Outside the supermarket, Luan Yue brandished a baseball bat and smashed the heads of four zombies in a row with a strong force that was not weaker than a home run. Chen Ying, who was waiting next to her, immediately followed, slashing at the zombie's buttocks with an axe, collecting the stones in the zombie's head.

"Hey! You two can go in, the zombies in the supermarket have been disposed of, see what everyone needs to go in and get it! Jiang Sen and Wang Muyan pushed two shopping carts full of food out of the supermarket, and then Luan Yue and Chen Ying put away the stones on the ground and ran into the supermarket.

Soon, the rear trunk of the Mercedes-Benz SUV was filled with all kinds of supplies, the car engine roared, Luan Yue threw away the bloodstained baseball bat, took a new baseball bat just obtained from the supermarket and Chen Ying, quickly got into the car, Jiang Sen stepped on the accelerator, and drove the vehicle towards the west of the city.

Sitting in the car, Luan Yue picked up the metal tube containing the stones, approached his eyes and looked at it curiously, and asked suspiciously: "This thing can really strengthen bones and make the user stronger?" ”

Jiang Sen raised his head, glanced at the rearview mirror, and said lightly: "It's a fact that the team has more manpower than you, and it's also a fact that your strength is increasing." ”

"It's true, especially after eating that red liquid capsule you gave me, I feel like my strength is growing faster! By the way, what's in there? Yingying said it was blood, I don't believe it, how can blood have the effect of enhancing strength, I don't think it~! ~~~, Yingying, why are you pinching me. Before Luan Yue, who was sitting in the back row, finished speaking, Chen Ying, who was sitting next to him, pinched his thigh fiercely.

"Poof!" , Wang Muyan, who was sitting in the co-pilot, couldn't help but smile, and Jiang Sen also smiled helplessly at the two people behind the car through the rearview mirror.

"Sen, Brother Sen, I, I, I'm just curious." , Chen Ying lowered his head like a child who was sitting on the wrong side and admitted his mistakes, Luan Yue looked at it puzzled, he was really puzzled, because his strength was really strengthened after taking the stones, especially after eating the red pill that Jiang Sen gave him, he thought that he was going to become a superman and found that not only was Li Tao's strength greater, but even Chen Ying couldn't compare, just yesterday, the two of them had just wrenched their hands, and his thick hand could top twice the area of Chen Ying's palm, but even if he was holding Chen Ying's one hand with both hands, Luan Yue was suppressed by the other party.

"It's okay, we're a family, don't say anything sorry, there are some things, it's not a good thing for you to know more. The strength of all of us is growing, and it would be nice if we could survive in the last days. But you have to be optimistic about this fool around you, don't say everything, "Huaibi is guilty", some things may cause us trouble. Jiang Sen drove the car and glanced at Chen Ying through the rearview mirror with a smile.

The girl replied to Jiang Sen with a smile, and pinched Luan Yue beside her fiercely, as for betraying Jiang Sen and betraying the team, this is an incredible thing in the girl's mind.

Soon, the vehicle carried the four people back to the convoy camp outside the city, the convoy had been driving for three days in a row, and the convoy was here for a full day of rest today.

While sharing a variety of supplies brought by Mercedes-Benz SUV with the team, the central meeting room of the Americas, the luxurious hall is resplendent with gold.

"We need vaccines."

"Without immunity, it's impossible to block the attack of mutant creatures!"

"What exactly is the Military Research Institute doing? Didn't the Institute say that things were going well before the disaster struck? Why is the vaccine not yet mass-produced! ”

Looking at the thick stack of reports on the table, John . . . Morgan's eyes showed undisguised helplessness and anxiety.

The remnants of the Morgan Corps of the American Southern Group, returning from the Southern Front, are being replenished with personnel and weapons. Surprisingly, officers at all levels of the unit did not seem to care about this, and the two most frequently used words in their combat reports were "vaccines."

The Morgan Corps said that it had first deployed two integrated divisions in the southern United States, and that when they set out, both integrated divisions were at normal full strength, with more than 40,000 troops. However, the number of survivors returning from the front line is only 10 percent of this number, which makes the Morgan family suffer a heavy loss.

More than 90 percent of the battle losses already belong to the category of being "completely annihilated." However, in the casualty statistics of the two divisions, the figure under the column "Killed in Battle" only accounts for 17 percent of the total number of soldiers.

The rest, all wounded. Either they lost their hands and feet, or suffered minor injuries that were not fatal, and none of them survived. According to the order, all the wounded must be "treated" within six hours. Tens of thousands of wounded who were identified as wounded, regardless of their severity, were killed on the spot.

Fighting zombies, injury means death.

The series of cold numbers on the report form made the Morgan family a little unacceptable, in the unstable last days, human resources are precious, but if the Morgan family can't deal with the zombie herd in the south and restore crude oil production in the Gulf of Mexico, then when other families grow and develop, the Morgan family is stagnating, or even regressing.

Once the time limit is exceeded, the wounded soldier will be infected with zombies, and the vaccine, the Morgan family, or every family, needs a vaccine.

"The research on zombie viruses in our institute before the disaster broke out was indeed progressing rapidly, and everyone here was injected with zombie viruses, but now we can't achieve mass production, and we lack one of the most important raw materials."

"What raw materials? I think it's just that you damn yellow old man is not capable enough! I really don't know how everyone was fooled by you and pushed you to the position of director of the research institute. ”

A yellow-haired old man with white hair but who looked very energetic, with a disdainful smile, said: "Hehe, it's a matter of skin color again, why is the research on vaccines and genetic boosters progressing slowly, it is because your military has lost Reagent Zero, and all the research on zombies has been carried out according to Reagent Zero, and all of you here have lost Reagent Zero for your own interests, why can you use the reagent Zero transported by air, and what did the second son of your Morgan family do when he went to Los Angeles?" ”

Meetings always break up unhappily, and no one wants to openly admit their incompetence and mistakes.

Central Academy of Sciences of the Americas, 1:15 a.m.

A luxurious Lincoln car drove into the underground parking lot of the institute with Zhang Weiying, the dean of the institute who attended the conference.

Waiting next to the parking space was a girl with glasses, she was wearing a wide white uniform, which could not hide her curvy and proud figure, and her slender and straight neck had a snow-like whiteness, although she did not wear makeup, her simple face showed a clear beauty that most women were jealous of. In particular, the coldness and arrogance that emanated from her made people feel a kind of latent temptation and unapproachable chill.

When Lincoln stopped, Lu Bing stepped forward and opened Lincoln's car door, Zhang Weiying got out of the car, "Teacher, what's the matter, look at your face, today's meeting was scolded again." ”

"Hahaha, why do you little girl know so much! How's your research going? Lu Bing came to the United States from Huaxia to study for a postdoctoral degree, and Zhang Weiying is her mentor.

The beautiful Lu Bing frowned slightly and shook her head.

"Like all viruses, they must be parasitic in living cells and multiply in a replicative manner in order to survive.

It is not a parasitic concept, and words such as "seizure" and "plunder" seem to better describe its terrible character.

The virus has a high degree of parasitism, completely dependent on the energy and metabolic system of the host cell, obtains the substances and energy required for life activities, leaves the host cell, it is just a large chemical molecule, stops moving, can be made into protein crystallization, for a non-living organism, encountering the host cell it will show typical life characteristics by adsorption, entering, replicating, assembling, and releasing the daughter virus, so the virus is a primitive life form between living and non-living things. ”

Zhang Weiying walked towards the research room and continued to speak: "It is completely different from a virus in the ordinary sense. The zombie virus also relies on the host cell to maintain life, but forcibly changes the human DNA chromosome, I believe you already know this, the effect of this zombie virus on DNA is chaotic and complex, some add chromosomes to DNA, and some instead devour the chromosomes of DNA, this impact on DNA directly controls the zombie from human to non-human. This has been proven from multiple zombie research experiments.

The first difficulty in fighting the zombie virus is that this is the first time that all human beings are facing a new form of virus, before this, although we humans have made rapid progress in the field of genetic research, but this kind of research has made slow progress in the study of human species because of moral constraints, and the zombie virus is a systemic form of action on human species, it can be said that this is a new field of human research, but the zero reagent has given us a lot of help, that is, with the zero reagent, We've just developed a zombie vaccine. But we can't achieve mass production of zombie vaccines, what we are looking for is a zombie vaccine that can allow us to inject into the human body with enough energy carrier, on the one hand, so that the zombie vaccine will not infect the vaccinated, and on the other hand, with enough strength to make the human body produce zombie virus antibodies. We already have a vaccine, but what we are missing now is an important carrier. ”

"Teacher, what did you say those zombies survived me, our test subject has not been fed since the outbreak of the disaster, but why is it still alive?" , Lu Bing followed behind Zhang Weiying and said his problem.

"Energy is always conserved, and the kind of power that supports the survival of zombies is what we need."

"Then teacher, why do you always mention reagent zero? Isn't our research on Reagent Zero already 80% progressive? Reagent Zero shouldn't be that important to us, right? ”

"Because the bastards in the military lost him, and it was their fault. The slow progress of research in our Academy of Sciences needs an excuse. ”

The communication between the two was conducted in Chinese, and Zhang Weiying would not say so much to anyone except Lu Bing.
