Gu Gu Gu Gu

There was a sound in Sun Xian's stomach, and he nodded sheepishly.

"All right."

Han Du ordered someone to deliver the food, and the two of them

Let's eat together and then go to the laboratory.

When he came to the laboratory, Sun Xian looked at the oil stains on the parts all over the floor. He couldn't help but look shy and scratched his head in embarrassment, "Sir, here"

"It doesn't matter, just be casual." Han Du knew what he was thinking, didn't he just think that he made this place too messy?

Han Du knew that for those who study hard, they would feel extremely irritable once they encounter a problem that cannot be solved. At this time, let alone throwing things away, even if they attack others more fiercely for no reason, or torture themselves.

It can happen to you.

Looking at the pile of parts in the middle of the table, there is nothing inside the round brass shell.

Han Du couldn't help but turned to look at Sun Xian and said in surprise, "You have made no progress at all these days?"

This shouldn't be the case!

According to Han Du's estimation, although it is indeed too big to make a clock so small, Sun Xian is already familiar with all the structures of the clock. Now he just needs to reduce each part and assemble it.

Is it so difficult?

Sun Xian frowned, feeling completely devoid of confidence, and said with an embarrassed look, "I let you down, sir."

"What's going on? Is there a problem with the parts?" Han Du glanced at the parts on the table and raised his eyebrows slightly.

Sun Xian looked a little lonely, shook his head and explained, "Although the parts are difficult, the problems are not big. The students have solved them. However, after making all these parts, trouble arose when starting to assemble them."

“The students have tried many times, but they can’t assemble it!”

The parts cannot be assembled? This problem is a bit strange. Logically speaking, assembly should be the easiest part of making a watch. How could there be a problem?

Han Du looked at it for a moment and couldn't see the problem, so he said to Sun Xian, "Assemble it and show it to me. 0"

"OK!"

Sun Xian stepped forward and sat on the chair, then picked up the brass shell and prepared to start assembling the parts.

Han Du looked at his movements and always felt that there was something wrong. However, he did not say anything because he did not want to disturb Sun Xian.

Sun Xian used his hands to gradually install the parts one by one from large to small. The smaller the parts were installed at the back, the slower Sun Xian's speed became.

Finally, when Sun Xian was installing a very small part, the entire assembled structure collapsed instantly, and all the parts were scattered on the table.

Sun Xian raised his head, looked at Han Du with a wry smile, and sighed, "It's like this every time. The more you pretend, the more careful you have to be. Once you make the slightest mistake, you have to start all over again."

"It's pretty good this time. I can install a few more parts." Sun Xian lowered his head and glanced at the parts on the table. He shook his head helplessly, "It's a pity that it still doesn't work!"

When Han Du saw the parts scattered, he suddenly remembered that he had seen a scene of repairing clocks. Suddenly, Han Du understood what the problem was.

How big are Sun Xian’s fingers when he assembles it by hand? How can he assemble such small parts by hand?

To be honest, Han Du was filled with surprise when he saw that Sun Xian could assemble most of the clock with just his hands.

Seeing that Han Du didn't speak for a long time, Sun Xian thought that his husband was angry, so he lowered his voice and said, "Sir, did the student do something wrong?"

Han Du raised his head and looked at Sun Xian, suddenly laughed, shook his head and said, "No, it's not your problem."
