Chrissy got the blood analysis report and frowned tightly. She frowned and stared at the analysis in silence. Lu Li didn't urge, just stood aside silently.

Chen Yuxin looked at the two who remained silent, and was very envious. Both of these are so young and equally powerful. More importantly, there seems to be no barrier between these two people, and there is absolute trust between them. For a moment, she was a little distracted.

After a long time, Chrissy raised her head and instructed Chen Yuxin, who was distracted on the side.

"Take him for a full body check-up."

"Good...... Good. ”

Chen Yuxin woke up, nodded again and again in a panic, and left the real room with Lu Li. Two hours later, the two returned to the room.

At this time, Chrissy was intently observing in front of the microscope, and she didn't even notice that the two of them had returned. Chen Yuxin walked over and put the physical examination report next to the microscope.

"Oh, I'm sorry."

Chrissy was stunned, then turned her head and smiled apologetically at Chen Yuxin. The latter blushed and shook his head again and again: "No, no, no, it's me who interrupted your work." ”

Chrissy smiled, not too entangled with Chen Yuxin in such a trivial matter. She turned, a hint of joy in her tone that couldn't be hidden.

"That mystical dopamine level in your body is ten times higher than before. And ......"

She deliberately elongated her tone. Chen Yuxin was immediately occupied by curiosity, and pricked up her ears to wait for the following explanation. But Lu Li was indifferent, as if he had seen through this little trick.

"What a piece of wood."

Chrissy grumbled, and then her eyebrows jumped up with joy: "And I'm sure there is potential for this dopamine to be further improved in the future." ”

"What do you mean?"

Lu Li frowned slightly. He looked at Chrissy with doubts in his eyes. Chen Yuxin also looked at Lu Li in confusion, and then at Chriss, and finally had a lot of thoughts, guessing what Chrissy's words meant.

"Dopamine? Potential for lifting? What do you mean? ”

Chrissy grinned, avoided answering, and turned her head to Chen Yuxin, who was distracted on the side, and commanded.

"Take him for another head CT scan."

"Ah...... Oh. ”

Chen Yuxin was once again awakened by Chrissy from her distraction, and hurriedly left the real room with Lu Li. Doing a CT scan of the head is much simpler. Not long after, the two returned to the real room with X-rays.

Chrissy took the X-ray that Chen Yuxin handed over and pointed straight to a shadow the size of two fingers on her head. Lu Li looked at her fingers, and his heart suddenly moved.

"That gland has gotten bigger."

"Not bad."

Chrissy pulled her sideburns and nodded affirmatively, "It's getting bigger." ”

Lu Li hesitated and asked uncertainly, "Is it ...... Can it still grow? ”

"Judging by the facts as it stands...... Yes. ”

Chrissy sighed regretfully: "It's a pity that the current conditions don't allow it. I can't find a reason for that. I'm sure of one thing, though. It must have been stimulated in some way before it started to grow. I recommend that you have a CT scan of your head once a day, and then come to the real room for a check-up. I need more accurate numbers. If I can figure out the key, I can develop a more powerful human strengthener. ”

Hearing this, Lu Li's eyes immediately changed. He nodded without hesitation and accepted Chrissy's proposal. Then, he dropped a sentence and turned and walked to the door.

"I'll explain a few words."

Out of the real yàn room, Lu Li came to the hall on the first floor. The situation at this time is much better than the day before yesterday. The zombies outside couldn't break through the obstacles for a long time, and most of them had dispersed. Only a dozen or so zombies were still hovering at the door, colliding twice from time to time.

Liu Qiang and the three of them stood in a corner of the hall chatting. When they saw Lu Li coming, they all cast their eyes on it. Lu Li stepped closer. Liu Qiang took the initiative to ask.

"How?"

"Okay...... No, it should be said that it is good. ”

Lu Li wanted to laugh, but he couldn't control the muscles on his face. He had no choice but to give up and continued, "Chrissy has already set the course. These days I need to stay in the real yàn room to help her collect the numbers, and I'm afraid I won't have time to go out and look for food and diesel. ”

"No problem, I'll leave these little things to me."

Liu Qiang immediately took on this task. As soon as he said this, he remembered the enhanced zombies he had faced not long ago, and couldn't help but laugh bitterly at himself.

"As long as I don't encounter the kind of enhanced zombies below, I should be able to handle it."

"I'll go with you."

Chen Song took a step forward and came to Liu Qiang's side. He also smiled wryly and shook his head: "Two people act together, and there is more or less a response." ”

Lu Li was silent. He knew that those enhanced zombies in the basement had left a shadow in the hearts of Liu Qiang and the others. made the two extremely unconfident in their own strength. His gaze swept over the faces of the two of them for a week, and then commanded.

"You punch me."

Liu Qiang was stunned, and immediately understood what Lu Li meant. He shook his head and turned to face the wall. He raised his fist and secretly exercised his strength. With a muffled cry, his right fist slammed into the wall.

There was a muffled sound, and the wall slammed. Cracks spread like spider webs under his fists. He withdrew his right fist and looked at the shallow pit left by the wall, a hint of confidence on his face renewed.

This result is not much different from Lu Li's original punch.

Chen Song immediately rejected Lu Li's kindness and learned Liu Qiang to punch the wall. The results are similar. is only slightly inferior to Liu Qiang.

"That's enough."

Lu Li looked at the spiderweb-like crack on the wall and rubbed his cheeks: "Those things in the basement are just exceptions. If they all have that power. Now City A has fallen. I'm sure that if this happens, there won't be more than ten people who will survive. ”

Liu Qiang's faces changed suddenly. They are also aware of the same results. If zombies really have this kind of power, they are comparable to, or even surpass, the running speed of humans. Few of the survivors of City A were able to escape their clutches.

"But we still have hope."

Lu Li saw the worry on the faces of the three of them, and truthfully told Chriss's discovery: "Chrissy has found a way to further strengthen the human body. If things go well, we'll have a chance to complete the second generation of boosters before all the zombies evolve into the kind of monsters below. At that time, our strength will reach this level. ”

With that, he stepped forward and punched the wall. There was a loud bang, and the dust flew. There was a deep hole in the wall. This punch directly pierced the wall more than 20 centimeters thick.

Liu Qiang's eyes widened suddenly. They looked at the gaping hole in the wall in disbelief, shock written across their faces. After a while, Liu couldn't wait to ask.

"This ...... Is this your true power? Did you retain your strength before? ”

"Nope."

Lu Li shook his head: "The punch before was indeed my real level at that time. However, in the battle in the basement just now, my strength has increased inexplicably. ”

As soon as the words fell, Chen Song couldn't wait to ask, "Can we be like you?" ”

Lu Li nodded and said truthfully: "If Chrissy's idea is correct. When new boosters appear, not only you, but all survivors will have such power. ”

The three of them were stunned again. After all, Chen Enxin is old and serious. He quickly understood Lu Li's thoughts. He hesitated for a moment and asked uncertainly, "Are you going to make this human enhancement public?" ”

"Hmm."

Lu Li replied in a deep voice: "There are a lot of them. Now there is a unified command and dispatch again. If humanity is not united, it will not be two years before there will be no more human beings on the planet. They have a lot of advantages over us. It doesn't get tired and doesn't need to be refueled. And we will be tired, we will be hungry. ”

Chen Enxin sighed: "I understand. But I want you to think it through. It's okay to make this human body booster public, but we'll have to wait until we get a strong enough lead. ”

Speaking of this, he shook his head self-deprecatingly and smiled: "Human beings claim to be the spirits of all things. But we humans ...... Xunzi once said that human nature is inherently evil. This statement is not false at all. There are many good people in society now, and there are even more people with dark hearts. Once this human enhancement is obtained by such a person, I am afraid that the impact will be greater than that of those zombies. ”

"I can't care about that much."

Lu Li looked away, looking very helpless. Chen Enxin's words are not false at all. Ideas such as meritocracy have become the mainstream of today's society.

For the sake of profit, someone can disregard the lives of hundreds or thousands of people.

For the sake of profit, fratricide, brotherhood and other incidents have occurred repeatedly.

Liu Qiang and Chen Song heard Lu Li's helpless sigh, and they felt very uncomfortable in their hearts. They didn't understand what Chen Enxin said. Chen Song, in particular, empathizes.

The eldest brother drove away his parents under the prodding of his sister-in-law, and let the second elder fend for himself, never asking. Family affection is annihilated, and discipline does not exist. How sad it is.

At this time, Lu Li noticed that the atmosphere was a little heavy, so he quickly changed the topic: "I'll think about these things later." The most important thing now is the research and development of the second generation of human strengtheners...... and vaccines. ”

……

Back on the second floor, Lu Li walked into the real room. As soon as he came in, Chrissy couldn't wait to order Chen Yuxin: "Draw fifty milliliters of blood first." ”

She watched Chen Yuxin draw blood for Lu Li, and solemnly said the arrangements for the next period of time: "Starting tomorrow, the whole body will be examined in the morning and the test will be conducted in the afternoon." You can get out of this room, but you have to be on call. ”

Lu Li nodded, no objection.

At this time, Chen Yuxin had already finished drawing blood and had just pulled out the needle, and the needle hole had disappeared without a trace. She was taken aback, and as if she didn't believe it, she picked up Lu Li's arm and searched carefully.

"Don't look for it. It didn't take him a few seconds to heal from that little wound. ”

Chrissy walked over and took the test tube from Chen Yuxin's hand and explained casually. Chen Yuxin smacked her tongue secretly.

Is this still human?

……

For three days in a row, Lu Li was "tortured".

Chrissy tried countless methods in order to find out why he was further strengthened. Hot and cold stimuli, electric shocks, and even tried acupuncture with the help of Chen Yuxin. But after three days of busyness, nothing was found.

This morning, Lu Li finished his routine examination and drew another 100 milliliters of blood with the help of Chen Yuxin. He got up from his chair and planned to tour the building while Chrissy was struggling to figure out what to do next, so that the zombies would not have slipped into the building and everyone would not know about it.

At this moment, Chrissy suddenly walked up to him. He saw the solemnity on Chrissy's face, and without waiting for her to speak, he took the initiative to say in a deep voice, "What do you need me to do." ”

"I've tried to stimulate your body with hot and cold stimuli, electric shocks, and so on. Unfortunately, no changes were found. According to the results obtained in the past few days, the number of jù in your body has not changed, and only a few areas have increased slightly. ”

Chrissy walked over to the desk, picked up a syringe containing a small half-gray liquid from the table, and walked back to Lu Li. She held up the syringe and said solemnly.

"So, I intend to work on new boosters and viral vaccines at the same time."
