Fortunately, this wave of attack was only for a moment and disappeared after it passed, but Bai Yunfei still felt frightened.

If you are hit directly, you will be seriously injured if not killed.

This virtual sonic attack is many times more powerful than a physical attack.

At this moment, the man dressed as a young master in front of him was implicated by him. He was bleeding from all seven orifices and fell to the ground. However, he was stuffing pills into his mouth at this moment, so it seemed that his life was not in danger.

Bai Yunfei did feel a little apologetic, after all, it was because of him.

This time he slowed down his pace and slowly approached the man.

This person, who had recovered a little, looked at Bai Yunfei. He was first angry, and then he was greatly shocked.

Because at this moment, Bai Yunfei looked almost unaffected, but the corners of his mouth were covered in blood.

Just watched Bai Yunfei walk past.

Bai Yunfei did not say anything and remained silent, but his eyes showed an apologetic look towards this person.

The two men passed each other and Bai Yunfei continued to move forward.

Looking at Bai Yunfei leaving, the warrior dressed as a young master had a hint of expectation, but did not follow him.

Bai Yunfei's mental power naturally noticed this.

There were still a few people on this passage, but they were moving more slowly for fear of causing any noise.

Everyone remained alert to Bai Yunfei who was passing by.

After investigating with spiritual power, it was discovered that these people were extremely powerful, much stronger than those at the peak of the Spiritual Martial Realm. It was estimated that they might have reached the Half-Step Sky Control Realm.

After being surprised, I understood that anyone who could walk so far in Echo Valley must not be an ordinary person.

After reaching the end of the passage, Bai Yunfei had spent a total of half a day.

After turning a corner, the view in front of me suddenly opened up.

It looked like the place was full of birdsong and flowers, with all kinds of trees and flowers. However, after using mental power to investigate, not a single flying bird was found, and there were almost no insects or the like.

No, after using spiritual power to detect a location several dozen feet away, an ice silkworm the size of a thumb was found on a mulberry tree.

His entire body was snow-white, and he carried a chill that could be felt even if one approached it with spiritual power.

It seems that this is the so-called ice silkworm, but it is really too small.

Then this mulberry tree is the ice silkworm leaf.

The leaves are emerald green, with a fluctuation of life. After the spiritual power penetrates into them, there is a warmth and comfort.

The corner was about thirty feet away from the mulberry tree, but Bai Yunfei had a feeling of extreme danger.

After trying to take a step, it was as if he had passed through a layer of membrane that he could not look directly at, but a wave of nothingness immediately invaded that leg.

Nothing can be seen on the surface, but the fluctuations make the blood riot, and the blood vessels feel as if they are bursting, as if even the tiniest particles are boiling.

The body is severely damaged from the inside out.

Bai Yunfei quickly retracted his legs.

The world inside was filled with terrifying sound waves. Even if no sound was emitted, these invisible sound waves were always there, like a kind of protection.

This kind of mulberry leaves have an inhibitory effect on Jiuchongxiao's poison. Jiuchongxiao probably knows this, but at the moment there is no one from Jiuchongxiao stationed here. It can be seen that he still has full confidence in Echo Valley.

After all, this poison only works on people below the sky. It is almost impossible for people below the sky to enter the Echo Valley.

At a distance of thirty feet, Bai Yunfei felt a sense of despair.

His physical strength was only slightly lower than that of the Sky Control Realm, but even so, he did not dare to enter.

This is just the legs. If the body enters, the head and the inside of the body will probably collapse in just one blow.

Even those at the Sky Control Realm probably wouldn’t be able to hold out for a few breaths.

However, unless you can fly in the air, it is impossible to completely judge whether the sky-controlling realm has any special means.

However, Bai Yunfei judged that it would be difficult for ordinary people to control the sky.

Looking at the ice silkworm leaves inside, he seemed a little helpless at the moment.

I really don’t dare to go in!

After thinking for a long time, his eyes lit up and it seemed that he could give it a try.

The ancient flying sword shot out from the sea of ​​consciousness and shot straight into the valley.

The speed was very slow. When the flying sword entered, countless invisible energies began to attack the flying sword. Bai Yunfei felt it clearly, but the flying sword had no problems at all and not even a trace of vibration.

There is no wrong version in the 1619 book forum!

Bai Yunfei gained confidence and controlled the flying sword. He flew to the branch where the ice silkworm was and chopped it down directly.

A piece of branch fell down with a sound, carrying the ice silkworm with it and dropped directly to the ground.

The entire valley seemed to shake, and the invisible waves caused an earthquake-like shake.

Inside the valley, the void was shaking violently, and Bai Yunfei's eyes were in a trance.

After a full moment, the astonishing changes inside completely disappeared.

Bai Yunfei broke out in a cold sweat and was quite worried.

This place is really too weird.

The flying sword has returned.

Bai Yunfei searched in the space and actually found a piece of rope, which was several dozen feet long.

This can be considered as an essential item for warriors, and should be possessed by the sword spirit of the Tiandao Sect.

The rope was made of a mixture of gold wire and an unknown substance and was extremely tough.

One end was tied to the flying sword and began to slowly enter it.

However, after entering it, the attack of nothingness enveloped the rope.

After trembling a few times, Bai Yunfei breathed a sigh of relief. Fortunately, he held on.

The movements were extremely slow. After reaching the branch, he controlled the flying sword and wrapped the rope around it.

He was outside and began to pull the rope.

But the movements were extremely gentle, because every time it was pulled, there would be sounds of wind and thunder in the valley, and the void would seem to collapse with terror.

The extremely tough rope was actually broken.

I was anxious, but there was nothing I could do but pull the rope slowly.

It took two full hours to reach ten feet. Bai Yunfei's forehead was covered with sweat and he was very nervous.

At this moment, the rope that led into the valley broke completely at the root. The part inside the valley seemed to be turned into ashes, destroyed by an unknown energy.

Bai Yunfei trembled, and his movement was not stopped. His body actually took a step back, but a slight sound was made.
