Yan Fei was the first to recover, and with a wave of his hand, a row of metal fences would be completely stopped by the big pit that Xiao Xinran had turned into sand, and then beckoned the metal placed on the side and paved it directly to the bottom of the pit.

The entire pit was covered with a layer of non-ferrous metal, even the surrounding "walls", as if there was a "groove" made of metal here. In this way, the entire pit completely fell into Yan Fei's control.

Then, another pile of metal flew into the pit, and a layer of steel thorns was erected at the bottom of the pit.

At the same time, everyone is shooting those high-level zombies among the zombies who are surrounding them one after another, so as not to have other accidents after the zombies fall into the trap for a while.

When the last layer of steel spike traps was completed, Yan Fei took out a metal-sealed box from his bag and glanced at Zhang Su beside him. Zhang Su raised an eyebrow at him, indicating that he could do it at any time. Only then did Yan Fei "float" the box to the top of the pit and open it.

Bright red juice spilled out, and with the help of Zhang Sufeng, it was sprinkled almost everywhere at the bottom of the pit.

"Let's get ready to work." Luo Xun saw that all the preparations had been completed, and the sky was completely dark, and the smile on his face deepened.

"Okay." Yan Fei's voice also had a hint of excitement, this was the first time they had used this method to kill zombies, and today we will see what the effect is.

The fence around the pit instantly fell towards the inside of the pit and suddenly turned into a thin layer of metal plates that spread over the entire pit.

Everyone got up and stepped back, watching the excited zombies rush towards the gap where everyone was just now, densely packed, there was almost no gap between each one, just when these zombies rushed to the gap, suddenly! The steel plate that had just covered the pit "disappeared" in an instant!!

All the zombies above the pit fell down instantly, and what was even more terrifying was that the zombies who followed closely behind also rushed to the pit one after another!

The lowest zombies were immediately punctured by the lowest steel needles, and after being contaminated with the mushroom juice at the bottom, white smoke rose - their lower limbs began to rot!

Everyone gasped, and looked at these zombies who had just fallen into the pit, as well as the zombies who rushed to the pit one after another, and were speechless for a long time.

"Yan Fei, cover the cover." Luo Xun's voice suddenly came from everyone's shock, making everyone suddenly come back to their senses as if they had just woken up from a dream, and immediately began to prepare for the next move.

Yan Fei laid the steel pipes that had been "pumped" away before back above the pit again, but this time it was no longer a steel plate, but an "iron net" intertwined horizontally and vertically.

"Pour gasoline."

The new order was issued, and everyone excitedly picked up the gasoline barrel that had been prepared aside, and splashed it into the pit as evenly as possible with the assistance of Zhang Su's wind system, and then, Xu Mei threw a small fireball into the net - "boom" burst out, and the huge fire was shining, like a fiery red flower blooming in the middle of the night, which was brilliant and dizzy.

"Alright, let's all go back, today's work is almost over." Luo Xun breathed a long sigh of relief, after such a burn tonight, even if there are zombies coming over in the future, they will basically be barbecued on the Internet, and only a very few can break through the defense line. What's more, before the fire was lit just now, Yan Fei used the remaining metal materials to completely seal the previous small door, so as not to spread the fire to the people hiding in the bank.

The fire burned for three hours before it subsided. When everyone woke up the next morning and opened the door, they saw a large pit that had been burned black, and there were no zombies in it anymore.

There are still traces of black smoke occasionally floating out of the big pit, Luo Xun and the others pinched their noses and looked at it for a long time, but they couldn't see any complete limbs, but the zombies who were killed by everyone in various methods yesterday looked relatively complete at this time.

"Pick up the crystal nucleus and see how efficient yesterday was." Luo Xun laughed] turned his head to look at Yan Fei, "It's up to you to pick it up." He pointed to the pit.

Everyone looked at the black pit with a funny face, although they knew what Luo Xun meant, but it felt extremely weird to think about letting Yan Fei deal with this disgusting pit.

Although picking up crystal nuclei or something is not tiring to fight zombies, it is also an annoying repetitive job, and it takes a whole morning of work to basically dispose of the dead zombie corpses, and those zombies who died outside are also piled aside and ready to turn around and burn them uniformly. However, the crystal nucleus in Yan Fei's big pit is easier to deal with. He first manipulated the big metal frame to "fly" out, and turned the bottom layer of metal into a "sieve" in the open space on the side, the mesh of each sieve was smaller than the size of an ordinary crystal nucleus, so he only needed to manipulate the metal box to shake it, and he could shake off the zombie ashes, leaving a relatively intact large limb and crystal nucleus.

Because last night's gasoline was used more, and the zombies that were burned were burned more thoroughly, he was the first to complete this treatment! Not even the hands were dirty.

The mountain-like crystal nuclei were piled up in front of everyone, except for the ones used in the previous battle, they actually got a full 4,000 crystal nuclei in more than half a day yesterday! Four thousand!!

Everyone gasped in unison, and everyone's eyes were shining as they looked at the pile of crystal nuclei, four thousand! That's 3 times more than last time!

Yan Fei thought for a moment: "There are more than 4,000 crystal nuclei here, and everyone has contributed a lot this time, so let's just take 1,000 for each group - or me and Luo Xun, Zhang Su and Wang Duo, Li Tie and Xu Mei." This time, Xiao Ranran contributed a lot, and the remaining fraction was divided among the three ladies, do you have any opinions? ”

Li Tie and the others glanced at each other, and said a little embarrassedly: "A few of us didn't make any effort, the weapons were all made with Brother Yan's help, and Brother Luo, if we didn't have Brother Luo to help us train, we wouldn't be able to hit the zombies, it's too much to take a thousand crystal nuclei......"

"Yes, yes." Han Li and the others also hurriedly nodded. Although they also hope to have a big harvest, they know their own strength better.

Luo Xun smiled and persuaded: "I'm also an ordinary person, and don't forget that there are four of you, it's not easy for everyone to come out and fight zombies once, everyone is fighting for their lives." And even if you can't use it, you can still exchange it for us when you go back? Yan Fei, Zhang Su, and Xu Mei can exchange them for other things, which is better than us going outside to find someone else to buy crystal nuclei. ”

Xu Mei and the others also nodded hurriedly, after all, if there were not enough ten people, they would not be able to get out of the base even if they had great ability. Li Tie really doesn't have much ability in large-scale killing, but they can clean up scattered zombies and take over everyone's defense when the supernatural ones are resting. Without them, these abilities wouldn't even have time to rest and replenish their crystal nuclei.

The second-level crystal nuclei have been distributed to everyone according to everyone's different departments, and to Luo Xun and Yan Fei's surprise, I don't know when they actually hit a few second-level metal crystal nuclei! These zombies don't know how their abilities are going to be manipulated because they don't have metal to use? Otherwise, there are so many metals nearby, and they haven't even attacked everyone?

Of course, there is another possibility - they died under the combined abilities of Zhang Su, Xu Mei, and Yu Xinran, and they were not discovered by everyone in time.

After everyone cleaned up the zombies outside, it was almost noon, and they were about to go back after lunch - the zombies around the outside had basically been cleared, and only some zombies wandering over from the forest were left to ignore at all.

Yan Fei got up and prepared to go outside to turn the trap over - the bottom side up, so as not to trap the vehicles and pedestrians passing by when everyone didn't know it. Before he could walk out of the gate, everyone heard the faint sound of cars coming from the street.

"Passing by again? I'll check it out! Wang Duo ran up to the second floor with the binoculars in his arms to look, and ran back after a while.

"A team of teams, followed by a lot, Brother Luo, do we want to play another round?"

Looking at the excitement in Wang Duo's eyes, and then looking at the excited faces of the rest of the people, Luo Xun thought for a while, and confirmed that there were at most two or three hundred zombies behind the convoy, and then nodded in agreement.

Throwing the last blood bag out and preparing the trap, everyone listened to the roaring of the zombies on the street next door and gradually gathered here, and was thinking about how many zombies could come this time and which way to kill the pit, when they suddenly heard the sound of a car in another direction......

"Holy! What's going on! Wang Duo and Han Li, who went upstairs to check the situation, ran down and pointed in the other direction, "There is a long convoy over there, and there are several buses, which are also coming from the direction of the city, and there is a long line of zombies at the back door, and you can't see the tail of the team at all!" ”

On the way back to the city, intercepting the passing zombies and playing crystal nuclei is certainly a good thing for the benefit of others and self-interest, but the trick is - when everyone is about to leave after fighting the last few zombies, a big wave of passing zombies suddenly comes from behind!!

When everyone was thinking about whether to retreat, the zombies that had passed by before had already gathered, and Luo Xun immediately made a decision - all of them were cleaned up!

A wave of zombies has blocked the gate, and there will be a large number of them in the future, if you want to leave safely, it's best to kill all these zombies first, and talk about other things later. Even if they go back later today, it is better than venturing out now - although they have cars, even if Yan Fei reinforces the cars that everyone is driving with the help of Yan Fei, but the bottom of those cars is also ordinary vehicles, not as powerful as off-road vehicles, and not as strong and crash-resistant as some cars, how can they rush out?

Even the small container car that Luo Xun and the others got can't be used to really hit zombies, but if they encounter two limbs alienated, they just wait to be pulled out of the car by zombies!

The trap was quickly transformed by Yan Fei again, and the zombies in front of them rumbled into the pit one after another, but the zombies who came later also rushed here tirelessly-all the reason for the blood bag that was thrown out at the end!

Luo Xun silently learned a lesson in his heart, and at the same time led everyone to shoot the zombies in the pit - it is inconvenient to directly light the fire in the pit now, because the number of zombies attracted by the cars behind is even more, and they have to wait for them to fall into some of them before they can act.

The convoy where the bus was located seems to be the survivors who originally lived in the city, and they are preparing to flee to the base, although many people immediately fled to the base to avoid the danger outside, but the number of people who are still stranded in the city to make a living is not small. Some families rely on themselves to live in high-rise buildings, and ordinary zombies can't climb up, and once they clean up the zombies in their own buildings, they will use this as a base point to live.

If there is an organization in the community, they will also build fortifications, and usually organize the able-bodied and able-bodied ordinary people to go out to gather food and supplies.

Zhang Su used to live like this outside the base, but I don't know why his previous companions also went to the base, and they were killed by him.

Now, these buses may have been evacuated from the city to the base for the same reason. After discovering that many of the zombies suddenly left the team and ran in the other direction, although I guessed that there were people nearby who were injured and the smell of blood on their bodies led the zombies over, no one in the convoy that had fled to the edge of the city would check the situation. They finally got rid of these zombies, how could they get into trouble for themselves? As for those who are injured and lead to zombies? Let's ask for more blessings.

Most of the zombies who rushed to the direction of the main gate fell into the big pit one by one, but what gave Luo Xun and them a headache was that the number of zombies coming behind was even more than the number of zombies in front! The more zombies that fall into the pit, the more zombies that fall into the pit will be able to climb up with the ones in front of them!!

"At most, nearly a thousand zombies can be killed in the big pit, and if there are more of them, they will crawl out." At the time of the crisis, Luo Xun's mind calmed down, and he immediately turned to He Qiankun beside him and said, "You and Li Tie went over to check to see how much gasoline was still available?" "The last part of the more than 4,000 heads yesterday fell into the trap and burned to death, and the rest were killed directly by Zhang Su and them with their abilities! How can there be so much in the big pit?!

Hearing this, the two hurriedly ran back, Zhang Su and the others were uniting to kill the zombies who had fallen into the pit and were struggling, and the second-level zombies who were running here a little farther away and might hurt everyone.

Li Tie and the others ran back not long after: "Luo Xun! A third was used before, and there are still two-thirds left! ”

Luo Xun nodded: "Leave two buckets and don't move, and move the rest." As he spoke, he looked at Zhang Su again, "After a while, you will assist them to get gasoline into the pit together, and ...... the same as before."

Not necessarily a word, suddenly Xu Mei beside her exclaimed, and when Luo Xun turned his head to look at her, he saw that the red brilliance entrenched on her had just dissipated.

"Level 2?!" Seeing the escalation of the metal-based abilities made Luo Xun and Yan Fei react immediately.

"Level 2?! Sister Xu, has you really reached level 2?! Song Lingling, who was using water arrows to make trouble for the zombies outside, looked at her with surprise when she heard this.

Xu Mei nodded stunnedly, and it took a long time to make a sound: "Yes, level two!" It seems that the mental power has been completely replenished all at once! Saying that, she looked down at her hand, there were still a few crystal nuclei there, most of which were first-level, and explained with some annoyance, "I was in a hurry to absorb the crystal nuclei to replenish my energy just now, and I accidentally grabbed the second-level ......ones together."

After the completion of her last mission, she didn't use the second-level crystal nucleus to try to absorb it, but at that time, she couldn't absorb the high-level crystal nucleus, so she kept it alone and carefully, and now this crystal nucleus is just divided by everyone, and the first-level and second-level ones are mixed together, and she absorbed one without seeing it clearly.

"How many first-order crystal nuclei did you use when you reached level two?" Yan Fei suddenly asked.

Xu Mei thought for a while: "Maybe...... Four or five hundred, right? ”

Yan Fei nodded: "I'm afraid that so many are needed when the first level is promoted to the second level." As he spoke, he looked at Song Lingling, "Your ability should also be improved as much as possible, I think that even if your ability cannot change its form after it reaches level 2, it may be able to have a more effective way of operating to assist in attacks." ”

Song Lingling just nodded, and before she could speak, Zhang Su on the side frowned and asked, "Why is it useless even if I absorb my second-level crystal nucleus?" ”

Yan Fei glanced at him with a smile in his eyes: "I'm afraid you're in the same situation as me - the mutation ability of ordinary abilities." Therefore, the number of crystal nuclei required is more than that of a normal Tier 1 ability. Although I haven't counted it specifically, it seems that it will cost Xu Mei and the others twice as much as the crystal nucleus needed to upgrade when I reach level two. ”

“…… Thousand. Zhang Su turned around silently, raised his hand, and a gust of wind rolled up the sand that the little girl had made before began to sweep the zombies that rushed over. The number of crystal nuclei in his hand before was not enough, so naturally he couldn't improve his ability, but now although it is enough, it can be a thousand...... Anyway, it's impossible to absorb enough today!

The gasoline was resisted by Li Tie and several people, and the lid was opened. Zhang Su "sent" the gasoline and spilled it into the pit. After the fire ability is upgraded, the lethality is greatly increased, and Xu Mei, who can make more fireballs and make fire nets and fire dragons, is excited, seeing Luo Xun nodding and signaling her to light the fire, she hurriedly waved her hand - a small fireball fell into the pit and lit a grand bonfire!

The flames burned fiercely, but because there was still an endless stream of zombies rushing behind them, everyone couldn't turn around and go back to rest like they did last night.

Luo Xun and the others changed into ordinary crossbows and arrows and began to shoot the zombies who were stagnant outside the pit, Xu Mei used the fire in the pit to manipulate the flames to burn to the zombies next to the pit!

"It's much more mental power saved than firing flames yourself!" Xu Mei exclaimed, she was manipulating the flames on the edge of the wall of fire through the big pit, and a huge fire light separated from the fire and turned into a fire dragon, rushing towards the place where a group of zombies gathered! This dragon is bigger than the dragon she made in her second-tier ability!

Luo Xun looked at the surrounding situation and said to Song Lingling on the side: "You go over there with Xinran, cool down the surroundings with water, and let her sand the land over there, Zhang Su and Xu Mei, wait for a while to make sand and attack with her!" ”

"Good!" The two of them answered, approaching Yu Xinran's location.

Zhang Su also used the wind to make the flames in the pit burn more violently, and from time to time blew out streams of flames to burn the zombies on the opposite side.

Everyone's faces were roasted red by the fire not far away, but fortunately, there was a chapter, they didn't have to worry about the oxygen nearby being burned by the fire, otherwise who would dare to put such a big fire at such a distance?

The sand and metal steel needles were burned red by the fire, and they stabbed into the bodies of nearby zombies under the push of the wind, shooting them head to head......

The fighting continued until late in the evening, when the fire gradually stopped, and the streets outside were densely packed with zombie corpses.

Although they were very tired, everyone who was going back to work at the base tomorrow was all in good spirits at this time, opening the door to clean up the corpses of the zombies.

It took until ten o'clock in the evening for the zombies to be cleaned up. This round of hard work allowed them to obtain more than 2,600 crystal nuclei.

Everyone roughly divided into four parts again, one for each team, took their respective crystal nuclei and cleaned up the zombies near the bank, covered the ground with a metal cover, and the sand that happily melted out was blown flat on top of the metal cover by Zhang Su, Song Lingling sprinkled a "drizzle", and Li Tie stepped on the wet sand to make the soil firm. In the end, Zhang Su manipulated the wind to blow a layer of floating sand to make the color of the ground here as similar to other places as possible, and then everyone climbed into their respective cars - ready to go back to the base.

"Next time, we must not come out until the last two days." Luo Xun yawned, "Let Li Tie and them have a day off a day in advance, so as not to have this kind of accident again." ”

Yan Fei drove the car and said with a smile: "I know, they are going to grind with their heads after they go back this time, to see if they can cheat out one more day of rest." ”

Among the group, only Zhang Su will have a good rest for a whole day after the battle because he has rested for these two days and he can only rest tomorrow morning...... Ah, forget about the three ladies of Xu Mei, the three of them have a very free time, and they can rest all day at home tomorrow.

Not long after the convoy drove out, it turned around and drove towards a nearby commercial street, and Luo Xun, who came back to his senses, suddenly remembered that they hadn't gone to pick up the refrigerator and freezer yet!!

There are still poisonous mushrooms waiting to be collected at home, and there is no place to store them, and if you don't take the refrigerator and freezer back, it will be a catastrophe! When a few people got out of the car to move the refrigerator and freezer, Luo Xun took Xiao Xinran to a big tree on the side of the road, and asked the little girl to melt all the land near the big tree.
