What makes Lin Xiao even more strange is that this thing can order zombies, but it can't let the zombie group impact the wasteland team, the only thing that can be done is to let the group of ordinary zombies, even the zombies of the second and third evolutions, surround himself, in order to block the bullets of the wasteland group and achieve the purpose of protecting himself.

So, under the relentless pursuit of Lin Xiao and others, they finally followed this zombie to find the entrance to the secret research room, and successfully killed this one, which is likely to evolve into another special zombie of the zombie king in the near future.

Finally, when searching for the entrance to the research disguised as an underground garage, Lin Xiao found an anomaly, the garage was very clean, and there were a lot of monitoring equipment that was not a civilian device at a glance.

What makes Lin Xiao even more incredible is that these monitoring equipment are still operating normally! There are even quite a few monitoring probes, following their search track all the way!

After a closer search, Lin Xiao found the entrance, and because they were wearing camouflage uniforms obtained from the assembled troops, they gained the trust of the old pedants in the secret laboratory.

Seeing that there were already zombies outside, these old pedants were unwilling to give up the experiments that had been carried out to the end, although they could no longer receive any signals outside, they wanted to understand the reason for the disappearance of the signals.

In this case, Lin Xiao naturally waved his hand, and even received all the equipment with people, and there were a large number of scientific research equipment in the underground laboratory, as well as high-power oil engines, and high-power solar power generation equipment.

These things also happen to make up for the energy gap in the rock base, which can be described as killing three birds with one stone.

And after those old scholars were coaxed and tricked back, they had been in the laboratory and refused to come out, and they were forgotten by Lin Xiao, who was bent on opening up the wasteland.

"Let's go, let's go and see what those old men have found!" Lin Xiao thought of the major discovery that Wang Liang said, and his eyes lit up, and he hurriedly walked in the direction of the laboratory.

When they came to the laboratory, those experts and scholars had already sorted out the discovery report, although Lin Xiao may not be able to understand it, but if there is a discovery, it must be printed into written materials, which is the habitual action of experts and scholars in their work schedule for a long time.

"Elder Yang, I heard that you have made a major discovery?!" Lin Xiao didn't ink, and immediately asked Yang Chunlan, the person in charge of the laboratory.

The name Yang Chunlan sounds like a female name, but in fact, this Yang Lao is an old man in his early sixties, and he is quite burly, ignoring the gray hair on his head, he really doesn't look like an old man in his sixties.

"Commander Lin is here?" Yang Chunlan's eyes lit up when he saw Lin Xiao, at the beginning he was used to calling Lin Xiao Xiaolin, but just now Wang Liang had already told him the content of the decisions reached at the meeting, and it was a little inappropriate for him to call Lin Xiao Xiaolin again. The commander shouted awkwardly, and simply called Lin Xiao his military position in the base according to official custom.

"You're welcome, you still call me Xiaolin! The commander's shouting sounded awkward! Lin Xiao still respects scientific research workers enough, in his eyes, these are panda-level baby bumps!

"That's right, we've tried a lot of bands and frequencies of signals these days, and we've debugged all kinds of signal reception methods that we can understand and master, and finally come to a conclusion!" Yang Chunlan immediately cut to the chase, his personality and figure are very unified, and he is the kind of rough and direct character.

"We found that it was not that the signal disappeared completely, but that there was an additional factor in the air, this unknown factor, which could absorb any signal propagating in the air, including electromagnetic signals, electronic signals, and even sound wave signals! That is, this factor is in the air for a day, and communication equipment, reconnaissance equipment, including military radios, sonar detection, military radars, and so on, all fail around the world! ”

Speaking of this, the old man Yang Chunlan paused, and a gleam was removed from his eyes: "But this problem is not completely unsolvable, at least we have found a part of the solution!" ”

"Oh? So what do you have to fix it? How far can communication be achieved? Lin Xiao is most concerned about practical use, and the theoretical data in the laboratory is not reliable.

"Well, after repeated tests, we have basically mastered the speed at which the unknown factor in the air absorbs the signal, and theoretically, as long as the signal emitted by our device exceeds the speed of the signal absorbed by this unknown factor in strength, it is possible to convey a vague signal!"

"After testing, we found that as long as it can be stabilized at about 70 times the normal strength, it can ensure that the signal is smooth within 200 meters, and the signal is barely received within 500 meters.

"But ......" Yang Chunlan suddenly deflated, and the whole person hung her head: "Our existing equipment, the maximum strength that can be transmitted, is only 160 times the normal signal, that is to say, the maximum distance can only be stabilized in the range of 600 meters, and it also needs to send signals and receive signals synchronously, a slight delay will lead to the signal being completely absorbed, and it cannot be received!" ”

Nima ...... Rejoice in white! Lin Xiao was also speechless, what can he do at 600 meters? At this distance, the flag language is completely competent, if it is placed on flat ground, there is no other noise interference, even if it is shouted in the voice, it can be heard completely!

"Ahem, but Commander Lin, please rest assured, we already have a new plan and are currently looking for suitable materials and chips!" Yang Chunlan also saw Lin Xiao's disappointment, although he was very frustrated, but his eyes flashed with a light that did not admit defeat: "We believe that as long as we don't give up, sooner or later, we will be able to find a band or signal variety that this unknown factor can't absorb!" Electromagnetic signals don't work, sound signals don't work, let's try optical signals, or even quantum communication! ”

Well, Lin Xiao was embarrassed to pour cold water on people, so he could only frown and reluctantly cheer them up: "Okay, with Yang Lao sitting in the laboratory, and the all-out efforts of all scientific research workers, I believe that you will be able to overcome the difficulties in front of you!" ”

After coming out of the laboratory, Wang Liang looked at Lin Xiao with admiration on his face: "Tut, that sentence is really right, the position of the butt determines the height of the brain, look at you, now after sitting in the position of commander-in-chief, the commander-in-chief is much more level than before!" ”

"Fuck off!" Lin Xiao gave him an angry look, this thing is purely standing and talking without backache! These experts and scholars, seeing that they are about to give up completely, can they still be more frustrated than them if they don't encourage them?

If there is really no signal at all and there is no way to communicate, this is definitely the biggest flaw of human beings! If we don't find a solution as soon as possible, this hard wound is likely to lead to the destruction of humanity in the future!

Alas, it seems that Comrade Wang Liang's brain capacity is indeed a little too small! Lin Xiao looked very sad, and walked towards the headquarters by himself, he wanted to see his country again......

Just when everything was moving quickly in the Panshan base, in the mountains and forests less than 80 kilometers away from the Panshan base, a well-equipped special team was cautiously searching and advancing, but in the center of the formation of this group of special forces soldiers, a woman in civilian military uniform was guarded.

Judging by her age, this woman was only in her early twenties, but she carried the rank of lieutenant colonel on her shoulder, and she carried a black lockbox in her right hand, and there was a special pair of handcuffs on the handle of the lockbox, which was handcuffed to her wrist.

"There are about five kilometers ahead, and we are about to leave the mountain forest area, and we are about ten kilometers away from the nearest town, and there may be zombies at any time! Weapons that don't have *** remember not to fire! The captain-like soldier glanced at the individual computer on his wrist and reminded.

After getting the body language reply from the team members, the captain glanced at the sweaty female soldier in the middle of the team, and asked with a somewhat embarrassed face: "Director You, is your body still able to eat?" Maybe we should take a break? ”

The female warrior known as Director You is already very tired, but she knows very well that this team of soldiers who are responsible for escorting her is even more tired, and she also knows that time is life, and if she arrives at the secret laboratory one second earlier, the new equipment she carries will take effect a little earlier!

"No, I can hold on, we can move on!" Director You gritted his teeth and said.

"Change the formation, the side protection team will take turns carrying Director You, let's speed up and leave the dense forest first!" The captain hesitated for less than three seconds, and immediately made a decision, Director You's state couldn't last long!

There are still five kilometers of mountain road ahead, and it is about to enter a densely populated area, and Director You's body continues to advance for five kilometers, and when he encounters danger, he may not even have the strength to escape!

Even if you sacrifice the reconnaissance protection provided by the flank protection team, it is better than because Director You's physical strength can't keep up, resulting in the annihilation of the entire army!

What's more, the order given to him by his superiors was to safely escort Director You to the secret laboratory in H City at all costs, hand it over to Academician Yang to test the stability of the new equipment, and protect the smooth return of Academician Yang and his party!

The magnitude of the task was far beyond their budget, and the helicopter had not yet traveled 200 kilometers when it was attacked by a mutated empty bird, and although the empty bird was successfully scared off by the fire of the cannons, the engine of the helicopter was also destroyed.

In the case of helicopter control failure, the crew members hit a big tree with the cockpit in order to protect the people in the cabin, and the main and co-pilots were sacrificed, in exchange for the landing of the action team without injury.
