Gan Ning and his party spent nearly ten days taking a detour to Australia, but before that Lu Bu had already sent Red Rabbit back to assure Diao Chan that he was safe.
So when Gan Ning and his party sent Lu Bu back, Diao Chan was standing on the coast quietly waiting for Lu Bu to return.
"Hey, so beautiful!" Sun Ce took one look and turned around decisively. He still knew why Ma Chao was chased by Lu Bu for thousands of kilometers. Red Rabbit and Diao Chan must not be flirted with.
"Fengxian, are you okay?" Lu Bu hugged Diao Chan into his arms and didn't say much. Diao Chan asked timidly with her head buried in the air.
Although she had countless questions to ask, wanted to know why it took so long to come back, wanted to know how badly Lu Bu was injured at that time, wanted to know if Lu Bu's hidden dangers had been eradicated, but when she saw Lu Bu, Diao Chan only asked this question.
talk.
"It's okay, don't worry, no one can defeat me. Let's go back to the Central Plains after a while." Lu Bu said calmly. He didn't say anything bad about Zhao Yun and Lu Qiling, but his hand holding Diao Chan was shaking a little.
"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.
But at that moment, Diao Chan held Lu Bu's hands, and her fingers couldn't help but twist together behind Lu Bu's back. Central Plains, will the place where her foster father and her past be buried finally return?
Even her strongest and invincible husband cannot be absolutely stable in the Central Plains. When he returns there, his husband will embark on the road of conquering the Central Plains again, but he cannot tie him to his side forever. He is a hero.
Even though the eagle fell back to the earth for a while, his real residence has never changed, which is the sky above!
"Well, let's go back to the Central Plains." Diao Chan raised her head and looked at Lu Bu gently. Even if the goshawk falls to the earth because the thing he likes is on the earth, one day he will need to return to the sky. That is his true hometown.
"Marquis Wen, how about waiting for a day or two while I resupply the drinking water before setting off on the road." Zhou Yu said to Lu Bu respectfully. This was really a very scary man.
"Whatever you want, walk to the south-west, there is a river there." Lu Bu pointed to the southwest and said casually. Soon 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 who were observing the sky and the earth also slipped down. However, within half a day, the fortune tellers came back with a look of shock on their faces. They discovered iron ore.
"You mean you discovered iron ore?" Zhou Yu looked at these fortune-tellers with some confusion.
When Zhou Yu went south, he brought with him many fortune tellers who were good at Feng Shui and stargazing. Of course, the main purpose was not to let them look for iron ore, but mainly to rely on these people to determine the direction of the ship by stargazing.
Although astrology in the Central Plains has died after arriving in the southern hemisphere, Zhou Yu's sailing 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 many years of research on astrology
, relying on reference comparisons every night, they have now drawn some of the stars in the southern hemisphere.
But the biggest problem now is not the astrology, but the collision of thoughts within this group of stargazers. How should I put it? Most of them have already suspected that the thing under their feet is not flat. Well, it is no longer a question of whether it is flat or not.
, there is a ball at your feet!
Although as early as 60 or 70 years ago, some people in the Central Plains came up with the conjecture that "the sky is like a chicken's egg, the celestial bodies are round like pellets, and the earth is like a yellow chicken inside", not many people believed it at that time.
But the problem now is that according to the conclusion 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 if the object is very close, you will have the feeling that you are moving and the object is moving to another place. When an object is far away, it is basically you who move, and the other party's perceptible displacement does not exist.
.
Ancient China once calculated the distance between the Earth and the Moon based on this method. Although the error was large because there was no accurate way to measure displacement and inclination, the method was not wrong.
In this case, actually all stargazers know that the moon is hundreds of thousands of miles away from them, and according to the results of their boat trip, this kind of displacement can only occur if the stars are closer than the moon, but this is not true.
It's possible!
At this time, the people at the bottom didn’t know how many stars there were in the Beidou, and they just thought that the shape had always been like this. However, the descendants of the Supervisory Officials, who had been circulating for a long time, all knew that the Beidou had nine stars. To be precise, the star map has changed over hundreds of years and thousands of years.
After many years of constant changes, there are actually slight changes, but this kind of change cannot be determined by non-experts.
Of course, those who could be found by Zhou Yu must be professionals, and 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, and even the stars did not shift visible, which is enough to explain the distance.
The stars above are farther than the moon.
This is the most tangled place for all stargazers. The positions of the stars in the star map have not shifted, but they have disappeared. At that time, some of the stargazers suspected that the ground under their feet was not flat.
When it became increasingly clear when traveling on the sea, after seeing the ship in the distance on the sea and the mast at the first position they saw, most stargazers have determined the fact that we cannot determine whether it is a ball or not.
, but it is definitely not flat.
All stargazers have reached a consensus on this point, but it is of no use. Radical stargazers have solved the problem of lunar eclipses by relying on the fact that the earth is a ball, and have also explained the darkening of the moon during lunar eclipses.
Why is the place just an arc?
Anyway, we almost had a fight over this. If it was a ball, why didn't we fall? It was because it was big, so it looked flat.
Then someone started to calculate how big the ball would be if it were a perfect ball, based on the distance between the top mast of the ship visible on the sea and where he was standing. Then a group of people almost started fighting again.
In short, the thing under your feet is definitely not a square piece, but what most stargazers can't understand now is that if it is a ball, what about the guys on the back of the ball?
After all, anyone who can continue to quarrel with the opponent in this situation is not a parallel import. There are definitely great masters in astrology and mathematics in our ancestors, especially among this group of people there are descendants of Gander. Although he supports this thing at his feet
It was a ball, but he asked someone else a question.
"My ancestors said in the Ganshi Star Book six hundred years ago that we are revolving around the sun. But now according to our calculations, the thing under our feet is a ball. When we turn to the back, should we fly?
Get out!" Gan Fen asked this question at that time.
The whole 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 these people could solve this problem.
Although these people can use mathematical methods to calculate the approximate size of the earth using perfect circles, radians, tangents, and trigonometric functions when π has been 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, the fact that the thing under their feet was a ball had already divided them internally.
In short, this group of people are ready to not interact with each other until they die. They will study this after they go back. If they die and have not finished the research, they will leave it to their sons to continue to study. After their sons die, they will still have grandchildren. Anyway, there will be endless generations of descendants.
After all, in ancient times, most people who could do mathematics and astrology were not poor people. Most of them had played all over the world. There was nothing left to play. They could only plunge into the ocean of knowledge to make themselves happy again. So for these people
Say there is no such thing as difficulty and life.
Even if you die, there will be a successor. If this generation cannot complete it, the next generation will continue to study. Anyway, write down what you don’t understand. When one day, future generations will solve it, this will be your own capital. Any mathematical problems or natural phenomena will be encountered.
This kind of model, in which generations of people start research whenever they have something to do, is basically not something that natural science can withstand.
This is especially true for a family from top to bottom. Children receive this kind of influence from the moment they are born. From the very beginning, the support the family can provide exceeds the normal level.
The group of people who had fallen out each secretly made up their minds to start research when they got home. As for now on the ship, they should just work for Zhou Yu obediently.
Although this group of people were a little absent-minded when working because they discovered a major problem, they were all good at it after all, and they would not even forget their eating skills.
Then they discovered a very large, extremely high-quality iron ore, and based on their experience, this iron ore seemed to be of better quality than any other iron ore they had recorded!
This was a bit shocking, so a group of people hurried back to Zhou Yu to report the matter.
"Excellent quality iron ore?" Zhou Yu said puzzledly, but didn't take it to heart.
The Central Plains is too far away from here. Just transporting it feels very unworthy. Thinking about the shipping volume of the ships and the escort ships needed to deal with the Kushan Navy that may pass through Malacca on the way, Zhou Yu said that the pressure is too much.
A round trip may be 20,000 kilometers!
The cost of transporting iron ore over such a long distance has already exploded. It would be better to mine in the Central Plains and build a mine for smelting on the spot. Australia or something like that 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 occupy it first. If he can't occupy it, he can also enclose the land first and make preparations for future generations since ancient times. He can't do it now.
If people think it is useless, they will not give future generations a way to survive.
