"Brother~ It's really interesting~"

Xinke covered her mouth and smiled lightly. Her smile was not hazy and had no acting skills, which made her confused when she noticed her smile through the refraction of the water droplets in the sky. Why did she have such a smile?

Just like when she was troubled in the past, she couldn't help but look back on her past experiences. When she looked at the mirror in front of the table, she found that the corners of her mouth turned up involuntarily. This unconscious smile also confused her when the water all fell back. , she sat on the edge of the bathtub and gently slid the water in the pool.

Why deliberately tease? Surely it's for fun, right? There is also a bit of revenge, deliberately running in knowing that Yongye will not accept this kind of behavior.

Ah, but to be honest, even so, she wasn't attracted to her, and she was a little annoyed that she was inferior to others when she knew that the goal of Yong Ye was simply not evil? It just ran away.

Xin Ke, who didn't care about trivial matters at all, stepped into the used pool without any taboo, closed his eyes and started thinking wildly.

Yong Ye above, put on the clothes that he had prepared, and began to meditate again, but instead of recovering his body, he became familiar with knowledge.

Frankly speaking, the Storm Sword Saint and the Promise Sword Saint, who were level 5 and level 6, have now all become level 7. In fact, there is no leap-forward improvement except for the use of annihilation energy.

In the final analysis... He is not restricted by the level, he just gained new knowledge. Even if the full-level Storm Sword Saint and Wuji Sword Saint appear, he doesn't think he will be defeated.

The existence value of the system is only to provide knowledge, and his various knowledge is enough, but the knowledge is not too little, and the skills of the system are really useful, or...very useful.

…

Evening, dinner time.

Xinke Nierbalen, who was supposed to be a research madman, went to the room of her house occupied by Yong Ye, knocked on the door and asked Yong Ye to go down for dinner.

"Brother~ I am very confident in today's fried potato chips, please eat more~!"

Xin Ke, who was sitting opposite Yong Ye, recommended potatoes to Yong Ye with a smile. He seemed to be in a good mood, but Yong Ye couldn't help but patted his forehead and sighed.

"...You didn't do this, why are you confident?"

"Ah~ I hate it~ How can you be so sure? It's been two months since I've been gone, maybe I'm going to study~?"

"Don't talk about the impossible, I'm not stupid enough to believe that you can cook, it's just a self-discipline puppet doing it..."

Xin is a research madman, and he is the kind of person who can make himself half-starved without anyone taking care of himself, so Yongye can only give Xinke the self-disciplined maid puppet that he planned to use for himself, which is convenient for supervising and promoting food. Can also cook.

For such a person, Yong Ye naturally wouldn't believe that she could cook or cook, but compared to these messy things, it was Xinke's current state that confused him.

"By the way... Have you made progress in your research? Have you been smiling all the time?"

"No~"

"Then what happened?"

"Hmm~ Guess what?"

Pressing her index finger against her pink lips, the girl narrowed her eyes and smiled happily.

"No... I'm still not guessing. Compared to this, I would like to give you a suggestion, such as adding something else to the spirit-destruction technique."

Xinke's expression made it clear to Yong Ye, who had known each other for more than two years, that if this topic was discussed at this time, this ordinary matter would definitely become more difficult, so he changed the topic.

"Brother, is it okay to change the subject like this?"

"…Well, what do you mean?"

Although Xinke deliberately glared at Yong Ye with her cheeks puffed up to express her dissatisfaction, Yong Ye still pretended to be confused, ignoring her expression, and went on talking on her own.

"The Ex-Machina's ability is very strong. If your spell is copied, it will become very troublesome. Those uncreative mechanical copying ability is very strong, but I have studied their ability, and they can only copy the elves. use."

"It can only be used on elves?... I'm sorry brother, the elves in this world are everything, is that enough?"

Although he didn't want to let Yong Ye go easily, this topic actually made Xinke very concerned. No one would want his research results to be copied at once, so the issue of anti-theft is indeed very important.

"It's a very simple thing. In the magic spell, it's good to add magic that doesn't belong to this world, and don't use elves... only creatures can use magic."

"Hmm~? Huh?"

Xin Ke was a little puzzled, but she quickly thought of something, and looked at Yong Ye with bright eyes.

If Yongye is willing to teach her the magic of other worlds, then mix the magic structure with the magic of this world, even if it is just mixed, as long as it is designed in an inseparable form and mixed into the core of the Ex-Machina It is impossible to copy.

As for the anti-theft ability of this method, Yong Ye can be sure, because the magic on the magic side is magic that cannot be used by machinery, otherwise Academy City would have created a lot of magicians long ago. After all, Artificial Intelligence was also created in Academy City.

Now you just need to mix the magic in the regular sense with the magic of using spirits, and it's not a problem. The creatures can use it, but the machines cannot. The Ex-Machinas who specialize in elven magic can't even analyze that kind of magic.

"Brother! Teach me the magic of another world!"

Xin Ke stood up and leaned his upper body over the table.

"Let's talk after dinner, don't worry, take your time... I'll organize a book."

Pressing his hand on the face of the girl who was in high spirits, Yong Ye pushed her back directly, without any feeling of pity.

...No matter what the memory is, as compensation, Yong Ye decided to spend time teaching Xinke magic. I believe that with Xinke's aptitude and her own powerful abilities, it shouldn't be difficult to learn magic... It shouldn't be difficult, right?

It is impossible to teach the whole teaching. There are too many things. If Yong Ye himself dictated it, it would take too long, and it would be impossible to learn all of them. There are 103,000 magic books. His choice is to find one that suits her. Well, anyway, it's just mixed into the technique, so it doesn't need too much, right?

And the content of the magic book is mixed into it. If you forcefully read it, you will damage yourself, whether it is a human or a machine... Just like a normal person will have a nervous breakdown just after reading a little bit of content, the pure original content is just the content. It can also be turned into a murder weapon.

"Speaking of which... why is the food in your place still vegetarian every time I get seriously injured?"

Thinking that the content of the magic book is the same as above, Yong Ye, who flipped the potato chips, looked at the vegetables and fruits on the table, and couldn't help complaining.

"Do you want to eat meat, big brother? Then I'll kill two demons~?"

Xin Ke tilted his head and said seriously.

"No... I don't want to eat life with a certain intelligence. It feels weird, so forget it... Well, it's good to be a vegetarian."

Although the monsters are not very intelligent, they are intelligent anyway. The lowest types of monsters are ogres or trolls. Thinking about it makes Yongye lose his appetite.

"Then eat quickly~?"

"Yes, yes... But you just want me to give up eating meat, right?"

"How is it possible~"

"...Absolutely."

Yong Ye stared at Xin Ke and complained about her behavior, but Xin Ke avoided the conversation with a smile.

In this way, Yong Ye took Xin Ke, who had long been unable to bear the temptation of unknown magic, to enter the basement again after dinner, but this time, instead of taking a bath, he went to the research room.

After a simple test by Yongye, the conclusion was similar to what was expected. Xinke's aptitude as a magician is very strong, um...because she is also a magician herself, but the energy used is different.

After Yong Ye's careful selection, she finally picked out three of the 103,000 magic books for her to study. I believe she shouldn't be able to bear all three of the original books. After all... her spiritual power is beyond Ordinary people, in the adult religion, he did not find an existence with stronger spiritual power than her.
