"I'm coming!" At this time, the cold man who had been standing behind him silently suddenly spoke.

When I opened my backpack, it was filled with some mountaineering equipment.

A bundle of strings, after the cold man fixed it, holding a submachine gun, said lightly: "You wait!" ”

Just a sentence, he grabbed the rope and jumped down.

A few seconds later, a series of gunshots rang out, accompanied by the screams of a grim man, causing everyone to look at each other.

Ren Chunxue was even more disdainful: "What do you say this guy is doing when he has nothing to do, looking for death?" ”

"He's not dead." Liu Mu shook his head, his face was still solemn, "This black hole is in the shape of a sharp cone, the further down the space, the bigger the space, when that kid went down just now, there were some humanoid creatures similar to bats on the rock wall, the speed was fast, it should be a relationship with light, and these creatures attacked the cold man one after another." ”

"None of them are dead?" Li Bo asked in surprise, but then realized something and immediately covered his mouth again.

"Although the cold man doesn't speak, he is very fast and has extremely accurate marksmanship, although he was slightly injured, but it is not a big deal." Liu Mu glanced at Li Bo, and then said lightly, "There are only a dozen of those humanoid creatures, and they can't pose any threat to him." ”

"Jingle Bell ......"

At this moment, the bell on the rope rang, and Liu Mu immediately said, "There is no problem now, let's all go down first." ”

As he spoke, he jumped down directly in free fall, twin brothers, Ren Chunxue followed, only Li Bo and Sun Zhenggen glanced at each other, and then slowly went down through the rope......

The four of them landed, but they were stunned: "It's only more than 100 meters deep?" ”

"Ahead, there's a revolving ladder." The cold man was tending to the wound at this time, and pointed ahead.

The twin brothers adapted to the light inside, and couldn't help but gasp: "It's actually a ladder chiseled into the wall, densely packed, extending downward, at least tens of thousands of steps, right?!" ”

"Probably more." Liu Mu said a word, and waved his big hand at the cold man, and the purple true qi attached to the cold man's wound, and immediately, the cold man felt that the wound was healing at a speed visible to the naked eye, but in more than ten seconds, the injury just now disappeared like this!

This made the cold man look at Liu Mu in surprise, no wonder he would choose to make him everyone's captain, it was really extraordinary!

"It's the first time I've been to this kind of place, and it looks a little surprising!" At this time, Sun Zhenggen and the others had already come down, looking at the bottomless steps below, and swallowed unconsciously, "I don't know how deep it is below." ”

"At least a thousand meters." Liu Mu said in a deep voice, "Vertically down, the steps are so tight, it looks like there should be 100,000 steps, if we take the steps, we won't be able to go down for a while!" ”

"Or vertically down?" The cold man couldn't help but ask.

"For now, it seems that this is the only way." Liu Mu nodded, "This time, I'll go first, you wait for my signal!" ”

Without waiting for the six people to say more, they had already jumped down first, and at the same time, the true qi on his body formed a small shield within three meters of the surrounding area, in order to avoid unnecessary danger.

Slowly descending, it looks like an ordinary rotating staircase, nothing special.

However, this was just Liu Mu's idea before the two hundred meters, and as Liu Mu entered the two hundred meters, an unknown pressure suddenly appeared in his heart, and this pressure came from all directions, and it was unknown where it emanated!

"Woo Woo ......"

More than ten seconds later, a burst of bows and crossbows suddenly came from all directions, the density was extremely high, almost six rounds per flat rice, and it was an indiscriminate attack, and it was not aimed at Liu Mu.

"The early stage of Jindan?" Although this didn't do any harm to Liu Mu, he was still a little surprised when he felt the power of the crossbow arrow.

If it's just one or two, it's just that, but now it's a sky full of crossbow arrows, all of which are the attack power of the early stage of Jindan, and the guy who designed this mechanism is at least at the peak of Yuanying, or even in the distraction period, otherwise it is impossible to arrange it!

"At a depth of a hundred meters, there must be at least hundreds of thousands of crossbow arrows just now!" After descending to more than 300 meters, the crossbow bolt mechanism finally disappeared, but Liu Mu did not take it lightly.

The point is that the stone wall is full of small holes in the code code, and these crossbow arrows are shot from one wall to another, and directly enter the small holes, which is equivalent to the crossbow arrows being fired and immediately recycled.

"Miasma?!" Just thinking about it, Liu Mu was suddenly stunned, only to find that he had just inhaled a breath of miasma in his nose, although it didn't cause him any harm, but when he felt it carefully, he was still a little dizzy, these poisonous miasma were really powerful, if he were an ordinary person like Li Bo, it was estimated that he would directly turn into water!

The most shocking thing is that these poisonous miasma are actually immune to true qi, although Liu Mu turned the surrounding three meters into a vacuum, but the poisonous miasma still penetrated in!

In the next few hundred meters, basically all of them were this poisonous miasma, and the further down they went, the more and more they knew, and after knowing that after eight hundred meters, the poisonous miasma finally disappeared, and from then on, until the flat ground, there was no longer any mechanism.

"It's just this part of the road, it is estimated that under the middle of the Yuan Infant, there is no one who can come down at all!" Liu Mu shook his head slightly, thought about it, his figure flashed, and rushed back again.

"How?" The six people above were a little bored waiting, and when they saw Liu Mu coming back, they immediately asked.

"There are a hundred meters below, all of them are very dense crossbow arrow attacks, and the power of each crossbow arrow has the power of the early stage of Jindan!" Liu Mu shook his head slightly, "Further down, it is a miasma that is not afraid of true qi, it is extremely poisonous, and it can turn ordinary people into water!" ”

"What then?!" Hearing this, Li Bo was stunned at that time.

"Before I came, my country's most powerful invention expert gave me a few defensive balls, he said that it can defend against attacks from the strength of the cultivation realm at least the mid-stage of Jindan, and it is insulated from the outside world, and it has its own oxygen inside, and we can use this defense machine to go inside." As he spoke, the cold man took out a glass marble-sized glass ball from his pocket, and then threw it on the ground, immediately becoming extremely large, almost able to hold ten people.

"Is there such an amazing thing?" Li Bo laughed, looked at one of the entrances, and went straight in.

"Just go in and go in." The cold man nodded.

While lamenting the magic of science and technology, Liu Mu was the last to score the ball.

I saw that under the operation of the cold man, the ball closed, forming a complete sphere, and then the cold man hugged it, and the ball fell directly down......
