"Hui Gongzi, as in previous years, the scorching heat is coming, and it is also the off-season of the restaurant. It's just early summer, and business has dropped dramatically. Many guests are not tolerant of hot food in the building, and the large number of people in the building adds to the heat and boredom. Lin Youyou reported the situation of Jinfeng Building.

"Hmm" Wei Yun replied and said no more.

Lin Youyou asked, "Childe wants to pass the meal?" ”

"Shopkeeper Lin, I heard that the chef in the building has newly developed a 'sea cucumber stewed hoof tendon' in the capital, and the son wants to taste it in the capital, so I will serve this dish to the son today!" Wei Fu, the little guy next to Wei Yun, said.

"Okay, the old slave will arrange it immediately." Lin Youyou blessed Wei Yun and retreated.

After a while, hot dishes were served. The first is the 'sea cucumber stewed hoof tendon', looking at the dishes that exude boiling heat, Wei Yun is also a little appetizing.

After a few quick sips, he sent someone to withdraw.

Wei Yun motioned for Lin Youyou and Wei Fu to sit down, and the tip of his index finger lightly pressed the tabletop, making a gurgling sound. Wei Yun put the ledger that Lin Youyou picked up in front of him, flipping through the pages one by one, and for a while, there was only the sound of the fingertips tapping the table and the ledger flipping through the room.

Ling Mengqi and the three of them were sent over to scrub the carriage with Huang Dazhuang, the space in the carriage was very large, lying horizontally and vertically, there was a fixed square table in the middle, and the table was surrounded by soft cushions, as soon as you got into the car, you could feel a slight coolness, and after a closer look, you found that there were still some unmelted ice cubes in the stove in the four corners.

What a rich man's life! This carriage is comparable to a modern Mercedes-Benz BMW!

Ling Mengqi took the cushions out one by one to dismantle and wash Aunt Lin Zhang Danian, she was responsible for scrubbing the carriage, and Huang Dazhuang was responsible for brushing the horses. Several people work together.

Ling Mengqi was going to rinse the wheels of the car directly with water, and washed the sand and gravel off the wheels.

"Eh, Xiaoqi, what are you doing squatting there? Is the carriage washed? Aunt Zhang and Aunt Lin finished dismantling and washing the cushions, and planned to come over to see if Ling Mengqi needed help here, but when she got closer, she found that she was squatting next to the wheel, her little hands pulling stones on the ground.

Ling Mengqi turned around when he heard the voice, and held up a large stone in his hand to show Aunt Zhang and them: "Auntie, what kind of stone is this, how can it still melt, it's not the same as what I usually see!" ”

Ling Mengqi once saw a report on the use of saltpeter to make ice in history, and she thought it was amazing at the time. She was a little suspicious that the saltpeter in her hand could be used to make ice, so she wanted to ask Aunt Zhang and Aunt Lin if they knew about this thing.

"What's this?" Aunt Zhang squinted her eyes and carefully glanced at the stone in Ling Mengqi's hand several times, and said suspiciously: "The stone that will melt like this is not used!" If you use it to build a house, you can't collapse when it encounters water! ”

Ling Mengqi looked at Aunt Lin, she also looked like she had never seen it.

Ling Mengqi had to wait until he was sure before asking the coachman, and heard that they would stay here for a while. She picked up the large stones that were left on the ground and put them in the tub, and went under the carriage to see if there were any such stones embedded in the axles, and buckled them down.

Placing the wooden basin aside, Ling Mengqi quickly finished washing the carriage and planned to do her experiment. She was going to sell this recipe to Wei Yun if the experiment was successful, otherwise relying on her monthly salary, she might not be able to save the start-up capital for the business!

Recalling the reports I read in my previous life, fortunately, the process of making ice from saltpeter is simple, and as long as you grasp the proportion, you can make ice cubes.

Ling Mengqi took out the saltpeter from the wooden basin and put it on the dry door, poured the wooden basin with water, put a small wooden basin filled with water in the middle, and then put some saltpeter into the wooden basin, waited for a while, if the water in the small wooden basin was not frozen, then continued to add saltpeter to the wooden basin.

When Ling Mengqi thought that it might not be saltpeter, she was surprised to find that the water in the small wooden basin had finally turned into ice, and a small bowl of ice had used up almost all the saltpeter she had picked up.

Ling Mengqi picked up the ice in the bowl and continued to place it in the wooden basin, while he took the remaining small piece of saltpeter to find the coachman Wei Dayou.

"Uncle Otomo, take advantage of the cold!" Ling Mengqi sat next to Wei Dayou and picked up a fan to fan him: "I'm Xiaoqi, a dishwasher in the backyard, and I just picked up such a stone when I was cleaning the carriage." After that, he took out the saltpeter and showed it to Wei Dayou: "Does Uncle Dayou know where this stone came from?" ”

Wei Dayou opened his originally squinted eyes and glanced at Ling Mengqi, who was smiling, before picking up the stone in her hand: "I'll take a look"

Wei Dayouzai looked at it carefully and said, "I really don't know this, but I should have brought it here on the way." Little girl, is there anything special about this stone? ”

"No, just ask, I think it's pretty beautiful, it's the first time I've seen a stone like this!" Ling Mengqi shook his head with a smile, fanned Wei Dayou hard, and continued to ask, "Uncle Dayou, where are you from?" How long does it take to get here? ”

Seeing Ling Mengqi sweating profusely, Wei Dayou was embarrassed to let Ling Mengqi fan herself with such a little girl, so he took the pu fan in her hand and shook it himself, Ling Mengqi sat in the first place under him, and this direction was just able to rub the wind from the pu fan in Wei Dayou's hand.

"If you come from the capital, you will have to go up for almost two days on the official road!" After speaking, Wei Dayou leaned his back against the beam, squinted his eyes and began to nap. Seeing this, Ling Mengqi didn't want to disturb him anymore, jumped off the edge of the wall and staggered to find Lin Youyou.

"Brother Dagen, has the shopkeeper come out?" Ling Mengqi quietly went up to the second floor and asked softly to Wang Dagen, who was standing outside waiting for the dispatch.

Wang Dagen shook his head and replied softly: "No! It's quiet inside, and I don't know what I'm doing! ”

"Oh oh" Ling Mengqi stretched out his head and glanced at the closed door, and said in his heart: When Lin Youyou comes out, my ice will have to melt too!

Wang Dagen looked at the small bowl held by Ling Mengqi curiously: "Hey, are you holding ice?" ”

"That's right!" Ling Mengqi's eyes rolled, thinking, or he might as well lure them out louder. After thinking about it, he handed the bowl to Wang Dagen: "Brother Dagen, let you hold it too, dip it in the coolness, how about it, isn't it cool?" ”

"Cool and cool, where did this ice come from?" Wang Dagen stared directly at the bowl of ice in his hand, looked at the faint cool air emanating from it, and sighed with satisfaction.

"I did it myself, didn't I?" Ling Mengqi listened attentively to the house inside, which didn't even have the slightest movement at the end of the book, and raised his voice a little more.
