Everyone in the vaccine laboratory was staring at Yu Yong and Academician Zhong in the isolation ward, even the soldiers in charge of the guards, because all the people present had been injected with vaccines, and if the vaccine was harmful to zombies, God knows what kind of adverse reactions it would cause in them.

At this moment, there was a sudden explosion, and a sewer in the laboratory exploded violently, and a thin figure came out of the smoke of gunpowder, fired several shots in succession, knocked down the three soldiers, pounced on Academician Zhong's side, and put the muzzle of the gun on his forehead: "No one is allowed to move!" ”

It was Ling Shanshan who blew a way out of the sewers!

She finally received the news from "my father" through brain waves, through a series of attacks by commanding the zombie army, "he" finally greatly weakened the power of the homeland, creating a favorable opportunity for Ling Shanshan to infiltrate the vaccine laboratory, Ling Shanshan obtained the vaccine easily, but it was difficult to bring it out of the homeland, only by striking hard at the living force of the homeland, so that they had no time to take care of it, Ling Shanshan had a chance to get the vaccine and bring it out.

After Ling Shanshan hijacked Academician Zhong in her hand, while jamming his neck, she pointed a gun at other expert nurses, preventing them from acting rashly, and retreated step by step to the safe where the vaccine mother was placed, "Open the door!" ”

Academician Zhong instantly understood: "Originally, the target of your intelligent corpse was the biochemical virus mother? Yes, you are very smart, this female parent has the most complete biochemical virus genes, you must want to use it to evolve, right? ”

Ling Shanshan knocked on Academician Zhong's head with a pistol, and the heavy handle of the gun immediately knocked a wound on the old man's forehead. A stream of blood flowed out: "Open the door honestly, it's none of your business." ”

Academician Zhong shook his head: "I won't open the door, now you are terrible enough, the damage to mankind is big enough, I will not boost your strength anymore." ”

Bang, Ling Shanshan raised her hand and killed an expert: "If you don't open the door, I will keep killing people." ”

Academician Zhong hesitated for a moment, snapped, and Ling Shanshan fired another shot. Another expert threw himself at the feet of Academician Zhong. A trail of blood flowed from beneath him: "I don't have much time, but it's enough to kill everyone in this room!" ”

Academician Zhong slowly stretched out his hand and pressed the combination lock on the incubator, the box. Slowly opened. A mist of cold air spreads out of the incubator.

Ling Shanshan saw it at a glance. At the top of the incubator, two test tubes are placed side by side, one of which is colorless and transparent. One is light blue, she has inquired a long time ago, the light blue one is the biochemical virus vaccine, and the colorless and transparent one is the mother of the biochemical virus.

Ling Shanshan stretched out her hand and held the colorless transparent test tube in her hand, and then--then she made a very strange movement, like a bullied little girl, and suddenly her hands tightly hugged her head.

Academician Zhong was stunned, he didn't know what this handsome but actually ruthless smart corpse was doing, he once wanted to subdue the motionless Ling Shanshan, but thinking that with the strong physical strength of the smart corpse, he was an old guy who was not an opponent at all, and he still didn't dare to make a move after all.

Captain Sun kept staring at Ling Shanshan, but he was covered in torture equipment, and he was so far away that he couldn't move at all.

Ling Shanshan maintained such a strange posture for two minutes, during which time there was a lot of gunfire outside the laboratory, although there were many experts and medical staff in the laboratory, they were all bare-handed, and the sharpest weapon was just a scalpel, this thing couldn't kill a gun-wielding smart corpse, so although she saw Ling Shanshan's strange appearance, she didn't rush up.

Captain Sun finally confirmed that Ling Shanshan was not on alert, but that his body was in an inexplicable condition, and he quickly walked over to several soldiers who had fallen to the ground, intending to get the keys to them and open his handcuffs.

Ling Shanshan moved suddenly, only to see her straighten up, open the stopper of the test tube, tilt her neck, and pour all the biochemical virus mothers in the test tube into her mouth.

Academician Zhong looked at this scene, his heart tightened, sure enough, the intelligent corpses were aimed at the biochemical virus mother, and they needed to be highly purified by their own hands to get the evolution, damn it, they became abusers.

Smack, Ling Shanshan threw the empty test tube to the ground, and looked up at the outside of the home where the artillery was blazing: "'My father', you didn't expect it, right?" My brainwave shielding ability is far beyond your expectations, and you think you have complete control over me, but in fact I am deliberately showing weakness so that you can send me into your home to obtain the mother of the biochemical virus. I'm not an idiot, if I bring you the bioviral mother and you get a more powerful evolution, I'll be your slave for the rest of my life. But now, the most perfect gene of the biochemical virus you dreamed of has become a part of me, and soon, I will be even stronger than you, and I will gain true freedom. ”

Academician Zhong's mind was full of thoughts in an instant, and he had already vaguely understood the inside story hidden behind Ling Shanshan's words, it seemed that there were also many contradictions inside the Zhi corpse that attacked the homeland, perhaps, he could use this to protect the people in the laboratory. He stepped forward and said loudly, "Ling Shanshan, this biochemical virus mother is not perfect......

Ling Shanshan snorted: "Stop." Old man Zhong, you are a good person, don't force me to kill you. ”

Academician Zhong said: "Listen to me, Ling Shanshan, there is a problem with the biochemical virus gene I purified, it is not perfect, and the vaccine we produced is also imperfect, if you want to use this biochemical virus mother to fight against the powerful intelligent corpse that controls you, it is very likely that you will be disappointed......"

Ling Shanshan was just about to say something, when Yu Yong in the isolation room suddenly shouted, "Blood! Blood! My whole body is bleeding! Old man Zhong, there is really a problem with your vaccine! Dead, dead, really going to die! ”

Academician Zhong ignored Ling Shanshan's muzzle and pointed at himself, rushed into the isolation room, and saw at a glance that Yu Yong's mouth and nose were also like the deputy director zombie just now, and a large amount of blood began to bubble out.

Yu Yong coughed and scolded: "Fuck, fuck, I knew I was better as a smart corpse, it's really, really fucking not worth it." He stretched out his hand to Academician Zhong: "Old man Zhong, you, you really killed me...... We must develop a real vaccine. I—I don't want my wife and children to die at the hands of your fake vaccine......"

Yu Yong's capillaries all over his body began to ooze beads of blood, and suddenly, he convulsed, stood still, and the electrocardiogram became a straight line.

Ling Shanshan had already rushed to Academician Zhong's side at this time, and witnessed all this with her own eyes, on the hospital bed in the isolation room, one was obviously a zombie, and the other had just died, it should be a Zhi corpse. "What the fuck is going on?" Ling Shanshan pointed the head of the academician at the clock with a gun.

Academician Zhong looked at Yu Yong's body in frustration: "Both of them have been injected with the vaccine I developed. But--you see. The vaccine had major flaws, and everything was fine in the early days, but -- but, alas. You've also seen what happened to the zombies after the vaccination. Without exception. It's all death. ”

Ling Shanshan still didn't understand the situation she was in: "If the vaccine is defective, it means that the mother of the biochemical virus is defective...... The so-called perfect biochemical virus gene is not perfect. It is even possible that it is fatal ......"

Ling Shanshan raised her hand and snapped a shot, hitting Academician Zhong in the abdomen: "Old man Zhong, you killed me, go and die." ”

At this moment, a figure pounced on Ling Shanshan with a roar, a hand knife shot down the gun in Ling Shanshan's hand, Ling Shanshan did a backflip, quickly flashed the opponent's jerked legs, and quickly flashed to the wall - it was Captain Sun who shot at Ling Shanshan, and while he took advantage of a series of drastic changes to disrupt Ling Shanshan's attention, he found the key from the soldier's corpse and opened the handcuff.

After forcing Ling Shanshan back, Captain Sun didn't make any more moves, he said quietly: "Come quickly, treat Academician Zhong's injuries." ”

Several doctors immediately rushed up and wanted to operate on Academician Zhong to get bullets, but Academician Zhong raised his hand to stop them: "It's useless, we will all die." He raised his head and said to Captain Sun: "Everyone in the homeland will die, the vaccine I developed has major defects, the zombie intelligent corpse will die if it is injected, and we humans will also be injected, there will definitely be problems......" He turned his head to look outside the laboratory: "Commander Xia Zhen and the soldiers have all been injected with the vaccine......"

In fact, on the White Wall Line, anomalies have already appeared.

Originally, everything was going well, although the zombie army attacked in the open and ground, but the heroic homeland soldiers still held on, thanks to the vaccine bullets, as long as a vaccine bullet hit one of the zombies in the tunnel, it would cause a chain reaction, resulting in a group of zombies being wiped out. The soldiers defended with ease, and even sent some of their men to the white wall again.

A soldier operating a heavy machine gun became more and more excited, and he shouted: "One, another, another one, ha, buddy, do you see, I used a heavy machine gun to shoot the effect of point fire, 1000 meters away, a bullet explodes the head of a zombie, damn, have you ever seen such a great shooting level?" Ha ha. ”

The comrade-in-arms next to him was bombarding the zombie group with a mortar, and he also said happily: "Yours, boy, but my artillery accuracy today is also very high, I don't know why, I think I have a lot of physical strength today, and I don't have to think much about manipulating this mortar to calculate the target parameters, and the data will automatically jump out of my head." ”

The heavy machine gunner fired another point shot, and was satisfied to see a zombie's head bloom: "That's it, I also think that I am in a very good state today, and I have endless energy all over my body......" He turned his head: "Actually, we should suggest that Commander Xia not necessarily stick to his homeland, send an armored detachment, surprise attack behind enemy lines, and defeat the behind-the-scenes commander of the zombie army in order to completely turn the tables......"

The heavy machine gunner saw his mortar comrades looking at him with wide eyes, his mouth half open, and a look of surprise, he shrugged his shoulders: "Why, you don't agree with me - of course, I know that Commander Xia wants to defend the vaccine with all his might, but it's really embarrassing to fight like this......" He felt that the skin on his face was a little itchy, and he stretched out his hand to scratch it, but there was a sticky feeling on his fingers, and the heavy machine gunner raised his hand to look in front of him, but saw a wisp of bloody flesh hanging on his fingertips!

The mortar man took a few steps backwards, and as soon as he saw that the skin on the heavy machine gunner's face suddenly burst open, like a piece of torn paper, and under the torn skin, there were bloody muscles!

"What's going on?" The Heavy asked again stupidly, and reached out again to scratch his face, at which point his whole body suddenly swelled up like a balloon that had been inflated. When the shattered uniform fell to the ground, the heavy machine gunner had mutated into a kind of monster - naked all over his body, his skin was all bursting open, and the muscle groups inside developed abnormally in a very short time, and the whole person became a skinless muscle monster, its eyeballs were spinning in the sockets with only muscles, staring at the mortar who had drawn his pistol and was trembling and pointing at him.

Pop, a pistol of mortarmen's pistol emitted a puff of green smoke, and the bullets flew towards the head of the muscular monster that was close at hand. However. The muscle monster moved faster, and with a flick of its head, it dodged the bullet with an initial velocity of 318 meters per second and leaped. He threw down his comrades. With a wave of the hand. With a snap, the mortar man's head was flattened alive!

This scene made the soldiers next to him look at it with tears in their eyes. Countless muzzles turned around and shot at the muscular monster, but the monster was extremely nimble, jumping high and low on the white wall, and not a single bullet hit its head, and although it was shot a few times in the body, it did not hinder its ghostly swiftness at all.

"Vaccine bullets! Hurry up with the vaccine bullet! This is a new type of zombie! A soldier roared, quickly stuffed a vaccine bullet into the chamber of the gun, and under the suppressive shooting of his comrades, a shot hit the body of the muscle zombie, however, the vaccine bullet with the original magical effect was completely ineffective against the muscle zombie!

Unwilling, the soldier stuffed a vaccine bullet into the chamber of the gun again, and shouted to his comrades beside him: "Cover me!" However, he saw that the soldiers around him couldn't help but take a few steps back, and the muzzle of the gun in his hand was still aimed at him, and he asked inexplicably, "What are you doing?" But he felt an itch on his hand, and when he looked down, he saw the skin on the back of his hand silently bursting open, and his muscles were expanding wildly......

On the white wall, one after another warriors turned into muscle zombies, and they, without exception, were the first group of fighters to be vaccinated!

Vaccines, instead of saving humanity, have created a whole new zombie population!

Commander Xia Zhen was directing the battle at the mouth of the tunnel, and the injured forehead had been temporarily sewn up, because the fighting inside and outside the white wall was in full swing, and the explosions were one after another, she did not notice the sound of Ling Shanshan blowing up the ditch and shooting the soldiers in the vaccine laboratory, at this time she was giving an order to a soldier: "Notify the ammunition production workshop, and bring another batch of vaccine ammunition, as many as you want!" ”

The soldier hesitated for a moment: "Commander Xia, Academician Zhong of the vaccine laboratory has stopped vaccine production for a while, and they are also waiting for rice to be put into the pot in the ammunition production workshop, no matter how much I urge, it is useless." ”

Commander Xia Zhen's face was a little unpleasant: "Did Academician Zhong say something like that the vaccine may be unstable and may be defective?" Alas, when is this coming, I can't withstand the next wave of attacks from zombies, and even the entire homeland will be lost, Academician Zhong ......"

At this moment, a violent gunfire suddenly came from the white wall, and the billowing smoke from the explosion rose high on the wall, and Commander Xia Zhen was stunned: "What happened on the wall?" Is it another wave of attacks from the Zombie Air Force? ”

Just when everyone was suspicious, a soldier stumbled down the stairs: "Run! Come on! Monster! Such powerful monsters, too fast, they are too fast, we can't beat them...... Vaccine...... Yes! ”

The warrior screamed in misery, only to see a bloody hand come out of his chest, and the big bare muscular hand held the warrior's heart!

Tom tom, almost subconsciously, the soldiers guarding around the tunnel shot fiercely at the stairs, which were mixed with vaccine bullets, anti-aircraft machine gun bullets, the soldier who had been knocked out of the heart was almost cut into several pieces, however, behind the soldier's tattered body, a shadow suddenly jumped high, this jump was actually 5 or 6 meters high, more than 10 meters away.

I saw that the muscular monster that had swooped down from the stairs easily avoided the fire and leaped into the middle of the warriors, its palms dancing rapidly, its sharp claws faster than the sharpest knives, and the flesh and blood of the warriors flew everywhere it passed. One of the fighters crossed the Bayi bar and tried to block the palms of the muscle monster, but he didn't expect that the barrel made of high-strength steel tubes would be cut into two smooth sections by one palm under the palm of the muscle monster, like a wooden stick meeting a steel knife!

The muscular monster who cut off the barrel of the Bayi bar stretched out his arm, grabbed the soldier's head in the palm of his hand that had become the size of a fan because the muscles had swelled several times, and with a slight pinch, the warrior's head exploded like a red pestle!

Knock knock, several black grenades flew over and exploded around the muscle monster, the flying shrapnel knocked the warrior next to him to the ground, the smoke cleared, the muscle monster half knelt on the ground, raised his hands and crossed to protect his head, all parts of his body were injured by shrapnel from the grenade, his muscles were broken, and a large stream of black liquid flowed out, however, it was not dead, when it lowered its arms, its head was still intact.

Commander Xia Zhen, who was kneeling behind the grenade launcher, was dumbfounded: "This, where did this monster come from?!" ”

No one could tell her the answer, and in a series of screams, more similar muscle monsters jumped down from the white wall, their bodies were naked with red and abnormally swollen muscles, their movements were extremely fast, and their strength was so great that they could smash people's heads with one palm, and suddenly set off a bloody storm among the elite warriors of the homeland!

The first to appear, the muscle monster that was attacked by Commander Xia Zhen with a grenade targeted Commander Xia Zhen, it half-crouched down, jumped suddenly, and rushed straight to Commander Xia Zhen's volley, Commander Xia Zhen couldn't avoid it, seeing that the giant palm with bulging muscles was about to hit his head - bang, with a bang, the already broken glass of the vaccine laboratory was knocked open from the inside, and a figure pounced out, roared, and hit the muscle monster, knocking the muscle monster out sideways. (To be continued......)
