Song Yi's whole family is helping in the restaurant, eating and living in the restaurant, Song Yi doesn't know what Zhen Qian is going to do, just call his two sons if he has something, and call the two daughters-in-law to do something, but since the owner said it, he didn't want to ask too much, so he followed Zhen Qian to a side room next to him.

"Is there any ice here?"

Song Yi immediately shook his head, what does this thing do in a small family, unlike a large family that has an ice cellar.

Zhen Qian then said: "Then take two clean wooden basins and copper basins, and then those sugar, milk and fresh fruits?" ”

Song Yi was even more depressed, he just said that he wanted to buy some ice cubes and put them in the restaurant, was Zhen Qian's posture to prepare for cooking?

On the side, the daughter-in-law of Song Yi's two sons was even more depressed, the Tang Dynasty was open, and the defense of men and women was not strict, and it was not uncommon for women to wander around the streets with curtain fences, or directly wear men's clothes on the street, but after all, men and women are still different, and I don't know what Zhen Qian is going to do?

"I'll do it now, you watch me do it", Zhen Qian said and took out the saltpeter and poured it into a wooden bucket filled with water, there is no difficulty in making saltpeter ice at all, it is just a novel idea.

Saltpeter put into the water, stirred with a wooden stick and slowly dispersed and diluted, the water gradually became turbid, and then turned gray-white, and then the water began to churn, as if quicklime entered the water, and the basin surface came out of the steaming white gas, Song Yi's family was also attracted by this vision, staring intently at the basin, and soon the water stopped boiling, began to solidify, and the water surface formed a unique ripple of ice.

A few people gathered around Zhen Qian, and they didn't know what Zhen Qian was going to do, so let yourself watch it! But the more I looked at it, the more surprised I became, and then I was shocked, and finally when I saw a large piece of cold ice in the copper basin, I couldn't speak!

"This ...... This is a miracle! ”

Song Yi saw the ice cubes appearing in the copper basin, and as soon as his legs were weak, he wanted to kneel down, and he was about to kowtow to the copper basin.

Zhen Qian, who knew that there would be such a situation, grabbed Song Yi and said: "This is not a miracle, nor is it an immortal art, but this is indeed a secret that is not passed on, I will hand it over to your whole family now, you can't teach it to outsiders in the future, otherwise there will be retribution!" ”

It is still necessary to scare it, if it is spread out, his plan to make a fortune will be ruined. But Song Yi's family didn't have such an idea, they were already frightened by the phenomenon in front of them, and thought that Zhen Qian was some kind of mysterious spell, or maybe it was a secret that was not passed on, so they hurriedly nodded and agreed.

Wang Qun, who had known what was going on, kept silent, even if they already knew what was going on, they were also shocked in their hearts.

Zhen Qian also did not expect that the Tang Dynasty already had a primitive juicer, a lever wooden structure pressure bar device fixed on a bench, put the fruit into the groove, the juice outlet and the groove are connected, and the fruit in the groove is squeezed out of the juice by using the lever principle, which is very similar to the common dough pressing device in Shaanxi in later generations.

I first made a basin of pure ice cubes, and then made a basin of fruit juice water with milk, sugar and fruit juice to make a basin of juice drink ice cubes, and scraped a few bowls of ice cream from the ice cubes with a planer and handed them to the people around to taste.

"How about you try it?"

Song Yi's family held the frost cold drink that appeared out of thin air in their hands, and they didn't know what to say for a long time, this is too unbelievable, if they hadn't seen it with their own eyes, they wouldn't have believed that there would be water freezing in summer anyway, but all this really happened in front of their eyes.

Song Yi couldn't taste what the frost cold drink was like, and the whole person was dizzy, and even felt that there was a Sanskrit sound ringing in his ears.

Song Yi's two sons, Song Yu and Song Jiang, held a copper basin of ice cubes and smirked, "Summer ice making is amazing, and now the business in the restaurant is going to be hot!" ”

Zhen Qian stretched out his hand and slapped Song Yi on the shoulder, pulling the distracted Song Yi back from the dream and said: "The method of making ice from saltpeter has been handed over to you, in addition to adding milk, sugar and juice to the ice, you can also add some cooked red beans, mung beans and nuts, etc., to make different flavors of frost for sale, you can also use bamboo tubes to take out, and then let your two daughters-in-law go to Zhen's mansion to learn the craft of making cakes with Xiaozhu and Xiaomei, and in the future, Zuixianlou will not only serve dishes, but also supply all kinds of snacks and frosts, Do you think this summer business can catch fire? ”

"Yes...... Absolutely! ”

Song Yi replied without thinking: "As long as there is a steady stream of ice, the business of the restaurant will prosper, plus Zhen Lang's frost and cakes, it is difficult for the restaurant to become famous?" ”

"You can rest assured that you can use saltpeter to make ice, and after melting, put the water in the wooden basin in the sun to expose it to the sun, you can regain the nitrate frost and use it repeatedly, and I brought you a lot of saltpeter, enough for you to make ice in summer?"

"Since Zhen Lang has taken it into account, there is no problem!"

As Song Yi, who has more than ten years of experience as a shopkeeper, Zhen Qian doesn't need to ask anything at all, if a leader stretches his hand too long, it will discourage the enthusiasm and autonomy of employees, just simply give instructions on precautions and some sales strategies, and other things will naturally not interfere with Song Yi.

Song Yi kept it in mind and asked a few more questions: "I'm afraid the price of this frost is not low!" And is it appropriate to put it in the restaurant for sale, after all, there are not many people who go to the restaurant to eat during this time, can you find some people to promote it? ”

"The price of frost is not a problem, you can buy one get one free at the beginning, you can control the cost price, I won't interfere, as for the sales problem, ......", Zhen Qian found that the location of the Drunken Immortal Building was still a little remote, and there was no way to do it, so he thought for a moment and was a little unsure: "Can we push the frost cold drink to the side of the road to sell, just like the merchants on the side of the road?" ”

Wang Qun on the side said: "This method is good, isn't the Hu cake shop next to the restaurant often carrying the burden to sell everywhere in the city?" ”

In later generations, there were chengguan, I don't know if there were similar regulations in the Tang Dynasty, in case there were any restrictions, Zhen Qian asked cautiously: "Don't you care about the officials on the street?" ”

"This?" Song Yi frowned and said: "If we push the frost to the street to sell, not only will it be a servant, but it will also attract a lot of idlers, I think it is better to sell it in the market, where as long as you pay a little tax, you can set up a stall openly, and we are just starting the brand of Zuixianlou, not a long-term operation, or a restaurant business, so there will be much less trouble?" ”

Zhen Qian doesn't want to attract attention now, but he can't keep a low profile, the tepid reputation of Drunken Immortal Tower makes people anxious, so he can only go sideways.

"So be it! It's a big deal to stuff a few more money into those servants, and you can even make some more ice water for free for some porters and merchants passing by, and then buy two older maidservants to help ...... in the store. ”

"Good! I'll go to the slave market and have a look," Wang Qun turned and walked aisle.

Song Yi on the side also said to the two daughters-in-law: "You burn some red beans and mung beans, get some fruits and nuts, make more frosted cold drinks and give them to the surrounding neighbors to taste, and by the way, go to the Hu Cake Shop next to you, and borrow their cart for a few days ......."

Then he said to his two sons: "You two will do the ice-making steps that Zhen Lang taught you a few more times, prepare more wooden barrels and copper basins, and this place will be used exclusively for ice-making in the future, and no one else will be allowed to enter!" ”

Zhen Qian and Wang Qun did not continue to disturb the arrangements of Song Yi's family, after withdrawing from the room, Wang Qun went to the slave market, and Ju Niang, who jumped off beside him, was not afraid that her teeth would be frozen by the ice, and she actually stood in the scorching sun with a large bowl of frost and sweated and struggled, swallowing it in one gulp, grinning with cold teeth in her mouth, and seeing Zhen Qian come out, she hid a bowl of frost behind her in a panic, and threw Zhen Qian a very cute smile.

"Be careful that your teeth are frozen, you go and ask Wang Sheng, the last time he had a toothache, he hit his head against the wall and knocked himself unconscious, it's useless, don't you want to give it a try?"

Ju Niang glared at Zhen Qian viciously as if she was frightened, "Didn't you say last time that you would have a toothache if you ate too much sugar?" Now I say that eating ice will give you a toothache, so I won't believe your nonsense! ”

"If you don't believe it, forget it!"

Zhen Qian didn't think that Ju Niang would definitely believe in herself, and saw Song Yi walk out of the room and said, "Let's have a meal here at noon before leaving, you go and prepare!" ”

It was almost noon, the restaurant was scorching under the scorching sun, it felt like walking into a steamer, Zhen Qian and the others found a relatively cool corner to sit down, Song Yi brought a few pots of prepared ice cubes to the restaurant and put them in a ventilated place in the restaurant.

Soon a few bowls of freshly baked frost were served, and Wang Peng asked for a pot of soju, put it on the ice cubes and chilled it, waiting for Wang Qun to come back and drink it together.

Zhen Qian asked for a bowl of wine, put in a few pieces of ice, a glow-in-the-dark glass of grape wine, a missing glow-in-the-dark cup, and shook the big bowl a few times with the "bell", and the cold wine entered his throat along the taste buds, and he couldn't help but praise "Good wine!" ”

Song Yi didn't know when he appeared at the table with a middle-aged man in his arms, and several people on the table stood up in unison, "Wake up!" ”

"Wake up...... I just woke up! ”

Song Yi helped the middle-aged man to sit down, it was Yan Ming who was rescued in the mountains yesterday, "I just entered Sergeant Yan's room and found that Sergeant Yan woke up, so I told him that Zhen Lang was in the restaurant, and I had to thank Zhen Lang in person!" ”

"Sergeant Yan!"

Zhen Qian felt that this title was a bit strange, and he also called Song Yi together: "Sergeant Yan ......."

Yan Ming raised his weak arm and said: "Don't call me Sergeant Yan, since I have quit the army, I used to be just a team leader, but now I am an ordinary person who goes home to farm, you can call me Brother Yan and Yan Erlang!" ”
