Finding a piece of ice in the middle of winter couldn't be easier.

The students in the second class were a little excited, stepping on the snow and following Li Chuan to see how he made fire in the ice.

If others said this, they would have been ridiculed by them to doubt life, but Li Chuan was different, although everyone did not believe it all, they believed at least half of it.

The remaining half depends on whether Li Chuan can really take out the fire.

In fact, it is not difficult, to find a piece of ice with a suitable shape, Li Chuan looked up at the sun, today's sun is not bad, although it is afternoon, the sun is also working dutifully.

The students gathered in a circle, surrounding Li Chuan in the middle, squatting in the front row and standing in the back row, making sure that everyone could see Li Chuan's movements clearly.

Then they saw that the paper that Li Chuan put on the snow was really slowly burning, and the top of the paper was the ice cube that Li Chuan was holding and polished into a strange shape.

Everyone was dumbfounded, although they were all mentally prepared for Li Chuan to succeed, but this scene happened in front of their eyes, which still caught them off guard.

When they raised their heads to look at Li Chuan again, their eyes were like looking at immortals.

Li Chuandu was not only fluttering for a moment, but then he straightened his face and shouted: "What are you looking at, don't you do the experiment yet?" Didn't you see what I just did? Now it's your turn. ”

The students are a little confused, do they do it? Can they also make fire in ice? Isn't that something that only gods can do?

"Hurry up, do it, and when we succeed, let's go into the house and talk about theories." Li Chuan stuffed his cold red hand into his clothes to warm up.

Everyone looked at each other and began to look around for ice, and after half an hour, someone finally succeeded, shouting excitedly as if they had won a five-million lottery.

Li Chuan rubbed his ears, waited for a while, and after seeing that about a dozen people had succeeded, he clapped his hands and attracted everyone's attention, "Do you want to know why you can make fire in the ice?" ”

"Yes!" It's so much to think about, okay?

"Let's go, go back to the classroom, and the teacher will teach you well." Li Chuan waved his hand and led the students back to the classroom.

He didn't know that his set of sassy operations directly made the classmates in the first class lose their minds to practice calligraphy, and secretly poked and poked on the window and watched for a long time, shouting and screaming for a while, wishing that he could also go down to participate.

Xu Jingzong, who watched the students practice calligraphy, didn't know what expression to make, Li Chuan's operation of making fire in the ice, he also saw it for the first time, let alone the students, even he wanted to know what was going on.

Very good, Li Chuan's purpose of mobilizing students' interest has been fully achieved.

After returning to the class, I suddenly found that there was a Xu Jingzong sitting at the back of the class, and all the students in the first class were standing in the corridor and couldn't enter the classroom, and they couldn't listen in the corridor?!

Li Chuan was speechless, thought about it, didn't care about them, just went to class step by step.

What kind of light and heat problems, the principle of refraction of light, and prism or something, anyway, Li Chuan said a lot, but the students didn't understand it.

But it doesn't matter, it's just the beginning, take your time, tomorrow he will start laying the foundation for the students, and he will always understand it in the future.

The first day of class was very pleasant, and Li Chuan was in a good mood, but he didn't know that after these students went home, they demonstrated to their families how to make fire in the ice, and then those family members, including the court officials, were also confused.

Can my son be so godlike on the first day of class? What kind of fairy classroom is this? Specializing in teaching people to be immortals?!

As a result, many ministers studied the ice cubes in their homes for an entire night, as if there was some unknown magic in that small ice cube.

Among them, Li Shimin, the emperor, will only pay more attention to Li Chuan's movements than others, and he will know the information earlier, but he has been playing with the ice cubes for a few hours, and his hands are frozen red, and he has not studied what is special about this ice cube.

The sons were still young, they were all in the first class, and they did not participate in the experiment in the second class, so he could only find Li Chongyi and ask him to do the experiment again in front of him.

As a result, because it was night, the experiment was not successful.

Li Chongyi looked helpless and not very good, and said: "Your Majesty, the teacher said that the ice cube is just a medium, and it is the heat of the sun that really works. ”

Li Shimin's face was serious, "The heat of the sun is not so great, this is winter." ”

"It's the sun's heat concentrated at one point, it's hot." True, someone's fingers were burned.

There is no shortage of people to die at any time, and it is not him anyway.

Li Shimin pondered for a while, and then asked, "What is a medium?" And why did you make the ice cubes this shape? ”

Li Chongyi was silent, carefully recalling Li Chuan's words, "This shape is to better concentrate the heat of the sun, as for the medium, he did not explain. ”

He probably understood the meaning in his heart, but he couldn't say it, because he wasn't sure that what he thought was necessarily right, what if it was wrong? If someone else asks, they will say it, but it is the emperor in front of him, and he can't talk nonsense.

Obviously, Li Shimin doesn't need to listen to him, he has his own understanding.

Putting the person home, he took the ice cube that Li Chongyi grinded out and studied it again, wrote down the shape, and planned to try it again tomorrow during the day.

Li Chuan routinely knocked on the ink lotus every night, and sent his latest boastful statement, he didn't expect that there would be movement on the ink lotus's side, after all, it had been so many days.

He just sighed that a woman's temperament is really big, so he was right not to talk about his girlfriend before.

Thank God I didn't think about it, and at the same time, I also thanked Li Er for solving the problem of his future wife, which was really worry-free.

As soon as the video connection was opened, the first thing Li Chuan saw was the background behind Mo Lotus.

It was a beach, the sun was shining, the water was blue, and in the sun, by the water, there were countless bikini beauties laughing and playing, and at the same time, there were countless stinky men on the side.

[How?] Like the background? Mo Lianhua stroked her long wavy hair, turned her head to look back, and then turned back to look at Li Chuan with a smile.

Li Chuan pondered for a long time and said, "Compared with them, you are wearing too much." ”

[Nonsense, think the old lady will give you this kind of benefit? ] Dream on! Mo Lianhua stared, she was also wearing a bikini, but there was also a shirt on the outside, which was faintly and half-transparent.

Li Chuan really wanted to tell her that it was more eye-catching to wear like this, but after thinking about it, it was better to do it, so as not to say too much and make too many mistakes.

"Cough, what's that, you haven't confiscated the gifts from the last transaction, that, I prepared a pair of calligraphy and paintings, written by Li Shimin, and he is also an emperor anyway, give me a face." Li Chuan touched his nose and said with some embarrassment.

It's obviously all good words, but I don't know why he just feels embarrassed when he smiles at the ink lotus, as if he can see through everything.

[Okay, it seems that I have little energy when I deal with you. Mo Lianhua accepted the calligraphy and painting without any opinion, and then said: [You look at the background quickly, I will be separated from this world in a few days, and I don't know what kind of world I want. 】

"Huh? So fast? ”

[A year is up, and the task has already been completed, I've been on vacation for half a year, and I've been doing nothing, and it's quite boring. Mo Lianhua looked bored and stroked her hair again.

Li Chuan was silent, sure enough, Emperor Ou's world was not something he could imagine.

"So, looking forward to a new world?" Li Chuan said uncertainly.

[Hmm.] Mo Lianhua responded, turned her head to look behind her, and said, "Don't you have anything to say about the background behind? 】

Li Chuan glanced at the very eye-catching background again, and asked strangely: "Why are they all young people?" Shouldn't everyone have the beach? ”

What about children and the elderly?

[This is a private beach, it's a party now, I said, isn't your focus a little crooked?] Isn't it time to focus on beautiful women?

Li Chuan's reality performed a performance of what is called envy, jealousy, hatred!

"Private beach? It's too extravagant, it's too loser! When they play like this, don't they think about the victims who can't even eat? Can't you take the money out and do something meaningful? It's just, it's ......," Li Chuan said.

Mo Lianhua's face was black, and the corners of her mouth twitched a few times: [You just can't eat grapes and say that grapes are sour, right?!] 】

Li Chuan glanced at her expressionlessly, and his little temper also came up, and he directly cut off the video connection.

Ink Lotus: [...... Scold! 】

was hit by Emperor Ou, Li Chuan felt that only hot pot could heal his mood.

So, he secretly left the ingredients and let him eat them all.

Obviously, he still wanted to divide it into two meals, but Emperor Ou stimulated his appetite too much, so he just ate it, and the ingredients were gone.

Some sadness!

Li Chuan began to walk up and down the stairs in the villa, and it was not suitable to go out for a walk in winter, so he could only walk around at home.

While strolling around, I also thought about what I wanted to teach tomorrow.

It's just that the plan hasn't changed quickly, and before it's class time, Li Chuan received a summons from Li Shimin.

I confirmed the date, tomorrow is the time of the Great Dynasty, why do you have to look for him today?

After thinking about it, Li Chuan brought a bucket of soybean oil, which he regarded as a gift to Li Shimin.

Who knew that after meeting, Li Shimin asked: "How much do you know about such a technology as making fire in ice?" ”

Li Chuan was stunned, what does he know about it? Making fire in the ice was just a small physical experiment, and if it really did, he didn't know how many there were.

"The fire? Wash your hands with boiling oil? Or decompose the water element? Li Chuan suddenly couldn't think of much.

These are all things he plans to let the students experiment on their own in the future, and it is a little difficult to decompose the water element, so he has to buy a generator.

He is hesitating about this, 500,000 live broadcast coins are available, but after buying a generator, he will return to the pre-liberation period again, and he can only live a poor life.

"Chestnut in the fire? Wash your hands with boiling oil? What is the element of decomposition water? Li Shimin squinted and asked.

"The decomposition of the water element can't be done now, there is a lack of things, but it is very simple to take chestnuts from the fire and wash your hands with boiling oil, in fact, the flame also has to distinguish the temperature, and as long as the speed is fast enough, the flame can't hurt anyone, as long as you are prepared, boiling oil and washing hands is just a gimmick, there are many folk ...... emmm Inhuman? They will use this to deceive the people, in fact, the boiling oil is just a layer, the bottom is vinegar, the boiling point of vinegar is relatively low, it looks like the oil is boiling, bubbling, but put your hand into it, you will know, just warm, of course, even the vinegar can not be boiled for too long, otherwise it will hurt people. ”

Li Shimin nodded, and changed the topic again: "I heard that you received a doorman by your side?" ”

"Ah, yes, he helped me, and there is nowhere to go." Li Chuan was very frank, Xu Xinsheng had always wanted to do something, but Li Chuan refused on the grounds that his body had not yet recovered.

Let him be responsible for what to do in the future, Li Chuan is also thinking about it now.

"Be careful, don't let him get in the way of you." Li Shimin reminded that according to his investigation, although this Xu Xinsheng renamed himself Xinsheng, he did not let go of the past at all, and he always wanted to take revenge.

The bully who destroyed his family, as well as the local officials who sheltered the bully, were his targets.

Li Chuan looked dazed, and didn't understand what Li Shimin meant.

Li Shimin sighed, thinking to himself, forget it, he doesn't need to do anything about such a trivial matter, just arrange someone to do it, and he is not afraid of Xu Xinsheng doing anything.

"The people around you, pay attention to the investigation, don't accept everyone around you."

Li Chuan nodded, he knew that there were more people who made his own ideas, and he had paid attention to this aspect.

"That, Your Majesty, the minister brought a kind of oil, why don't you use it to stir-fry at noon and taste it?" Li Chuan motioned to the little eunuch next to him to bring up the oil he brought.

Wang Dehai nodded slightly, and the little eunuch acted, which made Li Chuan extremely emotional.

Either it is said that the chief eunuch can be half of the emperor's family, this is not false.

"What oil?" Li Shimin instinctively asked, only to suddenly remember what someone reported to him a few days ago, "Just the oil from the oil mill built in your village?" ”

"Yes, Your Majesty, this is vegetable oil, which is good for the body, and it is healthier than lard. Li Chuan is very serious about popularizing health knowledge for Li Shimin.

In the end, Li Shimin only came to one conclusion, eating lard will clog blood vessels, causing people to have a stroke and be paralyzed, so it is better to eat vegetable oil.

He really knew that some people would suddenly have a stroke when they were short of breath or ecstasy, and he understood that the word stroke was an external wind evil, which would cause people to have a stiff face, tremble hands and feet, and basically lose their mobility.

In this way, he really needs to change the oil!

Li Shimin has always paid great attention to his health, and since he wants to change the oil, he must change it thoroughly.

"Send fifty barrels of oil into the palace every month, the price, according to the current price of lard." If Li Shimin looked at Li Chuan meaningfully, the price was quite high, which was considered a benefit he gave to Li Chuan.

But Li Chuan couldn't appreciate it, he had a bitter face, "Your Majesty, fifty barrels a month?" You think too highly of Wechen's oil mill, and being able to produce five barrels a month is already considered a high yield. ”

Using the bucket meter, Li Chuan knows how big the barrel of the Tang Dynasty was.

And even if the oil mill can produce it, the raw materials are not enough!
