"Thank you for your kindness, but there are still many things in the fish mansion. It's not convenient for the villain to stay for a long time, so the villain will take his leave first!"

He Ren said quickly.

"Uh-huh!"

Xu Da looked up at He Ren, then nodded repeatedly.

Wait until He Ren leaves.

Xu Da moved the chopsticks faster.

Xu Huizu, who was burying his head on the side, felt anxious.

Then, he opened his mouth wide and started eating quickly.

Fortunately, He Ren gave him a lot of fish dishes, with a full eight fish dishes.

Therefore, although the meal was very urgent.

However, my stomach was round and full of food.

Several people's faces were comfortable.

Only Xu Huizu kept muttering and turned his head, and never thought about Xu Da.

"Haha, Zuer, what's wrong with you? You've been clamoring every day and wanting your father? Why do you look so unhappy when you come back today?"

Seeing the eldest son look like this, Xie Cui'e asked in confusion.

"Father is bad!"

Xu Huizu pouted, remembering what happened just now, and was still a little angry.

"Well, your father just got home, where did it break down?"

Xie Cui'e was stunned and looked at her apologetically. Xu Da, who was also confused, quickly asked curiously.

"There are eight fish dishes on the table. My mother and I only ate three fish dishes. My father ate all the remaining five dishes, leaving no bite behind!"

As he said that, Xu Huizu felt even more aggrieved.

He has been waiting for these fish dishes for more than a month.

Unexpectedly, after finally being able to eat it again, my father who had just returned had eaten so much.

"Haha, little greedy ghost, these fish dishes were originally sent by Xiao Zhenren of the Mermaid Mansion to your father. If you want to eat them, you can ask them to give them!"

Xie Cui'e was stunned for a moment, then said with a smile.

On the side, Xu Da also looked funny, "Zu'er, if you still want to eat fish, tomorrow, we will take you to the fish mansion and eat fish again!"

"Thank you, my father!"

Upon hearing this, Xu Huizu looked at Xu Da with a smile on his face and said excitedly.

"But we're very curious, have you learned arithmetic?"

"arithmetic?"

I heard that my father was going to take him to the fish mansion to eat fish tomorrow. The gap that had not been seen for such a long time disappeared.

Xu Huizu stared at Xu Da with his eyes, a little confused.

Seeing this, Xu Da laughed.

How old is this kid in his family? Why do you expect him to learn arithmetic?

Even those seven or eight-year-old boys may not be able to learn arithmetic!

"Joy, that's the addition, subtraction, multiplication and division of numbers!"

On the side, Xie Cui'e's expression moved and she quickly said with joy.

"Numbers, subtractions, multiplications, and divisions?"

Now, Xu Da looked puzzled again.

The numbers seem to be Arabic numerals invented by Zi'an, with some strange shapes.

But what is addition, subtraction, multiplication and division?

"Zoer, what did Mr. teach you? Show it to your father?"

Xie Cui'e encouraged.

"Yes, mother!" Xu Huizu glanced at his mother, not knowing what these simple numbers were to show.

However, looking at Xu Da's confused eyes, an impulse surged in Xu Huizu's mind, and he quickly opened his mouth and said, "One plus one equals one, one plus two equals three, one plus three equals four... One gets one, one gets two, one three gets three... Three three gets nine, three forty-two..."

After he finished caring, Xu Huizu looked up and saw his father's big mouth and shocked face.

Suddenly, a slight sensation in the cerebral.

"Aren't these arithmetic?"

After a while, Xu Da realized and looked at his eldest son, who was only four years old, with joy on his face.

I still can’t believe that my kid is so young that he can already do arithmetic!

"Zoer, if the fish mansion shopkeeper just brought eight plates of fish dishes, we had four plates, and your mother had two plates, how many plates were left?" Xu Da asked again.

"Two plates!"

Xu Huizu's mouth sagged and said angrily.

Bad father gave him some delicious fish dishes.

However, Xu Da was unaware of anything. After hearing the answer, his eyes lit up and he continued to ask: "If Manager He brought eight plates of fish dishes again, how many fish dishes did Manager He deliver to our mansion tonight?"

"Twenty-four ways!"

Xu Huizu replied directly.

"If I had five plates of aquarius for my father, how many plates of aquarius for my father tonight?"

Xu Da laughed loudly, as if he had found some fun toys, and continued to ask.

However, Xu Huizu was even more angry when he heard this, and said with a grievance: "Fourteen plates!"

"good!"

Xu Da was overjoyed, "I didn't expect that my son was a child prodigy. He could have such complex arithmetic at such a young age!"

"What do you want to eat tomorrow? I'll take you to eat!"

"Thank you, my father, I want to eat fish dishes from Yu Mansion!"

Xu Huizu quickly looked happy.

"Okay!" Xu Da.

"master."

Xie Cui'e hesitated for a moment and said slowly.

"Um?"

Seeing this, Xu Da was stunned.

Then, he asked with some confusion: "Madam, what's wrong?"

"Master, in the entire Nanjing city, all children with some financial resources have learned arithmetic from one to ten. Even many children have passed the enlightenment and have learned hundreds of words!"

Xie Cui'e said.

"What?"

Xu Da was shocked.

He glanced at Xu Huizu in his arms, then hurriedly looked at Xie Cui'e and asked, "Madam, what's going on?"

"Master, the little Wudang Zhenren created a letter that can help many illiterate people to enlighten and make people quickly learn to read. In addition, this little Wudang Zhenren also created a number from zero to ten. This number has a formula of addition, subtraction, multiplication and division, which is the formula that Zuer just recited. If you learn the formula, you will soon learn arithmetic!..."

Xie Cui'e said.

"Is there such a magical object?"

After hearing this, Xu Da's face was shocked.

Finally, Xie Cui'e gave Xu Da a concentrated explanation of the Thousand Character Enlightenment text, dictionary, and a set of arithmetic booklets from zero to ten. After Xu Da was finally told by a shocked look, she slowly accepted it.

"So, Tang He and the boys in Chang Yuchun's family have also learned this?"

"The master is right!" Xie Cui'e.

"I didn't expect that Zi'an would be so talented!"

Xu Da sighed deeply, looking inexplicable.

"master?"

Xie Cui'e said in confusion.

"Nothing happens."

Xu Da waved his hand.
