Li Xiang said to him again: "Your Highness is wrong again. The www.biquge.info ministers of the pen are not loyal to you, but for the sake of the Song Dynasty. Even if His Highness ascends the throne in the future, he cannot use ministers for personal gain, but depends on the ability of his courtiers. ”

After Zhao Ji heard this, not only was he not angry, but he said happily: "Master Li is really a good minister. ”

Since then, Zhao Ji has trusted him more and more. The two unwittingly established a relationship of mentor and friend.

Li Xiang saluted Zhao Ji, and then saluted the princess, no way, this princess also sent someone to keep an eye on her brother, once Li Xiang came, he called someone to inform her. She also came to listen to Li Xiang's lecture, and Emperor Lizong took a blind eye to her transgressive behavior. Li Xiang is not easy to say. He knew that she came to listen to him to read and listen to the story if it was true.

After Li Xiang finished saluting, he said, "Your Royal Highness Princess, Weichen has brought you a gift. ”

As he spoke, he opened the box, which contained dozens of glass balls. Among them, the largest twelve balls are the twelve zodiac cloth people. This was bought by Li Xiang after testing the composition of the glass yesterday evening, and specially asked the workers to go to the street. He also drew images from several cartoons in later generations, and asked those cloth sellers to grab them. It was also blown into the glass, and in the other glass, there were all kinds of cloth animals on the street at that time.

As soon as she saw Li Xiang holding the contents of the box in her hand, especially the cute appearance of those cartoons, the princess had never seen it at all, and her eyes immediately lit up.

She put her finger in her mouth and bit it and said, "Is it good to say that you are satisfied with this gift, or is it better that you are not satisfied with this gift?" ”

"Your Highness, why do you say that?"

"Because you say you're satisfied, you can't tell me two stories. said that he was not satisfied, and he was panicking again, and my father told me that children should not panic. ”

Li Xiang almost fainted. The heart said that fortunately, you haven't learned to panic like your brother, otherwise you will take the gift and listen to the two stories, and you will simply not do anything in the future, and slowly recall the various story books you read when you were a child in your previous life.

Finally she finally lowered her finger, and it seemed that she had a decision to make. The ministers all laughed.

She said: "Forget it, for your sake, I'll be a child who doesn't panic, and I'll let you go this time." ”

Then she attached herself to Li Xiang's ear and said, "Let me tell you, I secretly read the book "Dream of Red Mansions" you wrote. ”

Li Xiang snorted, and said in his heart that you are not too brave.

She said again: "I have made a decision, and you will be my Baoyu brother in the future." ”

Li Xiang was frightened by her words again, sat on the ground all of a sudden, threw the box in his hand, and even two glass balls fell out and shattered.

Emperor Lizong asked curiously, "Aiqing, what did the princess say to you?" ”

Li Xiang stood up with a strange look and said, "It's nothing, she said that she wanted Weichen to show her the "Dream of Red Mansions" I wrote. ”

The princess kept shaving her face with her hands, meaning that you were panicking. Li Xiangxin said, don't I panic, okay? There were so many ministers standing on the sidelines listening. Dare I tell the truth?

Those ministers all bowed their heads and chuckled, indeed, the princess was the only daughter of Emperor Lizong, and she was also the most noble girl in the entire Song Dynasty, she received a strict education since she was a child, although the book "Red Mansion" was written very well, but there were many things about men and women falling in love with each other, no wonder Li Xiang was scared like this.

Only Emperor Lizong was slightly disappointed, in fact, he guessed what his precious daughter had said to Li Xiang, and if Li Xiang really wanted to say it, he could observe the opinions of these ministers.

Li Xiang finished giving the gift and began to teach Zhao Jigewu. He first took out two flasks, one with hot water and some rouge to melt it, and one with cold water. Then he said, "Your Royal Highness the Prince, you have a good look." ”

As he spoke, he mixed the two bottles of water together, and after a while, he asked, "Your Royal Highness the Prince, what do you see?" ”

Zhao Ji said: "Lone saw two bottles of water mixed together, and even the cold water turned red. ”

Li Xiang said: "Yes, this shows that the liquid is fluid. There is another point that you didn't pay attention to, that is, at the beginning, the red water, that is, hot water, Weichen mixed the two kinds of water together, and the red hot water was on it, right? ”

Zhao Ji nodded.

Li Xiang said: "This shows that hot water is lighter than cold water, and later the temperature of the two kinds of water was transferred, and the same hot water and cold water were officially mixed together." Why this is happening. Wechen to do a two-step explanation, one is the density of the substance, the volume to weight ratio. Hot water is less dense than cold water. Second, it is thermal expansion and cold contraction. In fact, there is still so much water, but the reason why it is light is because its volume has expanded. Everything in the world has density and volumetric weight. For example, in the air, there seems to be nothing. But it is also a substance, which Wechen calls a gas. ”

When he had said this, he told the eunuch to bring a small stove and put the flask on the fire to burn. He raised a cup in his hand and said, "Actually, this kind of cup is just good-looking, and its practicality is not as practical as that of a porcelain cup, unless its cost is reduced to five times cheaper than a porcelain cup." ”

These ministers were all stunned, it was five times cheaper than a porcelain cup, it was a few copper plates, wouldn't it be a waste of treasure.

As he spoke, he asked the eunuch to bring a bucket of well water, put the cup in the well water, and chilled it for a while and took it out. Said: "Because the medicinal jade transfers heat quickly, it is fragile when it comes to teacups, especially in winter." As he spoke, he poured boiling water into the cup, and the teacup cracked. He said: "This is thermal expansion and contraction, because of its characteristics, the inside of the medicine jade expands rapidly when heated, while the outside medicine jade is still cool, which causes the teacup to break easily." ”

I understand what I heard, but these ministers are distressed, this cup is worth old money, so there is no reason to explain it. O loser! Some ministers did not know the actual cost, and even shouted in their hearts.

Li Xiang said: "When the temperature is high to a certain point, the liquid will be converted into gas. ”

At this time, the water was already boiling, Li Xiang pointed to the water vapor and said: "This water is boiling, we now know that the higher the temperature of the water, the larger the volume, but now where is the water in the bottle?" We often say that the water turns into water vapor and runs away. In fact, water is converted from liquid to gas, and the water vapor we see is caused by the fact that the water gas meets the cold air in the air and then slowly turns into a fine liquid. If the temperature is low to a certain point, it will become solid. In general, the lower the temperature, the smaller the volume, but there are a few substances that will increase. Another example is ice. We often experience water tank swelling and cracking in the winter, because the volume of ice is greater than the volume of water, and the water tank is stretched open. Your Majesty, according to this characteristic, Weichen made a thing that enables people to fly to the sky. ”

Fly into the sky? Emperor Rijong and all the ministers were stunned.

When the princess heard this, she asked, "Lord Li, is it so fun in the sky, is it different from the hours in the world?" I'm going to heaven too. ”

Li Xiang almost laughed, thinking that you are still in the sky, I see that you are almost in the ground. However, she knew that she was influenced by the influence of the Heavenly Palace, and what year it was. (To be continued.) )
