At the moment when Zheng Wei shouted, the three of them immediately felt that the ground under their feet suddenly shook, and the movement from the ground was several times stronger than in the previous days, and Liao Yu could even feel that the source of the shock was frantically approaching the ground.

"What's going on, no matter, save people."

Liao Yu hurriedly shouted, his original plan was to find a good time, after most of the people had left the cave, Zheng Wei would control the skeleton warriors to find the weak point and detonate the bomb, so as to minimize the casualties.

However, the only thing Liao Yu didn't expect was that he underestimated the action of these people, and in the suffocating oppressive environment year after year, people's psychological endurance will continue to increase, and the psychological pressure will also reach a great critical value.

When a person discovers a path that may have hope, he will subconsciously pour all the pressure on his body on this thorny road, intending to tear down the fence in front of him in the shortest possible time and see the dawn of hope.

And for the people below, the six hours since Liao Yu and the three of them got back the three-headed hatchlings have been too long.

Qing Jue looked at Liao Yu and the two who rushed down, pulled the corners of his mouth, and did not move his body.

And Liao Yu didn't care about Qingjie, at this time it was the final moment of the poor dagger, as long as Qingjie didn't suddenly distort her mind and wanted to take revenge on herself, then it didn't matter what she did.

With the blessing of swift power, the two quickly rushed to the entrance of the cave, and began to help pull and support the humans rushing out of it one by one, and plumes of smoke began to pour out, and countless people coughed and rushed out of it.

At the same time, the alarm sounded earlier had already alarmed the residential area on the other side, the heavy gate was opened, a group of uniformly dressed men with guns were running towards the place, and a group of medical personnel were carrying stretchers to follow.

"Why did you get back?"

During the rescue, Chu Fei caught a glimpse of Liao Yu and Zheng Wei, rushed over and grabbed Liao Yu's arm and asked.

"Nonsense, such a big movement, do you think those monsters are not alarmed, we have to get out."

Liao Yu replied with a spare rhetoric that he had thought of a long time ago, the three of them had never shown up in the series of operations just now, and those lightning bolts were completely beyond the cognition of this group of people in this era, so Liao Yu was not worried about revealing the problem at all.

"Damn, how could this be."

Feeling the vibrations under his feet that were becoming more and more frequent and amplitude, Chu Fei's face changed again and again, and finally he seemed to have made up his mind, and he desperately grabbed Liao Yu and shouted in a low voice: "For the sake of the same Huaxia people, can I ask you something!" ”

The roar around became more and more deafening, and Liao Yu had a lot of guesses about the request that Chu Fei was about to say, so he could only suppress his apologies in his heart, and also roared back: "No problem!" You say. ”

"This cave is connected to the underground, and that's always been a secret to us. Ever since the first people found a huge skeleton left over from the struggle of a bunch of monsters and other creatures near the research institute, they found it all the way to this place and began to study, only to find that it seemed to have been sealed with rocks by some creature. ”

Liao Yu didn't interrupt Chu Fei's words, because he knew that this might really represent the last hope of their group, and he was the only one who listened.

"The institute existed for several years before me. During this time, an underground monster managed to break out of the seal, but in terms of size, it was much smaller than the skeleton we found. But it was only a few times that we found that these monsters were very hostile to these creatures on the ground, and eventually they all left us to fight these monsters. ”

Listening to Chu Fei's narration, Liao Yu seemed to be able to see countless people trembling and staying here with that little hope over the years, hoping to find a way to go home and lead to their former lives from those dead and silent skeletons.

"So you're thinking if you can do some experiments and use the genes of underground monsters to create something that can deal with the kind of monster that can deal with the kind of monster that Queen Spider ...... soldiers, so that you have a chance to escape, or you don't have to be in such a precarious situation. ”

When Chu Fei was gasping for breath, Liao Yu opened his mouth to complete his unfinished words, and Zheng Wei didn't know when he had already stood behind Chu Fei, if Chu Fei wanted to take any tough action, the two would not have no capital to negotiate.

"So, I hope that if you can go out, you will have a chance to come back and see us again."

After that, Chu Fei approached Liao Yu's ear and quickly said the latitude and longitude of the location.

Liao Yu understood what Chu Fei meant by coming back to see, looking at Chu Fei's bloodshot eyes, Liao Yu couldn't say the words of refusal, but the struggling hope behind these eyes made Liao Yu, who thought that he had no psychological burden on this kind of lie, suddenly couldn't open his mouth.

In the end, Liao Yu didn't say a word, just nodded heavily. Before the three of them could move separately, there was a sudden sound of wings flapping overhead. With the help of the faint light of the camp, Liao Yu could vaguely see countless dense black shadows rushing into the sky in the distance.

"Hidden! Turn off the lights in your hands, everybody! ”

Chu Fei, as one of the commanders, immediately began to yell around, and at the same time, the lights in the residential area began to disappear rapidly, leaving only a few spotlights into the air.

At this time, Liao Yu and Zheng Wei had no way to continue to save people, and the current situation was becoming more and more chaotic, and the two could only seek self-protection first. Under the light of several huge spotlights in the residential area, Liao Yu was able to see the group of monsters that attacked first, and it was the huge pterosaur they had seen during the day.

At this moment, no less than thirty giant pterosaurs were swooping down with a sharp chirp, and with their huge size of more than ten meters, the huge night sky seemed a little crowded.

In the face of such a group of dinosaurs, Liao Yu and Zheng Wei's strength could not play any role at all. They could only fall into the grass for the time being, trying to hide their figures.

The machine gunners of the research institute had been patiently controlling the timing of the shot, and it was not until the moment when Liao Yu, who was half-crouching in the grass, could see the texture of the skin on the pterodactyl's body, that several tongues of fire suddenly erupted from the fire point in the residential area.

The three-headed pterosaur that rushed to the front was beaten into a sieve by the machine gun that gathered fire in just two or three seconds, and the blood rain poured down in mid-air, causing many women below to scream, but these screams were quickly held deep in their throats, so as not to attract the attention of these huge pterosaurs.

Liao Yu estimated the distance between himself and the pterosaur, and it was at least more than 100 meters from here to the research institute, plus the pterosaur took a circling and reciprocating attack method, and all his attack methods could not be intervened, and he was a little helpless for a while.

While using concentrated fire, the institute used turns on and off the illuminating lights to interfere with the pterosaur's line of sight. If it is put on the battle with humans, this method is too inefficient, but when it is replaced by dinosaurs whose IQ and coordination ability are obviously inferior to humans, the effect is remarkable, and the pterodactyl that was directly shot by the strong light obviously gave up the intention of attacking, and the claws were randomly propped up on the outer wall of the research institute, and after tearing a few holes, they flapped their wings and circled before attacking again.

It can be seen that the institute has survived here for so many years, and has gradually developed a set of effective tactics against all kinds of dinosaurs, and the corpse of more than half a pterosaur has been smashed in front of the gate of the institute.

Liao Yu hid on the sidelines and secretly observed and learned the combat methods of these real soldiers, and no one knew whether he would be thrown into the battlefield by Hantang in the future. However, Liao Yu also noticed that even though the casualties of the pterosaur were very different from those of the research institute, as the fire points were dug up alive by the pterodactyl with flesh and blood against the rain of bullets, the density of the gunfire decreased significantly.

Seeing this scene, Liao Yu couldn't help but think of the look in Chu Fei's eyes before he left just now, and he couldn't help but feel gloomy in his heart.

It's no wonder that these people are basing their hopes on such a difficult project as genetic modification in an attempt to cause chaos in order to survive. After all, the human beings here are rootless trees, ammunition supplies, medical drugs are used a little less, how can the resources obtained from the jungle be comparable to the consumption of this kind of battle.

Liao Yu can even be sure that with the size of the base, no matter how overestimated it is, it will not be able to survive ten beast tides, which is already completely ignoring the wear and tear of weapons and ammunition failure.

It's just that for them, five, ten, twenty times, what's the difference, as the saying goes, the most feared time of the death penalty is not at the moment of losing life, but when waiting for death to approach you step by step.

At this time, Zheng Wei glanced at Liao Yu and whispered, "The task has not changed yet." ”

However, there was no blame or suspicion in his eyes, as if he simply reminded Liao Yu like a time.

"Wait, and there are dinosaurs on the way."

Liao Yu said as he glanced in the direction of the depths of the jungle, judging from the tremors on the ground, no less than the vibrations underground, which were constantly coming from there.

At this moment, there was finally a violent shaking of the earth in the depths of the cave, accompanied by several piercing loud hisses, and the ground of the entire cave clicked like a cracker tearing out a huge crack of more than two meters, and many experimenters fell into it without being caught off guard.

At the moment when the crack appeared, Liao Yu quickly grabbed Zheng Wei, whose figure fell suddenly, and threw it out with a force from his waist. The two rolled on the ground several times before stopping.

At this time, Yan Yin, who had always made Liao Yu and Zheng Wei nervous, finally came with new mission news.
