Two dirty droplets of water flowed down the tunnel and hit Zhang Xiaohu's cheek lying on the ground. He woke up and turned around, looking at the dark tunnels around him, the oxygen cylinder on his waist was shining with a demonic red light, which was even more eye-catching in such an environment.

He struggled to move his body, and immediately felt a piercing pain in his back. With a light touch of his hand, a hard, cone-shaped stone chip was embedded in his back.

The oxygen mask is no longer effective, so you can simply take it off. The air around me has a strong musty smell, and I don't know if breathing for a long time will cause harm to my body. However, according to his current situation, it is difficult to say whether he can pass this hurdle or not.

The light on his shoulder had been shattered in the fall. He couldn't see his surroundings clearly. However, Zhang Xiaohu had an idea, and thought that the oxygen cylinder on his waist could also send a red light to show the alarm, and in such a place, it could also be used as a backup light source. He endured the pain in his back, gritted his teeth, took off the small oxygen cylinder, and held it in his hand to shine it left and right.

His backpack was scattered not far away, only two or three meters away. He clearly remembered that there was a pain-relieving potion and a spare oxygen cylinder. And there are new light sources in it, which are all things he needs now.

But he had to move around there.

He moved his body slowly, and immediately let out a wail, the injury on his back was too severe, and the wound between the movements of his body made him feel painful.

But he knew he couldn't just lie here. You must take advantage of the fact that you have not lost too much blood and are still fully conscious, and get your backpack as soon as possible, otherwise you will only die while waiting for yourself.

He tried to move again, but it was still painful, his cheeks twitching violently from the pain, but he managed to move inch by inch towards his backpack.

There was still a meter away, his body had reached its limit, his body began to numb, he felt that his body temperature was gradually decreasing, and the scene in front of him became blurred, this was a sign of excessive blood loss, and he had to get his backpack immediately.

He gulped his breathing, gathered some strength, and came up with a good idea. He removed the emergency rope from his waist, tied it to the handle of the dagger, and threw it several times in the direction of the knapsack.

Every time he didn't get stuck in the strap of his backpack, his arm became weaker and weaker, and he decided to try one last time before his body collapsed completely.

His eyes kept on the strap on the backpack, and then, without the slightest hesitation, quickly threw out the short knife in his hand.

"Great!" Not only did he secretly exclaim.

The short knife was stuck in the strap of his backpack, and he pulled the rope on his hand and slowly moved the backpack towards him......

He wrapped his backpack around his chest and first took out a light source from it to illuminate the tunnel, from which he had fallen from a large diagonal hole in the top of his head.

This pit is very large, full of sharp and sharp conical stalactites, so it seems that his luck is not bad, when he just fell, he only a few meters away, the whole person will be pierced by the nearby tall stone pillars, so it is a happy death.

Zhang Xiaohu put the light on his side, then took out the pain-relieving potion and took it, and took anti-inflammatory, anti-virus, and traumatic tablets, the effect of these drugs was obvious, and soon, the pain in his back was greatly reduced.

He took out the oxygen cylinder again, put on the oxygen mask again, and after doing all this, he could finally rest for a while. In order to prevent himself from passing out, he opened his emergency drink, and a sour taste filled his mouth, and the person was immediately refreshed.

Now it's time to think about how to call for help. From the speed and time of his fall, he could infer that he had fallen dozens of meters underground, and he didn't know whether the tunnel was formed by man or naturally, and whether there were other passages above. Can your partner find him in time?

It all started with an accident an hour ago.

After crossing the river, Zhang Xiaohu and the others got into the low bushes and continued to move towards the southeast.

A day later, they walked near a canyon.

On the rock face of the canyon, two huge helipads were trimmed, on which several aircraft were parked.

There are also seven or eight biochemical elite soldiers stationed on the platform.

Through their observations during this time, they concluded how the hierarchy of the bornified soldiers was divided.

The lowest-level cyborg looks like an ordinary person, except that they can stimulate physical changes through hormones in their minds and become muscular warriors, but this kind of cyborg warrior has a low IQ and can only carry out some simple communication. But they can drive some machines and use some low-level weapons. These cyborgs can wear any equipment, and under normal circumstances, they are wearing leather suits and specialized armor, and they are also the most numerous.

Then there are the higher-level biochemical warriors, whose facial features are often very ugly and hideous, sacrificing all their intelligence, not knowing how to think, communicating with each other, and only by roaring. There is no normal feeling, but the combat power is very amazing, the body cells will quickly divide and mutate, and they can become tall and fierce monsters, Zhang Xiaohu and they have suffered the losses of these biochemical warriors. These cyborg warriors are basically wearing only some rudimentary shorts, and their upper bodies are all naked.

Then there are the top level of biochemical elite fighters, who combine all the strengths and characteristics of the first two and also improve their IQ, acting as the mainstay of the No. 4 troops. They were quite well-equipped and wore black armor.

Now on the platform are the most advanced biochemical elite warriors, and their presence here means that this is a very important military facility.

These aprons were built here, and once again blocked the route of Zhang Xiaohu and their advance, but fortunately, the peaks on both sides seemed to be able to bypass.

After some consideration, Zhang Xiaohu and the others decided to detour through the woods on the right.

Although they also encountered some dangers along the way, the five of them, relying on their advanced equipment, were about to successfully bypass these peaks.

Suddenly, a large number of "soul attraction insects" appeared in front of the woods, Zhang Xiaohu himself had learned the power of this inconspicuous small insect, they could not continue to move in this direction, so they had to turn around again and try to detour from the left side of the mountain range.

The terrain on the left side of the mountain range was much more complex, with ravines on the ground, a mix of soft sand and muddy ground, making it difficult to move forward, and they had to watch out for flying machines in the sky and the ground beneath their feet along the way. They saw that in many places, there were many mud pits and quicksand pits of unknown depths. If you make the wrong move, you may fall into the trap of death.

Although the road on the left was a little more dangerous, but finally there were no more "soul worms", they looked at the plain not far away, and before they could breathe a sigh of relief, Zhang Xiaohu noticed that in the air not far away, there were two flying machines about to fly over their heads. They had to hide right away while being spotted by the aircraft.

Not far in front of them, there was a huge bluestone, more than ten meters high, and the shape was strange, they hid underneath, they would definitely not be discovered by the flying machine, so the five people quickly squatted under the bluestone, watching the two flying machines quickly pass overhead.

"Boy! Thankfully, we have time to hide underneath here, otherwise it would have been dangerous! King Peter rejoiced.

Looking at the tired companions around him, Zhang Xiaohu said: "Everyone hold on a little longer, we will soon go around, when the time comes, let's find a safe place to rest, and then go on the road!" ”

"Captain, you don't have to worry about us. You're tired too, so you have to be careful! Peng Jiadong said with concern.

Zhang Xiaohu smiled faintly and said, "Don't worry, my life is big!" After saying that, he was about to take the lead and continue to walk forward, but the ground that collapsed with his left foot was extremely soft, and before he could react, the ground under his feet suddenly collapsed, and he suddenly lost control, and slid all the way down the pit below, and fell here.

......Suddenly, in the silent tunnel, there was a slight sound of footsteps, as if some animal was hiding in the darkness around him, Zhang Xiaohu hurriedly turned the light source to the maximum, and the surroundings were immediately bright, and a black animal roared and quickly dodged into the darkness.

At this glance, Zhang Xiaohu saw a thick hind leg and a fluffy tail, it was indeed a beast, but he didn't see the monster's appearance clearly.

This monster is hiding in the dark, it must be premeditating something unfavorable to itself, and it is definitely not here to accompany itself. Zhang Xiaohu thought. He retrieved a self-igniting lamp from his backpack and brightened it all around him while praying that his companion would be able to get there soon to save him.

He nervously observed his surroundings, and even the injury in his back didn't seem to hurt so much, and he held his short knife in his hand. His long and short spear was already in the process of falling, and he didn't know where he had thrown it, and now he could only rely on the dagger in the wind to defend himself, hoping that the monster would be afraid of his own fire, and not rashly attack himself, otherwise, he would really be more than lucky.

"Roar! Roar! The roar of monsters suddenly sounded around them, and there seemed to be quite a lot of them!

"Click!" "Click!" The footsteps around have become more dense!

No wonder the monster just now didn't attack, it turned out that it was waiting for its companion.

Suddenly, a black shadow quickly rushed out of the darkness towards Zhang Xiaohu, and a bloody mouth was ready to bite Zhang Xiaohu's right leg......
