Li You said: "Father, it's not really that there is nothing in the air, but there is gas in the air, but people usually can't see it.

We can smell smells, and sometimes we can see, for example, wolf smoke.

Since there is air, it has power, such as the wind being able to roll the flag. Wind is formed by the movement of air, and the power of hurricanes to destroy houses and uproot trees shows its power.

Air is always around us, but it exists in all directions, and its effect on the human body is balanced, so we don't feel its pressure.

When the cup is filled with water, the air inside is squeezed out, and the pressure of the air acts on the top of the hard yellow paper, where the force is greater than the weight of the water in the cup, so the water will not fall. ”

Li Tai was really smart, he said: "I understand, the Tubo people poured half a cup of water into the cup, and there was still air in it, and the pressure of the air was still balanced, so they couldn't keep the water."

So you fill the cup with water, so that the pressure of the air is pressed on top of the hard yellow paper, so that the water in the cup does not fall. ”

Li You praised: "Yes, the fourth brother is really smart." That's it. ”

"I see." There was a burst of admiration from the crowd.

Xiao Qian said: "It seems that there is learning everywhere in life, not just in books. These studies may seem inconspicuous, but they can make a big difference at critical moments. ”

Xiao Wanyu glanced at Murong Ling, and in order to show her closeness to Li You, she said, "His Royal Highness King Qi is really knowledgeable. The slave family had learned a lot from him before. ”

Sure enough, Murong Ling was unhappy, she had already found that there was some ambiguity between Li You and Xiao Wanyu, and it was really so.

Li You was very happy to be praised by the beauty, and he said modestly: "Don't dare to be, the people take food as the sky, as long as everything is from the perspective of eating, things will be easy to do." As soon as you eat it, you will be refreshed. ”

Li Tai saw him and said sarcastically: "Does the pressure of this air have anything to do with eating?" ”

Li You smiled: "The relationship is big." Let me tell you, the most basic quality of a foodie is not to eat, but first to smell, to have a good sense of smell. And the smell of food is first and foremost airborne......"

When it came to eating, Li You's eyebrows suddenly fluttered.

……

Honglu Temple Guest House.

When the Tibetan delegation returned to the guest house, they were all in a state of despair, and Grobby said: "I saw that things were about to succeed, but in the end they failed. I'm really unwilling. ”

Lu Dongzan was very calm and said, "What if you are unwilling? The prosperity of Chang'an and the profound culture of the Tang Dynasty are indeed beyond our ability to catch up with Tibet.

For the sake of today, I can only work hard to learn Sinology culture in Chang'an, and spread the knowledge here to Tibet, and it is not in vain to come all the way. ”

Grobby said helplessly: "That's all there is to it, let's go back first." You write a letter to your family, and I'll take it back for you. ”

Murong Yege, the leader of the killers, finally grasped Murong Ling's accurate information and immediately launched an operation.

In the Liangyi Palace, Li Shimin asked, "How is this Lu Dongzan placed?" ”

Li You said: "Lu Dongzan is too smart, and the advanced knowledge of our Datang cannot be passed on to him.

Erchen suggested that he should study the Five Classics in Chang'an and educate him with the teachings of the sages.

The fourth brother's literature museum is dedicated to studying the doctrine of the sage, so let him go to the literature museum and accept the sage's ideological edification. ”

Li Tai was unhappy when he thought of Lu Dongzan, he was slapped in the face, how embarrassing it would be if they met every day.

He quit and said, "This Lu Dongzan is not recruited by you, it is better to follow you." ”

As soon as his words came out, he suddenly felt that something was wrong. This Lu Dongzan was not only recruited by Li You, but also deceived by Li Shimin and them together, and even Empress Changsun also participated.

Sure enough, Li Shimin was a little unhappy, and his brows furrowed.

The eldest grandson Wuji said: "The minister agrees with the opinion of His Royal Highness the King of Qi, although Lu Dongzan is smart, but after all, he was born in a barbaric place like Tubo, and what he lacks is the education of the saints

His Royal Highness King Wei's Literature Hall is all the children of saints, and they can completely help Lu Dongzan improve his cultivation. ”

Xiao Qian supports Li Tai, but he already regards Li You as his grandson-in-law in his heart, and this relationship is far and near, and the importance is naturally clear.

He said: "The minister thinks that His Royal Highness the King of Qi's opinion is more appropriate, and my Tang Dynasty's knowledge of Gewu cannot be taught to Lu Dongzan, such as the method of making salt, as well as the method of making sugar, etc., these techniques must be kept secret."

The doctrine of the sage is different, it is originally to educate the people of the world, especially the people of Fanbang, and it should be strengthened.

Therefore, the minister agreed with the opinions of His Royal Highness King Qi and Lord Changsun. ”

Li Shimin nodded and said, "That's right, that's it, Li Tai, Lu Dongzan will stay in the literature hall inside." Take good care of him in life, and don't let the Tubo people say that our Datang has treated their people badly. ”

"The retainers obey." Li Tai reluctantly agreed.

Li You said: "Father, don't you like Lu Dongzan very much, and you want to make him the general of the right guard?" ”

Li Shimin said with a smile: "Yes, Lu Dongzan is a talent, I like it very much, so I will make him the general of the right guard." "The Great General of the Right Guard is a loose officer.

Eldest Sun Wuji and Xiao Qian both laughed.

Li Taixin said: "These people are really yin enough, if this news is transmitted back to Tubo, will Lu Dongzan still be able to say it clearly?" ”

……

Li You and the others left the Liangyi Palace, Murong Ling and Li You walked together, and deliberately said in a very low voice, but Xiao Wanyu, who was following behind, said: "Husband, for you, I have worked hard, after I go back, you have to cook yourself and treat me well." ”

When it came to eating, Li You suddenly became energetic, he said: "Wife, I haven't cooked for a few days, and it's just itchy, I'll go back today and I'll make you your famous dish of Tuyuhun roasted sea bass with garlic." ”

Although Xiao Wanyu knew that they were pretending to be husband and wife, she was still very sad to see the two so close, and tears rolled in her eyes.

Out of the Vermilion Bird Gate, Li You said goodbye to Xiao Qian and Xiao Wanyu, and got into the carriage with Murong Ling and left.

Xiao Wanyu looked at the carriage in the distance, and tears finally fell.

Xiao Qian didn't say a word, gently grabbed her shoulders, and walked towards the carriage.

Qi Wangfu.

"Uncle Guo, you're here." The guards guarding the gate, seeing Yin Hongji, stepped forward to take the reins of the horse in his hand and greeted.

"Is your prince back?" Yin Hongji asked.

"Not yet, but it's almost noon, and the prince should be hungry." Everyone in the Qi Palace's Mansion knows that being hungry is a big thing for the prince.

Yin Hongzhi said: "Bring me a chair, it's a good day, I'll wait for him here." ”

Soon, Changshi Tianmin, who heard the news, also sat at the door and chatted with him.

On Suzaku Street, a convoy of carriages and horses is moving.

On the carriage, Murong Ling asked, "Li You, what does that Xiao Wanyu have to do with you?" ”
