In the world, the temple house.

"CC Sensei! I want CC teacher! ”

"yes, yes! I want CC teacher too! ”

There was a clear commotion in the temple house, and a few boys were making noise.

Hearing the two little guys coaxing, Mei Hong immediately quit, rolled up her sleeves and pushed open the door of the temple house and rushed in: "Mouth! If the old lady is not there, will you bully Huiyin! See if I don't smash your ass! ”

"Ahh Sister Red! Mei Hong is back. ”

Suddenly, there was a burst of chickens and dogs jumping in the temple house.

Just as Su Han hesitated to push the door in, a loud sound of earth-shattering ghosts and gods came from the temple house.

"Click~"

The sound of the skull exploding made Su Han touch his head.

"Sister Hong! How many times have you said that girls can't be so rough, and what about arithmetic teachers? ”

"In ...... At the door...... Outside ......"

Su Han, who was standing outside the door, didn't need to look to know that a wisp of white soul had slowly floated out of Mei Hong's mouth, and her abrupt voice also showed that she was no longer good.

"Is CC Teacher outside?"

"CC Sensei!"

After the big demon king was defeated, the two bear children became even more lawless, and when they heard Meihong say that the arithmetic teacher was outside the door, they immediately rushed out.

"Huh? It's not a CC teacher. ”

"Who are you? Uncle. ”

"Uncle......

Touching his face, Su Han felt a trace of unhappiness in his heart inexplicably.

"I'm your new math teacher."

"~~~~~~~~~~~~"

The dissatisfied expressions of the two little boys who were still snotty overflowed on their faces, and they shouted loudly: "Don't! I don't want my uncle to teach! I want a beautiful CC teacher to teach me!! ”

"Uncle's voice don't !! I want to listen to the nice voice of the CC teacher!! ”

“#”

With bruises on his head, Su Han resisted the urge to beat these two little ghosts, his face twitched, and he looked at the two little ghosts with a so-called smiling and not smiling expression, and said word by word: "If you are willing, if you are unwilling, hurry up and give me back!" Go! Above! Lesson! ”

Su Han's momentum accumulated from years of teaching monsters was there, and the two little boys were not opponents at all, and they stood in place for a moment, and then ......

"Wow!!!!"

Crying......

"Huh?"

Faced with this situation, Su Han couldn't help but be stunned for a moment, and then, in his field of vision, a spherical object with white hair quickly appeared......

"Click!"

……

……

……

The pain in his forehead still hadn't faded, and the only thing Su Han confirmed was that he had been in absolute shock for a while just now, and the reason should be that he was hit hard by the unknown white-haired ball-like object.

Slowly opened his eyes, and what appeared in front of him was the white-haired ball-shaped object!

"it!"

Reflexively, his hands were crossed in front of his head, but the expected impact did not come.

"That...... I'm so sorry...... I thought you were bullying my students......"

"Ah......" Sitting up with his head covered, looking at the apologetic white hair in front of him, Su Han couldn't get angry if he wanted to.

After all, Mei Hong, who was lying next to her, hadn't woken up yet.

"I'm the lecturer here, I'm really sorry just now, by the way, I want to ask, why didn't Teacher CC come, did I do anything to make her angry?"

"Uh, hello, my name is Su Han, as for CC, Mr. Kamibai Ze, do you remember what she said when she promised you at the beginning?"

"Well, I remember it was 'I only teach ...... for two days'" Before the words were finished, Huiyin herself was stunned: "Two days ......"

"So she's ...... now"

"That's right...... But that's a tough one...... In the past two days, CC teacher she only taught everyone to know numbers, and the calculation method has not been taught, and my algorithm is more complicated than CC teacher's method, and the children are not willing to learn, what should I do......"

"So I'm here, as long as they have the basic computing power for life, right?"

"Except for Master Wang, who wants his children to learn geometry again so that they can inherit his architectural career, the other children only need to know how to add, subtract, multiply and divide, but ......"

Huiyin's words were not finished, but the slight worry in her eyes still revealed a kind of are you okay? This means.

Su Han didn't answer in any language, he immediately walked on the blackboard, Taylor expanded, partial derivatives, differentiation, integration, functions, limits, arrays, and wrote a blackboard at once, after completing the last stroke, Su Han shook the chalk in a chic manner, turned around, and slapped the blackboard fiercely, shaking the white powder on it and falling down.

"Still have questions?"

Seeing that the eyes of everyone below, including Huiyin, completely turned into mosquito coils, Su Han nodded with great satisfaction, the mathematical formula has such a huge power, even if you can't understand it, but as long as you look at it, the combination of these numbers and symbols can make you confused and delirious!

That's right, there is magic in mathematical formulas.

"Good...... What a deep magic pattern......"

"No, it's not a magic pattern, it's just math."

Su Han's loud words made the faces of the students present suddenly pale, originally the CC teacher taught only ten very simple numbers two days ago, which gave them the illusion that mathematics is not difficult, but I didn't expect it to be such a crazy thing after that!

The children's faces all looked like they had seen hell.

"This ...... These are all ...... What do you need for daily use......"

Even Huiyin's teeth began to tremble, she knew that Su Han would not come here to teach students for a long time, so she planned to study next to him when he was teaching, and continue to teach students later, now......

Otherwise, it would be better to teach ancient arithmetic from the beginning in the future......

"No, you don't."

As he spoke, Su Han wiped off the ghost drawing talisman on the blackboard.

"Now, then, stretch out your hands, and we'll learn addition and subtraction."

Two minutes later, in the minds of all the children, Su Han was as beautiful as an angel.

It's nice that you don't have to learn those ghost talismans......

————————————————— Dividing Line——————————————————

Just when Su Han was happily becoming a teacher, some changes were quietly appearing on the side of Boli Shrine.

“……”

Under the cherry blossom tree, the man-eating monster couldn't help but feel irritated when he looked at the smiling little Reimu in front of him.

"So, what the hell are you trying to do?"

These were the first words she spoke to Reimu.

Even after being murdered by the man-eating monster, Xiao Lingmeng's expression did not change at all, and he still smiled.

"Who are you?"

“……”

"Na~ Who are you? My name is Reimu. ”

Looking at the innocent and immaculate face, without the slightest malice, the man-eating monster was stunned for a moment and looked away.

"Lumia ......"
