"Got it?" asked Major Niu after getting into the car.

"Well, I've got it. Wang Xiaodian started the car and drove outside the science and technology zone. Unlike the careful inspection when entering, visitors leave the tech zone almost unimpeded.

The military jeep sped all the way to the temporary garrison of Reps, and after entering the camp, you could see that the soldiers here were very busy, and since the camp was going to be pulled out tomorrow, the soldiers had already begun to pack their bags.

Niu Kelian took Wang Xiaodian into the temporary office, and after instructing the sentry not to let anyone in, Major Niu took out a notebook.

"Give me something. Major Niu stretched out his big hand, and the second lieutenant couldn't help but say after putting the USB flash drive in the major's hand: "It was really exciting just now, this is the first time I have done such a thing." ”

"Really?" said Major Niu, "Isn't covert operations also a compulsory subject in military schools?"

"How can that kind of class in school compare to real action? Major, you didn't see it just now, my action is absolutely perfect. Wang Xiaodian helped his glasses, quite complacent.

"For the first operation, it wasn't bad. Major Niu plugged the black USB flash drive into the computer and said, "It's just that the opportunity to go to the bathroom was not very good at the beginning, and it was a bit sudden." ”

"Yes! I'll pay attention next time. The lieutenant was still excited, but her attention was quickly drawn to the papers on the USB stick.

Major Niu opened the folder, which was mainly a variety of record files, and under these files, there were also some photos and videos.

Major Niu clicked on the photo, which showed a large area of crops that seemed to be cultivated without soil, but on closer inspection, these crops were not really cultivated without soil.

The roots of these crops are neither in the nutrient solution nor in some kind of substrate, but are all exposed to the air!

"Is this vacuum farming?" Wang Xiaodian asked in surprise, "Is this place all vacuum?"

"Probably not, you look over there, there seems to be a staff member, he is not wearing any special equipment, this may be an ordinary environment. "Niu Kelian had heard that the White Eagle Laboratory had engaged in a vacuum farming, and now he has seen the true face of this kind of farming.

But when he saw that the roots of these crops were all exposed to the air, but the crops were still growing lush, he was still very shocked.

"Those... The roots of the plant are directly exposed to the air like this, how do they grow?" Wang Xiaodian said suspiciously: "Could it be... These plants have just been taken out of the nutrient solution? These pictures were deliberately posed?"

"Probably not. Major Niu said: "I have heard that the vacuum breeding of white eagles is to expose the roots of plants directly to the air. ”

"Are they really exposed to the air?, so how do they absorb nutrients?" Wang Xiaodian felt that the photo in front of her was a bit subverted to her cognition, plants mainly rely on the root system to absorb nutrients, these roots are neither in the soil nor in the nutrient solution, how do they grow?

"That's the problem. When Major Niu heard this, he said: "Due to the invasion of monsters, the crops in the subcontinent have declined very badly, and many traditional crops have become extinct, but the white eagle invented vacuum farming, and cultivated many crops that cannot grow in the subcontinent. ”

"Really?!" Wang Xiaodian was even more surprised: "This is really amazing." ”

"yes, the information in this should be very valuable. Major Niu said, "Well done, Xiaodian." ”

"The major has won the award, if it weren't for the internal response inside, we wouldn't have been able to get the USB flash drive so smoothly. Wang Xiaodian was not greedy for merit, she asked: "Major, how can we hand over this USB flash drive?"

"I'll do this, before tomorrow morning, I'll hand over the USB flash drive, now, I'll find out what else is in it. Major Niu's gaze moved away from the computer screen: "Xiaodian, you've worked hard for the past two days, go back and rest and rest, you're going to leave here tomorrow, what supplies do you need, hurry up and buy them now." ”

"Yes, then I'll go out first. Wang Xiaodian did have some things to buy, and they rarely made it to such a big city on their next trip, so she had to buy some necessary supplies that couldn't be obtained elsewhere.

"Go ahead, remember to call your father. Major Niu watched Wang Xiaodian leave, and then he refocused his attention on the computer.

At this time, Niu Kelian was the only one left in the room, and he opened the drawer on the desk and took out a white USB flash drive from it.

The Major plugged the USB flash drive into the computer and copied all the files from the black USB flash drive into the white USB flash drive. After copying the documents, the Major put the white USB stick in the pocket of his jacket, unplugged the black USB stick again, and put it in an envelope.

After placing the envelope in the briefcase, the major turned off the computer, and after a short rest, he got up with the briefcase and went to the door of the tent, opened the door and walked out.

The sky gradually darkened, and Niu Kelian walked straight to the jeep in the afterglow of the setting sun, but at this moment, Wang Xiaodian happened to come over.

"Major, you go now... Wang Xiaodian was carrying a military backpack, obviously planning to make a purchase.

"Well, hand it over early, and feel more at ease. The major got into the car, but Wang Xiaodian stood next to the car but did not leave.

"Xiaodian?" Seeing that she was still not leaving, the major immediately asked, "Is there anything else?"

"Major, I want to go to the business district in the center of the city and give me a ride. Wang Xiaodian said with a grin.

"Uh... I'm here to get down to business. "The Major obviously didn't want to take her with him.

"It's not far, just take me for a ride, it's getting dark. Wang Xiaodian continued to request.

"Okay, come up. Seeing Wang Xiaodian's earnest words, Niu Kelian had no choice but to agree. Wang Xiaodian saw that Niu Kelian agreed, and immediately got into the car happily.

Major Niu started the car and drove towards the city center.

"Can I put you here?" the major stopped at the edge of the city center.

"Yes. Wang Xiaodian opened the car door and walked down: "Thank you, Major." ”

"Well, go back sooner. Major Niu gave some advice and drove the car out.

Wang Xiaodian saw that the car was getting farther and farther away, so she took out a mobile phone from her pocket, and after unlocking the screen, she clicked on an app.

After the app was running, the phone's screen went black, and then a dense grid appeared, Wang Xiaodian tapped the screen a few times, and a floor plan of the Columbia District appeared under the grid, and at the same time, a slowly moving red bright spot appeared on the phone screen.

"Where is the Major going?" Wang Xiaodian looked at the screen and walked towards the business district.
