...

An off-road mountain bike was on its way to the Machem camp.

Physicist Emily stared at the tired dark circles, feeling a little drowsy. However, the ambiguous eyes that the sisters kept throwing her into her heart.

She looked at the handsome oriental man sitting next to her angrily and agreed to ask for physics knowledge? No, right? He did ask for physics knowledge. And this consultation took a whole night, and she had the opportunity to go to bed at around five o'clock in the morning.

Don’t get me wrong, just ask for physics knowledge in a literal sense. He goes from the principle of flame, the structure of plasma, to aerodynamics, to the principle of rocket launch, from the structure of the atmosphere, to the linear speed of the earth’s rotation, how to break through the first cosmic speed, the Big Bang, the possibility of the multiverse, and the rationality of the existence of dark matter...

At first she thought he was a subtle oriental man and needed to pretend to be a transitional atmosphere. So she also answered his questions one by one with enthusiasm.

But unexpectedly, she was endless, endless. In the end, she was almost crazy. She was discussing and studying physics knowledge all night. At that moment, she had never hated physics so much.

These are nothing.

When Emily met her sisters with her dark circles and took the bus to Camp Machem, those envious and jealous eyes really made her want to find a hole to crawl into. She knew what they meant. Look at your haggard appearance, even if you are unrestrained, you don’t have to be unrestrained for a night.

She tried to explain that she was really discussing physics for one night, but no one believed it.

"Emily, I have a serious question to ask for advice." Wang Yan was very energetic. With his physique, let alone not sleep for a night. Even if he doesn't sleep for a week, he will still be energetic for you.

"It's coming again..." Emily moaned inside.

"We had a discussion last night that the hot air balloon relies on air buoyancy to fight gravity to lift off. So the question is, assuming that the air density does not decrease sharply due to the height, will the hot air balloon rise in infinitely and escape from the constraints of the earth's gravity?" Wang Yan asked curiously.

"Of course, as long as you maintain enough buoyancy to fight gravity." After all, Emily is an expert in physics. Even if she is not as good as her spirit, she can easily answer Wang Yan's seemingly childish question. "With enough air density, it can obtain continuous buoyancy and maintain the balance of internal and external pressure. And as the height is higher, the gravity is relatively weak, and its rising speed will accelerate."

"What's going on with the first cosmic speed?" Wang Yan said with a frown slightly, "Didn't it mean that you must accelerate to more than 7.9 kilometers per second to break free from the gravity of the earth?"

Emily fainted. She really wanted to strangle this handsome oriental guy to death. Can't you flirt with me well? You asked so carefully, but you really want to fly out of the earth? She had an expression of indifference on her face and replied helplessly: "That means that if you want to escape from the earth's gravity without providing more power, you must exceed the first cosmic speed. Simply put, if you want to leave the earth by relying on the inertia of the movement of objects, you must exceed 7.9 kilometers per second."

"Emily, what do you mean is that as long as there is a continuous source of power, I can ignore the first cosmic speed?" Wang Yan held his chin and said seriously.

"I'll explain it clearly." Emily glared at Wang Yan angrily and said, "If I want to kick you out of the earth, the force of the kick must make your initial speed exceed 7.9 kilometers per second, because I don't kick you continuously and apply force to you later. You must roll out of the earth by inertia. If you can't reach that inertia speed, you will be pulled back by mother Earth. But if I can kick you one after another, no matter how slow the speed is, I can kick you into outer space. Do you understand?"

"I understand, it's easy to understand." Wang Yan said with a smile, "Thank you, Emily, you solved a problem that I have troubled for a long time."

"Emily." The rest of the people were discussing this issue and surrounded them with curiosity. The beautiful boss asked, "So what you mean, if I add more fuel to the plane, I can drive it all the way into space?"

"Bang!"

Emily slapped her forehead and tears almost fell: "Andy, the wings of the plane must rely on air to maintain the liftoff force, and the plane engine is also driven by the air. The higher our atmosphere, the thinner the air, and the air will fall."

She was also drunk. Why didn’t anyone understand such a superficial physics knowledge?

Another student asked curiously: "Emily, it doesn't matter if the rocket takes off, right? Then why not let the rocket fly slowly and continue to fly into outer space?"

"Oh my God!" Emily felt that she was not going to hike for a vacation, but came to teach kindergarten. She patted her forehead and said helplessly, "Your theory is feasible, but we need an extremely huge rocket pole to supply rocket fuel. And the larger the rocket, the greater the driving force it needs, and a vicious paradox will form. In fact, even if you can design a rocket that breaks away from the earth based on your theory, its energy consumption will be far greater than that of existing rockets. Energy consumption is a major issue. Do you know why the closer the rocket launch site is to the equator, the better?"

"I know." Wang Yan raised his hand and said, "Because the earth's rotation has inertia, it is the fastest line on the equator... This can save more power."

"I'm right, do you need a teacher to give you candy?" Emily glanced at Wang Yan and said, "In fact, if the cost of raw materials transportation is not counted, the Kilimanjaro where we are located is the most suitable. First, it is very close to the equator, which means its natural linear velocity is higher. Second, it is very high and farther from the center of the earth than other parts of the equator, which means that the linear velocity is almost at the highest point on the earth. Third, it is naturally six kilometers high, which can save some travel in the atmosphere. Fourth, the atmosphere above the equator is relatively thin, which can reduce air resistance."

After saying that, she used a blanket to make her face dull: "Dear curious babies, Teacher Emily is going to sleep." She just covered her face, but suddenly she lifted the blanket and rolled her eyes at Wang Yan, "By the way, dear Yan. If you really want to learn from Superman to fly out of the earth, you must pay attention to the internal and external pressure issues, otherwise you will burst out like a blow-out toad. Of course, wear a few more clothes by the way, and it is very cold on it. By the way, the warm atmosphere absorbs a lot of ultraviolet rays and the temperature is very high. Be careful to take off your clothes."

After saying that, she covered her face and went to bed, and no one ignored her. She could see that the handsome oriental man was either a brain problem or a novelist. Why was Emily so unlucky? She finally met a handsome and heart-warming person. How could she have a brain problem?

"I understand, thank you Emily." Wang Yan said with a smile.

As soon as she slept, the other girls pulled Wang Yan over.

"Yan, you're too bad, right? You've actually tormented Emily to such a tired look. I really don't know how to cherish you."

"Be more at ease, we will still have to climb mountains these two days."

"Or, we can also study research projects tonight. I don't understand physics, but I understand."

"This..." Wang Yan felt a drop of cold sweat.

...

One day later.

Located in the Italian command center.

Yan Zun was sitting in the command center wearing a mask, using his huge mental power to process information from all aspects at the same time, and was given instructions.

Suddenly.

A handsome old man wearing sunglasses and wearing an Italian handmade suit walked in. He patted Yan Zun on the shoulder, smiled and said in a sympathetic voice: "Why, haven't you caught your apprentice yet? It's okay, let's not hurry, take your time. Haha, I like Comrade Xiao Wang more and more, and I can make you so embarrassed."

"Xiao Feifei, you are one of the most powerful men in the world at least." Yan Zun glared at him angrily, "Are you worried about your identity? You can come out if you wear this outfit?"

"Today, Sunday, I just came back after the week. Can't I rest?" Pope Light pulled down a chair, took off his sunglasses, and said with a straight look, "To be honest, sitting here to see you get defeated is the most comfortable and happiest thing in my life. This gave me a new interpretation and understanding of the word "schadenfresh". The weather is really good today, and it is worth a drink."

"Bang!"

Pope Light snapped his fingers, added a glass of wine in his hand, and took a leisurely sip. It was obvious that he looked like he was not at work today and ran over to watch the show.

"Haha, do you think that stinky brat can escape my palm?" Yan Zun smiled confidently, "I don't believe that he can escape my big search line."

"Have you checked the round-trip plane?" Pope Light said with concern as if he pretended to be concerned.

"In this operation, I have gathered all the power that can be mobilized. Even if he dares to disguise himself on the plane, he will be searched as soon as possible." Yan Zun said calmly, "I have deployed all the channels closely. By the way, he used the deep sea to escape last time. In response to this, I have called several deep sea monsters from the demon prison. They are not only very powerful underwater, but also able to communicate with creatures in the sea."

"Baba!" Pope Light clapped and said, "You have invested a lot of money to capture Comrade Xiao Wang. It's just a pity, why haven't you caught him yet?"

"I'll catch him."

"Why haven't you caught him yet?"

"You..." Yan Zun was so angry that he almost vomited an old blood. Suddenly, his eyes lit up, "Xiao Feifei, do you think that boy would go the other way, traveling through the Sahara Desert, traveling across Africa, and then bypassing the Antarctic... That's right, I almost have no defenses in that direction..."
