In October, Jinyang Wushuang Fuzhong.

"Uncle, don't worry, didn't Yuan Hao and Zhongjing already say it? Xin'er and both of them are in very good condition. And with the presence of two nurse doctors in the former Imperial Doctor's Department, plus Yan'er and them, there will be no problem. Li Yi looked at the nervous Qiao Yu and continued to be relieved. But even so, worry flashed in his eyes from time to time.

For Li Yike, he knows very well how dangerous it is to have a child in this era, such as Li Yi's mother Yan Yun, who died because of difficult childbirth. Once the birth is difficult, it is easy to cause heavy bleeding in the body of the pregnant woman, even in the later generations with extremely developed medicine, this situation is a very dangerous thing, let alone in this era when even blood transfusion is not possible.

Once this happens, then the only option is a caesarean section. Yes, there have been caesarean sections in this era, such as in the [Historical Records]. However, this surgery can be very dangerous in the absence of blood transfusions and in an adequate medical setting, whether it is heavy bleeding or postoperative infection. This is why once this surgery is performed, you can only choose between a wife and a child.

At the same time, it is precisely because of this huge risk that the population in ancient times was very low. Yes, food production is one of the reasons for the slow population growth, but in fact there was a very, very large amount of uninhabited open space in ancient environments. Just like the current Han Dynasty, before Li Yi attracted a large number of displaced people, the population of Bingzhou was only 780,000, but now, it has exceeded 1.6 million.

With an additional population of nearly one million at once, it is naturally impossible to support it with the existing arable land in the state. And the reason why they are still living in Bingzhou, and even the population is still growing, is because Li Yi has carried out large-scale land reclamation in various parts of Bingzhou, turning the original wasteland into arable land that can be planted, and then producing more food.

It is also like Jingzhou today, a Nanyang has a population of more than 3 million, while Wuling County, which is nearly twice the size of Nanyang, has a population of more than 300,000. This obviously cannot be due to the lack of food production, but because there are simply not so many of them!

In fact, the first population explosion period was due to the first industrial revolution, in which not only epoch-making machinery such as steam engines appeared, but more importantly, modern medicine also developed rapidly.

After all, food or something is just a treasure for the living, and for those children who have just come into the world, the only thing that keeps them alive is medical skills. Not only at birth, but also at infancy.

I don't know how long it took, but for the two men in the courtyard, it was undoubtedly an extremely difficult time. It wasn't until they heard two crisp cries in the house one after another, and at the same time saw a nursing doctor walking out with a happy face, that the two finally let go of their hanging hearts.

But when the nurse was about to speak, Hashiha's heart that had just been put down hung again. "It's a boy! It has to be a boy! Hashiha prayed secretly in his heart.

Speaking of which, although Li Yi promised to pass on the first boy born to Qiao Xin's two daughters to the Qiao family, Qiao Yu himself did not wait. Over the years, he has taken in three concubines, but he has not even conceived a child.

"Congratulations! It's two sons! The nurse smiled happily, after all, in these years, if a boy is born, the host has always been very generous.

Is Li Yi generous? There was no doubt about that, of course, although he wanted a daughter more because he already had three sons. But in any case, adding two more sons is a great joy for Li Yi.

"Uncle, then let the child born to Xin'er inherit the Qiao family." Li Yi looked at Qiao Yu, who breathed a sigh of relief, and chuckled.

"Good! Good! Good! Qiao Yu nodded in response, it seemed that at this time, apart from these three good words, he couldn't think of anything else.

However, Li Yi is not incomprehensible to this, Mencius Zeng Yun, "There are three unfilial pieties, and no queen is great!" In fact, for the people of this era, passing on the family line is always the number one event in life, let alone for a famous family like the Qiao family.

If Hashiha hadn't been able to give birth to a son to inherit the Hashimi family until he died, I'm afraid he wouldn't know how to face Hashigen under Izumi.

"Hehe~" Seeing Qiao Yu's appearance, Li Yi smiled secretly, and at the same time couldn't help but feel a little proud in his heart. After all, he is only twenty-eight years old this year, but he already has five sons, although two of them were passed to the Cai family and the Qiao family respectively. But I have to say that this efficiency is very amazing.

And for a local commander like Li Yi with huge power, having many heirs will also make his subordinates feel more at ease to work for him. After all, in the troubled times, no one can guarantee how long they can live, and having enough heirs is the goal that every force is pursuing.

Soon, the news of Li Yi's two more sons spread all over Jinyang City, and countless officials and people rushed to congratulate him, and Li Yi received all kinds of gifts. In the end, more than a dozen personal soldiers had to be sent at the door to be responsible for receiving gifts.

"I'm afraid there are very few officials like a gentleman who are loved by the people, right?" Lying comfortably in Li Yi's arms, Cai Yan looked at the mountains of various gifts and smiled proudly.

"Hehe~ That's of course~" Li Yi smiled proudly when he heard this. Well? Actually, there are quite a few? So what? In front of your own woman, being too modest is not a good thing.

While celebrating the birth of Li Yi's two more sons, Sima Hui and others also congratulated Qiao Yu, "The Qiao family has successors since then, but Yixiao can rest assured~" Zhang Zhi joked with a smile.

It's just that this cheerful atmosphere didn't last long before it disappeared.

"Yuan Hao! Zhongjing! Is there really nothing that can be done?! Li Yi asked with a gloomy face.

Li Yan, Tong Fei, Yan Lei, Qiao Xuan...... In just 28 years, Li Yi has sent away several relatives and teachers, and years of war have made Li Yi accustomed to life and death. But every time he came to such a time, he still felt panicked in his heart, because every time he came to this time, he felt a deep sense of powerlessness when he watched his beloved teacher and elders leave.

"Lord, Duke Lu's illness is because of various dark diseases in the early years...... And Gong Lu is also getting older......" Hua Tuo said with a sigh. Hua Tuo and Zhang Ji are doctors, but their feelings in this situation are not much better than Li Yi's. It's just that their sense of powerlessness is because they are completely helpless in the face of patients.

"Alas......" Hearing Hua Tuo's words, the thousand words in Li Yi's heart finally turned into a silent sigh. waved his hand and motioned for Hua Tuo and the others to leave, and Li Yi slowly walked into the room. At this time in the house, Lu Zhi's youngest son, Lu Yu, who was only nine years old, was resting on the side of the bed. His eyes were red and swollen, and his face still had tears that had not yet dried up, and it was clear that he had been hit hard.

"Zikang, you're here~" Seeing Li Yi walk in, Lu Zhi's somewhat pale face showed a hint of ruddy.

"Zi Gangong, just now Yi has already asked Yuan Hao and the two, they said that as long as Zi Gangong takes care of ...... well" Li Yi heard this, walked quickly to the side of the bed and whispered relief.

"Hah...... Cough...... cough ......" Hearing Li Yi's words, Lu Zhi seemed to want to laugh, but just before he made a sound, he couldn't help coughing. Fortunately, soon Lu Zhi stopped coughing and looked at Li Yi and smiled, "Zikang doesn't need to comfort me, don't I know my own body yet?" ”

As he spoke, seeing that Li Yi seemed to want to say something more, Lu Zhi smiled again, "And I am already fifty-three this year, and I have experienced so many ups and downs, but it is not in vain." Birth, old age, sickness and death, who can hide from it? I'm already lucky. ”

"Zigan Gong......" Hearing Lu Zhi's words, Li Yi muttered in a sad tone. He wanted to say something, but a thousand words came to his lips, but he couldn't say a single one. Perhaps, he also knows that no matter what he says at this time, it is useless, right?

"Speaking of which, life still flies so fast. The days when I first saw Zikang in the past seemed to happen yesterday......" Lu Zhi suddenly sighed and said.

"It's still thanks to Zi Gangong's promotion, otherwise Yi would not have achieved today's achievements." Li Yi said respectfully when he heard this, and then changed his words, and assured with a serious expression, "In addition, please rest assured that Yihui will treat Ah Yu as his own son, and will definitely not let him suffer any loss!" And the Lu family will only become more and more prosperous! ”

"Hehe, with Zikang's words, I don't have any scruples." Lu Zhi smiled when he heard this, and after speaking, a trace of self-deprecation suddenly appeared on his face, "In the past, I used to be clothed, and the general Dou Wu asked him not to knight his clansmen, but now I am ...... for my son and family."

Hearing this, Li Yi naturally persuaded again and again, and he didn't know how long it took, until Lu Yu woke up, Li Yi got up and said goodbye. Because he knew that Lu Zhi must still have a lot to say to Lu Yu.

Leaving the Lu Mansion, Li Yi walked in a trance on the street, and after a long time, Li Yi came back to his senses, looked around, and suddenly laughed at himself, "I actually came here...... but I came to the door of the medical school.

Walking in, Li Yi saw a group of teenagers identifying various medicinal materials under the guidance of a doctor. Seeing Li Yi, everyone got up one after another to salute, and then went about their own things.

"I've seen the lord." Hua Tuo and Zhang Ji, who rushed to hear the news, welcomed Li Yi into the hall, and then Hua Tuo said, "Lord, Lu Gong's illness ......" Obviously, Hua Tuo thought that Li Yi was still not giving up, and wanted Hua Tuo to think of a way again.

"Don't talk about it." Li Yi directly interrupted Hua Tuo's words when he heard this, and immediately chatted with the two of them about various things about medical school.

"My lord, the hospitals in various places have begun to prepare, and I believe that it will not be long before there will be at least one doctor in each county who is sufficient to treat most patients." Hua Tuo said respectfully.

When he said this, Hua Tuo's tone was full of excitement, even Zhang Ji on the side. It's no wonder that when they studied medicine in the past, in addition to wanting to let the people around them no longer die of illness, they wanted to do something for the people of the world. It is precisely because of this that they immediately agreed to stay after hearing Li Yi's idea of medical school.

As Li Yi said, how many people can they treat alone? And now, Li Yi's former ideas are about to turn into reality, although it is only Li Yi's territory, but as long as it continues, they believe that it will not be long before the hospital can be opened all over the world.

In this regard, Li Yi was not too excited, after all, there are two gods such as Hua Tuo and Zhang Ji, and he has invested so many manpower, material and financial resources, and the appearance of the hospital is just a matter of time. And at this time, he couldn't get excited at all.

chatting and chatting, the three of them talked about medical skills, but Li Yi also knew a lot about medical skills, after all, because of Li Yan's death before, he had collected a lot of medical skills. However, that bit of medical skills is obviously not enough to discuss anything with Hua Tuo and the others, so Li Yi said more, but it is still about the medicine of later generations, in short, modern medicine.

Of course, Li Yi doesn't know much about modern medicine, and the only thing he knows may be that he needs to take medicine when he is sick, and if the medicine doesn't work, he goes to the hospital to see a doctor. But after all, he is living in an era of information explosion, and a lot of shallow knowledge in later generations is like a book from heaven in this era.

Blood transfusions, dissection of the human body and study of the disease...... Li Yi said what he knew in very shallow words. He naturally knew that with these alone, it was impossible for his current medical skills to make any rapid progress. After all, modern medical technology is not only the progress of medical technology, but also the cooperation of industry.

What Li Yi wants to do is to lead Hua Tuo and Zhang Ji, the two medical masters, to the door of modern medicine, as for how to open this door and whether they can climb the seemingly unattainable ladder, it is a matter for the two of them.

What made Li Yi very pleased was that many of his words brought Hua Tuo and the others not shock or unacceptable, but all kinds of contemplation and countless rhetorical questions. In this way, Li Yi stayed in the medical school until dusk, and then left with the reluctance of Hua Tuo and Zhang Ji to say goodbye.

"Lu Gong's condition ......" Seeing Li Yi come back, Cai Yan asked with some concern.

"Alas, who can escape from birth, old age, sickness and death?" Li Yi shook his head and sighed when he heard this.

Hearing this, Cai Yan just wanted to open his mouth to be relieved, but Li Yi strode into the house with him in his arms, and smiled at Cai Yan at the same time, "So, you have to cherish the present even more~"

"Hehe, it's better to let Qing'er and the others come together, otherwise Yan'er won't be able to withstand the gentleman's favor~" Hearing this, Cai Yanjiao smiled, with a hint of teasing and temptation in her tone. Because she knew that what Li Yi needed at this time was not comfort, but venting......

A few days later, Lu Zhi, a great Confucian and famous general, died of illness at the age of 53......
