Chapter 101 Land
What a surprise, Liu Ze said with emotion.

He really didn't think about that, and suddenly went to a strange place, only immersed in the shock brought by this strange island, and then there was a camp roar, and he was caught in the panic of food shortage, and he didn't even think about it. this matter.

Although I have explored around this small island before, it was mainly to find new camps and food, not to mention that when I stood on the periphery of the small island and looked into the distance, I didn't see any land, so I took it for granted that this was a place far away from the mainland. islands.

And ignoring the fact that the surface of the earth can be approximately equal to a sphere, the distance viewed from a distance at the biological level on the surface has a positive relationship with the height of his field of vision.

It can be obtained through a simple mathematical calculation, assuming that R=the radius of the earth, H=the height of human vision, and L=the distance that people can see.

These relationships are equivalent to a right triangle, where R+H is the hypotenuse, and R and L are the sides respectively.

The calculation of side length can be incorporated into the calculation formula of right-angled side in junior high school, that is, (R+H)=R+L
The known radius of the earth is 6371 km, so we can get a conclusion:
The higher you stand, the farther you can see.

Under normal circumstances, on flat land, ordinary people can only see land within a range of 4 to 10 kilometers.

Standing at a height of 100 meters, you can see about 35.7 kilometers away. This gap is very large.

In the early morning of the second day, Liu Ze set off with Chao Zhongchen and others with excitement.

Before reaching the top of the mountain, when I climbed halfway up the mountain, I found a piece of dark land on the eastern horizon. As the height of the mountain increased, the appearance of the land in the distance became more obvious.

After climbing for another half an hour, everyone finally reached the top of the mountain.

On the top of the mountain there are some big round rocks standing on the south side. In the middle is a fairly flat open space, about the size of a room. Liu Ze and the others just stand on it and it is just packed. There are about ten pine trees growing on the north side, all facing The sky stands upright, very imposing.

There was a wind blowing on the top of the mountain, and from time to time, clouds drifted past Liu Ze, covering the land to the east of the island. Standing on the top of the mountain, Liu Ze felt as if he was dreaming.

Wang Shanbao beside him danced happily, pointing to the land in the distance and shouting excitedly: "Commander, look, it's land!"

Old Kong, who was flushed and gasping for breath, also looked in the direction of Wang Shanbao's finger. He was old and frail, and it was not easy to climb this mountain. Liu Ze didn't want him to come, but he couldn't be persuaded, so he had to let him Follow behind Wang Shanbao and ask Wang Shanbao to take care of him.

At this time, the cloud had drifted to the north, which just exposed the land. The view from the top of the mountain was good, and Liu Ze happened to be able to see it clearly.

Behind the entire coastline are endless plains and hills, and high mountains are only looming in the direction of the end of the field of vision, but the strange thing is that there are no traces of human buildings on the entire land that can be seen.

Liu Ze couldn't help but wonder, is this piece of land extremely remote?still. . .

Wang Shanbao, who was behind him, was also shocked by the distant scenery, suddenly moved his nose a few times, and asked pantingly, "What fragrance?"

Could this be the aroma of an unexplored continental world?

"It's the fragrance of flowers around you." Liu Ze was completely brought back to his senses by Wang Shanbao's question. Looking at his silly appearance, Liu Ze couldn't help laughing, and pointed to the nameless wild flowers under his feet. Shouted, "Wang Shanbao!"

"Here!" Wang Shanbao stood at attention when he heard the command, his expression was no longer joking, but was replaced by a soldier's seriousness.

"Record, let the pottery kiln burn ten pieces of pottery boards, and make them bigger! The letter: This place is called Xinju Prefecture, and it is [-] miles away from Daming in the east. It is the sacred and inviolable territory of Ming! On the first day of September in the first year of Chongzhen, Shaanxi Junxian People's Army stays."

Liu Ze thought for a while, and then added: "Leave two pieces on the top of the mountain, and the other eight pieces are buried in all directions around the island."

"As ordered!"

Wang Shanbao was very happy. In fact, he had already regarded this small island as their own in his heart. How could there be no one else on this island except them!Now that Liu Ze asked him to erect a pottery stele, it was exactly what he wanted, just like buying a house or land requires a deed of land. This pottery stele is naturally the best proof of ownership of the island.

And the monument was left in the name of the Ming Dynasty's legal principles because the civil war was a last resort, and the foreign war should be consistent with the outside world.

At this moment, Lao Kong, who had calmed down, smiled and said to Liu Ze while stroking his beard, "Xinjuzhou, what a name."

"Haha." Liu Ze also laughed along with Lao Kong. In fact, he was a little selfish. Suzhou was his hometown. Facing a completely unfamiliar environment, I miss my hometown even more. Now that I want to name this small island, Liu Ze just added the word "new" in front of Suzhou without thinking about it. In this way, it is "new" Suzhou".

After everyone laughed together for a while, Liu Ze's expression became serious again.

The old people who followed Liu Ze knew that this was Liu Ze's expression when he was thinking about a problem, so once Liu Ze behaved like this, everyone stood aside and didn't bother him lightly.

Liu Ze thought he had to go to the land on the east side. Although there seemed to be no people in the distance, if this is really the European area, then it is necessary to explore it. In this entire continent, you may still meet humans. Well, then we can roughly determine the current time.

On the way back, Liu Ze kept alternating between the ecstasy of discovering the land and the fear of the future. Finally, he made up his mind to explore. Of course, the premise is that he must be prepared.

After all, no one can say for sure what it looks like over there.

"Huh? What is this?" Liu Ze picked up a piece of off-white stone that looked like a layered cake from the passing stones, "Is this limestone?"

Chao Zhongchen, who was walking ahead to explore the road, heard Liu Ze's voice, hurriedly walked back a few steps, squatted in front of the pile of stones that Liu Ze had just picked up, and carefully identified them. After a while, Chao Zhongchen raised his head, very He said happily: "Big cabinet, that's right!"

Liu Ze finally confirmed that the limestone is widely distributed.

In the wild, limestone generally appears in shallow seas, because most limestone is formed by the sandy soil on the seabed after a long period of changes.

"It seems that we need to use this preparation time to explore the mineral resources on this small island. With limestone, we can make cement and burn lime."

"In the future for steelmaking, quicklime can also be used to filter out harmful substances such as sulfur and phosphorus. It seems that there is still work to be done."

For the sake of safety, Liu Ze's so-called adequate preparation is to wait until the thunderstorm weather, charge the slate again, and then set off, so as to be safe.

Taking advantage of this waiting time, another lime furnace was built. The simplest lime production process is to lay limestone and fuel (wood) in layers, and then ignite and calcinate for a week.

The natural rock whose main component is calcium carbonate can be decomposed to generate carbon dioxide and calcium oxide when calcined at high temperature.

All natural rocks with calcium carbonate as the main component, such as limestone, chalk, dolomitic limestone, etc., can be used to produce lime.

Shells can also be used as raw materials, which are fired into shell ash and used as quicklime.

It is also wonderful to pack lime powder (it can also be used in the defense of the city).

Thinking of this, Liu Ze subconsciously touched his beard, hey, it was short, it didn't grow when he was besieged by the Ming army.

Strange!Looking at the people around him, there were no changes, Liu Ze was full of question marks, he didn't shave me.
