Inside, the fierce gunfire grew louder and louder, and sparks from the muzzles of the guns even lit up the combat area. Zhou Xin, www.biquge.info of the pen, fun and pavilion, walked to the place where the battle was most fierce and looked ahead, and found that the prairie rats were still rushing forward one after another as they were yesterday, and the corpses on the ground were already more than half a person high, and some of the prairie rats had even begun to gnaw on the corpses of their own kind.

"Let's not rush forward for now, let's focus on eliminating their numbers." Zhou Xin said to B-001, "Don't care about the consumption of ammunition, according to the fertility rate of those little guys, there is not enough to destroy them without enough speed to stop their numbers from growing, besides." Zhou Xin turned his head to look at the engineering robot G-101 on the other side, "Try to clean up the corpses of the prairie rats in front, I don't want these corpses to provide nutrients to those guys." ”

The engineering robots that had brought in the ammunition turned around and walked towards the front line of the position, and after a while, they saw the robots walking out with the corpses.

The battle lasted for more than five hours, and the engineering robots transporting the ammunition did not know how many rounds had changed, but the number of prairie rats rushing over did not decrease. There was a heavy smell of blood in the air, Zhou Xin wiped his nose, "This smell is really unpleasant, host, count how many prairie rats have been eliminated, a million of these things, when will it be finished." As he spoke, he fired two more shots.

"According to statistics, we have eliminated more than 300,000 prairie rats, and the number of rats detected by the detector is decreasing, but according to the analysis of rat corpses brought out by engineering robots, prairie rats are evolving, and their muscles are gradually becoming stronger, especially the bite force of their teeth, which should be paid special attention to."

"It's still evolving, although I can't see any special effects yet, but just in case, it's better to fight quickly. Voyager, can you use grenades to attack? Zhou Xin thought for a moment

"Analyzing...... It is allowed, but be careful not to damage the surrounding bulkheads, and do not use it under the large tree, if the tree falls, the part of the ceiling it supports may follow the fall and deal secondary damage. The Voyager replied after a moment's analysis.

"Understood, B-001 is now allowed to attack with weapons such as grenades, be careful not to blow up the bulkhead and that tree, speed up the destruction of them, these prairie rats are evolving." Zhou Xin turned his head and ordered to the B-001 that was shooting next to him.

"Understood, use grenades, use more efficient methods to destroy the enemy." B-001 replied, "Execute Combat Plan B, change the combat form." ”

At this time, Zhou Xin saw that some of the combat robots dropped the guns in their hands, and then stretched out a two-meter-long high-strength alloy knife from each arm and leg, and then walked towards the rushing rats step by step, when they came into contact with the rats, they all turned on their jet devices, so the robots with knives charged back and forth in the rats, setting off a bloody storm, like entering a no-man (rat) realm.

"Advance with them, and the engineering robots will dispose of the rat corpses after they are broken, and destroy them as quickly as possible." Zhou Xin ordered.

The rest of the robots immediately picked up their guns and advanced step by step, and from time to time some robots threw grenades into those dense swarms of rats, and Zhou Xin found that the speed of eliminating the rats began to accelerate.

About 50 meters away from the big tree, the rat swarm began to be more dense, countless grassland rats even rushed towards the robot position like a tide, and the melee robots that opened the way in front were all flooded by the swarm of rats, and at this time, the robots behind were not like at the beginning to mainly use assault rifles to attack, most of the robots began to lose grenades, but they still couldn't stop the rat swarm's charge, and some even rushed through the blockade and rushed towards Zhou Xin.

"Steady, engineering robots come up to help." Zhou Xin didn't dare to use a grenade behind the robot, so he could only hurriedly shoot and retreat, while ordering the engineering robot behind him to come up and help.

After more than ten minutes of scrambling, Zhou Xin successfully cleared the fish that rushed over with the help of engineering robots. And the battle robot in front of it also successfully stabilized its position, once again blocking the rat swarm. However, it was only blocked, and a steady stream of prairie rats continued to impact the blockade line of the robot, and the situation was stalemate for a while.

"It looks like there's no way to move on, so let's hold on first." Zhou Xin said helplessly, "This wave of attacks has wiped out more than 100,000 of them." However, there are more than 600,000 of them, which is a real headache. ”

After about five or six hours, Zhou Xin had become numb when he killed the rats, and he also found that the size of the rats began to gradually increase, the grassland rats were only about 20 cm long at the beginning, and now they are basically 50 cm, and even some large ones have reached 70 cm in length, Zhou Xin can't help but be a little worried.

"Faster, faster, at a faster pace, if you continue to evolve, you don't know what to give birth to. Voyager, analyze the current situation. Zhou Xin's voice was a little anxious.

"The battle has been going on for 11 hours and 13 minutes, and more than 938,000 prairie rats have been eliminated, and more than 150,000 prairie rats are expected to be exterminated. Compared to the beginning of the battle, the prairie rat has increased in size by about three times, increased in strength by about eight times, increased aggressiveness, increased desire to attack, and even began to have simple tactics when attacking. In terms of combat robots, after a long battle, the parts of some robots have begun to be damaged, especially melee weapons, and now some engineering robots are transporting weapons to temporarily repair combat robots, and as the battle progresses, the damage to robots will become more and more serious. The Voyager was silent for a moment, then replied.

"It sucks." Zhou Xinzhong was cold, "Don't clean up the corpses first, call the engineering robots to come up, give priority to repairing the combat robots, our number is not much, if the number is reduced, there is really no need to fight." Zhou Xin hurriedly ordered.

The battle lasted for more than an hour, and during this time, the consequences of the long battle began to be reflected continuously, with combat robots constantly cutting off their weapons, gun barrels exploding, and even some robots stopped directly due to being soaked in blood for a long time. At this time, the engineering robots dragged these robots back from the battlefield for repairs, and even so, there were still some damaged robots that withdrew from the battlefield because they needed to be overhauled. Zhou Xin found that their efficiency in killing rats began to decrease, and Zhou Xin felt a little helpless about this.

"It is reported that the evolution of prairie rats has accelerated in the past hour." At this time, the Voyager sent new news, "The rat colony has evolved stronger individuals, some of which have evolved the strength of an adult male. ”

Zhou Xin said helplessly, "It's really troublesome, is there any way to slow down their evolution." He also discovered the trend of the evolution of the rat swarm, but there was no better means to do it now, "It would be nice if there were more people, alas, I wouldn't have expected that I was the only one at the beginning, so the combat robots were only built a little bit as a supplement, and now it's still not enough, so let's build more robots when this battle is over." However, he also found that although the grassland rats that rushed over were getting stronger and stronger, their numbers began to decrease significantly.

"The rat population is expected to be 70,000 more." A message from the Voyager came from the communicator.

After another hour, Zhou Xin and the robot had pushed the battle line to about 30 meters away from the big tree, Zhou Xin found that the prairie rats were originally drilled out from under the trees, and at the same time, he also found that there were fewer prairie rats coming in, but each of the prairie rats rushing over was the size of a calf, and the charge of two or three prairie mice could even knock down a robot. On Zhou Xin's side, more than half of the combat robots have also been lost, less than 500 units.

Zhou Xin thought for a while and ordered: "The melee type is back and uses long-range weapons to fight, the engineering robot is on top, and the grenades are not used, all of them are shot with guns." With that, the engineering robot rushed forward with a screwdriver and a wrench......

When the shipborne host reported that all the rat swarms had been successfully eliminated, there were less than a hundred combat robots left around Zhou Xin, and at the end of the battle, the evolved steppe rats could even bite off the alloy barrel, which really scared Zhou Xin, he hurriedly retreated the battle line to stabilize, and the combat robots also suffered the most losses at this time, and there were about 200 robots that were bitten off different parts in this rat swarm charge and withdrew from the battle. However, they had the last laugh and succeeded in eradicating all the prairie rats. According to statistics, this rodent war lasted more than 14 hours, and a total of no less than 1.2 million grassland rats were eliminated, and the side lost about 1,000 combat robots and more than 700 engineering robots.

Zhou Xin, who was tired and hungry, was nibbling on a baked cake, and breathed a sigh of relief after hearing the Voyager's report, "It's okay, it's finally over, we won't be able to hold on if we continue to fight, more than a million, I feel terrible when I think about it, okay, it's time for us to see what's weird about that tree." He finished the last bite of the pancake and walked towards the tree with the two battle droids.

Walking under the tree step by step, Zhou Xin found that the tree was much more majestic from a close distance than from a distance, the complex roots were intertwined with each other and extended far away, just now a lot of grassland mice were drilled out from between the roots of the entangled, deep and shallow feet along the roots to the trunk, the thick trunk in the field of vision is getting bigger and bigger, when Zhou Xin really walked to the side of the trunk, the thick trunk actually became a wall, it is completely impossible to see that this is actually the trunk of the tree, limited by the height of the ecological cabin, the tree did not grow much taller, But it grew very luxuriantly, standing under the trunk of the tree and looking up, the luxuriant branches completely blocked the light on the roof of the cabin, fortunately there was the light of the engineering robot, otherwise it would be really dark here, looking along the light, there were obvious burnt marks on the trunk, Zhou Xin walked to one of the black traces and stopped.

"Traveler, check the condition of this tree." Zhou Xin stroked the trunk and said. A detection robot comes up and extracts some wood chips from the trunk of a tree and drops them into its stomach.

After a while, the voice of the Voyager came from the communicator, "The preliminary analysis is complete, and it is determined that this tree species belongs to the Ficus genus, with a lifespan of about 100 years, and the cell division rate is at least twice as fast as that of normal Ficus plants." When the cells catch fire, they secrete resin-like objects to extinguish the fire, which is why the tree survives, and the other physiological structures are not much different from other Ficus species. ”

"Looks like it's the type of creature that overgrows." After listening to the traveler's report, Zhou Xin thought of the abnormal condition of the plants in the other eco-cabins.

"Di, Di, detected the existence of unknown life." At this time, the detection robot behind Zhou Xin issued a prompt. Zhou Xin suddenly became nervous, "What, there is still something there, doesn't it mean that it has all been wiped out." What is it, by the way, I haven't found the existence of the rat king until now, is there really a rat king? "The detection robot has detected a weak life signal, and according to the signal strength, the probability of being an adult is very small." Voyager replied. "Where, take me to see it." Zhou Xin breathed a sigh of relief.

The detection robot raised the detector in its hand and searched for it on the trunk, and after a while, it walked along the trunk in one of the directions, and Zhou Xin hurriedly followed. After walking about ten meters along the trunk of the tree, about a meter above the ground, the robot pointed the probe into a tree hole.

Zhou Xin looked towards the tree hole and saw a small thing lying in the tree hole, it was a newborn little prairie rat, its eyes had not yet opened, its whole body had not yet grown hair, and its pink skin was really cute. Zhou Xin was slightly stunned when he saw this little thing, "This is the Rat King?" No way. He thought to himself. At this time, the little thing seemed to sense the movement outside and opened its eyes. The first thing it saw when it opened its eyes was Zhou Xin's face leaning on the trunk of the tree and looking into the hollow of the tree. It chirped twice, then climbed onto his shoulder with Zhou Xin's hand on the trunk of the tree, rubbing its head against Zhou Xin's chin and chirping.

Zhou Xin hurriedly took the little guy off his shoulder, and then held it in his hand and observed it carefully. The little guy looked confused at first in Zhou Xin's hand, and after rolling around, he continued to chirp at Zhou Xin.

"What's going on?" Zhou Xin looked confused. "Preliminary analysis, this is a newborn prairie rat, although I don't know why it didn't grow into an adult quickly, but what is certain is that the first thing it sees when it opens its eyes is you, Captain, so it takes you as its mother." Voyager analyzed.

"Don't make jokes like that." Zhou Xin said to the Voyager in surprise. "It's not a joke, Captain." Zhou Xin stared at the little thing in his hand, the little thing was still screaming, Zhou Xin hesitated, "Don't call it yet, although you say that your kind has caused me a lot of trouble, but for the sake of only destroying the No. 2 ecological cabin, it's not impossible to spare you, but you have to be obedient in the future." Zhou Xin said to himself, he didn't expect this little guy to understand his words. However, seeing that the little guy really stopped screaming and nodded at him, Zhou Xin was surprised again.

"Do you understand me?" Zhou Xin asked at the little guy. The mouse nodded at his hand and shook his head. "What does that mean?" Zhou Xin wondered. "It should be able to partially understand your intentions, and preliminary analysis of its intelligence is equivalent to that of a three- or four-year-old human child." The Voyager added.

"Okay." Zhou Xin picked up the little guy and walked to the door, "The problem of the No. 2 ecological cabin should be over, Voyager, send more reconnaissance robots to scan here to prevent the existence of fish that have slipped through the net, as for this tree, prune it a little and move it to other ecological cabins, and the tail sweeping work will be handed over to you." After speaking, Zhou Xin went back to the command cabin with the mouse in his hand......
