The cave was pitch black, and Xia Fan, who was walking in the front, condensed the vitality on the surface of his body, illuminating it through the light emitted by the vitality itself.

Others followed suit, condensing their vitality on the surface of their bodies and illuminating their surroundings.

But even so, the whole cave still feels quite eerie.

The cave is not narrow enough to accommodate five or six people in parallel, but if they are too close to each other, it will obviously affect each other's reflexes and flexibility, and in case of emergencies, it will cause a lot of obstacles to each other.

Therefore, the blood servants are a little separated from each other, making the whole team longer.

After entering the cave, just after walking less than two or three thousand meters away, a fork in the road appeared in front of everyone's eyes, Xia Fan took everyone directly along the fork on the right to enter, and continued to move forward for a distance of two or three thousand meters, and once again a fork in the eyes of everyone......

Just like that, all the way forward, the forks kept appearing, Xia Fan was moving forward left or right without interruption, after half a day passed, the forks that everyone passed through had reached dozens of them!

And these forks are separated from each other at almost exactly the same angle, and even the most careful observer can hardly tell any difference from the appearance of the fork in the road!

Even if you turn around and walk back now, the fork in the road you encounter will be basically the same as what you saw when you came!

This also means that if a person who does not know the route rushes in, then it is very likely that under the influence of this fork in the road, he will get lost in it directly, and he will not be able to get out for the rest of his life......

"Sir, this ...... Is this artificially excavated? It's scary, isn't it? How big is this labyrinth? And...... Does it make sense to do such a maze? Not to mention the time and effort...... If it's really a strong man who breaks in and gets lost, it's a big deal to bombard the mountain directly, and you can always get out sooner or later......"

Bai Xingshu, who had always followed Xia Fan, said with a embarrassed expression.

"It was made by the Bloody Hand Organization, but I don't know how it was made. As for what you said about bombarding the mountain upwards...... You can now try punching the walls on both sides. Friendly reminder, don't use too much force. ”

Xia Fan turned around and smiled at Bai Xingshu.

Bai Xingshu was a little puzzled, reached out and touched the cave wall beside him, and then punched him curiously.

But Xia Fan reminded him that Bai Xingshu's punch used three points of force, even so, if it was just an ordinary cave wall, Bai Xingshu's punch would be enough to collapse a considerable part of the cave wall.

However, when Bai Xingshu's fist really slammed into the cave wall, the violent sound that everyone expected did not appear.

On the contrary, Bai Xingshu's face changed slightly, and the whole person suddenly took three steps back and 'kicked and kicked', and the arm that hit the cave wall was directly bounced back.

The breath surged, and it took a few breaths to barely suppress it.

"What's wrong?!"

Yan Zi'an, who was closest to Bai Xingshu, couldn't help but ask.

"This ...... This cave wall can actually bounce my power! ”

Bai Xingshu had an incredible expression on his face.

"The headquarters of the Bloody Hand is actually all shrouded in a huge rune formation, and the same is true of this cave labyrinth. Even a strong person at the supreme level of martial arts, in this cave maze, must completely follow the rules of the cave maze, and if you want to destroy the cave maze in a violent way, it will not work at all. It is said that the highest level of power that this rune formation can limit can reach the level of the peak of the transcendent realm, and unless it is a saint, it is impossible to break through the limit of this rune formation. ”

Xia Fan's voice reached everyone's ears.

"Only by reaching the saints can you be unrestricted?"

Bai Xingshu looked at Xia Fan in amazement.

"That's right, I was also puzzled at first, but since I met that Sikong Saint before, many things can be thought out smoothly. This rune formation is not something from the outer realm at all, but from the inner domain. The power it should possess is obviously stronger than what it is showing now, but it is limited by the concentration of vitality in the outer realm, and it can only show such a level that is limited to the saints. ”

Xia Fan opened his mouth to explain.

"It's scary......"

The Blood Attendants looked at each other for a moment.

"Okay, let's move on, we've almost walked about two-thirds of the way, and after another one-third or so, we can really enter the headquarters of the Black Hand Organization."

Xia Fan raised his hand and walked forward again.

"It's only two-thirds of the way through? Master, how big is this cave labyrinth? When I looked at the broken wall outside, I didn't feel that big......"

One of the Blood Squires couldn't help but ask.

"Since we entered the cave, in fact, this cave has always had an inconspicuous downward arc, and after walking for so long, do you think we are still on the ground? Don't be stupid, you've already gone around to a depth of at least 100 meters underground. Fifty meters or so further down is almost the headquarters of the Black Hand. An incredibly large underground space. ”

Xia Fan said without looking back.

The crowd looked at each other again.

For a while, it was a bit amazing that the Black Hand Organization was able to build such a headquarters.

After several more hours of walking, only about half the distance of the previous road after entering the last forked cavern, a corner suddenly appeared.

Turning this corner, everyone's eyes finally opened up.

A huge cave that looks like it is at least tens of thousands of square meters in size and more than ten meters high is presented in front of everyone's eyes.

The cave was so empty that you could see it, and nothing was there, but even though there was not a single crevice that could be used for light, the cave was as bright as day.

Every inch of the cave wall seemed to glow.

"If you enter the headquarters normally, someone will come here to answer you, and then open a secret door with a unique identity verification method and bring visitors in. But none of us can do that kind of authentication, so the only way to open the secret door is to break the ban here. “

After everyone walked into this empty cave, Xia Fan spoke.

"Forbidden? What is forbidden? ”

Bai Xingshu took a mouthful.

Before the words could be spoken, the light in the cave wall suddenly began to flicker.

Immediately after that, everyone heard a strange noise at the same time!

Everyone was subconsciously vigilant, but Xia Fan raised his head.

Originally, everyone was headed by Xia Fan, and they naturally paid attention to Xia Fan's actions at all times, and after seeing Xia Fan raise his head, others also instinctively raised their heads.

But what I saw next made everyone a little stunned for a while.

Because above the head, the top of the cave, which is more than ten meters high, is slowly sinking!
