We Live In Nanjing

  Chapter 20 Slow Time

  Time capsule.

  Bai Yang wanted to buy this thing for a long time.

  His plan is obvious. BG4MSR claims to live in 2040, so as long as Bai Yang sends a slow delivery that spans two decades, if the other party can receive it, it will prove that what she said is true.

  It sounds simple and straightforward, but when I think about it, it is difficult in practice. It is necessary to prevent cheating, fraud, lying, and loss. It is also within the reach of a high school.

  Place an order!

  Bai Yang bought a small time capsule, made of stainless steel, and also included two wrenches and a shovel for 68 yuan each.

  It’s so expensive, it hurts for a while.

  What should I give?

  What should be put in the time capsule?

food? drug? souvenir? A letter?

  No, these are not important.

  The important thing is the timer. It is a watch. Poplar needs a clock that can keep time. At that time, the optical capsule was dug out from the ground, and the clock reappeared. It can tell people how much time has passed.

No clock can stay in a time capsule for twenty years and still run normally. The battery life of an electronic quartz watch is only five to ten years. Automatic mechanical watches do not require batteries. They use a tourbillon to wind up, but rely on external vibrations to provide energy. , Long-term standing will stop the pointer.

  What about this?

With the current advanced technology of mankind, it is certainly a matter of minutes to create a timer that can last for twenty years, but Bai Yang can’t do it. He is just an ordinary high school student with limited ability and financial resources. His greatest reliance is It is the shopping sites Taobao and Jingdong.

Bai Yang tried to search for "timer" on Taobao, and the results obtained were mostly ordinary electronic clocks. Using his toes to think that they could not last for twenty years in the time capsule, Bai Yang's demand sounded simple and tricky to do. Only a clock is needed, no bells and whistles are needed, just timing—listen to it, how simple it is. Isn’t it part of a clock to keep time?

  But how long will it last?

  At least twenty years.

  This is not easy. It is not easy to achieve the ultimate in simple functions. Bai Yang really couldn't find a suitable goal for a while.

  He sat in a chair, staring at the phone screen, lost in thought.

  Twenty years is too long. In daily life, except for the house where one lives, and the furniture used in the house, very few things are designed for use in twenty years.

   "Twenty years..."

   Bai Yang frowned and murmured, playing with a coin in his hand.

It was a Morse code practice coin. Bai Yang bought it when he was practicing equal-width reports. It was about the size of an ordinary one-yuan coin, but the Morse code and their corresponding letters were engraved on the front and back. It looked golden, but in fact It is made of stainless steel and plated with copper.

But in the end Bai Yang didn’t develop his ability to send newspapers. The old man said that he would definitely be abolished by practicing blindly. The bad habits he practiced could not be changed. Bai Yang didn’t believe it, and finally he passed the training, but Bai Yang didn’t admit that he was himself. For the problem, he attributed the blame to the pirated version of the Changshu K4 key he bought on Xianyu.

   "Twenty years, how can we survive these twenty years?"

  This problem is not that complicated at first glance.

  Thinking about it carefully, I realized that it was extremely difficult.

  When time itself becomes a stumbling block in front of you, what you have to face is the most powerful force in the world.

  Since artificial creation is unreliable, one can only hope for the physical laws of the world itself—changes in nature have always been measured in millions of years, and only twenty years are just a flick of a finger.

  The first thing that poplar thinks of is oxidation.

  "Oxidation?"

  Iron oxidation, or copper oxidation.

  Iron is oxidized to iron trioxide, the color is red, and copper is oxidized to copper oxide, and the color is green.

  If poplar can take advantage of the color change caused by metal oxidation, for example, when BG4MSR digs out the time capsule, she will see the metal time marker placed in the capsule.

  At this time, Bai Yang only needs to ask the other party about the color of the marker—this thing cannot be faked, and the other party does not know the meaning of the color, so he cannot lie—to know whether the girl is telling the truth.

   "Can this method work?"

   "It won't work."

  White Yang shook his head.

   does not work.

  The time capsule is strictly sealed, and it is not breathable at all, so there is so much oxygen.

  The second thing that Bai Yang thinks of is evaporation.

He thought of the legend that Qin Shihuang’s mausoleum was filled with mercury, rivers, lakes, and seas with mercury, rivers, lakes, and seas could still be sailed. In fact, with the terrible density of mercury, as long as you are not afraid of death, everyone can float on the water with iron palms, and mercury volatilizes freely. The speed is extremely slow. If he puts 0.5 grams of mercury in the time capsule, it may take more than ten years for the mercury to completely volatilize...

  When BG4MSR opens the time capsule twenty years later, she will see a high concentration of mercury vapor.

  This will not work either.

  Isn’t this harmful?

  White Yang scratched his head.

  This also doesn't work, that doesn't work either. What should I do?

Unfortunately, there is no second person present to discuss this issue with him at this time. Two brains are definitely better than one brain. Bai Yang sits in a chair and meditates alone. It is a pity that he is a primate mammal rather than a large reptile. Otherwise, he can have a brain on his **** to help him think. In silence, the small alarm clock on the desk is ticking away. The night is very deep, and the rain outside the window seems to be still falling.

   Bai Yang was lying on the bed that night, unable to sleep, his eyes widened, staring at the ceiling in the darkness, thinking about this question over and over in his mind.

He hopes to find a means, a means that cannot be faked. It is not interfered by any external force, and the result is not tampered with by anyone. Only the iron of this world can control its changes, just like the death of trees and turning into coal, and rocks being destroyed. Erosion forms caves-let the world itself be a timer, only in this way can it be called iron proof.

   said so, but it is easier said than done.

As a high school student, it’s still too difficult to find such a way. Bai Yang thought silently, maybe another person, someone who is older and more experienced in life, will come out with a single shot. Or too young and too little knowledge... Can she think of a good way to change brother Yan? Can you think of a good way for Ho Leqin?

  He Dashao has been knowledgeable since he was a child, and he has gone abroad more often than he has gone to the province. Maybe he can think of a good way?

Forget it, Bai Yang shook his head, He Leqin failed the physics exam again and again, and his chemistry test score was lower than that in physics. His daily homework had to be rescued by Bai Yang and Brother Yan. Microsoft Flight Simulator Half-Life...Half-Life is really a bad translation. It can be called the top ten bad Chinese game translations...Who originally translated it into Half-Life...What was the original name of Half-Life?

  Poplar is thinking about endlessly.

  The original name of Half-Life?

  It seems to be half...

half life?

  White Poplar was taken aback, and sat up in shock while dying.

half life!
