The steel wire fence at the underground connection between the laboratory and Beihai City has not been destroyed, proving that the mutant rats have not been here.

After a few people entered the underground of the research room, Chu successfully controlled the wire and sealed the intersection, and by the way, it was also reinforced.

After entering the research room, it is much easier to do it, and the research room belongs to a group of people who know in advance the coming of the end times, and even their research is related to this.

Therefore, the study is equipped with the most complete security system, and air circulation system.

It's just that the end of the world came too suddenly, and they didn't have time to leave the city, so they could only close the door of the research room and hide in the safe room built at the beginning of the establishment of the research institute.

There is plenty of water and food in the safe house, as well as all the amenities you need. The walls of the surrounding rooms are made of concrete mixed alloy and are two meters thick.

The gate is pure alloy with a corrosion-resistant structure.

When the institute was closed, the peripheral systems were soon turned on as well.

But for some reason, a group of zombies has been surrounding here, and there is even a terrifying tyrant stationed there.

Researchers in the lab can only be trapped here, waiting for rescue.

At this time, the research room is in the safe room.

The safe room is about 300 square meters in size, and it has all the facilities inside, and there are even several operating stations.

"Professor Yang, look."

The security room was equipped with a surveillance system that could monitor the outside world with cameras all over the research room, and the military even installed cameras in the underground drainage system for the safety of the research institute.

At this time, most of the cameras were corroded due to the corrosion of blood mist, but some of them were barely working.

Just now, a female researcher pointed to several black-armored figures on the monitor and exclaimed.

Professor Yang is an old man with gray hair, a kind face, and a small stature, but he has a temperament of his own.

At this time, I heard the scream, and hurriedly ran to the monitor to watch.

"The military has finally come to our rescue."

Many voices of joy echoed in the small safe room.

For a few days, the safe house was heavily fortified, and about two months of food was kept inside. But that feeling of isolation is really torturous.

Since the outbreak of the apocalypse, it has been almost a month, and it was okay at first, all kinds of communicators, such as mobile phones and computers, although they were disturbed and could not be used, but at least there was still electricity, but with the outbreak of blood mist, the lines in the blood mist were all corroded.

Even if the institute was equipped with a generator, on the 15th day of the end of the world, the equipment finally became overwhelmed and stopped functioning, and the safe house was now available except for a few well-sealed monitors.

At first, they waited hopefully for the military's rescue, but as the days passed. Except for the increasing number of zombies on camera, there is not a single shadow of a living person. Their spirits were in despair.

How can you not be excited when you see a living person at this time.

"Lao Li, you can also come and see, you are from the military, see if these people are soldiers."

The person known as Professor Yang shouted.

"It's coming, it's coming."

A neutral voice rang out from the crowd. Lao Li is a professor of biology at Huaxia University, but he did come from a military background, and he fought dozens of tragic battles with the army when he was young.

At this time, Lao Li walked to the camera and looked at it for a while

"Yes."

There was another cheer below.

The few people in the camera are Qin Ming and them, at this time they are all pure black armor, there is no army symbol, it is difficult to distinguish, but the military tactical actions and words between the few people still show their identities.

Chu Chenggong had a map of the research institute, but at this time, several people were facing a problem.

They were blocked, and as they climbed up the sewage pipe and were about to reach it, an almost solid alloy manhole cover covered the mouth of the passage, with a ten-centimeter-thick alloy plate.

Chu Chenggong put his hand on the alloy manhole cover. on, after a moment, muffled voice:

"It only contains a trace amount of iron, and there are other unknown substances interfering with me, I can't control it, Chen Ping, you can try it."

Chen Ping was the most powerful of the several people, Qin Ming had used the system to detect him, and his physical strength was 65.

It seems that Chu Chenggong intends to let Chen Ping use brute force to directly push away this alloy plate.

Chen Ping climbed to the top, raised his hands and propped up on the alloy manhole cover, his body swelled, and he exerted his strength violently.

"Click"

A cracking sound came, and Chen Ping fell directly without standing firmly, but fortunately grabbed the ladder next to him when he was about to land.

A few people huddled in place is a circular passage where a person is vertically upward.

There are ladders on both sides that can be climbed, and these ladders are made of iron, and because they are made of iron, they have long been rusted. It was still reinforced with Chu Chenggong's ability, and a few people climbed up.

At this time, several people were seven or eight meters above the ground, and there was no place to put their feet, so naturally there was no force point.

Chen Ping exerted his strength violently, and did not push open the alloy manhole cover above his head, but directly stepped on the ladder under his feet.

After a while, Chen Ping climbed up from below again.

It seems that this will not work, Chen Feng also tried to shoot with a sniper rifle once, but it was useless except for a shallow crater.

Qin Ming's spear can be inserted after it contains blazing energy, but the market in Qin Ming's hand is a spear, not a hammer, how many spears does Qin Ming have to insert to penetrate this layer of alloy manhole cover.

When several people were helpless.

"Sir, I think I can."

Qin Ming's ears heard the voice of a liquid robot.

Qin Ming glanced at him in surprise and nodded and motioned for him to try.

The liquid robot crawls under the alloy manhole cover.

Stretching out a hand, the silver liquid on the arm slowly flowed, and then shaped, and in a short time, a cutting machine about half a meter long was shaped.

The liquid robot aims the cutting machine at the alloy manhole cover, which in the eyes of the liquid robot is only a rough combination of several materials, which is too different from the engineering material technology of other worlds.

He can see the points where the material is not evenly combined, and these points are relatively fragile in place.

Moreover, the structure of the liquid robot is a special set of materials, and the liquid metal can be changed at will according to the needs, which can be hard or soft, long or short, thick or thin.

At this time, the liquid robot was aligned with the point, and violent yellow sparks spread out in all directions, passing through the underground passage, and several loud and even echoed.

Qin Ming's face changed, those giant rats were extremely sensitive to sounds, and they didn't know what creatures were hidden in such a huge underground passage.

Sure enough, the sound of barbed wire sliding was heard in the passage, and it was the barbed wire at the junction.

"Hurry up, there's something coming."

Qin Ming looked at the darkness below and urged the liquid robot.

When the liquid robot heard the urging, the liquid metal from the rest of its body flowed to its left arm again, and its speed instantly increased.

"Hiss"

A strange voice came from the darkness.

It wasn't a mouse, Qin Ming instantly took out the spear and held it in his hand, his eyes staring at the darkness below.

Chu Chenggong and the others also quickly entered a state of combat readiness, and Chen Feng also looked down with thermal imaging, but found that there was nothing.

At that moment, another loud voice came

"Hiss"

A loud sound echoed through the passage, and then two cyan vertical pupils as large as lanterns appeared in the darkness below

Qin Ming suddenly thought of something when he saw these eyes, coupled with that terrifying voice.

"MD, don't be a forest python."

Until the giant beast below turned over, revealing the cyan scale armor, Qin Ming was a little desperate, this is a proper forest python.

In his previous life, he had witnessed the horror of forest pythons.

It was a time when he went out to practice, he was not strong enough at that time, behind a ruin, he saw a terrifying scene, hundreds of meters of pythons were spitting letters horizontally, and there were several huge bones around the slender snake body, each bone was several meters long, Qin Ming even saw the skull of a titan orangutan, at that time, he was so frightened that he turned his head and fled directly, and fled back to the base city to feel a little at ease.

At this time, looking at the huge lantern-like eyes below, Qin Ming held down Chen Feng, who was just about to shoot.

He knew that Chen Feng wanted to blind the eyes of the monster underneath.

But what he didn't know was that even if the Titan Python in front of him was still in its infancy in terms of size, its eyes could not be pierced by a sniper rifle, and the thick eye mask on the back of the python's eyes could only be injured by replacing it with a scarlet bullet.

"Pemba"

The python below rolled over and made a roaring sound, and the cyan scale armor and the surrounding concrete made a harsh grinding sound.

A pair of vertical pupils stared at the few people above, and there was a bit of banter in their eyes.
