Ling Yan Thirteen was too impressed by Shen Yan, it was the first alien he had ever seen, even if the other party was a replicant in Mila's mouth. Especially the other party's ability to control the mutant beast, as well as the move of chasing all the way to Xinyang City, made Shen Yan remember it vividly and be on guard at all times.

"This guy is really haunted! After a few months, his ability to control mutants seemed to have grown. Shen Yan looked into the distance and muttered softly, as if he could see Ling Yan Thirteen.

The roar in the distance stopped, and the mutant beast group calmed down, but they no longer struggled as before, but began to slowly accelerate, and within a few minutes, they arrived hundreds of meters outside the moat, and they were only about a kilometer away from the city wall, such a distance The ordinary firepower on the city wall could not be reached at all, obviously intending to avoid the long-range attack of the human side.

"Aang!" The roar that had not been heard for a long time rang out again, but this time it was extremely short, and the sound settled, and the mutant herd suddenly changed. I saw that in the dense herd of mutant beasts, a group of big guys with at least a thousand numbers and a body size of two-thirds of an elephant suddenly appeared.

"Damn, when did the pig become like this, if it is killed, I am afraid it will be enough for hundreds of people to eat several meals!" Looking at the big guys who were slowly gathering together, Guan Feng first stared at him and exclaimed.

Pigs, indeed, those big guys, if you look closely, are indeed similar to the pigs they were before the disaster, the only difference is that they are now very large and have very long manes.

"Quick...... Look, what are they doing, are they ......" Lei Zheng suddenly pointed at the mutant pigs and exclaimed.

Just now, because those pigs were just gathered, Shen Yan didn't know what the other party was going to do, but in Lei Zheng's exclamation, everyone hurriedly looked at it. I saw that those mutant pigs were lined up in a long phalanx like a formation at this moment. When the phalanx was formed, the bodies of those pigs began to expand like balloons, and the manes on their bodies also stood upside down at this moment in the process of expansion, like hedgehogs.

"Quick, hidden, hidden!"

Looking at the posture of those pigs and the upside-down steel needles, Shen Yan hurriedly shouted loudly when his heart moved, reminding the wolf warriors on the surrounding city walls to pay attention.

Shen Yan pulled Cheng Yanqiu beside him, his body was short, and he squatted under the wall, and as soon as he finished his action, a burst of breaking air sounded in the distance.

Guan Feng and the others also saw the abnormality of those mutant pigs, and they squatted under the wall under Shen Yan's reminder, none of them knew what would happen later, but they knew one thing, that is, these mutant pigs would attack from a distance.

"Whoosh! Sou! Whoosh......"

The sound of breaking the air came from far and near, like the sound of arrows and feathers crossing the air. The voice was sharp and harsh, and Shen Yan and the others judged from the rapid galloping sound that these arrow feathers formed by the mane of the pig were no worse than the real arrow feathers, and even stronger.

"Poof! Kiss! Boom ......"

The sound of sharp weapons piercing into the walls soon sounded on the city walls, and at the same time, everyone also felt the sound of a breaking wind flying overhead, falling directly into the city walls. Suddenly, a series of screams rang out under the walls inside the base, as well as shouts from panic.

A few mane arrow feathers landed not far in front of Shen Yan, and the mane was as thick as a little finger, and the length was longer than the palm of the hand. Shen Yan was horrified in his heart, he really didn't expect that the pig on the human chopping board earlier would become so strong now. I just observed that although the other party's body was big, the mane on his body became much thicker and longer with the body shape, and it looked very soft, but I didn't expect it to have such power.

"Artillery battalion, hit those pigs hard for Lao Tzu, damn it!" Guan Feng shouted loudly, being forced by a group of pigs to hide in the corner, this is something that Guan Feng absolutely cannot tolerate!

"Fortunately, the long-range attack of these porcupines is not too far, if it reaches more than two thousand meters, it is really uncomfortable!" Porcupine is the name that Shen Yan temporarily gave to those mutant pigs, and these porcupines at the moment are obviously much stronger than those mutant pigs commanded by the other party when he first met Ling Yan Thirteen. Having the ability to launch long-range attacks is very tricky for humans.

The distance of two thousand meters has an impact on the sniper's shooting, even if the sniper rifle is strong enough to be extremely far, but in the face of the current defense of the mutant beast, the sniper rifle will not achieve the killing effect at such a distance, but there is hope for a thousand meters or so.

"Lei Zheng, the defense of the base is handed over to you, use the sniper rifle array to beat me hard." Shen Yan roared loudly, but the person immediately got up and ran to the entrance next to him after the first wave of the porcupine's attack. As Shen Yan got up and left, Guan Feng and Cheng Yanqiu also followed, while Lei Zheng quickly gave the order to snipe the porcupines in the city wall defense line.

The walls of the first base of Fengcheng were as high and thick as Shen Yan had suggested. Its height has only been completed in the first phase, and it has reached a height of 50 meters, and the second phase of the project will be increased by another 50 meters. The height is only 50 meters, but the thickness is a full 200 meters, and the thickness of these 200 meters is divided into two parts, inside and outside. The outer 50 meters belong to the defensive surface, and every 50 meters inside there will be a fortification with a length of 100 meters and a width of 10 meters, and a platoon will be placed in each fortification. The outer side of the fortification is covered with shooting windows, which are small outside and large inside, which is not only convenient for the wolf warriors in the fortification to attack, but also prevents mutant beasts from entering from here.

On all four sides of the wall, there are three layers of such bunker-like fortifications distributed from more than 30 meters.

The interior facing the base is the kind of residential building that Shen Yan originally proposed, which is integrated with the external fortifications, and is connected by a ten-meter-wide corridor in the middle, which is divided into three floors and just connects the three layers of fortifications, completely connecting the four city walls. But the entire passage is connected to the outside by four huge lifts, and after the lifts land, they have to go through a fifty-meter-long passage to get out, with the four metal gates at the entrance of the passage built on the model of the alloy gate of the second base, even if the city wall is breached from the inside, as long as the gate is closed, it will become very difficult for the enemy inside to get out!

In addition to the four safe passages, the internal residential building area can actually enter the inner fortifications of the city wall, although these entry points have ten places on each wall, and the upper and lower three floors are thirty, but the portals of these entry points are all normal portal size, and they are completely made of steel, and they will be closed in time of war, even if they are really breached, it is very troublesome for the enemy to want to come out of this residential area like a honeycomb inside. And that's not counting the last gateway to the interior of the base.

The residential area inside the city walls is where the base wolf warrior legion is stationed, and a field hospital is also set up on each wall. In short, the entire city wall was not only a blockhouse against foreign enemies, but also a barracks.

Shen Yan, Guan Feng and Cheng Yanqiu quickly came to the ground from the city wall, and the part of the base near the city wall was a bit miserable, because the attack of the porcupine was so sudden that at least hundreds of people were injured on the ground, and dozens of people died on the spot. Shen Yan When they appeared, the medical staff were rescuing the wounded!

"Whew! Shout! Whew......"

Shen Yan had just walked out of the sky, and the sound of a sharp weapon breaking through the air sounded again in the sky, and he hurriedly shouted loudly while dodging: "Be careful, hide quickly!" ”

The sound of "Bo Bo Bo" sounded again, with the first experience, this time as soon as the sound started, the workers outside had begun to look for a place to hide, but in the end, dozens of people were injured and fell to the ground under the attack of porcupines.

"Damn it, these damn brutes!" Long Yu scolded, but he didn't care about it, and hurriedly rushed to the center of the base. It was the former waiting hall of the railway station and is now the headquarters of Base 1.

At the beginning of the construction of the base, Shen Yan considered the situation after being besieged by the enemy. So in order to retreat, the base was built in the early stages of construction with an underground tunnel that led to the perimeter of the base far away. In order to fight, they also built two tunnels that were smaller than the evacuation routes, so as to facilitate the internal and external mobility of the troops.

In four months, not only was the initial construction of the base walls completed, but also several tunnels were completed at the same time. In such a short period of time, it would have been impossible to complete such a large project under normal circumstances before the disaster, but now it is truly unfolding in front of people's eyes.

The reason why it can be achieved is that the number of people is large, and everyone works together is one thing; All kinds of material resources are endless, and abundant supply is another aspect; And the rest of the side is that the second base gets a lot of related technology. This is also why Zhan Tiancheng before felt annoyed because the war came so soon. If there is time, it will not take another four or five months at most, and many of the constructions of the entire base will become more perfect.

"It seems that our defense system is still not perfect, and a certain number of bunkers should be established on the inside of the city walls, and the buildings inside should not only be tall and strong, but also conducive to dodging the enemy's long-range attacks and aerial attacks!" While running wildly, Shen Yan said to Guan Feng.

"Well, that's how it should be, and the underground part needs to be speeded up." Guan Feng interfaced, but then scolded: "This damn virus actually gave a pig the ability to attack from a distance." And that Ling Yan Thirteen, if I was allowed to see him, I would definitely kill him. ”

Soon Shen Yan and the others arrived at the headquarters, where two thousand elite wolf warriors were stationed neatly, and their existence was for special combat missions. In the face of the mutant beast's official attack, it was indeed time for them to set off.

ps: It's still a change today, and there will be time tomorrow a day, and the two changes are guaranteed, and I will try to make up for it!
