"How can I process this diamond, oh, diamonds should be processed into many cut surfaces, which is good-looking." Qian Xiaoxing thought that ancient times were really a waste of resources.

"Oh, Brother Qian knows how to process it? Tell me quickly." Ling Yi asked hurriedly when he saw Qian Xiaoxing talking.

"The simple one is eight arrows and eight stars. This is the most common method of processing diamonds. Are there pens and paper? Oh, it's white silk, I'll draw it and you can see it." Qian Xiaoxing thought about the most common appearance of diamonds, a sharp cone with a lotus mount at the bottom.

"Okay, okay, go to the study." Whenever Qian Xiaoxing wanted to draw something, Ling Yi knew that something new was about to appear and said anxiously.

Everyone walked to the study together. Qian Xiaoxing picked up a quill and a ruler, and drew it on the white silk. The eight arrows and eight stars are still simple. There are eight sides on the cone and eight sides on the base. The bottom plane is an octagonal shape. After a while, a three-dimensional diamond eight arrows and eight stars were drawn.

Ling Yi picked up the picture and looked at it. Qian Xiaoxing had more pictures, and he was familiar with the three-dimensional painting method. He understood it at a glance and said, "Brother Qian, are you saying that this diamond is to be processed into this shape?"

"Yes, but not every need to do this. The more sections the diamond needs to be processed, the better. You can also design according to the shape of the diamond itself." Qian Xiaoxing explained.

"Oh, what are the benefits of processing so many sections?" Ling Yi asked in confusion.

"I won't talk about this for now. I'll choose a suitable diamond later. You can process it first and make an eight-arrow and eight-star out first. You will know then." Qian Xiaoxing said with a silence.

"As long, I will let someone process it as soon as possible." Ling Yi was even more curious when he heard Qian Xiaoxing say this. Every time Qian Xiaoxing makes something new, and never disappoints everyone.

When everyone returned to the hall, Qian Xiaoxing chose a soybean-sized one, which was about the same shape as the eight arrows and eight stars, and gave it to Ling Yi: "Just use this one, the shape is similar. Also, if Brother Ling sees diamonds sold in the future, he will buy them for me. If you don't want me, I want it, haha."

"Well, I will ask the jewelry store owner to buy it when I see it, but what's the size? Is it okay to be too big?" Ling Yi asked.

"Big? The bigger the better, don't be afraid of being big."

At this time, the servant reported that the meal was ready, and Ling Yi led everyone to the dining room to sit: "Home-cooked meals, please do whatever you want."

Qian Xiaoxing looked at it and it was already full of the table, very rich. He was not polite, so he picked up the chopsticks and started eating. He only ate two boiled eggs in the morning, but he was so hungry.

Everyone also started to eat. The chef hired by Ling Yi’s family was obviously good at craftsmanship, and everyone praised the food.

After everyone had a meal, Fang Ying asked Qian Xiaoxing: "Did you hear that Lei Hu are there in court this time?"

"Lei Hu? I haven't heard that they all call each other's official destiny and don't know how to name them." Qian Xiaoxing thought for a while and said.

"Miss, Lei Hu should be guarding the border now, not in Shandu." Butler Lu said.

"Oh, I just asked casually."

Qian Xiaoxing looked abnormal after seeing Fang Ying's words, and probably thought of something unhappy. When he went to court today, he heard that the general said that many soldiers had died in attacking Si State five years ago. Is this general the Lei Hu the one in Fang Ying's mouth? However, seeing Fang Ying is so depressed, it is better to mention it less. Even if Fang Ying knows, what can he do?

During the meal, Qian Xiaoxing also told Ling Yi about the installation of two air conditioners in the Taifu Mansion, pointing out that the income from the air conditioner of Qian Lingyi was released, but when Ling Yi heard this, he refused to agree, saying that he always went to Fang Ying's house to play mahjong, and there was much harassment, and he would not accept the money to death.

Alas, Qian Xiaoxing has nothing to say about such a money-loving owner, so he can only say good brothers. However, I remembered that I have installed a lot of air conditioners recently, but I have never calculated it. Because I was too relieved about Ling Yi, I asked: "Brother Ling, how many air conditioners have we sold so far?"

When Ling Yi heard that the boy wanted money, he ordered his servant to bring the account book, and looked at it and said, "So far, a total of 24 air conditioners have been sold, and there are 42 reservations, of which eight are housed in a restaurant. The money has been settled for you. If the remaining sixteen are to be shared by Brother Qian, he can be taken away later."

Qian Xiaoxing asked Fang Ying with his eyes, and Fang Ying replied and took it away first. After all, only if the money is on him, he feels safe.

"Okay, I'll take it away later." Qian Xiaoxing was not polite either.

"Well, I'm done, Brother Qian, have you eaten? Go and see the tricycle handlebars with me." Ling Yi had been trying to urge him for a long time, and was embarrassed. He saw that Qian Xiaoxing had almost eaten, so he said.

"Well, I'm still missing the last bite." Qian Xiaoxing reached out and twisted a chicken leg from the vegetable bowl, stood up, and walked out with Ling Yi.

Ling Yi brought Qian Xiaoxing to the back garden next to him. Everyone was full and followed him to see the freshness.

Qian Xiaoxing looked at it and a tricycle was placed on an open space the size of a basketball court. He walked in and took a closer look. The wooden wheels, wooden car buckets, wooden handles, wooden frames, wooden cushions, and only key parts such as pedal links, axles and gears were made of bronze.

Qian Xiaoxing did not rush to test the car, but instead pulled the car down with his hand. The pulling force did not need to be very strong, and it felt quite relaxed. Then he stepped on and stepped on it.

Qian Xiaoxing slowly stepped on a few steps, and the car slowly moved. Everyone clapped their hands and cheered: "It's moving, the car has moved by itself."

When Qian Xiaoxing heard this, he laughed in his heart. It was not the car that moved by himself. It was clearly because I was stepping on it. But thinking about it, in ancient times, in addition to seeing a car pulled by a horse, he had never seen a car without a horse.

Qian Xiaoxing stepped on it faster, and the tricycle became faster and circled around the open space quickly: "Whoever is going to come up and sit down, I will be the free coachman."

"I want to sit down." Fang Ying shouted.

"I want to sit down, too." Lan Xiaocui said.

"I want to sit down, too." Ling Shan said.

Qian Xiaoxing looked at the car dot, which was similar to the modern ordinary tricycle, and shouted: "Come on, give me your first time, huh, I mean the first time I took a tricycle."

The three women joined hands and lifted their skirts and slowly got on the car. There were flat panels on each side of the car. Fang Ying and Ling Shan sat on it carefully. Xiao Cui had no place, so she could only hold their hands and squatted in the car.

Qian Xiaoxing looked at the three women holding the skirt, revealing a white calves, and secretly smacked his lips. In ancient times, women all wore long skirts, and this calves were white. He read that right, Ling Shan's calves were slenderer than the other two women. He couldn't help but think that Ling Shan's appearance in a short skirt must have beautiful legs.

Seeing that the three of them were seated, Qian Xiaoxing stepped on the pedal, stood up and stepped on it. The car slowly moved. As Qian Xiaoxing pedaled hard, the tricycle became faster and faster. After a while, he turned to Ling Yi and Butler Lu. Qian Xiaoxing shouted loudly: "You are the eldest daughter selling yellow flowers. Do you want to buy one?"

Fang Ying and Ling Shan heard this and hit Qian Xiaoxing on the back with their small fists. Qian Xiaoxing held back the pain and continued to shout: "It's very cheap, five cents, and one more is given."

When Ling Yi heard this, he cooperated and said, "Boss, please be cheaper."

"If you really want it, then just cut two more cents. Salmon is cheap enough. I'll give you a price to jump to the house. It's not easy for me to raise them."

"Okay, I'll buy it, I'll give it to my brother Qian." Ling Yi joked.

Everyone laughed for a while after hearing this, but Qian Xiaoxing felt uncomfortable on his back. He was beaten a few times and didn't say it. I don't know who twisted it a few times. Qian Xiaoxing was so painful that he bared his teeth.

Qian Xiaoxing took them around for a few times. After all, the ancient craftsmanship was backward and the resistance was great. It made Qian Xiaoxing panting. He turned to Ling Yi and Butler Lu, and then stopped the car and climbed down.

"Brother Qian, is this car okay?" Ling Yi came up and asked.

"It's done well, but it's hard to ride it once a person is loaded. The friction is too big and it's very laborious." Qian Xiaoxing thought that the ancient axles did not have bearings, and it was completely a friction between wood, and the friction naturally increased when under pressure.

"Oh, then there is a way to solve it?" Ling Yi was a little disappointed when he heard Qian Xiaoxing say this.

"Of course there is a way, but it's a little harder to do. When I go back, I'll draw something for you and put the axle in the middle, and it will be extremely easy." Qian Xiaoxing thought about making some bearings when he was making air conditioners, but he was afraid of it being exhausted. Now, Ling Yi will arrange it, and he just draws a picture, which is simple.

"You, you are going to draw pictures again, okay." Ling Yi felt excited every time he heard Qian Xiaoxing draw pictures.

"By the way, this car has not braked yet, so I will draw it together at that time." Qian Xiaoxing forgot to draw the brake system on the picture he drew last time.

"What is the brake?" Ling Yi asked in confusion.

"Oh, if the car rides too fast, you have to stop urgently, just press it and stop it." Qian Xiaoxing explained.

"There is something like this? It's magical, then go and draw it." Ling Yi pulled Qian Xiaoxing and walked towards the study.

The three girls also got off the car with laughter and said that the car was new and had never been taken. Fang Ying even said that she would never make a carriage again, and that Qian Xiaoxing would take her on the carriage. Qian Xiaoxing couldn't help but feel dizzy when she heard it. She wouldn't have made a tricycle and hurt herself.

Qian Xiaoxing returned to the study and drew the bearing drawings and brake drawings, but Qian Xiaoxing made some changes to the bearing. After all, the ancient craftsmanship was not so developed. After the outer ring and inner ring of the bearing were made, the balls in the middle could not be stuffed in. So a hole was opened in the outer ring, and the balls could be stuffed in through the hole. When the installation was completed, it was pressed against the gap, and the balls would not run out.

Ling Yi looked at the bearing diagram and then understood that the axle passed through the middle of the bearing. When it turned, it turned the ball and the friction was much less. Why couldn't I think of such a simple truth? I could only admire Qian Xiaoxing, and almost elevated Qian Xiaoxing to the level of god in my heart.

"Brother Ling, this bearing is not only for tricycles, but also for your current carriages, etc., and it will not squeak or croak, and it will save more effort when pulling the horse and run faster." Qian Xiaoxing was in the carriage in the morning, and when he heard the squeaking sound, he felt more and more sad. The sound was simply tormenting.

"Brother Qian is right. I'm just thinking about this, so just the old rules are open to five or five." Ling Yi said.

"Success, as Brother Ling said, being a man is under great pressure and having to work hard to make money to marry a wife, but there is a woman who can't get a little money, which is painful." Qian Xiaoxing teased.

"If you feel the pain, don't marry me. Who will force you?" Fang Ying didn't know about Qian Xiaoxing and Ling Shan, so she said.

"It's hard to describe it." Qian Xiaoxing shook his head, afraid that Fang Ying would continue to ask, and asked again: "Miss, if you want to get married, should you choose the person you like or the person you like?"

"What do you think?" Fang Ying never thought about this question before and asked back.

"I think you choose the person you like." Qian Xiaoxing replied.

"Oh, why?" Fang Ying couldn't help but think inwardly, does Qian Xiaoxing know me so well?

"Because... because no one likes you."

After Qian Xiaoxing said that, he flew away. Fang Ying chased him from behind, insisting on catching up with Qian Xiaoxing and teaching him a lesson with his shadowless foot.
