Mythic version of the Three Kingdoms

Chapter 2160 It's a Ball

It took Gan Ning and his party nearly ten days to make a detour to Australia, but before that, Lu Bu had already sent Chitu back to report Diaochan's safety.

So when Gan Ning and his party sent Lv Bu back, Diao Chan was standing on the shore quietly waiting for Lv Bu to return.

"Hiss, so beautiful!" Sun Ce took a look and turned his head decisively. He still knew why Ma Chao was chased by Lu Bu for thousands of kilometers. Chitu and Diaochan must not tease him.

"Fengxian, are you okay?" Lu Bu hugged Diao Chan into his arms, without saying much, Diao Chan lowered her head and asked timidly.

Although there are countless things I want to ask, I want to know why it took me so long to come back, I want to know how many injuries Lu Bu suffered at that time, and I want to know whether Lu Bu's hidden dangers have been eradicated, but when seeing Lu Bu, Diao Chan only asked this question talk.

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

"Well, let's go back to the Central Plains." Diao Chan looked up at Lu Bu and nodded with a smile that warmed Lu Bu's heart, without the resistance that Lu Bu was worried about.

Just at that moment, Diao Chan hugged Lu Bu's hands, and her fingers couldn't help but twisted together behind Lu Bu's back. Central Plains, will the place where she buried her adoptive father and her past eventually return?
Even if my strongest and invincible husband is still not absolutely safe in the Central Plains, when he returns there, my husband wants to embark on the road to conquer the Central Plains again, but I can't tie him by my side forever, he is a hero. Eagle, although he fell back to the earth for a while, his real abode has never changed, which is the high heaven!

"Well, let's go back to the Central Plains." Diao Chan raised his head and looked at Lu Bu gently. Even if Goshawk fell to the ground because the things he liked were on the ground, one day he needs to return to the sky, which is his real hometown.

"Marquis Wen, wait for a day or two, how about I wait for the drinking water to be replenished before going on the road." Zhou Yu said to Lu Bu respectfully, this is really a very scary man.

"Whatever you want, go to the south west, there is a river there." Lu Bu pointed to the direction of the southwest and said casually. Not long after he moved to the west coast, he found this place with water, close to the sea, and dense vegetation. place.

Zhou Yu nodded, and ordered a large number of soldiers to disembark and land. Some fortune tellers also slipped down, but after only half a day, those fortune tellers came back with a look of surprise. They found iron ore.

"You mean you found iron ore?" Zhou Yu looked at these physiognomists with a little puzzlement.

When Zhou Yu went south, he brought a lot of fortune-tellers who were good at geomantic omen and stargazing. Of course, he did not mainly ask them to look for iron ore, but mainly relied on these people to determine the direction when sailing.

Although astrology in the Central Plains is dead after arriving in the southern hemisphere, Zhou Yu’s boat speed is not very fast after all. This group of people are observing and verifying at the same time. Although the astrology is constantly changing, relying on years of research on astrology , relying on sleepless reference comparisons every night, they have now drawn part of the stars in the southern hemisphere.

But the biggest problem now is not the astrology, but the collision of thoughts among the group of stargazers. How should I put it, the vast majority of them have already suspected that the thing under their feet is not flat. , There is a ball under your feet!
Although as early as 70 to [-] years ago, some people in the Central Plains had conjectured that "the sky is like a chicken, the celestial body is round like a bullet, and the earth is like a yellow chicken", but not too many people believed it at that time.

But the problem now is based on the conclusions drawn by this group of stargazers, 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 move and the object moves to another place. When an object is far away, basically you move again, and the other party’s perceivable displacement does not exist. .

In ancient China, the distance between the earth and the moon was calculated according to this method. Although there is a large error because there is no way to accurately measure the displacement and inclination, the method is not wrong.

In this case, all stargazers actually know that the moon is hundreds of thousands of miles away from them, and according to the results of their perception of the boat all the way, the stars can only have this displacement when they are closer to the moon, but this is not true. Maybe!

At this time, the people at the bottom didn't know how many stars the Big Dipper was, and they just thought that the shape had always been the same, but these descendants of the Tianjian officials who have been passed down for a long time, all know that the Big Dipper has nine stars. The continuous changes over the years actually have 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 when they entered the southern hemisphere from the northern hemisphere, the star map of the Big Dipper did not change. The stars are farther than the moon.

This is the most tangled place for all stargazers. The position of the star map of the stars has not shifted, but they have disappeared. At that time, some of the stargazers suspected that the ground under their feet was not flat.

After traveling on the sea, it became more and more certain. After seeing the ship in the distance on the sea surface and the mast at the first position, most stargazers have confirmed the fact that we have no way to determine whether it is a ball or not. , but definitely not flat.

All the stargazers have reached a consensus on this point, but it is useless. The radical stargazers, relying on the earth as a ball, have solved the problem of the lunar eclipse, and also explained that the moon blacks out during the lunar eclipse. Why is the place exactly an arc.

In short, we almost got into a fight because of this. If it was a ball, why didn't we fall, because it is big, so it looks flat.

Afterwards, someone started to calculate the size of the hypothetical perfect ball based on the distance from the topmost mast of the ship visible on the sea to where he was standing, and then a group of people almost fought again.

In short, the thing under the feet is definitely not a square piece, but what most stargazers can't understand now is if it is a ball, what about the group of guys on the back of the ball?
After all, those who can continue to fight with each other in this situation are not parallel imports. There must have been masters in astrology and mathematics in the ancestors, especially the descendants of Gander among this group of people. Although he supports this thing under his feet It was a ball, but he asked the others a question.

"My ancestors said 600 years ago in the Ganshi Almanac that we are revolving around the sun, but now the thing under our feet is a ball according to our calculations. When we turn to the back, should we fly out? !” Gan Fen asked such a question at that time.

The audience knelt down, and no one could answer this question. Although there were monsters like Wang Fan's father and Chen Zhuo's grandfather, none of them could solve this problem.

Although these people can use mathematical methods to calculate the approximate size of the earth in the form of perfect circles, radians, tangents, and trigonometric functions when the π is estimated by them, none of them can solve the problem Gan Fen asked. question.

However, although this group of people did not fight because there was no way to solve this problem, but because the thing under their feet was a ball, they had already split inside.

In short, this group of people is ready to stay away from each other until they die. They will study this after they go back. If they die, they will leave it to their sons to continue researching. After the son dies, there will be grandchildren.

After all, in ancient times, most of those who could do mathematics and astrology were not poor people. Most of them had played all over the world. Say there is no difficulty and live with this problem.

Even if it dies, there will be successors. If this generation can’t complete it, the next generation will continue to study. Anyway, write down what you don’t understand, and when future generations solve it, this is your own capital. Any mathematical problems and natural phenomena encountered This kind of model, where generations of people start researching when they have nothing to do, is basically not able to withstand the natural sciences.

This is especially the case in a family from top to bottom, and the heirs receive this kind of edification as soon as they are born. From the very beginning, the support that the family can give exceeds the normal level.

The group of people who fell out secretly made up their minds, and started researching when they got home. As for now on the boat, they should obediently work for Zhou Yu.

Although this group of people were a little absent-minded when they were working because they discovered a major problem, they were all good at it after all, and they didn't even forget the technique of eating.

Then they discovered a super-large iron ore with extremely high quality, and based on their experience, this iron ore seemed to be of better quality than any iron ore they had recorded!
This was a bit surprising, so a group of people rushed back to report to Zhou Yu.

"Excellent iron ore?" Zhou Yu asked in confusion, but didn't take it seriously.

The Central Plains is too far away from here, and the transportation alone feels very unworthy. Considering the volume of the ships, and the escort ships needed to deal with the Guishuang Navy that may pass through Malacca on the way, Zhou Yu said that the pressure is too great. A trip back and forth might be [-] kilometers!

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

However, Gan Ning seems to be very interested in iron ore. In his opinion, if he can’t get it now, he can also occupy it first. People think it's useless, so they won't give future generations a living.

　In other words, it's really a hell, I've been updating it this month, but my subscription is not as good as last month...
