Zhou Xuan turned his head and arched his hand, and said: "Mr. Qian, I really don't understand meteorites, even if a piece falls from the sky, I can still throw it for a naughty child." But I recognize magnets, especially those of this shape, and they are very old and come from ancient times. ”

"What?!" Qian Cheng's eyes were about to pop up, and he couldn't cry or laugh, "Dong Zhou, of course the magnet is also magnetic, but it's different from this one!" Hehe, can it be that I have collected it for so many years, and I can't even tell what is a magnet and what is a meteorite? ”

Practice tested the true knowledge, Zhou Xuan took out the key in his pocket, and sure enough, he got close to the so-called meteorite, and sure enough, the key began to shake, proving that it was magnetic.

Qian Cheng lost his stability and grabbed his hair hard, "Some meteorites will also have partial magnetism, which doesn't prove anything." ”

"But it's a magnet, and the shape was made in ancient times." Zhou Xuan insisted on his own judgment.

"If it's ancient, it's worth a lot of money, how can you tell how old it is?" Qian Cheng lost face and asked further.

"For me, it's simple, I know who made this magnet."

Zhou Xuan was categorical, Yu Jiangzhou was about to collapse, Qian Cheng was a good friend of her father, she couldn't believe that she would be deceived.

"I want to hear about it!" Qian Cheng also arched his hand, snorting angrily and was very unconvinced.

"Zhang Heng of the Eastern Han Dynasty was an outstanding astronomer in ancient times, and the world knows that his invention of the geodynamic instrument has a profound impact on later generations." Zhou Xuan said.

"Of course I know Zhang Heng, and his name has also been left in space." Qian Cheng frowned, referring to the named asteroid.

"Zhang Heng loves mechanical manufacturing, and his creation is not only the geodynamic instrument and armillary sphere, but also the Sinan car." Zhou Xuan reminded.

Qian Cheng frowned, pondered for a moment, and said, "But the material of Sinan's car is not made of magnets. Dating back to the period of the Yellow Emperor, it is said that he manufactured the Sinan car, but the conditions of that era were not allowed, and there is no way to verify this statement. ”

"But, Sinan is always made of magnets, right?" Zhou Xuan asked.

"Yes, but what does it have to do with Sinanche?" Qian Cheng asked.

"This is the magnet placed on Sinan's car, which is used to guide the direction."

Qian Cheng was stunned for a moment, and then a mocking look appeared on his face, "Dong Zhou, who else doesn't know today that the magnet guiding the direction on Sinan's car is in the shape of a spoon, if so, the workmanship is too rough!" ”

"Mr. Qian, can you buy a magnet in the shape of a spoon? Have you ever heard of who made a magnet in the shape of a spoon? Zhou Xuan asked.

"This ......" Qian Cheng couldn't answer.

"Our Linxing scientific research base at Linda is currently developing an earthquake-proof house, which uses the principle of magnetic levitation, and Professor Tang is also a top expert in this field. He once said that the widely circulated Sinanche graphics are fake, the magnet cannot be made into the shape of a spoon, does not conform to the principle of magnetic pole distribution, and lacks stability. Zhou Xuan said.

Qian Cheng didn't know what to say for a while, and held back for a long time before saying: "Dong Zhou, if this is the magnet on Sinan's car, it happened nearly two thousand years ago, and the age is too old to verify it at all?" It is worthy of being a senior disciple of Principal Yan, I admit your erudition, but it is too arbitrary to say that meteorites are ancient magnets. ”

"I can be sure that this is the magnet used as a magnet on Sinan's car!" Zhou Xuan insisted.

"Zhou Xuan!" Qian Cheng called his name, and his whole body trembled with anger, "You didn't come to find fault on purpose, did you?" ”

"Of course not, Mr. Qian, I can prove it to you."

"Okay, I'll see how you prove it to me!"

"I need ink!"

"Give what you want!"

Holding the meteorite, the group came to the living room, Zhou Xuan wanted to come to seal the mud, took the stone and dipped it on it, Qian Cheng covered his chest and almost fainted, and said angrily: "Isn't it time to stamp?" ”

"Yes, I need a piece of paper."

Here you go!

Syllable!

Zhou Xuan printed it according to the paper, and the so-called air seal on it was stretched out, Zhou Xuan straightened the paper, put it in front of Qian Cheng, and asked, "Mr. Qian, do you see what's coming?" ”

"Nope!"

"I need a pen!"

Here you go!

Brush brush, pen wandering dragon, Zhou Xuan added some strokes under the imprint, everyone was stunned, it was two big seal characters, I don't know what it is, but I am sure it is a word!

Qian Cheng's face is blue and white, there will be no lettering on the meteorite, if it is a coincidence of natural texture, but such complex and regular strokes, the probability is smaller than winning the jackpot.

Zhou Xuan had proved that this stone did not come from the sky, but was man-made, and there were two large seal characters on it, but because of the long time, the handwriting was worn out, and only most of it was left, and Zhou Xuan made up the other parts.

Qian Cheng was speechless, as if he had even deceived his friends and lost face. Yu Jiangzhou wanted to comfort him, but he didn't know what to say, and the atmosphere was very embarrassing.

After being silent for three minutes, Zhou Xuan broke his loneliness, "Mr. Qian, this is a Si word, which represents the south, and it is also the meaning of guidance, and it is the special mark of the Sinan car built by Zhang Heng. The following character strokes are a little more complicated, it is the Hengzi, you can find a calligrapher who is proficient in the big seal to identify. At that time, there were many Sinan cars built according to this principle, but Zhang Heng personally participated in only ten cars. Mr. Qian, you are really lucky, speaking of which, the value of this magnet far exceeds the price just now. ”

Qian Cheng slapped his head and laughed, he was arguing with Zhou Xuan just now, ignoring the original value of this thing, if it was really the magnet of Sinan Che, the value could not be measured by money.

"Zhou Xuan, Qian Cheng is not good at learning, so you can see the joke."

"Mr. Qian, I just happen to know. If Jiang Zhou bought it just now, from the perspective of personal relations, we would not lose money, but since we know the truth, we don't want to hide it. Abruptly, I hope Mr. Qian understands. Zhou Xuan said sincerely.

"It's me who is abrupt, Zhou Xuan, I am convinced, before I only knew that you were a calligrapher and a Go master, but now it seems that you are still a collector and appraisal, amazing, a rare all-rounder!" Qian Cheng was very happy and gave a thumbs up.

Yu Jiangzhou breathed a sigh of relief, but the last words Zhou Xuan said to her made people feel very uncomfortable. is used to dictatorship, everyone is mentally retarded, but it is not as simple as Jiang Liang, what Zhou Xuan said is right, and what Zhou Xuan does is also wise.

and Zhou Xuan discussed many things in the Eastern Han Dynasty, and Qian Cheng laughed heartily from time to time, admiring and loving this young man from the bottom of his heart.

"Jiang Zhou, there are not many boys like Zhou Xuan, you must hurry up." Qian Cheng reminded.

"Good!"

I thought that Yu Jiangzhou would be ashamed to reply that the two were just friends, but I didn't expect Yu Jiangzhou to agree happily, and Qian Cheng laughed again, saying that he was happy to be with young people.

Knowing that it was a magnet placed by Zhang Heng himself, Qian Cheng cherished it even more, and he would not sell it for any amount of money, but asked Yu Jiangzhou to come for a trip, Qian Cheng felt that it was inappropriate, and generously gave a thumb-sized meteorite for his friends as a souvenir.

couldn't refuse, Yu Jiangzhou had no choice but to accept it, and repeatedly expressed his gratitude.

"Mr. Qian, can you go to your bedroom and have a look?" Zhou Xuan said.

"Absolutely!"
