PS: A child shoe said to me, Han Bao, when you opened a single chapter to ask for votes that day, you said that you had updated twenty-four chapters in three days, but it was actually a mistake.

Then I told the boy, don't you know that my elementary school physical education teacher died early, so the Chinese teacher has always been single, which directly led to my math grades have not been satisfactory.

In fact, I am pretending to be stupid and stunned, like my dead end is so clear, how can there be such a logical error, at least I haven't forgotten two things every day, update, ask for votes......

"Wrong. Bai Chen didn't think about it, and replied directly.

"The sky is round and the earth is round, this is a truth that has existed since ancient times, how can it be wrong?"

"Yes, we have also seen that when there are no clouds, we can vaguely see the arc of the sky, how can this be wrong? Could it be that there is something wrong with our eyes?"

Everyone was unimpressed, and even more thought that Bai Chen was just saying this for grandstanding.

"Then why do you think that the sky is not round and the earth is not square?" Lan Xuan did not question as others, but asked rhetorically.

In her tone, she also seemed surprised by Bai Chen's answer.

Because of this question, she has asked many people.

But everyone's answers, without exception, were all in the affirmative.

The sky is round, and it seems to have become the truth.

Bai Chen replied flatly: "Because I know that our world realm is round, and all of us are standing on a very big ball. ”

"Huh?"

For Bai Chen's answer, everyone was a little confused. Some people think that Bai Chen is crazy.

If they are all standing on top of a big ball, aren't the people at the bottom going to fall?

Lan Xuan frowned, but there was no noise and doubts from others, as calm as ever: "What's the explanation?"

"Have you ever been to the sea?" Bai Chen glanced at everyone.

Lan Xuan and Qu Zhishui both nodded: "I've been there." ”

"Can you see the end of the sea?"

"How is this possible, the sea is so big......

"No one can see the end of the sea, because all of you see the line between the sea and the sky, not because the sea is too big, you can even see the stars in the sky, the stars are far older than the end of the sea, if it is the world is flat. How is it possible not to see the end of the sea. ”

Bai Chen picked up a cup on the table: "If you think of this cup as our worldly realm. We are the ants in this cup, so do you think if this ant is on the other side of the arc, can you see the opposite side of the arc?"

"You said that our World Realm is a big, big ball, but what about the bottom of the ball, aren't the people below about to fall?" Lan Xuan looked at Bai Chen questioningly.

"Because the ball didn't go up and down at all. Someone on the other side of our world. Maybe we think we're down there. ”

"Why didn't you go up and down?"

"Because of gravity. I call it gravity, but at the heart of our feet is a rotating fireball. It can also be said to be the heart of our worldly realm, when it rotates, it generates gravity and firmly grasps everything on the ground. ”

"What you said is your inference, it's a fantasy, and there is no evidence at all. Someone questioned.

"In fact, some people have examined it, but you don't know the way, if you can fly up to a height of 100,000 meters, you will find a lot of things, the clouds are stepping on your feet, everything on the ground will become extremely small, even a city seems to be in your hands. ”

"Nonsense, not to mention whether what you said is true or not, just talking about an altitude of 100,000 meters is impossible, who do you say can fly up to an altitude of 100,000 meters?

"What's so difficult to fly into the sky, as far as I know, there is a very simple way to fly up to the sky, overlooking the feeling of the vast earth, which is unprecedented magnificence, and the world can see it all. ”

Bai Chen said flatly, and everyone looked at Bai Chen's eyes, as if some were yearning, some were suspicious, some were moved, and some were contemplative.

"You said you have a way to fly up to 10,000 meters in the air?" Lan Xuan looked at Bai Chen in surprise.

"This is going to talk about aerodynamics, do you understand?" Bai Chen glanced at Lan Xuan with a sneer.

"What aerodynamics?" Lan Xuan wondered in his heart, could it be that there was still knowledge in this world that he had never even heard of?

"Do you know what the bird can fly for?"

"Because there are wings. ”

"Forget it, play the piano to the cow. Bai Chen smiled and shook his head.

Bai Chen's words were undoubtedly an unforgettable humiliation for Lan Xuan.

"Bring a piece of rice paper. "Origami airplanes, apparently no one here has ever done that.

In fact, the paper in this world is still quite precious, Bai Chen took a piece of rice paper with exquisite workmanship to fold, in the eyes of everyone, it was a waste at all.

Bai Chen threw it lightly, and threw the folded paper airplane out, and the paper airplane circled in mid-air for a while, and fell in front of everyone flutteringly.

Everyone watching was shocked for a while, and they all looked at Bai Chen in disbelief.

"This is?" Lan Xuan picked up the paper airplane and threw it again: "This piece of paper can fly?"

"It can't fly, but it can glide, and it's a very simple principle, and whether it can fly high in the sky, but it's not about aerodynamics today, so I don't want to waste my words. ”

Bai Chen glanced at Lan Xuan: "Are you satisfied with my answer just now?"

Lan Xuan nodded: "There was once a person who said that this world is round, but I can't tell the reason. Lan Xuan looked at Bai Chen: "Your answer today has solved my confusion for many years, this question is considered your correct answer, so let's ask questions." ”

"Do you know what the moon is and what it will shine?" Bai Chen asked.

Lan Xuan asked about geography, which was well documented, but Bai Chen didn't believe that Lan Xuan knew the astronomical knowledge.

"It already glows, what's there to argue about?" Lan Xuan frowned, as if some ordinary creature could glow. Do you still need to get to the bottom of it?

"No, no, no...... The moon doesn't shine, and this question is related to the question I just answered you. ”

Lan Xuan's brows furrowed, and he looked at Bai Chen angrily: "Okay, even if I don't, if you can tell the basis, this question will be regarded as my loss." ”

"Quite simply, the moon shines because of the sun's rays. ”

Bai Chen said with a smile, and Lan Xuan snorted coldly: "Nonsense." The moon appears at night. The sun appears during the day, so how does the sun's rays shine on the moon?"

"Ignorance. Bai Chen spat lightly, and his eyes couldn't help but show contempt.

With this knowledge, you dare to debate astronomy and geography with me?

There are more elementary school students on the earth who know the Tao than you......

"Close the door. Close the curtains. Bring another candle over here. ”

Lan Xuan didn't know what Bai Chen planned to do. Still, he commanded others to do so.

"For example, this lamp is the sun, and this teacup is our worldly realm, and we will call it the earth for the time being. And then this elixir is the moon, the earth where we are, in fact, revolves around the sun, and then there is the moon, which is the satellite of the earth, which revolves around the earth, and the earth itself is also rotating, which is also for what Sometimes the moon is in the right space, sometimes it hangs obliquely, if we are on this side of the teacup, if the moon turns here, the earth blocks the sun, the moon loses its light source, so it causes a lunar eclipse, and if the solar eclipse ......"

The scene was silent, and he looked at Bai Chen dumbfounded.

What Bai Chen said, they had never heard of, but Bai Chen could state it reasonably.

Answer all the questions of everyone one by one.

"Do you know that the sun is round and the moon is round, and what can't the earth be round?"

"This ......"

"In fact, in astronomy, the sun is called a star, the earth is called a planet, the moon is called a moon, and there are gold, wood, water, fire, earth, and ......."

Bai Chen continued to explain simple astronomical knowledge, even if everyone couldn't believe it, but in the face of the accurate and detailed answers given by Bai Chen, they couldn't help but believe it.

Perfect answer, and the second question is closely tied to the first question.

Lan Xuan was convinced, and in the third game, he lost again......

However, Lan Xuan did not admit defeat immediately, but asked a few more questions.

Of course, this is not a continuing challenge, but a solution to the doubts in the mind.

Perhaps, only in him, can the answer be obtained.

Lan Xuan thought in her heart, although she was very unwilling, but she had to admit that the answer given by Bai Chen was more in line with what she had in mind, and even more detailed, more complete, and more reliable than the records in the classics she had seen.

"How do you know so much?" Qu Zhishui looked at Bai Chen suspiciously.

This is definitely not Bai Chen's speculation, the answer given by Bai Chen is very rigorous, rigorous enough to overturn any hypotheses and conjectures.

"Seeing is believing, hearing is false. ”

"You said you could see the stars?" everyone was shocked, and Lan Xuan's eyes were even more surprised and expectant.

"If you can, you can see it. ”

Bai Chen's noncommittal answer made everyone feel that Bai Chen must have a way to see it.

"What conditions are you talking about?"

"My master once created a telescope that could see hundreds of millions of miles away, and even the stars could see clearly, and when the eyes saw it, many secrets were no longer secrets. ”

"Who is your master?"

Everyone was shocked in their hearts, a disciple who could teach this kind of knowledge, so how terrifying was his teacher's knowledge?

In everyone's mind, all of them portray the appearance of a hidden master, with fairy wind and bones, food and drink, just like a person among the gods.

Amazing, this is the thought in everyone's mind.

"Can't say...... I can't say ......," Bai Chen shook his head mysteriously.

Yes, this kind of reclusive master definitely doesn't want others to disturb him.

Otherwise, with his talent and learning, he would have already become famous all over the world, why is his reputation not obvious.

"This game...... I lost, and in the next game, you have a problem. ”

Three rounds! Lose three games in a row!

There are still three games, Lan Xuan gritted his teeth, he must not lose!

Even if you lose one more game, you will lose face.

An inexplicable smile appeared on Bai Chen's face, and Lan Xuan's heart trembled.

Damn, what the hell is going to make it difficult for me?

Lan Xuan hated Bai Chen at the moment, and it was because he was too light on the enemy that he would fall into trouble.

Now the topic he came up with must be quite unfavorable to himself.

"Fourth Game ......" (to be continued......
