"I am the knight of His Highness Yuphemia, Anzbrill. Kyo, nicknamed Bai Qi, I'm here to find someone, please let me in. Pen "Fun" Pavilion www.biquge.info" Bai Qi said at the door,

At this time, the people on the side looked at the man wearing white and red clothes at the door, and found that he was:

"Isn't this the knight of His Highness Yuphemia? How did it end up here? ”

As he spoke, he took two photos with his mobile phone.

However, because there is still a certain gap between knights and civilians, Bai Qi is now considered a soldier, and his military rank is major.

"Please wait." The security guard made a phone call and said something. Then the security guard immediately opened the door,

"Please come in, the head of the academy can't entertain you now, please forgive me."

"It's okay, I'll find it myself, so I won't trouble you."

"Feel free to .....," the security guard said respectfully,

Bai Qi walked into the campus that he was familiar with as always, but Bai Qi didn't go straight to the point, because now that class was over, it was also troublesome to find Nina. I don't know if it's in the lab, in the classroom, or in the office of the student union, so Bai Qi can only look for them one by one......

The students passing by suddenly saw a stranger in white here, and suddenly felt a little strange:

"Who is this? Familiar......"

"It's not .... Yesterday on TV the knight of Her Royal Highness Euphemia Anz Blie. Kyo? How could it be here?!! ”

"Are you here to find the head of the house?"

The people around looked at Bai Qi in amazement, which had never felt like this before.......

Due to their status, these students did not dare to say that they had come to greet Bai Qi. Even the children of those nobles have to look at the rank on the white body, it's not something they can afford to provoke, and it's not necessary, isn't it good to look at it from afar?

The students of Ashverd looked at Bai Qi one by one, of course Bai Qi didn't care about the eyes of these people, after all, what Bai Qi had to do now was to recruit Nina into the Knights and become a weapon developer in the Knights!

You know, Nina is a science madman in the later stage~~~

It is equivalent to the invention of an epoch-making weapon in this era, and it is equivalent to the power after the atomic bomb explosion, which is simply terrifying!

And in the end, he is one of the few people who know the 'Requiem of Zero Town', and he has a very rich knowledge that can become the technical guide of Yufermia's forces!

It is precisely because of Nina's unusual mind that Bai has come to the door of the student union first.

There is a motorbike parked next to it, surrounded by a garden, and it still looks so beautiful.

But there didn't seem to be anyone around, so Bai Qi walked in rudely.

There was no one in the hall, so Bai Qi walked to the office of the student union on the side, and sure enough, he saw the president Mi Lei, Xia Li and Livar.

Of course, there is Nina, who is busy calculating data graphs on the computer!

That's the purpose of Bai Qi..... However, those people were also a little panicked when they saw Bai Qi walk in.

"Teacher.... No, knight of His Highness Euphemia?!! Livar said that he had leaked his mouth, but Bai Qi ignored it,

"Hello, I'm the knight of His Highness Euphemia, Anz Breek. Kyo, nicknamed Bai Qi, is Miss Nina here? Out of politeness, Bai Qi still asked.

"Is there anything you can do?" Nina looked at the man in front of her and remembered the day when this man came to save her,

One person has solved all the residents of District 11, so amazing!!

But what did he come to himself for? Did you make a mistake?

Nina's heart was pounding, and she didn't know whether to be excited or panicked.......

"That's right, I would like to invite you to come to the Order of His Highness Euphemia and become a member of His Highness the Knights of Euphemia. I've heard that you're very good at physical chemistry, so I thought we could provide you with a very good experimental environment. ”

"What?! Why? The people around him said in surprise,

"I think Miss Nina has a very high level of theoretical knowledge, so I want to invite the Knights to contribute to Britannia...."

Nina was shocked, and she didn't seem to hear what she said in a trance.

Bai Qi said with a smile, looked at some strange charts drawn on Nina's computer, and said:

"It's uranium atoms, right? The ..... with a mass of 235"

"Ah, yes! Yes! You can understand it~~ If you let this uranium-235 absorb thermal neutrons, it will split into two nuclei and a light-speed neutron. However, the problem is that the uranium-235 used as a raw material is only 0.7% of natural uranium, and no matter how many devices are prepared to separate it, it will not be possible to do experiments if it continues like this, so...."Nina instantly remembered that she was facing a knight, and immediately covered her mouth,

"What a faux pas, I'm sorry, I'm sorry!"

"She's like that, she talks about everything when she mentions what she's good at, but she rarely talks about it." Mi Lei said with a smile.

Then the "hydrometallurgical process" should be used to process the ore into a chemical concentrate containing 60~70% uranium, and then further processing and refining. The chemical concentrate (ammonia diurarate) obtained by uranium water smelting is yellow, commonly known as yellow cake, but it still contains a large number of impurities, which cannot be directly applied and needs to be further purified.

To this end, ammonium diuranate is dissolved with nitric acid to obtain uranyl nitrate solution. It is then purified by solvent extraction to achieve the required purity standard. The purified uranyl nitrate solution needs to be heated and denitrified to convert to uranium trioxide, which is then reduced to uranium dioxide.

In order to produce uranium metal, uranium dioxide needs to be reacted with anhydrous hydrogen fluoride to obtain uranium tetrafluoride; Finally, uranium tetrafluoride is reduced with metal calcium (or magnesium) to obtain the final product uranium metal. If uranium hexafluoride is to be produced for uranium isotope separation, fluorine gas can be used to react with uranium tetrafluoride. Both uranium metal and uranium dioxide can be used as fuel, but more raw materials must be obtained to extract more uranium...... It's rude, I've forgotten what I'm here for. Bai Qi smiled bitterly,

Of course, my heart is really bitter, so it took two days to memorize the above words, although they are all some basic process methods, but as long as Nina can be excited, everything is easy to solve!

Nina looked at Bai Qi with a smile in her eyes: "It's okay, it's the first time someone is willing to talk to me about these things, I'm very happy." ”

"So, Miss Nina, would you like to come to the Knights of Her Highness Yuphimia to serve Your Highness?" Bai Qi smiled and looked at Nina's happy appearance, and this thing was done!

"Okay, I do." Nina said with a smile,

"It won't disturb your personal time, if you want to take classes at any time, you can come to the military laboratory at any time, if you have any needs, please tell us, we will try our best to meet you."

Someone will pick you up tomorrow, please contact me if you have any questions. So the faux pas, bother you. ”

After Bai Qi finished speaking, he turned around and went back first.

"Nina, are you really going to the military?" Xia Li said worriedly,

"Well, because many of the materials I study in the college's laboratory are not available, I hope to have a better research environment.....," Nina said, her voice uncontrollably excited,

"Oh? Isn't it to get close to your savior? Mi Lei looked at Nina jokingly, and Nina didn't dare to say anything......

"Ah~~ You guys are so good, you all have something to do, I'm idle all day, Lelouch doesn't know where to go to play recently, and he doesn't take me with him......" Livar grumbled on the side, bored and said,

"you! If you have time to get busy with the work in the college, are you two still in the student union?!! Mirei smashed a book on Livar's head. Livar looked at Mirey in pain,

"It's so painful, president, what do you want us to do when you're done....."

"You're still reasonable!!"

There was a flurry of chickens and dogs jumping in the student union office.......

Bai Qi, who went out, looked outside, thinking that the first person had also solved it, so the next thing was to confiscate something.....

Bai Qi smiled bitterly, in fact, Bai Qi would rather not do this if he had time, but the establishment of the knights is imminent, and everything that should be prepared must be prepared!!
