Qin yuan looked at the books in front of him, but he didn't know that Du Juan had such careful thoughts, so he directly said to Du Juan:

"Now that we have come, let's find all the books we need at one time."

Qin yuan really believed Dujuan's words. After all, he felt that if these were only basic knowledge, I'm afraid even if they were recycled, it would be impossible to obtain more advanced skills, so he thought that if he could recycle some advanced books, he might be able to obtain more advanced submarine knowledge!

But after hearing this, Du Juan's eyes stared directly at the boss. Some people looked at Qin yuan angrily, but she didn't say anything. She turned her head directly to collect those data!

Du Juan's chest can't stop fluctuating at this time. She originally wanted to take this opportunity to straighten Qin yuan and let Qin yuan see this knowledge and see that her head is big.

But who could have thought that this guy had directly seen through his plot and asked himself to prepare some more advanced materials. Obviously, this guy didn't intend to read these books. He asked himself to prepare those advanced materials just to help himself!

Otherwise, there are enough books in front of Qin yuan. Qin yuan, a rookie, wants to read them for at least a few days and nights. As a result, he still wants them now. Isn't that obviously difficult?

However, the official college level crushed people. Although Du Juan was full of anger, she still prepared some more advanced materials and planned to send them to each other.

At this time, the daughter-in-law smiled when she saw that the cuckoo had gone, and then recycled the books in front of her into her own space!

After all, these are the knowledge Qin yuan has never touched before, so Qin yuan is not stingy. He plans to spend more squares to see if he can write down all these knowledge!

"Ding Dong ~ system recycling succeeded, please start selecting!"

With the prompt sound of the system, the three options immediately appeared in front of Qin yuan!

"1. Obtain the foundation of world-class submarine soldiers!"

"2. Obtain the design drawings of world-class submarines!"

"3. Obtain world-class submarine driving ability!"

At this time, seeing these three options, Qin yuan hesitated a little, and then chose item 1.

After all, Qin yuan doesn't need to operate the whole submarine alone this time. Qin yuan can't drive all the submarines alone. All he needs to know is what everyone needs to do.

As for the design drawings and driving ability of items 2 and 3, Qin Yuan plans to see if cuckoo can bring some other books, and then make a choice.

"System! I choose item 1! "

"Ding Dong, the host selection is successful and has won the foundation of world-class submarine soldiers."

With this sound, Qin yuan immediately felt that there was more turbulence in his mind. These are some basic knowledge about submarines, and these knowledge is just a little complicated, but not deep, and there is little pressure on his brain.

So the daughter-in-law smiled. Sure enough, her choice was right. This so-called submarine soldier foundation is equivalent to an encyclopedia of submarine soldiers. Any knowledge about submarines can find some basic answers from this.

Although it is not useful for submarine research and development, it is enough for Qin yuan.

Finally, the daughter-in-law made a series of choices and directly promoted these basic knowledge to the cosmic level. After reaching the cosmic level, Qin yuan not only had more profound views on these basic knowledge, but also felt that he had more experience in driving submarines!

Qin yuan was pleasantly surprised. He saved a lot of time. It is estimated that he should know more about submarines than the submarine soldiers who have driven submarines all their life!

At this time, Du Juan came over with a face and a pile of books, smashed them on the table and said to Qin yuan:

"Report chief, I have brought all the books you need. If you need more advanced books, you can only go to the research institute or the comprehensive research institute!"

Qin yuan nodded when he heard these words, and then he directly opened the more advanced books of Du Juan. Later, he found that he could understand them, and he had deeper opinions than books, so he knew that it was no longer necessary to collect these books.

"Well, in that case, let's go back first."

With these words, Qin yuan stood up directly and wanted to go, but the cuckoo behind Qin yuan asked Qin yuan with an ugly face:

"Chief, are we going to borrow all these things back? You borrowed a little too many books this time. I'm afraid it's not suitable? "

At this time, the cuckoo almost scolded Qin yuan to death. This is a tall book. Do you have to move it to the counter by yourself?

Although Du Juan is a staff officer, she usually stays with commander Zhang. Commander Zhang is an old researcher. She is considerate of them. In addition to working overtime, she even thinks about her. However, the family in front of her is completely different. It seems that she really regards herself as a little attendant!

You know, I'm a master in the submarine major of the advanced Naval Academy. If you compare my understanding of submarines, I'm much stronger than your old cap marine!

But in this case, the cuckoo would never say it directly. She could only ask Qin yuan the above words with a face!,

The daughter-in-law looked back at the books and understood the cuckoo's embarrassment. However, after reading the name on the book from one side, he directly took out two copies from the book and said to the cuckoo with a smile:

"I'm wrong. I mean, as long as these two books are enough, the others don't need!"

what?

Hearing this, the cuckoo widened her eyes. What is the boy doing? Are you kidding me? He worked hard to find this pile of books, but he said no, so he didn't?

Moreover, Du Jian looked at the two books in Qin yuan's hand and gnashed his teeth. One book is all kinds of anecdotes about submarine soldiers and the other is the development history of submarines in various countries. These two books have a fart effect on Qin yuan's work!

Obviously, this guy doesn't intend to read at all, but just use these two books for recreation!

At this moment, the cuckoo couldn't bear it, and directly said to Qin yuan:

"Chief, is that how you treat this mission!"
