, The fastest update starts reading the latest chapter of becoming stronger since I am a special soldier!

An hour later, the roar of helicopters came over the military factory.

The helicopters carrying the students stopped one by one and opened the hatch. An Ran and the others jumped off the plane and looked at the surrounding scenes with surprise.

"Where are we?" Wen Yin looked around curiously.

"We... seem to be in a military factory!"

An Ran's face was also full of shock, very confused.

After receiving the news, the director of the military factory immediately came out to greet him and led An Ran to the office.

At the same time, Lu Yu also finished the drawings.

An Ran leaned over to look at the doubts and asked, "What is this? Engine?"

The factory director looked at and smiled, "Hehe, is this the helicopter engine drawing?"

Lu Yu laughed and gave a thumbs up: "As expected of an expert, you can tell at a glance!"

The factory director hurriedly waved his hand and said, "Master Lu is ridiculously praised. I just read too much. It's incomparable with you experts..."

Speaking of this, the factory manager pointed to the drawing again and said: "It's just that some parts on this are weird. They seem very different from our existing technology... Is it really possible to make it like this?"

Lu Yu smiled: "This is the drawing I have redesigned for the improvement of the existing engine technology. Now I see these places, I have expanded and modified the previous parts, and increased the intake system and combustion rate!"

"In addition, the interior of the engine has also been rectified, many unnecessary old parts have been removed, and new parts have been added. The overall weight of the engine is not only reduced, but also the fuel rate is greater, and the output power has naturally increased exponentially. ..."

Lu Yu talked a lot, but the factory manager heard it in the mist.

As the director of an ordnance factory, he is also a veteran expert in military manufacturing, and he has considerable research on helicopters.

This big set of theories that Lu Yu said completely violated his cognition.

It must be manufactured according to the actual situation. In some places, it will not work at all. Once such an engine is installed, the helicopter is likely to explode.

The director looked at Lu Yu and his eyes were full of suspicion. Is this guy really an expert? Is it a fake?

Lu Yu naturally felt the other party's doubts, but did not give more explanation.

If everyone can understand the knowledge of Iron Man, why not become Iron Man?

"Okay, you can be responsible for cooperating with me, the director of the factory. My people will naturally go back to deal with other things."

After a pause, Lu Yu asked again: "By the way, has the modified plane arrived?"

The director said: "I just sent it here, and now they are all parked in the yard, do you want to start?"

Lu Yu nodded: "First send the ten transport planes to the repair garage, and then remove all the engines and hoist them up, ready to transform!"

"Oh!"

The factory manager nodded in confusion, a little reluctant to leave.

If it hadn't been for the death order from the top to make him obey Lu Yu's command unconditionally, he would have rebutted it earlier.

Next, Lu Yu told An Ran to gather all the personnel, and he himself took the drawings to explain to everyone how to reform.

After several months of systematic study, Enron has imparted a lot of knowledge to the students.

Everyone was very motivated to learn, and Lu Yu was very easy to explain.

There are often many complicated and jerky theories, and he only needs to dial them lightly, and a group of students can understand and accept them.

Lu Yu continued to explain for more than three hours, focusing on the theories and knowledge points.

After the explanation, the factory director came in to report that all ten transport aircraft were towed into the repair garage, and one of the engines had been hoisted and could be modified.

Looking at the sky gradually whitening outside the window, Lu Yu said to all the students: "After listening to the theory class for so long, now I will take you to practice it yourself! Remember, don't let go of every step. The next job is You need to do it alone."

"Everyone takes out your highest level, don't hide it, the country needs you future military talents! Understand?"

"Yes!"

The students shouted loudly.

Lu Yu waved his hand and said, "Let's go!"

A group of people followed him and rushed to the repair garage.

As soon as I entered, I found that someone was disassembling an engine, and part of the engine had been completely disassembled.

Lu Yu stepped forward and pasted the drawing on the wall. Whenever a part of the engine was broken down, he followed that part.

When the engine was completely disassembled, Lu Yu immediately ordered the workers to step forward and modify it.

All the trainees gathered around to observe carefully, remembering every step in detail.

Even if it is the location of a screw, the students will carefully record it.

The director of the factory led the experts in the factory to look at them with novelty.

"The director...Is this really feasible?" an expert asked in confusion: "How do you feel like fooling around!"

"That's right, the air intake system is opened so wide, a large amount of oxygen injection will make the combustion more complete, will it not explode?"

"Two more combustion chambers have been added, and the power of the machine is greater, so it is easy to malfunction..."

Experts babbled and raised a lot of questions.

The factory director smiled bitterly: "You ask me, how do I know? Otherwise, Minister Zhang will let me reform!"

"Forget it, let's take a look at it first, whether such a modification is useful or not, I will know the result soon."

Everyone had to shut their mouths and looked attentively.

Time flickered, and it was noon in a blink of an eye.

The renovation project of the first engine is half completed.

At this time, the factory manager hurried over to report to Lu Yu: "Master Lu, according to your requirements, the recast parts and internal covering materials have all been delivered!"

Lu Yu looked up and saw that the factory director was carrying boxes of spare parts and materials behind him, and a smile immediately appeared on his face.

These materials have all been lightweighted, at least twice as light as the original.

It is more resistant to high temperatures and tougher.

Lu Yu ordered people to remove all the cylinder materials and replace them with lighter and thinner parts.

With this design, the reliability of the cylinder will be improved instantlyAssemble immediately! "

Under Lu Yu's order, all the workers became busy again.

Those who are onlookers and learners quickly record the parameters of the new materials.

When they finish the assembly alone, they can start production immediately.

Time passed by every minute, and it soon arrived in the evening.

With the efforts of hundreds of workers, this engine has finally been transformed and assembled.

"Quick! Try it now!" Lu Yu shouted.

Everyone was shocked, especially the factory director and the experts, all around.

Until now, they just wanted to see with their own eyes how this magically modified aircraft engine would perform.

Hope... it really won't blow up! ?
