What's Wrong with the Witch

　　At this moment, is the magical girl in front of me a demon, or are they a demon?

　　"You guys are hurt too badly, don't worry, you'll be fine soon."

　　The magical girl Sakura raised her wand.

　　No one heard the magic girl in front of him chanting any spells. The great devil Frieza saw the three great devil kings who were struggling and terrified on the ground. The golden light left on the wounds suddenly burst out, like a supernova explosion, instantly killing the three seriously injured people. The Demon King is obliterated.

　　When the dazzling golden light dissipated, the three great demon kings who were still mourning just now seemed to have never existed, and just disappeared out of thin air.

　　"Oops, it's 6:15!"

　　Counting the time, there is a high chance that the magic city will enter the dark night. If the store manager Mu Qiqi does not find her going back, there is a high probability that he will be anxious.

　　Then look at the bull-headed demon god, the sheep-headed demon god and the great demon king Frieza who are facing the enemy.

　　It will take longer for the two demon gods to be eliminated.

　　Most importantly, there is no time to ask where their treasure is.

　　The best solution now is to go back to the magic city first, report at the Magical Girl Cafe, let the manager Mu Qiqi confirm that she is all right, and come out during the night break.

　　In addition, because the magic released this time is somewhat special, the magical girl Sakura felt that the magic power in her body was consumed a little for the first time, and it took a little time to recover.

　　However, before going back, the demon king who wants to invade the earth has to be dealt with.

　　The magical girl Sakura smiled and asked, "Excuse me, who is the Demon King Frieza?"

　　"Friza died just now." Great Demon King Frieza looked serious, "I was killed by you just now."

　　"Is he dead? It's a pity, I really didn't want him to suffer so much." The magical girl Sakura glanced at the time again, "Thank you very much for your answers, I have gone back beforehand and will come back later. "

　　If you have something to go back, will you come back later?

　　The Bull-headed Demon God, the Sheep-headed Demon God, and the Great Demon King Frieza looked at the magical girl Sakura, and their eyes became more and more vigilant.

　　A magic attack just now destroyed the defensive barrier of the temples, and at the same time destroyed the entire temples, killed three big demon kings, severely injured three big demon kings, and at the moment of arrival, they had the opportunity to take the initiative to send them up to be purified. Horror thoughts.

　　Everyone can see clearly that this magic even almost destroyed the whole world.

　　It was such a magical girl, they didn't believe that Sakura would have the kindness to let them go.

　　With a wave of the wand, a teleportation magic circle appeared at the feet of the magical girl Sakura: "By the way, do you have anything else to do?"

　　"No no!"

　　The Bull Demon God said honestly and honestly.

　　The sheep head demon nodded in agreement.

　　Great Demon King Frieza nodded faster.

　　"Actually, I don't have much magic power left, don't you want to do it?"

　　The magical girl Sakura blinked, and the magic teleportation formation under her feet was completed, just waiting to be activated.

　　"Absolutely not. Whoever dares to fight with the cute and cute His Royal Highness is to be my enemy!"

　　The Bull Demon God was the first to pronounce justice!

　　The goat-headed demon god and the great demon king Frieza hurriedly agreed.

　　[If you want to go, let's go quickly! 】

　　They meditate in their hearts.

　　"So, bye!"

　　The magical girl Sakura disappeared and returned to the location of the gate of the world over the ruins of Avon Riel.

　　"Hey, is it about to close?"

　　A few magics were released at will, the world channel was fixed, and the magical girl Sakura returned to the magic city.

　　Because I have to come back to do some finishing work later, I can't let the door of the world close, otherwise I won't know how to come back later.

　　……

　　"Sorry, I'm back late!"

　　Xiao Niao Yu Sakura ran back to the Magical Girl Cafe out of breath, and found that there was a full moon standing in front of the bar in the cafe, and was stunned for a moment.

　　The manager, Mu Qiqi, is not in the cafe. What's going on?

　　You're not going to find her, are you?

　　Picking up the phone, there were several missed calls, all from Mu Qiqi.

　　"Manyue-chan, where's the manager?"

　　With a fluke mentality, Xiao Niao Yu Sakura asked.

　　"Your Highness is out."

　　"..."

　　Doesn't it mean that the dark night is dangerous?

　　Is it really okay for the store manager to go out like this?

　　Yes, call.

　　Xiaoniao Youying called back nervously, hoping to get in touch with Mu Qiqi. As long as she got in touch, even if Mu Qiqi was in danger because of the ringing of the phone, she was confident that she would transmit it immediately.

　　"Sorry, the user you dialed is out of service area. Sorry..."

　　Can't get in touch? !

　　Xiao Niao Yu Sakura looked at the mobile phone that could not be connected, and was very worried.

　　"Manyue-chan, do you know where the store manager went? Her phone is not in the service area..."

　　"Well, you can call later." Man Yue picked up the newly made cake at hand, "Have you eaten dinner? You can eat some cake first, and read a book while you're at it, maybe your Highness will come back later."

　　Man Yue put a small cake in front of Xiao Niao Yu Sakura, and then took a copy of "Arcane Mathematics Research Theory" from the bookshelf and placed it in front of Xiao Niao Yu Sakura.

　　Although I don't know what His Highness Mu Qiqi's arrangement is, since Xiaoniao Youying is back, it would be better for her to stay.

　　"Thank you."

　　Where are you in the mood to eat cake at this time?

　　What if the store manager went out to find her and encountered something weird because he was in a hurry?

　　Xiaoniao Yuying looked down and saw the magic book put down by the full moon, and blinked, how does the book "Arcane Mathematics Research Theory" look like a magic book?

　　"Author, Jonathan Abu."

　　The name seems to have some impressions.

　　Xiao Niao Yu Sakura looked at the magic book, and then looked at the author's name, remembering that when he "visited" the Tower of London library, he saw a large bookshelf full of Jonathan Abu's books.

　　I remember that at that time, Xiaoniao Yuying had just become a magical girl, and very few magics also came from "Urban Legend: Magical Girl in the World", but the magical power in the book "Urban Legend: Magical Girl in the World" is all powerful. It was so big that she almost got into trouble.

　　Therefore, Xiao Niao Yu Sakura tried to learn some orthodox and practical magic.

　　In a dark night, she accidentally rescued a magician who was attacked by a grotesque. She learned from the magician that there are many magic books in the library of the Tower of London of the Magic Association, but if you want to enter, you need to go through the review and approval of the Magic Association. Wait.

　　In short, considering the extremely cumbersome procedures, Kotori Yusakura simply sneaked into the library of the Tower of London to read the magic book.

　　It's just that little bird Yu Sakura never thought that most of the magic books in the Tower of London are related to astronomy, mathematics, physics, chemistry, etc.

　　Mathematics, in particular, turned out to be the foundation of the foundation.

　　Do you need math to learn magic? !

　　Xiaoniao Yuying saw those magic books, and the whole person was not well.

　　That is, from then on, Yusakura Kotori once again remembered the fear of being dominated by mathematics at school.

　　To tell the truth, the mathematical knowledge in these magic books may not even be able to be easily calculated by the graduate students and doctors with their own brains, right?

　　However, in order to prevent her from causing unexpected secondary disasters when using magic, Kotori Yusakura still studied hard.

　　It took a few months to learn a little magic or two before she realized that the truth was not like this.

　　She doesn't need math knowledge to learn some magic...

　　Knowledge The magic book she just started to read, basically every page she opened was an introduction to basic mathematical principles and mathematical knowledge, which made her fall into a misunderstanding.

　　"black tea."

　　With a smile on his face, Man Yue brought another cup of black tea to Xiao Niao Yu Sakura.

　　"Thank you."

　　Xiaoniao Yuying looked at the "Arcane Mathematics Research Theory" on the table, sat down somewhat blankly, and opened it.

　　There is no accident, the beginning is the familiar mathematical formulas, mathematical theories, and related magic principles...

　　Suddenly, a thought flashed through my mind.

　　She looked over the bookshelf, and there were magic books on the bookshelves.

　　And during the day, she remembered that the store manager Mu Qiqi seemed to be reading a magic book seriously.

　　With such a connection, when I first came to the Magical Girl Cafe, many doubts that flashed by were all answered.

　　First of all, the Magical Girl Cafe opened in a very dangerous place like the old city of the magic city. Teacher Kino didn't have any fear on her face, and she dared to go out at night to explain a lot of problems.

　　In other words, Ms. Chino, who she has always admired, Mu Qiqi, the manager of the cafe, can do magic!

　　Secondly, in the library of the Tower of London, the magic books written by Jonathan Abu are basically banned books, and they are locked with a special chain to prevent anyone from taking them or stealing them.

　　However, the store manager Mu Qiqi generously placed such a forbidden magic book on the bookshelf for any customer who wanted to read it.

　　In the end, there will be an elf magician in the cafe, but the store manager Mu Qiqi admits that he is an elf like an ordinary customer, which is enough as one of the evidences that the store manager Mu Qiqi knows magic.

　　Because Xiaoniaoyou Ying can clearly see that the elf magician has a lot of respect for the store manager Mu Qiqi when he leaves!

　　Thinking of this, Xiao Niao Yu Sakura felt a little relieved.

　　When the store manager Mu Qiqi came back, she apologized first, and then tried to return to another world at night to deal with the remaining demon gods and great demon kings.

　　Now that you have encountered it, you must not let it go.

　　After all, every Demon God and Great Demon King has a very rich treasure.
