This morning, in order to speed up the purification of reagents, after eating breakfast, Lan Yu almost trotted in the direction of the chemistry museum.

She was going to replace Ivan in the experimental classroom, and he had been on duty for nearly twenty hours straight.

School is about to start, and students are returning to school with their luggage on campus. Lan Yu, even when she saw the faces she knew, she just nodded hastily, afraid that she would delay Ivan to go to breakfast.

When he arrived at the chemistry hall, Lan Yu saw a strange jeep parked in the courtyard. She ignored it and went straight into the hall.

When I approached the door of the experimental classroom, I found that the door was hidden.

Lan Yu was just about to push the door to enter, when a strange man's voice came from the room, it was a thick local accent that Lan Yu was not very familiar with. Because the bobbin sound is very heavy, you can hear it clearly when you stand in the corridor, and the voice of the bore voice speaking:

"Let me tell you Ivan, in several local wars after the Cold War, their Chinese army was extremely overwhelmingly controllable. Ivan, do you know that they dare to kill openly and unscrupulously against their enemies, isn't it because they are superhuman in the field of X-alloy technology? “

Again, the bobbin is saying:

"Of course, our X raw ore export business has also started recently. However, at present, the control of the entire international market is still monopolized by the countries of the United States, Youzhou, and Rus. ”

I only heard Ivan take over and say:

"These X mineral resources are not only indispensable raw materials for many important high-tech products, but also non-renewable resources. If there is no planned circulation, or indiscriminate mining and blind development, it will not only lead to a decrease in the total amount of resources in the future, but will certainly cause serious problems such as wanton destruction of the mainland's ecological environment. If we want to solve this problem, we can only start from scratch and take into account the advanced achievements of our country and learn from foreign countries, which is one of the important purposes of this experiment. ”

"So, don't snub me, kid." Chambering said.

Lan Yu listened to the conversation between these two people, and now he roughly understood the significance of Ivan coming here to replace the training. Under the leadership of Ivan, through this research group, Lan Yu was fortunate to participate in the information analysis experiment of relevant strategic resources.

Now, Lan Yu is bent on cooperating with this project.

X mine has the reputation of "industrial vitamin", which is widely used in petroleum, chemical industry, metallurgy, textile, ceramics, glass, permanent magnet materials and other fields, and is a lubricant for many high-tech industries such as electronics, laser, nuclear industry, superconductivity, etc.

Once these are used in the military, they will inevitably bring about a leap forward in military science and technology. For example, the tactical performance of steel, aluminum, magnesium, and titanium alloys used in the manufacture of tanks, aircraft, and missiles has been greatly improved.

At present, in the mainland, the X mineral reserves account for about 23% of the world's reserves, but it is responsible for more than 90% of the world's market supply.

However, the development of domestic industries has fallen into internal and external troubles.

For a long time, the problems of environmental pollution, low resource utilization efficiency, and lack of core technologies for related product research and development have restricted the planned and sustainable development of the industry in the region.

In the conversation she overheard, she learned that the completion of this experimental task is of great significance to the protection of the resource reserves in the mainland's territory, and to the protection and balance of the survival and ecological environment, and that the study of the protection and development of these strategic mineral resources has a bearing on the country's reality and future security.

For Ivan, it is the sacred responsibility and obligation of him and his comrades-in-arms to protect these important local resources related to national defense and security from being infringed upon by some evil forces at home and abroad, and it is also the bottom line of national security and interests.

In order not to disturb their conversation, Lan Yu jumped on the window sill opposite the entrance door of the classroom and sat and waited, intending to wait for them to finish this important conversation before going in. Because, as if she had heard Ivan giving him a detailed report on the progress of the experiment, he finally said:

"Chief, don't worry. In the near future, we are also focusing on collecting resource information and conducting experiments on relevant specified mineral samples, and satisfactory results will be expected in half a year. ”

"Well, I'm sure you'll be excellent."

After a while, the voice asked Ivan:

"Are you mentally prepared for where you will go after graduation?"

"It's been ready for a long time." I could hear that Ivan's voice was suddenly very low.

"Listen to Lao Ji, do you have a sweetheart? Hehe, boy. You can always bring this up and we will respect your personal choice. ”

"Chief, I will not hesitate to accept the task, and as for personal marriage, I will withstand the most severe test."

"Human sense. But if you're so promising, your father will be proud of you under the Nine Springs. "It seems that the chief also knew Ivan's father.

"I'll come back to see you. Do your best and get the best results. ”

This was the last sentence, and Blue Feather gently jumped off the windowsill and crept towards the bathroom next to her, trying to hide. But when he sent the chief out, he was still seen by one of Ivan's heads.

Lan Yu had no choice but to keep his head down and quietly slipped into the classroom.

There is Ivan's experiment log on the test table, she picks it up and flips it over, the work is neat and hierarchical, and she has a very strict logical thinking mind to make such an excellent experimental report.

This experiment log is a complete record of all experiments from the first experiment to today's moment since they first entered school as partners. Every operation and every piece of data recorded was done by the two of them.

This is not so much a diary of experiments as a love story that only the two of them can read.

Holding it is like seeing Ivan's voice and smile. However, Lan Yu can often find that Ivan's simple smile always hides a sadness that is not easy to be noticed by others.

Soon, all the happy past they had ever had would follow him somewhere far away, somewhere she didn't know where it was.

Lan Yu originally wanted not to be sad, but now she has tears in her eyes, just because her affection for him is too deep, she can only hope that her gentle nature will also be sent to the edge of the cape with him

"Uh-huh! What are you thinking about? ”

Blue Feather was frightened by the sudden sound and raised her head.

She suddenly realized, Ivan, he might have been standing there for a long time, why, now he is exactly the same as the image that just came to mind, Lan Yu really wanted to run over and hug him tightly, tell how much she loved him, and express that no matter where he went, he would follow him.

Lan Yu's heavy heart was discovered by Ivan, and in order to hide her eyes full of crystal tears, she lowered her head.

She heard Ivan at this moment suppress her sadness and said excitedly:

"Lan Yu, I know all about your thoughts, and you may have heard some of them just now. For the sake of faith, even if it is a trivial task, these are the missions we should shoulder. Do you agree? ”

Lan Yu nodded silently in approval.
