"Actually, this kind of evolution is not too fast, after all, the average height on the earth now, such as the Netherlands, is more than 1.8 meters, if you think about it again, before World War II compared to the current average height, it is really not too fast. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

Chu Hao nodded, it is true that since World War II, the life expectancy of human beings, the average height and so on have increased tremendously, for example, in Huaxia, in the fifties of the last century, the average life expectancy suddenly changed from forty years old to seventy-six years old now, almost doubled.

In terms of height, there is no unified conclusion on the height of the Chinese people during the anti-Japanese period, and the general is that the northerners are relatively taller, with a height of 162-167, and the height of the southerners is between 157-165, and now it has basically risen by about eight to ten centimeters.

If you put it in the West, it is even more scary, the world's highest average height country, the Netherlands, the average height of men is 1.85 meters, and at the beginning of the last century, the average height of Dutch men was 1.67 meters.

This is not false, because at the time of the Second World War, the average height of German men was 1.69 meters, and by the 21st century, the average height of German men has exceeded 1.8 meters.

If this rate of increase is put into the situation where the Qin and Han Empires are more than a thousand years ahead of the current situation, the average height of more than 1.9 meters is indeed not too outrageous.

However, it is also important to know that from the end of World War II to the present, this explosive increase in life expectancy and height increase is due to the stability of life, the ability to eat well, and the rapid development and popularization of medical care.

In other words, this rapid growth is actually just making up for the previous arrears.

Even so, according to the law of growth, that is, the time from birth to maturity, and then divided by the average life expectancy, the current life expectancy of human beings is far from the original limit, that is to say, according to this calculation, human life expectancy can have a rapid increase.

"Indeed, the life expectancy of the Qin and Han empires of 800 years old has used a lot of genetic cultivation methods to clone the sick body of the patient, or some organs of old bamboo shoots, such as the heart and head, and then replace them, which can be achieved. Li Lingsu said.

Belch......

According to the previous life, the research on the head replacement technique was already going to be carried out, for the Qin and Han Empires, changing the heart and the head was really not a big deal, but Chu Hao still had a chilling feeling.

To tell the truth, Chu Hao would rather die than change his head, it's too terrifying, is it still himself who has changed his head.

"It's still yourself, the head that was changed, or your own head, the genetic sequence is exactly the same as your own, how can it not be you, if you don't want to continue to survive in this way, then work hard to cultivate, and when you reach the realm where King Kong is not bad, then you don't need to change organs like this, but with the current level of science and technology in this era, I estimate that you won't survive the moment when the head replacement technique appears." ”

After speaking, Li Lingsu glanced at Chu Hao with disdain, and then disappeared.

Chu Hao rubbed his nose and was hit by Li Lingsu again.

Now, Chu Hao seriously doubts how those movies that communicate with aliens and can get along with each other are made, which is not realistic at all, how can the aliens he met be so difficult to get along with, and they also have their own aura of high civilization.

Sometimes, Chu Hao will really be hit by Li Lingsu to doubt life, he feels that he is sometimes worse than Grandma Liu entering the Grand View Garden, and he doesn't know anything.

However, a civilization must always have a civilization process, as long as he works hard, Chu Hao believes that this era will always reach the height of the Qin and Han Empires.

And since he has come to this era, doesn't it mean that the fate in the dark is to lead this era by himself.

Thinking of this, Chu Hao instantly became high-spirited again.

In the system space, Li Lingsu's eyelashes curled slightly, revealing a pair of beautiful eyes that flashed with a strange light, and a smile slipped through the corners of her mouth, she really felt that the more she knew Chu Hao, the more she appreciated Chu Hao.

Be smart, hardworking, persistent, and never give up.

She rarely praises people, let alone praises a person with such words, she believes that with Chu Hao's existence, this era will definitely have a new look.

After coming to the classroom, Chu Hao glanced at it, and Han Lu and Xia Yun were not in the classroom.

However, the surrounding classmates flocked over, and the meaning of their words was similar to what Chu Hao had heard at the school gate before, but they seemed more enthusiastic, after all, they and Chu Hao had been together for three years.

Some classmates even took out a classmate record for Chu Hao to sign.

Chu Hao was stunned for a moment, it is said that this kind of thing should not be signed when the exam is approaching, how can it start now.

How did Chu Hao know that these classmates were preparing for the classmate record so early because of him.

Having a classmate like Chu Hao, a future great scientist, is naturally something worth showing off, and the best proof is that in addition to the graduation photo, it is the classmate directory.

But Chu Hao Shenlong saw the beginning and did not see the end, and no one knew when Chu Hao would come, so he prepared it early in order to meet the needs of the emergency.

When I saw Chu Hao this time, I naturally couldn't wait to take it out, after all, no one knew when Chu Hao would come next time, in case Chu Hao didn't come to school at all, and after the college entrance examination was over, he wouldn't come to school, so how could they, genuine classmates, prove it.

Chu Hao naturally didn't know about these twists and turns in his classmates' hearts, but he didn't refuse to come, and he also wrote a message or two.

However, slowly, Chu Hao felt that something was wrong, he felt that he had signed more than seventy copies, why were there still so many classmates around him, you know, there should be about sixty people in their class, anyway, he had been in the class for a while, and it was still clear how many people there were in the class.

Chu Hao looked up, and the faces of the people around him had been replaced by classmates from the next class.

He said that, no wonder there were so many, even the next class asked him to sign his classmates.

His lips smashed twice, yes, Chu Hao recognized it, and it didn't matter what class it was, he signed it all, but this message was waived, if he really wrote a message, he wouldn't be able to sign it tomorrow.

There's no way, it's all classmates in the same school, and being able to sign a classmate record with him is also to give him face, how can he reject people thousands of miles away.

However, he has already decided, and he will quickly settle the matter of Han Lu, he will never come to this school again, it is too terrifying.

Fortunately, not long after, Teacher Xiao Wang came and immediately relieved Chu Hao.

To tell the truth, so many students gathered in their own classes, which scared Teacher Xiao Wang to death, and thought that the students in several classes were fighting, and the college entrance examination was about to begin, but as a result, so many students were fighting, and the principal would definitely let him drink a pot.

However, Teacher Xiao Wang didn't expect Chu Hao to come to class suddenly, and when the discipline was almost maintained, he came down to ask Chu Hao, but Chu Hao was vague.

What are you kidding, can he tell Mr. Xiao Wang that there is a fire in his backyard.

The early self-study finally began, Chu Hao's eyes swept away, Han Lu and Xia Yun appeared magically, Xia Yun also gave him a sweet smile, and Han Lu directly looked at Chu Hao with a ponytail, without even looking back.

And when it came to the end of class, Chu Hao was going to find Han Lu, but Han Lu didn't give Chu Hao a chance at all, and pulled Xia Yun away as soon as class ended.

Chu Hao also wanted to chase him out, but he couldn't get out, and before he arrived at the door of the class, he was blocked by the classmates who flocked to him from other classes, which was all heard about the morning, and then came over to ask Chu Hao to sign the classmate's record.

In this regard, Teacher Xiao Wang is also helpless, this is the end of class, he really can't stop it, besides, this is a good thing, and no one knows what year Chu Hao will come next time, this kind of thing, he can only let it go.

When it was time for class, as soon as this group of classmates disappeared, Han Lu and Xia Yun magically appeared again.

In this way, every time after class, this is the case, and Chu Hao is not given any chance at all.

This made Chu Hao feel a little worse than dead this morning, he didn't know how many classmates he had signed, anyway, there were always three or five hundred copies.

Finally stayed up until noon to get out of school, Chu Hao didn't care whether it looked good or not, with an arrow step, his body was like an ape, and he came to Han Lu's side in an instant, and he couldn't help but pull Han Lu's wrist and run, which can be regarded as escaping.

This made the surrounding classmates' eyes shattered, they only understood at this time, no wonder Chu Hao appeared at school so strangely today, and the co-authorship was aimed at the class leader.

Listening to the bursts of boos and wolf-like howls around her, as well as all kinds of admiration, or the remorse of beating her feet and beating her chest, and consciously starting late, Xia Yun couldn't help but sigh.

A different feeling suddenly rose in her heart, as if she was a little darkness in the light, isolated and unique, and even a little drunk and sober.

However, she also sincerely hoped in her heart that Chu Hao and Han Lu would quickly reconcile as before, otherwise she would always have a sense of guilt.

Moreover, she slept very unsteadily last night, and she had a strange feeling about this home where she had lived for seventeen years, as if Chu Hao's home was her home.

Thinking of this, Xia Yun's face turned red instantly, and she seemed to be a little too ashamed.

Moreover, her parents were still a little strange, why did she suddenly come back to live, and thought that she had a conflict with Han Lu.

However, in an instant, this thought was left behind and fell into the happiness of her daughter finally coming home.

They didn't have no complaints about Xia Yun living in Han Lu's house for a long time, and they were worried about causing trouble to Han Lu's family, but seeing that Xia Yun's grades had been steadily rising, and she was also admitted to Huayin, and her personality became more and more cheerful, so they could only endure it.

They never suspected anything else, the first was that Han Lu and Xia Yun covered it up too well, and the other was that they had confidence in their daughter and knew that she would not mess around.

They could know that their precious daughter, the pearl in her palm, was almost swallowed by Chu Hao.

Running out of the school gate for almost a kilometer, Chu Hao stopped, looked back at Han Lu, and saw that his face was not red, he was not panting, except for his hair was a little messy, there was no sign of sprinting at all.

Oh, too, Han Lu used to be the principal of the running team, and she also won the national second-level athlete.

Han Lu twitched his hand vigorously, Chu Hao couldn't help but smile, and quickly let go of his hand, he forgot that he had already held Han Lu's wrist.

Han Lu lowered his head, didn't look at Chu Hao, didn't speak, lowered his head, and kicked the stones on the ground all at once.

Seeing this, Chu Hao suddenly smiled, Han Lu grew up, and when he was panicked, he was what he was now.

Coughing lightly, Chu Hao said, "Why didn't you go home yesterday." ”

"I went back, why didn't I come back. Han Lu said without raising his head.

"I mean, why didn't you go to my house. ”

"That's your home, not mine. ”

Hearing this, Chu Hao smiled wryly, and couldn't help rubbing his nose, he felt that he couldn't talk anymore.

"Okay, you can laugh if you want, yes, I lied to you, your mother really didn't let me look at you. Han Lu suddenly raised his head and said expressionlessly.

Chu Hao felt like he was choked to death in an instant, he was really wronged by Dou E, he really didn't laugh, let alone want to laugh.

"Yes, that's right, I like you, I've liked you since I was seven years old, and the reason why I lie is that I want to live with you, every day, every moment. Han Lu continued to say expressionlessly.

This should be a touching love story, but in Han Lu's mouth, when he said it, there was a feeling of coldness, which made people fall into an ice cave, and even his whole body was frozen.

"But I don't dare to say it, I don't dare to go beyond the slightest, for fear of losing you, for fear that after I say it, I won't even have to be a friend. I'm afraid that after leaving you, I won't even dare to reminisce, because my thoughts and regrets will erode my heart like poison, or I can't sleep all night, or I will be in a trance for a long time, and I dare not forget, because without you, my whole youth will be empty! Now you are satisfied, laugh if you want to laugh. ”

As soon as the words fell, Han Lu looked straight at Chu Hao, as if he was crying, but there was a strange stubbornness in his eyes.

Chu Hao was stunned, he also looked at Han Lu, his heart was mixed, or it was like a stormy wave.

To be honest, he really didn't expect that Han Lu would like him so much, this kind of liking has been engraved in his bones and engraved in her soul, and Chu Hao didn't expect that he would be so important to Han Lu, and even has risen to the point where youth has no light and is full of darkness.

He felt a little bitter at the corner of his mouth, Han Lu's words sounded to him like a cry of blood, and the words pierced his heart as deeply as a knife.

Perhaps because of the differences between men and women, little girls often wake up very early, but boys are still in a period of ignorance.

However, this is definitely not the reason why Chu Hao has ignored Han Lu for so many years.

However, what made Chu Hao feel even more worrying and painful was that this life was like this, and that was the same in the previous life, I am afraid it was also the same.
