"Squeak squeak-" After a sharp mouse cry, the rat swarm was silent, and the next moment, the rats rushed up as if crazy, trying to block the crowd's path.

How sensitive the burnt white ears were, and how special the mouse's cry was, how could he not hear it. Jiao Bai turned his head and looked in the direction of the voice just now. A golden-haired rat's tail flashed away and hid in the mouse.

"I said how did such a large swarm of rats come about, it turned out that you, the golden retriever rat king, were you gathering the little brother to come over for revenge, it may disappoint you, but these first- and second-level little guys, no matter how many they are, they are just here to deliver food."

Talking to himself, Jiao Bai then ordered the summoning beast to open fire, and in a moment, the ground thorn of the Rui Beast, the ice and fire breath of the Hell Two-Headed Dog, the black water attack of the Black Water Snake, and other skills, completely covered the rat swarm blocking the way of the survivors. Under the attack of the powerful skills of the fourth-level summoned beasts, the mutant rats of the first and second levels were as fragile as inflatable toys, which could be broken when they poked. After the skill, the mutant rat colony died one by one, and the way forward was opened up, and people were able to move on.

And Jiao Bai himself took out a strange-looking weapon from his personal space, this weapon has a metal pipe more than two meters long, and a bucket-sized steel cylinder is connected to a soft leather tube at the back.

Jiao Bai carried this weapon, came to the rear of the survivor team, unscrewed the valve on the cylinder, pointed the metal pipe in the direction of the rat swarm, and decisively pulled the trigger for firing. In the midst of a "snort" sound, accompanied by the sound of crackling electric sparks, the next moment, a huge fire dragon erupted from the metal pipe and pounced on the rats. Countless mutant rats were burned by the fire dragon, and the hair on their bodies burned instantly, followed by the skin and subcutaneous fat, and in just a short moment, all the mutant rats affected by the fire dragon turned into charred corpses.

It turned out that what Jiao Bai had in his hand was a portable flamethrower, which was originally designed to deal with the enemy's swarm charge on the human battlefield. Now it's changed to deal with the mutant rat swarm, and the lethality is just as unambiguous, and the large swaths of rats are killed in the sea of fire created by the flamethrower, turning into charred corpses. With the sharpness of the flamethrower, Jiao Bai alone actually blocked the pursuing rat swarm in the subway station, and the scorched rat corpses piled up in front of him were stacked in a thick layer, and I don't know how many rats died under his attack.

With the opening of the summoned beast and the scorching white, the survivors successfully entered the passage to the ground. It's much easier after that, after all, the ground is not the territory of rats, and these timid guys don't dare to chase out of the subway station at all.

Seeing that the survivors were safe for the time being, Jiao Bai left some summoned beasts to guard the survivors, and he and the other summoned beasts returned to the subway station. This killing, can be described as a very happy killing, summoning beasts using various skills to smash, Jiao Bai burned with a flamethrower at first, and then the flamethrower ran out of fuel, Jiao Bai switched to an electromagnetic rifle to strafe, until the battery power was all gone, and the rat swarm still did not show the slightest sign of reduction. There was no way, Jiao Bai had no choice but to use the merger skill, fused a Rui beast, and began to use the ground thorn skill to attack the mutant rats that besieged him. It's also strange to say that these mutant rats didn't pay much attention to those summoned beasts, and specifically attacked Jiao Bai, as if they understood that those summoned beasts were summoned by Jiao Bai.

Although he had some doubts, Jiao Bai didn't think much about it, anyway, these rats couldn't break through the defense of the intermediate energy shield, so it was better to let them go, and they were all around him, which was more conducive to gathering fire to destroy them. This time, there were many more mutant rats gathered by the Golden Retriever Rat King than Jiao Bai expected, from midnight until dawn, the mutant rats around were still surrounded by three layers inside and three layers outside, and there was no sign of reduction. Later, the space in the subway station was filled with the corpses of mutant rats, and Jiao Bai had to move the battlefield to the subway passage.

It was almost noon when the rats were finally scarce, and the gaps between the rats could already be seen, and after a wave of killing, the replenishment was not so timely.

"Squeak squeak-" With an incomprehensible mouse call, the mutant mice in the subway passage who had not yet come forward were stunned for a moment, and then turned around and ran, no longer having the momentum of being afraid of death before.

Jiao Bai didn't pursue these deserters, but sat on the ground, even if the ground was full of dead bodies and blood of rats. After nearly twelve hours of killing, Jiao Bai was indeed tired, not physically tired, but mentally exhausted. Whoever does the same thing for more than ten hours will feel tired all the time, not to mention that Jiao Bai is still facing a group of mutant rats that look extremely disgusting, and he has not vomited until now, which is already his endurance.

Open the system panel, and the energy value column has exceeded six figures, reaching 1.03 million. These ten hours of killing were not in vain, and the energy value accumulated reached more than 200,000. In this way, the rat tide was at least 150,000 rats killed by Jiao Bai and his summoned beasts, a number that could scare a survivor to death. With an energy value of more than one million, he can finally be promoted to level five, this day Jiao Bai has been looking forward to for a long time, but the environment he is in now is not safe, and it is not the time to advance.

The only thing that made Jiao Bai regret was that he had killed so many mutant rats, but he didn't see the Golden Retriever Rat King, and he didn't know where this guy was hiding. Let it wander around outside alive, Jiao Bai is always uneasy, there are one and there are two, it is difficult to guarantee that it will not gather a larger swarm of rats again. Fucheng's subway lines extend in all directions, and who knows how many mutant rats are hidden in them, hundreds of thousands, or millions. If all of them are gathered, Jiao Bai will also be stunned.

"Meow-" At this moment, on the pile of rat corpses behind Jiao Bai, the ocelot dragged a huge golden retriever mouse over with its mouth. Jiao Bai followed the prestige, and was immediately happy, wasn't it the golden retriever rat king who was held in the mouth by the leopard cat. It's just that the golden retriever rat king at this time, the image is too miserable, not only broke one hind leg, but even the two front legs are all short by one section, looking at the bloody wound on it, it is obvious that he has just been bitten like this by an ocelot.
