After the tool man strikes [Quick Transmigration]

In the original plot, almost one year after entering the end of the world, nature also began to attack human beings. A large number of insects, ants, birds, animals and aquatic creatures were also infected by zombie viruses and became extremely aggressive. They began to attack human bases. , Invading the already very narrow living space of human beings.

Many small and medium-sized bases were directly destroyed due to poor defense, and the number of survivors dropped sharply again. In the end, only a few large and well-defended bases remained, but it was inevitable that they would suffer huge casualties.

And because of various dangers in the outside world, the communication between bases has become extremely difficult, and each base has almost become an isolated island.Under such extreme conditions, the country's governance and management have become useless, and several major bases have begun to go their own way.

Later, the central base developed a zombie expelling potion, which brought a little bit of good news, but Han Ye held the things tightly in his hands, and the lion asked for various benefits, so he agreed to share a little potion with other bases. It is absolutely impossible to disclose.There are also other bases that have found other countermeasures, but some follow suit, only caring about their own development and growth, regardless of the life and death of others.

Those in power have their own selfishness, and the gap between the bases is gradually widening. The human survivors who should work together are divided into factions, and there have been many vicious competitions to suppress dissidents, which eventually indirectly led to the destruction of mankind.

But just like what Qi Han said, now that Han Ye is dead, the original plot is only used as a reference. The question Lin Lang is thinking about now is how to minimize the loss of human beings when the scope of infection is further expanded .

Leaving aside other places, the situation of the city S base is not very good.The base is relatively close to the sea, and the creatures in the sea will climb ashore after being infected with the zombie virus, heading towards the human settlements, and the S city base will bear the brunt of it.

The infection of insects and ants is even more terrifying, especially insects with strong reproductive ability such as flies and cockroaches. Once infected, a large area of ​​tens of thousands or hundreds of thousands, if a person in the base bites a few bites, it will be a disaster. .

Although the base now has an energy shield that can avoid many dangers, even if Lin Lang has improved it several times, this thing still consumes too much energy. It can still be used in emergencies such as zombie siege, insects and marine life. The number of zombies is several orders of magnitude more than that of zombies, and it is impossible to solve them all in a day or two. If the energy protection shield needs to be used for many years, the huge energy consumption base really cannot afford it.

In fact, some people have long foreseen the possible harm caused by insect infection. The base has always arranged people to carry out the work of "elimination of the four pests". However, it is impossible to prevent the small insects from being completely eliminated, and the threat from the ocean has not yet How many people realize.

Lin Lang has been doing research on these threats during this time, and he has found the direction, which is the zombie expulsion device he has studied before.

Now those few medical experts have stayed at the base in City S with peace of mind. The zombie expelling medicine will be researched sooner or later, but the medicine configuration is more complicated, the scope of action is small and the effective time is short. The base is a bit stretched.

What Lin Lang wants to research is a reusable zombie expulsion device that can act on the entire base for a long time.

The previous research has been unremarkable. Instead, a sinister gadget was created by accident. These days, I finally got some inspiration and designed the general structure of the device.

This time, the fantasy refining method was adopted, combined with the refining principles of several sound attack weapons in the cultivation world, to design a device that could continuously release ultrasonic signals that disgusted zombies.In the future, various experiments are needed to avoid the harm caused by the device to humans, increase the signal types, and ensure that it is effective for any species of zombies such as insects and rats.

This day, Lin Lang had assembled the zombie expelling device and was about to go out to find zombies to verify the effect. The base chief suddenly came to his studio, sat on the sofa without saying a word, and stared at him with a complicated expression.

Lin Lang didn't bother to guess what he meant, so he ignored him and just packed his things. After about ten minutes, the base chief finally couldn't help but said, "Expert Lin, no, boss Lin, what do you think of me? Like? Mainly... how does it treat you?"

Lin Lang glanced at him lightly, "Speak humanly."

"Just tell me if you're satisfied with me."

"How about satisfied, what about dissatisfied?"

The base chief sighed, and said with a serious face: "I just got the news this morning. Yesterday, there was a big explosion in the central base, and many people died."

"I heard that there is an organization in the base. The leader illegally imprisoned several researchers and forced them to do research for himself. As a result, the leader accidentally died outside, and the organization was in chaos. Those researchers were also capable. Not only did they take advantage of Luan escaped, and made a few bombs, which killed most of the people in the organization. I heard that several high-level officials of the central base happened to be inside, and they were all killed. Now the higher-ups have to redeploy people to manage What about the base?"

"By the way, the leader's surname is Han." The head of the base apparently also heard about Lin Lang's killing of Han Ye, so he glanced at him indistinctly, and said, "Lin Lang, the base has never forced you to You don’t need to be burdened by how many results you want to research, if you are not satisfied with us, you must speak up directly, don’t hold it in your heart.”

Hearing the bad news about the central base, the head of the base deeply understands how terrifying it is for someone capable of attacking ruthlessly. Lin Lang is much more powerful than those few researchers. If he has hatred for the base, The whole base is not enough for him to blow up, no, hurry up and say hello to Lin Lang.

Lin Lang lowered his eyelids and did not speak.

I didn't expect that after killing a Han Ye, there would be such a chain of events. The group of Han Ye's men would be killed, which seemed to have something to do with him indirectly.

No, one cannot fall into such a vicious circle of logic.Han Ye imprisoned and oppressed those researchers, which was the root cause of the explosion. It is impossible for the victim to retaliate violently against the perpetrator after being rescued. Instead of investigating the problems of both parties, blame the police who rescued the person.

Seeing that Lin Lang was silent, the head of the base seemed to have guessed what he was concerned about, and added casually: "Fortunately, the explosion did not hurt innocent people, and those researchers are also very interesting. They didn't run away after making the explosion. He even sneaked into the broadcasting room of the base and confessed his crimes to everyone in the base."

"However, they also made public all the murders and collusion with officials by the people in the organization surnamed Han. I heard that people in the base are now saying that they bombed well. In my opinion, more than They are more suitable for doing propaganda work together.”

Lin Lang raised his eyelids and looked at him silently for a long time before he said, "I know, I will come to you directly if I have any dissatisfaction in the future. Are you free today? Are you still leaving?"

Base Chief: "...Let's go."

He felt like an old father who tried his best to be good to his children, but was ruthlessly rejected by the rebellious children.

"Old father" sighed and walked out with his hands behind his back. Lin Lang added behind him: "There is a research that will come out in a few days. Remember to come and see it when the time comes. Also, thanks."

It's not that he doesn't know what to do, of course he knows that the base chief's long-winded words are to reduce his psychological burden, and he accepts this favor.

The experiment of the zombie expulsion device went smoothly, and it took Lin Lang more than ten days to adjust and improve the details before reporting the results.

Knowing that those medical experts were also doing research in this area, the base director couldn't help but feel a little annoyed, "Expelling zombies? It overlaps with Academician Fu's research. I should have told you earlier."

"There is no overlap," Lin Lang explained to him the special feature of this device. "The medicine is sprayed and used immediately, which is convenient to carry, but it also has disadvantages. This device needs to be set up in advance. It has a large range of action and is suitable for placement in bases. There are various uses."

Hearing what he said, the base chief also wanted to understand, and nodded again and again: "Good thing, you have made another great contribution this time!"

Lin Lang put forward a different condition from the past, "I will make a few more sets of the core of the device in the next few days, and the rest of the parts just follow the drawings. I hope you can spread this technology as soon as possible so that other bases can quickly use it." superior."

"So anxious? Is there any reason?"

Lin Lang said in a deep voice: "In the past few days, I have seen a lot of rats outside. If they are all infected, humans can still survive? There are also flies and cockroaches, there are many in the base... ..."

Hearing his description, the base chief couldn't help but shudder, "Indeed, the sooner you use this thing, the better. I'll report it to our base after it's successfully installed and tested, otherwise the higher-ups may not believe it."

In the next few days, Lin Lang frequently squeezed Kepi the dog, and copied many sets of the core parts of the zombie expelling device. After the device was installed in the city S base and verified that it was really easy to use, the base chief reported the technology and said that other bases could come to pick it up at any time if they needed it.

So for several days, people from other bases frequently visited base S. They knew that the zombie expulsion device was a good thing, and they were too embarrassed to ask for it for nothing. Most of them brought some supplies and other technologies in exchange. After receiving the good things The base chief himself was not greedy, and sent most of them directly to Lin Lang.

That day, Lin Lang heard the roar of the helicopter again, thinking that someone from another base had come, but not long after, someone knocked on his door, "Brother Lin, open the door quickly, Brother Lin, I'm here!" It's Qi Han, I'm here to join you!"

Qi Han was carrying a sports backpack, which contained a change of clothes. According to him, he took out all his belongings, including the protective cover given by Lin Lang, and exchanged a helicopter full of energy with the capital base. , so he drove the helicopter with empty hands to seek refuge with Lin Lang.

"Brother Lin, I have nothing now, and I will hang out with you from now on!"

Lin Lang: "...Where's your eldest brother, where are your parents, don't you care about them?"

"They are doing well. I said harsh words. If I can't become a martial arts master, I won't go back. Brother Lin, you must help me!"

Lin Lang: "..."

He didn't know whether to say that this young man was open-minded or heartless. He knew that he was a character in a novel and could live so freely, so it should be the latter.

Qi Han just relied on Lin Lang to live in the S city base.

Soon after, there were frequent changes in the ruins of the city and in every corner of nature, and another wave of storms in the last days was coming.
