Xu Lang smacked his tongue, "Can you magnify it tenfold?"

"Yes, as long as there is enough space, magnifying ten times is not a problem; Because what needs to be purified is a factor that cannot be fathomed in the air, so it requires a huge amount of absorption and transformation capacity, so it will be bulky."

"No, no, not bulky at all." Xu Lang shook his head again and again, he had seen the smallest appearance of the purification system, and he couldn't say bulky words; Thinking of this, Xu Lang asked, "Ming's wife, the purification system is so big, isn't it heavy to hold in your hand after it becomes smaller?"

Ming Wu shook her head, "It's not very heavy, there is space technology in it, and it will carry all the weight."

"It's so portable, big or small; It's easy to use, you can take it with you wherever you go, and you've done a great job again." Anyone with a little insight knows that the pollution on the earth is indeed getting heavier and heavier.

Ming Yu pressed a button on the purification system, and the entire purification system shrank to a minimum again; Give it to him, and the task is done.

"Ming, come on, try to make more things." Before leaving, Xu Lang did not forget to encourage him.

sent Xu Lang away, and after another three days, Xu Lang took someone to pick her up in person to go to the most polluted place in the country; That is, on the border between provinces G and C, where a cement plant was built, and it was the largest cement plant in the country, with daily output measured in tons.

Ming Yu saw that the air in this place was so polluted that even the surrounding land was so polluted that it was impossible to plant; She has no choice but to rely on ZF to help the pollution on the ground, and the pollution in the air can be solved. The purification system is installed in the highest place of the cement plant, and the purification system is turned on, which is invisible to the naked eye. Because of the concentration of many pollution factors, it has become a landscape that can be seen.

At the time of purification, the purification system has a screen similar to that of a television; There is a lot of data purified in it, the time of operation, and the purification status. In a small corner of the screen, you can see a little bit of the purification process.

Of course, it's just a small process, not all.

The air is sucked into the purification system, and after the purification is completed, the clean air is released; A steady stream of fresh air is generated to remove unknown impurities from the air.

The air above the cement plant is seriously polluted, and there is no effect for a while.

"Let it run for half a month, and then look at the situation of the cement plant after half a month, and it is best to have experts follow to collect data in the air." One in and one out, data is the best proof material, "The purification system is just born, more observation, no loopholes are the best; If there is a loophole, you can find it in the first place."

It is also to reassure their hearts.

Even if she doesn't say these words, the people above will still find someone to observe; It's better for her to take the initiative and leave a bright side.

Xu Lang nodded, "Okay, but does the purification system just need to be placed in a suitable place?"

He only saw her press three buttons, and the purification system was automatically installed, and it was turned on with one button.

"It's not that troublesome, I made it for ease of use, naturally how convenient it is." Walking down the high ground, they were followed by a group of leaders of cement plants; They understood what the two said, but they couldn't interject.

Until they left the cement plant, they couldn't say a few words.

On the way back to send Ming Wu in person, Xu Lang asked, "Ming Wu, can the purification system be mass-produced?" What you call space technology........"

They don't have it, only Mingwu will.

"I will make space technology and turn it in, and it is not impossible to learn it if I want to; The premise of learning space technology is to have a certain level of knowledge in physics, chemistry, mathematics and other subjects, otherwise, you will not be able to keep up with the calculation and operation." How long does it take for her? It's a waste of time.

If you have that time, you might as well go to the trading center to trade something useful.

Xu Lang thought thoughtfully, "Then how far have you learned?"

What is the level of physics, chemistry and mathematics for talents who can use space technology to do scientific research? Their information, they all know, can even be said to be clear. From childhood to adulthood, to the rapid improvement after being hit on the head.

I didn't see it

No matter how she studied, she didn't see her work hard, but she was able to cope easily in the exam, and her grades were at the top of the list; In addition to these, she is learning five foreign languages, coupled with the qin, chess, calligraphy and painting of Chinese culture, and people can cope with it easily.

"I don't know, there's no standard for me to test." Ming's words made Xu Lang speechless.

At present, there is no such good thing as space technology in the world, and foreign countries want to study it, but they still have no clue, and they are stunned by a high school student.

If you let those people abroad know, you must not vomit blood.

Could it be that countless genius techniques, Ming Wu has succeeded, which shows how good her brain is; Naturally, the questions he asked had no direction to answer.

"Do you have any ideas for continuing your research?"

Mingwen shook her head, "No, I learned five foreign languages, does Uncle Xu think I learned to play?" I've mapped out a path for myself; After graduating from university, I will go to graduate school and enter the Ministry of Foreign Affairs, and I will become a diplomat."

"Good ambition!" Xu Lang said dryly.

sent Ming Wu home, and he reported the matter when he returned; After hearing about it, she only asked him to fully cooperate, and she gave her all the information she needed, as long as they had. I did my best to help her study foreign affairs, and she didn't have to wait for her to study for a doctorate before entering the Ministry of Foreign Affairs, and she could go in for an internship after graduating from university.

It's perfectly fine to work and study.

So, when they met again, Xu Lang carried a large box of diplomatic materials for her; Among them, there is no shortage of diplomatic histories of their own countries and countries, as well as the photographs, habits, and hobbies of foreign diplomats.

Diplomatic work is not just a matter of sitting in one place and talking about it, but requires a lot of work.

"Your intention, Uncle has already reported it to you; These are all brought to you by the above, you can take a good look, be admitted to the capital in the coming year, and work hard. I hope that one day you will stand thousands of miles away to protect our motherland." Xu Lang saluted.

Ming Wu returned a salute, "Uncle Xie, I'll take a good look at it; I wonder if Uncle Xu came here this time just to deliver information, or if there is something else?"

"There's something, but you can't be angry." Xu Lang said.

"Uncle Xu said that our cooperation time is not short, so we won't be angry about a little thing."

It's not a trivial thing to get angry!

Xu Lang coughed lightly, and under her gaze, he hesitated and said, "The purification system you developed has received feedback in the cement factory, and the workers working in it feel that the air is much better; It doesn't make the body uncomfortable when you breathe, so it can be seen that it is really easy to use."

"That's a good thing!" Could it be that someone is greedy for the purification system?
