After taking their seats, the two sides first said a few polite words, and then Captain Wang led the topic to the metal crystal nucleus.

"Hey, we have some of this kind of crystal nucleus here recently, and others don't use it very much, don't you remember that you have looked for this thing before? You see, how much do you need to change? Captain Wang said to the two with a smile and opened a box in front of him.

The two of them looked at each other in surprise - most of them were second- and third-level metal crystal nuclei, and there were quite a few of them! It's more than they usually get from going out to fight zombies once, how could Captain Wang come up with so much?

After thinking about it for a while, Yan Fei picked up one and looked at it carefully, making an inspection - it was only after repeated research that he determined that it seemed that in addition to him, ordinary people with abilities had to directly contact the crystal nuclei themselves to determine whether these crystal nuclei were real and whether they corresponded to their own abilities.

"What are you going to trade them for? Second- and third-order crystal nuclei of other departments, or first-order crystal nuclei or integrals? The two of them were not polite either, and asked directly - there is no doubt that the homogeneous crystal nucleus has a bonus effect on the abilities of the same system.

Captain Wang saw that the two of them were talking very happily, and said with a smile: "Change to other departments, especially the same crystal nuclei of the popular series, first-class crystal nuclei and points are also fine." But if you exchange it for first-class crystal nuclei and points, the number is ...... Maybe you're going to have to lose a little bit. ”

The two of them thought about it again for a while, and took out the crystal nuclei that they had brought with them that they didn't need at home for the second and third grades.

Although they also brought some first-level crystal nuclei and points, it was definitely not enough to eat these metal-based crystal nuclei, so it was more cost-effective to exchange them for crystal nuclei of the same level.

It can be said that except for the abilities of some special systems, the general sales of crystal nuclei in the base are not bad, so Luo Xun and the others took out some crystal nuclei that they didn't need at home to Captain Wang was still happy to accept.

After replacing this pile of crystal nuclei, Luo Xun asked with a smile: "Wasn't this kind of crystal nucleus quite difficult to find before?" I wonder if there will be any more in the future? ”

The smile on Captain Wang's face was the kind of "you know", he squinted his eyes and smiled kindly: "Of course, of course, you have to cooperate often in the future, as long as you need to change, we will definitely not be able to break it here." ”

After hearing his words, Luo Xun and the others were slightly surprised, and simply picked out some clarity and asked: "It seems that it was quite difficult to get it when we came to find it before, and we can only get a dozen or so ...... at most each time" As he spoke, he took out the cigarettes that Team Li had bribed the two of them in the cafeteria a few days ago.

Captain Wang took the cigarette with a smile and then whispered to the two: "Now in the army...... I can't eat these. He sat up straight and said, "We have to find a market, don't we?" ”

That said, it must have something to do with the metal ability squad.

The two glanced at each other again, and seeing that Captain Wang didn't want to say anything more, he said a few more polite words, and made an appointment to contact him if needed in the future before getting up to say goodbye.

After the two left the barracks, they whispered together and discussed—"There are only two metal adepts left in the military now...... I think it has something to do with this? ”

Yan Fei nodded slightly and groaned: "Actually, the military is not as effective as cleaning up zombies when the weather is warm before, otherwise maybe he can take out more today." ”

“…… But generally speaking, don't all the crystal nuclei of the same system have to be allocated to the relevant teams? Even if the people in the metal ability team can't use it, there won't be so many......"

"Now that Captain Guo is in confinement, it is impossible to contact him in the short term, and the others ......" Yan Fei shook his head slightly, "Let's go back first, since we can change the metal crystal nucleus, we can change it first, the metal ability team will definitely be useful there, don't worry." "No matter how Captain Wang managed to get so many metal-based crystal nuclei, they must at least ensure the supply of homogeneous crystal nuclei from the metal ability team.

In fact, if you calculate it seriously, there are only two people left on the metal team's side, and even if the two of them rotate continuously twenty-four hours a day, there will be a certain upper limit on the number of crystal nuclei consumed, so it is very possible that they will be richer after two less...... Right?

However, after the crystal core change was over this time, both of them only had the same thought in their minds - they had to get out of the city quickly! Otherwise, the crystal nuclei stored in the house will be replaced, and if there are metal crystal nuclei, they can only watch, but they can't exchange their own things, which is really unbearable.

That night, when Li Tie and the others went home, they heard that Luo Xun and Yan Fei were going to get an electric sled out of the base, and they were very excited.

Han Li complained, "Hey, wouldn't it be enough to send us a message during the day if you want these materials?" We'll be able to get you out and bring it back during the day today. ”

Yan Fei smiled: "After all, I asked you to find something in the base database, if the text message sent is seen by others...... Now all the information and phone records in the base are in the hands of the military......"

After hearing his words, everyone became solemn and nodded again and again: "That's right, it's better to be careful if there are any important things in the future, so as not to get any situation, otherwise it will not be good to be heard." ”

Be vigilant and careful, although it will be a little troublesome, but it is much better than being caught by the tail in everything.

Facts have proved that Luo Xun, who has lived a lifetime, has transformed and made many tools in the last days, plus a metal-based ability that can handle any metal, extract any metal, and make any shape, the power of the two is still very great.

After the two of them got the relevant information, they tinkered for a day to build a sample single metal sled, on the roof of their own building - yes, that's right, on the roof of Building 7 - anyway, there are usually no people here, and the geographical location is high, so there is no problem if the equipment can run or not. Moreover, although there was not much snow on the roof, there was still light snow in the sky when Yan Fei cleared the snow that day, and a thin layer fell on the roof afterwards, so Yan Fei didn't bother to clean it up.

In short, after the two of them realized on the roof that the simple metal sleds could indeed drive normally, carry people, and carry goods, they directly made four large metal sleds that could be ridden by everyone.

Although the speed of self-modification is a little faster because I can't find a professional engine, at least it can carry people, load things, and run on snow. In order not to "treat others differently", Luo Xun and Yan Fei discussed it, and directly disassembled the finished sleigh into parts and put them into their own cars. When you leave the base, drive the car out, completely lock the car with a metal ability or transform it into a rotten car that no one wants, and throw it anywhere, and then ride the metal sleigh into the city to shoot the crystal core.

After making all the preparations, preparing all the things to bring when going out, and wearing all the equipment to wear when going out, in the early morning of Li Tie's first day of vacation, the otaku team set off again.

After driving out of the gate of the base, Luo Xun and the others had a little headache, although the road surface within a distance of the small broken river that had frozen at the gate of the base had been flattened by the military vehicles, tanks and other things that had left the base before, but it was obviously still closed by heavy snow in the urban area, and it was sealed exceptionally strongly.

It's no wonder that the staff at the base looked at their dilapidated cars with great surprise before they went out just now - there were no professional vehicles to go out in this weather, either hungry or stupid.

In order to bring gasoline, mushroom juice, weapons and ammunition, and a modified metal sled, Luo Xun and the others finally drove three cars.

After barely driving some distance, they had to get out of the car and start assembling their metal sleds. There is no way, the road after that is really not able to go by car.

After opening the car door, everyone was struggling to find that their shoes could sink into the snow after they got out of the car! This is still the place where other vehicles have been crushed, as for other locations...... Hehe, it's better not to try lightly.

After quickly assembling their "sleds" and moving their things to the sleds, Yan Fei rebuilt the three cars into scrap metal and threw them on the side of the road. There are quite a few cars of this shape on the side of the road, and not many people will take a closer look at the post-apocalyptic team passing by here.

For safety reasons, they even threw a lot of snow on the car, dressing it up as a tattered pile buried in the snow.

Climbing on the sleigh, putting on thick hats and masks, and pulling up the collars, Luo Xun and Yan Fei and Li Tie sat on the first sleigh, followed by the combination of He Qiankun and Wu Xin, followed by Xu Mei, Song Lingling, Xiao Xinran, and the last car was Wang Duo, Zhang Su and Han Li. He Qiankun's tonnage is relatively large, so ...... Ahem, they have the least number of people in their car.

In addition to people, there are also materials loaded by everyone on each sleigh, so the volume of the car itself is actually quite large.

After stringing the cars together with ropes, Luo Xun and his car headed their way to the south of the city where they had fought before.

It's still collecting metal balls along the way and rolling along the way - of course, this is only after leaving the base for some distance. The speed of the sled is not fast, but it is precisely because it is not too fast that the possibility of overturning is reduced, after all, how much debris will there be in the ruined old city under the heavy snow? And after the heavy snow closed the road, everyone's eyes were white, who knows where the road is? Where are the ruins?

Anyway, they had a lot of ups and downs along the way, and when they came to the place where they had roughly fought the giant duck before, the sun began to tilt to the west.

"Brother Luo, why didn't you see any zombies along the way?" After everyone arrived at the place, Yan Fei first laid a layer of metal plates on the ground where everyone was located, so that everyone dared to get out of the car and stomp their feet on the spot to keep warm - although they had prepared a lot of heating things in advance along the way, they couldn't stand the cold wind blowing for so long!

"It's all in the snow." Luo Xunha let out a cool breath, and as soon as his words fell, something was obviously something in the snow not far away, and then the claws that had been black, dry, thin, and rotten hands that had been frozen stretched out.

"I'm Kao!" Wang Duo screamed and jumped backwards. There's no way, although the speed of this hand is not fast, the movement is stiff, and the zombies below obviously can't crawl out for a while, but this picture is too terrifying, right?

"Clear out the foothold first, it's better for these zombies to bombard directly with their abilities." Luo Xun rubbed his cheeks with his gloved hands, and didn't look at the zombie who was obviously stuck in the snow for a while and couldn't climb out.

“…… So are zombies frozen in the snow on a snowy day? Han Li was stunned for a long time and asked Luo Xun for verification.

Luo Xun thought for a while: "I guess no one has been here since we left last time, so once the snow starts to fall, the zombies who wander to the vicinity probably haven't left the same place...... On such a cold day, even the legs and feet of zombies will be frozen...... Think about it, if their legs, feet and bodies are frozen, they can't walk without external stimuli? ”

Once they fall, do they have something to lead them to get up, or do they have to lie on the ground and wait for the snow to bury them?

"Brother Ro...... You're amazing! Li Tiexing looked at Luo Xun with starry eyes, he felt that his own captain was really worthy of being his own captain, although he could not predict like a waste wood house, but when it came to analyzing these things, he was not a person!

Luo Xun, who is not a person, smiled embarrassedly, and pulled his husband to find the specific location where they used to stay. It wasn't too easy to let Yan Fei come to find it, and after a little probing, he found the metal trap he had hidden before, and when that circle of metal walls was erected, all of them immediately found the target.

Xu Mei's fire-based ability melts the snow and ice that covers it, and Song Lingling manipulates the melted water to move far away into the snowdrift in the distance. The rest of the people shot the zombies that were revealed after the ice and snow melted, and only after their temporary base was completely cleared did everyone drive their small sleds in, and then-Yan Fei began to quickly cap their shelter!!

There's no way, the shadow that the big duck brought to everyone's hearts last time is too big, if they come to this again with half a zombie...... As long as the IQ of the animals that come over is slightly higher, it will definitely be a bad day for everyone!

The metal roof was quickly built, and everyone directly lit a fire in it, and heated the metal "hot water bottle" into their arms - this thing was made before everyone came out, the metal shell, wrapped in water, Xu Mei directly heated them with fire-based abilities, and then wrapped them in thick cloth and held them in their arms, loaded on the seat on everyone's sleigh, and the whole person sat in the heated metal seat, and would not freeze feet and legs. If the temperature drops along the way, everyone will stop and let Xu Mei use the ability to reheat.

Now Yan Fei has come up with another kind of thing - a metal hot water sofa, which is filled with water, and the whole "sofa" is gathered around the fire, using the fire to warm the water in the metal.

This kind of handy thing can only be made when there are water, metal, and fire abilities in the team at the same time, and it is simply easy to use.

After getting the warmth in place, it was still Xu Mei's fire-based ability that melted all the ice and snow on the trap, and Song Lingling transferred the snow water. That's when we all started to prepare for today's work.

The mushroom juice they had brought along the way was itself frozen, and now it was frozen hard, except for some of the melted by their metal "plumbing cushions".

Thankfully – the gasoline didn't freeze.

Placing the box containing the mushroom juice next to the fire to thaw, Yan Fei began to sort out the ground thorns and other things in the trap, Xu Mei and Song Lingling put the melted mushroom juice into the metal box near the trap.

In winter, the wind and snow outside are too big, and Xiao Xinran's sand-based ability is useless for the time being, so he obediently sits on the sidelines and watches everyone busy. After Yan Fei's preparations are almost done. Luo Xun took out the blood bag, hung it outside and began to attract monsters.

"It is estimated that it won't be long before the blood bag freezes, Song Lingling, you manipulate the hot water to circle around the metal box outside a few times every once in a while to ensure that the blood inside remains in a melting state." Luo Xun observed the situation outside and ordered, and then said to everyone, "Okay, let's get ready for dinner." ”

"Weird ...... Outside"

"It's not so fast, even if there are mutated zombies that can move in the snow and are not frozen, it will take some effort for them to rush over, let's eat first." Luo Xun is very calm, even the zombies are inconvenient on this snowy day, as long as God doesn't deliberately get along with everyone and it snows heavily, as for the blame...... In winter, take it slowly, don't be in a hurry.

The zombies' movements are stiff and sluggish, and each movement is like a slowed down in a movie. Luo Xun and the others ate and drank enough, occasionally looking around at the small window with a leaky air, and Song Lingling manipulated the heated water from time to time to circle around the box with blood outside to keep the blood melting.

Zhang Su also manipulated the wind every once in a while, and with the obvious smell of blood, it spread in all directions, and those smells mixed with the winter north wind slowly drifted into the distance.

"Well, it looks like another batch is coming." Everyone took turns to go to the vicinity of the small window from time to time to see the situation outside, now that the sky was a little darker, they didn't attract many monsters for a whole afternoon, most of these zombies moved slowly when they came, even if some of them were relatively fast, they fell into their trap after arriving.

For the sake of efficiency, Luo Xun and the others spent an afternoon renovating their fortification, and now they have a bunch of plumbing pipes under the trap, which has the same effect as the plumbing floor they have renovated in their home, of course, these things are much more rudimentary than the plumbing they use at home.

And the only effect of these things is to keep the mushroom juice at the bottom of the trap in a melted state, so that if a zombie drops it, it can be corrupted by the mushroom juice. There is also a row of leaky pipes above the inner side of the trap, which drops the mushroom juice into the pit at a slow speed, causing the zombies to flank up and down.

This time, they brought out a lot of mushroom juice, and the zombies who rushed over nearby all afternoon were slow to move, and even zombies with abilities often were corrupted by these mushroom juices after falling into this place before they could attack with their abilities a few times.

"Is it a lot?" Hearing this, Luo Xun leaned to the window and looked out, there were many black shadows in the ice and snow that were slowly moving towards everyone's location, looking at the black oppression, Luo Xun touched his chin, "It seems to be the kind of physique zombie that has become a lot bigger." ”

"What?!"

"Where? Where is it! ”

Obviously, everyone was already a little sleepy and confused because of boredom, but after hearing this, they all rushed over one by one full of energy.

"Don't crowd, they'll have to walk for a while." Luo Xun gave up his place, stretched his waist and yawned, shivered after feeling a light wind blowing in from the window, and hurried back to the fire and the seat filled with hot water to warm up.

The roar was getting louder and closer, Li Tie and the five of them were very nervous, and even the expressions of Xu Mei and Song Lingling became solemn.

Xiao Xinran roasted the fire, ate the strawberries that were washed and brought out in the morning, ate one, looked up at everyone, and ate another one.

When Li Tie at the window had already subconsciously raised the modified crossbow and was ready to realize the power of the new weapon at any time, Xiao Xinran suddenly pulled Luo Xun's arm.

"What's wrong?" Luo Xun looked down at the little girl, Xiao Xinran looked at the strawberry in his hand again, and then looked up and asked, "Why can't we take the little guy with us when we come out?" ”

Usually, when Xiao Xinran eats snacks and fruits, she is mostly with the little guy, and most of her fruits are eaten separately from it. So as soon as she ate the strawberries now, she remembered the dog who couldn't come out.

Luo Xun smiled bitterly and stroked her hair: "Wait tomorrow we can go back and eat with it, it's too dangerous outside, the little guy can't understand what we say, if you accidentally eat something outside, it's dangerous." "Dogs are not people, people know to be careful when they come out, and they can't touch some dangerous things, but dogs are different, if they accidentally lick something, rub something dirty, they will be zombies...... When the time comes, it will be too late for everyone to cry again.

Luo Xun can't tell his current mood, although the little guy has a certain chance of mutating after the beginning of spring next year, but if it doesn't change, or if the mutation fails...... If it hasn't changed, the little guy will still be the same as it is now, they still don't dare to release it, is such a life fortunate or unfortunate for it? If he thinks about it that way, he may have made the wrong decision to buy it back in the first place...... But if you hadn't bought it, would it have mutated by now?

The brain unconsciously began to wander, and suddenly there was a cheer in a low voice from the window: "Hit, hit!" ”
