When you are rich, there is Rheinmetall; when you are poor, there is Rheinsteel!

The two students on the ground had finished checking the drone, put away the equipment, turned around and found that their teacher was still hanging around there, still doing chest expansion exercises.

"Teacher." The student on the right shouted, and the sound startled Huang Tianhai.

He slowly turned around, looked at the drone and students next to him, and asked: "Have you finished checking?"

The two students nodded repeatedly, indicating that the preparations had been completed and now they needed to test fly.

Huang Tianhai, who was worried, went forward to check it himself again. After the inspection, he did not fly, but walked to a cardboard box next to him, reached out and grabbed a big rooster from the cardboard box, and then took out a kitchen knife from the cardboard box.

Ignoring the screams of the big rooster, he carried the rooster to the drone, and with a light stroke of the kitchen knife, he cut the rooster's throat.

The bright red chicken blood spilled, and Huang Tianhai evenly sprinkled the chicken blood on the wings of the drone.

When the last drop of chicken blood fell, he threw the chicken and the kitchen knife back into the cardboard box together.

After doing all this, he picked up the remote control handle on the table next to him, took a deep breath, and pressed the power button in the center of the remote control handle.

The electronic signal was sent out from the handle and fell on the signal receiver of the drone. The signal receiver transmitted the signal to the control motherboard and the power was turned on.

The light came on, the equipment self-test light flashed, and turned green after a while.

As the green light came on, Huang Tianhai pressed the start button.

Beep!

A crisp sound rang out, and the four rotors of the drone began to rotate, making a buzzing sound at the same time, just like the mosquitoes that had been flying around my ears on a hot summer night in June and July.

Seeing this, Huang Tianhai stepped back a few steps and retreated to a safe position. His right hand gently turned the knob on the remote control to provide the motor with higher power output, and as he moved, the wing rotated faster and faster!

Soon a lift was generated under the wing, pushing the drone to slowly climb. While the drone was climbing, Huang Tianhai gently adjusted the melody and controlled the rotation speed to keep the drone in front of him.

"Load test begins!"

Listening to his command, two students squatted and quickly came to the bottom of the drone, stretched out their hands to grab the traction hook under the drone, and hung the prepared cement blocks on it.

The traction rope slowly straightened, and the drone slowly climbed up with three cement blocks, and then hovered in front of everyone.

Then, waving to the people in the distance, Huang Tianhai controlled the drone to move forward, backward, left and right.

Under his control, the drone moved to the tunnel entrance next to it. In full view of the crowd, he pressed the switch on the remote control handle, the drone received the signal, the hook below was released, and the three cement blocks on the traction rope fell accurately into the tunnel entrance in full view of the crowd.

The action was not flexible, but it was small.

After repeating this several times, Huang Tianhai handed the remote control to the students and turned to walk to the viewing platform of the weapons test site.

He walked into the viewing platform and saw Lin Yu and two strange Arabs standing at the window. He walked over and asked with a smile: "How do you feel?"

"I know you are shocked, but don't be shocked. Give me more time and more research funds, and I can do better."

As soon as he finished speaking, he saw Lin Yu standing by the window sill waving his right hand, and then said: "Old Shao, go over and test it."

"Take the remaining drones with you, and these mobile phones."

Shao Xiaofeng, who had been standing next to him, didn't say anything, but silently took the prototypes on the table in his hand, walked out of the viewing platform, and waved his hand, and immediately two people pushed out several boxes from the house next door.

The box was painted green, with only a few simple markings, 120mm mortar shells.

CL20.

There were also a bunch of plastic parts on the box, and those plastic parts exuded a cheap feeling all over.

After putting the phone on the box, Shao Xiaofeng turned around and moved the box containing the drone onto the flatbed truck. The three of them creaked and walked towards the center of the weapons test site.

Watching the backs of the people leaving, Huang Tianhai had an ominous premonition in his heart. He slowly turned around and looked at Lin Yu who was still standing in front of the window next to him, and asked carefully:

"You don't want to put these bombs on the drones and blow them up directly?"

At this time, Lin Yu finally turned around and looked at Huang Tianhai, smiling and said: "Professor Huang, you are so smart!"

"You actually guessed my intention!"

Hearing that he was going to blow up all the drones, Huang Tianhai was dumbfounded. He hurried to Lin Yu, not caring about the two foreigners next to him, and said loudly:

"But this This thing is a prototype. The cost of this crude and rotten product alone is as high as 500,000 yuan! "

"What's more, my data has not been collected yet. If you blow it up, our R\u0026D cycle will have to add at least two more months."

Huang Tianhai's words made Lin Yu silent. After a long time, he raised his head, looked at Huang Tianhai and asked: "Professor Huang, do you know how much it costs to train a qualified soldier?"

Lin Yu's sudden question made everyone else turn their heads, because Lin Yu had been promoting this drone, and even went to Shenzhen City for this.

Now, he is finally going to reveal the answer to this mystery. If you don't listen now, when will you listen?

However, in the expectation of everyone, Lin Yu slowly opened his mouth and explained:

"An ordinary infantryman, if according to American standards, costs about $200,000 from recruit to battlefield, and the equipment he wears is worth about $50,000."

"An armored soldier costs about double that of an infantryman."

"A Hummer armored vehicle costs about $1 million, and an Abrams tank costs about $6 million."

"And our drones target tanks, armored vehicles, and ordinary infantry."

"The manufacturing cost is 500,000, plus two mortar shells, $200. As long as it is operated properly, it can easily eliminate a squad of infantry and the armored vehicles carrying these infantry."

"If additional explosives are added, an Abrams tank can be easily eliminated."

"Calculate this cost, what do you think?"

Listening to the data that Lin Yu broke out one after another, Huang Tianhai's brain turned quickly, and began to calculate the price using the exchange rate in his memory. Soon he came up with a sky-high price.

Then, the professor licked his lips very unconvincingly and asked blankly: "Are those broken things so expensive?"

"Yes, they are so expensive!" Lin Yu nodded slightly, then folded his hands in front of his chest, turned around and looked out the window. After a few seconds, his faint words rang again:

"In fact, making this thing is like Tian Ji's horse racing."

"America's real tank is a top-grade horse, and this drone is the top-grade horse here, but the cost of the two is very different. You only need one drone to exchange for one of the other's top-grade horses."

"Professor Huang, if it were you, what would you think of this deal?"

The metaphor of Tian Ji's horse racing made Huang Tianhai quickly understand that the manufacturing cost of a tank is expensive, and the manufacturing time is also expensive.

And a drone, no matter how expensive it is, is not more expensive than a tank.

What's more, there are several armored soldiers on the tank, and these people also have a price.

After figuring this out, Huang Tianhai's face was filled with excitement again. He also stood at the window, picked up the telescope on the windowsill and looked into the distance, looking at the people assembling drones.

After watching for a while, he responded with a smile:

"Of course it's a big profit!"

While they were chatting, the people led by Shao Xiaofeng also assembled the drones at the weapons test site in the distance.

After checking that nothing was left out, several people retreated to the bunker together.

Shao Xiaofeng picked up the intercom and pressed the switch: "The drone is ready, do you want to start the test?"

Ding——

"Test start!"

Under the guidance of Shao Xiaofeng, Huang Tianhai's two students each controlled a drone to slowly take off, and then one of them, under the guidance, crashed into the tractor simulating a tank in the distance.

With a loud bang, the tractor's fuel tank exploded, and a mushroom cloud rose directly.

This scene was seen by Rhodes. The Iraqi who came from afar seemed extremely excited at this moment.

With this thing, they don't have to get close to the Americans, they can control it from a distance and launch a sneak attack!

When the smoke and dust cleared, the second drone set off. Under this drone, there were 8 120mm mortar shells, and its usage was different from the first one.

Under the gaze of everyone, this drone slowly flew to the ruins next to it. After a short stay above the ruins, this drone began to drop bombs.

The body tilted slightly, the mechanical switch below was turned on, and 8 120mm mortar shells fell into the ruins like dumplings.

What followed was a deafening explosion, one after another. After eight explosions in a row, the ruins that were originally ruins completely turned into flat ground.

Seeing this scene, Rhodes was even happier.

This is simply equipment tailor-made for them and born for them.

At this time, two more drones set off. They did not tie mortar shells, but hoisted a box.

The small box was very inconspicuous hanging under the drone.

Under the control of the two students, the two drones flew to the place where the tractor exploded just now, and then hovered above the tractor.

No explosion occurred.

Just when everyone was surprised, Lin Yu took out a very simple-looking mobile phone from his pocket, handed it to Rhodes, and then said with a smile:

"All guests who come to our factory can experience our equipment in person. At the beginning, Jialim experienced those shells. Now, it's your turn."

The mobile phone that was picked up came into Rhodes' hands as he spoke. Looking at the Arabic displayed on it, he was confused.

He couldn't figure out what the equipment had to do with the mobile phone.

At this moment, Lin Yu stretched out his finger and touched the dial button. After being pointed like this, Rhodes also saw the content displayed on the mobile phone screen clearly.

It was a mobile phone number.

Subconsciously, Rhodes stretched out his hand and pressed the dial button and dialed the number.

No response.

Just as he was puzzled, a shocking explosion was heard at the weapons test site in the distance!
