Hand over the jade seal first [Infrastructure]

Xiao Xuexing was slightly taken aback: "Solved?"

When he saw the drawing, he thought it was Xiao Zirong's concept, well, the word concept came from Xiao Zirong's mouth.

Didn't expect it to come out so quietly?

Xiao Zirong said: "I know Yuan Ke's mental illness very well, of course we should take precautions early."

"Huh?" Xiao Xuexing squinted at him: "You know him well?"

Xiao Zirong hugged his neck with a smile: "Don't be jealous, you know what I mean."

Xiao Xue put down the blueprint, hugged Xiao Zirong with one hand, and dishonestly with the other hand, asked casually: "Then how did you solve it?"

Xiao Zirong subconsciously straightened his back, his thoughts were disrupted for a moment, he swallowed and pushed Xiao Xuexing and said, "Don't make trouble, let's get down to business."

Xiao Xuexing looked up at him: "Don't you like it?"

Xiao Zirong: ...

That's still something I like.

Xiao Xuexing continued: "Your Majesty says what His Majesty does, and I do what I do."

Xiao Zirong lay down on him and bit Xiao Xuexing, trying to maintain clarity and said: "The height of the flying kite depends on the wind direction and the take-off altitude. The take-off altitude can be selected from nearby mountain peaks or, um... the ladder is not impossible, slow... …Slower……"

Xiao Xuexing said, "What about the gunpowder bamboo tube?"

Xiao Zirong's heartbeat accelerated, and he hugged him tightly and said, "Changed... changed the trigger method so that it will only explode when it is shaken violently, and... added... a little something."

When he talked about the latter, he couldn't concentrate. If it wasn't for the flying kite and the gunpowder bamboo tube that he found various materials and finally "designed" and handed them over to Taoyuan City for experimentation, he probably wouldn't know what he was doing. What did you say.

Xiao Xuexing didn't ask any more questions.

At this time, Xiao Zirong raised his head high, showing his Adam's apple, which attracted Xiao Xuexing to lean over and love him a lot.

After a while, Xiao Zirong relaxed his tense body, and leaned limply on Xiao Xuexing's body, watching him slowly wipe the dirt off his fingertips.

The rays of the setting sun penetrated in and shone on Xiao Xuexing's body, the hands against which were full of lust.

Xiao Zirong's face flushed, and she leaned into Xiao Xuexing's ear and complained: "You are clearly talking about business, but you want to mess around."

Xiao Xuexing glanced at the drawing and said, "Didn't you solve it? Besides, I have to feed you before I leave."

Xiao Zirong was surprised after hearing this: "Where are you going?"

Xiao Xuexing said: "According to the current progress, it will be a matter of time before we reach Luoyang. If Feiyuan really comes in handy, I'm afraid we will be able to reach Luoyang in less than two months."

There was nothing wrong with Xiao Zirong's calculations. Originally, they occupied a part of Yuzhou city, which was very close to Luoyang.

This time the Northern Wei Dynasty called and took away that part of the city, so they sent troops from that side at that time, Xiao Xuexing's judgment was not wrong.

He was a little confused and asked, "Then what are you going to do?"

Xiao Xuexing kissed him and said, "I'll go and catch Yuan Ke back myself."

Xiao Zirong's eyes widened, and Xiao Xuexing helped him straighten his somewhat disheveled hair and said, "I promised you back then that I would definitely bring Yuan Ke back to let you vent your anger."

It's just that at that time he thought that Xiao Zirong would not be the emperor, so it was not easy to achieve this point, but he didn't expect a turnaround.

Now that Xiao Zirong ordered someone to capture Yuan Ke, Ling Fu and the others were all eager to try. Capturing the enemy emperor was a great feat, and it would be recorded in history books.

Xiao Xuexing doesn't care about meritorious deeds or being famous in history, but he wants to fulfill his original promise.

Xiao Zirong hugged his neck and said, "If you don't go, don't go, what are you doing all the way there? Yuan Ke is also worthy of you to do it yourself?"

Xiao Xuexing picked him up and walked out, Xiao Zirong was taken aback: "What are you doing? Let go?"

Fortunately, Xiao Xuexing didn't really carry him out of the study, and put him down at the door, then took his hand and said, "But I want to go."

Xiao Zirong looked at Xiao Xuexing seriously for a long while, then sighed: "Well, you don't care about my sleeplessness, go ahead and go."

Xiao Xuexing laughed, the two of them don't sleep together every day, sometimes Xiao Xuexing needs to deal with things and has to leave.

He leaned into Xiao Zirong's ear and said, "Why don't I leave something for you?"

Xiao Zirong turned her face away: "You should go out of the palace."

Xiao Xuexing laughed, and finally followed Xiao Zirong to the bathing hall.

Although Xiao Xuexing said that he would go to Luoyang to capture Yuan Ke back in person, in fact, he would not go there immediately.

Feiyuan still needs to be tested.

Fei Yuan's conditions were too harsh, if Yuan Ke hadn't suddenly gone crazy and called, to be honest, he didn't really want to take it out.

"You've been made and you don't want to take it out?" Xiao Xuexing stood beside Xiao Zirong and looked at the flying kites flying into the sky, even he couldn't help yearning for it.

Flying is probably the eternal pursuit of human beings, and even the most rational people can't help being excited when they see that they can fly into the sky.

Xiao Zirong looked up at Fei Yuan and said, "This thing was originally intended for us to play with, but it's a bit unstable to use on the battlefield."

It is not easy to control the direction, and the take-off conditions are harsh. These are relatively big disadvantages. If possible, Xiao Zirong may prefer to use a hot air balloon.

It's just that I haven't found a particularly good material to make the spherical part of the hot air balloon, so I simply made a flying kite to play with, and it doesn't fly too high, just to let Xiao Xuexing feel it.

It turned out that Xiao Xuexing would send Feiyuan to the battlefield before Xiao Xuexing felt it.

Only then did Xiao Xuexing understand that he originally thought that Xiao Zirong was a flying kite to deal with Yuan Ke.

Although it is a good quality to be prepared for a rainy day, the problem is that if Xiao Zirong is thinking about Yuan Ke, Xiao Xuexing will not be very happy.

It turned out that Xiao Zirong wanted to take him to the sky to play, but he didn't use it and used it to beat Yuan Ke.

Yuan Ke was indeed his lifelong enemy.

Xiao Xuexing looked up at Feiyuan flying higher and further away, and suddenly thought of a very serious question: "How will they come back?"

Xiao Zirong said: "If the flying kite has speedbrakes, it will usually use the speedbrake to slow down first, and then the operator on the flying kite will control the altitude to come down a little bit, but this time it is too hasty, not all places are suitable for flying kites to land. place, so it is necessary to do a good ground survey.”

In fact, this is also very demanding for the operator, and Xiao Zirong has only a dozen of them who are good at flying kites.

After Feiyuan landed, Xiao Zirong took Xiao Xuexing to look at it.

It wasn't obvious when I was watching the flying kite take off, but when I got closer, I realized that the flying kite was very huge, and the all-steel frame looked very heavy.

The whole flying kite has a triangular shape, the whole body is black, even the steel frame is black, with a mysterious atmosphere, and there are baskets for placing items and a seat on it.

Xiao Xuexing walked around the flying kite a little bit inconceivably: "It's so easy to fly?"

Xiao Zirong stood aside and said: "It looks simple, but many things in it have been done after many experiments. The lift and resistance of the air and even the weight of the operator have to be taken into consideration."

Xiao Xuexing patted the slightly crude joystick in front of the gondola and asked, "This is for controlling the direction?"

Xiao Zirong nodded: "Feiyuan is different from others, it is not easy to directly control the flying wings, so this one uses the operator's own weight to control the direction and landing."

Xiao Xuexing walked around the flying kite, the more he looked at it, the more itchy he became, and he really wanted to fly to the sky to have a look.

Xiao Zirong hesitated for a while and said: "This thing is not easy to control, the flying kite for two people is not ready yet, it may not be easy to fly up now."

Xiao Xuexing turned to look at him: "Isn't it controlled by weight?"

"It's not to control the direction, but to control the landing. Taking off is easier than controlling."

In fact, the protective measures hadn't been done yet, so he didn't dare to take the risk of letting Xiao Xuexing fly into the sky.

Xiao Xuexing also understood and said with emotion: "It would be great if I could control the landing on the water."

If you don't fall directly from a very high place, then the buffer of landing on water is definitely stronger than on land. Even if there is danger, you can rescue. The only thing you need to worry about is how to ensure the safety of entering the water.

Xiao Zirong couldn't help but have a flash of inspiration when he heard this sentence: "Landing on water? Equipped with buoys, really, why didn't I think of it?"

He hugged Xiao Xuexing happily and said, "Brother is so smart!"

Xiao Xuexing looked at him and asked again: "Also, I took a look. Since it needs a run-up to take off, why bother to find a high place? Is it feasible to use a car as traction?"

Xiao Zirong blinked, this... seems to be really good, and later generations will also use other means of transportation as traction.

He couldn't help but kissed Xiao Xuexing in his arms and said, "Honey, you are a genius!"

He turned around and asked people to experiment with the possibility of using a car for traction. Today's car engines are more powerful than before, and the speed per hour has also increased a little.

Although the gearbox is still very simple, at least it is there.

The only thing to worry about is whether you can drag such a flying kite.

Xiao Zirong asked someone to turn the car over to try it out. Fortunately, the pulleys on Feiyuan were flexible enough to allow the car to be dragged without much effort. However, the paragliders were not used to it at the beginning and did not adjust Feiyuan in time. Orientation prevented takeoff.

After getting used to it, the pulleys of the flying kite gradually lifted off the ground. When the glider found that it was almost the same, he dropped the traction rope on the flying kite, and then adjusted the position a little bit, and finally let the flying kite fly to a similar height as before.

Xiao Zirong's eyes lit up: "In this way, Feiyuan's requirements for the venue will be greatly reduced!"

The next step is to train the glider for fixed-point delivery. These glider not only need to have a strong physique, excellent eyesight, but also must understand certain physics knowledge.

After all, it is very complicated to take into account the wind speed and relative motion when throwing mines from high altitude.

Fortunately, Xiao Zirong didn't require them to be very precise, as long as they were within a rough range. Anyway, there was a high probability that they would throw mines at the enemy's barracks, or the city lord's mansion, the area of ​​which was not small.

Two months later, dozens of flying kites were slowly transported to the front line.
