ps: second update

Not long after the battle on Shen Yan's side was launched, Guan Feng's side also launched an attack, 1,500 elite werewolves with a sniper rifle distributed on more than a dozen buildings, and the moment the gunfire rang out, they shot down a piece of the porcupine that was attacking the eastern city wall from a distance, and the surrounding beasts roared again and again, and there was chaos.

To the east is the gathering area of mutant beasts, and the chaos here is much greater than that of Shen Yan, especially Guan Feng and they threw out a few grenades from time to time, and the violent explosion sound continued to expand this chaos.

"Roar!" The roar that dominated the entire herd sounded at the same time as the beasts were in chaos, and I don't know if it was because there were too many beasts, or for other reasons, the chaos of the beasts under this roar did not stop as quickly as it did at the beginning.

"It turns out that this guy has a limit to controlling the herd, and such a huge herd of beasts is really messed up, and it is not so easy for him to control it." Facing the chaotic beast herd on the ground, Guan Feng had a smile on his face, and directly threw a few grenades into the mutant beast herd.

The roar of the dominant beast herd sounded three times in succession, and the chaos of the entire beast herd gradually stopped, but under Guan Feng's continuous shooting and bombardment, those mutant beasts only temporarily subsided. The other party seemed to know that this would not work, and at the moment when the beast herd subsided slightly, three hurried roars rang out, and under the control of these three roars, the mutant beast herd finally began to stop converging, but directly charged towards the eastern city wall. There were even many mutant beasts in the herd that rushed into several buildings, obviously trying to find Guan Feng and launch an attack.

"Hehe, it is indeed troublesome to effectively control more than 300,000 mutant beasts, but you are so eager to charge......" Facing the changes in the mutant beast group, the corners of Guan Feng's mouth turned up and a sneer appeared.

The combat effectiveness of the two thousand elite wolf warriors is indeed strong, but they are never the main force, and it is the wolf warrior legion stationed in the city walls that can really play a role in the recreation of the mutant beast group. However, the mutant beast herd did not attack the city wall directly, but hid far away and continued to attack from a distance, which made the wolf warriors stationed in the city wall become spectators, which was useless at all. Therefore, Guan Feng's strategy is to cause chaos among the mutant beasts, on the one hand, let their beasts attack the city wall; On the other hand, it is also to test that Ling Yan Thirteen, how much control is there over such a huge group of mutant beasts?

Nearly 20,000 mutant birds have been hovering in the air more than 3,000 meters east of the sky since they gathered, and on the ground below them, at least 100,000 mutant beasts have gathered around, surrounding the buildings in this area, and even the top of those buildings has traces of mutant beasts. In the center of these mutant beasts was a building, and on the top of it stood a figure in a black robe. If Shen Yan was here at the moment, he would recognize that this black-robed figure was none other than Ling Yan Thirteen.

At this moment, Ling Yan Thirteen did not have a black robe to cover his head, and his entire head was exposed, at first glance, he looked the same as a human, but when he saw his blood-colored eyes, he knew that he was not a human.

He ...... The strength of the ...... It's stronger......" A hoarse voice slowly came out of Ling Yan Thirteen's mouth: "This battle...... Fail...... You must report to the Lord, not in the ...... Let it go. ”

Ling Yan Thirteen seemed to realize that his move of letting the mutant beast group launch a strong attack just now would cause his own failure, and after the jerky whisper, he let out several long howls one after another, and the whistling sounded, and the mutant beasts on the ground who had already begun to charge towards the city wall became even more violent. Facing the hundred-meter-wide moat, they didn't bother at all and plunged down, and in the blink of an eye, the fifty-meter-deep moat was filled with mutant beasts, and the vanguard team rushed to the other side of the moat, and rushed under the city wall in the blink of an eye.

"Boom!" With a muffled sound, a mutant cow slammed into the city wall like a tank. The majestic city wall did not move, but the mutant cow quickly launched a second impact as if it was not going to die. In the process of its impact, more mutant cows followed, more mutant pigs followed, in short, after the huge mutant beasts came under the city wall, they all began to hit the city wall frantically.

The impact of one mutant ox on the city wall was towering, and the same was true for ten mutant oxen against the wall, but when the number became thousands, the entire city wall finally began to tremble. But the two-hundred-meter-thick city wall was still strong on the ground under the impact of these mutant beasts, and there was no sign of collapse.

The Mutant Beast's attack was not blind, and the large Mutant Beast that hit the city wall was not seeking death. Although the impact after impact made their bodies bleed, the masonry walls began to shatter under their impact. What's more, the smaller, agile mutant beasts have begun to scatter along the walls.

The speed of the mutant beast's charge was very fast, so fast that the defending wolf in the city wall could only pull the trigger and shoot towards the dense area of the mutant beast group. In less than ten minutes, the mutant beasts were killed and injured, but the position on the city wall that they were constantly hitting was finally knocked out of several large holes about half a meter deep.

The dense mutant beasts crowded forward and back, moving forward bravely with a momentum that would not stop without knocking down the city wall. 200,000, 300,000, such a number is just an estimate of the number of mutant beasts on the human side. But when the mutant beast herd launched a strong attack and fully deployed their team, people realized that no matter what they had guessed before, this number would probably have to be multiplied by two, at least two.

There were too many mutant beasts, and when they looked down from the city walls, the entire area within the reach of the land was completely covered by them, and their charge could no longer be described as a wild run, but because of the number, it became a wriggling, extremely fast wriggling.

The corpses were constantly piling up under the attack of the wolf warriors stationed on the city wall, one meter ...... Two meters ...... Five meters, in less than half an hour, more than three thousand meters long under the east city wall, there are more than ten sections of the corpse mountain more than ten meters high, and at this time, there are more mutant beasts in the rear are constantly coming, their actions at the moment, as if they want to pile up a ladder of corpses under the city wall.

"Damn, where is the number of only two or three hundred thousand, five or six hundred thousand I'm afraid it will be exceeded! If we continue to build like this, I am afraid that it will not take an hour to reach the firing port on the bottom floor. "Because of Guan Feng's large number of shots, the number of porcupines has decreased dramatically, coupled with the general attack launched by the mutant beast herd, and those long-range attacks under fast movement cannot exert their power at all, so at this moment, Lei Zheng on the top of the city wall has come here again.

In the face of the huge number of transformation beasts, the naked eye can indeed only see approximately, especially the many buildings left behind outside the city wall for defense, which even blocked the view, making Shen Yan and them only have a rough estimate before. But when the mutant beasts launched a general attack, Lei Zheng realized how outrageous their previous estimate was.

"The corpses of the mutant beasts are piled up to twenty meters, immediately drop grenades, blow up those corpses for me, and extend the firing position fifty meters back." Lei Zheng quickly gave the order, and at the same time relayed the situation here to Shen Yan and Guan Feng respectively.

"No wonder this guy only attacked from the east, it looks like he was going to use the corpse of the mutant beast to climb over the city wall!" Shen Yan received Lei Zheng's notice, and he was also surprised in his heart: "Originally, when I saw so many beasts gathered around, I felt that Ling Yan Thirteen's beast control ability had become stronger, but I didn't expect it to become so strong in just a few months?" Luckily, their ranged attacks are backward, and if there is a long-range attack similar to that of a cannon, then our defenses will really have problems. After this battle is over, the second phase of construction of the city wall must not only be started immediately, but also an additional layer of iron wall will be added to the city wall according to Zhan Tiancheng's previous proposal. ”

There is not much knowledge of the appearance civilization obtained from the second base, but there are several practical knowledge, that is, the refining technology of the alloy found in the warehouse, as well as the manufacturing technology such as biorobots and the manufacturing technology of transport ships. In addition, there are some other technologies, although these techniques are not yet fully mastered, but the initial application is sufficient.

"Captain!"

Shen Yan knew that if they continued like this, no matter how fast they killed, they would definitely not be able to finish killing in the face of such a huge number of mutant beasts. There is no way, the number of the two sides is too different, especially in terms of ammunition, don't look at the storage of ammunition in the base now, but those mutant beasts are either outrageously strong in physical defense after mutation, or they are very fast, and it is impossible to kill them with one bullet, so I am afraid that the mutant beasts have not been eliminated yet, and the ammunition has been consumed!

"What's the matter?" Guan Feng's inquiry came from the communicator.

"Immediately launch a fire attack, the number of mutant beasts is too much, we must block it, and buy time for the city wall." Shen Yan hurriedly said.

"Understood!" Guan Feng hung up the communication after responding.

At the same time, Shen Yan immediately contacted Lei Zheng's side, "Lei Zheng, I don't care what method you use to drag the mutant beasts, at least for an hour, you can't let their corpses pile up over the city wall and rush into the base. Also, at the right time, you can open the gate and actively divert the mutant beasts under the city walls into the base. Made, someone brings us meat, don't be in vain. ”

Hearing Shen Yan's order, Lei Zhenggang wanted to question it, but then gave up this idea, because under Shen Yan's reminder, he suddenly reacted to the emergency measures in the city gate when the base was rebuilt.
