When I returned home, I was naturally filled with feelings.

After crying and laughing, the family sat at the dinner table and ate a hearty meal.

As an older sister, the gentleman looked at his younger brother's half-blind eye and thought of another thing about his eyes.

After she returned from Chu Di, she now sorted out the college hall for a while. During that time, something extremely sensational happened in the college hall.

Some people blinded their eyes to explore the real reason why human eyes can see colorful things.

Because Mo Zi has a deep research on optics, he has proposed the reflection principle of eight optical methods and concave mirror convex mirrors, as well as small hole imaging and light propagation along a straight line.

Therefore, as Mo Zi's "one of the most respected disciples", of course, he had to put this skin on his body. Therefore, Si Shang had conducted spectroscopic experiments on prisms very early and a series of inventions such as telescopes related to optics.

This can be considered a kind of effect if you like something from the top. However, when it develops to a certain extent, some people really want to explore the principles of the heavenly aspirations, so all the stories that make people sigh or laugh and cry often appear in the Sutra University.

Since it is said that sunlight is essentially seven colors, and everything is black after there is no sunlight, how do people's eyes detect various colors?

So someone made a guess - the human eye is also a device like a prism.

According to the fact that the prism must have a special shape to distinguish the seven colors, and the human eyes can see the seven colors of light, so he imagined an experiment to verify whether his guess is correct.

Suppose... there is also a star shape similar to a prism in human eyes

To prove this, he first poked his eyes with his finger, that is, the part under the eye socket, and squeezed them hard, striving to deform the eyes.

After poking hard several times, I found that all kinds of fantastic colorful colors would really appear in my mind.

So to prove that he increased his strength by several points, often so that he recorded everything he had observed.

As a result, one day I used force and poked too deeply... my left eye was broken.

After it was broken, he finally came to a conclusion: the human eye is not something similar to a prism, but another reason has caused the world to be colorful. As for the reason, there is no result yet, but it definitely negates another possibility.

After this incident, the Sutra School issued a new rule - prohibiting self-harm in order to explore the truth of the will of heaven.

Because there have been several terrible situations before this, I used my own life to explore the so-called truth of the heavenly will. This time, the eye-popping incident was just the fuse of the prohibition of self-harm.

Before this, someone tried the smell of various strange ores, and recorded the feeling after taking it, and several of them were already dead.

Of course, there were also several very strange notes left behind - such as the phosphorus used by the witches and men who were poisoned to death during the Si Shang lewd sacred incident. After Soluzan returned from his journey to the west, he brought back the garlic, and some people recorded that there was a garlic smell after the phosphorus poisoning, and suspected that the garlic contained a high phosphorus content.

As for how to draw conclusions and observe them, it is another terrifying story.

This kind of thing that looks too weird outside the Si Shang or even the case outside the Sutra seems normal to people in the circle such as the gentleman.

Not to mention that Shu Guitian was blinded by his eyes, even if he drew a geographical map of mountains and rivers this time, several people died. Shu Junzi felt that it was a blessing that his younger brother could come back alive.

While drinking and chatting, the family drank a lot of wine.

The prisoner Mi looked at her brother drinking a lot of wine and was still sober, and smiled and said, "Okay, I will only drink when I leave. Now I have such a large alcohol capacity?"

Shu Guitian put down the white porcelain wine glass and said, "On the sea, we drink less and more water. The wine can be stored, but the water cannot be stored. You don't know that the merchants who went out to exchange 白 beads for gold in the South China Sea turned the sugarcane bagasse in Panyu into wine."

Looking at a plate of bean sprouts in winter on the table, Shu Guitian pointed at the bean sprouts and said, "As long as I get ashore, I won't eat a single bite of bean sprouts."

As the father, he smiled, and his mother skillfully changed the plate of bean sprouts to a place, and replaced it with a plate of vermicelli and stewed chicken.

After a few more drinks of wine, Shu Guitian looked at Shu Junzi and asked, "Sister, I have always been unable to understand how you draw the map? I look at the stars every night. I walked so far from here. All the stars in the sky are almost the same. The moon is also similar. We can calculate the latitude, how do you calculate the longitude?"

This word Jingwei naturally existed long ago, and people like Si Shang were used to it and took it for granted.

"Kaogong Ji" says that the nine classics and nine dimensions are mentioned; "Zuo Zhuan" also says that the essence of heaven and earth is also mentioned.

It originally refers to the warp and weft lines of linen fabrics, which are derived from the north and south roads. After the cosmic view of Si Shang appears, it uses the meaning of the north and south and the longitude and latitude lines.

The gentleman was extremely proud of participating in the drawing of Jiuzhou map this time, but after thinking about it, he felt that it was too troublesome to explain it to his younger brother, so he had to say, "You don't understand it even if you say it. In short, Tai Sui Star can be the best water leakage timer in the world. There are twelve hours a day, and the longitudes and time are different, so it can be calculated."

"If you look at the height of the stars and moons, you will know when it is at night. If you look at the position of the moon on the Taisui Star, you will know when it is at night. After a little calculation, you will know how longitude the place is here."

Speaking of this, she thought of something, looked at her younger brother with a blindfold, and sighed, "What a pity. The earth under her feet is round, it seems that she has no choice but to circle the earth. The longitude is measurable, and the distance to the north is smaller. The earth is definitely not flat, but a ball."

None of the people present believed that the earth was flat. Shu Guitian thought about it for a while and asked, "Sister, can you use your method of measuring longitude on the boat?"

The gentleman shook his head immediately.

"It's not used. Even if there is a telescope, the moon on Tai Sui Star is too small and can't be seen if it's a little bumpy. And it's always troublesome. But if you dock on land, you can calculate it."

The family then reacted and asked repeatedly: "You still want to go out to sea?"

Shu Guitian nodded for granted and said, "Of course, after the world returns to unite, I may have to go to sea often. After the war is over, I have to live."

The mother muttered, "You can't spend your money now."

This kind of money is earned by life. Only one-third of the people who went out to sea together came back, and this was enough to make all kinds of preparations for food logistics.

Of course, they also make a lot of profits. Not to mention the 20th of the commerce shares of the Chamber of Commerce that Shu Guitian mentioned in the future, even if one-fifth of the gold is equal to them this time, it is also a huge wealth.

Shu Guitian heard this and said, "Who cares about how much money is? The world is so big that one must always be recorded in history books in the future. I, Shu Guitian, also participated in the feat of the first voyage to India. People who sail in the future must remember it."

"But... this time I am an intern. People remember most of our captain and representatives of the Ink Master, but they can't remember me."

"I want to do something exciting, and people must remember it. As for the money... I really don't care, because I don't lack it."

He glanced at his second brother who had been at home and said, "Second brother, why don't you go and register and I'll find you something to go to the South China Sea? As long as you are willing to live a life, you will get rich. There are many classmates there."

The prisoner Yue shook his head and said, "Forget it, I'm fine at home. Besides, I'm going, what should you do if your sister-in-law and nephew? I don't want to go. Some people go to the village community, some people get rich and some people die of illness."

Shu Guitian curled his lips and said, "I have said a long time ago that when the giant named us, we should have changed."

He looked at the prisoner Mi again and said, "Brother, before I left, I heard that the giant was interested in finding the place where sulfur, gold, silver, and copper that his two masters said was produced. And it was not far from us, did you find it?"

The prisoner Mi nodded and said, "I found it. I was not far from Juli, and I crossed the sea. But there... it is not like the rich place you went to this time."

"The people there are still using stones, and they can't even be slashed and fire. They went with the beads of Lin and exchanged them for a pile of pottery basins. Who would like to go?"

"I left a company of people there, and built a small town by the beach. I recruited some escaped people from all over the country, but there were not many people, three or five hundred people, and went there."

"The merchants are unwilling to go, so they can only look for gold, copper, and sulfur. But even if they find it, this mining is a problem."

"The fleet has walked a long way around the coast, and it is said to be very large. Some tribes do have some gold in their hands, and they are all picked up from the water. They don't know how to make gold. I heard that they will send people to find mines for a while."

"In fact, as long as you find gold, silver ore, copper ore, even if it is a sulfur ore, as long as someone mines it, there will definitely be many. But there is no one."

"What are you asking about this?"

Shu Guitian Yi clapped his hands and said, "What are you doing? This is an opportunity to leave a name for historical books! Brother!"

"Think about it, there were eight hundred people in Panyu City back then, and eight hundred people took down Panyu City. No matter how bad Panyu City is, there are still bronze ware. What do you think is there on that island? The tribes are still using stones, and they still looked like before Yanhuang in ancient times."

"As long as there are means, three hundred people are enough to roam such a large island."

"There must be a battle between tribes. Emperor Yan and Huang have fought a war. If I bring people to the island, there is no need to be too many. Three hundred people are enough to do something big."

"No one mines? It's simple. What did it do when Sishang was first established? Various villages and communities took turns to send people to mining and dig canals. Could it be that Sishang can be used, and that it can't be used there?"

"There are hundreds of thousands of people in such a huge island, and there are still mines that cannot be mined? Now sulfur, gold, silver, and copper are all urgently needed."

"Think about it, there are not many people, three or five hundred people, plus some craftsmen who can mine and prospect, which is enough. Since the giant said that his two gentlemen knew there was there, there was naturally there. Such a great merit..."

Speaking of this, the prisoner Mi Chou staggered and patted his younger brother on the shoulder and said, "Can you think of it, can you not think of it above? It's not that simple."

"I had a friend who was on camp before participating in the first expedition. There were many things in it, but it was not as simple as you thought."

"I'll ask you, there's still no land in Jiuzhou. There's still land in Huaibei and Jiangnan. No one has yet to go. Who would risk his death to run to the island?"

"It's not for gold and silver? But for gold and silver, if you dig out gold and silver, you must have to take care of it from above. It's impossible to dig it by yourself, and even if you dig, you have to have food? This can't be done overnight."

"Indeed, those tribes are still using stones, but they are not states like Panyu, but primitive villages. The land belongs to the public and everything belongs to the public, and there is almost no self-owned system, and there is no organization at all. The people in Panyu do have slaves, but even slaves, after they are released, they know to obey orders, and know what they can do and cannot do. Do those primitive villages that belong to the public know what obey orders?"

"Mining... People don't want to dig, but they can't go to the mountains and eat raw meat and drink blood. They used to live like that. I have to find a way to dig and find a way to let them accept it. Look... The South China Sea doesn't want to ask for local "long-term workers" in the South China Sea. Why? Because they are familiar with the environment of the South China Sea, what can they run into the jungle?"

"The above are also considering how to control where, not to make trouble, spend less money, and use less people, and provide a large amount of gold, silver, copper and sulfur. The matter inside is too complicated, not as simple as you think. If there is a country like the states of the South China Sea, those who fight the nobles and divide the land and cultivate the land will have their own fields and people will be equal to the world, and people will submit to it, the matter will be simple."

"The village members there are originally equal, the land belongs to the world, and wealth is more even than the equal exchange imagined by farmers. How can we do it? Who can do it? Let those who want to seek personal gain and harm others, it is impossible for the superiors to agree that they are unwilling to go to that kind of place. After all, there are many places where Si Shang makes money. Will they go to exchange pottery basins? Let the Mo people who obey the world and believe in equality and love do it... The reason is unreasonable."
