"Well, my son is knowledgeable and knowledgeable, and he will not be allowed to drink raw water in the future."

The mistress of the Li family's family's words were really better than Li De, and all the maids of Ding from the middle family agreed.

"De'er, it's convenient and practical for you to make these things, but you can't afford to make these things." Zheng Shuxuan said worriedly.

If you don’t be a family, you don’t know how expensive it is. The mistress of the Li family, Zheng Shuxuan, always advocates thrift and frugality. It’s not that you can spend money by making money. Li De’s expenses for these things are quite expensive, and she knows that.

The things made are just easy to use, but they are all possible. Even if you don’t make these things, you have never delayed the use of water.

It seems that it is a lot of investment now, but it may not be used to make money. You should know that there is a saying called promotion. There will definitely be people with discerning eyes in the subtle way.

"My mother means that my son understands that he will apply what he has learned to do to make some things and never forget what his master teaches. In fact, it is not much. At present, the income from the hot pot restaurant can be fully dealt with." Li Dedao.

Spending money is always the most concerned thing for the mistress. No matter who she is in, she has to make a calculation. Zheng Shuxuan is not afraid of him spending money but has to control it. Otherwise, if the accounts are not clear, how can the Li family live in the long run?

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

Zheng Shuxuan thinks about how much the hot pot restaurant earns, but the store business has always been very good, so there should be no need to worry.

"Mother, these things cost hundreds of coins. Brother really has money, don't worry." Li Yan explained immediately when he saw his mother pondering.

The pig teammates finished the fight, that's it, but they just need to pick up the pot of the pot.

"De'er, these are just some bamboos that cost so much money? Could it be that someone has cheated them?" Zheng Shuxuan asked.

"No, how could people cheat? This is what is happening with R&D. Many tests will be done before the device is manufactured, such as sealing connection between bamboos, opening up bamboo tubes and other tests, which will cost more money." Li De explained.

Only then did Zheng Shuxuan realize that the simple bamboo splicing I saw in front of me were actually superficial, and I had done a lot of work before, so it was really not a lot of money.

Zheng Shuxuan didn't understand these things very well, and she was naturally happy when she saw Li De.

"Your Ma, you have to learn from your brother. It would be great to put this into practice. What achievements have you learned after reading so many books?" Zheng Shuxuan asked immediately.

"Well, my son's poems and songs in the Imperial College are just as good as he can." Li Ying's voice became smaller and smaller.

"Don't embarrass you here. Go back with your mother. Today I will test your knowledge to see if you are lazy in normal times."

"Mom, I don't think there is any need for this."

Li Jing really doesn't want to be taught a lesson, but things went against my wishes. If I had known this, I wouldn't have interrupted.

After Zheng Shuxuan took Li Yu away, many people were watching the bamboo tube water guide, feeling very novel.

"Wenhui, you're fine." Qiaoyue said enviously.

Qiaoyue is now mainly serving Zheng Shuxuan's maid. She uses wooden barrels to fetch water every day. Not to mention being bulky, she always makes half a bucket of water and pours it into the middle of the wooden basin. Now, it is very good to use water in a water room, and it doesn't have to work so hard. She is envious of the blue.

Wenhui didn't know how to answer, but who knew that the eldest son could make such a thing?

"Young Master, why don't you give the water room to Qiaoyue? It's the same if I get up early every day to get some water." Wenhui 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? The eldest son said it."

"Yeah, I heard it." Qiaoyue said happily.

Qiaoyue was happy, but the Lu brothers beside her were not very happy. The bamboo tube pipe was quite successful, but the underground conduit was made of bamboo. In order to close the connection, they used fish bladder glue.

This 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 fish bladder and time is wasted during the preliminary experiment.

Although the Lu brothers are craftsmen with rich experience, they have been made after repeated attempts under Li De's extremely strict requirements. The quantity is not too large, and they are very particular when used, and they can't just apply it.

"Young Master, what should I do if the remaining fish in the kitchen are too large? It is estimated that I will not be able to finish it in a few days." Li Fu walked to Li De and asked.

Li De thought for a while and said, "Tell the cook to clean the fish, make it into paste, put it in a large bowl of wine to marinate it, and wait for me to go over and make plans later."

Li Fu left with a mission. He knew about the fish glue. Although he didn't know the specific production process, so many fish had no fish bladder, so people had to think about it.

Chen Xuanhua heard what to eat, and came over and said curiously: "Mr. Li, is there something delicious again? What is it?"

Li De was speechless when he looked at this foodie. Since he had eaten stir-frying, he seemed to be unable to get interested in the original boiled and steamed food.

"Of course it's delicious, why do you want to tell you?" Li Dedao.

"Hehe, Mr. Li, Brother Li, just tell me." Chen Xuanhua's attitude changed rapidly immediately, and there was no arrogant attitude.

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

"You, hum, I know who you are. I have one thing in front of you and another behind you. Why don't you talk to my sister-in-law like this?" Chen Xuanhua refuted stubbornly.

"Just think about it, you will know what to eat when the meal is on. Is it useful to be anxious?" Li Decai didn't like her and chose to ignore her directly.

"Brothers of the Lu family, you will be responsible for making the water supply and drainage system next. Any place with wells in the mansion must be connected." Li De ordered.

"Yes." The Lu brothers knew the difficulty of the project, and they would still do things as they were told.

The whole family of Li's family was very enthusiastic about new things. After Li De finished giving the order, the onlookers were still there, and Li De did not let them leave just like that.

New things still have great attraction.

After handling the matter, I arrived at the kitchen and saw a large pot of fish that had been marinated according to his method.

"Big Young Master." The two cooks greeted.

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

Li De made the order, and the two cooks immediately followed suit.

Mix the fish in the large bowl with eggs and flour, and instruct the chef to pinch the fish balls. While pinching, let the fish balls be put into the pot with the water temperature appropriate.

Li De held a big spoon and stirred it gently in the pot. What's amazing is that the fish balls fell into the pot and quickly formed, and the fragrance of the fish floated out of the pot.

The soup base for cooking fish balls is a good thing, and it can be used as broth. Suddenly I thought it could be used for hot pot restaurants. Today, I can try the taste of fish balls hot pot at home.
