"Actually, the trick is the stuff that the kid adds to the ice." Lin Sen still hung everyone's appetite.

"What is it?" Li Shimin really asked.

"It's very simple, it's the salt we usually eat. When salt is added to the ice, the temperature becomes much lower, reaching a minimum of nearly minus 20 degrees, well, similar to the coldest temperature in northern Youzhou.

Such a cold air was blown into the house by the hand-cranked fan I made, and naturally it cooled down quickly. Lin Sen remembered that people at this time had no concept of Celsius, so he quickly changed the object of analogy.

"Then why does it get lower when you add salt? Isn't it okay to put some sugar? Does pepper get hot? The other generals couldn't help but turn into problem babies, and threw out questions one after another, which caught Lin Sen off guard.

"We all know that 'snow doesn't get cold', right?" Lin Sen hurriedly waved his hand to stop everyone's words, Nima's gang of people who came out of "One Hundred Thousand Whys" have never tried to add pepper to it, and I haven't tried it either, how do I know.

"In fact, it's the same reason as this, the snow melts away actually absorbs the surrounding heat, and then the solid snow becomes liquid water, and the ice cube is naturally the same, and it also absorbs a lot of heat before it melts away, and it absorbs the surrounding hot smell, so the ice cube will become cooler around.

If the salt wants to melt, it also needs to absorb a lot of heat, and the two of them work together to make the surroundings so cool.

As for whether it will work better with other things, I don't know, kid, I haven't tried it, you might as well go back and do an experiment. Lin Sen saw that everyone's attention was attracted, so he explained further.

"Where did the ice come from? Even if you have this method of adding salt this day, wouldn't it be useless without ice? Cheng Yanjin once again unceremoniously asked everyone's thoughts.

"The kid's family doesn't have the habit of storing ice since winter, this tulou has just been built, and there is no such thing as an ice cellar, and the kid is not so lucky to be able to encounter an ice cave that can freeze in the summer, so these ice cubes are actually made by the kid himself." Lin Sen looked at the gang of bigwigs cautiously and said.

"The kid's family is poor, and he still has to prepare a dowry of sufficient weight, so he expects this method of making ice to buy some belongings, so this method of the kid will not say anything about being killed." Lin Sen understood the eyes of these people, and clearly wanted to get to the bottom of it, so he said pitifully.

Although a group of bigwigs were a little unhappy, they didn't mean to persecute Lin Sen, and even Li Shimin didn't have the will to forcibly seize the ice-making method, if he had to take anything good for himself, then he was afraid that the world would not be stable, so in addition to feeling that this wooden boy was really a dead money, he didn't have any bad feelings.

Of course, the other generals didn't have any evil thoughts, but they were a little unhappy that Lin Sen hung their appetite like this. You can't expect Lin Sen to share anything good with them, isn't it, is it normal for people to leave some unique secrets for themselves.

"Then you kid must give priority to ensuring the supply of ice cubes in the palace in the future." After Li Shimin glanced at Lin Sen, he calmly commanded.

"As long as the capacity can keep up, this thing can still be supplied a lot, Your Majesty can rest assured." Lin Sen smiled and responded to this big business, he made it clear that he wanted to make money, Li Shimin didn't say that he would let Lin Sen do it for nothing, wouldn't there be a stable big customer.

"In that case, I can't be without ice cubes in my house." Cheng Yanjin also continued.

"Hey, it's natural." Lin Sen hurriedly assured that his father-in-law's family would naturally give priority to supply, and it was of good quality and quantity, so he couldn't be hot with his wife.

Of course, the other generals will not be left behind, and they have all set up a season's ice cube here in Lin Sen.

In my heart, I roughly estimated the supply to these people, even if I gave a friendly price, it would not be as expensive as the one sold on the market, but it was definitely a stable and huge investment, Lin Sen was naturally happy.

"You kid is waiting for us here, seeing that you are obviously making a lot of money like that." Niu Jinda couldn't help but laugh at Lin Sen.

"The kid is definitely giving a conscience price, and I don't look at the price of the ice cubes on the market, and how many of them can guarantee the supply until the dog days? This is the only one of the scorpions.

The price offered to you is half the price of the sale, and you still say so, will your conscience not be painful? Lin Sen sighed with a sad face.

"Come on, you kid just get cheap and sell well." Li Shimin glanced at Lin Sen with disdain.

"By the way, is there still that Hundred Flowers Condensation, and I don't know how to take the initiative to pay respect." Li Shimin glanced at Lin Sen again and said with a little unhappiness.

"Yes, yes, recently the mother-in-law and aunt in the family are going to go to the house to uncover the tiles, when I hear the flowers condensing the eyes, the eyeballs are green, you kid can't bear to see that I am this age, are you still living so sadly at home?" At this time, Gongsun Wuda couldn't help but pick up, but is it really good for you to expose your advantages of being afraid of your wife like this?

"Those hundred flowers condensation are all Huaiyu's, I can't make decisions for her." Lin Sen put on a posture that a dead pig was not afraid of boiling water.

Well, even the emperor couldn't help but ask for this perfume, which shows how popular this thing is now, and if we don't sell it at a sky-high price in the future, I'm sorry for your enthusiasm. But before the dowry, let these people hold back a little longer, and then they can sell even more crazy.

"I'll take the queen to choose, I just came out with one today, and the fragrance matches the noble temperament of the queen mother." Cheng Huaiyu took the initiative to take over the conversation.

Although I feel very sweet about Lin Sen's intimacy, I am also afraid that Lin Sen will leave a bad impression on the emperor, as for the relationship between her and the eldest grandson, they are very familiar with each other, and they don't have so many scruples.

"Big man, what do you want, your aunt just owes it to clean up, go back and beat her hard, see if she dares to go against the sky."

As soon as Cheng Yanjin heard that the legendary Hundred Flowers Condensation was his own daughter's, and then saw that the other old brothers were clearly interested in moving, he immediately took out the posture of hob meat and blocked Gongsun Wuda's words.

Everyone else looked at this two-skinned face with hatred, how did Lin Sen's kid look like he was beaten just now, and found the root cause from this, this is a typical crooked upper beam and crooked lower beam.

Only then did he determine how long the relationship with Cheng Yanjin had been with Weng and his son-in-law, and he learned the shameless strength of this old man, and a good honest child was ruined like this, it's a pity!

"Come on, it's not too early, it's time for a certain person to leave for Zongsheng Palace, just stay here for goodness and the little son, they are still a little weak, it's better to travel less."

Li Shimin saw that his wife, Empress Changsun, had come back with a smile accompanied by Cheng Huaiyu, and it was clear that he had found a satisfactory Baihua condensation, and this digestion was almost over, and it was time to go.

"Bring a few more chilled melons to quench your thirst on the road, get some ice cubes to bring with you, and go with so-and-so." By the way, carry those hand-cranked fans away again. "Li Shimin really didn't want to be an outsider, this posture is to move.

With mixed feelings of joy and sorrow, after finally sending off Li Shimin and their huge team, Lin Sen looked at the Li Zhi brothers and sisters and couldn't help muttering.

For goodness, no wonder there will be such a performance later, it turns out that the root is here, "hypocrisy", it is carried in the name, I'm afraid it is not easy to change.

But the little son still looks so cute, or let's do some business together, or what about the little son brand? Why do you think this name is so appropriate......?
