Late at night, the mountains are extremely quiet, and on such a midsummer night, even the "buzzing" sound of mosquitoes is nowhere to be found.

Above the high mountain peaks, an astronomical observatory stands.

An antenna, like a huge ear, looked up at the starry sky, and listened to the ultimate secret of the universe that might be hidden among them in this quiet night.

Today is Wang Hongqi on duty. He is guarding the data feedback screen of the radio telescope. As usual, he hears the sound of his heart pulsing.

He is the old man here.

He sent away hundreds of elderly people from his colleagues.

He was used to the loneliness here, he was used to the unknown article here. Once, he thought he would die here and be buried in this sea of ​​stars above his head.

Before this, his only throbbing was the child. For the sake of his child's future, he went to the capital to participate in the program of Love Potato.

But when he returned to this quiet place today, he remembered the young man in the recording studio and his ball.

He unscrewed the pen, and the iridium particles on the tip rubbed against the paper, making a rustling sound.

I still learned sketching skills in college many years ago. A sphere outlined with lines appeared on paper.

The experts and professors who went with him didn't take this ball very seriously, thinking it was just a display of the latest digital technology, and thinking it was just a gimmick.

Take the money and leave.

They came to the show not for the truth, they were just for the money.

In the experiment, in the project team, bullying graduate students and scientific research dogs are already tired enough, so why do you have to change the place and repeat all this?

Wang Hongqi's primary purpose of participating in the program is also for money.

However, he felt that the ball was not that simple.

It's so much like a real planet.

Its realism does not come from its visual wonder that seems to be squirting out the screen, but from the rich details.

You should know that even when doing astral computing and applying for supercomputers, there are many "unimportant" parameters to be discarded.

Is it because they really don't matter?

No, not, but because they consume too much computing, and then because they are not that important.

Although cutting-edge scientific research seems difficult, it is actually no different from the ideal physical world in junior high school physics books.

because……

After all, it's still an ideal world.

However, the ball floating on the screen, with many "unnecessary" elements, are all appearing.

This attracted him a lot.

Originally, he wanted to chat with the eloquent young man at the meal time after the show ended.

But who could have thought that this seemingly cheerful young man would just run away from his meal?

Although he also asked for his contact information from the crew, he was only good at sending emails to contact others on the Internet, and found that he could not use any of the contact information he had registered above.

Perhaps, for others, WeChat is already a must-have software.

However, in a place like the astronomical observatory, where the electromagnetic environment needs to be pure and even a microwave oven cannot be used, mobile phones are not allowed to exist at all.

Every time I log in to the computer, I have to scan the WeChat code with my mobile phone. Obviously, there is no way to use it in such an environment.

After all, there are no roped smart phones yet.

How about calling that young man?

Wang Hongqi took a look at the landline and began to write and draw on the paper. He sorted out the questions he wanted to ask in a category, and planned to call him during the day after the duty was over.

—————

In the night when the moonlight is quietly shining.

Xue Wang did not sleep, but instead looked for his next home for his mammoth-headed gold.

Wang Tao has promised him to create life together.

However, spiritual identification requires a material basis.

If you don’t have money, what research should you do?

Therefore, he needs to cash out his mammoth-headed gold.

It happened that he had a junior high school classmate who opened a gold shop at home.

But... he was a little doubtful, could a gold store be able to quickly cash out so much gold, but he always had to try it, right?

"Open the door, I'll go downstairs to your house." Zheng Peng, the young owner of the Jinshang, said on WeChat.

Xue Wang pressed the unit door and opened the door and stood at the door waiting.

"Why did you ask me to come mysteriously? You haven't made it clear on WeChat." Zheng Peng went upstairs and asked when he saw Xue Wang.

"I have some gold and want to ask you how to sell and cash the fastest." Xue Wang said in a low voice, pointing to the master bedroom and whispering, "My parents are sleeping."

Zheng Peng also lowered his voice, and said with his head tilted like a spy, "Just bring it to the store and sell it. What should I do if I discuss it."

"I can't hold it..." Xue Wang replied in a low voice.

"Can't hold it? How heavy can it be? Where is it? Let me see." Zheng Peng said with disbelief.

For Zheng Peng, who can ride a bicycle to and from hundreds of kilometers to purchase goods in a single day, he clearly knows the weight of gold.

Even hundreds of thousands of gold is not heavy, and even the pockets of the pants can be stuffed.

"Come with me." Xue Wang asked Zheng Peng to come in and then gently closed the door.

Xue Wang was in front and Zheng Peng was behind. The two tiptoed to Xue Wang's bedroom.

Zheng Peng, who has been here more than once before, sat directly on the fabric sofa, "This is the sofa you bought, it's a bit hard."

"It's not considered a purchase." Xue Wang saw him sitting on the sofa, and didn't know what to say, so he wanted to speak but stopped.

"What's wrong? What's the gold you want to show me?" Zheng Peng saw Xue Wang closing the door and let go a little.

"Please lift your butt." Xue Wang said

"Ah?" Although Zheng Peng was very confused, he still raised his butt.

Under the illumination of white LED light, the bright gold seemed to be shrouded in light.

"Is this gold?" Zheng Peng looked at you teasing me.

"Yes." Xue Wang nodded.

"It's a little less..." Zheng Peng touched such a large piece of gold, looked up and down again. He took out the knife in the key's mouth, dug out a small piece from it, placed it on the windowsill, burned it with the outer flame of the windproof lighter, and it turned red at a speed visible to the naked eye.

After becoming red, Zheng Peng took away his inexpensive lighter.

I saw that the small bit of metal quickly faded away from red and turned back to its original appearance.

Zheng Peng picked up the small metal particles that became slightly rounded because of the slight melting, and said with a look, "Real gold is not afraid of fire refining, and the purity is very high. If the purity is not high, it will not conduct heat so quickly and will not turn red so quickly. If there are magazines in it, it will also be due to the different melting points, and when it solidifies again, you will see that there are fine metal particles impurities inside it.

Although I don't know the specific purity, but... you posted it.
Chapter completed!
