Han Kun shook his head, this elemental spirit was of no use to Han Kun at the moment, except for causing him trouble in the future. But it was also difficult for Han Kun to dispose of this elemental spirit, because this thing had no life or substance, no matter how many times you defeated it, it would regenerate, and if you wanted to completely annihilate it, you would have to attack the cold ice marrow of this entire lake, which would obviously outweigh the losses.

After figuring out the reason, it was time for Han Kun to leave. After going around the lake for a week, Han Kun was completely lost, but fortunately, he still had an indicator to find the direction he had when he first came, and it shouldn't be difficult to find his way out after spending time.

......

"Hey, am I asleep......"

Liu Yu rubbed her eyes and woke up from the sofa.

Around, it was still the warm room with a fireplace, but Han Kun had long since disappeared, leaving only Kailina on the side, flipping through books.

"Karina? How long have I been asleep? ”

"It's been almost six hours."

"So long?? What about Han Kun? ”

"He has some things that he has to go out and do. Rest assured, he'll be back soon. ”

"But it's still snowing outside......"

Liu Yu muttered quietly, and it was not difficult to see that she was worried about Han Kun. But since Han Kun had already decided to go alone, of course she wouldn't say anything.

"Seeing how worried you are, why don't we play a game?"

Karina closed the book in her hand and said to Liu Yu with a smile.

"Games?"

"Yes, a simple little game, there is a dice and a cup here. The rules of the game are: put the dice in the cup and shake the cup at will. The dice are cubes with one to six points on each side. You can choose how many points you want to guess the dice, or you can choose whether to guess whether the dice are odd or even. After the shaking stopped, the two told each other the answer in their hearts. If you guess correctly, the person who guesses wrong will answer a question from the person who guessed correctly, and if you guess correctly or incorrectly at the same time, it will be considered a loss. In addition, the person who guesses the number of points has a higher priority than the person who guesses the odd and even numbers, for example, I guess the number of points is three, you guess the odd number, and both of us guess correctly at the same time, but you still lose. If I guess it's an even number, you guess the number is two. If we guess wrong at the same time, then I lose. But if I guess it's singular, you guess it's two, I guess right and you guess wrong, then I win. How about it, if you understand the rules, are you interested in playing a few games with me? ”

"The rules are generally understood. Let's have fun, but don't cheat. ”

"It's the dice and the cups, you can double-check them. The dice and cups are made of black insulators, which are the best magic insulators that you can check for authenticity. When you're ready, put the dice in the cup, snap the cup on the coffee table, and you start shaking. ”

After Liu Yu carefully examined the dice and cup, he used a little magic to check the authenticity of the lower edge stone. After confirming that there was no problem, she shook the cup according to Karina's words.

After the shaking stopped, the two made sounds almost simultaneously.

"Even."

"I'm three."

Liu Yu was a little surprised, and Karina's voice did not hesitate, and directly reported an accurate number.

Take the cup away and the dice are exactly three.

"This ......"

In the process, Liu Yu did not feel any magic fluctuations, which means that Kailina did not use magic at all.

"It's just luck."

"Okay, okay, I lost this game, what questions do you want to ask?"

"How long have you known Han Kun?"

"A little more than a month, right? I can't remember exactly how many days. ”

"I see, let's start the next round. It's still you who roll the dice. ”

Karina always had a faint smile on her face, and she brought a sense of dignified elegance to Liu Yu.

The dice stopped, and the two said in unison again:

"Even."

"Six."

Once again, Karina was convinced that she had given an accurate number.

The cup is taken away, and the number of the dice is six.

"I'm winning again."

"You're fooling, aren't you?"

"As you can see, I didn't do anything."

"Then why did you guess right twice in a row?"

"It's just luck."

"Hmm...... The second question, let's ask. ”

"Think about it, how old are you?"

“24。”

"Okay, the third game."

This time, Liu Yu picked up the cup and shook it vigorously.

"One!"

"Even."

Unexpectedly, this time Karina chose to guess odd and even numbers.

The cup was opened, and the result was still two, and Karina guessed correctly again.

"Wow, almost!"

Karina just smiled and didn't speak.

"The third question, what kind of person is Han Kun in your mind?"

"Huh? Him? Although it seems to be quite reliable, it is often inexplicably missing. Anyway, maybe I don't know him very well until now...... I always feel that it is difficult to get close to him, but once he and you become friends, the relationship is good...... Something like this? ”

Karina didn't speak, just smiled brighter.

"You've been laughing since the beginning, am I that funny?"

"I'm sorry, I couldn't hold back. I just think you're really simple. ”

"Is there one?"

"I just said that whoever wins can ask the losing person a question, right? But I'm not saying that those who lose must answer, but you seem to take answering other people's questions for granted. ”

"Huh?! So cunning! ”

At this moment, Liu Yu finally reacted, and it turned out that he didn't need to answer Karina's question.

"I can only blame myself for not listening to the rules I said. But the number of points in the third game is the same as I guessed in my heart, it is two. ”

"You guessed it all? How? ”

"For your sak's sake, I'll answer you. As you can see, I didn't do anything, I just came to a conclusion through simple calculations. ”

"Calculations?"

"Yes, just tell the number and angle of your dice by the sound, and the answer is easy to guess. You don't need magic, you just need your brain. ”

"Computing ...... by sound That's scary, right?? ”

Karina shook her head and said, "In order to become an excellent mage, you don't just need to use magic according to the same spell and circuit, but you also need to calculate many factors in your head to make the magic work the best, right?" ”

"Sounds so complicated...... But then again, do you also call this energy magic? It's the first time I've heard this from Han Kun, but you seem to agree with it. ”

"It's not that I agree with it, it's that this energy is like magic, it can produce 'miracles'. For things that are difficult to explain scientifically, it doesn't seem wrong to call this variation of things magic. ”

"Hmm, isn't it natural to use magic to perform magic in a specific way? It's like ice melts when heated, what's so strange about that. ”

"It's not like that, according to a specific method of magic, it can only be said that the most basic can be used magic, but the principle between this is not clear to you, for example, you gave an example, ice will melt when heated, and that is because the ice has reached its melting point. Magic is also because of its principle, which eventually becomes magic. ”

"Seems to be a hard thing to understand."

Liu Yu touched her head, she didn't seem to understand what Kailina said.

"Let me ask you in a different way, do you know what magic is?"

"Isn't magic magic...... What else could it be? ”

"Magic, it's true, it's an energy, but have you ever wondered why this energy is produced in the body, and humans don't produce this energy?"

"I know this! It's because there is a magic circuit in the body! ”

"The mana circuit is just a special kind of circuit, which can store mana, but it is not the main means of generating mana."

"How did that magic come about?"

"If it was so easy to figure out why, it wouldn't be called magic."

"I mean you don't know?"

"I can't say that, it's just that my understanding is not thorough enough to fully understand. For races that can generate magic power, as long as they have a magic circuit in their body, they can naturally generate magic power and store it in the magic circuit, but there are also many races that cannot naturally produce magic power, the most appropriate example is humans. According to my research, the method of generating magic power in most organisms is still the energy substance produced by cells, and magic power is only a form of embodiment, not the initial form of energy. ”

"Hmm...... I don't understand it. ”

"Well, you don't need to know too much about this, anyway, it's good to know more."

"To be honest, you told me so much, I didn't understand a lot of things......"

"I guess in the future, Han Kun will tell you too. I just played a little game with you. ”

"Uh-huh, so what the hell do you have to do to guess the dice so accurately like you? All I know is that this feature can make a lot of money! ”

Karina rubbed her forehead a little speechlessly.

"I can teach you, but only if you learn it, so that I can teach it, right?"

"Well, I'll study hard! So how does this kind of thing do it? ”

"Good. I call this ability 'calculus'. It's also very simple to say, you just need to fully exercise the function of the brain. ”

"Exercising the function of the brain?"

"To put it simply, in a certain amount of time, you can process more information than the average person's brain, and experience the faster use of magic when constructing spells."

"That sounds good."

Karina smiled slightly, her purpose was to let Liu Yu learn this technique.
