"Childe, now our crispy roast duck is becoming more and more famous, and the turnover of buying ducks from other places these days has reached three hundred taels of silver, and today there is a guest official who came from Yingtianfu!"

Yuelaiju's business is so hot that it is beyond the imagination of Shopkeeper Wu, and he has always been smiling from ear to ear, especially when taking inventory. Today, the daily turnover of restaurants and delicatessens exceeds 600 taels of silver, and nearly 20,000 taels are paid in a month, so ...... In the past, Shopkeeper Wu didn't dare to think about it.

Han Feike does not have the idea of a small peasant who is rich and peaceful, and his vision has gone beyond Gaochun County. God threw him a super plug-in, if he didn't make a huge wave, how could he be worthy of God's love? He looked at Shopkeeper Wu with an ecstatic look, smiled faintly, and said: "Uncle Wu, although crispy roast duck and cooked food are delicious, there are times when you are tired of eating, and after a long time, the turnover will inevitably decline!" ”

"Ah......" Shopkeeper Wu was taken aback, and then understood the meaning of Han Fei's words, and couldn't help but hurriedly say: "Childe, then what countermeasures do we have?" ”

"Gaochun County is so big, the market is close to saturation, if you want to maintain the sales momentum of crispy roast duck, you have to open up new markets, and the neighboring county government is the first target!"

"Childe, the nearest county town to Gaochun County is also more than 100 miles away, and other places are even farther, and it takes a lot of time on the road.

"Uncle Wu, this is indeed a big problem, I will think about it and think of a way to solve it! Actually, the best way is to open a local store, but unfortunately...... Alas! ”

"Childe, what is the pity?"

"Uncle Wu, there are no competent people! Yuelaiju is developing too fast, too late to cultivate independent talents, there is no reliable person in charge, how to talk about opening a store? ”

The Liang family died so that only one Mrs. Liang who didn't know how to operate was left, and the Han family was only Han Fei alone, this was a cruel fact, and the shopkeeper Wu suddenly fell silent.

At present, the emergency strategy is to find a way to extend the shelf life of crispy roast duck, otherwise, even if more foreign merchants come to buy it and bring it back to the local area to change the taste, it will also affect the reputation of the roast duck. But this point is a big problem in this era, there are no refrigerators, freezers, and incubators at all in this era, even if Han Fei has N strategies in his head, he cannot implement them due to objective conditions.

It's already May, the weather is getting hotter and hotter, and the problem of shelf life of roast duck is even more severe.

Using ice cubes to make a refrigerator-like thing is a more effective method. In this era, there was already a technology for saltpeter to make ice, but the main source of saltpeter was saltpeter ore, and the quantity was small, and the cost was very large.

There are two problems to be solved, one is the mass production of saltpeter, and the other is how to adapt it to long-distance transportation. The former problem is relatively easy to solve, as soon as the super system in Han Fei's brain searched, a large amount of information appeared, and the cost was low, such as the heating crystallization method by mixing soil nitrate and plant ash into water. The soil nitrate is widely distributed, and the soil walls of the old houses are generally contained, and the soil content in the toilet is abundant.

The latter problem is more difficult, and in this kind of weather, the ice melts very quickly and does not make much difference.

Suddenly, a scene jumps out of the super system, and in some old movies in another time and space, there are often vendors pushing bicycles and selling popsicles. The wooden box behind their car is equivalent to a simple refrigerator, yes, with thick cotton wool can achieve the effect of heat preservation.

"Uncle Wu, I have thought of a way to extend the quality of roast duck!" Han Fei happily called to the shopkeeper Wu.

"Childe, how can I do it?"

Jia Ming also said on the side: "Yes, big brother, how can you do it?" ”

Han Fei glanced at Shopkeeper Wu and Jia Ming, and said with a smile: "Let's make a wooden box, and make a mezzanine in it, put roast duck in the middle, and put ice cubes in the mezzanine, so that the quality can be guaranteed, and it is the same reason that winter food is not easy to spoil!" ”

"Big brother, this method is very wonderful, but the ice cubes are easy to melt!"

Han Fei smiled at Jia Ming: "Let's wrap the outside of the mezzanine with thick cotton wool, and we can keep the ice cubes from melting for a day or two!" ”

Shopkeeper Wu thought for a while and said: "Childe's method is more suitable for large customers, but it is difficult for small customers to do it, at this time, the price of ice cubes is high, which will inevitably increase the cost of roast duck!" ”

"Haha, it's not complicated to make ice, it's just a matter of adding some saltpeter to the water!" Han Fei said happily: "Uncle Wu, I have already thought of a way to make saltpeter, which can produce a large amount of saltpeter!" In addition, after the ice cubes made of saltpeter are melted, they are recycled and heated to extract saltpeter! ”

Jia Ming took over the conversation excitedly: "Big brother, then let's hurry up and make saltpeter, when it's hot, we can still eat chilled fruits!" ”

"Brother, you have found a money-making business for us again, selling cold drinks in the summer must be very profitable, haha......"

"Big brother, you know how to make fun of me!"

"Brother, I mean really, in the summer, you can sell some cold drinks or something in the deli! In this way, you will be in charge of the workshop that makes saltpeter, and then I will go and talk to Huang Tuantou, and ask his beggars to help us collect raw materials! ”

Han Fei turned his head and said to the shopkeeper Wu: "Uncle Wu is partial to the production of wooden boxes!" In fact, the best way is to go directly to the other place to open a store, but it's a pity that ......"

"Childe, there is no way to do this, I can only talk about it later!" Shopkeeper Wu also sighed.

"To open up the market in other places, it is imperative, their own training of the person in charge of a few years is not good, I think there are two ways at present, one is to hire an experienced shopkeeper, and there is a partnership with others!"

"This is also a way in the middle of nowhere, I don't know which one the son prefers?"

"Let's do the two methods at the same time, Uncle Wu, you pay attention and see if there are any suitable candidates, I will go to Yipinxuan and Sihaiju tomorrow to see if they have any intention of cooperating!"

Compared with Yipinxuan and Sihaiju, Han Fei is naturally closer to Yipinxuan, after all, the He family is also a villager.

The next day, Han Fei asked Jia Ming to stay in Liang Mansion to prepare for the manufacture of saltpeter, and rushed to Yipinxuan alone.

"Brother Han, what kind of wind blew you here? Haha......"

Yipinxuan cooperated with Yuelaiju and got huge benefits, and He Chengfei, the second young master of the He family, was quite enthusiastic about Han Feizi.

"Brother He, you're polite, the younger brother has nothing to do but go to the Three Treasures Palace!"

"Brother Han can send a guy to inform him if he has something, why bother to run in person?"

"This matter is more important, I have come to discuss with Brother He!" Han Fei took a sip of tea, and then said: "Brother He also knows that now the reputation of crispy roast duck has spread widely, and the younger brother thinks about taking this opportunity to do the roast duck business to other places, but the strength of the younger brother's family is limited, and he wants to join forces with the He family, I don't know what Brother He wants?" ”

He Chengfei frowned slightly when he heard this, the He family's business had already been done all over the place, and the willingness to partner with Han Fei was not great. But judging from the situation in Gaochun County, the market potential of crispy roast duck is huge, and he is a little tempted.

"Brother Han, the matter of opening a store in partnership is relatively big, and the younger brother can't be the master alone, and he has to ask for the consent of his father and brother, can you give it a few days?"

Han Fei could see that He Chengfei was hesitant, so he said: "Brother He's difficulties, the younger brother can understand, to tell the truth, we are fellow villagers, and the first partner that the younger brother thinks of is the He family!" In this way, the younger brother will wait for three days, and if the He family is not willing, the younger brother will negotiate with the Zhang family! ”
