Love Guide for Childhood Sweethearts

"So you really think it's a toy for children?" Lin Jingzhe looked at him with a mixture of laughter and tears, "It's like a remote-controlled car."

"What else? What can this drone do?" Lin Xingzhi said, looking at him with his black and white eyes.

"Haven't you thought of any other uses for it?" Lin Jingzhe stared at him with his light brown eyes.

"Other uses?" Lin Xingzhi said to her with a frown.

"Agricultural, civilian, and military use. Didn't you just say that the Americans use it for military use? It's not just a toy for children." Lin Jingzhe looked at him with his glassy eyes and said.

"Agricultural use? Farming?" Lin Xingzhi frowned and looked at her. "How can this be used?"

"Sister, this can't be used to farm!" Lin Qiwei blinked as she held the drone in her hand. Farming with this little gadget? "This doesn't make sense! It doesn't make sense!"

"How do you spray pesticides?" Lin Jingzhe looked at them with eyes as gentle as jade.

"A watering can!" Lin Qiwei stood up and patted herself on the back. "It's so heavy to carry the watering can. I have to dig into the ground in the middle of summer."

"Can't we let it carry the weight underneath and spray pesticides like an airplane?" Lin Jingzhe said, looking at her with a smile in his peach blossom eyes.

"That's fantastic," Lin Qiwei said excitedly, "but it's only the size of a palm. Can it bear any weight?"

"Your brother will answer you for that." Lin Jingzhe's eyes fell on Lin Xingzhi and said, looking at his dull eyes, "Brother, what are you thinking about?" He waved his hands in front of his eyes, "Brother!"

"Oh oh..." Lin Xingzhi came back to his senses and looked at her and said, "Where were you talking about?"

"This drone can be used for spraying pesticides and picking fruits. There are many mountains in the south, so with it, we don't have to run up and down." Lin Jingzhe said with a chuckle, "It's more convenient than the cable car."

"How much horsepower does this require! The cost will still go up." Lin Xingzhi said to her with a frown.

"That's what you need to research: how to reduce costs and increase the load capacity." Lin Jingzhe looked at them with innocent eyes and said, "If it can carry pesticides, it can also carry bombs. You can also install radar, thermal imaging, and cameras, and connect it to a computer, just like a surveillance camera."

"Cough cough..." Lin Xingzhi was so frightened that he kept coughing.

"Why are you so surprised?" Lin Jingzhe looked at him innocently with his clear peach blossom eyes and said, "Look at the American aircraft carrier. Once the door opens, so many warships fly out." He looked at him with a smile and said, "Turning science fiction into reality!"

"That's a warship." Lin Xingzhi kindly reminded her.

"So what? It's your drone battleship!" Lin Jingzhe said simply and easily.

"Brother, whatever car bombs they have, our drone bombs will do. The tanks are just sitting ducks." Lin Qiwei said, looking at him with sparkling eyes.

"That's absolutely right! This also means air supremacy." Lin Jingzhe's eyes lit up when he heard that.

"You two?" Lin Xingzhi looked at the two excited people helplessly.

"What's wrong with us? Did we say something wrong?" Lin Jingzhe looked at him innocently and said.

"What can one or two of these planes do?" Lin Xingzhi looked at them with amusement, always feeling that he was unreliable in this matter.

"They're like a swarm of locusts, overwhelming even the American aircraft carriers. When they're poor, they use tactical interspersal tactics; when they're rich, they use firepower coverage. Two fists can't beat four hands. Costs are cut, so we won't feel bad if our drones are destroyed." Lin Jingzhe said proudly, his chin slightly raised. He pointed at the drone in Weiwei's hand with his index finger and said, "Is this that difficult? The fuselage is just a mold! With the batteries and motors, the load isn't too much; it's the weight of a grown man." He looked at him calmly and said, "Our soldiers don't have to risk their lives anymore."

Upon hearing this, Lin Xingzhi froze in place as if struck by lightning.

"Brother...Brother..." Lin Jingzhe looked at him who looked like a statue. "Is it so hard to understand?"

Lin Xingzhi stood up and said, "I'll go to your bedroom to make a phone call." He looked at her with bright eyes.

"Wait a minute, wait a minute, don't be in a hurry, finish what you want to say." Lin Jingzhe looked at him with his glassy blue eyes.

"What?" Lin Xingzhi sat down again and looked at her with burning eyes.

"Why are the costs so high for the Americans? They even stopped researching halfway through." Lin Jingzhe looked at him with eyes as gentle as jade.

"Of course the capitalists don't want this. The cost is high and the profit is low. It's not without profit that they get up early." Lin Xingzhi said without thinking.

"What about the top brass? The strategic brass, can't they see its value?" Lin Jingzhe pressed on. "I don't believe the military is blind."

"Even the strategic leaders can't beat the capitalists!" Lin Xingzhi lamented, adding, "The military can only paint a picture. Making money is too slow. It's not as good as fighter jets, which cost tens of millions of dollars each."

"This isn't a technical error, but a philosophical one." Lin Jingzhe looked at them with his dark eyes and said, "Since I know about drones, I guess I also know about robot dogs!"

"I know! The Americans started researching robot dogs in the 1990s, but the cost was too high, so they even released the source code." Lin Xingzhi chuckled, "Some people in our country are researching it." He then said, "The American robot dogs use hydraulics, but the effect isn't very good, and the price is very high." He smiled and said, "We use electric power."

"The Americans' electricity is not good." Lin Jingzhe snorted, his tone full of contempt.

"How is that possible?" Lin Qiwei looked at her in disbelief and said, "That's an American."

"It's true. Their telephone poles are still made of wood." Lin Xingzhi looked at her with deep eyes and said, "It's still one of the biggest cities."

"The electric poles in my house are all made of cement." Lin Qiwei said as she looked at them with her eyes wide open.

"I'm not lying." Lin Xingzhi looked at her with sincere eyes and said, "Look at their population distribution. Aside from a few large cities that look like developed countries, the other villages and towns are worse off than us! The land is vast and the population is sparse. Capitalists won't take care of every aspect of the people."

"Our west-to-east electricity transmission system uses ultra-high voltage to ensure that electricity reaches thousands of households." Lin Jingzhe said as he looked at them with his peach blossom eyes curved.

"It seems that my home rarely has power outages since the year 2000." Lin Qiwei said after thinking seriously.

Lin Jingzhe looked at them with his deep black eyes, a glint flashing in his eyes as he said, "The Americans don't consider low prices and high volume when producing products. Instead, they are moving towards high prices and high technical barriers."

"They were the ones who proposed that technology should be people-oriented. Now, they often create technical barriers, which has lost its original intention," Lin Xingzhi said with deep emotion. "Technology should serve people."
