At this time, a second batch of large dinosaurs appeared in the rear again, accompanied by some amphibious giant beasts, and the emperor crocodile was also among them.

"Damn, it's endless, it's still coming, these small ones haven't been killed, and these big ones are coming again." Looking at the small dinosaurs that continued to appear and the big dinosaurs that reappeared, the hearts of the members of the Cheetah Force were suddenly desolate.

At this time, the laser device was also overheated under the continuous attack and the attack interval was lengthened, and after the continuous fighting of the people for several hours, these heavy weapons were not easy to carry, and under the continuous blow of the recoil, the members of the Cheetah Force were already exhausted and out of breath.

And to be able to tire them like this, the members in the monitoring room can see their fatigue, especially the members of the 3 teams of Jason and others are so tired that they are almost falling to the ground, if it weren't for the strong willpower to carry it, I'm afraid they would have been exhausted.

Being able to tire the members of the Cheetah Force like this shows how terrifying the crazy attacks of this group of dinosaurs are.

"All retreat, close the bases on the ground, and retreat all underground." Following the words of Dr. Varnell, the head of the base laboratory, the captains on the top floor of the Cheetah Force glanced at each other, and quickly led the team members towards the bottom of the base with great reluctance.

When everyone retreated underground, the first floor on the ground of the base was completely sealed, and then the basement floor was closed again, and after three consecutive floors, the base began to enter a state of imbecile maintenance.

Previously, the base of country M also sent a signal to the territory of its own country, so that they could rescue immediately.

And while the base of country M was on guard and waiting for rescue, the angry army of dinosaurs completely destroyed the upper layer of the base of country M, and the wreckage on the ground also left countless dinosaur paw prints.

At this time, outside the Austrian base, some of the mutant dinosaurs also arrived, but this small group of mutant dinosaurs was killed outside the Austrian base that had just repaired the haode defense system. In the absence of a large amount of backup, Austrian researchers easily brought back these killed mutant dinosaurs.

"Doctor, the test results are out, this is a genetic mutation virus, which can change all the genes in the dinosaurs, and prolong their lifespan, but the disadvantage is that the dinosaurs lose their minds, and this virus can affect any living thing." Although Austria's scientific research jishu is not strong, it is comparable to that of Konichi.

Under the testing of such a product, the ingredients were quickly analyzed. All of them were cultured from new viruses that arrived on dinosaurs in advance, plus known terrible viruses.

Some of these abilities are physical fitness, but because they are not perfected, this physical fitness has become an alternative destructive mutation.

And the cultivation of this virus, Austrian researchers don't have to think about it to know that it must have been made by this crazy little Japanese country, and only their perverted thinking can make these things.

Austrian researchers immediately thought of the terrible spread of this highly transmissible virus on this dinosaur island, once so many dinosaurs on dinosaur island were all infected, unless they left here, no one would be able to escape the attack of this group of crazy dinosaurs.

"Quickly put together all the important information, and put everything that can be put together. We quickly left Dinosaur Island, evacuated all bases, and told the Thorns Force members to come back quickly and leave here. Thinking of the key Austrian base, the person in charge immediately gave the order to evacuate all.

As soon as this order was issued, the entire Austrian base immediately entered the highest level of tension. Everyone packed up everything, and the support members who had just arrived but hadn't yet heated their butts quickly packed up.

When the Austrian base retreated quickly without everyone knowing, the members of the Thorn Force outside the Huaxia base were stunned.

The explosives on everyone's bodies had just been installed on the defensive roof of the Huaxia base, and they had not yet had time to detonate. The base issued an order for an emergency retreat.

The members of the Thorn Force who originally expected to be able to break into the Huaxia base all felt aggrieved, but after knowing the madness of this group of mutant dinosaurs, the leader of the Thorn Force was also greatly surprised. Something like this broke out all of a sudden, if I went back late, would I be wiped out by this group of dinosaur frenzy.

Think about the many dinosaurs on this dinosaur island, when they are all gathered together, think about it, you know how terrible they are.

"Go, everyone retreat, blow up their roofs. Don't look at it, it's a pity for this fireworks display. With the order of the leader of the Thorn Troops, everyone began to retreat, and after everyone reached the farthest distance of the remote control device, the leader pressed the switch and kept retreating.

Although the sound of explosions was heard from behind, he had no time to pay attention to it.

"The roof of the base is 70% damaged, but fortunately, the defense materials researched by the doctor can transmit the energy reaction of the explosion, otherwise I am afraid it would have been blown up." With the end of the explosion, I thought that the members of the Thorn Force were going to continue the attack, but I found that the members of the Thorn Force were no longer outside the base.

"Where did the other party go?" Under a hidden surveillance device, no members of the Thorn Force were seen, while the surveillance equipment at other distant points was damaged and could not be observed.

"The other party has retreated? Impossible? Could it be that our people are back? Pilot-Huang said to himself.

"It shouldn't be our people who are back, but I'm afraid it's not far away, and the other party may have gone to ambush our members of the Blade Force." Captain Li saw traces of the other party's departure on the existing monitoring equipment, but it was impossible for the other party to leave at this time.

Only when your own Blade members return will they be able to give up attacking their base, and if your own Blade Force members return, they may run headlong in the same way they left.

And the other party can't still bump into it in such a situation, the only possibility is that the other party wants to ambush the members of the Blade Force.

"If you want to ambush our members of the Blade Force, damn it, Pilot-Huang, let's open the base, otherwise the people who have ambushed us will be in trouble when they come back to deal with us." Captain Li said to Captain Huang.

"It shouldn't be so soon, our people are arriving at the base of Xiaori Country and adding damage, even if there are not many casualties, it is impossible to come back so quickly." Pilot Huang speculated. (To be continued......)
