Guo Yan took Liu Meng and turned to leave, but when he just walked to the door, he suddenly stopped.

"Liu Meng, you wait at the door."

After giving a command, Guo Yan turned back and came to Zhang Xiaochi's side and whispered.

"Brother Zhang, there has been a major news in Kyoto Prefecture in the past two days, do you know?"

"What's the matter?"

Zhang Xiaochi vaguely guessed what he was going to say, but he didn't say it explicitly, and asked pretending not to know.

"Miss Ling'er ran away from home again!"

"The Zhao family's missing person notice is posted all over Kyoto Prefecture, and because the reward is huge, many people have joined the search for Miss Ling'er."

"I knew about Ling'er running away from home that day, this girl is used to being wild, I know her, and it's because Ling'er ran away from home and came to Qingwa Town, otherwise, I wouldn't know her."

"Miss Ling'er is so good-looking, isn't it dangerous for the little girl's family to be alone outside?"

Guo Yan said worriedly.

"This is not something you and I can worry about, she was able to go from Kyoto Prefecture to Qingwa Town alone, which is enough to prove that Ling'er has the ability to live independently."

"Brother Zhang, aren't you really worried?"

"It's useless to worry, I've looked for it, but I can't find it."

"Think about it, the Zhao family's energy is so big, they need to mobilize everyone to find someone, can they be found just by their personal ability?"

Zhang Xiaochi asked rhetorically.

"As far as I know about Ling'er, she won't run away from home for no reason, this time she must have encountered something that she can't accept."

"Therefore, it is not necessarily a bad thing for Ling'er to run away from home."

Guo Yan nodded, he lived in Kyoto Mansion all the year round, and naturally knew that Chen Huizu of Huaqing Mansion had been pursuing Zhao Ling'er, and at that time, the Zhao family intended to let the two families marry, but Zhao Ling'er did not agree, and then ran away from home.

"I used to think that the children of powerful families like them had no troubles, but now it seems that the troubles are even greater than those of us ordinary people!"

"Yes, I don't even have the right to choose the other half of my life!"

Zhang Xiaochi also sighed, and the two chatted for a while, and then Guo Yan left the restaurant with Liu Meng.

After closing the door and coming to the backyard, Zhao Linger stopped him and asked who he was talking to outside, and Zhang Xiaochi had nothing to hide about it, and relayed what Guo Yan said to him.

As soon as she heard that it was Guo Yan, Zhao Linger suddenly lost interest.

"Brother Zhang, I'm still going to stay with you for a long time, can you give me a way to pass the time?"

Zhao Linger changed the topic and asked.

"Husband, what Ling'er said is right, if she stays in the backyard all the time, it will indeed be very boring after a long time."

"It's best to find something for Ling'er to pass the time."

Lin Xiaoxi followed the suggestion.

Zhang Xiaochi nodded slightly, Ling'er, this girl is indeed idle, thought about it, and said slowly.

"Otherwise, I'll teach you how to multiply the ninety-nine table."

As soon as these words came out, Lin Xiaoxi and Zhao Ling'er were immediately confused.

"Ninety-nine multiplication table?"

"What is this?"

The two asked in unison.

Zhang Xiaochi smiled, he didn't answer immediately, took a pair of chopsticks from the table, and counted four chopsticks from it.

"How many chopsticks are there?"

"Four chopsticks!"

Zhao Linger replied.

Zhang Xiaochi didn't speak, put the four chopsticks together, and then piled each four together, a full pile of ten.

"How many chopsticks are there now?"

Zhang Xiaochi asked.

"I'll do the math."

Lin Xiaoxi and Zhao Ling'er picked up the chopsticks one by one and counted them, and after a while, they said slowly.

"It's forty chopsticks in total."

Zhang Xiaochi still didn't speak, four chopsticks in a pile, and so put six more piles.

"How many now?"

"Wait, I'll do the math."

Lin Xiaoxi was about to count one by one, but was stopped by Zhang Xiaochi.

"Husband?"

Lin Xiaoxi looked at him with a puzzled expression, not understanding why she was stopped.

"Are you going to count them one by one?"

Zhang Xiaochi asked.

"yes, don't they all do?"

Zhao Linger asked rhetorically.

"There are four of these chopsticks, how many are there?"

Zhang Xiaochi asked with a smile.

"Wait until I count them."

"Sixteen piles in total."

"Each pile is four, a total of sixteen piles, how many chopsticks are there in total?"

Zhang Xiaochi asked.

"This ......"

Zhao Ling'er and Lin Xiaoxi showed hesitation, the two glanced at each other, and then smiled awkwardly.

"Sixty-four in all."

Zhang Xiaochi replied, and reminded the two to check if it was correct.

After inspection, it turned out that it was really sixty-four, and the eyes of the two looking at Zhang Xiaochi were immediately different.

"Husband, how did you do it?"

Lin Xiaoxi asked in surprise and joy.

"Brother Zhang, you put the chopsticks, did you silently calculate them when you put them?"

Zhao Ling'er asked curiously.

"In this way, you can put the chopsticks, as long as they are a pile of four."

Zhang Xiaochi reminded with a smile.

Just do it, Zhao Linger grabbed a handful of chopsticks, and according to the requirements, a pile of four began to be placed, and it didn't take long for Zhao Linger to finish the placement work.

"Brother Zhang, now let's calculate how many there are."

Zhao Linger clasped her hands to her chest and said proudly.

"There are twenty-six piles in total, so there are one hundred and four chopsticks."

Zhang Xiaochi just glanced at it briefly, and then said the standard answer.

"So fast!"

"Brother Zhang, you won't be blind, will you?"

Just when Zhao Ling'er was questioning, next to him, Lin Xiaoxi began to count, and after a few minutes, Lin Xiaoxi finished counting.

"Sister Xiaoxi, is it one hundred and four?"

Zhao Ling'er looked at her expectantly, Lin Xiaoxiqiao's face was full of shock, and she nodded slightly.

"One hundred and four, indeed."

"Husband, how did you do that?"

Lin Xiaoxi asked curiously.

"It's simple, twenty-six times four will give you the answer."

Zhang Xiaochi replied calmly, he even wants to set up a private school at the moment, and then teach people to learn mathematics, without teaching too esoteric, mathematics from primary school to junior high school.

However, this idea was quickly denied by him, in this era, it is not a good thing to be too sharp, after all, this innovation is too Chinese era, it is easy to attract attention, you can teach if you want, at least not now, but it is still possible to teach your own people.

"Twenty-six times four?"

This time, Lin Xiaoxi and Zhao Ling'er were even more blindfolded.

"Husband, how is this calculated?"

Lin Xiaoxi asked.

Zhang Xiaochi grinned and replied calmly.

"Next, it's time for the ninety-nine multiplication table."

"If you want to complete the quick calculation, the ninety-nine multiplication table is very useful."

Subsequently, Zhang Xiaochi used a brush to write out the ninety-nine multiplication table in ancient form.
