Chapter 103: 10,000 meters above sea level
Rong Yuan had read a statement before: if the 4.6 billion years since the birth of the earth were condensed into 24 hours a day, then human beings would only appear in the last three minutes of the day; and the so-called modern humans appeared one minute and ten seconds before midnight. As for the 5,000-year civilization history that the Chinese people have always been proud of, it is less than one second in the life of the earth.
If there were another kind of creature, another kind of creature that used the life span of the Earth as the basic unit of time, in their view, the Earth on which humans depend for survival might be just a tiny speck of dust that could disappear between heaven and earth with a wave of the hand. The survival time of humans on Earth is so short that it is not even a blink of an eye, and its insignificance is unimaginable. In just this blink of an eye, humans have multiplied from generation to generation, and have experienced countless dynasties, endless joys and sorrows.
There is an old saying in the country of Tang that a summer insect cannot talk about ice, which is used to describe people's short-sightedness. However, the person who talks so eloquently may be the "summer insect" in this saying. A tortoise is three thousand years old, but it only floats for three days. However, a three thousand year old life is not necessarily much richer than a floating turtle that lives in the morning and dies in the evening. Humans are not floating turtles, so how can we know what kind of ups and downs they have experienced in their short lives?
Just like the microns, if humans could see their existence, they might find that it takes less than a cup of tea for these creatures to live from birth to death, and they would be full of superiority and sympathy for them. However, in the eyes of the microns, humans are extremely slow and clumsy behemoths. If they want, they can run back and forth on a human body hundreds of times in the time it takes for a human to blink. In the short time that humans see, their lives burst out with a light that is no less brilliant.
When Rong Yuan became smaller again, he focused on studying the expansion principle of fluffy marshmallows. He asked Pea to press the marshmallows to change them, and he went inside the candy to observe and study. As he expected, when he became smaller, Pea's movements seemed very slow to him, and a simple pressing action took dozens of times longer than usual.
Two days later, a light rain fell in City B. After the rain, when Rong Yuan went to the Micron tribe again, he found that the strange jungle on the leaves had been replaced by a group of mushroom-like colonies, and the Micron people were nowhere to be found.
…
The plane took off with a loud roar, and the ground gradually moved away. Gan Zheng leaned on the window and looked down, his expression was both fearful and curious. It seemed that this was his first time to fly. Rong Yuan was actually the first time, but he had flown a rain shuttle that could fly into space, so he looked down on the slow and closed environment of the plane and acted very calmly.
The long training time finally came to an end. They were going to the Tea Country, which hosted the International Mathematics Competition, to participate in the competition. Whether they would be a snake or a dragon depended on this final battle. Yu Yizhuo was so nervous that he tightly grasped the armrests on both sides. Ni Zihao, wearing headphones and wrapped in a blanket, had already leaned back in a chair and was ready to sleep. His mother still accompanied him at her own expense and was persuading her son to chew gum.
Gan Zheng looked at it curiously for a while, then lost interest. She turned around and saw Rong Yuan writing and drawing on paper diligently, concentrating on it. She was so serious that she couldn't help but exclaimed "Ah!" when she leaned over to take a look.
"What's wrong?" The team leader teacher sitting in the front heard the voice, turned around and asked her, and Rong Yuan also looked over.
"Nothing...nothing." Gan Zheng waved her hands quickly. After the teacher turned back, she whispered to Rong Yuan, "Aren't you...not going to participate in the chemistry competition?"
She saw that Rong Yuan had written a bunch of chemical reaction equations on the paper. Although she couldn't recognize what the reaction equations were, she had taken high school chemistry and wouldn't confuse chemical formulas with mathematical formulas. But, two days before the math competition, doing chemistry questions?
"Just interested." Rong Yuan glanced at her and said. He knew Gan Zheng's level of chemistry, so he didn't worry about what she could see, and continued to calculate and balance.
After using more than ten fluffy marshmallows in a row, he finally figured out that when the candy was under pressure, two substances were mixed inside, and a violent reaction occurred, causing the marshmallow to expand rapidly without losing its own characteristics. He also obtained the chemical formula of the two substances through close observation. Theoretically, as long as there is a chemical formula , any substance can be synthesized from scratch using other substances, but in reality, of course, it is not that simple. Different chemical reactions require different conditions. Humidity, temperature, pH, material form, etc. must all be taken into account. In order to promote it on a large scale in the future, there is also the cost issue that has to be considered. He spent several days and only deduced a small half.
Seeing how engaged he was, Gan Zheng swallowed the words that were about to come out of his mouth. He just looked anxiously at the team leader sitting in front of him, fearing that he would turn around or stand up and walk over and discover that Rong Yuan was "not doing his job".
…
More than an hour after the plane took off, most of the passengers in the cabin were drowsy, and a few were playing with tablets or reading books. Rong Yuan felt a little tired in his eyes, put down his pen, stretched his neck, put away all the calculation papers, unbuckled his seat belt, and got up to go to the bathroom. Ni Zihao's mother saw it, pushed her son, and asked softly: "Haohao, do you want to go to the bathroom?"
Ni Zihao was confused for a while, then nodded, rejecting his mother's request . There was only a straight path between the seats, and he would not get lost in this situation even if he was confused. As soon as Ni Zihao walked to the front of the bathroom, he saw Rong Yuan open the door and come out with an ambiguous smile on his face.
"What's wrong? Why are you laughing so strangely?" Ni Zihao asked curiously.
"It's okay." Rong Yuan instantly returned to his usual cold attitude, but there was still some interest in his eyes.
"Oh." Ni Zihao nodded. He had never been curious about people or things. He asked the question subconsciously, and he didn't really care about the answer.
Rong Yuan did not return to his seat. Instead, he took out his earphones and put them into his ears. Then he walked to the toilet at the front of the cabin, locked the door, squatted down and took out two rolls of paper towels. He fiddled with them for a while, removed a metal plate, and revealed the things inside.
A row of yellow bullets were tightly stuffed inside.
Rong Yuan chuckled, put on gloves, and took out all the bullets.
…
There was no real-time monitoring or network signal on the plane, so Wandou was almost useless here. After returning from the bathroom, Rong Yuan had not slept. He asked the stewardess for a bottle of mineral water, leaned back in his chair, and looked at the passengers going in and out of the bathroom.
The flight from City B to City CX in Tea Country takes a long time, and passengers often get up to go to the toilet.
Soon Rong Yuan locked onto a person.
He looked like an ordinary man who was in the middle-age crisis. He had a large bald patch on his head early on, with a circle of sparse hair around it. He wore black thin-rimmed full-frame glasses. He looked ordinary, but his expression was a little unnatural. Although it was midsummer, it was still a little cold on the plane. He wore a gray-blue long-sleeved jacket and light black pants, and he deliberately pulled the jacket up.
Rong Yuan narrowed his eyes and stared at him as he walked towards him. As he passed by, he smelled a faint scent of tobacco on him.
——Could this actually be a heavy smoker who sneaked into the toilet to smoke?
Although it is not allowed to bring matches or lighters on board, there are always people who are addicted to smoking and use all kinds of tricks to secretly satisfy their cravings during the flight. Rong Yuan's suspicion of him was reduced a little, but he still paid close attention to the toilet he entered.
Ten minutes later, the middle-aged man came out of the toilet with relaxed steps and a happy expression. As he walked past, the smell of cigarettes on his body became noticeably stronger.
The middle-aged man returned to his seat, and the passenger behind him also stood up and walked back. This man was in his thirties, a little handsome, wearing a large denim jacket. He seemed a little worried about the safety of the plane, and while going to the toilet, he also carried a square briefcase with him, and kept looking at the seats on both sides.
Rong Yuan turned his head away to avoid his gaze. After the man walked past him, he turned back to look at him, frowning slightly.
