After dinner and chatting for a while, Qin Yu returned to his room, closed the door, sat on the bed and pondered for a while, then sighed and took out the hidden treasure chest.

The things in the treasure chest were brought by Qin Yu from modern times, and there were more than a dozen pieces of scientific and technological knowledge copied from mobile phone documents, if it wasn't for the boring at the beginning, and he wanted to write a novel and play time, Qin Yu would not have searched for information and downloaded it, but at this moment Qin Yu admired his foresight very much, no, I used it.

Of course, this knowledge is not detailed, otherwise Qin Yu would have developed in an all-round way a long time ago, but it is enough to deal with Li Shimin at this moment.

Empress Changsun has asthma, the cause of which Qin Yu is not very clear, but it is likely to have something to do with her giving birth to a child too early and contracting a cold, so that it was later passed on to Li Lizhi and the little son, as for who else, Qin Yu can't remember clearly.

There are many types of asthma, complex etiologies, allergies, congenital, etc., and in modern times, I have only heard of control, and I have never heard of completely eradicating it.

There are a lot of home remedies circulating on the Internet, saying that this is useful, that is useful, and there is no way to determine whether it is true or false, but it can more or less suppress cough and relieve asthma, after all, there are some ingredients in it that have this effect, of course, modern people rarely believe in these home remedies, and they can be solved by going to the hospital, so why believe in what home remedies.

But this is the Tang Dynasty, there is no Western medicine and Chinese patent medicine for people here, Qin Yu can only rely on the so-called home remedies, fortunately, this home remedies can indeed play a role in inhibiting and relieving, otherwise Qin Yu will inevitably stick to the end at that time and never let go.

After carefully recalling the symptoms of Empress Eldest Sun that Li Shimin said, Qin Yu chose a suitable home remedy and copied it down.

Of course, these are not enough, in order to prevent the recurrence of the eldest grandson queen, the places that should be paid attention to in life and diet, Qin Yu also explained one by one, for example, pears should be eaten often, which can play a role in preventive care, of course, it should be boiled in water.

As for Li Lizhen, history records that she has asthma inherited from Empress Changsun, but Li Lizhen didn't say it that day, and Li Shimin didn't say it, Qin Yu felt that Li Lizhen hadn't had asthma at the moment, and if the inference was true, then Li Lizhen might also have asthma caused by giving birth prematurely.

No matter what the reason is, Qin Yu also explained in the letter, asking Li Lizhi to pay attention to her diet and eat less raw, cold, greasy and irritating foods.

Since Li Lizhi will become Qin Yu's wife in the near future, Qin Yu naturally wants to make Li Lizhi healthy and healthy, since there has been no asthma now, it is good to prevent it, maybe there will be no one in the future.

After writing the letter and checking it three times, and there were no mistakes or omissions, Qin Yu breathed a long sigh of relief, and then lay down on the bed to sleep.

There is nothing else to do if you don't sleep, no women, no computers, no music movies, nothing, what do you do without sleeping, count the stars? Qin Yu didn't hurt so much.

The next day, Qin Yu got up, hastily ate breakfast and went to Chang'an with the stones, the letter had to be handed over to Qin Qiong, and he sent it to Li Shimin, Qin Yu had no right to enter the palace, although he could call the palace maid or something, but Qin Yu really didn't have the heart to take a day trip to the palace.

Who knows, as soon as Qin Yu came to the bottom of the mountain, he saw a man with bloodshot eyes and a beard, it seemed that he hadn't slept for a long time, his face was decadent, and after being slightly stunned, Qin Yu suddenly realized that this was not who Changsun Chong was.

"Qin Yunfei! You're a villain. When the eldest grandson Chong saw Qin Yu coming down the mountain, he suddenly came to his senses, his eyes erupted with fire, his anger was high, he raised his hand and pointed at Qin Yu, and scolded as soon as he opened his mouth.

"Ah, who is the demon who dares to insult the young master of my family and eat me with a hammer." When the stone heard this, he was immediately angry, and with a loud shout, the big hammer was raised, and when Qin Yu saw this, he hurriedly pulled it, "It's okay, didn't you see him alone, what are you making a fuss about." ”。

The stone felt that what Qin Yu said was right, and nodded in agreement, but the sound of the stone came from Qin Yu's mouth.

Anyway, last night, Qin Yu and others chatted, Cheng Huailiang said that a man who loves to rub fat and powder, walking and twisting, Qin Yu came up with a sentence, where is the demon, was heard by the stone, I felt that this was imposing, so I kept it in my heart, this is not a sentence today.

Qin Yu stepped forward with a smile, clenched his fists, and shouted, "Brother Eldest Sun, don't come unharmed." ”。

Changsun Chong came with anger, obviously he already knew about Qin Yu and Li Liqian, which could be seen from his haggard appearance, but the anger just now was stiffly suppressed by the loud shout of the stone, and it was only then that Changsun Chong noticed the stone behind Qin Yu.

The pair of terrifying sledgehammers startled Changsun Chong when they landed, swallowed his saliva, and Changsun Chong snorted coldly, "Hmph." Obviously, the eldest grandson Chong didn't accept Qin Yu's love.

"Qin Yunfei, I treat you as a brother in vain, why do you want to rob my cousin? If you don't make it clear today, you won't want to leave. Changsun Chong's emotions were very excited, and his body kept shaking when he spoke.

Qin Yu shook his head helplessly, thinking, "At that time, the knife was on Lao Tzu's neck, can I disagree, you and I are willing to marry your cousin, damn, well, no, if you remove her princess identity, it's not impossible, the little girl is still quite smart, but your sister, when will I become your brother." ”。

Qin Yu sighed after thinking about it, and said, "Brother Eldest Sun, things are not what you think, how to say it, well, you and the princess are indeed close relatives, this close relative cannot be married, otherwise the offspring will not be good, can you check this point yourself, and then you will know whether Qin is lying or not." ”。

Where would the eldest grandson know how to believe, and just as he was about to open his mouth to scold angrily, he was instantly blocked back by Qin Yu.

"And.".

"Although this marriage is said to be the order of the parents and the words of the matchmaker, two people have to like each other, otherwise what is the meaning of getting married, the hearts are not together, is there still happiness in this day, I have said so much, doesn't the eldest grandson still understand?".

"You!" Changsun Chong pointed at Qin Yu tremblingly, speechless angrily, and wanted to refute, but what Qin Yu said was indeed reasonable, and the fact is also true, Li Lizhi didn't like him, at this moment, Changsun Chong's head drooped down, his momentum was completely lost, and his face was decadent.

It is said that after Changsun Chong got the news yesterday, he went to the palace to ask Empress Changsun as soon as possible, how could Empress Changsun tell the actual situation, just that the two of them were not suitable.

In desperation, the eldest grandson Chong went to Li Lizhen again, thinking that Li Lizhen was being persecuted, and even thought about it, as long as Li Lizhen agreed, he would elope with her.

It's a pity that a warm blood is exchanged for a basin of cold water, Li Li's direct words will not hit Changsun Chong lightly, otherwise, no matter what Qin Yu says, Changsun Chong will also fight back.

In the end, Changsun Chong's words asking Qin Yu to give up Li Lizhi couldn't be said, so he stayed there like a fool, and at this moment, Changsun Chong was disheartened.

Qin Yu sighed secretly, came to Changsun Chong's side, patted Changsun Chong's shoulder, and said earnestly, "Brother Changsun, there is no grass at the end of the world, why bother to love a flower, Qin has always believed that men and women must be happy with each other in order to be happy." ”。

"I want to be in the Tang Dynasty, outstanding people, more than tens of millions of beauties, eldest grandson, I want to know more, for example, Hedong Pei's family, there are abundant beauties, which one is not the national color and fragrance, if Qin Mou has a marriage contract, Qin Mou also wants to go to find one or two.".

Eldest Sun Chong was silent for a while, then looked up at the sky, sighed, and looked at Qin Yu after a while, but this look was a little strange, only to hear Eldest Sun Chong say, "Why do I listen to your words so much like the old bustard in the Qinglou?" ”。

Qin Yu's face suddenly froze, "Your sister." ”。

"Cut, you're going to marry my cousin, and you still want to beat my sister's idea, don't even think about it." The eldest grandson spat on the ground, glanced at Qin Yu with disdain, and then waved his sleeves, got on his horse and whipped away.

"Damn." Qin Yu looked at the back of the eldest grandson Chong and raised his middle finger fiercely.

Qin Yu stood in place for a while, then smiled and said, "Go." ”。

Qin Yu came to Qin's mansion, and after seeing Qin Qiong, he handed the letter to Qin Qiong, Qin Qiong knew the seriousness of the matter, inquired, and after getting Qin Yu's affirmative answer, he immediately set off to the palace and handed over the letter written by Qin Yu to Li Shimin.

After Li Shimin saw the letter written by Qin Yu, he was suddenly stunned, but many of the foods that Qin Yu wrote in the letter to avoid eating were eaten by Empress Changsun on weekdays, and he immediately regretted it greatly.

Li Shimin showed Qin Yu's recipe to the imperial doctor, where did the imperial doctor know what this recipe was for, and there were not many medicinal materials in it, but one or two, and the rest were either melons and fruits or honey, and from the looks of it, he couldn't come to a conclusion.

Li Shimin was immediately furious, of course, not to Qin Yu, but to the imperial doctors, but fortunately, Empress Changsun stopped them in time, and these imperial doctors were spared.

Empress Eldest Sun took Qin Yu's letter and read it for a while, then suddenly smiled, "This son is also considerate, Bixia, there is no need to verify it, just follow this son's recipe." ”。

Li Shimin frowned, nodded, and then instructed the imperial doctor to make a decoction according to the recipe.

When the decoction was boiled, Li Shimin naturally did not ask Empress Changsun to drink it first, but found someone to try it first and confirmed that it was non-toxic, so he asked Empress Changsun to drink it.

Although it was not immediate, when she slept at night, Empress Changsun did sleep a lot sweeter than before, her chest tightness was greatly improved, and her breathing was much more comfortable.

Li Shimin was overjoyed when he saw this, but the letter written by Qin Yu came to Princess Changle at the moment, after all, some of the words in it were written to Princess Changle, after reading Qin Yu's letter, Princess Changle was excited and didn't sleep all night.
