Because Kong Fang was still busy with matters in the Internal Affairs Hall in the morning, Mingdai arranged her math class to the afternoon.

But even so, Kong Fang was still almost half a cup of tea late.

"Elder Tang, I'm sorry, I'm late!" Before anyone could be seen, his shout came from outside the yard.

Ming Dai was originally explaining the Sword Sect's mental method to Xiao Douding. She paused for a moment after hearing the words, and then she saw him running in, panting, and she didn't even have time to wipe off the sweat.

"I'm sorry, I'm really sorry."

Afraid that Mingdai would be angry, he apologized and explained: "Because of what happened yesterday, early this morning, the sect sent people down the mountain to cooperate with Linxian Town for a strict investigation, and even the Internal Affairs Department became busy."

"I originally thought I would be able to leave on time, but I didn't expect that another urgent job came from the nearby stall. I didn't have time to deliver the letter to the peak. I'm really embarrassed..."

When this matter was brought up, Kong Fang was so embarrassed that he wanted to find a crack in the ground to tuck himself in.

Yesterday, he finally asked Elder Tang to agree to teach him, but he was late for class on the first day...

"It's okay. Just drink some water and rest first. Don't worry." Although Kong Fang is not very bright at times, he is still very reliable in doing things.

Seeing that he hadn't come over before, Ming Dai guessed that he was probably stuck by work, so she was not in a hurry to take math class.

"It's easy to catch cold if you sweat in spring. You wipe the sweat on your face first, and I'll get a teaching aid. We'll start class in half a quarter of an hour."

"Thank you, elder!"

Kong Fang breathed a sigh of relief, quickly found a place to sit down, then raised his sleeves and wiped his sweat without caring.

As a result, when he was halfway through wiping, he noticed from the corner of his eye that not far away there was a little baby with two buns on his head, staring at him with a smile.

Kong Fang was stunned for a moment.

Sister, who are you?

Just when this idea came to his mind, he heard the child smile and say to him: "Senior Brother Yuanyuan, you are too slow."

Kong Fang:???

Is this voice Ah Ruan?

There was a buzz in Kong Fang's mind, as if he had been struck by lightning. It took him a long time to realize that Little Douding seemed to be a girl...

But this difference is too big, right?!

Kong, who had just sat down, stood up from the chair with a "swish" sound.

Obviously when we met yesterday, he was still a "little beggar" covered in patches and rolling in the mud. How come he has turned into a beautiful little girl today?

"you……"

He opened his mouth wide in surprise, but before he finished speaking, Xiao Douding on the other end took the initiative to ask: "I heard from my uncle that starting from today, senior brother Yuanyuan will also have math classes with Ah Ruan?"

"Well, that's what I'm saying for now..."

"That's great!" Xiao Douding suddenly clapped her hands happily, leaving Kong Fang stunned for a moment, wondering why she was so happy all of a sudden.

"What's great?" he asked funny, "because you finally have someone to accompany you to class?"

Apart from this reason, Kong Fang could not think of any other reason.

After all, there are only five disciples on the entire Qingshan Peak. As a result, three of them are currently in retreat. The other one has gone down the mountain and returned to his hometown. I don’t know when he will come back. In the end, she is the only child left. It is inevitable that she will feel a little lonely.

.

It's a pity that he is also busy at ordinary times, otherwise he would still be able to come over and help Elder Tang take care of the baby.

Kong Fang was lost in thought, but Little Douding shook his head when he heard this, glanced at him enigmatically, and said in a sweet voice: "You guessed wrong. This can only be one of the reasons."

Kong Fang: “Are there other reasons?”

"Of course!"

Xiao Douding nodded and said seriously: "I heard from my uncle that those who go to school early will be called seniors. Is it true?"

"Senior, senior?"

"Senior brother, senior sister, and uncle said this, but I don't quite understand."

"Senior brother and senior sister." Kong Fang usually deals with internal affairs within the sect and is very familiar with this aspect. He subconsciously introduced:

"Theoretically, this is true, but the seniority algorithm between peaks and between inner and outer gates is somewhat different..."

Halfway through his words, he suddenly remembered that the person sitting in front of him was just a four-year-old girl, not those half-grown men in the Internal Affairs Hall who were causing trouble everywhere when they were just recruited.

The most important thing is that Ah Ruan is an inner disciple. Even if she grows up and understands it in the future, she will not need this knowledge.

Then Kong Fang suddenly fell silent.

"Senior Brother Yuanyuan?"

"Yeah...it's okay." Kong Fang quickly recovered and replied concisely, "You're right, it's almost like that."

Afraid of being chased by Little Douding, he quickly changed the subject, "But why are you asking?"

This has nothing to do with him coming to Qingshan Peak to attend classes, right?

"Of course it does matter!" Xiao Douding said with a smile, and Kong Fang realized that he had asked the second half of the sentence unknowingly.

At the same time, Xiao Douding raised his little hand in front of him: "Although senior brother Yuanyuan joined the Sword Sect earlier than Ah Ruan, if we count the courses at Qingfeng Mountain, senior brother actually entered the school before Ah Ruan.

It will be several days late."

Kong Fang: "So?"

Xiaodouding: "So, A Ruan will also be a senior sister from now on."

After saying that, she patted Kong Fang's shoulder with great assurance and said, "Junior brother Yuanyuan, don't be afraid. Mathematics is not difficult to learn. If there is anything you don't know, just tell senior sister and she will teach you!"

Kong Fang: “…”

Mingdai, who happened to return: "..."

She called him back dumbfounded: "Aruan, what are you talking about? That's your senior brother, don't yell."

Xiao Douding didn't understand: "But that's what you said before, uncle, and junior brother Yuanyuan also agreed."

Kong Fang: No, I did not agree.

However, he was already seventeen or eighteen years old, and he had long passed the age of caring about these things. When he saw Ah Ruan acting like a young adult, he started to laugh.

He said: "It's okay, Elder Tang. She can be called whatever she wants. I don't mind."

Since Kong Fang himself said so, Ming Dai couldn't say anything more. Seeing that the time was almost up, she calmly shouted "Class".

The whole family sat upright for a moment.

Ming Dai first set her sights on the big one.

"Yesterday I asked you to go back and familiarize yourself with those Arabic numerals and the most basic arithmetic symbols. How are you getting familiar with them?"

For some reason, Kong Fang always felt that after shouting "Class", Elder Tang seemed to be a different person, and his aura became much stronger.

Obviously she didn't do anything, but the moment she looked over, it felt like there was a sword against her back, which made people think not to take it seriously.

Kong Fang said honestly: "I have memorized it all." For this reason, he secretly practiced it many times in the morning.

So Mingdai randomly recited a few calculations and dictated them to him. Kong Fang raised his pen with a sullen face, as if facing a formidable enemy.

And just as he picked up the pen, the "little senior sister" next to him also became worried, but she knew that she couldn't disturb him right now, so she lay on the table and watched quietly.

In the end, except for the strokes of some numbers that looked a little crooked, Kong Fang's dictation accuracy rate reached almost 100%.

Mingdai was quite satisfied.

Although these numbers and operation symbols are not very complicated, it is not easy for people who have never been exposed to this mathematical language to memorize them all in just one night.

It can be seen that he has put real effort into it.

Mingdai: "It will be easier once I write it all down."

Originally, she thought that if Kong Fang didn't remember it, she would have to spend half of the review class first, but now she didn't have to worry at all.

As for those basic calculation rules, Mingdai didn't have to worry about it. After all, Kong Fang had worked in the Internal Affairs Hall for several years, so he couldn't even memorize the multiplication tables and the like.

Because of this, the moment Ming Dai took out the teaching aids he was going to use today, he was stunned.

"abacus?"

Ming Dai nodded: "Yes, it is an abacus, but it is not a simple abacus."

Kong Fang was a little confused.

What does it mean? Isn’t an abacus just an abacus? There are so many people in the House of Internal Affairs, but no one has discovered any mystery?

Ming Dai smiled and did not rush to explain. Instead, she asked: "Kong Fang, do you usually use abacus a lot?"

Kong Fang nodded without thinking.

Not only that, it’s simply inseparable!

All kinds of data in the House of Internal Affairs are always messy and messy. When the salaries are paid to each peak at the end of the month, there is a crackling sound in the whole room, day and night.

At its worst, many people had cramps in their hands when trying to use the abacus, and even several abacuses were broken.

But what does this have to do with today’s lesson?
