At this time, Qin Yuan looked at these books in front of him, but he didn't know that Du Juan had such careful thoughts, so he said directly to Du Juan:

"Since we are here, let's find all the books we need at once."

Qin Yuan really believed in Du Juan's words. After all, he felt that if these were just basic knowledge in front of him, it might not be possible to obtain more advanced skills even if they were recovered. So he thought, if he could recover some advanced books, maybe Able to acquire more advanced submarine knowledge!

But after hearing such words, Du Juan's eyes stared directly at the boss, some of them looked at Qin Yuan angrily, but she didn't say anything, and turned her head to collect the information!

Dujuan's chest of anger couldn't help rising and falling at this time. She originally wanted to take this opportunity to take a good look at Qin Yuan and let Qin Yuan look at this knowledge and see that her head was big.

But who could have imagined that this guy would directly see through his own strategy and let himself prepare some more advanced materials. Obviously, this guy didn't plan to read these books. He asked himself to prepare those advanced materials just to support himself. !

Otherwise, there are enough books just in front of him. Qin Yuan is a rookie. It would take a few days and nights if he wants to finish reading it, but it turns out to be more now. That's not obvious. Embarrassing?

However, the senior officials crushed people to death. Although Du Juan was full of anger, he still prepared some more advanced materials and planned to send them to the other party.

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

After all, these are knowledge that Qin Yuan has never touched before, so Qin Yuan is not stingy, and plans to spend a few more squares to see if he can remember all of this knowledge!

"Ding Dong~ The system recovery is successful, please start to choose the host!"

With the prompt sound of the system, three options suddenly appeared in front of Qin Yuan!

"1, get the foundation of world-class submarine soldiers!"

"2, get world-class submarine design drawings!"

"3, get world-class submarine driving ability!"

Seeing these three options at this time, Qin Yuan hesitated a little, and then chose the first option.

After all, this time it is not necessary for Qin Yuan to operate the entire submarine alone. It is also impossible for Qin Yuan to drive the entire submarine by himself. All he needs to know is what each person needs to do.

As for the design drawings and driving ability of items 2 and 3, they are relatively advanced abilities. Qin Yuan intends to see if Dujuan can bring some other books later, and then make a selection.

"System! I choose item 1!"

"Ding Dong, the host chooses successfully and gains the foundation of a world-class submarine."

With this voice, Qin Yuan suddenly felt that there was a turbulence in his mind. These are some basic knowledge about submarines, and this knowledge is just a bit complicated, but not profound, and the pressure on the brain is not Not big.

So my wife smiled slightly. Sure enough, my choice was right. This so-called foundation of submarine soldiers 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 the research and development of submarines, it is enough for Qin Yuan.

Finally, the daughter-in-law made a series of choices and directly upgraded these basic knowledge to the universe level. After reaching the universe level, Qin Yuan not only had a more advanced insight into these basic knowledge, but also felt that his hands seemed to It is a lot of experience in driving a submarine!

This is even more of a surprise to Qin Yuan. This time he saved a lot of time. It is estimated that he knows more about submarines than the submarine soldiers who have been driving submarines for a lifetime!

At this time, Du Juan was also pulling a face, holding a stack of books, came over, hit the table heavily, and said to Qin Yuan:

"Reporting 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!"

And Qin Yuan nodded when he heard such words, and then he directly opened the more advanced books that Du Juan later found, and found that he could understand them, and he still had deeper insights than books, so he knew these. There is no need to recycle the book anymore.

"Okay, since that's the case, let's go back first."

Having said this, Qin Yuan stood up directly, and then wanted to leave, but the cuckoo behind Qin Yuan asked Qin Yuan with an ugly look:

"Chief, are we going to borrow all these things back? You borrowed too many books this time, I am afraid it is not suitable?"

At this time, Cuckoo almost cursed Qin Yuan to death in his heart. This is a book that is full of height. Do you have to rely on yourself to move it to the counter?

Although Dujuan is acting as a staff member, she usually stays with Commander Zhang. Commander Zhang is an old researcher, who is quite sympathetic to them~www.mtlnovel.com~ Besides having to work overtime, what's so delicious? The one who is delicious even thinks of her, but the guy in front of him is completely different, as if he really thinks of himself as a little follower!

You must know that my old lady is a master of submarine major in the Advanced Naval Academy. If you compare your understanding of submarines, you will be much stronger in your army!

But in this case, Du Juan wouldn't say it directly, so he could only ask Qin Yuan the above words with his face drawn! ,

And the daughter-in-law looked back at the books at this time, she also understood Cuckoo's embarrassment, but after reading the name of the book from one side, he pulled out two books directly from it, hehe smiled and said to the cuckoo:

"It's wrong, I mean just two books are enough, nothing else is needed!"

what?

Hearing this, Dujuan's eyes widened. What is this kid doing? Are you kidding me? He worked so hard to find this huge stack of books, but he said he didn't want it?

And Du Jian looked at the two books in Qin Yuan's hands, gritted his teeth even more. One book is about various interesting stories about submarine soldiers, and the other is the history of the development of submarines in various countries. These two books are about Qin Yuan. Work has a fart effect!

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

This time, Du Juan couldn't bear it completely, and said directly to Qin Yuan:

"Chief, are you treating this mission like this!"
