Fish swimming around the world

The crowd cheered. No one expected Jiang Fan to be extraordinary in mathematics.

"However, there is a second question. Please listen carefully, young master."

Mr. Cao ordered someone to bring a big stone over: "I want to know how square this stone is. I don't know how Young Master Jiang taught me?"

The crowd was in an uproar again. The stone was very irregular, with many edges and corners, and there was a big pit in the middle. How to calculate it?

"You old man, you are forcing me! This stone has pits and corners, how can it be calculated?"

Some people who support Jiang Fan angrily accused him.

"That's right, isn't this a deliberate plan to take Young Master Jiang's life? This old man is so vicious!"

Now, even Jiang Fan's camp was in chaos.

"Nangong Xin has made sufficient preparations. He is determined to murder Young Master Jiang today." Lady Jinhua shook her head.

"This old guy is abominable. If anything happens to Mr. Jiang, I will kill him." Lu Zhuer said with fierce eyes and clenched fists.

For a moment, all eyes were focused on Jiang Fan.

Unexpectedly, Jiang Fan laughed up to the sky: "Boring, I told you to come up with something complicated, why is it such a simple question? Your IQ is really worrying."

Mr. Cao's eyes moved. Could it be that this kid can really answer it?

The next moment, Jiang Fan said lightly: "Take a large bucket, pour a known amount of water into it, submerge the stone in the water, mark it on the bucket, then take out the stone, pour water into the marked line, and then pour it into a measurable container. The difference between the latter and the former is the same. It's a boring question."

In fact, there is a simpler way to say it, but Jiang Fan had to say it this way to make it easier for people here to understand.

"Ah? This..." Not only Mr. Cao, but everyone was stunned. It was indeed extremely simple, but why didn't they think of it before?

"Good! Well done, Mr. Jiang!"

"Mr. Jiang is extremely talented, I love you--"

Mr. Zeng couldn't help but exclaimed, and bowed to Jiang Fan: "Mr. Jiang is very talented."

Jiang Fan answered two questions in a row without any hesitation. Nangong Xin and his party were all dumbfounded.

"Mr. Cao, didn't you say that he couldn't answer it?" Nangong Xin was confused and grabbed Mr. Cao.

"... This, I never thought..."

"Good! Well done, Mr. Jiang, what else do you have to say?"

Mr. Zeng coughed, signaling the crowd to be quiet, and looked at Nangong Xin with a smile: "Mr. Nangong, Mr. Jiang has answered two math questions correctly, and it's Mr. Jiang's turn to ask questions next."

Nangong Xin and his party suddenly became nervous. Jiang Fan's math attainments were beyond expectations, and the questions asked by such a person would naturally not be simple.

"Mr. Cao, please be patient, we have also invited a math expert, and we may not lose." Mr. Cao had to comfort him.

Jiang Fan smiled slightly: "It's my turn? Well, let's ask a simple one. It takes ten hours and eight hours for pipes A and B to fill a pool of water. It takes five hours for pipe C to drain a pool of water. Now the pool is empty, and pipes A and B are opened at the same time. After two and a half hours, drain pipe C is opened. How long will it take to fill the pool?"

When the question came out, the whole audience was dumbfounded. The math master on Nangong Xin's side dropped his pen to the ground with a click, and Nangong Xin's heart sank to the bottom of the valley with this scene.

Obviously, he can't do it.

"Huh? Mr. Jiang, this question is weird. How can you calculate it?"

"Difficult, as difficult as climbing to the sky."

The blue-robed old man couldn't help but move his mouth, and a strange look appeared on his face.

"Calculate it, Nangong Xin, why don't you calculate it? Are you dumbfounded?"

Someone shouted.

"Hurry up, calculate it for me, hurry up!"

Nangong Xin was furious, but he could only watch the time pass by bit by bit while the math master scratched his head. Finally, the old man in blue robe coughed and announced: "Time is up!"

"Lost... lost?"

Nangong Xin said absentmindedly.

"Don't panic, young master. There are still two rounds. We may not lose."

"It's all your bad idea. If the other party asks for a question next, how should we respond if he asks to write a poem? Isn't it a loss? This young master's life is over!"

He was really panicking.

Especially when he saw Jiang Fan looking at him with a weird smile, Nangong Xin suddenly felt a chill on his back.

Mr. Zeng said with a smile: "Congratulations, young master Jiang, please ask young master Jiang to ask the next bet."

"Bet on writing a poem, bet on writing a poem!"

Someone in the crowd shouted suddenly.

That's right, everyone thought Jiang Fan would bet on poetry. In this regard, he could almost win. In this way, Jiang Fan would win two out of three games.

"Since that's the case, it's time for me to ask a question... Well, I'm a casual person, so let's bet on my experience. You and I will each draw an object, and the premise is that it must exist in the world. We will give the picture to the witness and tell the purpose of the object, and then you and I will exchange the drawings and guess. Whoever gets the right answer wins, how about that?"

No one expected that Jiang Fan would avoid the trivial and choose such a topic.

"Young Master, why don't you choose poetry?"

Wei Xiaohong was also stunned.

Jiang Fan smiled lightly: "People deliberately choose to bet on the outcome of three games, why don't you give them a chance."

Looking at his relaxed expression, Wei Xiaohong suddenly looked a little dazed. This young man has always been so casual and free, but he is almost omnipotent. An absolutely strong self-confidence comes to the face, which makes people feel impressed.

Mr. Cao's eyes lit up when he heard this: "Sir, our chance has come!"

Nangong Xin had no confidence at this moment: "I don't know what strange things Jiang Fan has made, how can we win?"

Mr. Cao suddenly whispered in his ear: "Sir, I have found a strange thing that has never been seen in the world. Jiang Fan did not bet on poetry, but actually committed suicide. Don't worry."

So, with everyone puzzled and full of expectations, both sides drew a blueprint and handed it to Zeng Daxueshi.

After Zeng Daxueshi looked at the blueprint and listened to the introductions of both sides, he announced that the competition could begin.

The first was Nangong Xin's side. Jiang Fan took out a blueprint with a strange object drawn on it. It was a round object hung by a thin chain with a lid. The lid was open, and there were three pointers of different lengths inside, surrounded by a circle of scales.

"What... what is this?" Nangong Xin swore that he had never seen this thing. Mr. Cao was also stunned. Several people took the blueprint and looked at it repeatedly. In the end, they could only smile bitterly and shook their heads: "Sorry, sir... we don't know..."

Nangong Xin was so angry that he almost vomited blood.

"But, sir, Jiang Fan must have never seen ours. This round is a draw at best. In the third round of fighting, he challenged so many people without knowing his own strength. He will definitely lose."

Nangong Xin finally calmed down.

"Sir Jiang, we can't identify your item, but does it really exist in the world? If it doesn't exist, you are cheating and you will lose." Mr. Cao couldn't recognize what it was, and he didn't believe it existed.

Nangong Xin also realized that if Jiang Fan just drew it casually, it would not count.
