The three of them fled into a small commercial and residential building, Cao Yin was unable to stand due to a broken lower leg, so he could only lie on the floor on the first floor in embarrassment, his head was dizzy, he didn't know what to say, and the other two young men also slumped against a counter with a blank face, panting while looking at Cao Yin.

There was another loud roar in the street outside, and the entire building where Cao Yin was located was shaken, and Cao Yin guessed that it must have been the people in the helicopter who fired another rocket at the ground, and their purpose was to destroy the monster they had unleashed.

After a while, the sound of the helicopter flying outside became quieter and quieter, and one of the two men who was with Cao Yin came to the door with a cat, looked outside, and said with a sigh of relief: "The helicopter has flown away, probably fine." ”

"Where's the big zombie?"

"I was hit by two rockets, and I was bombarded by the Grimm machine for so long, I don't believe that monster is still alive," looking out was a young man with handsome and clear facial features and bright eyes, he turned around and said, "Rhubarb, how is this kid?" ”

"He shouldn't be able to die, but it looks like his leg is seriously injured, you see that he can't stand up now, Xiao Beichen, don't you understand people, call me Huang Lin!" Huang Lin is also a young man of the same age as Cao Yin, he has dark skin, a thin body, and relatively small eyes.

"Okay, okay," Xiao Beichen grinned and said, "I also think that the name rhubarb is more cordial." ”

"Fuck off, I'm not familiar with you!" Huang Lin complained, "Xiao Beichen, aren't you a doctor, come and see if his injuries are serious!" ”

Xiao Beichen moved to Cao Yin's side, checked the injuries on Cao Yin's body, and asked: "Brother, looking at your performance on the street just now, it doesn't seem to be an ordinary person, your left leg has two fractures, and your back seems to have been scratched by that monster, but the strange thing is that there is no bleeding, how do you feel now?" ”

"I feel very uncomfortable, dizzy and want to vomit," Cao Yin put his head on his arm and said in a weak tone, "I'm dying of thirst, I want to drink water......"

"There's no water here," Huang Lin said, "We want to drink water too!" ”

"What's your name?" Xiao Beichen asked.

"My name is Cao Yin," Cao Yin said weakly, "Who are you?" ”

"We are survivors of Jianghua City," Xiao Beichen rolled Cao Yin's eyelids and said, "You must also be a survivor, so if you don't die, you can be considered unlucky enough to encounter today's incident." ”

"Cao Yin, do you know the Black Building?" Huang Lin asked, "We want to take refuge in the Black Building, it is said that they are the largest survivor organization in Jianghua City, and joining them will definitely increase the survival rate." ”

"It turns out that you are also looking for it," Cao Yin said, "Among the two groups of people who planned to grab the airdrop just now, there is probably a group of people who are from the Black Building." ”

"How do you know?" Huang Lin asked.

"Jianghua City can now hold so many guns, there are only two black buildings and heavy rain, heavy rain was originally a gang remnant, it is not surprising that there are guns and ammunition, and the black building is supported by a powerful person in secret," Xiao Beichen said, "It seems that this old man also knows some information about the black building." ”

"That's right, I also know the two strongholds of the Black Building," Cao Yin said, "I'm so thirsty, can you help me find some water?" ”

"This guy is planning to trade with us with this information," Huang Lin said unhappily, "Do you have a conscience, we just risked being killed by a machine gun to save you!" ”

"In this commercial and residential building, if you are lucky, there should be some resources that have not been looted, but there is no guarantee," Xiao Beichen looked useless and said, "Rhubarb, you go with me to find it, it just so happens that we also need to replenish it, people want to beg for saliva to drink, you don't need to be so careful." ”

"Okay, just leave him here?" Huang Lin said stupidly.

"Of course, are you looking for him behind his back?" Xiao Beichen said, "Let's go, be careful of the zombies in the building, let's take it lightly." ”

"I ...... I'm still here to guard this dude, you...... Let's go ourselves, we'll wait here...... Waiting for you. Huang Lin swallowed his saliva and spit out.

Xiao Beichen said: "I'm kidding you, there is a high probability that there are no zombies in this building, and even if there are, they will come out a long time ago." ”

"How do you know?"

"You see the artillery fire outside just now, the sound is so loud, aren't all zombies very sensitive to sound, if there is, they will definitely move towards the sound source, but we have been here for so long and have not seen a single zombie run out."

Huang Lin pondered for a moment and said, "Okay, don't fool me, what if there are still zombies in this building?" ”

"You're so smart, I can still deceive you, even if there are zombies in this building, it must be a minority, let's find two sticks here to deal with it," Xiao Beichen said with a smile, "This old man looks like he's dying of thirst, let's quickly find him some water." ”

"Yes, his face is purple," Huang Lin said, "What's wrong with him, he didn't see blood, why does he look so weak?" ”

"It may be a little hypoxic," Xiao Beichen observed Cao Yin's complexion and read, "Maybe his heart and blood function is not very good, I don't know the specific reason, brother, what else is uncomfortable with you now besides dizziness?" ”

"Tinnitus and dizziness, weakness in the limbs, chest tightness and shortness of breath," Cao Yin said in a weak voice, "Recently, these symptoms have become more and more frequent, and it seems that I will not live long, hehe." ”

"Is it possible that you were scratched by that monster's claws and infected with the zombie virus?" When Huang Lin said this, his eyes became frightened, and he hurriedly distanced himself from Cao Yin.

"The guy infected by the zombie doesn't have these symptoms, and even the corpse doesn't change so quickly," Xiao Beichen patted Cao Yin's face and said, "Brother, look at your face is so ugly, your lips are purple, do you have a heart attack, have you seen a doctor before?" ”

"I saw it, the doctor said that I was a hereditary blood disease, not contagious, and the doctor diagnosed that it was a lack of oxygen caused by insufficient oxygen supply to red blood cells, and I knew about gas poisoning, right?" Cao Yin smiled bitterly, "I produce a toxin in my body, and the toxicology of this toxin is similar to that of carbon monoxide. ”

"That's not it, the affinity between red blood cells and toxins is better than that of oxygen, so it will be so difficult to supply oxygen to organs and tissues throughout the body," Xiao Beichen glanced at Huang Lin and said, "The more concentrated the toxins in this little brother's body, the more difficult it will be to supply oxygen, and the weaker his body will be. ”

"It's so pitiful," Huang Lin shook his head and said, "I saw that he was running and flying just now, and I thought he was a master of light skills, but I didn't expect him to be a sick man." ”

"My teacher used to have a patient, and the situation was exactly the same as his," Xiao Beichen clasped his hands to his chest and muttered, "It is also the lack of oxygen supply caused by the self-generated toxins in the body, and the teacher provided her with a special injection to relieve the symptoms of hypoxia, and the effect is quite good." ”

Cao Yin's eyes lit up, and he hurriedly raised his neck and asked, "Which hospital is your teacher from?" Where is he now? Did that girl get cured later? ”

"My teacher disappeared two years ago, and he has not been found," Xiao Beichen said, "When my teacher was still there, that girl gave up treatment for some reason, and I don't know if she is still alive." ”

"Can the injections you are talking about relieve the symptoms of hypoxia?" Cao Yin continued to ask, as if he saw a glimmer of hope.

"Well, it is said to be a nano-scale oxygen sustained-release agent, which can enhance the oxygen concentration in the blood, so as to alleviate the lack of oxygen supply to red blood cells," Xiao Beichen said, "You don't want to find this injection, right?" ”

"Yes, I want to!" Cao Yin said, "Which hospital is it?" ”

"Emperor Shadow Medical Department," Xiao Beichen said, "Uh, it is estimated that it is also deserted now, how can there still be a stock of this sustained-release agent." ”

Xiao Beichen's answer was like a bolt from the blue to Cao Yin, Cao Yin forced himself to calm down, and said, "You are from the Imperial Shadow Medical Department?" ”

"Uh, sort of, it's just an intern," Xiao Beichen said, "I just graduated from college and encountered the zombie plague, and I studied clinical medicine for seven or eight years, and I wanted to open a clinic in this city, alas, ......"

"That's not it, I just encountered this kind of natural and man-made disaster just a few years after I went to college," Huang Lin said, "It's really unlucky, I knew that I didn't work so hard in high school!" ”

"Who is your teacher?"

"You don't know," Xiao Beichen said, "and he's been missing for so long, do you still want to find him?" ”

"Just tell me," Cao Yin sat up and looked at Xiao Beichen with a serious expression.

"His surname is Lin, his name is Lin Yaozhen," Xiao Beichen said, "He is the ace physician of the hematology department of Diying Medical, and he has led the development of many special drugs for the treatment of blood diseases, and this oxygen sustained-release agent is also one of his masterpieces." ”

Lin Yaozhen ...... I haven't heard of it," Cao Yin said, "If what you said is true, I just want to find the kind of sustained-release agent he developed, and my symptoms of hypoxia must not be delayed for too long." ”

"I don't think you should hold on to this kind of illusory hope," Xiao Beichen sighed and said, "The development and production cost of this sustained-release agent is particularly high, and there is no mass production in the first place, that girl is a wealthy daughter, so she can afford this expense, and after the outbreak of the zombie plague, the Diying Medical Department must have withdrawn from Jianghua City, and it is impossible for these important resources to remain in Jianghua City." ”

"No, you don't understand," Cao Yin showed a bleak smile, "I think it's very likely to be found." ”

"Then try your luck at the Imperial Shadow Medical Department after your body recovers," Xiao Beichen said, "Huang Lin and I will go find something to eat and drink first, and you will stay here and wait for us to come back." ”

Xiao Beichen and Huang Lin walked towards the staircase, and after Cao Yin confirmed that they had gone upstairs, he took out a SZK-2 orange standard injection from his backpack, according to Lin Xinran, this numbered reagent is a healing elixir for the awakened, and only one injection can speed up the healing of external injuries.

"I don't know if the fracture can be cured...... Cao Yin said secretly, he used a syringe to pull out the SZK injection, and then pierced it into the thigh, with the injection of the liquid medicine, Cao Yin clearly felt that there was a warm and moist force flowing towards the wound on his body.

"By the way, doesn't the fracture have to be reduced and orthopedic first," Cao Yin suddenly thought of this, if the misaligned bone position is not corrected and fixed first, then even if the bone grows well, it will be deformed!

"Xiao ...... Dr. Xiao! Cao Yin glanced at the corridor, it was pitch black, and no one was there, "When that Xiao Beichen comes back to help me straighten my bones, it shouldn't heal so quickly, right?" ”

"Hmm......" Cao Yin suddenly felt something slowly squirming at the fracture of his left leg, and several large bags the size of eggs bulged out on his skin.

", parasite?" Cao Yin was so frightened that he pulled out his knife and slashed it at the bulging leg area, only to see a cloud of dark red blood gushing out of the cut and turning into the head of a red butterfly.

"What about you paddling Nima?" Red Butterfly glared at Cao Yin and said angrily, "I was planning to help you reset your bones, don't move!" ”

"Yuan, it turned out to be you......" Cao Yin smiled embarrassedly, "There are many bags bulging on my legs, which scared me into a cold sweat." ”

"The injection you just injected strengthens the self-healing function of the blood deformity," Red Butterfly said, "and the blood of the Shadow is all over your body, so it can help you repair all the injuries that have accumulated before, including those two gunshot wounds on your heart." ”

"Awesome......" Cao Yin said, "How did you reset the fracture?" ”

"The most powerful thing about the blood of the skeleton is that it reads memories," Red Butterfly said, "whether it is the memory of the brain, the memory of the muscles, or even the memory of the bone cells, it can be read and used, so it is not difficult to reset your own misaligned bones, but the more complex it is to repair the damaged tissue, the greater the amount of energy required." ”

"Energy?"

"That's right, you can use the injection you just took as a boost to the Shadow Blood," Red Butterfly said, "instead of consuming your own energy, the energy to heal the wounds is beyond your current state." ”

"So, I don't have to find someone to straighten my bones?"

"No, I'll help you with this level of injury, provided you get the kind of injection you just had." After the red butterfly finished speaking, she burrowed into the wound and continued to reset the bone.

Cao Yin could see with the naked eye that his slightly bent left calf was returning to its original shape at a very slow speed under the squirming of the blood bulge under the skin, and his inner feelings at this time could only be described as incredible.
