"Well, my son is well-read, and he is not allowed to drink raw water in the future."

The mother of the Li family is really better than Li De, and all the maids of the middle family responded.

"De'er, it's convenient and practical for you to make these things, but it also costs money to make these things." Zheng Shuxuan said worriedly.

If you don't know how expensive firewood and rice are, Zheng Shuxuan, the mother of the Li family, has always advocated thrift and thrift, not that you can spend it indiscriminately if you make money, Li De spends a lot of money on these things, she knows it.

The things that are made are just convenient and easy to use, but they are all possible, and even if they don't make these things, they have never delayed the use of water in the past.

Now it looks like a lot of investment, but it may not be able to be used to make money, you must know that there is a saying called promotion, and there will definitely be discerning people in the subtle way.

"Mother's meaning, the son understands, apply what he has learned to make something, and don't forget the things taught by the master, in fact, the cost is not large, and the current income of the hot pot restaurant can be fully coped." Li Dedao.

Spending money is always the most concerned thing for the housemother, no matter who is in the house, it is necessary to settle an account, Zheng Shuxuan is not afraid that he will spend money but must have control, otherwise the accounts are not clear, and how will the Li family live in the long run.

"It's good that De'er knows it."

Zheng Shuxuan thinks about how much the hot pot restaurant earns, she really doesn't know, but the business of the store has always been very good, so she shouldn't worry.

"Mother, these things cost hundreds of times, don't worry if the eldest brother is really rich." Li Yang saw her mother pondering and immediately explained.

Pig teammates mend the knife, that's it, but which pot doesn't open which pot.

"De'er, these are just some bamboos how to spend so much money, aren't they being deceived." Zheng Shuxuan asked.

"No, how can people be deceived, that's what is done with research and development, and a lot of tests will be done before the device is manufactured, such as the sealing connection between bamboos, the opening of bamboo tubes, etc., all of which cost more money." Li De explained.

Zheng Shuxuan realized that the simple bamboo splicing she saw in front of her was actually a surface, and she had done a lot of work before, so it didn't cost much.

Zheng Shuxuan didn't know much about these things, and she was naturally happy when she saw Li De.

"Ying'er, you have to learn from your brother, it's good to apply what you have learned, what grades have you achieved after reading so many books?" Zheng Shuxuan immediately asked.

"Well, the opinion of Mr. Gefu of the son's poetry in the country is still in the past." The more Li Ying spoke, the quieter his voice became.

"Don't be embarrassed here, go back with your mother, and test your knowledge today to see if you are usually lazy."

"Mother, I don't think it's necessary."

Li Ying really didn't want to be taught a lesson, but it backfired, so he knew that he wouldn't intervene.

After Zheng Shuxuan left with Li Ying, many people were looking at the bamboo tube to guide the water, and they felt novel.

"Wen Hui, you're alright." Qiao Yue said enviously.

Qiaoyue is now mainly serving Zheng Shuxuan's maid, and she uses a wooden bucket to fetch water every day, not to mention that every time she beats half a bucket of water and pours it into the middle of the wooden basin.

Wen Hui didn't know how to answer, who knew that the eldest prince would be able to make such a thing.

"Eldest son, why don't you give up the water room to Qiaoyue, it's the same if I get up early every day to fetch water." Wen Hui said softly.

"Don't worry, there will be a new water house in the backyard of the main house." Li Dedao.

"Did Qiaoyue hear it, what the eldest prince said."

"Yes, I heard you." Qiao Yue said happily.

Qiaoyue was happy, but the Lu brothers on the side were not very happy, the bamboo tube pipe was quite successful, but the underground conduit was bamboo, in order to close the connection, they used fish bladder glue.

This kind of glue is a bit troublesome to refine, not to mention the collection of raw materials, you need to master the heat when boiling, and a lot of swim bladders and time are wasted in the preliminary test.

Although the Lu brothers are craftsmen with rich experience, they still made it after repeated attempts under Li De's extremely strict requirements, the quantity is not too much, and the use is also very particular, but it is not just smeared.

"Eldest son, what about the fish left in the kitchen, there are too many quantities and it is estimated that they will not be able to eat it in a few days." Li Fu walked up to Li De's side at this time and asked.

Li De pondered for a moment and said: "Ask the cook to clean all the fish, puree, put it in a big bowl of wine to marinate, and wait for me to come over and make plans later." ”

Li Fu left with the task, he knew about the fish gelatin, although he didn't know the specific production process, but so many fish had to be pondered without fish bladders.

As soon as Chen Xuanhua heard the food on the side, he leaned over and said curiously: "Li Gongzi, is there something delicious again, what is it?" ”

Li De looked at this foodie, and he was also speechless, since he had eaten stir-fried vegetables, he seemed to have no interest in the original boiled and steamed food.

"Of course it's delicious, why should I tell you." Li Dedao.

"Hehe, Gongzi Li, Brother Li, just tell me." Chen Xuanhua's attitude immediately changed rapidly, where was the arrogant attitude he once had.

"Oh, call me Brother Li when you want to please, and call me Gongzi Li when you don't need me, so I won't be fooled by you."

"You, hmph, this girl knows who you are, one thing in front of you and one thing behind your back, why don't you talk to my sister-in-law like this." Chen Xuanhua stubbornly refuted.

"Just think, when you start eating, you'll know what to eat, and it's useful to be anxious." Li Decai was not used to her, and chose to ignore her directly.

"Brother Lu family, then you will be responsible for making the water supply and water supply system, and all the places in the house where there are wells must be connected." Li De commanded.

"Yes." The Lu brothers know the difficulty of the project, and they will still do what they are told.

The Li Mansion was very keen on new things, and after Li De finished telling the matter, the onlookers were still there, and Li De didn't let them leave like that.

There is still a great attraction to new things.

After dealing with the matter, when he arrived in the back kitchen, he saw that a large pot of fish had been marinated according to his method.

"The eldest son." The two cooks greeted each other.

"Okay, prepare egg flour and boil water in a cauldron."

Li De did what he ordered, and the two cooks immediately did so.

Mix the fish in the large bowl with eggs and flour, and instruct the cook to pinch the fish balls, and let the fish balls fall into the pot while kneading, and the water temperature is appropriate.

Li De took a big spoon and stirred it gently in the pot, and the magic was that the fish balls fell into the pot and formed quickly, and the fragrance of the fish wafted out in the pot.

The soup base for boiling fish balls is a good thing, and it can be used as a broth, so it occurred to me that it can be used for a hot pot restaurant, so I can try the taste of fish ball hot pot at home today.
