Start with a blacksmith shop.

A few days later, he had also processed the parts needed for the renovation of the old production line.

All that's left is to wait until Sunday to give the workers on the old production line a day off.

I believe one night is enough time for him to make the changes.

Of course, he shouldn't do it all by himself; he still needs help.

The old production line continued to run for the next few days, but the night shift workers were not allowed to come to work after the weekend afternoon shift ended.

He and a few workers worked on the old production line, and in just four hours...

After replacing all the new parts, the production line was revitalized once again.

With his assistants' work completed, it was now his turn to make his move.

With the cheat code in place, all the problems were exposed and solved under his guidance.

Not only did he solve the problem, but he also adjusted the precision of the production line to its optimal state, which is the precision he can currently achieve.

By the time he finished debugging the production line, sunlight was already streaming into the workshop through the windows.

I never imagined that a night would pass by so quickly.

After waiting a short while, the workers on the early shift arrived at the workshop on time.

Because the production line was upgraded, the number of workers needed has decreased.

Under the arrangement of the workshop team leader, workers were assigned to each workstation on this production line.

As for the workers who didn't go online, they didn't have any other emotions.

Because they all know that the company is in the process of ramping up production, they are not worried that the company will lose their positions.

The production line has restarted, and all the workers on the line have felt the power of technology.

They have less work to do compared to before the renovation, but their wages haven't decreased.

While they were busy on the production line, at the aircraft manufacturing plant far away in Hongdu,

A light fixed-wing propeller plane is parked on a short, straight runway.

This is a relatively small aircraft, only eight meters long and three meters high, with a wingspan of eleven meters on each side.

The aircraft has a cantilevered low-wing wing structure and a retractable tricycle landing gear.

Each of the two wings is equipped with a landing gear, and there is also a retractable landing gear under the nose.

Near the fuselage, about one-third of the way down the wing, there is an oval-shaped engine nacelle, and each engine nacelle is equipped with a propeller.

The presence of a propeller clearly indicates that an engine has already been installed in the engine compartment.

On the runway, in the location of each of the two engine compartments, there is a fixed ladder truck.

Several old men were standing on the ladder, their heads sticking out of the open engine compartment, conducting a final check on the engine inside.

"Old Yan, I've finished my check-up here, and there are no problems. How's it going on your end?"

A voice came through the fuselage, and when Lao Yan heard it, he also pulled his head back out of the cabin.

"I've finished my inspection here. The engine is in good condition. Close the engine compartment. Now it's time to hand it over to the test pilot."

The old men on both sides simultaneously closed the engine compartment door, locked it tightly, and stepped down from the ladder.

The two groups of elderly men joined together and walked towards the temporary control tower next to the runway.

Meanwhile, a small ladder truck, converted from a golf cart, drove down from the side of the plane.

At the makeshift open-air control tower, Old Yan came over and checked the communication equipment one last time.

After the inspection, he looked at the test pilot standing to the side. The test pilot was wearing a flight suit, and his rank indicated that he was a lieutenant.

"Lieutenant Wang, this test flight depends entirely on you. Remember, your safety is the top priority."

If anything seems amiss, contact the ground immediately.

And if things get really bad, just parachute out. Don't risk your life for a civilian plane!

With a serious expression, the white-haired old man, Mr. Yan, gave instructions to the young test pilot beside him.

The test pilot, who was at most twenty-seven or twenty-eight years old, nodded to Old Master Yan with a relaxed expression.

"Don't worry, Chief Engineer Yan, I have faith in your skills."

You old gentlemen were all designers back in the day, and this little gadget...

"How could I not understand this? I know exactly what I'm doing."

The old men, hearing the compliment, also wore expressions of pride.

But they still had to say what needed to be said, and then an old man spoke up.

"Young man, let me explain the basic data of this aircraft to you again, so you can have a better understanding of it."

This aircraft has an empty weight of 1439 kg and a designed maximum flight altitude of 5000-6000 meters. You'll have to test it yourself to reach that maximum altitude.

The aircraft is equipped with two seven-cylinder radial engines, which, after our adjustments, can provide a total of 300 horsepower.

However, this power cannot be unleashed under normal circumstances; it requires pressing a button on the dashboard. The maximum power output under normal conditions is only 220 horsepower.

These are the specifications provided by the engine manufacturer when we received this engine.

Remember not to press that button carelessly; pressing it will shorten the engine's lifespan.

The old man spoke in detail, and Lieutenant Wang listened attentively, writing down all the information about the aircraft.

After the old man finished speaking, Lieutenant Wang walked towards the plane under the watchful eyes of many old men and staff members present.

Lieutenant Wang walked to the plane and yanked open the cabin door.

The hatch slid open to the rear as Lieutenant Wang pulled it, and then a retractable ladder was lowered from the fuselage.

Lieutenant Wang was quite surprised to see this; he hadn't expected there to be such a retractable ladder.

What he didn't know was the original design intent of this aircraft.

Designed to compete in the international small private jet market, this retractable ladder is only considered standard equipment.

I climbed the stairs, squeezed through the cabin door, and boarded the plane.

Turning to look at the hatch, I pressed a button, and the retractable ladder automatically retracted.

He then closed the hatch again, locked it, and sat down in the driver's seat.

The aircraft uses a domestically produced flight control system, but because this aircraft is an experimental model, all the button functions are written in Chinese.

He was very familiar with the flight control system, and after looking at a few parts, he started operating it on the instrument panel.

After pressing a few buttons on the instrument panel, the flight control system screen displayed a self-test in progress.

After the self-test was complete, Lieutenant Wang pressed the start button.

Just as he pressed the button, the propellers on the outside of the plane's wings started spinning.

The propeller first slowly rotated a few times, and then began to rotate continuously.

Lieutenant Wang stared straight ahead in the cockpit, waiting for the sound of the engine, but he couldn't hear it no matter how long he waited.

Only then did he look down at the instrument panel, and saw that the two gauges displaying the engine speed showed that the engine was running at idle speed.

Then he discovered that the engine had already started successfully.

However, inside the cabin, the engine was completely silent.

Lieutenant Qi Wang, who seemed somewhat a bit eccentric, opened the small window next to the driver's seat.

When the small window opened, the faint sound of the engine reached his ears.

"Okay, putting everything else aside, the engine noise reduction is really well done!"
