The flock of man-eating birds began to agitate, they circled faster, and finally, almost at the same time, they not only attacked the repeater from different directions, but also split into several of them, some swept under the repeater, and some directly tried to attack the strong magnetic base of the repeater, in a vain attempt to counteract the invisible attack with numbers, but without exception, they all seemed to suddenly lose their ability to fly, and fell from the sky one after another.

The man-eaters who fell to the ground were almost all incapacitated, only a few of the outer edges were still fluttering on the ground, and the inverter gunners at the outpost were using the inverter guns to replenish their guns, but they found that the inverter guns were not very useful, and they didn't know if it was due to the power or the speed that could only select the frequency, and it would take about one to three seconds to completely incapacitate the man-eating birds, but it was enough to deal with these half-dead guys.

Jin Junmei saw this scene on the screen in the command cabin, she was hot-blooded, and she couldn't wait to go out now and kill a few man-eating birds herself, but because Ah Jun didn't give the order, she really didn't dare to act without permission, but her heart was really uncomfortable.

As the man-eating birds fell to the ground one after another, for a while, the sky above the camp was much clearer, and only one person in charge of relay communication was still hovering in a safe area.

Ah Jun knew that this was not the end, but the beginning of another attack, so he asked Cheng Gang to restrain all the personnel and continue to stay at his post.

Sure enough, in less than twenty minutes, another group of man-eating birds gathered, more than last time, they still circled around the repeater as usual, and then a man-eating bird first rushed towards the repeater, and then detonated the high-energy battery in the body before it was attacked by the frequency attack, the huge shock wave made the repeater swing out instantly, almost out of the support of the strong magnetism, but the repeater has two buoyancy to rely on as a guarantee, the main buoyancy is an ultra-small suspension engine, and the strong magnetism provides auxiliary buoyancy and" The role of traction positioning. In addition, the repeater has an engine transplanted from the drone as the final power, so the repeater that was blown away by the explosion quickly reset, causing the people in the camp to have a false alarm.

But this is a dangerous sign that the defender's defense is not without its weaknesses.

The man-eating birds apparently noticed this, and they circled for a while, then temporarily retreated a little farther away, and then formed a figure-of-eight formation and launched a suicide attack on the repeater in two groups.

Ah Jun immediately asked the inverter gunner to block it, but because the inverter gun was not powerful, the man-eating birds' successive suicide attacks worked, and the repeater was pushed out of the strong magnetic traction range, so he had to start the drone's engine to try to return to its position, but due to the impact of the explosion, three of the four engines were damaged before, and only one engine was left to support it, and it seemed that it was impossible to return to its position.

Mr. Tong came up and said to Ah Jun, "Sir, it's almost time. ”

Jun nodded.

Mr. Copper asked his assistant to push the remote control and pressed a button.

Theoretically, neither sound nor radio waves could be seen with the naked eye, but on that day, almost all the people in the camp swore that they saw a circle of repeaters that looked like a wave, and that all the man-eating birds fell in response to the sound of the wave.

But the explorers in the camp were all scientific, and they explained afterwards that the wave was definitely not an electric wave, and that it should be the high-intensity frequency conversion that caused the air to deform, just as we can see the air in the distant open field deformed by the heat in summer.

Everyone is open to this explanation.

Without the continuous attack of the man-eating bird, the repeater returned to its rightful position with an engine that was still intact, but the *** of its machinery to deal with the man-eating bird has been burned out, and it can no longer continue to deal with the attack of the man-eating bird, and now it can only be protected by the strong magnetic frequency conversion on the base.

Ah Jun gave the order to restore the communication relay and evacuate all the staff.

All this had been planned for a long time, so in a short period of time, not only was the airship fixed on the ground back into the air, but the receiving transport airship sent by the base camp also arrived. Ah Jun ordered all personnel to carry only their belongings and weapons, destroy the equipment, and leave only the communication repeater to continue its duty - to attract attention and reduce the pressure of being chased by the retreating personnel.

In addition, Ah Jun also left a video of sign language, telling the man-eating bird that we have decided to evacuate temporarily in order to maintain peace, but we already have weapons against you, so we will continue to gather in the base camp to accumulate strength. We will be back.

The retreat was smooth, but it also made many people puzzled - we obviously had the obvious upper hand, especially the last big killing weapon, and we were not afraid of how many man-eating birds came.

However, most of the expedition members have military experience, and their understanding and execution of orders are very good, and a few complaints do not affect the execution of orders.

Jin Junmei also had an opinion on this at first, but she had been staying in the command cabin since the beginning, and she had seen every movement of Ah Jun and Mr. Tong, so she guessed that the repeater was flawed, and it could not endlessly resist the attacks of the man-eating birds, and the place was not only a weapon of the man-eating birds, after all, she had fought with combat robots in the prison of Fortress Town, and knew the terrifying attack power.

In addition, the two guys who are most qualified to want Ah Jun to be coquettish, Meiya and Kekexi, did not have a superfluous word at this time, but obediently carried out the order like an ordinary warrior, and Jin Junmei was relieved when he saw them.

It's a pity that the iron cage she just arranged to serve as a boudoir can't be lived.

The evacuation process went smoothly, and the attendants of three communication stations were also carried along the way.

In fact, Mr. Tong and the others had left the base camp for less than a day and night, and the base camp had completely changed.

Dozens of construction machines began to push trees around the town to create "unsheltered areas", and the felled trees were cut into timber for the construction of fences, watchtowers, bunkers, shelters, and trenches, and the whole town was rapidly evolving into a complete field fortification.

Not only that, but evacuation missions were also underway, with airships carrying in combat sappers and supplies from various city-states overnight, as well as evacuating non-combatants and those who had not recovered from illness.

When Ah Jun got off the airship, he saw a well-equipped team walking onto the transport airship, as if to evacuate, which made him feel a faint sense of foreboding.

Jun hurried to the former conference room that had been converted into a temporary headquarters, where Irina and the military representatives of the city-states were lining up in front of the newly drawn map. Seeing Ah Jun coming, everyone immediately stopped what they were doing and applauded.

Ah Jun looked around at the crowd and did not find a representative of the steel city-state.

Irina stepped forward and pinned a pair of colonel ranks with the "Combined" logo on Jun's shoulder.

Ah Jun said: "I won't say anything about complaining, what is the situation now." ”

Irina led Ah Jun to the map and introduced: "The combined army is ready to deploy with a regiment (insufficient) of troops, and the troops in the town have been deployed, and the staff has already deployed sappers to open up an unsheltered area of 400 meters around the town, and is preparing to lay signal mines, ** and other explosive obstacles, you should see the construction situation outside on the way here." ”

Ah Jun nodded, looked at the representatives around him again, and asked, "What about the representatives of the steel city-state?" I could see someone evacuating outside. ”

Irina shook her head and said, "It's good to start talking about, the steel city-state is in charge of the main infantry defense and air combat forces. But suddenly it was necessary to evacuate, because the construction machinery could not be taken away, and it was also ordered to be destroyed. However, some officers and soldiers were so attached to us that they quietly left us some spare parts. ”

Ah Jun said: "Let's not mention friendship and reasons, how to fill this gap?" Is there a contingency plan? ”

"The representatives of the city-state have decided to recruit volunteers and form a mixed infantry battalion to fill the gap, and there are already people in the engineering unit who have expressed their willingness to stay and join the defense after the construction is completed," Irina said. ”

Ah Jun frowned and said, "That's two battalions at most, and the combat strength is insufficient." What about air power? ”

The military representative of the Ark Alliance said: "Originally, our side was limited to providing technical support, but I have already contacted the city-state, and a floating turret unit in my city-state is being assembled and will be there soon. ”

Ah Jun said, "How fast is it soon?" I need a specific time. ”

The military representative of the Ark Alliance said, "Two days. Until then, my drone swarm and the inverter weapons that we are working on together should be able to withstand for a while. ”

Ah Jun said: "The drone swarm should cooperate with the reconnaissance company of the tree elves to conduct reconnaissance and patrol, and drop the mixed turret troops in Fort Town, but the original firepower killing mission will not be canceled." In addition, let the troops of the Blackwater city-state hurry up. ”

Irina immediately adjusted this and organized it into an order to carry it out.

Subsequently, the military representatives of the city-states gave briefings on the mission, and Jun's decision was clean and eye-catching.

Jin Junmei originally thought that Ah Jun was an excellent bounty hunter, but she didn't expect to have such a high reputation, and she was quietly embraced as the field commander of the city-state coalition army, she felt that she should do something, so she applied to go to the mixed infantry battalion, but Ah Jun refused.

Ah Jun said: "You only have police training, not military training, so you are not suitable to go to the infantry battalion, so you should stay in the command headquarters, you also need people here." ”

Jin Junmei glanced back, and several female soldiers were using push rods to push various wooden markers on the map according to the instructions of the staff officers, and said, "Are you like them?" ”

Ah Jun said: "First, they are all very good, they know all kinds of military branches and troop formations and positions; Second, there are other jobs here, such as guard squadrons, gendarmerie squadrons, I think you are suitable to be a gendarme, so many veterans with blood rush together, there will always be endless problems of discipline that cannot be solved. ”

Jin Junmei asked rhetorically, "Is this an order?" ”

Ah Jun said: "Now it's just a suggestion. ”

Jin Junmei wanted to say something, but suddenly someone came in to report: caught a spy.

This can be regarded as the first living spy captured by the city-state alliance, so Ah Jun asked someone to be brought in, and he wanted to see it in person.

The man was brought in, along with a backpack he had with him when he was captured, and he was thrown on the ground.

Ah Jun looked at the man—a young man with clear eyebrows, and the old backpack, and he recognized him as Lin Cong, the little husband that Mrs. Zhuang had been looking for.
