Everyone gritted their teeth like this and persevered, and walked forward for dozens of meters, not only did not relieve the pain, but intensified it. The passages became narrower, and the air became thinner.

On the monitor on the wrist, it shows that the outside air is not suitable for breathing, the content of harmful substances in it is too high, and warning symbols have been appearing, and everyone has already turned on the respirator on the helmet.

The backpacks behind the female warriors had long been lowered and pushed on the ground, otherwise they would not have been able to move forward.

The cramped space, the terrible air, the enveloped darkness, these are intertwined, tormenting these intruding strangers......

Suddenly, the West Pole Twilight Snow at the front used the public channel and excitedly said: "There is a shaft in front of me, we can continue to go down!" ”

This news shocked everyone's spirits, and they sped up the speed of crawling.

And Zhang Xiaohu crawled for more than 20 minutes in the second half of the large army before reaching a wide place. Here, the passage becomes about two or three meters high, like a large room. In the middle of the room, there is a shaft.

The shaft is surrounded by cyan boulders, and a silver tripod is erected at the mouth of the shaft. There were four warriors standing around, who were helping the people behind them to get down into the well.

King Peter in front of Zhang Xiaohu had already begun to slide down the rope and downward. Looking at his expression, he seems to be quite relaxed. After Zhang Xiaohu got out of the passage, he felt that the space was wide, and he wanted to stand up and walk to the side of the shaft, but his two legs were very useless, and he couldn't stand up because he was weak. He simply gave up this idea, crawled over honestly, and then slowly descended into the darkness below with the help of the female warriors.

There are a total of five ropes tied to his body, the one on his chest is responsible for controlling the descent speed, the two under his armpits are for stabilizing his body, and the two on his back are two safety ropes to ensure that he will not have other accidents.

The shaft was carved out of solid rock, and the dragons must have put a lot of effort into it.

"Rustle ......" Zhang Xiaohu's watch, a green light flashed, this is someone connecting to his channel. He opened the call settings, and Zhao Zixuan's voice immediately rang.

"Lao Zhang, are you down there?"

"Hmmm! I'm in front of you, what do you do when you contact me at this time? Zhang Xiaohu was puzzled.

"I'm telling you, the mechanism they placed just now was touched, and I just felt the whole mountain tremble!"

"Why didn't I feel it!" Zhang Xiaohu said, looking at the portrait, the top of his head was pitch black, and he could only see a trembling orange light in the distance. Other than that, there is nothing else.

"Lao Zhao, then you should be careful in the back!" Zhang Xiaohu instructed, and at the same time, the green light on his watch was lit again, who is it? He thought, and quickly connected the call, and the voice of the West Pole rang out again.

"Zhang Xiaohu, where are you going?" A map of the secret passages automatically popped up at the watch, and in the straight shafts, everyone's positions were scattered at various heights, with the people at the bottom almost reaching the bottom, and some still at the mouth of the well.

"Commander-in-chief, I'm in a third of the position now!" Zhang Xiaohu found the signal point marked with his identity from the map and reported his location.

"Speed up! There's trouble up there! Nishiji commanded in a deep voice and hung up the call randomly.

Zhang Xiaohu had no choice but to speed up the descent, and at the same time, he found that on the map, the descent speed of other people also became faster. He looked at the location of the wellhead, and noticed that the few points of light that had gathered at the top had suddenly disappeared at the same time.

This is not a good signal, the soldiers of the Sacrifice Legion who remain above must be broken, they are cut off to protect everyone's safety, so they will definitely not deliberately turn off their signal, there must be some accident.

Judging from the map, Zhang Xiaohu has dropped two-thirds of the distance, and there will be a few hundred meters below to the end, and above him, there are about 25 or so points of light, and he found that in addition to a few people at the wellhead just now, the signal at the top of the shaft began to disappear again.

"Everyone, open the safety rope and free fall!" Xiji's voice suddenly sounded rapidly from the public channel.

Zhang Xiaohu was hesitating whether to untie the safety rope immediately, and suddenly a heavy object fell on his body, which turned out to be the corpse of a female soldier of the Sacrifice Legion, and the scattered brown blood splashed on Zhang Xiaohu's mask, he suddenly couldn't see the situation outside, he used his hand in a panic to wipe the filth off the helmet, and before he had time to check the body hanging on his body, he felt his body sink again.

"Who's down there, let's go...... Ah......" It turned out to be Zhao Zixuan's voice sounding from the public channel.

"Who am I on?" Zhang Xiaohu also opened the public channel and shouted.

Because the speed of the landing was not uniform, the people in the shaft were in a mess. In a panic, the safety rope and the control rope behind Zhang Xiaohu were twisted together, and they couldn't be untied at all.

Zhang Xiaohu made a move, quickly pulled out the knife on his waist, cut all the ropes, and then quickly fell down, only a few dozen meters down, he fell on King Peter with a bang. He hurriedly grabbed King Peter in a panic, but under the huge force, he could not resolve the speed of his fall, and soon, he crashed into King Peter and continued to fall downward.

The helmet, which had been sturdy, also began to crack due to the continuous impact. The pungent air outside the helmet immediately came in. He only took two breaths before he felt a little dizzy.

The red lights of various warnings at the watch kept flashing, he had no energy left to care about these, at his current speed, he would fall to the ground below in a few tens of seconds, he didn't know what method Xiji would use to catch himself falling, he believed that Xiji would definitely ensure his safety. But the feeling of this rapid fall is really terrible.

Suddenly, in the vast expanse of blood, he vaguely saw a lot of transparent balloons the size of a basketball floating in the air below.

Then his body crashed into the transparent balloons.

It was an uncanny feeling, as if the balloons didn't exist, unobstructed, effortlessly piercing the layers of balloons that were squeezed together. But what's even more incredible is that the speed of his fall seems to have been stolen by these balloons, and it is getting slower and slower! Getting slower and slower! Finally, after piercing the last layer of balloons, he climbed smoothly on the ground below.

He looked at his body with great curiosity, and except for some hot stinging sensation in his lungs due to the bad air, there was no discomfort in other parts.

"Get out of the way, someone is coming down soon!" While he was still reminiscing, a man grabbed the clothes around his neck and unceremoniously pulled him out of the shaft directly underneath.

Xiji frowned, and Tie Qing looked at his wrist with a blushing face, and just now, two more signals disappeared.

Zhang Xiaohu sat on the ground, took off his helmet, closed his breath, and pointed to the broken helmet, and soon, a female warrior replaced him with a new helmet.

Being able to breathe pure air, the hot feeling in my lungs just now suddenly weakened a lot. He patted the light on his shoulder, and the bright light came on again, and he looked around and saw that it was a huge beach, and under the light, the ground was covered with fine white grains, one by one glowing with colorful glare. As far as the eye can see, it is flat, without any undulations on the terrain.

The head is pitch black, and the top is not visible.

In the depths of the earth's core, there was such a huge space, which really amazed him.

Soon, people in the shaft continued to arrive, and everyone reacted similarly to what he had just done, and the female warriors outside the cave mouth pulled everyone out of the shaft one by one.

Underneath the shaft, there were also several incomplete corpses.

Yan Dacang was not in the crowd, he took the Wu family brothers to take a step forward and check the surrounding situation.

Zhao Zixuan and the others all fell to the ground unharmed, and the last one to arrive was Song Haitao, after him, there was no signal in the entire passage.

Xiji was silent, she had lost nine warriors just now, counting the previous operation, she had already lost a small half of her elite warriors.

The hidden and fearsome adversary behind them is very good at exploiting their weaknesses. They are always able to take them by surprise and inflict serious damage on them.
