Because it was a holiday, the school seemed a little deserted with few students early in the morning.

Lu Yuguo went directly to the repair building.

I received a bunch of tools from the uncle who was guarding the tools, and then opened a separate repair room.

Fortunately, the school is on vacation, otherwise it would be really difficult to find a separate restoration room available. Even now, many restoration rooms are still occupied.

The two of them entered the restoration room. Lu Yuguo closed the door, glanced at the equipment in the restoration room, and nodded with satisfaction.

He put away his toolbox and backpack, and as he took out a selfie ball from his bag, he said, "Fu Zhongji, just put the wood on that workbench."

Mo Yuanshen looked around the restoration room, then placed the large piece of wood on the workbench next to it.

He said, "Is there anything I can help you with?"

"Not for now, just stay here." Lu Yuguo connected his terminal to the selfie ball without even looking up, and then set up the settings for video shooting and follow-up shooting.

He wanted to film the process of making the pipa. If the pipa was successful, the video would not only be commemorative but also serve as evidence.

Lu Yuguo walked around the restoration room with a selfie ball.

After checking the shooting angle on the terminal and adjusting it, he put on his work apron and started to get busy.

He had been busy the entire morning, but had not yet actually started making the pipa. He was just measuring the wood and making templates of various sizes.

He only had a piece of wood and couldn't afford to be too delicate.

At lunchtime, when Mo Yuanshen ordered food to be delivered to the repair room, Lu Yuguo stopped to rest.

The two of them sat down on the sofa to rest. Lu Yuguo helped open the fast food packaging while looking at Fu Zhongji and asked, "Aren't you bored?"

"Not bad." Mo Yuanshen raised his hand and shook the terminal and said, "I'll chat with you occasionally. When you're busy, I can also play with the terminal."

"It might be noisy when I start cutting wood in the afternoon," Lu Yuguo reminded.

"Well, don't be polite to me if you need my help." Mo Yuanshen said.

Lu Yuguo nodded, said nothing more, and continued to work after dinner.

After marking every part of the rosewood and checking it again to find no problems, Lu Yuguo carried the wood to the cutting machine, turned it on and cut out the general outline of a pipa backboard.

In his previous life, he worked in a musical instrument factory and was skilled in the craft of making pipa backboards, so he was quite familiar with it compared to other parts.

When he heard the sound of the machine starting up, Mo Yuanshen felt a little worried and went to watch from the side.

The machine made a sharp "squeaking" sound when cutting wood, which was very harsh. When he saw Lu Yuguo's little hand holding the wood close to the saw teeth, his heart was lifted.

Although the cut was a rough outline, Lu Yuguo was still very careful for fear of destroying the shape.

I pushed it carefully bit by bit, and it took almost ten minutes to complete the cutting.

After turning off the cutting machine, Lu Yuguo glanced at Mo Yuanshen and said with a smile, "It seems that you are more nervous than me."

How could he not be nervous? What if that tender little hand got cut? Mo Yuanshen didn't dare to think about it, it made him feel heartbroken.

Lu Yuguo smiled and shook his head, placing the rough wood on a fixed table.

He used fixing tools to fix the wood, then found a hammer and a curved chisel, and then started to chisel the inner hall of the backboard.

Originally, Lu Yuguo wanted to use a machine to cut the inner hall of the back panel, but there was no such special machine in the restoration room.

Other machines require setting various data and parameters of the pipa. He was afraid that he would make mistakes in setting the data and parameters, after all, he was not a professional.

So he had to do it himself. At least he was familiar with handmade products and he felt more at ease.

Carving the inner hall was a laborious and tedious task. Lu Yuguo chiseled bit by bit, checking after every few strokes.

He had never been so meticulous when he was working at the piano factory before. Perhaps this was the difference between making something for himself and for others.

"Let me help you."

Mo Yuanshen was worried and kept watching from the side. He felt that this was not a difficult physical job and he thought he could help.

"No need." Lu Yuguo looked up at him and said, "I'm afraid your strength will split my material."

Mo Yuanshen smiled and said, "I have a relatively good control over my strength. Let me try."

Lu Yuguo looked at him with a hesitant expression. Mo Yuanshen knew that he was worried, so he continued, "You can watch from the side and direct me."

"Okay, then try it with those materials first."

Lu Yuguo pointed to some small pieces of wood nearby and handed the hammer and chisel to Fu Chongji. He didn't dare let Fu Chongji try his hand with his materials.

Mo Yuanshen imitated Lu Yuguo and tried for a while. His control was much more careful than Lu Yuguo's. He asked, "Is it okay?"

Lu Yuguo didn't expect that he chiseled it quite well, so he nodded and said, "It should be pretty good."

He said this, but when Mo Yuanshen started working on the rosewood, he still stood by and directed him.

The inner hall of the pipa back is the most important position for sound and resonance, and it is very important to choose where to chisel deep and where to chisel shallow.

In order to avoid mistakes, Lu Yuguo marked the size and depth on the wood. He said, "Try a few times as I did before."

Mo Yuanshen nodded and tried to chisel the edge a few times like Lu Yuguo did, which felt pretty good.

He chiseled a few more times, then turned to look at Lu Yuguo and asked, "Is this ok?"

"Okay, keep going."
