Crossing through time 04, I blew up the American aircraft carrier.

Europe in mid-March is neither too hot nor too cold.

Standing on the grounds of Berlin, Qin Yuan had mixed feelings. After struggling in the middle of nowhere for a month or so, he had finally arrived in the modern civilized world!

The Spree River flows quietly, the Brandenburg Gate is bathed in the morning light, and the green-domed Berlin Cathedral can be seen in the distance...

The streets are bustling with people.

At this moment, Qin Yuan, dressed in a suit and tie, seemed to have already integrated into this modern world.

Beside him, Said shifted his neck somewhat uncomfortably, the tie making him uncomfortable.

For someone who has never set foot in the Western world, modern civilization is something he cannot adapt to.

His worldview was greatly shaken, especially by the women who dressed provocatively.

"Hassan, I..."

"Sayyid, remember, we are now international merchants from Lebanon, and you are my bodyguard. Come on, let's do something very important!"

"Uh-huh."

Before setting off, Said's mission was to protect Qin Yuan on his journey to Li Tuo, to find the guests who had previously visited the tribe to ask them some questions, and to purchase suitable equipment if he came across any.

Little did he expect that Qin Yuan would find a local smuggler in Lituo, obtain a genuine Lituo passport, buy a plane ticket, and fly directly to Europe!

Said didn't know what Qin Yuan was going to do, but... he knew that the chief had asked him to protect the young chief, so he had to listen to the young chief.

Qin Yuan was very satisfied. Said was his best friend since childhood, and he was absolutely loyal and reliable!

He'll do whatever you ask him to do; he's not very bright, so he won't cause any trouble!

Berlin Technical University of Applied Sciences, Department of Electronics and Precision Engineering.

dong dong!

A knock came at the door.

A student with bloodshot eyes opened the door and looked at the people outside: "Who are you?"

"We're from David Aerospace Industries. My name is Schwartz. Is Dr. Booth in?"

Dr. H. Booth emerged, sporting dark circles under his eyes: "What do you want?"

"Yes, Dr. Booth, we've heard that you and your team are developing an autopilot for quadcopters, and we'd like to purchase all the technology patents."

Upon hearing his words, Dr. Booth immediately shook his head: "No, our research results must be open source!"

"Dr. Booth, if I may be so bold, quadcopters are incredibly powerful and will be a world-changing product. We at David hope to keep this technology in our own hands to ensure world peace. If it falls into the hands of terrorists..."

"I'm sorry, but I don't want to hear your arguments. If you're here just to stop our project, then please leave!"

Schwartz's face also darkened: "Dr. Booth, are you rejecting us? Rejecting David's kindness will not end well."

"roll!"

Boom!

The door slammed shut, nearly hitting Schwarz's high nose bridge, and his face visibly darkened.

Hmph, do you really think we Davidians have no other means?

"Mr. Schwarz, are you alright?" His assistant came up, looking very worried.

"It's alright, let's go find their director!"

"it is good."

After the two left, two people came out of the toilet next door.

"Hassan, we..."

"We've seized a good opportunity, now..."

Saeed's eyes widened: "No, this is too dangerous!"

"Sayy, do you know what's most important in this world?"

"What?"

"Talented!"

Even in the 21st century, Yemen remains poor and backward, with an illiteracy rate exceeding 60% and an infant mortality rate exceeding 60%. The cities are somewhat better, but in the mountainous areas... there are hardly any talented people!

Despite traveling through the mountains, Saddam Hussein and the Houthis did not spread modern science and technology.

If the Houthi rebels are to be brought onto a path of formalization, they need professional personnel!

Let's start with Dr. Booth!

I originally only planned to buy a batch of quadcopter drones from Dr. Booth, but I didn't expect... I'll have an even bigger surprise!

As a special forces soldier, Qin Yuan was already used to using drones. After being transported to Yemen, he was forced to fight one primitive battle after another. Now, he is finally going to upgrade his equipment!

Back when airplanes first appeared, there were all sorts of layout options. The Breguet brothers in France tested rotary-wing helicopters, and by the 1920s, they had developed multi-rotor helicopters.

However, due to the backward control technology at the time, this solution had many flaws and had to be abandoned in the end.

This period of silence lasted until the 1990s.

With sophisticated micro-motor systems in place, and MEMS inertial navigation systems weighing only a few grams, the foundation for multi-rotor aircraft is finally complete!

However, these aircraft did not enter the military field; they were initially just remote-controlled toys!

In 2002, at a competition for young researchers in Germany, the quadcopter codenamed SilveritX-UFO from the Technical University of Berlin made its debut and amazed the audience!

The only drawback is that it still requires remote control and lacks an automatic control system!

So, after the competition, Dr. Booth and his team continued to study the autopilot needed for the quadcopter, codenamed Mikrokopter!

This guy is amazing. He hopes that quadcopters can fly all over the world, so he is willing to release his research results, which means open source!

Open source is not just about releasing the source code. Control algorithms and simulation environments are all released, and on the hardware side, motor drivers, central control boards, firmware, and so on are all made public!

In later generations, the quadcopter drone flight control technology that became popular all over the world all started from his Mikrokopter technology!

This is similar to how most quadruped robots in the world originated from MIT's Mini Cheetah project.

Open source is great! Qin Yuan loves open source!

If this guy hadn't open-sourced it, would we in the East have such a large number of quadcopter drones? High-end DJI, low-end... 9.9 yuan with free shipping on Taobao...

Yemen lacks modern industry, so the Houthis have to source cheap raw materials for their weapons from the East! The East's greatest strength is its ability to make all high-end industrial goods incredibly cheap…

It's a pity this was only in 04. If it were 14... why bother with Germans? Just register a Taobao account and place an order! We should give it a push ourselves!

David noticed the dangers this thing could cause, so... he wanted to come and buy it, but little did he expect that Dr. Booth wouldn't buy it at all!

In Berlin, the three most representative top universities are the Free University of Berlin, Humboldt University of Berlin, and the Technical University of Berlin. However, anyone with a little knowledge of Germany knows that it has a famous spirit of craftsmanship, and its technical schools are just as popular as its universities.

The Berlin Technical University of Applied Sciences is the most famous technical school in Berlin. The students here are all... those who were streamed out after the fourth grade of primary school.

Some of those who went to vocational schools were not content with their current situation; they also wanted to do scientific research!

Dr. Booth's team is just such a group of people; they want to tell all Germans that vocational school students are also very capable!

In fact, they did it. A few years later, their technical school was transformed into a comprehensive university. Their project played a significant role in promoting this transformation!

As for now...

Dr. Booth, come into the Houthis' bowl!
