The island is getting closer.
“Much smaller than Treasure Island, but bigger than Beach Island!”
Chen Changan climbed up the mast and could barely see the entire island.
What it looks like...a rectangle plus two isosceles triangles. Chen Changan didn't know how to describe this strangely shaped island for a while, and suddenly an idea flashed in his mind:
"Isn't this just a large game controller?"
"I'll call you Handle Island!"
As the flying Henanese sailed, Chen Changan got closer and closer to the island.
As a veteran key fairy, Chen Changan not only knew a little bit about midwifery, but also learned a little bit about surveying and mapping from the fishing guy, and quickly deduced the length and width of the island.
The rectangular part of the island is about 25 meters long and 10 meters wide;
Two isosceles triangles, with a base length of about 5 meters and a height of about 15 meters;
Thanks to the strong physical education teacher who was often ill, Chen Changan had time to learn more mathematics. In a blink of an eye, he calculated the true area of the handle island - more than 320 square meters.
After approaching the beach, Chen Changan jumped off the boat.
"Tweet~"
Chengzi, who felt most sorry for his master, screamed, seeming to remind Chen Changan of the past on Treasure Island.
Although the Stone of Choice said, "There is an uninhabited island there without any extraordinary creatures, which is suitable for farming and development!"
But he would not take personal risk. Although the fish could not come ashore, ghost fish could.
Chen Changan turned his head and looked at the five undead marine creatures under the sea, and said with a smile:
"Is there any fish willing to spy on me for information? If you don't want to go, raise your hands above your head."
Killer whales, narwhals, great white sharks, basking sharks, and bull sharks all raised their little hands (fins), but to the despair of the fish, their fins could not be raised even if they tried their best. Overhead.
Chen Changan showed the smile of a capitalist from a lighthouse country:
"We have to pay attention to democracy. One fish, one vote. You can vote for other fish, or you can vote for yourself. The fish with the most votes is responsible for coming ashore and detecting dangers for me."
After a "shark vs. whale fight", the killer whale was voted out 4 times, and even the narwhal stabbed it in the back without hesitation.
The killer whale was dejected, swam ashore silently, and began to patrol Handle Island.
Chen Chang'an looked at the orca's tearless appearance, and even suspected that it was trying to teach itself without a teacher.
The layout of the handle island is not complicated. The two isosceles triangle handles are actually "mountain tops" about fifteen meters above the water level, and the rectangle is a slope extending slightly toward the top of the hill.
Although the island is not big, about six times the area of the Flying Henanese, a large slope is full of soil suitable for farming.
As a Chinese, Chen Changan said: DNA has moved!
The killer whale turned the handle island three times and three times, but did not find any dangerous factors. The strongest king on the island was just a turtle with delicious meat.
As for why the first impression of killer whales is that their meat is delicious?
five minutes later.
Chen Changan respectfully asked the turtle to take a hot bath, clean the impurities in the body, and performed the bloodletting therapy popular in the European Middle Ages. Then he removed the turtle's shell, guillotine and other useless things.
Sprinkle some salt, pour some soy sauce, and add a few dried chili peppers.
Before long, the aroma of meat filled the air!
Chen Changan felt sorry for the fall of the strongest king of Handle Island, and sincerely wished that he could destroy the great road, reverse life and death, rise from ruin, recover from destruction, and live a second life! ! !
Tears fell from the corners of his mouth unconsciously.
“It smells so good!”
Chen Changan drank three bowls of turtle soup in a row, drying the soup for the person, drying the soup for the soul, drying the soup for the master!
After having enough wine and food, Chen Changan finally got down to business.
Coordinate System!
Six choices found six opportunities for Chen Changan. He was not a fool looking for a sword.
Chen Changan collected the remaining geographical knowledge in his mind, assumed that the direction of sunrise was in the east and the direction of sunset was in the west. Taking the handle island as the origin, he began to calculate the locations of various opportunities and a brief chart.
Ocean Forest, 23 degrees south by east, sailing 13 kilometers... The mermaid elder looked like he was on the old road. Chen Chang'an felt uneasy, tightened his grip, and swore a vicious oath in his heart:
Only bugs go to the ocean forest! ! !
Jinshan Island, located 95 kilometers due south;
Offshore shipyards need to use the Pythagorean theorem and acute trigonometric functions in right triangles. The final calculated position is...
Between the city in the sky and the unknown existence under the sea, Chen Changan felt that he had to become a little stronger.
After locating four opportunities on the sea, Chen Changan successfully drew a simple map of the sea area near Handle Island. Every time he travels in the future, he can continue to record the sea scenery for positioning and enrich the content of the chart.
No wonder ancient navigators often had rich mathematical knowledge!
Live until you are old and learn until you are old!
Before going to sleep, Chen Changan opened the forum, habitually sharing the new knowledge he had mastered in the "Novice Survival Experience Collection", but suddenly found that the deep-sea forum, which was originally polluted by cults, careerists, celebrities, and politicians, was actually polluted by cults, careerists, celebrities, and politicians. A content storm started by Chinese mathematics enthusiasts swept across.
It crushed all the stench and dominated the hot searches on the entire deep sea forum!
The No. 1 hot search: Mathematics!
The second most popular search: trigonometric functions!
The third most popular search: Geography!
Hot search No. 4: Map drawing
The fifth most popular search: Fellow
It all started with an all-night mission.
There are hundreds of millions of Chinese people who have completed the task of staying up all night, and each of them has gained the ability to extract time props at once.
Among them, the direction stone is the most common prop, with more than 100 million issued.
The Stone of Direction marks six different locations for the captain and provides the ship's sailing distance to each of the six locations.
Just like Chen Changan used trigonometric functions to draw a map of the sea area near Handle Island, mathematics enthusiasts and geography experts far surpassed him, and one after another fragmentary small sea charts were drawn.
Once the direction stone provides the same location, it means that the sea areas represented by the two charts are connected and can be merged into a larger chart.
More and more Chinese people have taken the initiative to share the data of the Directional Stone, and the surviving mathematics enthusiasts around the world have come online to connect the fragmented small sea charts into lines, and the lines into pieces.
In the end, the mathematical foundation accumulated by human society for thousands of years suddenly exploded!
Millions of computing posts quickly exchanged data and intelligence, which were eventually summarized and integrated by dozens of "Da Vinci-style" experts in all fields.
The panoramic view of the human sea was, at this moment, being deduced by countless math enthusiasts, geography experts, engineers, modeling geeks, and computer experts who worked together to calculate its true appearance! A new world has been calculated!
The top math masters divided the entire sea area into 26 large areas with 26 letters. Each large area was divided into small sea areas ranging from 1,000 to 10,000. Each sea area has a direction stone pointing to the highest vector. Place naming.
The sea area where Chen Changan is now is the No. X shipbuilding sea!
When they first arrived in the deep sea world, people were separated by hundreds of kilometers. Unless they were idiots like Chen Changan, the eight billion humans had hardly seen anyone other than their relatives!
But from today on,
Even if there is only one sea between the sea and the sky, one person and one raft, silently enduring the suffering of being alone,
He can also point in a certain direction and say expectantly:
"I'm sure! If I swim a hundred and twenty kilometers there, I can meet my fellow villagers!"
