"What is this?" Han Le pinched this gadget between the two, he couldn't make out the material of this thing from the touch, but it felt very light, and it still had translucent wings on its back, if it wasn't for this distance, Han Le would definitely recognize it as an ordinary flying insect, "Now the technology has developed to ...... At this point? ”

This is a flying machine about the size of a fly, and at a glance, you can see that the principle of the aircraft is a bionic design, but it lacks the head that creatures generally have, and the "limbs" are also very simple, that is, four small support frames, which seem to have no joints.

"What is this for?" Han Le asked subconsciously while putting it in his hand to study.

"Guess what?"

"Is this the smallest that can be done?" Han Le is concerned about this, "Can it be as big as an ant?" ”

"This is already the limit of what can be done at the moment," Qiao Yiyu said, "and the performance is not very stable, it can be regarded as a test product, I used it before to save you." ”

Qiao Yiyu said, picked up this little thing from Han Le's hand, and opened it for Han Le to look at his stomach: "Look, there is a small probe here, which connects the superconducting ring in the body, and the principle of action is the same as that of a stun gun." ”

Han Le sat back in front of the computer, and saw that the operation button of the combat interface was indeed "release", and when Qiao Yiyu let go of his hand, he couldn't wait to start manipulating it to fly in the room, but he was not trained after all, and he didn't know how the operation performance and flight speed of this thing were, so under his operation, this pocket fly really became a headless fly, hitting the wall everywhere in the room, fortunately, the stability of this thing was good, and it hit it several times, but the function remained normal.

"What's it called?" After ten minutes, Han Le felt that he had become a little used to this kind of operation, and to be honest, this one was easier than some of the flight simulation games he had played before.

"We call it the electric mosquito because its attack is very similar to that of mosquitoes," Qiao Yiyu said, and then pointed to a row of progress bars on the operation interface that had almost bottomed out, "This is its remaining power, fly it back, or it will be difficult to find it if it falls to the ground later."

Qiao Yiyu still said that it was late, as soon as the words fell, the picture suddenly became blank, Electric Mosquito No. 1 lost power, Han Le hurriedly went to the vicinity of the incident to look for it, and about a few minutes later, pinched this little thing and came back: "If this thing goes to the battlefield, isn't it invincible?" ”

"If the other party had known, they would have taken action against ......"

As he spoke, Han Le shifted his attention to look at the battle interface of No. 1, and found that the released button was still on, so he smiled and said, "This is really a program...... It's out of power, why don't you have to get a reminder, if you can't see the power when you command, won't it ......"

Qiao Yiyu raised her head, just in time to see Han Le controlling the pointer to move to the button that was released: "Don't move......" She just shouted, but it was already too late, and Han Le had already pressed it.

“…… The attack power is separate from the control power. Looking at Han Le, who was knocked unconscious by the electric shock, Qiao Yiyu muttered after saying this.

Fortunately, every discharge of the electric mosquito is calculated, and it will only reach the point where the target loses its combat effectiveness, so Han Le is fine, but his heart has stopped for a few seconds, and Qiao Yiyu has already recovered after a few compressions.

But it took more than ten minutes for the real consciousness to return to the original state, Han Le looked at the inconspicuous gadget on the table, and subconsciously felt stunned, and when he looked at the battle interface, the release button was still lit - but this time he didn't dare to die again, try to see if the electricity was discharged all at once.

Although he was beaten, Han Le was still interested, Qiao Yiyu seemed to anticipate Han Le's reaction, and said to him, "Don't you want to be a special soldier?" Then play this, this is the training program for special forces in the army now, have you seen this operation interface? ”

Qiao Yiyu pointed to the panel: "According to the standards I knew before, the average qualified electric mosquito operator can control seven or eight electric mosquitoes at the same time, you can try it, this game is much more testing than others." ”

"Seven or eight?" Han Le couldn't believe it, he had been a little reluctant to control it now, if he was proficient, two might be fine, but seven or eight - this was much more difficult than the two-line operation in the game!

"Who would do that?" Han Le was a little incredulous, "That must be a crazy man!" "In this era, there seems to be no mouse, and all computer operations are performed with two hands dancing into the air, which is similar to mute speech - imagine one person playing dumb speech with seven or eight people at the same time, it is not dancing with teeth and claws, it is almost like a madman.

Qiao Yiyu smiled: "When we recruited electric mosquito operators, they were selected from the top players in e-sports, have you seen the two people in the car with you that day?" They're the operators, and the game is playing well. I've seen them operate, they have changed the control settings, each finger represents an operation, the range of movement of the limbs is not very large, but very frequent, imagine a person while cleaning the glass, while playing the piano, it is similar to that feeling. ”

Qiao Yiyu's words reminded Han Le, and he thought that waving his two hands at the air can also be controlled-if he wants, he can completely simulate the mouse action against the air, and define the movement of these two fingers as left and right - this is exactly the same as using a mouse, Han Le originally thought that people in this era are not used to using a mouse, but now that he thinks about it, it is really unreasonable for the mouse not to be eliminated, and he will not have a mouse hand to operate against the air.

If what Qiao Yiyu said is true, it means that this operation method is to use all ten fingers, and the diversity of the operation is at least five times that of the mouse according to the number of fingers - this is not counting the combination of several fingers used at the same time. When you think about it, it doesn't seem so hard to imagine controlling seven or eight at the same time, as long as the brain can react.

"How does this thing charge?"

"Just put it in this box," Qiao Yiyu explained, pointing to the side of the electric mosquito box, "The green light will turn on after charging." ”

Han Le didn't wait for No. 1 to be charged, and couldn't wait to release No. 2 to try, this time he was a little bolder than just now, he directly opened the door and let it fly out of the room, and it didn't fly far, just flew around their building, but after five minutes, seeing that there was only two-thirds of the electricity left, he quickly controlled and flew back, and then he noticed a detail - if the electric mosquito flew far, the image sent back would become blurry, and it would be clear when it was closer, if it was on the box, The image was as clear as it had been taken, and from a few hundred meters away, there was almost nothing to be seen in the image that came back, only a large mass of moving color.

"It seems that the range of applications for this thing is not very wide," Han Le said, "and the distance is too close." ”

"If you can control it from a distance of thousands of kilometers, you won't be able to dominate the world." Qiao Yiyu made a joke, "But even the current level is very remarkable, it is still a national key secret project, and I am afraid that there are no more than ten people in the world who know about it." ”

……

With the new toy, Han Le's mood has changed a lot, and he spent an afternoon thinking on how to operate and play tricks, Han Le was not so imaginative at first, thinking that the electric mosquito function is at best an electric shock to put down a few people, which may be used in special operations, and subduing bandits like last time, it can really play a very limited role in a war situation - but Qiao Yiyu reminded him that the size of this electric mosquito can completely drill into the chassis of some important computers and destroy the enemy's control center, A range of several hundred meters is enough to cover an entire building. If necessary, you can even adjust the "release power" before the operation, so that one or several electric mosquitoes can assassinate important enemy personnel at the same time.

One of the most important designs of the electric mosquito is that its built-in superconducting ring will always store a part of the electricity, which will not be used, but after a period of time, about an hour or two, after the electric mosquito has not been recycled, the superconducting ring will lose its superconductivity, and within ten seconds, it will change from a superconductor to an approximate insulator, and this electricity will soon be released in the form of heat energy under the action of resistance, igniting the nearby flammable substance, thus burning itself - to Han Le's disbelief, The main material used to make this electric mosquito turned out to be carbon, which is nothing more than a three-dimensional carbon molecule that has been nanoscaled.

"Then if someone comes after us, we can use them then......"

"Don't think about it, we've done experiments in this area, and when it's really face-to-face, it's better to control this thing than to shoot twice," Qiao Yiyu said, "Especially since we are not very good at using it, at that time, the two operators also used more than three months before we dared to let them go on a mission, and at the beginning, many of them had flown too far away, and they couldn't get it back." ”

However, Qiao Yiyu's words did not hit Han Le: "It's not bad to play as a game." ”

Han Le is a very unrestrained person, this is the same as his previous extreme sports, obsessed with something that can be played repeatedly, no matter how boring, but if you are really tired of playing, it will be difficult to recover your interest in touching, the next day when Qiao Yiyu got up, he found that Han Le was still playing in the living room, his eyes were red, and he shouted excitedly when he saw Qiao Yiyu: "I will operate in two lines!" Dancing with his hands, he controlled the two electric mosquitoes to circle around Qiao Yiyu.

Qiao Yiyu instinctively dodged, after all, this was a dangerous product for her, but she didn't dodge, it seems that Han Le is really a natural gamer.

"Are you going to have breakfast?" Qiao Yiyu asked him, opening the refrigerator, "How about the next strip?" I can make hand-rolled dough. ”

"Okay," Han Le felt hungry when he said this, and he forgot to eat all night - computers in this era are not good at this, because they are operated with two hands, so they can't play while eating, "Do more." ”

When Qiao Yiyu came out of the kitchen with a big bowl of noodles, he found that the living room was quiet, and Han Le was lying on the sofa snoring, but he still woke up when he smelled it, and while eating, he began to ask: "You said that they control eight at the same time, so how can they control it?" Does one finger control the other? That won't work. ”

Qiao Yiyu really studied this problem: "It's not a finger to control one, but a set of * actions, such as collective actions, individual decomposition actions...... The whole system is standardized, even if you change the operator in the future, you can also train according to this set of * actions, which is too complicated, you can't master it in ten days and a half months, and the * action itself is also confidential, you can play it yourself. ”

"It's really a magic weapon, and it has to be specially equipped with a set of exercises...... Han Le sighed with some regret, but after thinking about it, even if he has that set of standard movements now, he may not have the patience to learn it - he followed Xie Yongqing to learn guitar before, and he just played it for two days before he left it, and now it's just for fun and a momentary interest in this thing, and the real use of this thing is militarization, and those operators themselves are professional players, so they will definitely die if they practice - Han Le himself is at best, that is, an amateur.

There is a saying about Cao Cao, Cao Cao arrived, Han Le had just been talking about the guitar, and he saw the old man carrying the piano case to their door outside, Qiao Yiyu subconsciously put away the "state secrets" on the table, and then went to open the door for the other party.

"Coming so soon?" Han Le's first sentence is.

"I came yesterday afternoon," said the old man, "and I waited for you to come and get it, but you didn't come for a day, and I was really not used to having no one to talk to, so I brought it over, just for breakfast?" ”

"I'm about to finish eating and going to bed," Han Le said, "and I played a game all night yesterday...... If no one is talking, can you always talk to the delivery person? ”

The old man was stunned for a moment, and then reacted: "How can there be delivery in this year?" When you were younger, what about the courier? The car drove over, there was no one inside, it automatically unloaded, and waited for the card to swipe and left, just like a ghost car! If you come at night, you can scare people out of sickness. ”

Han Le only then reacted, the last time he woke up in 2048, he also bought a self-driving car, and now more than 20 years have passed, this technology must have been widely used, not to mention that in this era, labor is so expensive, where may there be a need for couriers!

"People nowadays, it's just that they're too comfortable, everything is automatic," this old man is good at everything, but he hasn't finished speaking, "It's okay to cook and wash clothes automatically, and I've seen automatic feeding machines, is this a human life or a machine alive...... It's good now, just don't automatically, go to hibernation. This society can be separated from everyone, but not without machines...... You're okay, you still cook your own meals, yo, this fried noodles are authentic enough! The noodles are also hand-pulled? ”

Qiao Yiyu nodded: "Yes, one by one, the noodles sent last night, do the hand-rolled noodles have to be so delicious." ”

"Listen, listen," the old man seemed to have found a soulmate, and praised Qiao Yiyu repeatedly, "In this era, women like you are dying!" I tell you, my son got married for the first time, I went to their house for dinner, their kitchen is all automated, make me sauce elbows, I told them to put less salt, the machine is too salty - they give me a sentence is set, I don't know how to do it, and they say that this taste is the most authentic sauce elbow. ”

Han Le glanced at each other with Qiao Yiyu a little embarrassed, and didn't know if he should take this conversation, but the old man didn't seem to need anyone else to talk to him at all, so he said to himself: "At that time, I said that they couldn't grow up, and sure enough, I just had a child, and the two of them are going to divorce, and the children don't care, they will throw them to others...... This expert is no god, and he is not a parent...... The result? The son has been raised and has a good life, but even if he lives or dies, he doesn't recognize them as his parents! You don't leave any of the money you earn, and you say, "Isn't this iniquity!" ”

"Uncle, did you forget to ask before? What do you call it? Han Le took advantage of this gap to interject.

"The surname is Zhang, and the bow is Changzhang." The old man said, but did not ask them rhetorically, but had a tendency to continue the topic just now.

"That's right, Uncle Zhang," Han Le said politely, "I didn't sleep well last night, I still have to go to sleep, you guys talk slowly, talk slowly......"

This was originally a kind word, and after ordinary people heard it, they got acquainted and left, but Zhang Da Dick didn't, after Han Le went back to his room, he began to spit bitterness at Qiao Yiyu wholeheartedly, Han Le covered the room with a quilt, but his voice still couldn't stop drilling into his head - the key is that Uncle Zhang's words carry too much information, Han Le basically can't help but analyze a sentence after listening to it, probably speculating about what happened in the past, which is more tiring than listening to him in person.

Uncle Zhang's words are some parents in the short, the son is not angry but still filial, a little humane, the grandson is angry, but like a stranger, when he is almost 30 years old, he threw a bank card to him, hibernating, after a few years, the son was found to have diabetes, go to help them do a check-up before going to the second elder, a check, the wife stomach cancer, the operation is afraid that it will not survive, and I also went, others persuaded Uncle Zhang to go to hibernate with his wife, and when she woke up, she could be accompanied, but Uncle Zhang stubbornly refused - in his opinion, people should live naturally, What's the matter if you're sick and healed, when you're dead, you're buried, and you're all frozen there?

Then Uncle Zhang talked about the stricter restrictions on hibernation that the government is going to enforce this time, and if it really comes according to the law, his son and grandson will have to go home immediately, but Uncle Zhang said that it doesn't matter if they come back or not - they haven't seen each other for more than ten years, they are like strangers, and they can't say a few words when they meet.

Uncle Zhang's chat was a morning, and Han Le didn't know when he fell asleep, nor did he know when he would leave. He was woken up by the sound of the guitar, but he was not disgusted - on the contrary, this sound made him have a wonderful dream before he woke up, in which he sat in the old seat of the November bar, watching Qiao Yiyu on the stage play the piano, and in the dream, he could even see Qiao Yiyu's focused smile at him - that kind of real affectionate look is something that Qiao Yiyu will never appear in reality.
