The female classmates are the same

Drones.

Jiang Yan still remembers that drones first shone brightly in the public eye when they were used in war.

Whether on the Russia-Ukraine battlefield or in the Middle East, these constantly humming war machines are like Death whistling leisurely, precisely reaping lives one by one.

Soldiers in World War II hid in trenches, fearing the shrieking of Stuka bombers. In modern warfare, soldiers still hide in trenches, but what they face is even more terrifying.

In the midst of a zombie apocalypse, drones are undoubtedly the most powerful helpers.

Zombies have no ability to attack aerial targets.

Anyone who has played games knows how important location information is. Drones can plan their routes before each operation, avoiding hordes of zombies and greatly increasing the chances of survival.

In addition, drones have a large number of DIY accessories, making them more versatile than one might imagine.

Jiang Yan hadn't studied it much, but Su Muyun was definitely an expert, not to mention that her family owned a drone factory.

This will save you a lot of trouble.

"Very good. Drones are very important. You can focus on preparing for this during this period. Just focus on these four aspects: reconnaissance, transportation, communication, and combat."

Jiang Yan briefly explained that the savior seemed intelligent and should know what to do.

If all else fails, conduct a thorough investigation into her situation in a couple of days to see how well she's prepared.

"Yes, investigating transportation and communications isn't too difficult. My dad's company has specialized samples," Su Muyun said immediately, eager to make her contribution.

Since this man claims she is a savior, she cannot simply be an appendage.

The end of the world is the end of everyone.

"Yes, it would be best to do some special noise control, since zombies usually follow sounds."

If you want to use drones to create noise to lure away zombies, just make a special broadcast drone. In other situations, it's best to use a silent model; silent reconnaissance is always a good idea.

"Okay, I'll go back and have the factory order a batch of parts." Several options instantly popped into Su Muyun's mind.

She spoke fluently and confidently: "For example, bionic wings, or simply putting the propeller into a cylindrical duct, can make the airflow smooth. By laying a layer of sound-absorbing cotton inside the duct, the aerodynamic noise can be reduced to a minimum."

"With a low-speed, high-torque motor and proper vibration reduction, the mechanical noise will be very low. These are not difficult to achieve."

Su Muyun rode her bicycle ahead, saying, "However, these things will increase energy consumption, and the drone's battery life will be very short."

"It's alright. There won't be a shortage of energy in the early stages of the apocalypse. Once things stabilize, I'll find a place to lay solar panels. Rebuilding the power grid shouldn't be a problem."

Jiang Yan had some electrical engineering skills and usually solved problems on his own.

Since he hasn't been electrocuted yet, it means he's learned quite well.

Su Muyun said, "Well, the other functions are fine, but as for attack drones... our drones have mounting hardware, but we can't build the things that can be mounted on them."

"Mountway?"

The term sounded somewhat unfamiliar to Jiang Yan, so he asked, "How many things can it hang on?"

"50 kilograms," Su Muyun replied. The business related to drones was one she recommended her father to pursue.

After that dream with odds of 6500, this is her second rare precognitive dream—a drone.

Investing in drones can make you a lot of money.

Therefore, she herself is quite attentive and has a thorough understanding of some core data.

"It has a range of about 1500 kilometers and uses both inertial and satellite navigation."

Jiang Yan grew increasingly puzzled as he listened, and then tentatively asked, "The kind of drone you're talking about... usually doesn't return to base?"

"Of course." Su Muyun nodded. "Didn't you say you wanted attack drones? Our factory has been manufacturing them recently to supply the Middle East."

Jiang Yan: "..."

I understand, she was referring to the aerial motorcycle—a suicide drone.

I never knew her dad made this; this thing really shines on the battlefield.

"This thing... we probably won't need it, unless you're planning a northern expedition." Jiang Yan shook his head, but he was also curious, "What's the cost? How much do you sell it for?"

Without hesitation, Su Muyun revealed the company's top secret: "The cost is over ten thousand, but the selling price is only thirty-eight thousand."

Jiang Yan did some mental calculations and sighed silently.

That's why they say war can make you rich.

These things cost tens of thousands of US dollars to make in the Middle East, and even more than seventy or eighty thousand US dollars a unit when made in the United States. And you still have to share them with Commissioner Smith. How can they compare to the cost-effectiveness of drones from an unknown small factory in a third-tier city in mainland China?

She whispered, "The drones we sell don't have labels, so we can bargain and get them even cheaper."

"Of course we won't put up any signs. Aren't these things all dug up by the Persians from the desert?"

Jiang Yan made a casual remark, but he actually started making plans in his mind.

This thing is quite powerful even with a gas cylinder attached; it's perfect for clearing out large numbers of zombies.

It's a pity he didn't know how to mix explosives, otherwise the fastest and safest way to clear out zombies would definitely be to make his own explosives.

However, this thing doesn't seem difficult; anyone with expertise in chemistry could make it.

As for Jiang Yan himself, if he strictly follows the recipe, he should be able to make it himself.

However, he was well aware that the control over the relevant materials was quite strict, and it was best not to act recklessly before the end of the world.

There are many things about him that can't withstand close scrutiny. They might be okay individually, but if you look at them all together, it will cause a lot of trouble.

It included raw materials for explosives, diesel fuel, composite bows, arrowheads, and other such items...

Young man, tell your uncle what you're planning to do?

"Besides these, I also researched AI for a while. I originally wanted my dad to invest in it with me, but I couldn't find a way to do it, so I gave up."

"If you could provide me with a large amount of data on the appearance of zombies after the apocalypse, I should be able to train a model that can distinguish between zombies and humans. This model could be mounted on a drone system, making it much easier to plan routes and rescue survivors."

Su Muyun then mentioned another skill she possessed.

"That would be great."

Jiang Yan was increasingly satisfied with his savior. Just by looking at her appearance, he really couldn't tell that Su Muyun belonged to the "tech geek" category.

Although it seems that it all came down to getting her father to invest, these industries look promising now, but ten years ago, few people thought that domestic industry could get involved in these things.

"Oh, right."

Su Muyun parked her bicycle by the roadside and asked a question she had been thinking about for a long time.

"What about my parents? And what about some of my classmates...?"

Jiang Yan also stopped his car. He had thought about this question, and his answer was very realistic.

"I can go and rescue them, but I won't take them with me from the start."

The rescue was to organize the survivors to restart the city.

Gathering such a group of people before the end of the world is too risky; he has no confidence in controlling the situation.

Come to think of it, saving a group of high school students first wouldn't be a bad idea.

A group of naive students who have gone through nine years of compulsory education may be much more useful than adults.

Su Muyun lowered her eyes slightly, knowing that she had no right to ask others to take risks to save lives.

However, she quickly rallied: "I will try my best to keep them indoors that day and stockpile supplies to await rescue."

"Okay." Jiang Yan fully agreed.

"The apocalypse happens on a weekend, so I can stock up on enough food and water at home beforehand, and then call all my classmates over. That should be enough."

Su Muyun quickly came up with a solution.

"They'll all come?" Jiang Yan was surprised by her popularity; he himself was basically invisible during high school.

She thought for a moment and said, "I can say that I'm going to confess my feelings to him and that I'm throwing a super cool party at home. He'll definitely come."

Jiang Yan looked at her again, finding her believable, but still had a question: "What about the female classmate?"

Su Muyun affirmed, "The same goes for female classmates."

Jiang Yan: "..."
