How did it come about? "I'm not angry. It's because my father is ill and can't spare any extra time. I'm going to leave now. If I have time in the future, I will come back to Grandpa Li's house to bother me!" Ling Yun gave a respectful salute and took half a step back.
, turned around and was about to leave.
"No, no, no, no, boy Ling, wait a minute, I've convinced you. I said, I said, can't you do it yet?" Seeing Ling Yun decisively withdrawing, Li Chuan hurriedly ran in front of him and stopped him.
In fact, the moment Li Chuan nodded in agreement, Ling Yun slowly stopped and raised the corner of his mouth slightly, showing a look of success.
"Ahem, Grandpa Li, it's really not the reason why you didn't say anything. I just suddenly remembered that my father's body has recovered a lot and no longer needs special care." Ling Yun turned around and looked at Li with a smile.
Sichuan.
"You kid, it's in vain that I've been so kind to you, and you even lied to me." Seeing his appearance, Li Chuan didn't know that he had been deceived, so he had to give him a cursing look.
Ling Yun smiled and said nothing, quietly waiting for his follow-up.
"Hey, life is really scary." Li Chuan sighed for no reason, and then he calmed down for a moment, and then slowly explained the cause and effect of the incident, "Actually, it's like this, I have an old friend..."
Looking back, time seems to go back to the age when I was studying.
As Li Chuan talked, he took out the letters that he had exchanged for many years. He didn't know what to look at, but he was shocked when he saw them.
It turns out that when Li Chuan was a young man in private school, there was a classmate who always liked to make trouble for him. Whether it was reading or writing, he always wanted to compete with him.
The man's name was Wang Chubai, because both of them were high-spirited young men at the time, so how could Li Chuan be afraid of him? In the end, no one was convinced, and they both liked to take written tests no matter what they did.
The two went back and forth, winning and losing, but overall Li Chuan lost more.
Suddenly one day, Wang Chubai found a magic problem from nowhere, approached him and said yes. If he could solve it, he would obey him. In the future, he would not go to the east if he asked, and vice versa.
Seeing him so steadfast in his vow, Li Chuan was moved, wondering how I would trample you under my feet this time.
So I happily took the problem he handed me, looked it up and down, thought about it, but still couldn't figure it out.
Unwilling to admit defeat, he held the yellow paper in his arms for three days, and finally had to admit defeat.
But how could he give up just like that? If he gave up like this, he would definitely be shorter than him when we meet in the future.
So he searched the streets and alleys of the county and found a magic question, which he handed over to him, using the same harsh words as Wang Chubai did before.
It is conceivable that Wang Chubaiduo did not solve it in the end.
In the future, when the two of them had a dispute, they would give each other a solution to a technical problem. The original saying was that if you can solve it, you are considered good. If you can't solve it, don't talk nonsense.
As things went on like this, until finally Li Chuan stopped going to school, and the two of them also exchanged letters.
In addition to cordial greetings and recent situations, there will be a magic question in the second half, with the harsh words: If you have the ability, solve it for me.
Over the years, the two of them have collected various technical questions, including one letter and one question, but most of them ended up without solutions.
It wasn't until that year that he met Ling Yun, and all the technical problems he had accumulated for many years were wiped away.
He arranged every question solved by Ling Yun neatly one by one, and when subsequent letters were sent out, they were always accompanied by the answers to previous questions.
This anomaly caught Wang Baichu's attention, and he didn't understand why he solved the problems he had accumulated for many years overnight.
So he began to find some more difficult technical questions than before. Sure enough, this time Li Chuan's reply to the letter was much slower than before. He bluntly said that he must not be able to find help.
Who would have thought that when Li Chuan saw him being so sarcastic, he started to reply, saying that if you have the ability, you can figure it out? If you don't have the ability, you just keep talking nonsense.
When Wang Baichu heard this, he thought that asking others to solve something was considered a skill?
Li Chuan smiled and said, if you have the ability, you can also find it. Finding someone to help is also a skill. If you can't find someone, don't just rely on it.
Wang Baichu: You are cruel...
Ling Yun looked at their correspondence and couldn't help but feel ashamed.
Ling Yun couldn't help but look him up and down. He looked like two old children. He smiled and said, "Grandpa Li, you are really as ambitious as before!"
Then she looked at him expectantly and said, "Boss Ling, you see, you know the cause and effect of this, right?"
Li Chuan watched him rub his hands and smiled. He didn't look as stern as teaching students in the classroom at all. He looked more like an old man next door, with a kind and amiable face.
Ling Yun laughed, "Of course."
How can asking someone for help be considered cheating?
Furthermore, Li Chuan has also made it clear that if you have the ability, you can find him. He believes that with these harsh words, Li Chuan's old friend will definitely find help regardless of the circumstances. This is the tacit understanding between the two people who have been fighting for many years.
As his first teacher and grandfather next door, Li Chuan had no reason to let him lose.
Ling Yun opened the yellow paper again and took out the paper, ink, pen and inkstone. Just as he was about to start writing, Li Chuan stepped forward and asked, "Boss Ling, don't you think about it before you start writing?"
"No, no, no, no need for such a simple question."
As soon as these words came out, Li Chuan looked at him with aggrieved pout. Why did this make him, an old man, feel so uncomfortable?
When Ling Yun saw Li Chuan pouting glumly, he realized that what he just said had hit him hard.
"Ah, I mean, I will calculate directly on this yellow paper." Ling Yun hurriedly typed.
Li Chuan pursed his lips and became happy this time.
So Ling Yun listed two sets of equations on yellow paper. Li Chuan took a breath and asked puzzledly, "Boy Ling, how did you get this?"
Ling Yun scratched his head and thought, how should I teach you?
Can you tell at a glance?
If he said that, he probably could eat him up with Li Chuan's eyes.
Ling Yun pondered for a moment and said thoughtfully, "Well, from the question we can see that we can have y hens, x roosters, and (100-x-y) chicks."
"What consciousness does this letter represent?"
Ling Yun choked and was speechless.
"It means unknown number." Ling Yun forced himself to explain, but it was better that he didn't speak. When he did speak, all the words Li Chuan couldn't understand.
“What is the unknown?”
Ling Yun:...
What are the unknowns?
This sentence suddenly appeared in Ling Yun's mind. The gap between the two was like a chasm.
"That's right, that's right... Anyway, you just need to know that he got it this way. We don't need to know the other meanings." Ling Yun could only brush it off.
"Oh!" Li Chuan nodded thoughtfully.
"What about this?"
"..."
What a crime! What is this?
Until later, Ling Yun didn't know how to get home, and all he could think about was, where is this? What is this? How did this come about?
Until he returned home, his mind still felt like it was being twisted by a rope, making him dizzy and messy.
