"Armed forces, in fact, are still a little bit behind."

Listening to the roar of tongues of fire from the medium-sized electric sentry machine gun platform, Lin Yue saw that the mutated biogroup called "Dorusta" before dozens of heads had completely turned into a tower of dead corpses.

Some of them were seriously injured and did not die, and they had just dragged their bodies to their feet, and they were immediately blown to pieces by bullets!

"Not bad. However, is it a bit bullet-consuming? ”

Lin Yue walked in front of the machine gun that had just attacked the mutant creatures, and its barrel was now hot!

He looked at the number of bullets that had just been fired.

"123 rounds, indeed, a bit too much to deal with more than twenty of those mutant creatures."

Look at the one on the other side, 82 rounds.

The firepower crossover network is really hilarious, both audibly and visually, it can make people feel an ultimate enjoyment.

But the bullet is much less efficient at shooting.

The medium electric sentry machine gun mount is not without weaknesses, and it can even be said that there are many of them.

Under the continuous firing, the shooting accuracy of the bullet cannot be guaranteed, and the consumption of this bullet just now is proof.

Secondly, the penetration of its bullets is still quite limited, and when it encounters harder ones, it can only rely on bullets to kill the opponent.

One of the most lethal of all is the magazine.

At present, the ammunition magazine that can be stored is about three or four thousand, and it can be seen from the attack just now that one attack will cost more than 100 yuan, and if there are ten such attacks a day, the magazine will have to be replenished once in about three days.

And that's when the number of enemies is small.

If more than 10,000 lizardmen line up to attack, a wave of crowd tactics will come......

I'm afraid that these medium-sized electric sentry machine guns will run out of bullets in the magazine in a very short time, and completely mute the front lizardmen after killing them, and completely become decorations.

It's not that the magazine can't be upgraded.

But the downside is that he also has to spend nitrocellulose to make bullets to replenish these magazines.

And nitrocellulose cotton, there are really not many now, there are really not much.

Nitrocellulose is a thing, it seems that at present, the only person who can give it to him is Xing Lingfeng, and this Xing Lingfeng is very likely to be the Xing Lingfeng that the first generation of survivors said.

After all, many things before and after are completely consistent, and the truth is explained clearly, and basically there is no running.

But this Xing Lingfeng seems to be the only one in the entire world channel who can supply him with nitrocellulose.

"I don't know what I've guessed at the moment, but nevertheless, the trade or something should still be traded."

Lin Yue stood on the city wall, opened the system panel, and looked at the world trading channel first.

Before, he put vegetables, grass carp or something in exchange for the precision electric actuator that the robot dog needs, and after a while, I don't know how much the quotation will be?

However, I don't know if I don't see it, and I was really shocked when I saw it.

"That's a lot of people who have this thing." He couldn't help but sigh.

I have to say that vegetables and grass carp are quite popular, and in this other world, there are still not many people who can eat vegetables.

[You have obtained the precision electric actuator X109!] 】

With the disappearance of grass carp and vegetables in his storage space, he has more than enough of the most important materials necessary to make 109 robot dogs!

"Haha, although I expected a lot, the materials I brought this time are only enough to make 40 robot dogs."

Lin Yue felt that this was really a bit of a happy trouble.

Robot dog, he believes that there should not be a second person among the survivors in this other world besides him, but at present, his scale has reached a high capacity of 120 heads!

Now, another 40 robot dogs will be produced soon......

This wave, Lin Yue felt that it had stabilized.

These 160 robot dogs, if he can, can drive them to directly attack any of the vault villages in this world, and then kill everyone within an hour......

Although, he didn't want to.

After all, there is no point.

Unless the other party takes the initiative to provoke him, otherwise, Lin Yue, who is afraid of trouble, will still use these robot dogs as one of the main forces of defense and defense.

Of course, they will also be used in battles against lizards and beggars, and will be quite active.

Glancing at the storage space, Lin Yue opened the dialog box with Xing Lingfeng again.

"Xing Lingfeng, I need nitrocellulose here, how much do you have?"

Judging from the previous transactions, Xing Lingfeng's refuge village is not short of ordinary food and general daily necessities, and he is quite fond of things like wine.

And wine is precisely one of the resources that Lin Yue wants to sell the most at present.

The reason is that he has too much inventory.

Whether it's wine or whiskey, he has a lot of reserves, and because he really hasn't traded them for anything lately, he's been trading saltpeter and the like for resources.

Now, it seems to be just right.

However, after Lin Yue sent out the conversation, Xing Lingfeng didn't have any reaction for a long time.

Busy? Or rather......

Lin Yue remembered that Xing Lingfeng had deliberately pitted him and Lily Karahao against each other, wanting them to tear them apart.

Could this thing be doing something else?

Lin Yue waited for a while, and after not responding continuously, he walked down the city wall, opened the alloy gate, and came outside the city wall.

About ten meters away from the city wall, Lin Yue started construction again.

This time, however, he built a 35-centimeter-thick, three-meter-high wall that didn't need to be defended by a sentry machine gun emplacement, just a height of the first one.

Around the city wall, Lin Yue quickly built a new circle of walls, and within the scope of this wall and the city wall, as well as the other side inside the city wall, was also paved with a layer of stones.

The main purpose of this is to prevent lizardmen and beggars from digging holes in this area and attacking from within.

After doing this, Lin Yue put out the remaining 20 robot dogs from before

Moreover, Lin Yue also added a sniper rifle to each of these robot dogs to upgrade separately, and the number of bullets was 30 rounds.

The sniper-type robot dogs are very useful, and Lin Yue also believes that they can easily shoot the enemy in the head at a very long distance!

In order to make it easy for them to snipe, Lin Yue also set up some slopes between the outer city wall and the ground for moving up, so that these robot dogs can patrol and snipe directly!

Lin Yue set up and edited their patrol routes and strategies when encountering enemies one by one, which took a little time.

After that, he built 40 robot dogs non-stop!

These dogs are equipped with twin MP5 submachine guns, and are responsible for short-to-medium range sweeps and guerrillas when the medium electric sentry machine gun is under silent fire, or when it is broken by the lizardmen.

In this way, with the dual cooperation of the medium-sized electric sentry machine gun platform and the robot dog, there is basically no problem with the defense of the short, medium and long distances.

"All that's left is to build the Doomsday Bunker and go back and bring the Xiaoice lizards over, then ......"

At this moment, the system suddenly made a sound!

[Congratulations, you and your pet have developed an emotional bond, and your pet has evolved a bond!] 】

Well? Evolved? Who?

[Congratulations, you and your pet have developed an emotional bond, and your pet has evolved a bond!] 】

……

Ahh

What's the situation, how did these two lying flat little lazy people upgrade?

And, is it still a stumbling evolution? What did I do to me? It's obviously dozens of kilometers away from the saltpeter mine, right?

Lin Yue, who felt strange and surprised by this, looked at the racial information of these two little guys, and probably guessed the state of the two of them.

Even if you don't see these two, you can tell that one should run for land and the other fly in the sky.

It's like Xiaobai and Xiaomeng, just like Xiaoliuzi and Hongxian, they all evolved in pairs like this.

Flying specializations will have some speed and attack bonuses, while land running is very good in terms of resistance to hits and physical strength.

However, there are also problems.

"Xiaobai, Xiaomeng, Black Spot, Green Claw, Little Liuzi and Red Line, there are actually six evolutionary branches? Evolution alone is already outrageous, and there are six evolutions? Then there are five hundred remaining Xiaoice lizards, isn't there five hundred evolutions? ”

Lin Yue still has a lot of incomprehension about this world, especially the evolution of a creature like an ice lizard, which makes him completely confused.

After all, there will be no evolved creatures on the earth, and there are butterflies that are transformed into butterflies, and that is also insects and the like, but no matter how the Xiaoice lizards look, even from the name, they are also crested reptiles.

But exactly, they are evolutionary, except for the black spots and green claws, he has not seen them with his own eyes, Xiaobai Xiaomeng, he has witnessed them almost all the time.

After two consecutive evolutions, there is also a state called "molting", but at present, only Xiaobai has done it, Xiaomeng has not seen any signs yet, and there is no similar situation in the other.

Onigiri reads a book

"However, it seems that there can be three players who can fly, and it seems that there will be more tactical options in the future."

Lin Yue was not dissatisfied with the evolution of the black dot and the green claw, but he had no intention of inserting willows into the shade, and there were indeed some accidents.

He really wanted to know how these two little guys made up their brains to make up for a bond evolution, after all, all the previous bond evolution was because of a "special opportunity".

For example, Xiaobai's first evolution was because after accumulating a lot of combat experience in several actions with him, and after living together for a long time, the relationship became more intimate, and finally evolved.

And only the second bond evolution of Xiaobai and Xiaomeng is really related to "mutual rescue in crisis".

Xiao Bai was unable to fight because he fell into a coma due to a high fever, and Xiao Bai stepped forward to kill a lot of enemies before he successfully evolved.

Xiao Meng ran to the underground ruins, in order to cover the black spots they were attacked by the lizardmen's explosives and were seriously injured, he spent a lot of effort to save Xiao Meng's life, and went to the underground ruins for it to take revenge.

And the black dot and the green claw, it is true that they have been with him for a long time but have not evolved, although they were a little concerned before, but they really felt that they couldn't force it.

Xiao Meng and they all came together, and they have evolved twice, and Xiao Liuzi and Hongxian have always acted together with them and have also evolved, so these two are also a little anxious.

And to bring them to the saltpeter mine and let them face many enemies alone, I'm afraid these two may have made up for this special task or something, so they evolved.

"That being said, I'm really happy that they've evolved. Xiaobai, you first take refuge in the shelter, help me bring twenty Xiaoice lizards over, remember to add the red line inside. ”

"Quack." Xiao Bai had just gone outside this wall to play the game of mutant creature hunting for half a day, and after hearing Lin Yue's order, he immediately rushed into the sky and flew in the direction of the main refuge.

And Lin Yue walked outside from the alloy gate of the second wall, nearly two kilometers away from the oil extraction and refining platform, and stopped at another position opposite to the original doomsday bunker.

This side is a small rolling hill, which has also been covered with weeds.

It is true that I haven't seen a few mutant creatures around, and they all seem to have been beaten half to death by Xiaobai and piled together.

"Xiaobai is still playing quite excessively, it is estimated that there will be no mutated creatures within three or four kilometers, right?"

Lin Yue walked in front of those mutated creatures that were still breathing, and took out the excellent iron spear.

Putting on the mechanical arm, Lin Yue effortlessly gave them a happy dog leash.

"Sixty-seven, not bad." Lin Yue did not dissect them directly, but directly loaded the corpses of these mutated creatures into the storage space.

There's a lot of use after that.

Forty-two iron treasure chests, thirty-five copper treasure chests, plus the previous one hundred and thirty-seven copper treasure chests, and two silver treasure chests, this is another treasure chest that has not been opened.

It seems that Xiaobai can finally experience the feeling of opening a treasure chest and vomiting.

"There doesn't seem to be a problem around here, so ......"

Lin Yue looked at the design diagram in the system panel.

Doomsday Bunker.

A name that, to be honest, isn't too likable.

Doomsday, what is Doomsday?

After 100 million people crossed over, almost all of them died in the "end of mankind" in this unknown other world?

So, is the second "human apocalypse" for the second time when all seven billion people have traveled to the same other world together?

Lin Yue didn't agree, and he would never let this happen.

Although he doesn't want to be the hero who saves the world, if necessary, he will also destroy all the enemies who will push all mankind to the end when necessary, as the most powerful person in this world!

Lizardmen and beggars, for example!

"Doomsday Bunker, although I don't like the name, but speaking of which, its appearance is actually quite scientific, and it is quite suitable as a safe fortress in this kind of wilderness, but it can indeed be transformed."

Lin Yue said, using this design drawing, and at the same time, a large number of stones in the storage space also disappeared at the same time!

Make a stone one, then upgrade it and fully alloy it!

If you want to do it, you have to do it to the best of your ability.

The previous Doomsday Bunker, only the entrance, corridor, and first floor were alloyed, and the next floor was made of stone, which was actually not perfect.

Otherwise, it wouldn't have been invaded by those mutant bugs through the cracks, and it would even be able to connect to the underground ruins in the end.

However, the settings of each room are actually quite scientific, although some are considered to be a bit of a painting, but the vast majority are still acceptable.

The white light slowly bloomed under his feet, and at the same time, there was a burst of roar!

Soon, as the light fell, an entrance appeared in front of him that looked like a well like before!

……

Tomorrow starts 10,000 shifts, a week!
