After reading the letter of inquiry sent by the head of the military region in a hurry, Zhang Han's sad face was about to drip Coptis chinensis, you said that he was a forensic expert with the name of a forensic doctor and a pharmaceutical torture expert who worked in a special department, and he was quite confident in the knowledge of pharmaceutical identification, after all, he relied on this to eat, even if forensic science was involved, after all, in the name of forensic medicine, it was really difficult for some strong people to replace it with viruses, bacteria, and genetically modified organisms. How to explain it in a simple and easy-to-understand way, and not let the leaders understand the mistakes lest they misjudge the future epidemic prevention work, that is a big problem.

After sitting in a daze for more than ten minutes, Zhang Han sorted out his thoughts and connected the video communication of the head of the military region, because he had no military rank and no need to salute, and after a brief exchange with the chief, he said bluntly: "You must have heard the concept of genetically modified, transplanting the biological characteristics of one organism to another organism, such as making cotton secrete a pesky smell of pests, or making apples bear fruits similar to Ya pear, etc., to achieve this effect, scientific researchers need to make a specific carrier, Replace the DNA information in the target cell with specific DNA information, so that the plant will grow a specific fruit according to our needs. It's the same with animals, but the carrier is much more complex than that of plants, and people, to put it bluntly, are also animals. ”

"Well, I understand this, but what do you mean by the repeated mention by experts that universal carriers will cause unpredictable disasters?"

"The analysis results of the Americans are that this retrovirus-like DNA information vector is artificially made, very versatile, and should be used to make genetically modified drugs...... Let's put it this way, if we want to build a house, we need a car to transport muck, we also need a cement truck, we also need to transport steel bars, different vehicles can only transport different building materials, this is certainly not efficient, but the house building materials because of the restrictions of the type of vehicle transportation, there will definitely be no mistakes, and there will be no problems with the house. If there is a car that can complete the functions of the above three types of cars or even more, it is much easier and more convenient to build a house, but if a vehicle that is too general is to transport a car of explosives to the house, the house built with explosives will explode sooner or later. ”

"So this outbreak is due to the transport truck pulling the wrong material?"

"Yes, that's the way it is! What's more dangerous is that after the building is built, the vehicle that contributed to the construction of the building will also stay in the building, if it is a specific vehicle, of course, it is fine, and the vehicle will definitely be useless if it loses the corresponding building materials, but the vehicle with strong versatility is different, and it can transport various building materials also means that it can transport something else, change the structure of the building again, and even eventually affect the function of the building itself. Zhang Han spread his hands.

"I see." The chief frowned and continued to ask: "It is difficult to infer the development of the epidemic that the experts said next is because no one knows what general vehicles can do. ”

"Yes, yes. According to the analysis of the Chinese Academy of Sciences, the pathogen of this similar retrovirus should not carry many types of DNA information, and there should be no more than six kinds of DNA information from the analysis of DNA molecular linkage patterns, but it is now commonly present in the body of infected humans, and the types and quantities of biological information that those zombie humans can be exposed to are simply immeasurable, and it is impossible to infer what kind of changes can occur. ”

"Will it change the way it spreads, like in the air?"

"No one can say for sure......"

Before he finished speaking, the head of the military region made a gesture to stop the communication, didn't even say a word, and then cut off the video and left Zhang Han directly in front of the computer.

'What's going on?' Something went wrong? Zhang Hai was stunned, confused.

Of course he didn't know, something was wrong.

Something big is wrong.

Wang Chen's eyes were quick, and the leg of the chair in his hand slapped directly on the temple of the zombie picket! The iron nail grazed the crooked helmet and poked into the head of the zombie picket, seeing that the bloody and one-eyed picket on his face was blurred, and the one-eyed picket stopped, the blood-red eye went straight up, and the black eye completely disappeared into the eyelid, and then, his eyeball was completely washed out of the socket by the blood that spread wantonly in the skull, and the broken brain tissue also shot out with the splash of blood, and the zombie picket fell to the ground softly and motionless like a breathless ball.

Seeing that the zombie picket was killed, Wang Chen and Hu Chun breathed a sigh of relief at the same time, and at the same time turned their heads to look at Li Changhuai, who was holding a pistol, and the latter was full of embarrassment: "That...... Careless...... Gone off the rails......"

Hu Chun threw the pistol and spare magazine to Wang Chen, who had already reached out and took Li Changhuai's gun, and was about to open his mouth to say Changhuai, you don't know how to use the gun first, use the chair legs, so that everyone is safe, and so on, a few low roars have begun to echo in the corridor.

The sound of gunfire alarmed the zombies.

Yes, it seems that God doesn't give Hu Chun a chance to speak.

Wang Chen and Hu Chun had a tacit understanding, and the two of them pushed open the door of the corridor at the same time, one looked up, the other looked down, and almost at the same time flashed back and closed the door.

This road is not working.

"I can't go this way, try my luck on the other side of the stairs." Hu Chun pulled off the belt of the zombie patrol and began to tie up the door.

"Go back to the house and take Han Li, let's go out like this, there is not much chance of coming back." Wang Chen suggested.

Looking at this posture, all the buildings are zombies except for the dead, and leaving Han Li in the house is no different from leaving her to die.

The three of them are not the masters who abandon their companions, and if they were really that kind of people, they would not have come to this point together, there was no superfluous nonsense, they rushed back to the house and ran away to set Han Li up, and in such a short time, the door of the floor that was originally wrapped in the belt has been pushed open by the zombie group, and the zombies of the three or three sirred staggered towards the corridor and even the room where the door was opened.

Wang Chen rushed to the end of the corridor on the other side with a pistol, pushed open the floor door, first let Li Changhuai and Hu Chun go downstairs, turned around and looked for it, just saw that the grip of the fire extinguisher was the right width, and hung it on the doorknob as a padlock, and hurriedly followed his companion downstairs.

It's a second to be able to drag it out!

Rushing downstairs, the three of them gasped three times as many as dozens of staggering figures on the playground, as for the other few zombies who were squatting on the ground and tearing blood and food, they didn't have time to count at all, the three of them subconsciously squatted on the ground, three pairs of eyes stared, and they had no idea for a while.

"The front door is locked, you need to go into the control room to open the door." Hu Chun's tone was hurried, and he suggested simply and directly.

"What about a car hit?" Wang Chen glanced at the seven or eight zombies wandering around the guardhouse, and his tone of voice was unconfident.

"I've seen similar ones when I was working before, the door is at least 20 millimeters (two centimeters thick), not to mention dead, it's still a slide, it's difficult." Li Changhuai is naturally professional in architectural decoration and technically denied Wang Chen.

"Get the car and rush to the guardhouse to open the door, Cao Baoquan must have the car key." Hu Chun revised the plan.

There was a faint popping sound at the entrance of the building, obviously the sound of something rolling down the corridor, the time was tight and the three of them were not allowed to think about it, Wang Chen gritted his teeth and said: "Cheng, it's a gamble of death or life!" ”

At this time, using a gun is to find death, and it is inconvenient to move with Han Li, in terms of hand-to-hand combat ability, Wang Chen must be at the bottom, he simply carried Han Li on his back and liberated Li Changhuai, Li Changhuai was not hypocritical, he took a chair leg in each hand to protect Wang Chen, and Hu Chun, who had the greatest strength, simply carried a fire extinguisher as a hammer to open the way, and touched the office of the auxiliary building under the cover of flower beds and bushes.

The sight is not good when night falls, and the zombies are based on instinct, and they distinguish the target more through their sense of smell and hearing, so those flesh and blood really helped the three of them a lot, and the smell of blood and the smell of human fresh internal organs are combined, and it is strange if the rich smell can't attract zombies.

Unexpectedly, the three of them had just slipped across the square, and there was still a distance of twenty or thirty meters from the annex building, and there was an almost inaudible sound of vomiting diagonally across the square.

The zombies who couldn't squeeze into the position and were wandering around turned around almost at the same time as the vomiting sound came out, and staggered towards the place where the vomiting sound, the person who made the vomiting sound realized that he had made a big mistake, and in the panic, he probably fell or hit something, and at the same time made the noise, he couldn't help but let out another scream!

This is good, not to mention the zombies who have no goal, the zombies who are enjoying the blood food are also alarmed!

Seeing the zombie group moving to the other side of the square, the three of them hurried to the southeast entrance of the annex building, not that they were cold-blooded, if they wanted to rescue, they had to see if the three of them had the ability, with such a living burden as Han Li and wanted to be a hero, it was the head that was in the water, leaving Han Li and rushing up, the bullets were all over and surrounded by zombies, which was also the end of being buried in the mouth of the zombies.

Instead of watching the play here, it is better to hurry up and find the keys to the military car, maybe that unlucky guy has a chance to hold on until the moment when the three of them get in the car and evacuate!

The energy-saving lamp at the entrance emitted a soft white light, and there was no one standing in the picket position, Hu Chun strode into the building with a heavy fire extinguisher, and was facing a young zombie swaying left and right, he didn't even think about it, picked up the fire extinguisher and hit the zombie's head!

Right on top of the zombie's head!

At the same time, Li Changhuai turned sideways around the smashed zombie, raised the chair leg in his hand high, and aimed at the temple of the second zombie and turned it down!

With Hu Chun's strength, this smash couldn't be more realistic, the zombie's entire head was suddenly deformed, and both eyes were smashed out! Because the sight was blocked by the zombie companions, the second zombie didn't react at all, and he didn't even raise his hand, and was easily succeeded by Li Changhuai, so the two zombies were almost like cutting a wooden stake, and they fell to the ground almost at the same time!

Wang Chen, who finally entered the building, put down Han Li in a half-squat, closed the aluminum alloy door with his backhand, leaned against the door and looked at the square, and said in a low voice: "There is no movement outside." ”

"Let's go!"

Cao Baoquan's temporary office is on the first floor of the annex building, which was originally the duty room of the doctor in the nursing home, next to the medical room, to make it easy to enter and exit, saving the three of them the time to climb the stairs in fear, and the few cloves of garlic in the corridor are not enough to clean up the red-eyed Hu and Li, of course, if the corridor is full of zombies, even if these three A have pistols in hand, they can only escape.

Seeing that there was no threat of standing in the corridor, Hu Chun carried a fire extinguisher, and walked forward in small broken steps, not that he was timid and afraid, after all, he was over thirty years old, rich in social experience, and calm in heart, the more at this time, the more vigilant he became, and he ran in great strides to the speed of speed, but the center of gravity of the body was also difficult to control, in case a zombie pounced out behind the door of that room, he wanted to adjust his center of gravity to meet the enemy or dodge in an instant, but it was even more difficult, but the small broken steps were different, and he could react to the zombies that appeared in any direction in the shortest possible time. Security has been greatly improved.

Sometimes, it's just in case.

Hu Chun had just walked through the door of the medical room, and the door of the medical room was suddenly pushed open!

Wang Chen followed behind Hu Chun, his nerves were always tense, and when he saw the door being pushed open, he kicked his foot, he wanted to kick the door shut, don't care if it was a zombie or something else that opened the door, kick back into the door! Hu Chun's reaction here was not slow, he heard the sound of the door behind him and paused! Twist the waist! Wheel fire extinguisher!

The two of them kicked one round at a time, and the cooperation was just right, and at the same time that the door that had just been pushed open made a muffled sound, it was instantly closed again!

There was a lot of commotion, the glass inlaid on the door couldn't help but shake so strongly, and it suddenly shattered into slag, Wang Chen didn't care that Han Li would not be injured by the broken glass, and half-squatted and dropped Han Li, who was still asleep, and pounced forward, just in time to cooperate with Li Changhuai behind him, and held the door of the medical room to death!

Anyway, the sound of closing the door just now was not small, Hu Chun no longer cared about the problem of loud gunshots, seeing his companion against the door, he dropped the fire extinguisher, and at the same time the bullet was loaded directly at the window filled with glass shards, as long as any of the heads that made a tearing moan appeared, immediately reward the other party with a peanut full of sincerity to taste!

The corridor fell silent for a moment, and after about a few seconds, a strange voice came from the medical room, "Bi, Bikai, please...... I'm still moving ......"

Although he couldn't hear what the other party was saying, he could tell that he was talking, the tense nerves of the three of them relaxed slightly, but they didn't dare to be careless, Hu Chun concentrated on holding a gun to deal with the emergency, Wang Chen simply answered: "Who are you?" Bitten? ”

"What...... Let me come out...... Success? ”

Well, it seems that this guy is just slurring his speech, and he doesn't sound like he is seriously injured, Wang Chen patted Li Changhuai on the shoulder first, signaled his companion to step back, and dragged Han Li aside, and then he slowly left the door, just like Hu Chun, pumping his gun in his hand, guarding against emergencies.

"Come out."

The door of the infirmary was pushed open for the second time, and a figure in a hospital gown cautiously poked out his hands from behind the door, signaling that he had no weapons, and then slowly moved his body out of the door.

Wang Chen saw this person's face, and he really couldn't bear to look at it directly, because this guy's appearance was too miserable, his face was full of blood, not to mention, his eyes were embedded with two panda eyes, and his grin was obviously missing a front tooth, especially his nose, which was completely flat on his face, and the layman could see that the lightest was also a comminuted fracture, and it was estimated that there was no clever repair surgery, and this nose was twisted and crooked even after it had grown, no wonder his voice sounded so strange, overall, this person was completely disfigured, and half of it must be more.

"We, we, we've just met." With a few words, the man's face twisted a few times, and it seemed that just speaking would pull the wound on his face and make it painful.

Ever seen? Or just now? After looking at it carefully, the three of them suddenly thought, isn't this Xu Dongsheng who ran over to pick up his sister after playing basketball? ! This kid looks very sunny and handsome, how did he become like this? Still here? Ah, but also, he was kicked and beaten by a sturdy girl at first, of course he would be picketed and sent to the infirmary for treatment, as for the bleeding nose...... It's definitely the end of opening the door without saying hello.

Coming together, the skin injuries that were beaten by the hump before, may not have been seriously injured by Hu and Wang with the cooperation of closing the door.

It's just that Xu Dongsheng's desire for life is obviously greater than these pains, or he also knows the truth that more people can escape, and he didn't say half a nonsense, but forced a distorted smile on his injured and terrifying face, trying to please the few people in front of him, hoping to take him to escape together.

In the end, he is still young, and he can't even act, if Xu Dongsheng is irritable and scolding or simply angry at the moment, Wang Chen and the three of them are likely to apologize and accept Xu Dongsheng's joining, because they will have such a reaction after being injured, but Xu Dongsheng smiled like this, which suddenly made people look down on him.

Of course, you can also say that Xu Dongsheng was afraid that the other party would be angry and give him a shot, so he swallowed his anger and made compromises, but Han Li was half-lying and asleep next to him, which has already shown that these three are not the kind of people who are selfish and narrow-minded, so no matter what aspect it is, Xu Dongsheng can be regarded as exposing his greedy nature and fear of death, and he will definitely be unreliable in a critical moment.

Wang Chen hesitated a little, glanced at Hu Chun, Hu Chun also felt that this kid was unreliable, but he didn't want to force him to make any moves, and then cause unnecessary trouble, so he simply took out the set of hypocrisy commonly used by people in society, put away the pistol, and said politely: "Oh, oops, Brother Xu, I'm sorry, I'm really embarrassed, how about it, the injury is not serious, Brother Hu, I will bandage it, and give you a simple treatment of the wound?" ”

"It's okay, first, get out." Xu Dongsheng was obviously relieved when he saw that the other party accepted him, no matter whether it was right or wrong at the moment of life and death, his brain would always turn faster, and he turned around and turned around in the medical room.

When Xu Dongsheng turned around, Wang Chen had already made a disgusted and greasy expression for Hu Chun, and Hu Chun couldn't help it, so he spread his hands, returned a helpless action, and reminded the two companions with his mouth, 'Beware.' Only Li Changhuai was left in the circle next to him, and he didn't know what kind of dumb riddle these two were playing, but he still knew that he couldn't talk much at this time, so he nodded to indicate that he knew and chose to shut up.

After the three of them finished communicating, Xu Dongsheng had already turned out a medical bag and patted it, "Early, ready, okay, it's all for treatment." ”

"Cheng, Brother Xu is bothered, oops, don't talk too much if you're seriously injured." Hu Chun was polite, but the pistol was confiscated, and the muzzle of the gun was pointed at the picket office next to the medical room, and Xu Dongsheng asked: "Since the accident, has there been any noise in the picket office?" ”

Xu Dongsheng shook his head, "The alarm sounded, and they all ran out." ”

Leaving Li Changhuai in the corridor to watch the wind, Wang Chen and Hu Chun probed into the picket office, the temporary office is actually nothing too eye-catching, it is a suite, the inner room is a bunk bed for resting with a small bathroom, the outhouse is placed as a desk computer desk, along the wall there are rows of chargers, plugged in the charging walkie-talkie.

I searched the whole house, and only found a satellite phone, and there was not a single hair in the expected weapons and equipment and even car keys.

To say that the two are not disappointed is false.

Can't blame them for their misjudgment, they are all ordinary people, and the number of times they go to the front desk of the police station is limited, even if Hu Chun knows a lot of classmates who are policemen, it is impossible to find out that military and police facilities generally have an equipment room dedicated to storing equipment, even if Hu Chun thinks of this in a flash of inspiration now, a huge sanatorium, wandering zombies everywhere, where do you let them go to find Cao Baoquan These places where the guards and pickets temporarily store equipment?

Holding the satellite phone, Wang Chenxiang held the last straw, he didn't know if the number he used to call for help was still valid, instead of rushing out to be caught and eaten by zombies, it was better to hang up the phone and call for off-site assistance, maybe satellite remote sensing could point them a way out?

The call seemed so long at this moment.

When the familiar voice of No. 3148 came from the satellite phone, which was slightly hoarse and somewhat intermittent, not to mention Wang Chen, Hu Chun, who came to the satellite phone, couldn't help but have red eyes.

The news of the loss of contact with the nursing home must have spread all over the rescue center as soon as possible, and since it will take time for the satellite to be converted, the only thing that can be done now is to mobilize the army and epidemic prevention personnel in the town to block the intersection at the foot of the mountain and wait and see what happens. At this moment, No. 3148 suddenly received a call from Wang Chen, learning that there were survivors in the sanatorium, and her excitement can be imagined.

Naturally, the dialogue between the two sides was projected on the public channel of the rescue center at the first time, and it was synchronously output on the computer of the head of the military region, if it were not for the scruples of the mentality of these civilians who could no longer suffer unnecessary stimulation, it would not be the operator No. 3184 who would be talking to them now, but the head of the military region himself!

“…… According to our observations, those strange birds are all dead, we are in Captain Cao's office, we can't find Captain Cao, and it is estimated that there are no living people in the sanatorium, oh, except for the four of us, no, five. Wang Chen's description is a bit upside down, this can't be blamed on him, the experience of fighting for his life from Harbin has increased Wang Chen's psychological endurance, so that he can say some complete words, if he is just changed to an ordinary person who has not experienced the zombie slaughter to describe it, whether he can jump out of the complete vocabulary is a question.

"The satellite still has fifteen minutes to be in place, so you should ensure your own safety as much as possible, understand?" The operator of No. 3148 looked at the instructions handed over by the team leader, and was a little puzzled, the satellite had just completed the orbit transition, and remote sensing could be used at any time to guide the survivors to escape, why did they tell the survivors to wait for another fifteen minutes? At this time, one more minute is more dangerous!

No. 3148 does not know, and neither do Wang Chen and other survivors, at this moment, the head of the military region is facing a choice that is critical to the lives of the survivors.
