After listening to Xilin's words, Shute dialed the communicator and said a few words, and then handed it to Xilin, "You can talk to Boss Huo." ”

Xilin took the communicator and explained to Huo Ding what he knew now, and transmitted a series of data from instrumental analysis to the past, and these evidences were convincing enough.

"Keep all the blood samples and other samples you have collected, I will send someone to collect them, and I will also ask them to collect more samples in the other groups." After listening to Xilin's return, Huo Ding also realized the seriousness of the matter, and told Xilin some things that needed attention.

"Okay, I know, we'll pay attention to ......"

Xilin, who was talking to Huo Ding, suddenly paused, quickly turned around and raised the gun is two consecutive shots, without hesitation and aiming time at all, all the actions were done in one go.

Bang! Bang!

Over there, Schutte was still talking to the team about things, and when Schilln raised his gun, Schult had already realized the danger, but before he could react, Schillin's two bullets came over. The bullet swept through the ends of the hair in Shute's ear, and the burning heat of the bomb just flew on his face, and the burnt smell of the hair remaining in the air being burned by the bullet flying at high speed.

It was a black rat with a tail length of about two meters, and when the first shot hit it, the bullet only exploded in a small area on its body, and the drug did not penetrate quickly into all parts of its body, so if it was not for the second bullet that followed, he still had the strength to break the paw of Shute who was facing away from it.

The black rat that had been hit by the two bullets fell to the ground and twitched, its knife-like claws scratching at the ground with several deep claw marks. It is clear that they are much more resistant to the drug in the bullet than those of the black rats in front of them.

While the blood stains were not completely powdered, Cillin quickly took out the needle and sucked a little of the blood on the ground and put it into a small tube containing neutralizer and anticoagulant. In the eyes of everyone, they dug up a piece of meat from the big black rat and soaked it in a bag containing a neutralizer.

The members of the group only felt chills in their backs, and they didn't know whether they were scared by the black rat or by Xilin. Doesn't this kid know how to do something reassuring?! The black rat was still convulsing and didn't lose his breath, so the kid ran over to get blood and dig up meat, and he was not afraid that the black rat would have another paw before he died.

The black rat's blood-filled eyes gradually dimmed and blackened, and finally he lost his breath, and then slowly powdered. But those few sharp knife-like claws were still intact.

"Thank you." Shute came back to his senses and said. Although he was talking to the team members just now, he was still vigilant, but no one noticed the approach of the big black rat, and he himself only realized the danger when Xilin raised his gun. Although Shute had his back to the black rat, he could also perceive that the speed of the black rat rushing towards it was several times faster than the black rat in front of him, and it was silent, and it was too late for you to notice it.

The communicator with Huo Nail is still on, and from the image setting on the communicator, Huo Nail on the other end has already seen the scene just now, and there is no need to prove it, Huo Nail has really seen the stronger black rat that Xilin said. If there are all such black rats under the base, the consequences are really unimaginable.

If it weren't for Xilin's reminder, it is estimated that when all their personnel were encircling and suppressing the "rat's nest" in the waste treatment plant, the hidden black rat elites would take the opportunity to kill the research institute in the central area of the base and the personnel of the last two brigades who went to the rescue.

Pick up the intact black rat paw and scratch it on the laboratory table next to it, and the hardened plate on the surface can easily be cut open.

"Wow, this thing is so powerful!!" One of the team members was surprised. This was completely beyond their predictions.

"This big black rat is probably here to inspect, and the team to see the operation has left, after all, according to the time, the other groups should have left the base to go to the waste treatment plant, but we are still here." Cillin spoke his guess, and the fact that the black rat was able to come back safely showed that it was not afraid of the rat poison sprayed in the underground passages.

"I've asked six teams to return, leaving two teams and armed aircraft to go over there, and if that side can't cope with it, let the armed aircraft use high-energy artillery to level that area." Huo Ding didn't bother with the waste treatment plant now, and he fidgeted at the thought of Xilin's words.

On the other side, when the protective shield in the central area of the base was about to be opened, the tenth team was urgently stopped by Huo Ding when the rescue work was carried out, and at the same time, the engineers who were repairing the power supply and other important equipment protected by the ninth team were hurriedly brought back to the aircraft, and the base was too dangerous.

The samples and data submitted by Xilin were immediately processed, and then Huo Ding gave each captain a new order, and sent another machine into the underground passage to expand the size of the passage, otherwise the soldiers would not even be able to move after they went down, and only became food.

But it's strange that the deeper the hole goes, the bigger the hole becomes, and there is no need for a machine to expand the hole. When the machine entered a certain depth, it was scratched by the black rat below, but before the machine could be destroyed, the detection device carried on the machine showed a large number of anomalous lifeforms underneath. This confirms Cilling's speculation.

However, another question was raised. Why is the hole down there so big? Does this mean that there are bigger black rats? The jury is still out on this issue.

Perhaps because they realized something, the black rats hiding deep under the base began to move early.

Eight teams, some of which went underground, and some of whom remained throughout the base.

Because Huo Ding has already confessed, each operator fired more than two shots at the black rats that crawled out of the hole, except for the hole that had been opened by the base, this group of big black rats opened a lot of holes in the place that deviated from the fire of the action team when they rushed to the ground.

They are like a bunch of crazy avengers, not taking their own lives seriously at all, just rushing towards the central area. Due to the speed and sensitivity of these big black rats, it undoubtedly reduces the hit rate of the operatives. And the action team has to change places from time to time, because if they stay there, a big black rat may suddenly emerge from below. Several people had already been dragged into the hole by the big black rat that suddenly rushed out, and they didn't even have time to scream.

Cillin's group went underground, and the hole was dark, but they had a darksight device on their mask, after all, there weren't as many jamming devices as there were inside the base. The team members cooperated very well, and there were no casualties for the time being. In the underground cavern, the fire points are more concentrated.

As we go deeper, the hole grows larger and the three personnel can walk side by side. At a fork, everyone saw a pool of blood, not black rats, but human blood, and at the same time, there was a faint cry for help.
