The elite jewels in insurance are found in the heads of zombies that have grown stronger and faster. Some people call this thing a crystal nucleus, and it's rumored to level up abilities. After discovering these things, the volunteers confirmed that they could indeed serve part of the rumored role - they could replenish the mental power consumed by the use of the ability.

But are there any side effects associated with this kind of thing? Will there be other effects? Will using too much make people lose their minds and become zombies? It is unclear that experts and scholars from scientific research institutions in the base are intensifying their efforts to study this project.

And what these soldiers who go out on a mission to do is to destroy and bring back this "crystal nucleus" as soon as they find a zombie that may appear in this "crystal nucleus".

"Chief! There are two private vehicles in the convoy that joined later! ”

The man gave the order with an impassive face: "Leave one maintenance car behind, and the other vehicles will continue to drive." "Their convoy is too large, and they don't know how many zombies they have smelled along the way, and they have to hurry back to the southwest base. Many of the people in the convoy were rescued and had to bring two important pieces of information back to the base - first, the reason why the three broken bases had problems was because the water source was contaminated by the zombie virus! Second, the number of zombies with crystal nuclei in their brains has proliferated, as if all ordinary, slow-moving zombies have almost disappeared overnight, and everyone will face those mutated high-level zombies in the future!!

――――――――――

A full day passed, and all the tiles were firmly in place.

Luo Xun looked around the two rooms with great satisfaction, nodded with satisfaction, pointed to the ceiling, and ordered arrogantly: "Suspended ceiling!" ”

How to hang the roof?

Li Tie and several people gathered around to study the decoration manual, this thing was easily obtained from the building materials city when they collected materials, and it was by relying on it that everyone was able to get the walls of three houses and the floor tiles of two rooms in such a short period of time.

After they tossed and understood the steps of the suspended ceiling, they first experimentally got the roof of the kitchen, and then happily divided the labor and cooperated - Luo Xun and Yan Fei tossed the roof of the bathroom, He Qiankun went to help Zhang Su's house put tiles, and Li Tie divided into two groups to get the roof of room 1601.

Fortunately, Luo Xun and the others took out a lot of each material just in case, and the remaining tiles of the two houses were not enough for the area of Zhang Su's kitchen and bathroom, but there was no problem with pasting his bathroom. In the kitchen? Just deal with the position of the stove, and brush the grout in other places.

Yan Fei didn't leave Luo Xun to get a window for Li Tie and them by himself, first, he didn't want to be busy separately from Luo Xun; Second, it was a long day, and he had no strength to overexert himself yesterday morning, and he had no strength all afternoon, and he had been lying on the sofa all afternoon. Even if you want to help them get the windows today, it's best to wait until the evening to get them, so that you can go to bed directly after you finish them.

Another very important benefit of helping those two houses get windows is the method that Yan Fei has figured out about improving abilities. But although he has a lot of metal in his house, it is always a little boring to use those things to make plasticine every day, so it is better to make something that can actually be used.

Now in this way, you can not only sell your favor to Li Tie and them to build a good neighborhood relationship, but also exercise your own abilities, why not?

Li Tie and the others have work to do to cooperate with the base officials, and they should be able to earn a stable income after that, and as long as they have the opportunity, they will naturally go home to pound metal for Yan Fei. Zhang Su is a bit arrogant and understands the world better, and he is a medical talent urgently needed by the base, so he will naturally have a normal income in the future, and he can also get back the metal. For Yan Fei, he will not lose money in this transaction.

Yan Fei is very shrewd, although Luo Xun doesn't know why he is kind enough to help them get windows, but no one is more careful than Luo Xun when it comes to their own safety. If Li Tie and Zhang Su's house can ensure safety, the safety factor of their own house will also increase significantly.

With the help of the metal ability, Luo Xun didn't have to hammer nails between the planks with his own hands, and Yan Fei could get the intersection of the planks with just a wave of his hand. The roofs of the two rooms, plus the actual yàn at the beginning, and the planning didn't take much time in total, and the roofs of the toilets and bathrooms were all completed in less than half a day, which was even faster than Li Tie and them.

As soon as he finished his work, he heard a sound in the corridor, and the people who were busy came out of the room one after another to see Second Lieutenant Ding standing behind the iron plate of the stairs, knocking on the iron net with his hands in surprise.

After seeing them come out, Second Lieutenant Ding asked in surprise, "You made this thing?!" "Before, it was a big iron plate that blocked these three gates, but today it has become something that is half iron plate and half net? And look at how thick each of these "nets" is? Even if you use a hacksaw drama, I'm afraid it will continue for a while.

Standing behind the iron gate and closest to the stairs, He Qiankun smiled and touched the back of his head, his eyes drifting to Yan Fei unconsciously.

Not only him, but Li Tie and the others who came out behind couldn't help but look in the direction of Yan Fei.

Luo Xun is powerless to support his forehead, these children are kind-hearted people, but they are too straightforward, and they still can't let them know about ordinary things, even if they are important, otherwise others will be able to cheat the truth casually.

Yan Fei didn't really intend to hide his ability after knowing exactly the base's attitude towards the supernatural and confirming that he was not the only metal-based anomaly in the base.

"Metallic Adeptus!" Second Lieutenant Ding was startled at first, and then suddenly he was shocked, no wonder, no wonder they were the only ones here who would use a big iron plate as something to block the door! But it's a very good precaution.

Smiled and took a closer look at Yan Fei, they only thought that there were power-based abilities here, or there were elemental powers, so they were relieved to place Zhang Su's uncertain bomb here. Now it seems that with this metal-based ability, even if Zhang Su occasionally smokes a wind, someone can suppress him, and it shouldn't kill anyone...... Right?

"I'm here today to inform a few of you, tomorrow our base will start building a network, and strive to open an information channel in the base as soon as possible so as to assist in future work. So tomorrow morning at eight o'clock, the five of you will go to the barracks to report first. As he spoke, he handed Li Tie and the others a list with specific notices printed on it. The luck of the five of them is relatively good, and now those senior talents with professional skills have not been completely evacuated to the southwest base, so they will let a few people participate in this job.

After a few days, even if more experienced people come to the base, as long as Li Tie and them get started quickly enough, they will not be laid off. But if you wait a few more days, and wait for those who have been rescued from other bases to be stationed in the base, this job will not be so easy to find.

After the notice was handed over to Li Tie and them, Second Lieutenant Ding looked at Yan Fei again: "Are you a metal-based ability?" Seeing Yan Fei nodded, he hurriedly said, "The base is now in urgent need of personnel to participate in the construction of the wall, you should have also seen the situation outside the inner wall, right?" The outermost part was built by metal-based anomalies. But now the number of metal-based abilities in the base is too small, and the construction of the outer wall is very intense, so the base is looking for metal-based and earth-based abilities to participate in the construction work. ”

Comrade Yan Fei, who was needed, silently broke out a layer of goosebumps, and did not speak immediately.

Fortunately, after seeing Yan Fei's troubled appearance, Second Lieutenant Ding faintly raised his difficult Cheng Dù to the level of Zhang Su - I'm afraid all beautiful men are just as difficult to handle, hard to talk to, and you have to be careful that he suddenly goes crazy at any time, right? So Second Lieutenant Ding immediately continued to persuade: "Don't worry, if you participate in the work, the salary will definitely be much higher than that of ordinary people, and there will be some other benefits, you can also put forward some needs yourself, and we will try to meet them." ”

Luo Xun suddenly asked in a flash of inspiration, "Can you give us some metal besides points?" It is best to use stainless steel or a single metal such as copper with relatively high purity. "They found everything from the outside, but none of the purer monometals.

In addition to being used as utensils, high-purity copper and other things have some other functions, such as conductive copper wires or something? The things they usually go out to collect and find people to exchange for are too miscellaneous, and it is difficult to distinguish them one by one, so it is better to ask the military as a reward!

Second Lieutenant Ding was taken aback for a moment, remembering that Luo Xun was Yan Fei's "cousin" who could speak on his behalf in some aspects, and pondered for a moment: "I can apply to my superiors. "After all, the metal base is also in demand, especially the metal that is being built on a large scale is also in short supply, but it should not be a big problem to separate some single types of metals with higher purity.

Yan Fei suddenly said: "If the metal is really not enough, it doesn't matter, it's okay to have something in the head of a zombie with that speed and strength." ”

"What's in the head of a zombie?" Second Lieutenant Ding was surprised, he hadn't specifically heard of what was inside the head of that kind of zombie, but he knew that the zombies outside seemed to be "evolving" on a large scale, and the evolved zombies became more difficult to deal with. Thinking of the rumors among some soldiers in the army who have read a lot of novels before the end of the world, do you ......, "This one also needs to apply, and I will try my best to fight for you." "He doesn't have the power to decide, but he can raise it up. After all, the points of the base cannot be issued casually, and if there are people who participate in the work and need some less important material rewards, they can still apply upwards.

It's just that most people ask for things like quilts, coal, stoves, and even pots and pans, such as things that are not strictly needed...... It's all weird.

After saying this matter and letting Yan Fei think about it, if he agrees, he will go to the police building at the west intersection early tomorrow morning to look for him, and then Second Lieutenant Ding smiled and pointed to the "door" that he passed by when he just came in: "I said that when I came up today, how could I see that your big iron gate has become a bird cage." ”

"Birdcage ......" the corners of everyone's mouths twitched.

Han Li raised his hand and said, "I used to make a fence, but Brother Luo said that it looked like a prison, so Brother Yan changed it to the ...... now" As a result, everyone's big iron gate evolved from an iron plate to a "prison fence", and then from a prison fence to a "bird cage......

Second Lieutenant Ding didn't stay long, and after confirming that all the residents on this floor were alive and healthy, and that they could participate in the work of the base in the future, plus they had unearthed an additional Flash who could serve the construction of the base, he was elated.

Although he was originally responsible for all kinds of liaison and notification work in this area, he didn't have to come here in person today, but they just came over yesterday to bomb them at irregular times, so they had to come over in person to confirm their safety, right? Fortunately, after coming over, I not only confirmed this, but also discovered Yan Fei's ability by the way, which is really a double surprise~.

Before leaving, Second Lieutenant Ding did not forget to remind everyone: "Don't just strengthen the gate, you have to be careful to close the windows here, especially when you go out to work later, be careful not to let thieves in." Dozens of bases have been broken into these days. Now that the base is understaffed, it is difficult to deal with this matter, so you must be careful and vigilant. ”

In fact, it is not just as simple as breaking through the empty door, there are also many cases of disappearances and murders and corpses in the base, but because the base is too short of manpower and the composition of idle personnel is too complicated, there is no way to deal with it for a while.

Wu Xin's body trembled, and his eyes were a little tangled: "Dozens? "They can understand more than a dozen, but dozens ...... How big is the base now!!

Second Lieutenant Ding smiled bitterly: "The people we left behind strive to patrol a few more times a day, and if there is an accident, even if you shout for help, okay, I'll go first." ”

After Yan Fei restored the door, he looked at Li Tie and the others: "I'll deal with the windows of your room first." "Li Tie and the others are going to work tomorrow, and they have a lot of valuable things at home, of course, they have to give priority. However, Zhang Su's own force value is already high, and he will be recuperating at home for a while recently, and he is not in a hurry for the time being.

After having the experience of the first day, Yan Fei put up the guardrail very quickly today, especially Luo Xun's house is three sides outward, and there is a small second floor, there are three walls and windows to deal with outside, while Li Tie and the others only have windows on the walls in two directions to deal with, and the workload is much simpler than 16031604.

After finishing the window, Yan Fei felt that there was still a lot of mental power to consume, so he simply changed the big iron gate blocked at the elevator and staircase into a gate. And once these doors are opened, they will make a lot of noise, which can remind each family that someone has gone upstairs, which is completely done.

Luo Xun returned to the room with Yan Fei, who was a little out of strength, helped him to the sofa and lay down to help him take off his shoes, and suddenly remembered that Second Lieutenant Ding's construction was a little worried: "Although you make a lot of money by cooperating with the official to build a wall, once you use up your mental power, you will be overdrawn, what if there is danger at that time?" "This is a big problem, the military is naturally protected by the military, but what about it? He is a foreign aid, not that Luo Xun does not trust the military, but if there is any danger involving his own comfort, people will always subconsciously give priority to protecting themselves and those closest to them.

But Yan Fei was not one of their "close" people.

Thinking of this, he hurriedly said, "Otherwise, let's not go!" So much food and drink at home is enough for me to support you! ”

Yan Fei laughed, raised his weak hand and rubbed it on his head, with obvious tenderness in his eyes: "The main reason why I want to go out is that I can consume a lot of abilities every day. Rest assured, I'll carry my crossbow with me, and I won't run out of abilities every time I use them. "Every time I use the clean ability and then recover, I feel extra energetic, although the feeling of overdraft after using the clean mental power is very uncomfortable, but I have to say that the feeling after waking up the next day is too good to be good.

It's like the weird feeling of being beaten up on the first day and completely recovering the next day. Hmm, what's the point of saying that there's always a feeling of m?

Luo Xun grinded his teeth and suddenly his eyes lit up: "You can also go with the two of us." ”

"Huh?"

"I don't want to be paid, but if I encounter danger, I can handle ordinary zombies!" Luo Xun looked at him, his eyes shining brightly, "As long as I bring the big crossbow and spiral bullet you made, I can handle it even if it is an upgraded zombie!" "His crossbow has been honed in the defense of the city. As long as the weapon in his hand is in hand and the lethality is large enough, not to mention ordinary zombies and first-level zombies, even if it is a second-level zombie, he can find a chance to kill it!

It is now the first year after the end of the world, and the zombies have evolved into first-level zombies on a large scale, and as long as they are not surrounded by a sea of zombies, he can ensure that he can escape with Yan Fei in a small encounter.

In fact, this mainly relies on the metal crossbow made by Yan Fei, the crossbow he made is more powerful, and the lethality of the crossbow bullet is also greater, if he can get a special crossbow bullet soaked in a special liquid medicine in the future, it is possible for him to sneak attack the zombies above the third level.

Luo Xun's words were not a joke, and it was very clear how accurate and strict his crossbow was. And just drive to build the perimeter wall...... But in case of danger......

"The house still needs to be dried for a while, and the things grown in the house don't need to be stared at all day, and the base of the ability that the ability can't use for a long time should also be clear, I don't think the work will take longer than the person who built the wall. Even if I go with you, it won't delay our family much. ”

I have to say that Luo Xun's words are very convincing, Yan Fei thought about it for a while and agreed with him, and decided to take him with him tomorrow to see the situation.

After taking a nap on the sofa to replenish the energy they had consumed, they had done most of what they needed to do now in the next room, and now they only had to wait for the house to dry and then brush the putty once or twice, and then paint the walls and dry thoroughly before they needed to lay heat pipes on the floor, and after that, the two needed to continue to be busy, and now just put the house there and not they continued to be busy.

Li Tie and their movements were also very fast, after hanging the roof, several people worked together to help Zhang Su pave the bathroom with the remaining tiles, and also helped him get the sink and stove in the kitchen by the way, so they returned to their room to rest with great satisfaction.

After Yan Fei got up in the afternoon, he felt that his mental strength had recovered a little, and after thinking about it, he decided to go to 1602 and finish Zhang Su's window by the way-God knows if he participated in the construction of the base, would he still have the strength to help him get the window after he went home? This is a matter of safety for the four rooms on the first floor, and the sooner it is settled, the better.
