After walking out of a certain distance, he made a gesture. Jia Youcai quickly shouted a few times. The voice was not enough. Qin Huaidao returned and looked at the stage and pondered. The foreman said carefully: "Master Qin, the craftsmen are his ancestral skills. It should be fine to work for the palace. The sir was standing a little far away just now, beyond the norm. I heard that the sir is proficient in investigating things and manufacturing. If you have any dissatisfaction, please mention it and let us change it immediately."

Qin Huaidao's eyes fell on the base of the stage. The hollowed-out part of the four walls was still made of blue bricks. It was also exquisite. He moved his heart and possessed himself. He saw the big jar inside from the hollowed-out position. He had an idea in his mind and immediately asked, "Are you?"

"Sir Hui, Xu Laosan, is a labourer."

"Xu Laosan, the stage is done well, but I need some adjustments in some places. Can this big cylinder be drilled?" Qin Huaidao asked bluntly.

"able!"

"That's good. Remember, all the holes drilled towards the hollowed-out position are the size of eggs, three rows, three in each row, up and down, one nine, and the same distance between each holes."

Xu Laosan quickly remembered it and agreed: "If you do this, you will leak a little, but the adults ask that the younger ones make arrangements immediately and do it today."

"The large cylinder can store sound and form a bass resonance effect, but it will also cause the sound to be too low and not easy to distinguish. Some sounds will be thick and clear when leaking. In addition, it is necessary to create a loudspeaker to amplify the sound and spread it far away." Qin Huaidao explained.

When Xu Laosan heard this, his eyes shone. He realized that there was a technical problem here. Once he mastered it, he would benefit greatly in the future. He quickly asked: "Sir, what is a loudspeaker? Can it be taught here?"

"What's wrong with this? Come with paper and pen." Qin Huaidao said indifferently.

Soon, Xu Laosan brought paper and pen, Qin Huaidao dripped a trumpet, marked the size according to the size of the stage, and explained to Xu Laosan who was watching: "Made of thin iron sheet, the small end is connected to the hole of the large cylinder, and you can wrap the periphery with cloth and seal it. The large section extends out from the entrance of the building, don't be too long and sticks to the wall, otherwise it will not look good, and install one for each large cylinder."

The two speakers on each wall are enough to amplify the sound, and there are eight on four walls, which is enough to spread the sound far.

Xu Laosan looked at the speaker a little confused. Such a simple thing can spread the sound far away and solve the problems of eternal success? But when he thinks of the magic of folk legends about Qin Huaidao, such a big figure is a stage for himself, he doesn't have to be happy with himself.

Regardless of whether it can be done or not, you can tell it after a try.

If it works, wouldn’t I have mastered a magical technique? Thinking of this, Xu Laosan was not calm and kept saying, “Sir, I’m going to make arrangements here, are there anything to pay attention to?”

Qin Huaidao thought about it and reminded him: "First use wood to make a mold of the same size, then put it on the iron sheet and beat it to ensure that each one is of equal size and the surface is smooth and smooth, otherwise the sound will be uneven. Secondly, the joint parts of the iron sheet are burned red and then knocked together to form a whole, without gaps or holes. After all, carburizing and increasing the hardness can ensure the sound resonance and brightness."

When Mr. Xu saw Qin Huaidao telling each other the key points, he was overjoyed and said gratefully: "Mr. Xie is willing to give me advice. I will keep this secret and will not be passed on."

"It's okay to spread it out. Only by mastering the technology can we make progress together. Create ten more for the official to spare, just to teach you how to create the rewards, is it good?"

Mr. Xu was very happy and said excitedly: "What are ten? Create twenty more, no, one hundred more."

"No need to have that much, okay, do it as soon as possible." Qin Huaidao waved his hand and signaled Xu Laosan to leave. He reminded Jia Youcai: "Have you bought the furniture for food yet?"

"No, just wait for the young master to decide."

"It's good if you didn't buy it. I've drawn some sketches and you can take it to the mansion to make it yourself." Qin Huaidao said as he took out a drawing from his arms and handed it on it. It was a table and square stool drawn last night. It was simple, convenient and easy to use.

Jia Youcai took it over and saw that the things on it looked strange and had never seen them before. However, after seeing Qin Huaidao's magical skills, he did not question it and quickly put it away. Qin Huaidao asked, "Come with me."

The two of them came to a row of wing rooms next to them, and the inside was cleaned. Qin Huaidao said: "Break the wall in the middle and open it up. The two rooms are connected together to make a kitchen. You also need to create some barbecue racks. Let the drawings come back for you. Dig a large cellar in the next room for later use, build the wall with cement and bricks, put more cement to prevent water and moisture."

After Jia Youcai agreed, Qin Huaidao led him around to see where to set up tables in the future, where to hang lanterns, where to add a stone road, where to plant some bamboo, what door signs to hang in the private room, and how to keep numbers on the table to make a table number, all explained carefully before leaving.

The shop was not far away. Qin Huaidao went over to take a look and saw that there were many people queuing up, and the business was good, and no one caused trouble. He left quietly and returned to the mansion to teach everyone to make wine and sing.

The revenge between the Lu family of Fanyang and Fengyulou may break out at any time, so we must hurry up and arrange the necessary matters.
