Anyway, his thoughts had been disrupted, Li Jing simply put down what he was doing, looked at Hongfu and asked, "Madam, is there anything wrong?"

Hongfu pulled Li Hao, who was still standing at the door, and said, "Husband, Dejian is already an adult, I feel that I can't always let him idle all day long and cause trouble everywhere."

"What does madam mean?" Li Jing tried to ask.

Hongfu said: "What I mean is to let him learn more about marching and formation with his husband. In addition..., his husband learns one of the best ways to Chang'an, which is just right for teaching this child, so that he can avoid making people laugh at him when he goes out in the future."

After saying that, he pulled Li Hao and gave him a wink.

Li Hao expressed helplessness about my mother's behavior. He didn't think the old man could teach him anything. He hesitated and took a few steps forward: "Mom, why don't you forget it, you see, my father is very busy."

"Hmph, something that doesn't seek to improve." Li Jing, who felt that he was disliked, snorted angrily and said contemptuously: "My evil, I know that the new numbers that are popular at the moment are from your writing, but if you learn a profound and profound way of calculating, you can't understand it by writing a few numbers."

"Yes, what my father said." Li Hao nodded quickly and agreed.

As an old man, it’s okay to just flatter him and make him happy, there’s no need to be serious.

Unexpectedly, his actions made the old man competitive. Without saying a word, he turned to his desk and picked up a notebook and threw it into Li Hao's arms: "I know you are convinced and dissatisfied. This is how you can calculate the food and grass in this account book within half an hour, I will admit that you are calculating some skills."

Li Hao was almost collapsed. With his memory and calculation ability, simple addition and subtraction could no longer cause any difficulties for him. If you really want to calculate such a book, you wouldn't even need a hundred breaths.

"Why, I don't even dare to try it?" Li Jing, who thought he was a little bullying his son, began to run him again when he saw Li Hao not speaking.

"Okay, I'll try." In order to overcome the 'difficulty' in front of me as soon as possible, Li Hao nodded helplessly.

Put the account book on the table, picked up the pen that the old man placed on the table, Li Hao casually found a piece of white paper and started to do so.

However, in order to save some face for the old man, he deliberately wrote the summary of each page on paper. After all, he was not very skilled in writing calligraphy and could be used to kill time.

But even so, it took less than a quarter of an hour to record all the numbers. Looking at the two pages of paper, Li Hao bit his pen and felt a little embarrassed.

Do you want to write down the total number?

If you write it, it will be less than a quarter of an hour, which will make the old man feel embarrassed. But if you don’t write it out..., you have already finished it, how can you kill time?

But Li Hao, who was thinking about how to work, didn't know that the old man was already stunned at this time.

Before handing over this account book to Li Hao, Li Jing had actually calculated it once, otherwise he would not have said the time limit of half an hour. And because he had calculated it, he probably remembered some of the summary of each page of the account book, knowing that the numbers written by Li Hao were not at all wrong.

It's only a quarter of an hour, and most of the calculations have been completed. According to the speed at which Li Hao calculated the summary of each page before, Li Jing did not think that the last step of summary was to add or subtract more than 60 numbers, and it took three quarters of a minute to add or subtract more than 60 numbers.

He was in a daze, his sleeves were pulled. Li Jing turned his head and saw that it was his wife Hongfu.

"How is Dejian's calculations right?" Hongfu was not proficient in math. Seeing his son writing a lot of numbers without saying a word, he couldn't help but ask his husband for verification.

Li Jing didn't say anything, and his old face turned red slightly.

If Li Jing hadn't known his wife's character, he would even think that Hongfu was deliberately cheating him.

Hongfu could not think of so many things. Seeing that Li Jing didn't speak, he urged: "You are talking, right? Dejian's calculations are right?"

"Yes..., right!" Li Jing said awkwardly.

When he reached the answer he wanted, Hongfu murmured: "Oh, then it's only been more than a quarter of an hour. It seems that half an hour should be fine."

Yes, he has no problem, I have a problem.

Li Jing was speechless, looked at Li Hao who was biting his pen and pretending to behave, kicked him, and said depressedly: "What else are you pretending to be? How many are you?"

"Uh..." Li Hao turned his head and looked at the old man, picked up his pen and wrote a number on the paper.

Since it has been seen, it will be boring to pretend.

Hongfu asked Li Jing for advice again. After receiving the old man's affirmative answer, he immediately threw the statement that his son had learned from Li Jing aside, and pulled Li Hao to praise him.

What kind of child prodigy, what's number one, what's much better than your father...

Li Jing was angry and laughing at the side, thinking that he was just asking for trouble. Since this kid could even "invent" numbers, how could he not be proficient in one thing?

It's embarrassing and disappointing, my old face has been completely lost.

Just as he was thinking about how to send Li Hao away, a messy footsteps came from outside the door. Then the housekeeper, Old Chen, was holding a copper basin in his arms, and a look of ghosting on his face, and ran in panic: "Old, master, Bing, Bing..."

Li Jing, who lost his face in front of his son, scolded him angrily: "What's going on? He Ti Tong is in a panic."

"No, no, Master, you see, this ice..." Old Chen was speechless for a moment, and he couldn't say anything for a long time. Finally, he simply put the copper basin in his hand in front of Li Jing.

Li Jing took the opportunity to take a look in the basin, but it was fine if he didn't look at it. He was stunned when he saw it.

I saw a huge piece of ice in the copper basin, which fits completely with the copper basin.

There is only one possibility that such a situation can occur, that is, put the water into the basin and freeze it directly. Otherwise, if the ice is put in, it will not be so suitable.

But the problem is that it is summer now, so how can water freeze into ice?

"What's going on?" Li Jing asked when he stared at the ice in the basin.

"Old, I don't know, just do it according to the instructions of the young master, and then...the water in the basin will turn into ice." Old Chen kept glancing at Li Hao with his light when he spoke, wanting to see but not daring to look at it. He was obviously scared.

Old Chen believes that he has been knowledgeable for so many years with Li Jing, but he can turn water into ice in the summer, so he dare not change this way.
