The business of the Immortal Building is extremely hot.

Every day, there are many customers, and most of them are repeat customers, some of whom come to taste high-quality sake, and some who taste stir-fried food, from the lobby below to the private rooms upstairs, are full.

Yang Yun did not focus on the high-end market, he knew that it was difficult for the most common people to pursue the high-end, simply known for its high quality and low price, the only exception is the high wine, this wine is five times more expensive than the wine on the market, but the customers are still flocking, a few days later and even in the afternoon, there are guests to drink, order one or two such as braised pork head, braised duck intestines and other side dishes, and be content.

However, by the time of normal business hours in the evening, the wine usually runs out...... The speed of Yang Yun's brewing is obviously not keeping up with the sales speed.

"Host, the wine is basically sold out in the afternoon these days, and there are many fewer customers in the evening, after all, many diners come for our wine......"

When Song Qi reported the accounts to Yang Yun, he was also happy and worried.

The money is earned, there are four or five yuan of money every day, and the turnover could have been made higher, but Yang Yun just does not increase the supply of wine, and only sends two jars of wine to the wine store every day, and customers can only enjoy one pot per table.

If you have money, you don't make money, which makes Song Qi incomprehensible.

Yang Yun said: "The production of wine here is insufficient, so I can sell as much as I want...... However, since the sales of this wine are good, I will increase the production appropriately in the future, but the principle set before cannot be changed, you must drink alcohol in the wine store, if a customer insists on taking the wine away, he will not be allowed to enter the store in the future, and whoever makes trouble will be blown away. ”

"Yes, yes."

Song Qi obeyed Yang Yun's orders, "The owner, the matter of hiring helpers ......"

Yang Yun nodded: "Hire four more people to come back, add two people to pick vegetables, wash vegetables and cut vegetables in the back kitchen, one of the two running halls is responsible for the lobby, and the other is responsible for the private room upstairs." ”

"As for the lack of manpower in the kitchen and the problem of untimely dishes, doesn't Xiaohua also cook? Hire an extra mother-in-law to help, and make two stoves to specialize in steamed dishes...... I will teach her to make a series of tamales, any pork intestines, pork belly, and pork ribs can be steamed with rice noodles, and the other is roasted white, sweet roasted white and salty roasted white are all very good dishes......"

The names of these dishes that Yang Yun said were unheard of by Song Qi.

As the so-called skills are not pressing, hearing that there are new dishes to learn, although it is only his own daughter to learn, Song Qi is still in good spirits. The advantage of steaming vegetables is that the steamer can be served hot at any time, which can buy time for the stir-fry to come out of the pot.

The owner always has so many tricks, which is eye-opening, and Song Qi is more confident in running a wine store in the future.

……

……

Yang Yun did business for the first time and made money, not only the Song family was happy, but Yang Yun was also very relieved, and the sisters An Lun, Yarou and Yaqing were also very happy.

However, the three sisters are very tired these days, because Yang Yun makes them make wine every day, as if they have become poor child laborers.

When Yang Yun came back in the evening, the three sisters had already packed the two jars of wine that they were going to sell in the future, An Lun grabbed Yang Yun's sleeve and said bitterly: "Master, it's too hot to guard the stove in summer, even if you fan, you always sweat." ”

Yang Yun said: "You sisters don't need to do this in the future, I have rented the yard next door and invited craftsmen to renovate it, and now it is almost completed, so I will wait for someone to come back to work...... From now on you will be responsible for being overseers. ”

Yarou asked, "What is an overseer?" ”

An Lun explained for Yang Yun: "Sister Rou, the overseer is someone else's work, we just watch from the sidelines, if we don't do it well, we have to point it out and let them improve." ”

Yarou couldn't help but breathe a sigh of relief when she heard this, she was distressed by her sister Yaqing's hard work these days, but she felt that it didn't matter if she was busy.

Yang Yun felt pity and said: "It's been really hard for you during this time, I'll make some good things out when I go back, it's just the summer heat, you can use it to quench your thirst...... Tomorrow I will start to work as a supervisor with peace of mind, and I can direct the workers to do things. ”

……

……

Yang Yun completely renovated the courtyard next door.

For secrecy, three stoves are housed in the same room, and an elaborate chimney exhausts the smoke from the combustion. The inlet and outlet of the three steaming utensils are opened in separate rooms, and the three pipes of the final wine are concentrated in another room.

As a result, workers only have to do mechanical and repetitive things in different rooms, and it is difficult to get a full picture of the entire brewing process.

The next day, the winery was officially put into operation, which can basically ensure that eight to ten jars of wine can be brewed in one day.

Yang Yun recruited four aunts from his neighbors to work, one was responsible for lighting the fire, the other was responsible for pouring the brewed liquor bought from the market into the big wooden retort, one was responsible for draining the residue after the distillation of the liquor, and the last one was guarding the outlet to collect the distilled liquor.

The three girls wandered around the rooms, coordinating the entire brewing process, and they only had to move their mouths, and they were finally relieved from the heavy labor.

Yang Yun also had to take care of the errand of the gunpowder workshop, and the next morning he pretended to finish the method, carefully collected the ashes of the rune paper, put it into a small cloth bag, and put it in when the final gunpowder was synthesized, and today's errand was completed.

Yang Yun looked up and saw that it was still early, so he officially started the experiment of making ice with saltpeter.

As far as he knows, the ancients wanted to make ice cubes, all of which were made of saltpeter, but Datang had not yet mastered this technology, Yang Yun saw the hard work of the three little Loli in the family, so he decided to make some ice cubes to relieve their heat, and this is also a useful attempt, this kind of ice drink may make their wine shop business more prosperous.

"As long as there is no food in this era, I can make it and send it to the Immortal Building, and I can drink a glass of ice water in the hot summer, how pleasant is that? Don't attract a lot of customers when the time comes? ”

There is no technical difficulty in making ice with saltpeter, only two containers of size need to be set together, each holding water, and the outer container is poured with saltpeter, which will absorb a lot of heat when it encounters water, instantly reducing the surrounding temperature and freezing the water in the internal container, as simple as that.

Moreover, saltpeter ice making is economical, and saltpeter can be obtained again by evaporation and crystallization, which can be recycled.

"You can't find saltpeter anywhere else, but I have a lot of gunpowder workshops, and if I don't make good use of it, I'm sorry for my mind hundreds of years ahead of this era."

Yang Yun was busy with the business of the Immortal Building in his spare time a few days ago, but now that everything has stabilized, he has plenty of time to make saltpeter ice.

Jiedu made Wang Yu attach unusual importance to the manufacture of gunpowder, which made the state and county governments of Jiannan Province very active, desperately collecting saltpeter and sending it, many of which were of high purity and could be used directly.

As for the utensils that hold water, they are everywhere, and Yang Yun only needs to do an experiment with his own hands.

Put a large wooden basin on the stone slab, and put a small wooden basin inside, each put in the well water, Yang Yun put the saltpeter directly into the large wooden basin, and then covered the basin with a lid, and soon he felt a bone-chilling cold, and couldn't help shivering.

After about a stick of incense, Yang Yun felt that the chemical reaction was basically completed, and when he opened the wooden lid, the water in the small wooden basin had frozen, although it was not a complete ice cube, most of them were crushed ice, and Yang Yun was very satisfied.

With a glass of ice water, Yang Yun suddenly felt refreshed, and the heat was gone.

"The technology can be appropriately improved, the outer insulation layer should be strengthened, and the small basin inside cannot be used with a wooden basin, the wall of the wooden basin is too thick, not suitable for conducting temperature, but for the time being, it can only be settled."

……

……

Yang Yun spent half a day, and by the afternoon, there was finally better ice available.

Drinking ice water and watching the craftsmen busy, Yang Yun felt very comfortable.

I was about to clean up, take some saltpeter home, and show the three little Lori how to make ice, when someone came to report that the king was here.

"It's good that the master is here, I'm looking for you here." Wang Ji was very happy, didn't pay attention to the teacup on the table, sat down and said with a smile.

Yang Yun's expression was indifferent: "What's the matter?" It doesn't hurt to be straight. ”

Wang Ji said: "That's the case, there is news from the front line, the festival commander is preparing for the class, and it is estimated that he will be able to return to Chengdu in half a month." ”

Yang Yun bowed: "What do you mean...... Don't make spells? ”

"Where is this? If you want to build, you have to make it."

Wang Ji said nervously, "I heard that the next plan of the festival marshal is to ask the imperial court to lead troops to recapture Huiye City, geographically speaking, Huiye City is much more important than Luoyan Prefecture and Dangma and other states, just like the sword that Tubo inserted into my Tang Dynasty, if you don't pull out this sword, the people of Jiannan will not be able to sleep well." ”

"Hmm."

Yang Yun nodded.

He knew that Huiye was the Kangding of later generations, and a few miles to the west was Zheduo Mountain, which was four or five thousand meters above sea level, and there was no one to inhabit, as long as Huiye City was taken, Tubo could only retreat from the Jinchuan River basin to the Nuoyi River, that is, the Yalong River basin in later generations, and every attack on the Tang Dynasty would be several times more difficult.

Wang Ji sighed: "Huiye City is not so easy to take, Tubo has been operating in Huiye for many years, and has built perfect fortifications, even if the fire charm is strong, it is not easy to attack it, the idea of the commander is ...... See if there's room for improvement? ”

Yang Yun frowned: "Improvement? ”

Wang Ji said with a smile: "As far as I know, this fire talisman is developed by the master master, in addition to the raw materials, it also needs the fire talisman drawn by the little real person to work, if the master improves it, will the power become stronger?" ”

Yang Yunxin said: "The human heart is not enough to swallow the elephant, and the power of making black powder is not enough, do you want me to study yellow powder?" Or just let me give you the atomic bomb. ”

Yang Yundao: "I said before that the family teacher travels all over the world and has no fixed residence, so I can't ask him for advice. ”

Wang Ji said with a smile: "Master, don't fool people...... I just heard that the Venerable Master is about to arrive in Chengdu. ”

This news made Yang Yun very surprised, and he frowned and asked, "Where did this news come from?" ”

Wang Ji said: "This time the Qingyang Palace held a festival, and all the Taoist temples in Jiannan Province will send disciples to attend...... It is not far from Daojiang County to Chengdu, and it can be reached in a few days. ”

Yang Yun muttered in his heart: "A person who obviously doesn't exist, but he is said vividly, and even his whereabouts are known, won't he be chasing after the wind?" ”

Yang Yun shook his head: "No, how can Shizun be in Qingcheng Mountain?" ”

"Could it be that you didn't cultivate in Qingcheng Mountain before? That's strange, I heard that Qingyang Palace has sent the invitation to Qingcheng Mountain Wuzun Zhenren, but you said......"

Wang Ji didn't understand it very much, and finally found the person, but Yang Yun didn't admit it, which was really strange.

Yang Yun thought to himself: "It can't be a ghost trick played by Qingyang Palace, right?" Finding someone to pretend to be my master, and then defeating him openly, will damage my reputation and demonstrate the prestige of Qingyang Palace as the orthodox leader of the Jiannan Daomen...... But the question is, what if I don't admit it? ”

Yang Yun said: "In short, I haven't seen it with my own eyes, and I can't be sure if it's a master." ”

Yang Yun did not directly deny it, many things should be observed calmly, he knew very well in his heart that the current royal family does not represent Qingyang Palace, but the Yamen of the Jiedu Envoy.

Jiannan Jiedu made Wang Yu sick and rushed to the doctor, eager to find Wuzun Zhenren.

Wang Ji smiled: "Also, I haven't seen anyone yet, who knows if it's an impostor?" However, since the master is here, he will definitely distinguish that if someone impersonates, the Taoist and the marshals of Qingyang Palace will not let him go, so that he can't eat and walk around. Hey? What is it? ”

In the end, Wang Ji finally found that the teacup in front of Yang Yun was different, the water in it was floating with crystals, and he subconsciously stretched out his hand, but before enough, a chill had already hit.
