I listened to my sister's words today.

After the meeting, the old man walked out of the office building, wrapped his dark gray wool coat around himself, and headed towards the shooting range.

From a distance, one could faintly hear the crisp sound of metal colliding in the wind.

The thick and solemn coat on his body is particularly eye-catching, especially the five dazzling golden stars on his shoulders.

The soldiers we met along the way were still hurriedly carrying out their respective tasks.

But when they caught a glimpse of this special coat and the four gold stars on it, they all stopped in their hurried steps without exception.

They quickly straightened their bodies and saluted the man with the important task with a solemn military salute in a standard and uniform posture.

As soon as I arrived at the shooting range, I caught a glimpse of a green lawn where two people, one big and one small, were squatting and busy.

Various parts were scattered around the lawn, making them very dazzling in the sunlight.

The old man stood there and observed for a moment.

The younger one was holding a thick installation manual and pointing, "No, no, Uncle Yun, this part should be installed here!"

Yun Yiruo was naive yet serious, like an unquestionable little commander.

On the other side, Yun's father squatted on the ground with a frown on his face, holding the parts in one hand and studying them over and over again with the other.

I'm usually quite good at mechanical design, but right now I feel like I don't know where to start.

"Do as you say."

I tried it where the child pointed, and the part actually clicked into place.

But he couldn't hide a trace of embarrassment on his face.

"Haha, I told you so!" Yun Yiruo clapped her hands and immediately turned to the next page of the instruction manual.

"Now install the silencer!"

After a lot of trouble, the two of them finally installed the silencer.

But this thing is different from the traditional spiral installation method.

Father Yun was in a panic for a long time before he realized that the interface of the silencer was actually a snap-on type.

It took him two tries to finally get it firmly in place. After installing it, he reached out to adjust the scope.

"Hey? Why isn't the light on?" Father Yun frowned. The indicator light on the top of the scope should clearly be on.

But no matter how he fiddled with it, the contacts on the metal rails could never fit perfectly together.

I tried to fine-tune the position again, but the scope light was still dead.

Just as the two were getting anxious, the old man walked towards them with steady steps, his hands in his coat pockets.

He stood in front, looked at the messy parts on the ground, glanced at Yun's father's tense face, and curled the corners of his mouth, revealing a teasing smile.

"What are you doing? Using the lawn as a battlefield?"

The old man cleared his throat deliberately.

Yun's father and Yun Yiru turned around at the same time, and when they saw the old man, the expressions on their faces were completely different.

Father Yun looked like a student who had been caught.

"Why are you here so soon?"

Yun Yiruo fluttered his short legs and ran over: "Uncle! Look at this, Uncle Yun is pretending wrong!"

The old man smiled and picked up Yun Yiru, then looked at the scattered parts on the ground and shook his head meaningfully.

He casually took the scope from Yun's father and tried to adjust the contact position.

With a "beep" sound, the indicator light on the sight suddenly lit up.

The old man raised his eyebrows and handed the scope back: "It still has to be me."

The corners of Yun's father's mouth twitched, and he was about to speak when he heard Yun Yiruo cheer: "Uncle is the best!"

The old man laughed twice, put the briefcase in his hand on the ground, put the child on it, and then patted Yun's father on the shoulder: "Alright, hurry up and clean up, don't let people laugh at you."

Yun Yiruo sat aside, her legs dangling back and forth, reading the instructions and commenting from time to time: "Uncle Yun, this bracket seems to be snapped on too..."

Father Yun was stunned when he heard this. He picked up the bracket next to him with half belief and half doubt, and looked at the interface carefully.

He glanced up at the manual again and muttered, "Why are all these things changed to snap-on types? Even screws are not needed anymore?"

As he spoke, he tried to align the bracket with the interface, pressed it lightly, and with a "click", it was installed firmly.

"Right, I'm right, right?" Yun Yiruo shook his legs proudly and held up the instruction manual in his hand like a little military advisor.

The old man also squatted down, picked up two parts from a pile of parts, made a few simple gestures, and actually put them together accurately at the buckle.

He pressed it gently again with his hand, and heard a series of "click" sounds, and the several parts were perfectly put together.

Father Yun was stunned: "How did you see that?"

The old man stood up, dusted off his hands, and said with a smile, "It's just experience, young man."

Yun Yiruo watched the old man's movements with eyes full of admiration: "Uncle is so awesome!"

More than ten minutes passed.

"Okay, it should be fine."

Father Yun closed the casing again, looked at the finished work, and breathed a sigh of relief.

Seeing this, Yun Yiruo clapped her hands excitedly: "Success!"

The old man looked at the gun that was finally assembled and nodded: "Not bad, now it finally looks decent."

Then he raised his wrist to check his watch, "But to be honest, your efficiency isn't very high."

Before Father Yun could refute, Yun Yiruo had already thrown herself into the old man's arms, holding the instruction manual, and said with a grin, "That's because Uncle Yun is stupid!"

"If uncle had helped us earlier, we would have installed it long ago!"

"Hey!" Father Yun couldn't help but protest, "I installed most of it, okay?"

The old man laughed heartily, picked up the child and placed him on his shoulders: "Okay, now that you're ready, let's get started."

………Dividing line……..

Jiang Ling had just belittled all his men, his voice as cold as an ice knife. "Such a simple design turned out like this? Did I keep you guys here to hold us back?!"

The person next to him lowered his head, cold sweat on his forehead slid down his temples, and he didn't even dare to breathe loudly, as if the air had solidified.

The entire design studio was silent, with only the intermittent sound of keyboard tapping.

"Go away!"

Finally unable to bear it any longer, his tone was already filled with anger, and he directly pulled the designer sitting in front of the screen to his feet, "Do you even know how to use your brain?"

"After twenty minutes, I didn't even produce a finished document."

Fingers moved swiftly on the keyboard, and the mouse jumped precisely between various tools, as if time and efficiency were tightened to the extreme.

After a few minutes, the design on the screen finally took on its complete shape.

He turned around and glanced at the shocked crowd, then said coldly: "Remember, it's not that I don't trust you, it's you who have shown me through your repeated failures that you are not worthy of trust."

The printer finally started working, but the only sound in the entire 3D printing room was the sound of the printer's gears. No one dared to breathe, as if they were afraid of alarming the owner's anger and causing it to erupt again.
