In September 629, Xia Xue was pregnant, and Li Shimin was happy all day long. Xia Xue, as a human being in the future era, is not like the "menstruation" of human women in the past, who ovulates every month and has a period; Human women in the future era will only ovulate and have a period every year, which is called: "annual period", and Xia Xue's "annual period" is generally in September every year, so she will get pregnant in September.

After being pregnant, Xia Xue knew that raising a fetus was very important to the child, so she basically didn't do any research experiments during pregnancy, mainly to rest and recuperate, and she should give herself annual leave. Except for some major things, I don't participate much in the basic daily work, I just walk around the beautiful scenery and fresh air all day long, and the diet is adjusted according to my own requirements, of course, to ensure nutrition first.

10 months later, in the palace of Chang'an.

Xia Xue felt a little pain in her lower abdomen, and the pain at this time was bursts and bursts, once every ten minutes. She knew that she was about to give birth, so she hurriedly called the midwives and palace maids who had been waiting outside for a long time to come in.

Li Shimin heard Xia Xue's pain, and anxiously wanted to go in, but was stopped by the palace maid, the ancients were superstitious, and men were not allowed to enter the delivery room.

The frequency of pain is getting higher and higher, from more than ten minutes at a time to about five minutes at a time, the pain gradually intensifies, once every three minutes, and each time the pain lasts longer, the pain can be compared to being punched in the lower abdomen.

Then the intense pain began, at this time, the breathing could no longer relieve the pain, and the body began to sweat, and I could only endure it with willpower.

When the amniotic water broke, Xia Xue only felt "pain" in her spirit, the pain of her lower abdomen being crushed, which was a pain that could not be described in words, like waves of tide pouring in. It's like an electric drill drilling through her internal organs, the pelvic bladder is about to burst, and the painful Xia Xue keeps trembling and sweating. I couldn't help but scream loudly.

In medicine, the pain felt by humans is divided into 12 levels, and the higher the level, the greater the pain felt. The first level is a mosquito bite, which is almost imperceptible; The ninth level is the tiger chair, the pain of flesh and skin caused by the ten tortures of the Manchu Dynasty, such as tying bamboo sticks; Grade 12 is the pain during childbirth.

The human body can only withstand a maximum of 45 (units) of pain. But during childbirth, a woman suffers as much as 57 (units). This pain is equivalent to 20 bones broken at the same time!

Xia Xue was about to faint in pain, and said hatefully in her heart: "I will never have children again, don't let me die again." But in fact, for the sake of the future of the Tang Dynasty and her love for Li Shimin, the queen who cherished the overall situation later endured the inhuman pain of 4 births and gave birth to a total of 5 children to Li Shimin. Originally, because she only had her "annual period" in September every year, it was very easy to avoid clouds and not have children, but she still chose to take care of the overall situation and choose to bear the pain without hesitation. It has to make people respect the queen again.

Li Shimin listened to Xia Xue's heart-rending SY outside, his heart seemed to have been cut by a needle bayonet, and he was also distressed.

Due to traditional restrictions, he couldn't enter the delivery room because his heart was like a knife, so Li Shimin, who was very anxious, ran to the outside of the delivery room, knelt on the ground, and kowtowed to the sky three times in a row, his forehead had been broken and bleeding, he cried and prayed loudly: "God, please transfer all Xue'er's pain to me, I can't let her suffer anymore!" If she has any accidents, I won't survive! - Oh my God! Please! ——”

When the attendants and ministers outside saw the emperor crying and worshipping heaven and earth, they all knelt on the ground and prayed loudly to the sky: "I ask the heavens to let the eldest grandson queen no longer suffer, and let the little prince be born quickly and smoothly!" ——”

Throughout the palace and outside, there was a thunderous prayer, and the sound shook the sky.

Perhaps it was the sincerity of the Tang Emperor and his subjects that moved the heavens, praying for a quarter of an hour.

"Wow-" With the cry of a baby, on June 12, 630 A.D. (3:20 p.m.), Xia Xue gave birth to a healthy and lovely little prince.

Li Shimin looked very handsome and looked like his son, his happy mouth couldn't close, and he couldn't put it down in his arms. But when I saw Xia Xue, who was covered in sweat and in a coma in pain, my heart was like a knife, and I burst into tears.

The ministers saw that the Tang Dynasty finally had the crown prince and the crown prince, and a heart that had been hanging was finally let go. In the traditional concept of ancient empires, an empire with a crown prince and a crown prince can be regarded as a stable inheritance and long-term stability. Therefore, the queen can give birth to a son, which is a particularly gratifying event for the ministers of the Tang Dynasty and for the common people.

For this reason, the whole country of the Tang Dynasty celebrated the birth of the crown prince for three days.

……

Of course, wanting to have a son is easy for women in the future era. They know that in the month before and in the month before their "menstruation", for example, Xia Xue's "menstruation" is in September every year, so they start to pay attention to their diet in August and September, and if they want to have a son, they should eat more alkaline foods, alkaline vegetables and alkaline fruits.

Alkaline fruits generally include: oranges, watermelons, grapes, bananas, strawberries, apples, grapefruits, lemons, pears, oranges, mangoes, hawthorns, pomegranates, lychees, peaches, etc.;

Alkaline vegetables include: tomato, black fungus, white fungus, potatoes, cauliflower, winter melon, lettuce, cucumber, carrot, kohlrabi, lotus root, radish, spinach, mushrooms, leeks, snow ferns, cabbage, bamboo shoots, lettuce, bitter gourd, rape, yams, onions, kelp, pumpkin, peppers, etc.

Alkaline drinks include: milk, honey, tea water, etc.

If you want to have a daughter, eat more acidic foods in the month before and in the month of "menstruation", acidic foods generally include: beef, mutton, pork, chicken, duck, fish, grains, egg yolks, cheese, desserts, sugar, wheat, rice, peanuts, seaweed, green onions, etc.

In addition, Xia Xue also paid special attention to one point, that is, for the health of the fetus, she asked herself and Li Shimin not to drink alcohol in the month before and in the month before her "menstruation", that is, in August and September. Li Shimin, who is a good husband and father, is naturally quite obedient in this regard, and in August and September, no matter how happy the court is and how important the banquet is, he resolutely refrains from drinking, and generally uses the excuse that he is unwell and cannot drink. Of course, not to mention Xia Xue herself, she usually doesn't like to drink, and she strictly avoids alcohol in August and September.

In order to ensure the health of children in the Angel Country, four years ago, Xia Xue set up the "Angel Vaccine Company" to develop vaccines to prevent virulent infectious diseases. Under Xia Xue's guidance, a vaccinia vaccine against smallpox has been successfully developed. Vaccinia vaccine is safe, reliable, and does not cause human-to-human transmission after vaccination, and vaccinia vaccine is still considered the best way to prevent smallpox for a long time to come. Therefore, Xia Xue decided to first develop this simple, safe and reliable vaccine to ensure the health of the children in the Angel Kingdom, and now her own baby has also benefited. After marrying Li Shimin, Datang has also become Xia Xue's motherland, and Datang's children can also be injected with the vaccine developed by the angel company. Of course, these vaccines are not provided for free, as a company, of course, it is necessary to make a profit, after Xia Xue's successful research and development, it is recommended that Li Shimin purchase special financial funds for the country's people's livelihood and welfare, of course, as a people's livelihood cause that is conducive to the health of Datang children, Xia Xue's price for the vaccine purchased by the Datang government is not very high, although there is a profit, but it is not a huge profit. But for other countries to purchase, she is opening a very high price, it is simply a huge profit, in business, not to do loss-making business, is Xia Xue's consistent principle, after all, "profit is the life of the enterprise". Xia Xue is a dedicated and pragmatic person, and she doesn't like to engage in any false fame.

Xia Xue is a principled person, principled people will not be equally fraternized, and principled people will not love everyone like pepper noodles. Xia Xue is a real person, real people have their own joys, sorrows, sorrows, and hatreds, real people will not love everyone like God, Xia Xue's love and care have always been thin and thick, she feels that this is in line with her own personality, Xia Xue's love for her family and her loved ones will definitely surpass others, her love for friends and compatriots will definitely surpass strangers and foreigners, and she will not have any love for enemies, even ruthless, this is the real and not hypocritical Xia Xue, Xia Xue likes to live a real life, never pursues hypocritical fame, and is even more unwilling to be a loving God or Mother. Although she is the Empress of the Tang Dynasty, she still acts according to her own personality, preferences and principles, never cares about the opinions of others, including the ministers of the court, and never abides by the traditional rules and constraints of the queen, such as she leads the troops to fight; For example, she started a business and started a company; For example, she often visits and plays everywhere on WeChat; For example, she doesn't read sage books, and she likes to engage in experiments with "KitKat Y skills", etc., these "willful and reckless" "anti-heaven behaviors" have never been seen among the queens of previous dynasties, and they are also the most criticized by the conservative ministers of the Tang Dynasty. Due to the prestige of Empress Changsun, her great military exploits and the incomparable favor of Emperor Li Shimin, coupled with the fact that Empress Changsun was originally the queen of the rich and powerful Angel Kingdom in the past, and the severe punishment of the officials who attacked Empress Changsun, the ministers only dared to privately discuss and complain about the unconventional "inappropriate" behavior of Empress Datang.

In fact, for the books of Confucius and Mencius and other sages, Xia Xue read them when she was in school in the future era, and the way of Confucius and Mencius, as far as individuals are concerned, is to promote and practice virtues such as benevolence, righteousness, courtesy, wisdom, and faith; For the society, it is to carry forward the virtues of Zhonghua: that is, the way of welfare, love for the people, fairness, justice, honesty, trustworthiness, reform, innovation, civilization, harmony, democracy and rule of law. Even in the future, thousands of years later, everyone will praise it. Many of these famous sayings of Confucian sages such as Confucius, Mencius, and Xunzi are actually familiar to Xia Xue and many future students, such as:

"It is better to believe in the book than to have no book.

Do unto others as you would have them do to you.

If you are a threesome, you must have my teacher, choose those who are good and follow them, and choose those who are not good and change them.

People have no foresight, but they must have near-term worries.

If you see small profits, you can't do big things.

Make friends and keep your word.

If you learn without thinking, you will be reckless, and if you think without learning, you will die.

Knowing is knowing, not knowing is not knowing, and it is wisdom.

Those who have attained the Tao have much help, and those who have lost the Tao have little help.

The rich and noble cannot be moved, the poor and the lowly cannot be moved, and the mighty cannot be bent, which is called a big husband.

If you are poor, you will be good to yourself, and if you are good, you will be good to the world.

Therefore, the heavens will descend on people, and they must first suffer their minds.

If you don't follow the rules, you don't make a circle.

Born in sorrow and died in peace.

People have nothing to do, and then they can do something.

The time is not as good as the location, and the location is not as good as the people.

The people are precious, the community is secondary, and the monarch is light.

Those who love others will always love them; Those who respect others will always respect them.

Perseverance, rotten wood does not break; Perseverance, gold and stone can be carved.

No accumulation of steps, no thousands of miles; If you don't accumulate small streams, you can't become rivers and seas.

Knowledge is infinite.

Qi Ji jumps, can't take ten steps; Ten horses, the merit is relentless. ”

Even Xia Xue, who doesn't read the books of sages now, can recite a few at will, classics are classics, it will not fade with time, but will endure.

It's just that just like the Confucian sages of Confucius and Mencius said: "It is better to believe in books than to have no books", all ancient doctrines have the limitations of the times, for Xia Xue, who has thousands of years of human wisdom and knowledge accumulation, has seen the power of nuclear weapons, spaceships in the sky, grain and vegetable factories, satellite telephones, landing on the moon, deep-sea exploration and other high-tech great achievements, of course, than those "old antique" conservatives in the Tang Dynasty who lack knowledge, stand higher and see farther. For example, the view of the power of science and technology, the view of industry and commerce, the view of the universe, the view of the monarch's law, etc., must have surpassed all the people in the Tang Dynasty, including those so-called learned masters and talented giants. Since his intelligence and knowledge far surpassed that of all the people in the Tang Dynasty, why should he act according to their narrow rules and constraints? For the sake of the secret in her heart, for the grand plan, Xia Xue still went her own way and "acted willfully". It can really be said: "not afraid of clouds to cover your eyes, you are at the top".

"Angel Vaccine Company" later successfully developed vaccines for the prevention of common pediatric diseases such as hepatitis B, polio, measles, pertussis, diphtheria, and tetanus, and also successfully developed adult injectable vaccines, such as: hepatitis B vaccine, hepatitis A vaccine, pneumonia vaccine, chickenpox vaccine, leprosy vaccine, influenza vaccine, rabies vaccine, bronchitis vaccine, encephalitis vaccine, Japanese encephalitis vaccine, typhoid vaccine, dysentery vaccine, uterine vaccine. Many vaccines, such as neck cancer vaccine and cholera vaccine, have ensured the health of countless people and saved countless lives.

Why did she name her first son Li Zhi, because she knew that it was Tang Gaozong Li Zhi who became the emperor after Li Shimin in history, and in order to prevent her sons from killing each other, she used the name of the third emperor of the Tang Dynasty in history Li Zhi as the name of her first son. When the son grows up, when choosing a concubine and a queen, as long as it is not surnamed Wu, it should be fine, and the famous empress Wu Zetian in history is after Li Zhi died, using her identity as the queen mother, step by step, and finally usurping power and sitting on the throne of the empress.

In fact, she knew that in addition to Gaozong Li Zhi, the sons born to Li Shimin and Empress Changsun recorded in the history books also included Li Chengqian, the king of Hengshan, and Li Tai, the king of Pu. Li Chengqian was the eldest and began to be named the crown prince.
