There weren't many messy marks around the bloodstains, which meant that there hadn't been an intense battle, but it also meant that those people hadn't been able to put up much of a fight against the attack.
Shute gestured with his hand. Stay alert, cover, and move to the other side to rescue them.
Silin crouched down against the wall, took out a small box, and scraped a layer of soil off the wall. The squad members saw Silin's actions, but didn't pay attention to him. They only looked around vigilantly. After all, Silin had done this before, so everyone thought that Silin was taking samples.
In truth, what they didn't know was that Silin's real goal wasn't to take samples, but to use this as a cover. He pulled his finger out of the glove at an angle that no one would notice, and touched the wall and the floor to analyze the minute traces. Even the most advanced equipment wasn't as convenient as the chip in Silin's body. The moment he touched it, the feedback from his finger allowed Silin to know what kind of black mice had attacked the operatives here.
It was different! It was different from the big black mice that dug holes he had encountered before! It was stronger!
Silin wasn't sure how strong it was, but he had a feeling that those people had encountered the leader of these black mice, which was the mutated black mouse that had escaped from the base.
When Shute found the member who had called for help, he was already on the verge of death and had fallen into a deep coma. Under the illumination of the flashlight, everyone could clearly see that one of the member's legs had been bitten off, and his body was covered in blood. The medic in charge of the squad came over to help him stop the bleeding, but before he could finish bandaging the wound, he had already passed away.
"I'm going to kill those bastards!" One of the squad members' eyes were bloodshot, and he punched the wall in grief and indignation.
The others had similar expressions.
Shute took a deep breath and said, "They're showing off. They could've gotten rid of everyone without a sound, but they just had to leave one heavily injured."
"He lost too much blood, and the rat poison has already invaded his internal organs." The medic picked up two empty tubes. "We've already injected the antiserum into both tubes, but it didn't have any effect. This rat poison is too strong. "
"Captain, there's no signal on the communicator!" One of the squad members suddenly shouted. Originally, he wanted to contact the reserve team and report the current situation at the same time, but he did not expect that there would be no signal at all.
Every team brought a signal receiver with them when they entered the cave. Every time they reached a certain distance, they would install a receiver on the walls or ceiling of the cave as a disguise. The signal was quite strong just now, but now there was no signal at all. What had happened?!
Silin thought to himself. Their intelligence, no, it should be said that their intelligence far exceeded people's expectations. If every team had done their job properly, and the signal receiver had been installed and concealed, but there was still no signal, then either the receiver had broken down on its own, or the black rat leader had dismantled the receiver. The former was unlikely, but the latter was very likely.
It sounded incredible. Even if Silin said it, not many people would believe it. How could a disguised signal receiver be removed? And to tear them all down so thoroughly? Was this a rat or a human?
Silin had never underestimated the black rat leader from the start. The more information he came into contact with, the more Silin felt that this black rat was very powerful, be it in terms of intelligence or combat ability. Moreover, Silin was gradually finding the frequency of that sound.
Shute thought for a moment, then took out his soundwave detector and pressed it. The reason why he had not used it earlier was because there was a high chance that the black rats would know their location when they used the soundwave detector. But now, Shute couldn't care less. He kept feeling that something was wrong.
Looking at the image displayed on the detector, Shute's expression changed abruptly. "Get out of here quickly!!"
They had only taken a few steps when the walls and ceiling of the cave were drilled through, and the black rats rushed over one by one. These black rats had appeared in a very coincidental position, separating Silin and another squad member from the other eight people in the same squad. Due to the increasing number of black rats, even if Shute wanted to rescue them, there was nothing he could do. The distance between the two parties was pushed further and further by the black rats. Gunshots rang out incessantly, but these large black rats were not as easy to deal with as the small black rats from before. They were very oppressive.
Silin and the other squad member quickly retreated to the other side of the cave, their guns never stopping. But fortunately, the number of black rats that had appeared was not too high. Silin and the other squad member fought for more than ten minutes, and no more black rats came after them. The two of them stayed in another cave. They had lost contact with the other eight people in their squad, and they did not run into any members of the other squads either. Only the sound of their breathing could be heard in the quiet cave.
"Looks like we're safe for now." The man smiled.
"Yeah …" Silin smiled as well.
"Pfft!"
An arrow of blood shot out from the side of the man's neck.
The man's eyes were filled with disbelief. He really did not expect Silin to act so quickly!! How could a normal person be on guard against a teammate in a situation like this?!
When the man said 'we're safe for now', a normal person would let out a temporary sigh of relief and relax their tension, much less when their teammate was right beside them. However, the man's carotid artery was cut by Silin just as he took out his knife. Due to the intense rat extermination exercise just now, his blood flowed quickly, and it did not take long for him to stop breathing due to excessive blood loss.
Silin played with the rat claw in his hand and looked at the man on the ground. He let out a few almost inaudible sounds from his mouth. This was the first time Silin had used it after decoding the black rat leader's voice frequency. Silin had been searching for that voice and decoding it ever since he entered this network of deep underground caves.
Silin did not linger any longer and left the place. In less than a minute, a couple of black rats would come over and eat that squad member. In a situation like this, Cillin would be able to deal with the few threats hidden in the operation team better if he was alone.
Ever since he entered Seven Lights, Silin had never overlooked these hidden dangers. Whether it was a student, a researcher, or a soldier, Silin had never let his guard down. Aiflon's opponents had actually extended their hands into the military. How interesting, as expected of Aiflon's opponents.
Silin's performance was very eye-catching when the group had just come down from the armed spaceplane to kill the black rats, but no one would have thought that Silin was also paying attention to the minute changes in every squad member. From these minute changes, Silin was able to guess the hidden dangers. Silin was able to confirm his suspicions through the series of events that followed. In truth, before the black rats had separated them from the other eight people in the group, Silin had purposely walked a little slower. That person was obviously looking for an opportunity to kill Silin as well. The duo were at the back of the group, and Silin had calculated where the black rats would appear. Silin's speed and the distance between him and the eight people in front of him were all within his calculations. It might seem like a coincidence that the black rats had separated them from the other eight people, but it was all within Silin's calculations.
Silin did not need a sound wave detector to detect the sound waves coming from the cave walls. A normal person would not be able to sense it at all. Silin was like a multifunctional precision instrument that was analyzing the information around him at all times. He knew that the black rats' arrival was not a coincidence, but the result of the black rat leader's command.
Like a human-shaped detector, Silin knew everything that was going on around him like the back of his hand. How many people in the group had just passed through which cave, how many black rats were at which cave entrance nearby, and so on. He knew all of this, which allowed Silin to avoid a lot of trouble.
Looking at the buckle of his backpack, the corner of Silin's mouth curled up slightly. The next one should be appearing soon.
In front of him was a corner of a cave entrance. Silin slowly walked over, and just as he was about to reach the turning point, the rat claw in his hand shot out like lightning.
Pfft!
At the corner, a person wearing a combat suit had his throat pierced and was directly nailed to the cave wall. His eyes were also filled with disbelief, and the gun in his hand fell to the ground. This was originally meant to kill Silin.
The rat claw's trajectory was in an arc! Not to mention that it was so accurate in an environment like this inside a cave! This was something that the person had not expected.
Silin pulled out the rat claw, and just like before, it let out a sound that was difficult for human ears to distinguish.
In the following period of time, Silin took care of three more people.
There was a mini tracking device at the buckle of Silin's backpack. This was installed in the backpack before the equipment was distributed, and it was specially sent to Silin. It was obvious that they had long since prepared to find an opportunity to kill Silin here. However, they did not know that Silin had already detected the tampering on the backpack when he received it.
This was the so-called beat them at their own game.
After walking in the network of caves for so long, Silin could already clearly feel the number of black rats decreasing. Since Silin had provided blood samples and related data in a timely manner, the operatives were able to make adequate preparations, reduce casualties, and improve efficiency.
As Silin walked, he suddenly stopped and turned around.
In the darkness, on the other side of the cave, a large black rat nearly three meters tall stood there, its red eyes emitting a bloody glow in the darkness.
"You've finally appeared. I thought you'd keep hiding from me." There was a hint of a smile in Silin's tone. "That thing inside your body, I want it."
