Qi Lin swung his bone blade again, cutting three or four bloodthirsty rats that pounced on him in half, and then moved his feet, and began to kill the hordes of bloodthirsty rats while starting to advance towards the place where the squeaky sound came from in the darkness.

When he noticed Qi Lin's direction of movement, there was a hint of fear in the squeak - yes, it was fear, although I didn't know how I heard it, but the subtle change in the tone sent a clear signal to Qi Lin: the rat king who commanded the rat swarm was afraid.

The swarm of rats, which had already followed one after another, became even more frantic under the stimulation of the squeak and the smell of blood, and their crimson eyes turned into countless flying red streamers in the darkness, which made the pressure Qi Lin feel suddenly increase a lot.

However, thanks to the support of [Radiation Battery] and [Rapid Recovery], his physical fitness is not a problem - if he changes to a third-level evolutionary who does not have a wide range of attack methods, I am afraid that he will be consumed alive by so many bloodthirsty rats.

At this time, Cooper's voice sounded in Qi Lin's ears again: "Master, the audio analysis of the Rat King has been completed, and according to the computer's analysis, the Rat King is not a single individual. ”

"Not alone? Are there a lot of rat kings? Qi Lin asked with some curiosity while waving his bone blade.

The Bloodthirsty Rat is only one of the lowest-level mammalian mutant creatures in the wasteland, so even the boss-level Rat King is about one F-level at most, and the F-level mutant creatures, even if there are a few more, it is not a big trouble for Qi Lin, but the coexistence of multiple Rat Kings makes him a little surprised.

Bloodthirsty rats are very common in the wasteland, but it is rare for them to have more than a thousand of them like this - no, judging by the steady stream of bloodthirsty rats from the sewers, I am afraid that this rat colony is already more than 10,000 in size.

The boss of the rat king will not evolve at all in the general small-scale rat group, and the leader is at best the male bloodthirsty rat with the stronger physique and the strongest reproductive ability in the rat group, so although the bloodthirsty rat is very common, players rarely get information about the rat king.

However, according to the habits of social animals, there is no such thing as more than one "leader", because only by becoming the leader of the population can one have the highest priority of mating and the right to control food, and this power is naturally not shared.

For thousands of years, the only thing that broke this rule was one living thing - human beings.

But even so, in the hearts of many people, there is still a dictatorial ambition lurking, which is just an instinctive desire of living beings, and it is precisely because of the existence of this desire that more excellent genes can stand out and be inherited.

"How do I think it sounds ridiculous to have a few rat kings leading the rat herd, did they also form a council, or a cabinet?"

"No, according to the results of the analysis, not a few, at least the voices of eleven individuals commanding the rat swarm, conservatively estimated, the number of rat kings should be about thirteen to sixteen, or more."

“…… So much? Qi Lin was stunned, "Then is this a rat kingdom?" It is just not known whether they are republics or constitutional monarchies. ”

"If you want to know, you can capture the Rat King alive and send it to Base 404, which has a top biological laboratory before the war, maybe it can give you a satisfactory answer." Cooper said lightly.

“…… Forget it, I'm kidding. ”

Cooper returned to a state of silence, and Qi Lin didn't think much about it anymore, his head was stuffed, and while killing those bloodthirsty rats that had gone completely mad, he approached the place where the rat king was.

Although the IQ of ordinary bloodthirsty rats is a little higher than that of the Assasin Servant Spider, their brain capacity is too small, although they also know fear and fear, but under the stimulation of a large number of similar blood, and the "squeak" of the rat king as if he has magical power, these bloodthirsty rats have completely fallen into a state of madness, driven by instinct, the tide is like a Qi Lin.

After more than ten minutes of killing, Qi Lin didn't know how many bloodthirsty rats died under his bone blade, it could be five thousand, it could be six thousand, or more, in short, the road advanced during this time could be described as a "blood road".

Yes, this is a literal blood path, every inch of the ground is covered with the shredded corpses of bloodthirsty rats, and even Qi Lin's cloak and jacket are stained with a thick layer of blood.

In addition to the smell of blood, there was also a strong stench, the organs in the bodies of those bloodthirsty rats, the food that had been digested, the feces in the intestines and the minced flesh of the blood plasma were mixed together, if there really was purgatory, Qi Lin felt that this was probably the scene.

It was already very close to the location of the Rat King, and what made Qi Lin wonder was that although the Rat King's command was full of fear, Qi Lin's position seemed to have never changed as Qi Lin continued to kill and move towards it—well, it was them approaching.

Why...... What if you don't run?

However, when Qi Lin saw the "Rat King" with his own eyes, his doubts were solved.

The so-called "Rat King", in the middle of a large group of rats that rotated like a whirlpool in a torrent, there were sixteen fat rats with large dogs, but to Qi Lin's surprise, the long tails of these sixteen "Rat Kings" were all entangled, and it was not simply entangled, if you looked closely, their tails seemed to have grown together completely, completely indistinguishable from each other.

"What the hell is this......"

Qi Lin waved the bone blade with one hand in his right hand, took the opportunity to raise his left wrist, and aimed his brain at the "Rat King" in the distance.

"[Rat King], F-class mutant creature, boss, leader of the large-scale bloodthirsty rat, for unknown reasons, multiple leader-level bloodthirsty rats constitute a wonderful symbiote, this phenomenon is also occasionally found in the old times of nature, and is mostly considered a bad omen, or the source of the plague.

The rat king has no means of attack and weak defense, so he can only rely on the rat pack for feeding and protection, but he can emit a special pheromone that makes the entire rat pack fall into an extremely manic state. ”

After reading the introduction, Qi Lin felt that in addition to not having the ability to lay eggs, the attributes of this rat king were extremely close to the Assasin spider mother, but compared to the rough-skinned spider mother, the rat king's defensive ability and strength were obviously far behind.

"It's much easier to do if you don't have a lot of defense!"

Qi Lin directly slashed the bone blade horizontally, picked up more than a dozen bloodthirsty rats that pounced, and then went straight to the sixteen "rat kings"-
