Ganing and his party spent nearly ten days detouring to Australia, but before that Lu Bu had sent Chitu back to Diao Chan for safety.

So when Gan Ning and his party sent Lu Bu back, Diao Chan was standing on the coast and waiting for Lu Bu's return.

"Hi, so beautiful!" Sun Ce looked at it decisively and turned his head, why Ma Chao was chased by Lv Bu for thousands of kilometers, he still knows, Chitu and Diao Chan, that can't be touched.

"Fengxian, are you okay?" Lu Bu embraced Diao Chan in his arms without much talk, Diao Chan asked timidly.

Although there are countless words I want to ask, why do I come back so long, I wondered how Lu Bu suffered multiple injuries, and whether Lu Bu ’s hidden troubles were eradicated, but when he saw Lu Bu, Diao Chan only asked such a sentence words.

"It's okay, don't worry, no one can beat me. After a while, let's go back to the Central Plains." Lu Bu said quietly, and didn't say anything bad about Zhao Yun and Lu Qiling, but the hand holding Diao Chan shivered.

"Well, go back to the Central Plains." Diao Chan looked up and saw Lu Bu nodded with a smile that warmed Lu Bu's heart, and did not resist Lu Bu's worry.

It was only at that moment that Diao Chan held Lu Bu's hands, and his fingers could not help twisting together behind Lu Bu. Zhongyuan, who buried his own uncle and buried the place where he used to go?

Even if he is his strongest and invincible husband, he ca n’t be absolutely stable in the Central Plains. When he returns there, his husband wants to set foot on the road to conquer Central Plains, but he ca n’t tie him to his side forever. Hawk, although he fell to the earth for a while, his real residence has never changed, that is the sky!

"Well, go back to the Central Plains." Diao Chan looked up at Lu Bu gently, even if the goshawk fell on the ground because of his favorite things, but one day he needed to return to the sky, and that was his real hometown.

"Wenhou, wait a day or two, how about I wait for the road to be refilled." Zhou Yu said politely to Lu Bu, this is really a terrible man.

"If you want to go south to the west, there is a river." Lu Bu pointed to the southwest and said casually. Soon after he moved to the west coast, he found this place with water, sea, and dense vegetation. local.

Zhou Yu nodded and ordered a large number of pawns to disembark and land. Some of the saviors who watched the heavens and earth slipped with them, but after a long time, the sergeants ran back with a look of surprise. They found the iron ore.

"You mean you found iron ore?" Zhou Yu looked at these servants slightly puzzled.

When Zhou Yu headed south, he brought a lot of comrades who were good at Feng Shui stargazing. Of course, it was not mainly for them to look for iron ore. It was mainly because of this group of people stargazing to determine their position when sailing.

Although in the southern hemisphere, the astrology of the Central Plains is dead, but Zhou Yu ’s boat speed is not very fast after all. This group of people are observing and verifying. Although the astrology is constantly changing, but through years of research on astrology By reference to the endless sleepless reference, they have now drawn some of the astrology of the southern hemisphere.

But the biggest problem now is not the astrology, but the collision of internal thinking among the group of stargazers. How to say, most of them have suspected that the thing under their feet is not flat, well, it is not a flat problem , A ball underfoot!

Although as early as sixty or seventy years ago, some people in the Central Plains had made the speculation that "the sky is like a chicken, the celestial body is like a projectile, and the ground is like a chicken in yellow", but there were not too many people who believed.

But the question now is based on the conclusions drawn by this group of stargazing guys, either the stars in the sky are very close to us, or the thing under our feet is a ball.

Because only when the object is very close, you will feel that you are moving, the object moves to another place, and when something is far away, basically you move again, and the other party ’s perceptible displacement does not exist. .

In ancient China, the distance between the earth and the moon was calculated based on this method. Although there is no accurate way to measure displacement and inclination, the error is very large, but the method is not wrong.

In this case, in fact, all stargazers know that the distance between the moon and them is hundreds of thousands of miles, and according to the results of their boat trips, the stars can only be closer to the moon to cause this displacement, but this is not the case. Maybe!

At this time, the people at the bottom of the world did not know how many stars the Beidou was. They just thought that the shape has always been like this, but the descendants of the Jiantianguan, which have been circulating for a long time, all know that the Beidou has nine stars. The continuous changes over the years are actually small changes, but this kind of change cannot be determined by non-professionals.

Of course, those who can be found by Zhou Yu must be professionals. Naturally, they all know the changes in the star map, and they enter the southern hemisphere from the northern hemisphere. The star map of the Big Dipper has not changed, and even the stars have not seen a visible offset, which is enough to explain the distance. The stars are far above the moon.

This is the most tangled place of all stargazers. The positions of the stars are not offset, but they are hidden. At that time, some of the stargazers doubted that the ground under their feet was not flat.

Later, when I was traveling on the sea, I became more and more sure. After seeing the ship in the distance on the sea and the mast in the first position, most stargazers confirmed the fact that we could not determine whether the ball was the ball. , But definitely not flat.

At this point, all the stargazers have reached a consensus, but it is of no use. The radical stargazers rely on the earth to be a ball. They have solved the problem of the lunar eclipse, and also explained that the moon blacked out during the lunar eclipse. Why the place happens to be an arc.

In short, for this almost fight, if it is a ball, why did n’t we fall, because it ’s so big, so it ’s so flat.

Then someone based on the distance between the top mast of the ship visible on the sea and the place where he stood, started to calculate how big this hypothetical situation is when a perfect ball was reached, and then a group of people almost hit again.

In short, this thing is definitely not a square piece, but what most stargazers can't understand is that if it is a ball, what should the group of guys on the back of the ball do?

After all, it's not parallels that can continue to tear with the other party in this case. Zu Shang definitely has astrology and mathematics, especially among these people, there are descendants of Gander. Although he supports this thing at his feet It was a ball, but he asked someone a question.

"My ancestor said in the Ganshi Xingjing six hundred years ago, we are turning around the sun, and now this thing under our feet is a ball according to our calculations, should we fly when we turn to the back Go out! "Gan Fen asked such a question at the time.

No one can answer this question on knees, although there are monsters like Wang Fan's dad, Chen Zhuo's grandpa, but these people have no way to solve this problem.

Although these people can use mathematics to calculate the approximate size of the earth in the form of perfect circles, radians, tangents, and trigonometric functions in the case that π is still estimated by these people, none of them can solve the Ganfen question. problem.

But although there is no way to solve this problem, this group of people did not fight, but because this thing is a ball at the foot, it has caused a split within them.

In short, this group of people is ready to go old and die, and study this after going back. If you do n’t study it, give it to your son to continue to study. The son died and there are grandchildren, anyway.

After all, most of the people who can do mathematics and astrology in ancient times are not poor people. Most of them have played all over the world. There is no more to play. They can only invest in the ocean of knowledge to make themselves feel refreshed, so for these people Say there is no such thing as difficulty and life.

There will be successors even if they die. This generation cannot be completed. The next generation will continue to study. Anyway, they will write down what they do n’t understand. When one day later, they will solve it. This is their own capital. Any mathematical problems and natural phenomena are encountered. This kind of model, which is started by generations of people who have nothing to do before they start to study, basically has no natural science to withstand.

This is especially true of a family from top to bottom, and the heirs have received this kind of nurturing from birth, and the support that the family can give from the beginning has exceeded the normal level.

The group of people who had fallen out secretly made up their minds and started to study at home. As for being on board, let's work for Zhou Yu obediently.

Although this group of people was absent-minded when they were working because of a major problem, they were all good players after all, and they didn't even forget about the skill of eating.

Then they found a super-large, extremely high-quality iron ore, and according to their experience, this iron ore seems to be better than the quality of any iron ore recorded by them!

This is a bit amazing, so a group of people hurried back to Zhou Yu to report this matter.

"Is the iron ore of excellent quality?" Zhou Yu said puzzled, not paying attention.

The Central Plains is too far away from here. The transportation alone feels very unworthy. Considering the traffic volume of the ship and the **** vessels needed to deal with the Guishuang navy that may exist in Malacca on the way, Zhou Yu said that the pressure was too great. A trip to and fro 20,000 kilometers!

If the iron ore is transported at such a long distance, the cost has already exploded. It is better to mine in the Central Plains and build a smelting site on site. Australia is too far away.

However, Gan Ning seems to be very interested in iron ore. In his view, he can not get his hands now, he can take it first, he can also take the first enclosure, and prepare the future generations since ancient times. People feel useless, so they don't give way to future generations.
