the spot for a while, but he was also a clever person, and he quickly came back to his senses, endured the severe pain, clasped his fists at Han Feng, and saluted respectfully: "Thank you seniors for your mercy!"

Han Feng stopped, glanced at him, and continued to fly forward.

The middle-aged man had palpitations, his eyes rolled, and he hurriedly continued to fly forward, as if he also understood Han Feng's intentions, as if he was working hard, and his speed was three points faster.

Seeing this, the rest of the monks did not dare to stay, and flew with all their might, approaching Alcatraz Island more and more.

At this moment, this sea area began to surge without warning, bursts of black qi emerged, and the power of imprisonment became greater, and some monks in the early stage of the knot had to resist with the help of magic weapons.

Han Feng sensed that an inexplicable magic circle was operating, imprisoning this area, and the closer he got to Alcatraz Island, the more powerful it became, as if the space was frozen.

At the same time, he looked at the black qi coming out of the sea, silently identified it, and found that it was familiar, if he didn't guess wrong, it should be demonic qi, but the purity was naturally not as good as those demonic origin qi that he had encountered before.

"Could it be that this invisible magic circle is used to imprison demonic qi? The stronger the magic circle, the greater the resistance of demonic qi, so there will be a scene of sea water surging and demonic qi overflowing?" Han Feng's mind was racing, and he secretly guessed.
