Kou Zhong said: "Big brother hasn't explained yet, why can you travel 80,000 miles a day standing still!"

Huang Yi smiled: "Because the earth is round! That's why there is a day and night change. So here we stand and don't move for a day. In fact, the Earth has already come full circle. ”

Several of them were very smart people, and they immediately understood. Ba Feng said coldly: "Big brother is saying...... The sun hasn't moved? In fact, the earth has been moving since day and night.

Huang Yi shook his head and said, "You can't say that! The sun also has its own trajectory. It's just that it's too far away from us, and we can't see the change. The Earth's orbit is elliptical, and the Sun is at one focal point of the ellipse. The average distance of the Earth from the Sun is ...... Well, 300 million miles. ”

"What!" several people exclaimed! Ba Feng said coldly: "Actually, it doesn't mean to ride the fastest BMW in our prairie. Day and night, it would take thousands of years to reach the sun at the fastest speed?"

Huang Yi nodded in acquiescence.

Kou Zhong said, "This is amazing! It's so far away...... We can still see it. ”

Huang Yi smiled: "Because it's too big." And it glows! The earth we live on is big enough, isn't it? The sun is 1.3 million times the size of our earth. ”

Zhan Xiaomin asked, "What about the moon?"

"Yes!" Huang Yi thought for a moment and said, "The moon is smaller than the earth, but it is the closest of all the planets. The Earth is about forty-nine times the size of the Moon. ”

"Wait, wait! I have a question. Kou Zhong shouted, "Big Brother just said that the Earth's orbit is elliptical. What is revolution?"

"The earth itself rotates once for a day, but at the same time it revolves around the sun. Going around in a circle like this is called a revolution, which is our year! Because the angle of receiving irradiation is different, there are four seasons of spring, summer, autumn and winter. The temperature is also jet-lagged!" Huang Yi explained.

"It's amazing!" Kou Zhong exclaimed, "The moon revolves around the earth, and the earth revolves around the sun. No wonder sometimes I can see the sun and the moon together. ”

Huang Yi nodded and said, "That's right." Because the moon is constantly revolving around the earth. The moon orbits the earth every month, so there is a synod and a helix once a month. During the half month from the new moon to the moon, the moon is on the east side of the sun and appears in the sky before sunset, and for half a month from the new moon to the new moon, the moon is on the west side of the sun and remains in the sky after sunrise. ”

That is to say, the moon in the second half of the moon does not set below the horizon until after sunrise. Therefore, the phenomenon of "the sun has not set, the moon has risen" always occurs in the first half of the month, and the phenomenon of "the sun has risen, the moon has not set" always occurs in the second half of the month. There are also special astronomical phenomena. For example, when the moon blocks the sun, it is called a solar eclipse! It's the Tengu Eclipse Day!"

"What about the dog eating the moon that day, the sun can't block the moon, right?" asked Kou Zhong again.

Huang Yi shook his head and explained: "The moon itself does not shine. We see the moon so bright because of the reflection of the sun's rays on the moon. A shadow appears on the Earth in the direction of the Sun with its back, called the Earth's shadow. The earth shadow is divided into two parts: umbra and penumbra. The umbra refers to the place where it is not exposed to direct sunlight, while the penumbra is only partially exposed to the sun's direct rays. The Moon sometimes enters the Earth's shadow as it orbits the Earth, which creates a lunar eclipse. A total lunar eclipse occurs when the entire Moon enters the umbra, but only a partial lunar eclipse occurs when only a portion of the Moon enters the umbra. Both total lunar eclipses and partial lunar eclipses are because the sun's rays are blocked by the earth, so they will have images such as round, missing, and lunar eclipses!"

Ba Feng smiled coldly: "Heh! Although I didn't understand it, I still gained knowledge! How did the eldest brother know so much? Even astronomy understood. This is the real knowledge of astronomy and geography!"

Huang Yi smiled: "I still know 500 years ago, and 1,000 years later......!"

Everyone thought he was joking.

Huang Yi said: "Some things have been confirmed. For example, the earth is round. In all directions, you can choose that path and go straight. With your martial arts, you only need to move forward during the day. Rest for the night!At most a year or so, I promise you'll come back to this place!"

"Heh!" Kou Zhong laughed, "I always thought that the earth was endless. Since it has an end, then I'm going to fight for it all. I want to truly unify the world! Do what Qin Shi Huang failed to do!"

"Bah!Ziling, what's wrong with you?," Bai Fenghan asked.

Xu Ziling said: "Although I didn't speak. But kept listening. For the big brother said that the earth is round, and it may be able to complete a circle in about a year. I'm really yearning. When Zhong Shao has a team, I may have to leave. Go on a circumnavigation of the globe. ”

Huang Yi smiled: "How can it be so easy. Out of the Central Plains, you don't even understand their language. ”

"Maybe there will be a way in the future!" Xu Ziling said: "I was just thinking, why did the energy of He Shibi finally reach his sister-in-law, and when he rolled back, why did it suddenly change?"

Huang Yi said: "This should be the true harmony of yin and yang, although my demonic qi and Kou Zhong's true qi are both negative. But in fact, we are all men who are yang, and Xiaomin is the only woman. It is the conformity of the negative. That's why yin and yang are neutralized. This strange energy that fluctuates from heat to cold is changed. By the way, how did you receive the goods?"

Ba Fenghan closed his eyes excitedly and said, "The inner and outer heaven and earth seem to be blended together. It's an indescribable feeling!"

The other three immediately nodded in agreement.

Xu Ziling nodded and said, "It seems that the world has changed." It's like Zhong Shao and I just learned the recipe for growth. I feel like we've not improved much. But in fact, we've taken it up a notch. This is a qualitative change. ”

Huang Yi asked, "What about the meridians?"

Several people were reminded by Huang Yiyi, and immediately looked inward! Almost at the same time, they couldn't help but be surprised: "It's a lot." Some places that were originally inoperable have been unimpeded. ”

Huang Yi smiled: "Congratulations, congratulations! Haha, I also opened Sun Luo!"

There are 12 meridians in the human body, and there are 365 Sun meridians, and their blood and qi are all on the face, and they walk on the holes.

"Big brother is the biggest recipient! However, he is also the most adventurous person. Kou Zhong sighed and said, "The He clan is gone, only Yang Gong's treasure house is left! I have to think about it now, how to start implementing my plan to dominate the world!"

"it!" a few scolded, "Now give me a good idea of where to find a clean and clear river." Wash the smell off my body!" )
