Cavalry battalions? That's fine, let's see how the training goes.

Qian Fei'er thought to herself, chuckled and nodded.

"Okay, then it's time for Marshal Goron to lead the way."

"The last will obey." Goron replied respectfully.

Subsequently, Qian Fei'er and Xue Ye visited the cavalry camp again, and it was not until the evening that Qian Fei'er drove Xue Ye back to the palace in a car.

Because it was driven back to the city from outside the city, there were no people on this short stretch of road, so Qian Fei'er stepped on the gas valve a little wider.

The valve was stepped on widely, and I could only hear "Boom!" With a roar, the rear wheels of the car rotated at high speed, carrying Qian Fei'er, Xue Ye, Qian Xinyu, and Qian Yueqi to the Tiandou City at a rapid pace.

Because the throttle, to be precise, the valve is pressed to the end, and the speed is very fast, close to more than 100 kilometers per hour!

Xue Ye sat in the passenger seat, watching the road in front of her instantly become larger, and suddenly she was frightened, and hurriedly shouted: "Aifei, slow down, slow down, don't fly too fast!" ”

It was the first time for Xue Ye to experience such a fast speed, and for a while, his heart was in his throat, for fear that Qian Fei'er would hit something.

Fortunately, although Qian Fei'er drove a fast train to catch the shrimp household, she didn't hit anything, and after entering the city gate safely, she slowed down and moved forward slowly.

Only then did Snow Night breathe a sigh of relief, and his face was covered with sweat.

Behind him, Qian Xinyu and Qian Yueqi didn't react, as the owner of the Angel Martial Soul, flying at high speed is instinctive, at such a speed, neither of them will blink their eyes.

Xue Ye turned his head to take a look, and couldn't help but sigh again and again.

The angel martial soul is just good, and there is no panic at all......

In this way, the journey was spent in the emotion of a snowy night, and after a while, Qian Fei'er successfully drove back to Xuelin Palace, just in time for dinner.

Qian Fei'er took Xue Ye and others into the Xuelin Palace, and called her sloppy cousins Qian Liuli and Qian Yuqiong, and several people shared a table in the small courtyard and had dinner together.

At the dining table, Qian Fei'er was picking up vegetables while thinking about how to make the plane.

Compared with cars, airplanes are much simpler to make than cars as long as they know the principle of flight.

First of all, if an airplane wants to rise into the sky, it cannot do without pressure.

The flight wing design of the aircraft is designed to curve upwards upwards in a convex way, and the bottom is designed to be flat and horizontal.

The wind is coming head-on from directly in front of the plane, and it accelerates as it passes over the curved surface, and the wind flies faster.

In contrast, the customs of the plane below remain unchanged, and they are slower in comparison.

If it is slow, the pressure will be large, the pressure below will be strong, and the pressure above will be small, and the air will form a "thrust" from the bottom to the top, lifting the plane into the sky.

As for the oncoming wind, the propeller rotates the air at high speed, and the air swirls to form the wind.

The propeller is connected to the gas motor, and the motor is connected to the turbofan, which is the gas internal combustion engine.

The internal combustion engine provides kinetic energy, and after a series of energy transfers, the aircraft can take off into the sky.

The whole principle is very simple, but Qian Feier did not want to build a propeller plane.

She wants to build ...... Jet planes, direct slightly propeller this stage!

Jets.

Qian Fei'er groaned slightly in her heart, picked up a piece of bamboo rat meat with skin with chopsticks, and put it in her mouth.

The skin of the bamboo rat meat is elastic and the meat is strong, with a lot of chili pepper and condiment aroma, which is very delicious.

Qian Fei'er took a bite, took a bite of food, and continued to think in her heart.

Jet aircraft, the principle of flight is basically the same as that of propeller aircraft, both use pressure to lift the aircraft into the sky.

The difference is that the wind required by the propeller aircraft to fly into the sky is provided by the high-speed rotating air of the propeller.

Jet aircraft, on the other hand, have a jet engine mounted on the rear or wing, which uses strong thrust to propel the aircraft forward at high speed.

In the process of rushing, it is natural that an oncoming strong wind will form.

Strong winds blow head-on, and the wings of the jet and the propeller aircraft are exactly the same, both of which are convex and flat at the bottom.

In the same way as propeller aircraft, the oncoming strong wind is slow below, fast above, and the atmospheric pressure below will be greater, which can lift the aircraft into the sky.

It seems simple to say.

However, Qian Fei'er knows that it will not be easy.

First of all, in order for a jet to sprint on the runway, the speed must be sufficient.

More than 100 kilometers per hour is not enough, it must be faster, otherwise the wind will not be strong enough.

At this stage, the biogas internal combustion engine she uses to build a car is far from powerful, and the gas emitted is not strong enough to propel a behemoth like an airplane into a high-speed rush.

So, how about superimposing multiple internal combustion engines in parallel? Or increase the volume of the internal combustion engine and introduce more biogas, while maintaining a certain amount of the size of the vent and not allowing the vent to expand to obtain more powerful thrust.

If you think about it this way, maybe it will work.

Well......

Qian Fei'er decided to start the experiment tomorrow.

And just when Qian Fei'er was thinking about the principle and process of making an airplane while having dinner, on the other side, in the extreme east of the Heaven Dou Empire, Qian Linjue and Qian Nawei had almost arrived at their destination.

Heaven Dou Empire, Eastern Duchy.

At this time, the eastern principality had entered a relatively deep night, almost eleven o'clock in the evening, close to twelve o'clock, that is, the sub-hour.

The Douluo Continent is vast, and there is a huge gap across time zones, and Heaven Dou City is still around six o'clock in the evening, and it is already late at night here.

In a clearing not far from the riverbank, Qian Linjue, Qian Nawei and others were having dinner together.

They traveled a long way during the day, and at night they were also rushing with the light bulb invented by Qian Fei'er, and they didn't stop until not long ago. 228 Literature Network

In the clearing, people sit on picnic cloths with various delicacies on them.

There are grilled chickens, fish stews, wild boar meat, and more.

Qian Linjue held the bowl in her left hand and chopsticks in her right hand, sandwiched a piece of chopped roast chicken, and took a bite of the rice.

The roast chicken is very dry, the moisture inside has basically been roasted, it is very dry and fragrant, and the skin has a little smoky burnt taste, and even a little crispy.

As soon as you bite into it, you can hear a clear crunch sound, and the mellow aroma unique to the chicken is brought out, and the texture and taste are excellent.

He took a bite satisfied, then put the chopsticks in his left hand and held them with the bowl.

Holding chopsticks in his left hand, he picked up a plate of fish stew in front of him with his right hand, poured the plate over, and poured the fish juice into his rice bowl.

When the fish is stewed, the umami of the fish meat mixed with the flavor of other spices will run into the juice, which is a rare delicacy.

Next to Qian Linjue, sat Nangong Yan, who had long blond soft hair and a little short and thick eyebrows.

When she saw Qian Linjue pouring fish juice bibimbap like this, she immediately felt very fresh and novel.

It was the first time she had seen fish eat like this.

Since childhood, Nangong Yan's parents have told Nangong Yan that if you want nutrition, you will eat meat, and if you want deliciousness, you will drink soup.

As for the juice of the stew, don't touch it.

It contains a large amount of dissolved salt, and eating it will consume a large amount of sodium in a short time.

Supplementing too much sodium is not a good thing, it will cause some bad reactions in the body, such as neuropathy is caused by excessive nitrite, and the main ingredient is sodium nitrite.

Therefore, Nangong Yan has never eaten stewed vegetable juice since she was a child, and there is no nutrition in it.

"Can you eat this?"

She looked at Qian Linjue and blinked twice curiously.

Qian Linjue turned her head arrogantly to take a look, didn't speak, and directly took a bite of rice with fish juice.

The fish stew has a strong garlic flavor and is filled with fried garlic grains.

At the same time, it is also very spicy, and if the fish wants to get rid of the fishy smell, the chili pepper is indispensable, and a large number of chopped peppers can now be seen on the plate of fish.

And this spicy is not simply spicy or spicy, but also a mixture of sour, sour and spicy.

Add sour bamboo shoots!

In addition, there is the taste of spices such as sand ginger, star anise, mixed with sour, hot and garlic, sour and spicy, and fragrant, and the bibimbap is very delicious.

Qian Linjue only took one bite and enjoyed it all over her face.

Nangong Yan saw Qian Linjue's expression, and her eyes were full of little stars.

"Wow, it's so good, I want it too!"

As she spoke, she also picked up the fish plate and put some juice into her rice bowl.

The juice is earthy yellow, and the rice in Nangong Yan's bowl is also dyed earthy yellow.

Curiously, she picked up some with her chopsticks and put them in front of her to look at them.

The surface of the rice reflects an oily luster under the light, and it can be seen that it is very slippery.

The grains on top are even, and it looks no different from ordinary rice, not much different.

Is it really delicious?

She put it to her mouth curiously, and sniffed it.

The rice mixed with fish juice exudes a sour and spicy stimulating taste, which stimulates people's appetite, and as soon as they smell it, Nangong Yan begins to secrete saliva automatically in his mouth.

It looks like ...... It's really delicious!

She thought to herself, and then tried to open her cherry mouth and take in the rice mixed with fish juice.

The rice was as sour and spicy as her mouth, stimulating her soft little tongue to throb.

At the same time, it is also accompanied by a strong flavor of fish, and the deliciousness of the fish is volatilized to the extreme under the background of chili peppers, sour bamboo shoots, garlic granules, and various spices.

"Hmm~"

Nangong Yan closed his eyes and tasted it.

But then, she opened her eyes, couldn't wait to chop the rice, and inhaled while shasha.

This fish stew is made with a lot of chili peppers, and a considerable part of the spicy flavor of the chili peppers is incorporated into the fish sauce.

It's spicy!

Another point is that the sour bamboo shoots inside are very sour, and the more you eat them, the more you want to eat them.

This made Nangong Yan show the scene of constantly gulping down rice.

It's really delicious!

Nangong Yan is very happy, it is the first time she has eaten stewed fish like this since she was a child, and it is also the first time she has tasted such a delicious taste.

Next to her, Qian Linjue turned her head to look, didn't speak, turned her head, and continued to eat.

After a while, when dinner was over, a soul master came over and took the dishes away and took them to the river bank to clean, while the rest of the people went into a state of cultivation or rested.

In a tent.

Nangong Yan sat cross-legged in the tent, and Qian Linjue leaned back to her reading comics.

He actually wants to do something to Nangong Yan now, and wants to give his beloved wife the best caressing.
