Just as everyone was cheering for the victory, the nano-sensor sounded the alarm again, and this time it was louder and more compact than before.

Everyone looked at the nanosensor's display, and there were more big red dots on it, about hundreds. Before he could catch his breath, danger came again.

At this moment, Lin Yifan suddenly shouted: "Hurry up, everyone hurry up and enter the wall!" ”

The password has finally been unlocked, and Lin Yifan has taken control of the power grid. Everyone heard Lin Yifan's words, and tried their best to climb into the wall with their last bit of strength. When the last person entered the fence, Lin Yifan turned on the power grid as soon as possible.

There is a small energy supply machine underneath the center of the wall, which can continuously supply energy to the grid, so the inside of the wall is equivalent to a safe zone.

Soon a number of swamp beasts appeared in the grass, wandering around the wall, with a fierce look in their eyes and a mucus mouth that kept growling.

Surrounded by the dense swamp beasts, all the freshmen were filled with fear, and they had never encountered such a scene since they had been trained.

The swamp beasts stared at the blue-white grid, and one of the larger swamp beasts suddenly roared, and then pounced on the wall.

When all the freshmen saw this scene, they all pinched a cold sweat in their hearts.

I thought to myself, "It's not going to rush in like that, is it?" ”

As soon as the swamp beast that pounced on it touched the power grid, it was immediately bounced off and fell heavily to the ground, its body was still glowing with blue-white electric light, and it ran out of breath after a while, and a trace of bright red blood overflowed from the corner of its mouth, and a scorching smell instantly spread in the jungle.

When the other swamp beasts saw their companion dead, they no longer dared to take a step forward.

"Captain Lin, it's not a long-term solution for us to be surrounded like this, should we just give up?" Li Hu was pacing anxiously on the side.

"Captain Li, don't worry, there will be a way, open these boxes first and see what there is!" Lin Yifan comforted.

Everyone lifted all the boxes together, and then opened them one by one, and everyone opened their mouths wide as they looked at the equipment in one place.

Military electronic helmet, equipped with far-infrared sensing perspective, aiming locator, radio communication equipment.

Light military individual armor, equipped with electromagnetic pistols, multi-functional military knives, individual electromagnetic rifles, armor surface and heat insulation, fifty meters away will not be scanned by infrared sensors, there is also a regulator inside, not only can control body temperature, but also can discharge excess water and moisture in the air of the human body, absorb and filter into drinking water.

A multifunctional military backpack equipped with a large amount of food, medical supplies, and a small amount of water.

The combination of the three pieces of equipment is a complete set of individual equipment, and according to the number, there are about ten sets.

In addition to these, there are toolboxes, long-range scanners, climbing tools, and electronic instruments.

Seeing these equipment, all the freshmen, as well as Wang Xiaopang and Li Hu, were happy at this time, and even the crisis outside the power grid was left behind.

What makes them happiest is not only these equipment, but also many beacons, and sure enough, the benefits are directly proportional to the dangers.

Wang Xiaopang looked at these equipment and exclaimed excitedly: "Boss, we have made a lot of money this time, this battle is really not in vain!" ”

But Lin Yifan didn't pay attention to Wang Xiaopang's words, but stared thoughtfully at the last big box that was opened. Seeing Lin Yifan in a daze, everyone's eyes followed him to the last box.

The last box contains a group of military reconnaissance drones, usually in groups of twelve.

Li Hu stepped forward curiously and asked, "Captain Lin, what's going on, what are you thinking?" ”

Hearing Li Hu's question, Lin Yifan looked back at everyone and smiled: "I have a way to break through!" ”

Li Hu and everyone looked at each other and asked suspiciously, "Captain Lin, do you want to use these unmanned aircraft?" But these are all reconnaissance drones, and they can't fight! ”

Lin Yifan picked up a drone and said, "Yes, these are unmanned aircraft." Although they are reconnaissance aircraft, they are not ordinary, but military. I can convert them into combat drones. ”

Military UAVs are not of the same grade as ordinary ones, the materials used are strong and very light, the core energy can make UAVs continue to fly for 48 hours, equipped with micro supercomputing, long-distance communication transmission devices, multi-functional electronic scanners, ultra-clear image capturers, long-range infrared beam guidance locators.

Lin Yifan used the infrared beam released by this guidance locator to modify it into a weapon. Using the radiation characteristics of the beam, Lin Yifan changed the emission focus, so that the original fan-shaped positioning beam gathered into a small beam, and then increased the output power, although the core energy consumption is very powerful, but the power is equivalent to a light laser pistol, and the heat energy released is enough to penetrate the skin and flesh of the swamp beast.

After two or three hours, the modification was finally completed, during which Lin Yifan, in order to ensure the safety of the peripheral personnel, used his personal terminal to contact Shangguan Yuyan, asked them to stay a little away from the entrance, and found a more private place to wait.

In addition to Wang Xiaopang and Li Hu, Lin Yifan also selected a few more powerful team members to put on individual armor, and the rest were also allocated some equipment, and arranged a few students with greater strength to take turns carrying the remaining supply boxes.

The swamp beasts that surround the perimeter of the power grid wall still linger around. Obviously, this group of beasts is very warlike, staring at the black hole with their eyes, and their eyes are extremely fierce, eager to eat people in one bite.

Lin Yifan used the underground small energy supply machine to charge all the drones, it took about an hour, all the drones were charged, the preparations were basically completed, and now it was to clean up these swamp beasts.

The team was still lined up in two lines, and all the team members held spears in their hands and waited for Lin Yifan to open the power grid wall. Although Lin Yifan was very confident in the drones he modified, for the sake of insurance, only one of the drones was activated.

I saw that the power light of the drone flashed, and the four rotating wings began to rotate at high speed, and then slowly lifted into the air, although the speed was very fast, but there was no sound at all, which is the benefit of high-energy materials.

Lin Yifan first let the drone do a few simple flights in the space of the power grid, and the result was very satisfying, worthy of the military version, the flight action is very flexible, and the speed is very fast.

These modified military drones are easier to control than ordinary military drones, before the modification is to use the operation panel to control, and Lin Yifan's talent is not comparable to ordinary people, he used a microcomputer to write a voice control program to input personal terminals and UAVs Micro Supercomputer, use the remote communication of personal terminals and UAVs to establish a link, just speak to the terminal to control the UAV group to attack the target.

Everyone looked at the drone flying around in the air, except for Wang Xiaopang, they were all surprised, they didn't see any control disk in Lin Yifan's hand, but he could make the drone fly in the air flexibly, and he was also doing all kinds of difficult actions.

At this time, everyone was even more in awe of Lin Yifan, not only did he have good fighting skills, but he also had excellent high-tech knowledge, this was the strength gap.

After a few minutes of experimentation, Lin Yifan decided to let the drone fly out for actual combat. He activated the power grid to break through a gap, and the drone, with a "whoosh," flew out, hovering ten meters above the swamp beast's head.

The swamp beast standing under the drone looked directly at the drone, and after a while, suddenly raised its head and screamed, jumped up a few meters high, and then stretched out its claws to grab the drone.

The drone did not move in place, which made everyone's hearts cold. It's not going to be crushed like this, is it? Just when everyone felt that the situation was not good, the swamp beast ran out of strength and fell down when it was still about two meters away from the drone.

The swamp beast couldn't jump that high, and that's when everyone breathed a sigh of relief. Then the drone's infrared shot suddenly lit up, shooting a thin dazzling red light at the swamp beast's head.

Then I saw a puff of blue-white smoke coming out of the swamp beast's head, and a miserable scream followed, only to see the swamp beast fall to the ground and twitch a few times and never move again.

Seeing the motionless swampmon, a freshman asked, "Dead, was the swampmon killed?" Everyone looked at each other.

Without waiting for everyone to react, Lin Yifan had already activated the other eleven drones. "Whoosh, whoosh, whoosh," the sound of breaking wind burst through the cracks in the power grid, neatly arranged in a line and hovered over the swamp beast.

Seeing the drone swarm, the swamp beasts roared wildly, and some even jumped upwards with all their might, trying to knock down the drone swarm with their claws, but no matter how hard they tried, they couldn't touch the drones.

Lin Yifan gave an attack order to the drone group, only to see that the drone group released more than a dozen red rays and shot into the heads of more than a dozen swamp beasts, and then puffs of blue and white smoke came out one after another, and more than a dozen swamp beasts were already killed.

Looking at the fallen kind, the rest of the swamp beasts screamed even more frantic and ferocious.

As time passed, more and more swampmons fell to the ground, and the swampmon's counterattack could not hurt the drone swarm at all, and then the beasts seemed to sense the danger, and one of the swampmons, which was slightly larger, raised its head and ran towards the depths of the grass, and the other swampmons also fled into the depths of the grass with it.

Looking at the evacuated beast herd, Lin Yifan withdrew the drone swarm. For the sake of safety, he did not immediately lead the team to transfer, but replenished the energy of the drone swarm, because the energy consumption of launching the red mang is huge, so the drone must be fully charged before leaving.

About fifteen minutes later, Lin Yifan turned on the remote scanner, he was afraid that the swamp beasts would ambush around and wait for them to come out of the power grid for protection. However, there was no abnormality within a radius of two kilometers, but the swamp beast had special secretions that could avoid heat induction scanning, so Lin Yifan sent a group of drones to search nearby.

After searching for about ten minutes, the drone swarm did not find the shadow of the swamp beast. Lin Yifan contacted Shangguan Yuyan and told them that the crisis had been lifted and they were ready to leave the supply point.
