"Drive!"

Put on the saddle, the two of them rode on the white horses, and immediately gave a soft shout, and the two horses immediately galloped side by side.

"Restore the law!"

As he passed the lake, the Pegasus King neighed, and a group of wild horses galloped after the two horses.

Riding horses in the prairie, Yunyi and the big girl go hand in hand, the cloaks of the two are floating with the wind in the wind, galloping in the whole world is green, the wind whistles from the ears of the two, and a group of wild horses behind them rumble across the entire grassland, flooding with an overwhelming green wave, so that the posture of the two is so relaxed and freehand at this time.

"Wow, it's so beautiful, so romantic, how nice it would be if I could live like this with the man I love?"

On the edge of the grassland, a group of tourists suddenly looked at Yunyi and the eldest girl with surprise on their faces, what a happy thing it should be to ride a white horse with their beloved and gallop on a white horse.

"These horses are so beautiful, where did this kind of horse come from in the steppe, it doesn't seem to be a Mongolian horse?"

The tourists who knew the goods looked at the horses that Yunyi and the big girl were riding, as well as a group of horses following behind them, and suddenly wondered

The next morning, five aircraft logistics support vehicles of the Dadi Company drove over, mainly pulling several tons of aviation gasoline and some maintenance and support equipment.

Along with them came four spraying planes, the current and the one that had arrived before, all parked in a row in the open space on the other side of the small lake.

Five planes lined up in a row, exactly corresponding to five support vehicles, ground crew, gasoline and equipment on one car, enough to ensure that an aircraft can work continuously for ten days without the support of an airfield in the field.

"Hey, Mogg, climb up and shoot it, the fan blades of this plane are so big!"

A group of children from the Evenki tribe climbed up and down the plane in a strange way. Look at this plane with three propellers in front and a pair of big wings.

The boys and girls of the tribe also looked at the plane with novelty, except for the occasional passenger plane flying very high in the sky, this was the first time they had seen the plane that could be close in front of them and let people touch it.

"High Priestess, you are so powerful, you can find so many planes at once, we have never seen planes before!"

Yunyi took the big girl's hand. As soon as he and Harada and the others came over, a group of girls and boys from the tribe respectfully gathered around.

"Hehe, in the future, our Evenki tribe will have its own small plane, if you like it, let you sit on it and feel it!"

Looking at the reverent eyes of these girls and boys, Yun Yi smiled slightly and promised that he had already planned to go back, and he would either pay Chen Wei to help him build a few planes, or buy a few.

However, it depends on Chen Wei's obsession with building airplanes. should take over his own work, after all, he used to build his own airplanes purely for hobby and fun, and he had to invest his own money; Now he pays for him to build it, which is not only to satisfy his hobby. You can make a lot of money, so why not do it.

After saying a few words to the young people in the tribe, Yun Yi talked with the director of the Earth Company for a while, and worked out a plan for the spraying of the plane.

A total of five planes came from the Dadi Company. Their aircraft generally fly at a speed of about 30 meters per second and a width of about 13 meters during spraying operations.

Here's how it works. Each aircraft can spray an area of 490 square meters per second, and the spraying area is about 2,000 acres in one hour.

Because of the very simple structure of this agricultural aircraft and the slow speed of the engine, under the maintenance of a support vehicle, it can work intermittently for about ten hours a day, so that an aircraft can spray 20,000 acres of grassland a day.

Five planes can spray 100,000 acres of grassland in one day, and as long as all the planes are working, the entire grassland can be sprayed in four days.

After discussing the spraying route and plan with the person in charge of the Dadi Company and the ten pilots, Yun Yi and the others began to make preparations.

The grassland of Evenki has a total area of 270 square kilometers, which is 270 million square meters when converted into square meters; According to the aircraft spraying operation, the general amount of water sprayed per square meter is two grams, and the water requirement for spraying the entire Evenki grassland is about 540 tons.

For the 540 tons of water sprayed, the pumping machines on the five cars were all working; However, instead of pumping water directly onto the plane as they normally would, a large pool of water with a total volume of 500 cubic meters was built on the ground with steel pipes and waterproof canvas.

An airplane, a landing sortie flight for half an hour, can be 1.8 tons of water sprayed all, according to a sortie after spraying, ground staff inspection and maintenance for five minutes, and then change two pilots to continue to carry out the task, and a total of 20 sorties a day to calculate, a plane can spray 36 tons of water a day, spraying an area of 20,000 acres.

The pumping machines on the five cars pumped water into the simple pool, while Yunyi poured a bag of casually bought compound trace elements into the simple pool, and then 'personally' took a stirring stick to stir it inside, and then took the opportunity to mix his calculated space spring water into the pool.

"Mr. Yun, you don't need to stir this, when our pump pumps pump water to the plane, the pump will automatically stir the medicine well!"

Seeing that Yunyi was such a 'noble big man' busy in person, the person in charge of Dadi Company came up to remind Yunyi diligently.

"Hehe, you don't understand, this trace element is special, as long as it is stirred unevenly, then sprayed on the grassland, there are too many places where the grass will burn to death, and some places are useless if they are not dissolved, so you can't be sloppy!"

Yun Yi waved his hand with a serious face and continued to stir, but he said secretly in his heart: Ya, if my brother doesn't find this opportunity to mix things into it, can he still add private goods to it openly.

Because the pumping power on the five vehicles is not very large, in order to save time, before the water in the pool is full, a support truck is freed up, the pump pipe is placed in the pool, and then the first plane is filled with water.

"Water is full, ready to take off!"

When the water was full, a ground crew immediately waved the red flag and ran to the nose of the plane, and after making a 360-degree action with the red flag, the first plane immediately started the engine.

Immediately, the ground crew immediately squatted on the ground and waved the red flag forward, and the plane immediately slowly accelerated forward.......... (to be continued......
