"Li Qing, Chen Zihan, you report an address. Pen fun Pavilion www.biquge.infoMK1 It will send you home, that's all. ”

didn't say more, there was no plot of making a personal promise, and there was no imaginary reluctance between the three of them, maybe they were all homesick.

After Zhang Yang made some explanations, the three MK1s scattered in the air in three directions, each heading in their own direction.

When I got home, even though it was getting late, my parents and Ye Ningxue were sitting in the living room watching TV and chatting.

Seeing Zhang Yang tiptoe into the living room, his parents immediately spoke.

"Xiaobao, how many times have I told you, career is important, but family is equally important. Can you take care of your home a little more? Father Zhang stood up and walked to Zhang Yang's side: "One more thing, what kind of medicine is the medicine that your mother and I are drinking?" ”

There was no question between father and son, a gentle tone, and peaceful eyes looked at Zhang Yang, even so, Zhang Yang was a little embarrassed and turned his head.

It was with Ye Ningxue's resentful eyes, that feeling, it should be resentment, Mother Zhang and Ye Ningxue stood up together, their eyes were full of inquiry.

"Well, didn't I say that? Sit down and say, sit down and say. Zhang Yang pulled Ye Ningxue, the scene was slightly embarrassing, how could this past matter be brought up again?

"Hmph, you're just making it up. See, what is it? ”

Ye Ningxue rummaged through her bag, took out a stack of documents, which were inspection sheets written in black and white, and handed them to Zhang Yang.

"What is this?"

Zhang Yang took the document and looked at his parents' clear looks, knowing that they were angry with each other, which made him even more embarrassed.

coughed twice, looked through it carefully, and found that this stack of documents was the physical examination list of everyone in the Ye family.

Among them, Ye Lao's is the most special, which was placed on the top by Ye Ningxue, and marked emphatically, almost the moment he saw Ye Lao's list, Zhang Yang understood what was going on.

"What's going on?"

Zhang Yang shook his head, with a confused expression on his face, looking at the three people with slightly unkind faces, he couldn't help but complain in his heart.

How is this like three triages, one, two, three, four, how can I be the least one......

Before Zhang's father and mother could speak, Ye Ningxue twisted Zhang Yang's waist fiercely, glared slightly, picked up a bunch of materials and patted Zhang Yang gently: "Also, what's wrong?" Don't tell me yet! “

There was a little grievance in his expression, and he pouted: "Pretending to be confused, now the entire Ye family knows about it!" This physical test report from grandpa! “

What pH, carbon dioxide partial pressure, oxygen partial pressure, bicarbonate ion, sodium ion, potassium ion and other data.

Zhang Yang didn't understand a lot of terms such as chloride ions, proteins, urine sugar, red blood cells, white blood cells, urate crystals, etc., and Zhang Yang didn't understand them, among which the diastolic blood pressure and systolic blood pressure that were particularly prominent and highlighted were kept within the numerical range.

"Grandpa has high blood pressure, but he got better after taking your medicine!" Ye Ningxue paused, "Then the doctor who tested it and our family's personal doctor both said that grandpa's physical condition is very high now, and it seems that all the diseases on his body have been removed." “

And after that night, Grandpa himself said that he felt much better, as if he was much younger! If it weren't for grandpa's protection, I'm afraid someone would have come to the door by now. ”

"Heh, heh, that's a good thing! I want my grandfather to live a long life! ”

Zhang Yang smiled, no longer entangled in this problem, and lay down on the sofa as soon as he hugged Ye Ningxue, his eyes flashed with a strange light, but after a while, he returned to normal.

"Do you live a long life?" Ye Ningxue leaned back on the sofa, her eyes as bright as black jewels with a bit of hope.

"Yes, I think that living a long life is an important step in the evolution of human beings. Then there is the improvement of genes and inheritance. “

Zhang Yang looked at the few spectators, only three, stood up and walked to the sofa, and began to confide in his heart with great interest.

"I believe that there will definitely not be only human beings in this universe, and human beings may only be in the middle and lower levels of cosmic civilization, and I think one of the important factors restricting the development of human civilization is lifespan."

Zhang Yang spread his hands, his eyes drifting to no avail, recalling the process of making the genetic potion, which was made according to another humanoid creature. There must be a source for the system, perhaps it is the crystallization of this race's civilization.

As soon as this question was mentioned, the interest of the three of them was raised, and they looked at Zhang Yang with interest: "And then?" “

"The lifespan of a human being is only about 100 years, and of course it is much more fortunate than mayflies. But this 100-year period is nearly 20 years in China. “

"Even for 30 years, we spend it on learning, and the efficiency of learning is not very high...... And for the average person, the working hours will be even longer. “

"Now all countries rely on top specialists, and this group of talents is the core of the country's progress in the field of science and technology, but there are too few such people......"

Zhang Yang put his hands together and touched his face, and continued: "If I want to promote the process of human civilization, the first thing to do is to extend the life span of human beings and create a more superior and good environment. ”

Zhang Yang wrenched his fingers and said, although this idea seemed ridiculous to some people: "Second, find a way to speed up the efficiency of human learning. “

"Third, improve the human gene pool and solve problems in all aspects, as if it were war or something."

It seemed that the whole person was a lot more relaxed, Zhang Yang slowly exhaled, the corners of his mouth were slightly upturned, he had been confused and puzzled. Even in extreme cases, I want to take my family away, but I can't go after all.

Earth, China. After all, it is their own roots, if you leave here and go to an alien planet, not to mention when you will be able to find an alien civilization, if you can't find it. Could it be that a family wandering in the stars, without the feeling of being the same kind is lonely after all.

"All right, my good brother." Ye Ningxue's eyes were full of smiles, and she grabbed Zhang Yang and asked him to sit down, but obviously she didn't believe it.

It is conceivable how difficult it is to promote the process of the entire civilization on your own.

Zhang's father and mother smiled, but said in unison: "I believe Xiaobao." ”

However, Zhang Yang has already created many miracles, hasn't he?

"Yes, yes." Zhang Yang nodded, and a soft place in his heart was touched again: "If the third step is completed, maybe we will already encounter an alien civilization by then, and this is a tricky problem." ”

Zhang Yang touched his forehead, he was not a pessimist, but when it came to the direction of the entire civilization, he always thought of the worst, and things like the electromagnetic waves emitted by the United States and Britain in recent years were disguised by Zhang Yang.

Zhang Yang is not like them.

"Assuming that the civilization encountered is an unfriendly civilization, then war is inevitable."

At the mention of this issue, Zhang Yang closed his eyes, not wanting to say any more, the inevitable war, standing to win, or lying down to die. Or retreat without a fight, and that can only be the case.
