Generally speaking, breast milk is the best food for babies after birth; This is not speculation, nor is it casual nonsense, but the reason for hundreds of thousands of years of human evolution has made the best food for babies to eat is breast milk.

It's just a pity that the current breastfeeding rate of infants in China is less than 30 percent, which is of course the reason why modern women love beauty and are reluctant to breastfeed babies for the sake of their figure; But more of it is the false and shameless propaganda deliberately made by milk powder merchants for their own interests.

And some unscrupulous bricks, relying on the reason that they are intellectuals, can propagandize, saying that 'breast milk is only nutritious, and there is no nutrition in the later stage, and breastfeeding milk powder is more nutritious', deliberately misleading the Chinese people are unwilling to use breast milk - breast milk babies.

It's just that there are many people who understand this, such as Luo Xiaoyun, who insists on breastfeeding her children.

After a rest, plus a little nutrition, although Luo Xiaoyun's spirit was still sluggish at this time, she still insisted on doing it, and at the same time let the two little guys allow the two little ones to suck their breasts at the same time.

Seeing the sweetness of the two little guys sucking with their eyes closed, and a little wrinkled little mouth sucking one by one, a huge sense of happiness rose from Luo Xiaoyun's heart, she looked up and wanted to share this joy with her man, but she noticed that Yunyi was staring at herself intently.

"Hey, have you seen enough?"

Luo Xiaoyun's words suddenly made Liang Qingqiu, Yunyi's mother, Long Xiaotian, and the eldest girl in the single senior ward turn their heads, and immediately found that Yunyi was still here.

"Eh, that, Sister Luo, your Mi-Mi is so big, no, it's the two little guys who eat it so deliciously"

Yun Yi explained in a panic, this is not how many people are looking at themselves.

Thinking like this, Yun Yi turned his head and found that a group of masters had already gone out. I'm left standing here.

"You kid, hurry up!"

Long Xiaotian rolled his eyes, Yun Yi hurriedly ran out embarrassedly, and Luo Xiaoyun's low and funny voice came from behind him.

"This group of old guys, don't pull me when they come out!"

When he went out, Yun Yi glanced at a few old guys, all sitting on chairs outside the door talking and laughing.

Because they were twins, Luo Xiaoyun and the two little ones stayed in the hospital for three days, and only after the two little ones were very lively did they return to Qingyun Mountain Village under strict protection.

The reason why I am in such a hurry to come back. The main reason is that Qingyun Mountain Village is more suitable for recuperation than the hospital, whether it is the landscape environment and air of Qingyun Mountain Village, or the chicken, duck, fish, meat, fruits and vegetables provided by Yunyi, which are incomparable in the hospital.

Because of the previous agreement, after Long Xiaotian returned home with his daughter-in-law and children, Yunyi immediately moved to the wine jar Qingshan Brew as a congratulatory gift, and for Luo Xiaoyun's health, he also deliberately sent a pound of precious honey from the space, as well as black oil fish and white fish in the space. As well as large river mussels and other good things with high nutrition.

After being busy for a while, the day was late April, and Yun Yi was also in a hurry to go to Hulun Beier, where the temperature on the prairie had recovered at this time. Yun Yi had to quickly arrange for the people in the tribe to start spraying the space spring, buying cows, and vegetable fields in the western suburbs of the capital.

If you want to go to Hulun-Beier, the three planes that Chen Wei built will inevitably be brought over. Because by the end of May, when the grass has grown on the grasslands, there will be 10,000 cows, and there will be more than 200 grasslands of nearly 300 square kilometers in Evenki. It is necessary to use such light aircraft to patrol.

The last incident has already taught Yunyi a sober lesson, and Yunyi was not a threat at that time, but with these 10,000 cows and the impact of tenfold expansion, it is difficult to guarantee that your company will not regard Yunyi as an opponent.

Therefore, Yunyi has to guard against it!

"Yunyi, you see, I used the front trainee pilot to control the plane by fly, and the coach in the back seat can use the mechanical wire rope to control the plane when necessary, as long as the coach behind grasps the control handle, the front fly-by-wire control system will be automatically cut off!"

On the threshing floor, Chen Wei was explaining to Yunyi the principle of the two-seat ultralight training aircraft; At the beginning, the fly-by-wire control system and training system to be used in this two-seater training aircraft really gave Chen Wei a headache for a long time.

It wasn't until one day that Chen Wei saw a few students in the academy making their own model airplanes, which gave him an idea, and adopted the method of using the battery driving the auxiliary servo system in the front and the mechanical system in the back.

This thing seems a bit complicated to say, but in fact it is very simple, the so-called fly-by-wire control system used by the previous trainees is not the kind of fly-by-wire on the third-generation fighter, but similar to the kind of fly-by-wire on the remote control aircraft, and the different scales on the front handle are connected with different control wires, so that the auxiliary system in the back can control the aircraft with a servo motor.

"For this training plane, I used a 45-horsepower gasoline engine, which made the maximum speed of this training aircraft reach about 180 kilometers per hour, and the maximum cruising speed was 120 kilometers per hour.

The aircraft is designed with a small fuel tank and two large auxiliary fuel tanks that can be removed.

This design makes it possible to remove two large auxiliary fuel tanks in normal times, and a standing small fuel tank can fly for three hours with a full tank at a time, and can fly about 300 kilometers at an economical cruising speed.

If you need to sail over a long distance, you can fly more than 3,000 kilometers after adding two large auxiliary fuel tanks, which is enough for you to fly to the Hulun-Bei-Er steppe! ”

Chen said something, which made Yun Yi excited, and then he asked the remaining two ultralight aircraft, their power is slightly smaller, only thirty horsepower, and the maximum speed is only one hundred and ten kilometers, but with the same fuel tank design scheme, a single pilot can also fly three thousand kilometers at a time.

"Brother Yu, you are so amazing, so careful!"

Yun Yi excitedly touched the plane, these three planes were all used by Chen Wei almost completely enclosed plastic steel glass, which is enough for people to fly the plane in winter without feeling cold, and can also fly to an altitude of several kilometers.

"You kid's business, can I use more snacks!"

Chen Wei said with a smile, Yun Yi was a little moved, but frowned again:

"By the way, Brother Chen, Brother Long will definitely not be able to get out, how can I get these three planes!"

"I want to help you, but it's too cold to fly over this way, and if there is nothing on the road to warm up, it won't work!"

Chen Wei sighed faintly, and said as if it was a pity.

Yun Yi looked at Chen Wei's expression, listened to his strange words, and suddenly understood what Chen Wei meant, and said with a smile;

"Brother Yu, you helped me build these four planes, not to mention the money saved, it is the time and trouble saved that have helped me a lot, I don't have much Qingshan brew there, but it's no problem to give you three jars!"

Chen Wei was stunned for a moment, his face was suddenly full of surprise, his hands rubbed back and forth embarrassedly, and grinned:

"It's too much, it's too much, just give me one jar, three jars are too many, I'm really embarrassed to take so much!"

Yun Yi smiled, he had to give Chen Wei three jars of Qingshan Brew, but Chen Wei was killed because he was only willing to ask for one jar of Qingshan Brew, Yun Yi also understood that he was worried about others, and he let go of one jar of Qingshan Brew after the last.

At noon that day, Yun Yi and Chen Wei were ready to go to Hulun Beier, the three planes were filled with fuel, and they also put on thick clothes.

As for the piloting of the last plane, it was handed over to the two sophomores of high school, who were Chen Wei's assistants, and after applying for extracurricular practice requirements in the college, the two students piloted the training plane and flew in line with Yunyi and Chen Wei on the way to Hulun-Bei-Er.

I have to say that Chen Wei's level of manufacturing aircraft is getting higher and higher, and the ultralight aircraft under Yunyi's crotch has improved a lot in terms of power and workmanship, as well as many designs, and its maneuverability and other indicators have surpassed the aircraft that Chen Wei made for himself.

Of course, all this comes at a price, and in order to ensure that the engines of the three planes do not be picky, Chen Wei deliberately chose the engines on the second-hand Bao-Ma motorcycles.

Such engines are cheap, and their performance and quality are even better than some poor-quality aero engines, which makes Chen Wei believe that as long as these three ultralight aircraft do not have accidents, even if they are three or five years old, they will not need to be overhauled.

The maneuverability of the three planes is quite good, not long after Yun Yi piloted the plane to take off, it was flying high and low in the valley, if it weren't for the fact that the two large auxiliary fuel tanks did not have a pressurization function, he would even want to have a horizontal scroll.

Compared with the last big plane, the average speed of the three small planes is much more flexible, under the leadership of Yun Yi, the four of them flew at a maximum cruising speed of about 120 kilometers per hour, except for finding a flat place at night to land and rest a few times, basically did not stop much along the way.

Three days later, as the temperature dropped significantly, the four of them finally arrived in the Evenki steppe, and Chen Wei and the two students were warmly welcomed by the Evenki people.

In late April, the temperature in the Evenki steppe is very high during the day, and there are already many pastures on the steppe that have sent out tender green buds, making the steppe look beautiful and beautiful.

"The grassland here is so beautiful, you kid is really blessed!"

Standing on the prairie, Chen Wei is not only full of envy, but the scenery here is undoubtedly much more beautiful than the grasslands in other places on the road to Hulun-Beier.

After coming to the grassland, Yun Yi was immediately busy teaching Hai Lincha to fly an agricultural plane and began to spray the space spring water he had concocted, while Chen Wei drove a training plane to train the young people of the Evenki tribe to learn to fly this small plane.
