merit book

Rong Yuan once read a saying before: If the 46 billion years since the birth of the earth are condensed into 24 hours a day, then in the last 3 minutes of the day, human beings will appear in full bloom; It didn't appear until one minute and ten seconds before midnight.As for the 5000-year history of civilization that the people of Sugarland have always been proud of, there is not even a second in the life of the earth.

If there is another kind of creature, another kind of creature whose basic unit of time is the life span of the earth, in their view, the earth on which human beings depend may be just a small speck of dust, which can disappear between heaven and earth with a wave of hand .However, the human beings on the earth live so short that it cannot even be counted as the blink of an eye, which is unimaginably insignificant.Just in this blink of an eye, human beings have reproduced from generation to generation, and have experienced countless dynasties and endless joys and sorrows.

There is an old saying in Tangguo that summer worms can’t be used to describe people’s short-sightedness. However, people who talk so eloquently may be the "summer worms" in this sentence.A tortoise is three thousand years old, and it only takes three days to float. However, the life of three thousand years may not be much richer than that of floating in the morning and evening.Humans are not floating, so how do we know what kind of ups and downs it has experienced in its short life?

Just like micron people, if humans can see their existence, they may find that such creatures may not even have a cup of tea from birth to death, and they will be full of superiority and sympathy for them.Little do they know that in the eyes of the micro-humans, human beings are extremely slow and clumsy giants. In the time it takes a human to blink, if they want, they can run back and forth hundreds of times on the human body.In the short time that humans see, their lives burst out with no less light.

When Rong Yuan became smaller again, he put his energy into researching the expansion principle of fluffy marshmallow.He let the pea press the marshmallow to change it, and he got into the candy to observe and study.As he expected, when he got smaller, Pea's movements seemed very slow to him, and a simple pressing action took dozens of times the usual time.

Two days later, there was a light rain in city b.After the rain, when Rong Yuan went to the tribe of the Microman again, he found that the strange jungle on the leaf had been replaced by a group of mushroom-like colonies, and the Microman disappeared.

……

The plane took off from the ground with a huge roar, and the ground gradually moved away. Gan was lying on the window and looking down, with a look of fear and curiosity. It seemed that this was the first time he had taken a plane.This is actually the first time for Rong Yuan, but he has piloted a rain shuttle that can fly into space, and he looks down on the slow speed and closed plane, so he behaves very calmly.

The long training time has finally come to an end. Now they are going to participate in the tea country where the international mathematics competition is held. Whether it is a snake or a dragon, it all depends on this final battle.Because of his nervousness, Yu Yizhuo tightly grasped the armrests on both sides with both hands.Ni Zihao, wearing earphones and wrapped in a blanket, was already leaning on a chair and getting ready to go to bed. His mother was still accompanying the whole trip at her own expense and was persuading her son to chew some gum.

After Gan Zheng looked at it curiously for a while, he lost interest, turned around, and saw Rong Yuan diligently writing and drawing on the paper, with a look of total concentration, which is rare and serious.She stretched her head over to look, and couldn't help yelling "ah".

"What's wrong?" The teacher who was sitting in front of the team heard the voice and turned to ask her, Rong Yuan also looked over.

"No...it's nothing." Gan Zheng quickly waved his hands, and after the teacher turned back, she asked Rong Yuan in a low voice: "You...don't you want to participate in the chemistry competition?"

She saw that what Rong Yuan wrote on the paper was a bunch of chemical reaction equations.Although she couldn't recognize the reaction formulas of the substances, she had attended high school chemistry anyway, so she wouldn't confuse chemical formulas with mathematical formulas.But two days before a math competition, doing chemistry problems?

"Just interested." Rong Yuan glanced at her and said.He knew Gan Zheng's chemistry level, and he didn't worry about what she could see, so he continued to calculate and balance.

After using more than a dozen fluffy marshmallows in a row, he finally figured out that when the candy is under pressure, there are two substances mixed inside the candy, and a violent reaction occurs, causing the marshmallow to undergo a rapid explosion without losing its own characteristics. The expansion of the two substances was also obtained through direct observation at close range.In theory, as long as there is a chemical formula, any substance can be synthesized from scratch using other substances, but of course it is not as simple as this in practice.Different chemical reactions require different conditions. Humidity, temperature, pH, material form, etc. must be taken into consideration, and cost issues must also be considered for large-scale promotion in the future.He spent a few days and only deduced a small part of it.

Gan Zheng saw how devoted he was, swallowed the words he was about to blurt out, and just watched the team leader sitting in front of him uneasily, for fear that he would turn his head or get up and walk over, and find Rong Yuan's "not doing his job properly".

……

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 that his eyes were a little tired, he put down his pen, stretched his neck, put away all the calculation papers, unfastened his seat belt, got up and went to the bathroom.Ni Zihao's mother saw her, pushed her son, and asked softly, "Haohao, do you want to go to the bathroom?"

Ni Zihao stared blankly for a while, then nodded, rejecting his mother's request to accompany him.There is only one straight path between the seats, no matter how confused he is, he will not get lost in this situation.As soon as Ni Zihao walked to the front of the bathroom, he saw Rong Yuan pull open the door and come out with an inexplicable smile on the corner of his mouth.

"What's the matter? You laugh so weirdly." Ni Zihao asked a little strangely.

"It's okay." Rong Yuan instantly returned to his usual indifferent look, but there was still a bit of interest in his eyes.

"Oh." Ni Zihao nodded, he has never been curious about people or things.The question is subconscious, and he doesn't really care what answer he gets.

Rong Yuan didn't go back to his seat, but pushed out the earphones and stuffed them into his ears, then walked to the toilet in front of the cabin, locked the door, knelt down and took out two rolls of tissues, fiddled with them for a while, and removed a metal plate, reveal what is placed inside.

A row of yellow bullets were tightly stuffed inside.

Rong Yuan chuckled, put on his gloves, and took out all the bullets.

……

There is no real-time monitoring on the plane, and there is no network signal, so peas are almost useless here.After returning from the bathroom, Rong Yuan didn't sleep, he asked the stewardess for a bottle of mineral water, leaned on the back of the chair, and watched the passengers going in and out of the bathroom.

The flight from city b to city cx in the tea country was very long, and passengers got up to go to the toilet from time to time.

Soon Rong Yuan locked on a person.

He looked like a very ordinary man who had entered a mid-life crisis, with a large area of ​​baldness on his head early on, and a circle of sparse hair around him.Wearing black thin-rimmed full-frame glasses, he looks ordinary, but his expression is a little unnatural.Although it is midsummer, it is still a bit cold on the plane.He was wearing a gray-blue long-sleeved jacket, light black trousers, and deliberately pulled the jacket together.

Rong Yuan narrowed his eyes slightly, staring at him coming from the front, when passing by, he smelled a faint smell of tobacco on his body.

—Could it be that this is actually an old smoker who sneaks off to the bathroom to smoke?

Although items such as matches or lighters are not allowed on the plane, there are always people who are addicted to smoking and show their skills, just to secretly enjoy their addiction during the flight.Rong Yuan's suspicion of him weakened a bit, 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. When he walked by, the smell of cigarettes on his body became stronger.

The middle-aged man returned to his seat, and the passenger sitting behind him also stood up and walked back.This is a man in his 30s, with a handsome appearance, wearing a large denim jacket.He seemed a little worried about the safety of the plane, and he carried a boxy business bag with him while going to the toilet, and at the same time kept looking at the seats on both sides.

Rong Yuan turned his head to avoid his sight, and waited for the man to pass by before turning to look at him, frowning slightly.
