Chapter 335 Leading the Audience

But when Zhang Hao heard that Hongxuanzi wanted to listen to the 'Circle of the Earth', Zhang Hao's eyes suddenly brightened—this was an opportunity, an opportunity to add points for himself!

Compared with Xuanzhen Sect, I don't have any disadvantages, but I also have many advantages. For example, understanding of the world! Now that he has the opportunity to make himself a "long story", Zhang Hao certainly cannot miss the opportunity.

So Zhang Hao started with Kuodixiang first.

It is said that Zhang Hao made a simple inference based on various legends and records on the Kuodixiang just after he got the Kuodixiang, and today Zhang Hao made this inference again and started the topic with this.

"At that time, my disciples thought that the Continent of Formation in the north is frozen all year round. It is said that the sun in the Continent of Formation is very low, which is completely different from ours. Then they must receive very little sunlight, at least less than ours.

Then there is the Continent of Hidden Earth in the northeast, where the sun even sticks to the horizon, and it is often plunged into darkness. What is the reason for this?

Comparing it to the Land of Earth, it is said that the sun is shining and the heat waves are rolling there, and the disciple suddenly realized.

There is only one explanation that can cause this phenomenon—the earth is spherical! "

As he said that, Zhang Hao used magic as a demonstration. First, he condensed a one-meter-long ice ball and placed it on the ground. The positions of the seven continents were simply drawn on the ice ball, and then he condensed a fireball from a distance as the sun, which was far away. The light flickered, the puck spun slowly, and a wonderful scene appeared.

But what needs to be pointed out here is that Zhang Hao consciously tilted the rotation axis of the planet at this time, and it is the planet that rotates, not the sun that revolves around the planet.

Why do you do this? This may be a subconscious move. After knowing what is going on, people will have an instinct to pursue the truth.

But after Zhang Hao did this, the problem appeared again.

"Why doesn't the sun revolve around us?" Hong Yuanzi said, "The sun in the sky is so small, and the earth under our feet is so huge, but according to our usual observation, it should be the sun that revolves around us!"

"This..." Zhang Hao scratched his head, "I don't know if there are any astrologers in the Xuanzhen Sect? According to the analysis of astrologers' data, Zhao Dahe believes that including our planet, there are five stars of 'gold, wood, water, fire, and earth' They all revolve around the sun, so that many problems can be explained. (Note ①)

As for saying that the sun is very small, that is an illusion. According to Zhao Dahe's calculations, the size of the sun... is very likely to be tens of thousands of times the size of our Tianyuan star. And the reason why it looks very small is because the sun is very far away from us!

I have a way to prove this! "

"How to prove it?" Headmaster Hong Xuanzi asked.

"Sunshine is parallel!" Zhang Hao first threw out a concept, and then began to explain. If a small fireball shines, its light must have an included angle. Unless it is a wall or a vertical surface that emits light, its light is parallel and has no included angle.

But the light shining on Tianyuan star has no included angle (the weak included angle is difficult to measure).

This is a simple test that can be done on the spot. Everyone was busy and suddenly stopped talking. If this is true, then the sun in the sky should be larger than imagined.

It was the first time for astronomy to be revealed in front of everyone; and Zhang Hao regarded astronomy as his own weapon.

Then Zhang Hao started his own performance, the concept of planetary rotation and one day, the concept of revolution and one year, the concept of rotation axis and ecliptic plane, and some common stars such as Polaris as evidence.

Everyone is a practitioner, especially the Xuanzhen Sect has "Little Zhou Tiangong", everyone also has a simple study of the stars, and they gradually agree with what Zhang Hao said. But gradually shocked.

Why sometimes we can't see Venus and Mars? Why does Mars sometimes go backwards? Put it on a revolution surface, everything is clear at a glance!

Young master Zhang led the audience.

The first time I came to Xuanzhen Sect, it brought a huge shock to Xuanzhen Sect.

After a long time, the head teacher of Xuanzhen Sect finally sighed, "What about the moon? You've been talking about it for a long time, but you didn't even mention the moon!"

"Because the moon revolves around us! It is also the only planet that revolves around us that has been observed so far. One revolution of the moon is one month, and we have made a lunar calendar based on the rotation time of the moon.

In addition, the moon itself does not emit light, it reflects the light of the sun; the change of the moon phase also shows that our earth and the moon in the sky are spherical..."

Zhang Hao used two ice hockey balls, one big and one small, plus a fireball to demonstrate the changes of the moon phases, even including lunar and solar eclipses!

Finally, Zhang Hao said: "At present, according to Zhao Dahe's measurement and calculation, the diameter of our Tianyuan star is about 128,700 kilometers. As for the moon and the sun, because the distance is too far, there is no way to measure it yet."

"Oh... oh..." All the masters of the transformation stage nodded in unison. Zhang Hao explained that he had already conquered all the masters without knowing it. Zhang Hao may not be able to tell some details, some calculation data and process, etc., Zhang Hao did not say; but the derivation process, various evidences, etc., Zhang Hao said clearly.

As for the people in the hall, I don't know when it has exceeded two hundred, and many Nascent Soul Stages have come in.

Suddenly, Zhang Hao's ancestor Hong Yunzi took the lead in applauding, "Okay, very good! Zhang Hao, you are the pride of Xuanzhen Sect. It is also the luck of Xuanzhen Sect to accept you as a disciple!"

Zhang Hao looked at this master, with gratitude in his eyes. Hong Yunzi's words carry a lot of weight, and they give Zhang Hao a certainty—this disciple is not simple, Xuanzhen Sect should cherish it!

Yes, it's not easy. Everyone nodded slowly, this insight is no small matter - in the world of practice, the understanding of heaven and earth is very important!

However, after solving the problem of the theory of the circle of the earth, there is a new problem - where is the 'sky'? What happened to the Heavenly Tribulation during the Transcendence Tribulation? Where is the fairyland? Could it be that Feisheng went to the moon?

In the past, in practice, I have always paid attention to the way of heaven. The theory of the circle of the earth has caused a great impact: where is the 'sky'? What is the way of heaven that we practice? What is the usual swearing?

So for a while, no one asked about Zhang Hao's voyage, and everyone started arguing about the practice again.

After a while, Zhang Hao said cautiously: "Well... I can probably explain Heavenly Tribulation."

Swish! Everyone's eyes fixed on Zhang Hao.

Zhang Hao took a deep breath, "Teacher, this may involve some secrets. I can say that there is no requirement. But I think this secret should not be passed on outside."

Hong Xuanzi nodded: "Don't worry, everyone present is reliable. If news spreads from Xuanzhen Sect in the future, I will personally apologize to you!"

"No, no, no..." Zhang Hao hurriedly waved his hands, "Master, my father had a catastrophe when he transformed into a baby before. With my father's cultivation and foundation, he couldn't resist it at all.

At that time, when I had an idea, I used iron pillars, iron cables, iron fences, etc. to block my father's side and head. As a result, the lightning hit the ground along the iron chain.

In the end, the iron chain partially melted, but my father was successfully transformed into a baby.

Even after the catastrophe, my father's foundation became more stable, and he surpassed Liu Jingming, the governor of Ninghe County at that time, and Liu Jingming had already broken through for more than ten years.

Later, Liu Dingshan, the Supreme Emperor of the Kingdom of Qixia, broke through to the late stage of transformation by the sea and caused a catastrophe again. We still used this method to prevent him from catastrophe. Since then, Liu Dingshan's cultivation base and foundation have also been strengthened unprecedentedly. "

At this time, Hong Zhenzi, the head of the Law Enforcement Hall, said: "I have been in contact with Liu Dingshan, and his foundation is not at all as if he just broke through, it is very solid. I think it is the credit of Heavenly Tribulation!"

When Makoto Hong spoke, everyone looked at Zhang Hao brighter. The head teacher, Hong Xuanzi, was even more surprised and asked, "What is the reason?"

Zhang Hao said slowly: "Teacher, I'm just guessing. I think that the catastrophe is actually a natural phenomenon, just like thunderclouds in the sky. When a practitioner breaks through, it will attract a lot of spiritual energy. These The auras will rub against each other, perhaps forming an effect similar to thunderclouds in the sky.

But like rain clouds in the sky, not all rain clouds make thunder. And the practice is the same, not everyone will cause a catastrophe.

However, judging from the current situation, the catastrophe is not a punishment, but an opportunity. After being tempered by the Heavenly Tribulation, the aura is purer and its foundation is more stable. If we can find the law and artificially control the occurrence of lightning, then for Xuanzhen Sect, we will undoubtedly get a shortcut!

According to my observation and speculation, there is a lot of water vapor at the seaside, and the combination of aura and water vapor is more likely to trigger the catastrophe!

I suggest that anyone in the sect who is preparing to transform into a baby can go to Dayang Group, where we have already made comprehensive preparations. "

The atmosphere in the hall is heavy again. Compared with the theory of the circle of the earth, astronomy, and great navigation, practice is directly related to everyone! This is a real vital interest, and we cannot help but pay attention to it!

After a while, the head teacher Hong Xuanzi asked Zhang Hao in amazement: "How sure are you that the catastrophe is a natural phenomenon? Or is it a chance?"

"Ten percent!" Zhang Hao said firmly! At critical moments, there is no room for hesitation! At this time, Zhang Hao's expression was serious and serious, and his words were firm and decisive. The demeanor of the president bloomed on Zhang Hao.

Hong Xuanzi looked at Zhang Hao, what he saw at this moment was not an ordinary disciple, but... the president of Dayang Group!

Hong Xuanzi was amazed, he had a comprehensive understanding of this disciple who hadn't climbed the mountain gate for almost a year after his apprenticeship. Indeed, as Hong Yunzi said, Xuanzhen Sect is lucky to have a disciple like Zhang Hao!

The theory of the circle of the earth, great voyages, astronomy, and this catastrophe, let Hongxuanzi see the future of Xuanzhen Sect.

However, after being amazed, Hong Xuanzi still spoke, but his tone was soft, and he said in an almost equal gesture: "Zhang Hao, there is one more thing to discuss with you today, and I think you have guessed it. That is: Navigation , Battleship!"

(It's almost the end of the month. If you have a monthly pass, hurry up and get it. The monthly pass is valid for the month and does not accumulate.)

(Note ①: The astronomical setting is going to copy the solar system, everyone is familiar with it, and it is convenient to write. And some brain holes about the moon will also be written here.

Some of the unfinished parts of "Half Immortal Civilization" will be perfected here. )
