Xu Lang clicked his tongue, "Can it be magnified ten times?"

"Yes, as long as there is enough space, enlarging it ten times is not a problem; because what needs to be purified are factors that cannot be measured in the air, so it requires huge absorption and transformation capabilities, so it will appear bulky."

"No, no, it's not bulky at all." Xu Lang shook his head repeatedly. He had seen the smallest purification system, and he couldn't say anything bulky. Thinking of this, Xu Lang asked: "Minghua, the purification system is so big, how big is it?"

Isn’t it heavy in your hands when you are little?”

Minghua shook her head, "It's not very heavy. It has space technology inside and will bear all the weight."

"It's so easy to carry, it can be big or small; it's easy to use and you can take it with you wherever you go. You have done a great job again." Anyone with some knowledge knows that the pollution on the earth is indeed becoming more and more serious now.

Minghua pressed a button on the purification system, and the entire purification system shrank to its smallest size again. She handed it over to him, thus completing the task.

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

After sending Xu Lang away, three days later, Xu Lang brought someone to pick her up in person and took her to the most polluted place in the country; that is, the border between Province G and Province C, where a cement factory was built, and it was the largest in the country.

A cement factory's daily output is measured in tons.

Minghua saw that the air here was very polluted, and even the surrounding land was so polluted that it was impossible to plant. She had no choice but to rely on the government to help, but the pollution in the air could be solved. Once the purification system was installed,

At the highest point of the cement plant, when the purification system is turned on, the air, originally invisible to the naked eye, becomes a visible landscape due to the concentration of many pollution factors.

During purification, the purification system has a screen similar to a TV; there is data on how much has been purified, the running time, and the purification status. In a small corner of the screen, you can see a little bit of the purification process.

"Let it run for half a month first, and then look at the situation of the cement plant after half a month. It is best to have experts follow to collect data in the air." Once in and out, data is the best proof material, "The purification system was first born.

, observe more, it’s best if there are no loopholes; only if there are loopholes, you can find them as soon as possible.”

"My uncle has reported your intention to you; I was asked to bring these to you by the higher ups. Take a good look at it. You will be admitted to the capital next year and work hard to move forward. I hope that one day you will stand thousands of miles away and protect our motherland.

." Xu Lang saluted.

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

A talent who can use space technology to do scientific research, how good is her physics, chemistry and mathematics? They all know her information, and it can even be said to be clear. From her academic performance since childhood, to this time she was

Rapid progress after breaking his head.

"Then do you have any ideas to continue scientific research next?"

It also reassures them.

There is no such good thing as space technology in the world today. Foreign countries want to study it, but they still have no clue. It was only a high school student who researched it.

They couldn't exchange a few words until they left the cement factory.

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

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

It’s absolutely fine to work part-time while studying.

After sending Minghua home, he reported the matter when he returned. After the superiors heard about it, they asked him to cooperate fully and give her all the information she needed. He also tried his best to help her learn diplomatic matters.

You don’t have to wait to study for a doctorate before joining the Ministry of Foreign Affairs. You can join as an intern after graduating from university.

"What aspiration!" Xu Lang said dryly.

Minghua shook her head, "No, I have learned five foreign languages. Does Uncle Xu think I am just learning it for fun? I have already planned a path for myself; after graduating from university, I want to study for a PhD and enter the Ministry of Foreign Affairs.

Be a diplomat."

So, when they met again, Xu Lang brought her a large box of diplomatic information; including the diplomatic history of his country and other countries, as well as photos, habits, and various hobbies of foreign diplomats.

.

Could it be that Minghua succeeded in using countless genius techniques? This shows how useful her brain is; the questions he asked naturally had no answer.

If people abroad know about it, don't vomit blood.

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 and bright side to others.

"It's not that troublesome. I made it for ease of use. It's natural to make it as convenient as possible." Walking down the high ground, they were followed by a group of leaders of the cement factory; they understood what the two said, but they couldn't get in.

Mouth.

"I will make materials on space technology and hand it in. It is not impossible to learn if you want to. The prerequisite for learning space technology is that you have to master physics, chemistry, mathematics and other subjects to a certain extent. Otherwise, you will not be able to keep up with calculations and operations.

"Then how long will she have to spend it? It's a waste of time.

"I don't know. There is no standard for me to test." What Minghua said left Xu Lang speechless.

The air above the cement factory is seriously polluted and the effect will not be seen for a while.

On the way to send Minghua back in person, Xu Lang asked: "Minghua, can the purification system be mass-produced? The space technology you mentioned."

Doing diplomatic work is not something you can do by sitting in one place and just talking. It needs to be done from many aspects.

I haven’t seen her study or work hard, but she can easily cope with the exams and her grades are at the top of the list. Apart from these, she is learning five foreign languages, plus Chinese chess, calligraphy and painting, so she can also cope with it.

freely.

If you have that time, why not go to the trading center to trade some useful things.

The air is sucked into the purification system, and clean air is released after purification; fresh air is continuously produced to remove unknown impurities in the air.

He only saw her press three buttons, and the purification system was automatically installed and started running with one click.

They don't have it, only Minghua knows it.

Minghua bowed in return, "Thank you, Uncle Xu. I will take a closer look. I wonder if Uncle Xu is here just to deliver information, or for other matters?"

"There is something, but I just said it, so you can't be angry." Xu Lang said.

"Uncle Xu, although we have been working together for a long time, we won't get angry over trivial matters."

It’s not something trivial to be angry about!

Xu Lang coughed lightly, and under her gaze, he hesitated and said, "The purification system you developed has received feedback from the cement factory. The workers working there felt that the air was much better; it would not make the body uncomfortable just by breathing.

It turns out it’s really useful.”
