My Wife is Unbeatable in the Whole World, Touch Me If You Dare!-Chapter 76 - Getting Revenge for Wife [5700 words]

These four elders, Song Jiaren knew them all.

They had all once taught her mathematics.

In fact, it had only been Mr. Chen teaching her in the beginning, but later on, Mr. Chen said she had no talent for mathematics and suggested that her family find someone else more capable.

The other three, in an attempt to prove they were more skilled than Mr. Chen, took the initiative to teach her without even accepting any payment...

However, they eventually all proved unsuccessful.

After being told by the four most esteemed mathematics experts in Daxia that she lacked mathematical talent, she had devoted herself to the Martial Path and stopped studying mathematics altogether.

That was until she met him... only then did she realize that mathematics was not actually that hard.

For Li Nuo, explaining to one elder was the same as explaining to four.

It must be said that these three elders were very quick learners, just like Mr. Chen, understanding with just a hint. Teaching them was simply too easy.

After about half an hour, Li Nuo didn't plan to continue any further.

Firstly, he didn't want to waste more time, and secondly, the more he explained, the less they would be able to digest.

Li Nuo bowed to the four of them and said, "I have other matters to tend to this evening. I will discuss further with you gentlemen some other day."

"We are of modest ability and are not worthy of discussing such matters."

"We thank Mr. Li for his instruction."

"We will not disturb you further today, and we hope to seek your guidance again another day."

...

These four elders were indeed more humble than the next, bowing to Li Nuo in respect of a disciple before leaving together.

Song Jiaren stood by the door, and as the four men walked past her, she too nodded slightly: "Sirs."

As the four elders looked at Song Jiaren, their minds were filled with relatively old memories.

"Isn't this the little girl from the Song Family?"

"She's grown up so much in the blink of an eye."

"Indeed, the last time we saw her was over ten years ago..."

"It's because we are getting old..."

After the four elders left, Li Nuo stepped forward and asked, "Wife, you know them?"

Song Jiaren lowered her head and said, "They used to teach me mathematics."

Li Nuo was taken aback: "All of them taught you?"

Song Jiaren nodded and said, "They all said I didn't have much talent for mathematics, and then they stopped teaching me..."

Not knowing how to teach herself, Li Nuo looked displeased in the direction the four elders had left, then turned to comfort her, "What do those old men know about mathematics? Don't take their words to heart. If you want to learn mathematics, I can teach you. After you've learned it, even those old men will have to call you 'Sir'..."

It wasn't that Li Nuo was making empty promises; although his wife indeed didn't possess a great talent in the field, as long as she could master high school level math, teaching those old men wouldn't be a problem at all.

Functions, sequences, conic sections, spatial geometry, probability and statistics... Just throwing out one of these would open up a new field in Daxia's mathematics, enough to occupy those elders for the rest of their lives.

To use these would be picking on them; even a slightly harder elementary school math Olympiad problem would be challenging for them.

Li Nuo finally understood why his wife had been disinterested in studying since her childhood.

If he had been similarly discouraged in his confidence as a child, he wouldn't have cherished learning either.

For a child, a good introductory teacher is very important.

These old men understood mathematics, but they simply couldn't teach.

If they had any outstanding mathematics students, it wasn't because they taught well but because the students themselves were naturally talented in mathematics.

In order to help his wife regain her confidence, Li Nuo picked an elementary school-level math Olympiad problem to teach her that night after washing up before bed.

It was a modern application problem, but with a change of description, it could be transformed into an ancient military problem similar to the previous "General Drinking Horse" or "Hu Bugui."

The problem was very short, only a few lines long, but the solution method was quite tricky.

Though it was just an elementary school question, it was known to stump many high school and college students.

Even though Li Nuo stripped away all the problem's distractions, going straight to the point and breaking it down from complex to simple, it still took nearly half an hour to make her thoroughly understand it.

His throat was dry from explaining so much, so he picked up the teapot and drank heartily until his thirst was quenched.

Setting down the teapot, he said to Song Jiaren, "That problem was simple, right? Even you, with no mathematical talent, understood it. Tomorrow, those old men will come again, and you can take this problem to them and see if they have any talent..."

In the beginning, Song Jiaren felt the problem was completely baffling, but after Li Nuo's explanation, she found it quite simple.

The gentlemen were considered the leading mathematicians in Daxia; such a problem shouldn't be too difficult for them...

While she was thinking this, Li Nuo had already adjusted the pillows on the bed.

For some reason, he had woken up with a stiff neck yesterday, and it still hurt.

This body really was pitifully fragile, getting a crick in the neck from sleep. With a physique like his wife's, it was something he could only envy.

Martial Artists were like warriors, with physical strength that increased as their prowess did.

Legalism was more akin to Mages; even at High Realm, they couldn't change the fact that they were fragile.

With his wife by his side, Li Nuo always slept soundly.

Upon waking, washing up, and having breakfast, with nothing else to do, he went to the County Magistrate's Office for a visit and tried his hand at resolving a few disputes among the common folk, but still didn't feel any increase in his lifespan.

It seemed that when he returned in the evening, he would need to pay more attention to Song Yu.

At this time, at the Song Residence.

The four white-haired elders walked side by side into the small courtyard they had visited the day before.

Seeing Song Jiaren practicing swordplay in the courtyard, Old Man Lu nodded and said, "As I said before, she is not suited for mathematics. Now it seems that I had foresight, otherwise, we would have wasted a fine Martial Path prospect..."
