"What's going on?" I rubbed Long Hao's shoulder, "They said the situation is not optimistic? ”

"I don't know." Long Hao stared intently at the busy medical researchers in the isolation ward, as well as Huang Weizheng, who was lying on the hospital bed and wearing a ventilator oxygen mask.

It was almost evening outside, and Long Hao and Liang Minxuan had been in this cold underground third floor for almost a day. I found them after leaving Zhang Xing's office the day before yesterday. In the days we left Wanxiang City, they had a pretty good life, at least they didn't have to worry about their lives. But at this time, looking at Huang Weizheng in the ward, even Liang Minxuan, who was arrogant to me on weekdays, was full of sadness, and he was cautious when he spoke, for fear of affecting Huang Weizheng's treatment.

"Just now Dr. Lu said that Brother Niu's high fever can't go away, and now they are still trying to figure out a way." Long Hao saw that his lack of a word would only make me more anxious, so he still talked about what he knew.

"Is it a problem with the vaccine?"

"It's not...... Bar...... I don't know. ”

"Lu Huaxiong said that the vaccine is fine, do you believe it?" Liang Minxuan handed Long Hao a glass of water, looked at the ward suspiciously, and asked me.

"Dr. Lu should be a good man...... That's all I can say. "I looked at Lu Huaxiong, who was trying to find a way to cool down Huang Weizheng, he was so anxious now, it couldn't be that he was acting for me on purpose.

Lu Huaxiong just glanced outside and saw me standing outside the isolation room, so he pressed the call button on the microphone and said to us: "Now that the temperature can't go down, we really can't do anything." ”

"How so? Isn't it okay the day before yesterday, yesterday, even this morning? Liang Minxuan asked excitedly, "Is there a problem with your medicine?" ”

Lu Huaxiong shook his head helplessly, sighed, and leaned on the edge of the table tiredly. "The vaccine is absolutely effective. It's just that we haven't conducted clinical human experiments before, so we don't know what side effects it will have on people. ”

"So fever is a side effect of this medicine?"

"It should be that the fever indicates that his body's immune system is working violently, which may be due to the virus in his body or an overdose...... In short, there are still many uncertainties. ”

"How do you feel that you don't know anything, so you take Huang Weizheng as an experiment?" Liang Minxuan reprimanded impatiently, and Lu Huaxiong could only nod awkwardly.

Chen Mo, Wei Hong, and Wu Fei also came over, and as soon as they came, they asked about Huang Weizheng's condition again, and Lu Huaxiong patiently explained to them again. Compared with Liang Minxuan, who speaks straightforwardly, other people's attitudes towards Lu Huaxiong are also quite gentle; They were surprised by my calm reaction, and perhaps in their eyes, I should have looked like an ant on a hot pan by now. But maybe it's because I've experienced this kind of torture by the mutant virus, and it's also because Lu Huaxiong helped me get out of this broken underground laboratory, so I still have some respect for him.

After listening to Lu Huaxiong's explanation, Chen Mo lowered his head and pondered for a while, and suddenly shouted excitedly: "Could it be that because Du Yuheng and Huang Weizheng's blood types are different, the vaccine you developed with Du Yuheng's blood will react to Huang Weizheng?" ”

Everyone was taken aback by Chen Mo, although I didn't know what she wanted to say, but I felt that maybe there was some truth in her words, but Lu Huaxiong just smiled and said, "Girl, you want to talk about agglutination reaction, right?" That was the state of blood transfusion, we only extracted Du Yuheng's blood but did not use his blood to directly transfuse Huang Weizheng......"

"That's what kind of rejection reaction!" Chen Mo still didn't give up, and shouted out a term that I seemed to have heard, although I didn't know what was going on.

"That's an organ transplant." Wu Fei pushed Chen Mo with tears and laughter.

"Yes, rejection is the entry of allogeneic tissue into an immunocompetent host...... Lu Huaxiong's words came to an abrupt end, he whispered something thoughtfully, and immediately turned around and shouted, "I know!" ”

People inside and outside the isolation room looked at Lu Huaxiong in confusion. Lu Huaxiong even forgot to turn off the microphone and said excitedly to his colleagues and assistants: "It's autoimmunity!" ”

As soon as they heard the words "autoimmunity", the eyes of the people with medical knowledge suddenly lit up, and their faces even showed a smile of relief. Those of us whose concept of medicine is almost limited to treating fevers and colds can only watch the scientists in the isolation room discuss with each other questions that we don't understand at all.

"Uh...... What the hell is going on? Chen Mo didn't know whether to interrupt the discussion of the experts, but out of concern for Huang Weizheng, she still picked up the microphone and asked.

"Du Yuheng's body is the original modified HTS89 virus, not his own antibodies. The reason why the virus he contracted after the zombie bite was safe was because the dominance of the original virus devoured the foreign zombie virus. Lu Huaxiong smiled happily and said, "We have isolated the gene segment that can inhibit the phagocytosis of foreign viruses according to Du Yuheng's serum, and removed the gene segment with potential mutation threat, but our vaccine still retains Du Yuheng's immune gene." ”

"So ......"

Therefore, because the antibody of Du Yuheng's gene contains some antibody cells that he has been immune to before but not for Huang Weizheng, this leads to autoimmunity. To put it bluntly, Huang Weizheng's immune system is attacking the normal cells in his body. ”

As for Lu Huaxiong's complex teaching explanations, we are actually only half-understood. Wei Hong simply asked bluntly, "Then what are you going to do now?" ”

"We just need to rewrite the vaccine to cover up Du Yuheng's genes and let it fool Huang Weizheng's body's immune system......"

Before Lu Huaxiong could finish his sentence, a young man behind him interrupted him and said, "Wait, doctor, we have no time to find the contradictory part of the immune genes of the two people......

"We don't." Lu Huaxiong said categorically, "We only need to activate the original virus serum." ”

Lu Huaxiong arranged for another drug to be dripped into a row of test tubes containing the vaccine, and the amount injected was so small that I couldn't see the drug in the dropper at first. The mixed vaccine is placed in a centrifuge and, after the program is set, the centrifuge is put into operation. Lu Huaxiong had another time to catch his breath, but he was excited and preferred to explain to us what he had just done.

"Do you remember how the plant vaccine brought by Yang Shanao will react to you?" Lu Huaxiong smiled at me jokingly, "The plant vaccine will stimulate the activity of the original virus in your body, and this is also the case for our vaccine, so I drip in a small amount of the plant vaccine to make the original virus in this new vaccine active, which will mask your normal genes and thus deceive Huang Weizheng's immune system." ”

"But will this also make Huang Weizheng become like Du Yuheng?" Chen Mo glanced at me with disgust as she spoke.

This didn't sound very comfortable, so I pushed Chen Mo and said angrily, "What do you mean?" ”

Chen Mo pretended to be innocent and pouted: "I don't mean anything else." ”

"Probably not. The reason why Du Yuheng became like this is that the mutation of the mutant gene of the original virus was activated by the plant vaccine. We have eliminated this part of the gene, so it should not affect Huang Weizheng. ”

It took a lot of effort, Huang Weizheng's body temperature finally dropped, and all the vital signs returned to normal. Lu Huaxiong also proudly announced that he became the first patient to be truly cured after being infected with the HTS89 virus, and the human vaccine for HTS89 was officially born. This is indeed a matter of pride and even an inspiration to the entire human community. However, I couldn't be happier, because this vaccine was developed in Zhang Xing's safe zone, which means that it must be used for it.

When they walked out of the underground layer together, Long Hao sighed and sighed: "It seems that Brother Niu has escaped death." ”

"The next thing is to wait for him to wake up."

"Come on, Brother Heng, look at your face is not good-looking, and you still have a sad face. Brother Niu is fine, what are you worried about? Long Hao patted me on the shoulder and joked, "Then again, you're really eccentric." I was bitten and your first instinct was to cut off my hand. Now that Brother Niu is infected, you are thinking about finding a vaccine for him. If the relationship is different, the treatment is really different. ”

Long Hao shook his head as if he was really serious, and I simply threatened: "If you talk nonsense, don't ask for the other hand." ”

"That's not good, next time my other hand is bitten, you'll kill me."

"If you don't accumulate virtue all day long and say something nice, you really don't want to live?" Liang Minxuan suddenly pushed Long Hao's head, and the force did not infer Long Hao's neck, which was considered a blessing to die.

Leaving the basement, a few of us went back to the living quarters on the second floor, where everyone stopped in front of my door, as if waiting for me to say something. In fact, everyone knows what they are going to face next, but they don't know when and how to speak.

Looks like I'm going to have to start with this. "That...... Aoyama's convoy is coming over later......"

"There's still more than an hour." Wei Hong looked down at his watch, "Since Zhang Xing has arranged dinner, it means that the people from Qingshan will have to stay for at least one night when they come to Wanxiang City, and they can't leave until the sun comes out the next day." ”

Wu Fei asked Wei Hong, "What do you think Zhang Xing will do?" ”

"What to do...... It can't be so blatantly a feast, right? ”

"I don't think it's necessary to Hongmen Banquet, after all, the words he said to me the day before yesterday don't look like he was going to do something to the people of Qingshan...... On the contrary, what I don't understand is why he is so sure that the people of Aoyama will come badly. ”

After I left Wei Hong's office the day before yesterday, I immediately found Wei Hong and told them everything Zhang Xing said to me. Wei Hong thought that since Zhang Xing would say this to me, it must mean that he was ready to deal with Qingshan's surprise attack, in other words, he had set a trap and waited for Qingshan's people to jump down.

"And why did he invite us all?" Chen Mo interjected, "It's understandable to say that you want to invite Du Yuheng...... But we ......"

"Maybe it's because we have been in contact with both sides, Zhang Xing did this to warn us and to cover for us, and Qingshan didn't dare to do it easily." Liang Minxuan's analysis has always been sharp.

"Anyway, everyone should be careful. We'll meet here an hour later, and we'll go to the feast together. "It's all speculation at the moment, so I simply asked my friends to go back and be prepared, and mentally have some precautions at hand that are the best.

Everyone agreed with my decision, and after a brief goodbye, they went back to their rooms. As soon as I returned to the room, before I could close the door, Chen Mo suddenly jumped in. As soon as she entered, she closed the door and walked up to me without saying a word.

"What are you going to do?" I looked at Chen Mo in surprise, my face suddenly became hot, and I sat on the bed in a hurry.

"What for? Don't think about it! When Chen Mo heard me ask, he immediately understood that I had misunderstood, and quickly stomped his feet and shouted.

"Then why did you suddenly run into my room like this?"

"Cut, who wants to come into your room, it's smelly and messy." Chen Mo glanced around my messy room in disgust; I can't blame me, I just returned to Wanxiang City the day before yesterday, although the room was not touched, but I left in a hurry at that time, and I was really too lazy to plan at ordinary times, no wonder she would dislike it.

"Let's talk about it...... What's the matter? ”

Seeing that I had returned to my serious expression, Chen Mo took a deep breath and handed me a small syringe that had not been opened. The syringe is probably the same as the one we used to get the hepatitis B vaccine in the past, except that it contains a turquoise liquid.

"This is what Sister Zhuo Jun asked me to bring to you." I was about to take the syringe, but Chen Mo suddenly withdrew his hand uneasily, "Hey! She said it was Yang Shanao's plant-based vaccine......"

"Well, I'm not going to use it right now." I snatched the syringe from Chen Mo's hand and carefully put it in the pocket of my jacket, "I asked her to get me some of this." ”

"What do you want to do here?"

"You don't care about that, just in case." I pushed Chen Mo to ask her to leave, you must know that this girl is not only blind but also worried, and she said that no matter how much she is, she can only make a mistake.

"Hey, Du Yuheng!" were all pushed to the side of the door, Chen Mo turned around suddenly when I was about to open the door, and in an instant, I was only a few centimeters away from face to face with her. In a trance, we both forgot what to say. Chen Mo hesitated for a moment, frowned and shouted back to the tone she used to speak to me, "You don't have to tell me what you're going to do, but don't mess around!" ”

"Oh...... Got it......" I looked at Chen Mo's moist eyes, but I lost the tone I usually had when I bullied her.

Chen Mo opened the door and was about to step out of my room, but the moment she stepped out of the door, she stopped. I looked at her hesitant back, as if time had frozen, only to see her look back and hug me tightly, and I was so scared that I didn't dare to say a word. I remember that when I was in Tianyang, she also hugged me like this, although it was short, I can still remember the temperature at that time. Merely...... It's just that the person she pretends to be in her heart is not me......

Chen Mo ...... I ......"

As soon as I spoke, Chen Mo's hugging hands immediately loosened, which made me regret a little, regretting that I had ruined this illusory beauty. Maybe it's a good time to talk to her, but I really can't open my mouth...... At this moment, Chen Mo actually stepped forward, and my face instantly felt the temperature of her face, and even burned because of it, and my heartbeat accelerated, and her nasal cavity was filled with her faint sweetness.

Suddenly, I forgot what I was seeing, and I only felt a small moistness on my cheeks. The cherry blossom-sized wetness soon dried, but I still felt the heat.

I was still hesitating, but Chen Mo suddenly pushed me away, she turned her back to me, lowered her head, and said in a faint or shy voice: "You must not leave me...... All right? ”

"Hmm...... Oh......" I hadn't recovered from what had just happened, but she had gone far away, and never looked back until she entered her room.

She just ...... Kiss me?

Qingshan's convoy arrived at Wanxiang City on time, but we didn't go to the maintenance room to greet us, but were directly "invited" to the place to eat by the people sent by Zhang Xing. Wanxiang City was originally a comprehensive large department store, and there were naturally luxury restaurants in it, but most of them were converted into warehouses or other uses. There are many restaurants on the first and second floors and even on the basement floor, except for the maintenance room. Several restaurants on the first and second floors have been preserved, and they have become a comprehensive canteen for ordinary Wanxiang City residents; Of course, you still need to pay for eating in it, which is the common currency of Wanxiang City - commercial coupons.

The place where Zhang Xing invited to eat this time was not on the first and second floors, but an abandoned restaurant on the fourth floor that was not used as a warehouse. After cleaning and simple furnishings, it has been reverted to its original appearance, but there is only one large table in the lobby of the entire restaurant. Come to think of it, since the entire Wanxiang is Zhang Xing's, it is not too difficult to charter such a magnificent thing as putting a table here. Directly opposite the restaurant is the scientific research laboratory of Wanxiang City. Although the last key research and storage location of the vaccine is not in this lab, the people inside are still busy. Although Lu Huaxiong had announced the successful development of the vaccine earlier, I am afraid that this person has not yet received the news, or he is still busy with some experiments that we don't know. Zhang Xing deliberately invited guests on the opposite side of the laboratory, probably also intending to let his potential partners see his strength.

The lights in the restaurant are not all turned on, which is not necessary and the second is due to the limited power supply in Wanxiang City. But even so, I haven't seen such a bright and clean restaurant in a long time. The main color of the lobby is maroon, and the large dining table is in the center of the lobby under the main lamp, as the main light source of the lobby, the large round table under the main lamp is particularly eye-catching, as if it is an opera stage that will perform the last supper. The table was lined with delicate silver cutlery, as if it were the exclusive tableware of the powerful lords of the European Middle Ages, and these dishes and chopsticks that glittered in the light were probably the most expensive tableware in Wanxiang City, and even the square towels for wiping hands were replaced with silk. Mahogany screens were placed in all directions of the dining table, and a few potted plants were placed with great interest. Next to each screen stood two scavengers, not armed with weapons, but I'm sure they must have pistols hidden under their coats.

When we arrived at the restaurant, Zhang Xing was already sitting in the main seat facing the entrance of the restaurant, pretending to be majestic and sunk in his mahogany carved Taishi chair. He wore a bright suit, and compared to the black and red tones in the restaurant, the well-tailored black suit and light blue shirt contained an unpredictable mind. Although I didn't wear a tie, this suit and leather shoes were enough to be considered the most formal style I have seen in the aftermath of the disaster.

"Sit down, sit down, I've got a place for you." Zhang Xing greeted us to sit down with a pleasant face, as if we were just having dinner later.

The scavengers standing under the screen each invited us to our own place. I looked at Zhang Xing uneasily, whether it was the soft carpet under my feet or Zhang Xing's leisurely smile, which made me feel uncomfortable. He did have a reason to laugh, but a few of us couldn't.

"What you ate today is something you haven't eaten in a long time." Zhang Xing was the only one among all the people present who was comfortable and relaxed, talking and laughing.

We all looked at Zhang Xing without saying a word, our faces full of doubts and uneasiness, and sat in the position that had been arranged by Zhang Xing first, accompanied by the guards beside us. We sat on opposite sides of the round table, and the two seats opposite Zhang Xing were still empty. The closest to Zhang Xing are Chen Mo and Long Hao; I sat down in the seat closest to Zhang Xing, and I knew the metaphor of Zhang Xing's arrangement. Chen Mo and I sat on the same side, and between us was Wei Hong. Long Hao's side is him, Liang Minxuan, and Wu Fei. The table was huge, so we were positioned a little further apart from each other. Compared to Zhang Xing's mahogany chairs, we sat in the same ordinary chairs in the dining room, but there were still equally luxurious cutlery in front of us, and the hot tea brewed in the teacups was steaming.
