However, Ruan Haocheng did not feel as relaxed as Chen Zhiyun, and the solemn expression on his face when Mr. Ming and Company Commander Fang were talking this morning always made him feel that what they were going to learn in the future was not relatively simple things such as telephones and telegrams, but he couldn't figure out what it was.

"It's likely that we're learning something that we didn't know before, so it must not be that easy for us to learn."

Ruan Haocheng poured cold water on Chen Zhiyun first, and then turned to Chen Ziqiang, "Ziqiang, you are relatively good at circuits, and you will make up for the three of us in the future." ”

"No problem, if you don't understand something, just ask me." Chen Ziqiang suddenly felt full of confidence.

"Zhiyun, let's go to the data room tonight to check and see if we can learn more about the tools related to circuits and the tools that must be used in the barracks."

Chen Zhiyun had already put away the joy on his face and nodded solemnly, "Okay, then we'll go now." ”

As soon as they left, the four of them walked out of the dormitory and walked towards a two-story building on the edge of the office building, where the first floor was the training equipment store, and the second floor was the library.

On the second floor, there are four large libraries, one is a reading room for military novels, one is a basic science library, another is a reference book library, and the last room is a modern science library.

On the wall at the entrance of each library is a detailed description of the library materials in the library.

They first went to the basic science library, and according to Mr. Ming's request, they found out the relevant materials and recorded them in the notebook handed to them.

Then, at the suggestion of Ruan Haocheng, they came to the modern science library.

In addition to monographs on the results of modern scientific research, there are also the latest periodicals and newspapers.

Because there are very few recruits with a junior high school education or above, there are many people in the basic science library just now, who are like them and come to check the materials according to Teacher Ming's requirements, but there are few people in other libraries.

In this modern science data room, apart from the four of them, there was only one administrator sitting behind a desk, about twenty-seven or eighteen years old.

Seeing the four of them walk in, Comrade Administrator suddenly came to his senses, hurriedly stood up and greeted him.

"What information do you four want to see, I'll show you the way."

Chen Zhiyun, who was walking in front, looked at Ruan Haocheng beside him, "What kind of information are we going to see here?" ”

Ruan Haocheng smiled gratefully at the administrator, and then said to Chen Zhiyun: "Let's take a look at the advanced inventions in the military in recent years, as well as their promotion and application!" ”

"Is a rocket launch considered a military invention?"

Chen Zhiyun remembered what Wu Yingjie said to him last night, and it seemed that he was about to understand what the Wu battalion commander specially invited Teacher Ming to teach them in the end, but he felt a little unable to grasp the clue.

Because he thinks that they may learn something similar to that of rockets and their launch systems, but definitely not them, because they are not at that level.

"Military inventions are not only rocket launches, but also many things that everyone does not know, such as communication radars, military aircraft, military ships, etc."

The administrator began to list to them the military inventions of our country in recent years.

Communication radar? Ruan Haocheng's heart couldn't help but light up.

Airplanes, ships, and rockets are too far away from them, but this communication radar seems to have been heard of by him, and it should be more commonly used in the military!
