Half a month later.

In the martial arts hall, Li Lin had just finished practicing Cunquan.

I have to say that [Cunquan training methods] is very useful for everyone to practice Cunquan.

In addition to moves, it has special methods for each move of Cunquan, as well as strength and physical fitness training, so you just need to practice with the introduction in the book.

Although the core members have only practiced for more than half a month and it seems that they have not achieved much results at the moment, he believes that there will definitely be qualitative changes in a year and a half!

"Master, Miss Defne's letter." A subordinate's voice came from outside the door.

"Take it in."

"yes."

After receiving the letter, he opened it and saw that the content on it was about the sales of No. 5 perfume.

According to Defney, the No. 5 perfume was put on sale after many of her perfumes were put on the shelves, and after those noble customers smelled it, they all fell in love with this perfume!

Sales are currently very popular. These days, people are queuing up to buy them every day!

Finally, the letter ended and wrote that every month, you will need to provide 20,000 bottles of perfume.

"Tell my cousin that they will ship 20,000 bottles of perfume to Miss Defney every month in the future." Li Lin said.

"yes!"

...

afternoon.

Li Qiang ran in excitedly: "Xiaolin, all the parts of our engine are ready, and several mechanics are about to install it. Do you want to go over and take a look?"

"Can you install it?" Li Lin was overjoyed after hearing this.

"right!"

"Go and go and take a look."

Soon the two of them arrived at a workshop covering an area of ​​300 square meters. This place was a house he rented and was converted into a simple workshop.

"Hello, boss!" Several mechanics in the workshop said hello when they saw their boss coming in.

There are three mechanics in total, namely Colin, Derek and Keno.

All of them were invited by Li Lin for a lot of money. They used to work in some large machinery factories, worked as designers, or senior manufacturers.

Li Lin looked at it and found that except for the engine cylinder block, most of the other parts were hand-polished by the three of them.

"Well, have you started to install it?" Li Lin asked.

"Installation is being done, if it is fast, it should be able to be completed tonight." Keno introduced.

"Okay, you guys install it, I'll just take a look."

"Yes, boss."

All three of them started to install it one after another.

Li Lin looked at it and found that the three of them were installing the cylinder block and installing the crankshaft connecting rod and other things in it.

One afternoon, I quickly passed by, looked at it, and installed most of the parts.

After dinner, continue to install it.

It was almost nine o'clock in the evening in a flash and the installation was finally completed.

"Only the last step is left, pour in the engine oil and add fuel, and you can try to start it." Li Lin looked at the engine in front of him, feeling a little moved.

If it is really successful, then the plan to build an airplane can be officially put on the agenda.

Colin started pouring oil in.

After the three of them checked each other, Derek said to Li Lin: "Boss, you can try to start!"

"Okay, start!" Li Lin ordered.

Start ignition!

Twist...

The engine began to shake, and a smoke was discharged from the exhaust port.

But the next second, the engine stopped ringing.

"No ignition was successful? Continue!" Li Lin said.

When I ignite the fire again, it was still a burst of smoke.

"Continue!"

Twist!

Rumble...

Finally, the ignition was successful!

The engine is running normally!

"Success, success, boss, we succeed!" Colin said with some trampling.

Although this engine was not designed by them, they participated in the manufacturing and they also felt an inexplicable excitement and pride.

After all, there are almost few fuel engines these days, and even those car engines are very few.

Those who can make engines are world-renowned mechanics, which is also the dream of the three of them to become famous.

Today, they witnessed it all!

"Huh... it really succeeded." Li Lin couldn't help but breathe a sigh of relief when he saw this.

Since the engine is successful, it will definitely shock the world when he builds the plane!

Nowadays, everyone wants to fly into the sky like a bird!

"Let's get the throttle up and see!"

Come on, boom boom boom!

The engine's sound became louder and louder, and the shaking became more and more violent.

"The horsepower of this engine beats the current engines of those cars!" Derek said excitedly.

"Yes, if you install it on a car, the speed... tsk, I can't imagine it!"

"Boss, I think you can open a car company, which is definitely much better than the current Mercedes-Benz car!"

Li Lin smiled when he heard this. The two of them thought he wanted to build a car?

Haha, this is the aircraft engine!

"I'll talk about this later!"

At this moment, Keno suddenly exclaimed: "No, the engine oil pan seems to be leaking oil!"

As soon as this sentence came out, everyone gathered around to watch.

It doesn't matter when you see it, but it's shocked.

The oil pan indeed saw oil seepage!

"Didn't wipe it clean just now?"

"No, I clearly wiped it clean just now." Keno said as he quickly took a towel and wiped the oily area. Sure enough, within a few seconds, oil seeped out again.

"Switch off the engine, it seems that our engine is not really successful!" Li Lin shook his head.

"Boss, the problem of oil seepage must be solved, otherwise it would not be a successful engine!"

"There will be a long time to test the engine in the future to see the various durability data, etc.."

Several mechanics began to analyze it in one word.

"I understand this. If you remove the development engine and see what the problem is, oil leakage. Oh no, it's too late tonight, so let's continue tomorrow." Li Lin shook his head.

He was not very disappointed with the engine oil leakage.

After all, even if the engine is made according to the design drawings, as long as some parts are not qualified or the steel is not good enough, it will cause various problems.

The first time it was assembled and started successfully, it was the greatest success for him!

The engine is a very complicated thing. If you can succeed for the first time, you will be really a ghost!

The next day, Li Lin came to see again, but the three mechanics did not find any problem on this day, and what was the problem?

On the third day, a problem was found, and the oil leakage was caused by insufficient accuracy of a certain part of the oil pan.

After the solution, a few days later, the engine was speechless and innocently unable to start.

When I took it apart, I found that there was another problem with the valve gasket...
Chapter completed!
