The group went downstairs and got into the car, and crowded into the car to the gate of the barracks. Today's barracks gate looks much more deserted than before the Spring Festival, although there are still people and vehicles coming and going, but there are not so many idle people and other people who can be seen at a glance.

Luo Xun and the others locked the car before entering the barracks, and Li Tie and the others had already entered in advance. After entering the small square at the gate of the barracks, the two found the military truck they usually occupy, and when they passed, they saw that the captain had already arrived.

After seeing Luo Xun and the two, the captain greeted the two and said, "They shipped all the materials yesterday afternoon, and everyone is going to be busy again today." As he spoke, let everyone get into the car first.

After climbing into the carriage, the captain took out three heavy bags and distributed them to the three metal powers, and said with a slightly heavy expression: "Some of us in the team already know, but I still want to explain the situation to the comrades who don't know the situation in the past few days." These words were obviously to be explained to Luo Xun and the others, and the other soldiers did not have any dissatisfaction or opinions, and still listened carefully with straight faces.

"Chinese New Year's Eve the number of zombies outside the base skyrocketed that night, which brought a great threat to the several monitoring points and guard towers established by our base outside...... All sacrificed. The captain's voice was a little heavy, and no one in the carriage made a sound except his.

Luo Xun looked at Yan Fei, and the two of them remembered the sound of firecrackers on the night of the thirtyth at the same time.

"Since yesterday, the base has asked the earth adepts to continue to raise and thicken the perimeter wall, and build a staircase to the top of the wall, striving to build our wall into a large wall that can be patrolled by soldiers like the ancient bunker. Yesterday afternoon, the team that went out to look for supplies brought a large number of metal materials, and we had to go up the inner wall of the wall to continue the construction of the outer metal wall through those stairs and other things. The captain briefly introduced the situation, saying that this mission is more difficult than the previous one, because-"There are a lot of zombies around this time, and now they are all blocked outside the wall, and there is a steady stream of zombies coming in the direction of the base one after another, we can't go out of the city to build the wall, we can only climb up from the inside and find a way to deal with the wall outside." ”

Although the base has thought of some methods and ideas, the specific operation will not be decided until the metal ability arrives. Otherwise, although the zombies can't climb the three-meter-high metal wall now, what if they really evolve like the slow, stiff zombies at the beginning to these zombies with flexible movements, faster speed, and greater strength, and become able to jump in with a single leap? Therefore, the wall must continue to be built in Gaoli.

After everyone arrived at the designated location, they got out of the car and saw that the wall not far away was indeed twice as high as before! Now the earthen wall inside the outer wall is six meters high! It also seems to have widened a lot, and a staircase has been built at intervals.

I don't know if these things are all made by the earth-based powerhouses working overtime? Or is there also the participation of ordinary people?

The area where Luo Xun and the others parked was on the inside of the newly built outer wall base gate, and there were many various metal materials stacked inside the wall.

It seems that the military has brought all the materials from a nearby steel yard.

After taking a look at the stacks of metal materials, the group slowly walked up the newly repaired wall and looked outside, only to see zombies with teeth and claws, waving their black, withered, terrifying arms with long nails in the direction of the clearly audible smell of human flesh above the wall.

"It's a long way off...... Can the ability be reached? Glancing down, the group ignored the zombies waving their arms like the terrifying demons of hell wailing and trying to pull people into hell, a metal ability asked with a headache as he looked at the distant metal wall.

Today, the earthen fence is twice as tall as the metal fence, about six meters, and if you want to "glue" the metal to those places little by little...... How are they going to go down? And I thought that the three-meter wall was already very high, but now look at the location of the zombies below and the top edge of those metal walls...... They should be able to get there in a leap from this distance!!

This is not like the previous time when everyone was standing on the edge of the fence and there were people outside to protect the fence, but now the metal fence is only a short ten centimeters where everyone can stand! I can only barely step on it, and if one center of gravity is unstable, it will fall!

The captain didn't expect the current situation to be so dangerous, and what was even more troublesome was that the number of zombies below was far greater than the number they had predicted before. If they were to build a wall, how would they protect these Adepts? It's no wonder that the earth-based abilities were busy for a full day and a night yesterday working overtime to build the wall, and the base is probably worried that those zombies will jump in from the three-meter-high wall, right? But you won't slowly cultivate meter by meter, so that we can also have a distance that we can reach!

"I'll go find someone to negotiate." The captain thought about it for a while, the current situation is difficult for metal powerhouses to operate, and these powerhouses, including earth-based powerhouses, can only use their abilities to create walls by touching matter with their hands, unlike those fire, water, and wind powerhouses, but they can't throw out a lump of dirt and metal knots with a wave of their hands!

Seeing that there were living people on this wall, the zombies directly below waved their arms excitedly, screaming at the top and all gathered around. Luo Xun and the others stood on the wall, looking at the dark zombies below, their heads were headaches, although this number was far from hitting the point of the zombie siege, but if it continued to gather slowly like this, sooner or later it would form that terrifying scale!

It's just that these few days are in the New Year, and the outer wall has just been repaired, and many people are reluctant to go out to hunt zombies to find supplies for a while.

Luo Xun suddenly looked up at the north side of the new gate, which was facing a large road that had existed before the end of the world, and there was a somewhat strange small building on the left and right of the intersection not far ahead. The building is very high, but the cross-sectional area is only a little bit not too large, some like the simple arrow tower that appeared in the costume movie.

Of course, the role of this thing is somewhat similar to that of the arrow tower, they are the warning building that the captain said just now, which is a small building that is used to foresee in advance and warn against special situations in the periphery.

But at this time, the road outside was full of zombies swaying around, and there were many zombies around the guard downstairs, and they were tirelessly patting the walls of the small buildings, above the roofs of those buildings - someone was there!

It's a little far away, and Luo Xun can't see the situation on it clearly, but there must be someone on it. It's just that they're probably just soldiers who are stuck there and can't be withdrawn for a while.

At this time, some soldiers had gathered behind the gate of the wall, and they should have come out of the wall to rescue those people.

It didn't take long for the captain to hurriedly run back, and said to everyone with a slight breath: "It has been negotiated, the base will open the gate in a while, rescue the people who have been trapped outside for the past two days, and once the gate is opened, it will definitely attract the attention of some zombies. ”

As he spoke, he asked everyone to transport the metal materials to the city wall one by one to save time for a while.

Luo Xun's face is a little unpleasant, in this case, the ability with only one rope on his body will be the most dangerous! It would be okay if there was no other way at all, but there is no way to avoid this danger right now.

Thinking about it, Luo Xun glanced under the wall, but there were no less than fifty or sixty zombies blocked directly below everyone's position, even if some of them would be attracted after the city gate was opened for a while, but it was definitely only a few. If a few of them were not led away and launched a frantic attack on the paranormal who were being hung down by the rope, how could the people who were standing above the city walls and helping to protect them react in a hurry? And what if something goes wrong with those ropes?

Thinking about it, Luo Xun suddenly turned around and walked to the captain's side to give his opinion: "Captain, it's too dangerous to only let the strangers hang under the rope. ”

After hearing Luo Xun's words, the captain saw that he certainly understood that he was worried about the safety of his "brother", but now there is really no other way for the time being: "I just reported this matter to my superiors, but there is really no other way at present, but I can only use the opportunity of opening the city gate to repair as much as I can." Today, the army will send people out to try to clean up the zombies nearby, and it is estimated that it will not take long for our actions to be much easier. ”

Of course, Luo Xun knew that the base would send people out to clean up the zombies, but the problem was that the zombies were converging here, and now the area wrapped by the outer wall was too large and stretched too long, and there was no way to kill all the zombies in all directions and not outside the city wall.

Of course, if the survivors in the base are vigorously mobilized to go out to fight zombies, they may be able to clear all the zombies outside the wall in just one day. But that's not realistic at the moment.

"There's another way to do it safer than hanging the three of them with a rope."

The captain was stunned for a moment, and hurriedly asked, "What way?!" ”

"Cooperate with Earth-based Abilities."

Luo Xun's construction is very simple, but it is just a little troublesome, and his suggestion is to let the earth-based abilities make a "hole" from the inside of the wall at the designated location, and let the metal-based abilities build the outer metal wall from those gaps.

But this requires the assistance of the earth powerhouse, and it has also changed from the original division of labor of three people to the cooperation of three groups of people, and it is more troublesome to tear down the walls that have been built little by little.

Although this is a more practical way to ensure the safety of the metal powers, the problem is whether the manpower can be dispatched, and it is inconvenient to find people to cooperate.

The captain thought about it for a while, and decided to apply to the leader out of the mentality of protecting his teammates. Sadly, ten minutes later, the captain came back in disgrace - he was scolded.

"We were asked by our superiors to act as planned." As he spoke, he sighed and looked at Luo Xun with a hint of melancholy in his eyes, "The number of earth-based supernatural beings is also insufficient, and the number of crystal nuclei is ...... Not much. ”

This part of the earthen wall has already been built, and if it is dismantled little by little according to Luo Xun's words, the outer metal wall is repaired and then sealed from the inside, it will be a repetitive labor.

The higher-ups disagreed, as the number of earth-based adepts was not large enough to be so extravagantly assigned. Moreover, the number of crystal nuclei in the base is limited, and they have deliberately given more to the metal powerhouses to support their work, but now they have so many crystal nuclei and do nothing, and they are looking for excuses to ask others to cooperate with them...... Although you metal powerhouses are indeed very rare, you can't waste resources like this, right?

So the captain was scolded back.

The wall team of the earth and metal abilities belong to different teams, and they also have to compete for the speed of construction to complete the task as soon as possible, who cares if the distance outside you is enough? Can you climb down and fix the metal shell? And even if there is no metal shell, the defense of the earthen fence is not bad, so it would be better to repair it thicker? Is it necessary to be so crooked and always find excuses and reasons to find trouble?

The squad leader doesn't have to negotiate with the person in charge of the earth-based ability, and he can guess what the other party will say to prevaricate himself. What's more, even his superiors don't agree with this construction.

Yan Fei had been discussing the specific operation with the other two metal-based abilities for a while, and after coming over, he heard the conversation between Luo Xun and the team leader and understood that he was worried about himself, smiled, and said to the captain: "I have a way, I can build the wall from the inside without the help of the earth-based ability, and I don't have to go down in person." ”

"Oh?! What a way! The captain hurriedly cheered up and looked at Yan Fei with some excitement.

"Ability Conduction."

Yan Feigang had already communicated with the two metal-based abilities, and had learned that they hadn't really activated the ability to make metal float, though he didn't know that this was the unique effect of his own ability? Or do you have to wait until your metal-based ability reaches high level to naturally have this levitation effect? But you can't just rely on yourself to "float" on it to build a fence, so that these two people are only responsible for carrying and other sundries, right?

Not to mention whether this would be more eye-catching, so that people would sneak into the real room to dissect it when they turned around, Yan Fei had a better way to let the three of them "remotely operate" the metal, and use the effect of guò conduction to make the outer wall.

This is a special method of operation that he discovered when he used the reinforcement of things such as doors and windows in his home, and when he used the steel bars in the concrete in the walls.

Based on his personal experience, there is always a general range when manipulating metal in the air, which is somewhat similar to ranged abilities such as fire, such as the fire wall of fire, and the range within which the wind ability can control the storm around him, and Yan Fei also has such an operating range.

When he was at home, he could roughly determine that this range had a distance of about ten meters with his diameter, which was similar to the operational range of Zhang Su. Of course, the range of the metal arrows and other things he made was not controlled by this, and it was completely judged by the strength of the spiritual power attached to it at the moment he "launched" a long-range attack.

And this effective range of operation is not limited by another operation, that is, "conduction". Using a piece of metal as a medium, attaching spiritual power to it can change the metal shape, appearance, and other things at the other end.

This can be done not only by himself, but also by the two metal adepts.

Although he couldn't understand it, it seemed to be very powerful—this was the unanimous thought in the hearts of all the soldiers who heard Yan Fei's explanation.

The captain was also very confused, after all, he was not an anomaly, and he really couldn't understand the situation intuitively, so he chose the simplest and most direct way to verify - "Can you two do it?" ”

The two metal-based powerhouses nodded excitedly: "We tested it, although it will definitely be difficult if the distance is too far, but it can definitely be done within three meters!" It's just that it consumes some mental energy more than usual. ”

The captain waved his hand: "Don't worry about the crystal nucleus, we will find a way to call you back!" How much to use! Safety first! "This is his own soldier, and if it weren't for the last resort, he would never want to sacrifice any of them! Even if it was an order from his superiors, even if the construction of the wall was slower than that of the afternoon group, he would rather choose a more secure method.

Yan Fei's idea is actually very simple, that is, to use a metal as a "pen", the metal door at hand as "ink", and use the method of a three-D graffiti pen to build what they want.

And is there anything easier than making a big iron wall that is dull and rigid? As long as the effect they make is as hard and smooth as the metal wall that they usually "pinch" with their hands!

The two of them followed Yan Fei's example, made a long thin iron rod out of metal, and then grabbed a piece of metal around them and fused it with the iron rod, and at the same time as fusing the top and bottom, they could gradually merge with the metal wall below, thickening and enlargement.

Although the concentration of mental power is more demanding, the two of them unexpectedly found that their mental power has become clearer and more concise after each replenishment, and the operation is more handy - every inch of the metal they can perceive seems to be "seen" clearly, and they will change according to their own ideas, which is more wonderful and free than when they simply "pinched" it with their hands before!

Seeing that it didn't take long for the three of them to get to work, and that they didn't need to risk hanging ropes at all, they just had to lie on the earthen wall and "draw" it with metal to build the outer wall, and everyone breathed a sigh of relief.

While Yan Fei was resting, the captain said with a smile full of satisfaction: "How did you come up with this method?" Not only was this strange to him, but also the other team members and the two strangers. Although they are all metal-based abilities, they have not thought of changing their form with their minds without using guò media or hands.

Yan Fei sighed in his heart, he had never used it since he just found out that he had a metal ability, and he was all using pure spiritual power to manipulate metal changes, okay? On the contrary, it was the first time I saw other metal-based abilities making things like mud.

But he didn't want to expose this matter for the time being, so he made an excuse at random: "When I put iron bars on the windows of my house, I was afraid that they would not be strong enough, so I subconsciously put them into the wall and connected them to the concrete reinforcement in the wall." Later, I was afraid that the walls would be too heavy to eat, so I tried to reinforce the steel bars again, but I didn't expect to be able to slowly reinforce all the metal at hand into the steel bars in the building, and then I realized that I could still operate the ability in this way. ”

Everyone suddenly realized that the captain smiled: "No wonder you said you want some metal back?" Don't you want to reinforce the walls in your home, do you? ”

Yan Fei nodded with a smile, and glanced at Luo Xun from the corner of his eye: "If there is wealth." ”

"Don't worry, I'll bring you some back when I go back today! They'll go out and pull the steel back in a few days, but be careful when you take it away so that no one can see it. ”

"That's fine, we have a car, just stop where we parked when our truck goes back later." Yan Fei nodded happily.

There are a lot of things at home, and since I heard Luo Xun say that there are two exaggerated large water jugs on the roof of their building, I am always worried about whether the building can hold up these messy sundries - they live on the sixteenth floor! In case it affects the building...... Hehe.

Luo Xun was at a loss as to why Yan Fei always looked at himself, and he didn't expect that he was worried about whether the roof of his house would be crushed by the two exaggerated large water tanks he got before the end of the world, but if he could get something back to Shenma, nothing was more important than this!

Yan Fei's three-person wall operation was carried out smoothly again, and after the captain saw that the three of them were moving smoothly, he called the three people who were responsible for protecting the supernatural and the people who were going to carry things for them, except for Luo Xun, and took the rest of the team members to some places next to them to start - fighting zombies.

Now the gate of the base has been opened, not far away is the team that rushed out in an armored car to rescue the soldiers trapped in the nearby watch tower, and the zombies under the wall were indeed led away, but the human flesh on this wall is really sweet and delicious, and there are at least forty or fifty zombies left who refuse to leave.

The captain's target is these dozens of zombies, and only after completely destroying them can everyone build a wall. Otherwise, even if the paranormal and other soldiers who were busy on the wall were tied with ropes to prevent them from falling, it would not be completely reassuring - what if anyone did fall? Getting caught-clawed is no fun!

After each killing, the other soldiers find a way to hang a dead zombie with a rope with a hook, pull it into the air to dig the head, and take the crystal nucleus. The speed and efficiency, while a little slower, are much better than nothing at all.

Luo Xun was carrying metal materials for Yan Fei on the side, and he was always alert to the zombie situation below, and from time to time he would shoot a few with a crossbow.

Although Yan Fei's operation requires a lot of crystal nuclei and mental power, the effect is really good, and its consumption efficiency is already comparable to the efficiency of him making a large lump of metal lumps into a metal mesh every night before going to bed - although it is still not as strong as that.
