After that, Cheng Hua left the scene with the girl and Shakespeare, while Qin Yi went downstairs alone to prepare to go home. Because the white suit didn't want the matter to be revealed, the scene had been blocked in advance, and the construction sign was hung on the road here to temporarily prohibit traffic, so no one came to check on the commotion just now.

After going downstairs and resting for a while, Qin Yi's symptoms were also relieved a lot. At least now my head is clear, not as heavy as it used to be. Although the Reverse Scale Organization was afraid of any of his qualities, he still had to be careful.

After confirming that no one was following him, Qin Yi returned home, and Xia Yuxin immediately greeted him.

"How's it going? You look sick again. Xia Yuxin frowned and said.

"Running a lot. Qin Yi replied with a smile, he didn't suffer any injuries in the confrontation with the King of Spades, although he took a few punches from the other party, but fortunately, his body was tough enough, and the attack of this level was not enough to cause him any obvious external injuries. The key is the sequelae caused by this virus. However, it seems that Cheng Hua has not been affected by this virus.

Thinking of this, Qin Yi groaned: Cheng Hua was not affected by the virus, is it really just because he exercised a lot?

Qin Yi took a bath, and the hot water made his brain a little clearer.

He vaguely remembered that Cheng Hua was actually responsible for the A virus and B virus at the beginning, and at that time Cheng Hua seemed to be infected by the A virus and entered a feverish state, and his female colleague had to call Qin Yi for help. Thinking about it like this, Qin Yi couldn't help but wonder, maybe Cheng Hua was not affected by the virus, and there was also this reason?

After Cheng Hua settles Shakespeare, he should come to him, and Qin Yi is ready to communicate with him later.

After taking a bath, Qin Yi came out while wiping his hair, but after taking a bath, his head became heavier and heavier.

"Xiaoyi, come and lie down. Xia Yuxin pressed Qin Yi and sat down on the bed, "The area around your eyes is red again." ”

"Hmm. Qin Yi stroked her cheek, and then sighed, "It's time to sleep." ”

Saying that, Qin Yi lay down on the bed, Xia Yuxin covered him with a blanket, and the moment Qin Yi closed his eyes, he felt that the whole person was spinning and was sucked into the abyss. After a long sleep, and I don't know how long it was, he felt that someone was gently patting his face, and when he opened his eyes, it was Xia Yuxin's gentle smiling face.

"Xiaoyi, Cheng Hua is here. Xia Yuxin said with a smile, "He said to talk to you for a few words and leave, and then sleep later, right?"

"How long have I been asleep?" Qin Yi asked, rubbing his eyes, feeling much better.

"It's only been three or four hours, and I ordered takeout, and after telling him, it should be just right to be delivered. Xia Yuxin pursed her lips and smiled.

Qin Yi nodded, then sat up from the bed, Xia Yuxin went out to give a notice, and then Cheng Hua strode in, came to the bed, pulled the chair over on the side, sat down in front of Qin Yi, hugged his arms, and shook his head.

"Why? Looks like he's disappointed in me. Qin Yi didn't have a good breath, "I live with a clear conscience." ”

"You're so lacking in exercise. Cheng Hua said in a deep voice, "Although you said that you can't rely too much on violence, but after all, you are an agent, and your physical ability is still very important, even if you don't fight......"

Qin Yi raised his hand impatiently to interrupt him, and continued: "Don't make up your mind too early, okay? Then according to what you said, Hawkeye has exercised a lot more than me, isn't he also restricted by the virus, and now he can't participate in the mission? My body is already very healthy." Let's talk about something else, I have something to confirm with you. Who sent you?"

"Instructor Sherlock. Cheng Hua crossed his arms and replied, "It seems that the organization has captured the information that the white suit is active in Nanhua City, and then I heard the information that Shakespeare sent you last time, so I naturally paid more attention to your safety." Recently, the field agents in the organization have been infected by the virus, so they sent me here. As soon as I got the news, I rushed to your side. ”

"Sherlock Instructor...... Qin Yi nodded, and then continued to ask: "Do you remember when you were looking for the A virus before, you were infected once? That time you were infected with the A virus and then injured again, so your female colleague from the law firm called me for help, do you remember this?"

"You're saying that my lack of symptoms of the virus has anything to do with this?" Cheng Hua asked with a frown.

Qin Yi nodded: "Yes, although the A virus can't break through our body's immune system, it must still remain in your body, some viruses are in a latent state and have not flareed up, but they can already play the role of 'marking'." ”

Cheng Hua looked at him with a blank face and asked, "Then, can my blood ......?"

"No, I can't. Qin Yi shook his head: "Your blood can't make a serum or vaccine, the A virus in your body is just used as a 'marker' so that you are not infected by the B virus, you are not immune to the B virus, but you will not become the target of infection." ”

As he spoke, Qin Yi pointed at Cheng Hua: "Therefore, the organization should be able to use your blood sample to make a 'preventive shot', extract and replicate the A virus in it, and inject it into other agents to prevent them from being infected." And the agents who have already been infected have no choice, and now they can only wait for the vaccine to be made. ”

Cheng Hua nodded: "This can be regarded as useful information, in short, I will organize the production of 'preventive shots' first." The vaccine is now being studied in full force. However, I am afraid it will be a week or two before the research is completed. ”

"It's okay, it's just a daily life, the virus doesn't attack. Qin Yi replied lightly.

"So, during this time, you can only be an honest high school teacher. Cheng Hua snorted, and then handed him a manual and a bag, "Here, there are some existing research data on this virus and temporary response plans, these drugs can delay the onset of the virus, just in case." ”

Qin Yi nodded, and then Cheng Hua stood up and turned to Xia Yuxin, his whole person became a lot more easy-going.

"He'll give it to you. Cheng Hua smiled gently at Xia Yuxin, who smiled and nodded: "Don't worry." ”

"Wedding, I'll be there. Cheng Hua said, grabbed his blazer from the side, and then pushed the door and left.

Not long after Cheng Hua left, Xia Yuxin also took takeout, and Qin Yi checked the conditions for the outbreak of the virus and the response plan while eating. It turns out that the virus attack is related to the "basal metabolic rate" of the person.

This condition is triggered when a person consumes more than twice the average amount of calories from their basal metabolic rate.

For example, Qin Yi's current basal metabolic rate is about 18 to 2,000, so his calorie metabolism per hour is less than 100. So if he does strenuous exercise and burns 200 calories in an hour, the virus will attack, causing his body to be weak and tired, and thus his thinking will slow down.

However, there is a certain peak requirement for this seizure, which must be continuously maintained in a physically active state for a period of time before it can be triggered. For example, if you consistently consume 100 calories within 30 minutes, then the trigger condition will be reached. But if you burn a hundred calories in five minutes, the next twenty-five minutes are resting, and it won't be triggered.

So, this one was basically invented for these agents. Because the agents keep their bodies active when they carry out their missions, whether it is moving, gunfighting, or hand-to-hand combat. If you can find an opportunity to keep your body calm for a while, you can stop the onset of the virus. Of course, this is not so easy to do.

However, based on this, the organization has produced some drugs that can delay the "counting" time of the virus. The limit time was postponed from half an hour to two hours. In other words, after taking the drug, they can continue to be active from 30 minutes to 2 hours, and find an opportunity to calm their bodies back to a state within two hours to avoid the virus attack.

"In this case, you can act normally. Qin Yi looked at the two needles in his hand and thought secretly.

But this drug is not invincible, the human body is resistant, and these super humans are originally non-disease-free existences, so their drug resistance is higher than that of ordinary people, and this reliever can only take effect twice.

After two sessions, there is no way to have any effect on this reliever. So it must be used with care. The basal metabolic rate of the human body is basically related to the muscles in the human body. The higher the muscle content, the higher the person's basal metabolic rate, like Cheng Hua's basal metabolic rate can reach a terrible degree of three thousand to three thousand five.

The basal metabolic rate is actually the calories consumed by the body when a person does nothing for a day. So these agents need to eat a lot of food every day, or eat junk food that is higher in calories to replenish it.

However, this also just shows that Qin Yi's idea is correct, Cheng Hua is not affected by the virus because he is strong. Because although Cheng Hua's basal metabolic rate is higher, if he has too many muscles, his daily behavior consumes more calories, so it is the same consumption ratio.

Qin Yi sighed secretly and put these injections into his arms: "Anyway, let's resume class first." ”

"Well, your students are waiting for you. Xia Yuxin said with a smile.

"I've worked hard for you these past few days. Qin Yi pinched her little nose and said, Xia Yuxin shook her head: "It's not hard, it's because I've been too lazy for a long time and handed over everything to you, so I made you tired......"

"It really is. Qin Yi nodded and said seriously, "So tonight I will punish you to sit up and move by yourself." ”

Xia Yuxin puffed out her cheeks and glanced at him, then got into the quilt and whispered: "If you move yourself, you will move yourself......"

The next day, Qin Yi returned to school. In the two days since he was sick, the school's basketball team has won the championship of the high school basketball league, which is also the first league championship won by their school.

"Okay, the teacher will officially come back to class from today. Qin Yi said with a smile, "I heard from other teachers that everyone seemed to be doing well during the teacher's absence, so I praised you." ”

"It's not because the squad leader and deputy squad leader are too strict......" Huang Tianming muttered with his chin propped up.

"That's because," Hua Yun glared at him, and said angrily, "It's because we usually cause too much trouble to the teacher, and the teacher will be tired." Think about it for yourselves, how much Teacher Qin has to do for us. Although we were mixed in class, we were always supervised after class, and after school, we had to go to the basketball team as a supervisor, and we had to take care of our living conditions in our leisure time. ”

"What do you mean by mixing up in class?" Qin Yi frowned and asked dissatisfiedly, "The teacher's class level is not very good, but the teacher is definitely very serious in class." Open the textbook, where have you been?"
