I, the Male Protagonist of the X Series

The two monsters frowned and looked at Rin at the same time. Zi stopped temporarily because of her relationship with Rin, and Yakumo Lan stopped because she was really kind.

"Fox." Rin closed the phone, the corners of his mouth curled up, and with a determined look, he took a few steps closer to Lan, "Don't you like mathematics? Coincidentally, I am also good at mathematics. Fighting and killing are boring, how about that?" , let's have a math showdown!"

"Mathematics... showdown?"

Yakumolan read it a few times silently, her eyes brightened, and then hesitated again: "No... I am determined to die... How can I be tempted by cricket mathematics... But, I really want... I really want to wow! "

"In this way, let's each come up with an arithmetic problem. Whoever can solve it will be considered the winner. If you win, fox, then Sister Zi and I will never say anything about what happened today. You can leave if you want. If you lose , just obediently be sister Zi's shikigami!"

Yakumo Zi's eyebrows twitched slightly, seeing Rin who had a good chance of winning, he relaxed and waved his fan to watch a good show.

Yakumolan's face was full of confusion. Thinking about it carefully, with her intelligence being no weaker than anyone else in the entire monster population, plus her hundreds of years of research on mathematics, how could she lose to a fifteen or sixteen year old? Human child? !

"I understand."

Is this boy going to let me go on purpose...

Suspicious Yakumo Lan finally decided to accept the bet, then carefully adjusted her clothes, and bowed slightly to Rin like the most upright scholar.

"Then, after all, you are a weak human being, so it's up to you to come up with the question first."

Rin... I feel very guilty. This feeling is like digging a hole in front of my friend, but I still have to watch the other party happily jump into it.

The promised nine-tailed strategist is the best among all the heroes... Forget it, let's teach Yakumolan a good lesson today.

"In this way, I have a lot of copper coins to buy rice. I used half of it plus three coins for the first time, and used the remaining half plus three coins for the second time I went to buy rice. Take half of the money left over from the second time plus three qian to buy rice, and go back and forth a total of five times to just use up all the copper coins, ask, how much money did I take in total?"

Yakumolan, who was obsessed with math problems as soon as she heard them, quickly squatted down and drew on the ground with her fingers, biting the other finger from time to time, her brows furrowed.

Yakumo Zi on the side also tapped her fan thoughtfully, as if muttering to herself, as if she was also calculating.

Rin reckoned that it would take a lot of cumbersome calculations to solve the senior three problems with the current ancient arithmetic level. It is true that Yakumo Lan could solve it, but it would definitely not be solved in a short time, so he stood there quietly and waited.

They stood unscrupulously not far from the Daming Mansion. The door was opened after a while, and the onmyoji with a tall hat got his head out from the crack of the door, but then saw Yakumo Lan tilting up and swinging from side to side. Tail, the whole body was shocked and the face was full of horror and retracted.

Ten minutes later, Yakumo Lan, who was still scribbling back and forth on the ground, frowned more and more. Rin saw that the time was almost up, and smiled slightly: "So... how long are you going to delay, fox?"

"I……"

Originally, she had some thoughts, but was abruptly interrupted, Yakumolan held back her stomach full of anger, opened her mouth for a long time, and sighed dejectedly: "Well, in fact, I only need a few hours to untie it..."

Some mournful foxes regained their spirits not long after, and after thinking for a while that it would be their turn to write a question and still have a chance to tie, they hurriedly said, "Now it's my turn, I'll test you, there are three fox demons going to stay, one Thirty cents late, each person collected ten cents and paid the bill and left. The store manager said that today’s discount is only 25 cents, and took out five cents to ask the servant to return them. The servant secretly hid two cents, and then , and distributed the remaining three coins to those three people, one for each. In this way, each person paid ten coins at the beginning, and now one coin is returned, that is, each person only spent nine coins. The three foxes The demon spent a total of 27 coins plus the two coins hidden by the boy, only 29 coins, where did the other money go???"

Chapter 250 Master Zi, please rest assured to put Rin on me

Yakumo Lan now has the heart to sacrifice the entire fox clan to death, and she, a majestic master of arithmetic, easily lost to a cricket, a human teenager.

In fact, Rin was happy in his heart silently. It was not good for Yakumo Lan to ask a question, but it happened to be an elementary school Mathematical Olympiad question. I also blamed that the ancient arithmetic in District 11 was inherited from outsiders and did not develop by itself, which led to Lan Yin The proud mathematics is not really worth mentioning.

Yakumo Zi, who had watched a good show, felt stable, and with a sense of relief after seeing her husband Jackie Chan, she silently cast a ecstatic look at Rin, but adjusted to be serious, she took a step forward, and walked to the right OTR Beside Yakumo Lan, who was in a state, raised her face with a folding fan.

"Well, not bad, the appearance and strength are not bad, although it is a bit stupid, it can barely become our initial shikigami."

As a senior member of SVIP of the Appearance Association, Zi Yagumo, whether she is making friends or accepting pets, the first thing she likes is to have an appearance that she thinks can be seen well.

Of course, in Yakumo Zi's view, there is no one more beautiful than my old lady in the whole world anyway.

"I understand, youkai sage Yakumo Zi-sama."

Yakumolan collected her mood, rearranged her clothes, and sat up straight: "I am willing to become a shikigami, please conclude a contract."

She was so well-behaved and obedient, which added a lot of favor to Zixin. She nodded, and tapped the fox's eyebrows with her index finger. The complex transparent rune marks began to rotate and spread around the fingertips, and finally converged into a small The imprint of Yakumo flashed in the middle of Yakumo Lan's forehead, and then disappeared.

"It's done, then... Now that it has become our shikigami, the previous name can no longer be used, emmmmmmm, it should still be called Yakumolan."

"Understood, Master Zi."

Seeing the completion of the ceremony, Yakumolan put her hands in her sleeves and stood silently behind Zi. After thinking about it, Rin felt that she couldn't easily let go of this thigh. She rummaged through her phone, her eyes lit up, and she coughed lightly. Go to Lan's side.

At this time, Lan, who had been bullied, rejected the young man from the bottom of her heart, and when she saw him approaching, she turned her face slightly to express her dissatisfaction.

"Then, Lan, I'm sorry before, as an apology and a meeting gift, I specially prepared some items for you, I hope you like it."

Rin, who is already a social person, understands that to deal with girls, he only needs to give suitable gifts to quickly establish a good relationship. This is why he maintains a stable relationship with the girls of Gensokyo in the future, even the girls who are forbidden. friendship value.

I took out the complete math question bank from elementary school to high school plus textbooks that I prepared for my younger sisters Sakura and Xiaoxue in the mobile phone, and placed bundles between myself and Lan, and finally accumulated more than two Yakumo Lan A hill so tall.

"These are all arithmetic textbooks and question banks. It doesn't matter if you don't know the symbols and words on them. Just finish reading the enlightenment textbooks and Chinese documents next to it. Uh...it looks like a lot, but it's actually okay. I haven't When I was in school, it was more than a tenth, and this is the first gift I gave you."

Silently apologized to her sister in her heart, and determined to make up ten times to repay it after going back, Rin looked at Yakumo Lan with full expectation.

With Zi's face all over the place and her hands trembling, Yakumo Lan glanced at Zi and found that she didn't object, so she curiously picked up a junior high school math book.

I don't know why, but when she saw the curved symbols on the cover, and the geometric figures one by one, even though she understood it, her heart seemed to be hit. The feeling that went straight into the heart made her heart beat faster, as if she met To the love of my life.

Even... She opened the book, indulging in this pile of incomprehensible symbols.

Seeing Yakumo Lan seemed quite satisfied, Rin secretly heaved a sigh of relief, and at the same time felt that math geniuses were really extraordinary, those world-renowned math geniuses, as expected, were like Yakumo Lan when they were enlightened by these incomprehensible ones The earthworm completely hooked the heart and soul, and then began to indulge in solving problems, right?

Then, Rin took out the second gift he had prepared.

Although it is a big gift, it is actually the last time in Kamakura Castle because of gluttony, I accidentally bought all the tofu from the fried tofu stall, but the eyes were big and the belly was small, so I didn’t eat a few pieces and stuffed them all. phone space.

Because there is no air and no time in the mobile phone space, the oiled paper bag is still hot after taking it out and opening it, and the tangy fragrance comes out, which immediately draws Yakumo Lan's attention away from the book.

"This... this is... fried tofu!"

The two golden eyes were full of surprises, and before Rin could speak, she was already looking at the oiled paper bag in Rin's hand with great anticipation: "Is it possible? Is it really possible?"
