The island is getting closer and closer.

"It's much smaller than Treasure Island, but bigger than the beach island!"

Chen Changan climbed up the mast and barely saw the entire picture of the island.

It looks like... A rectangle and two isosceles triangles, Chen Changan didn't know how to describe this strange island for a moment, and suddenly a flash of inspiration in his mind:

“Isn’t this a large gamepad?”

"I'll just call you the handle island!"

As the flying Henan People sailed, Chen Chang'an was getting closer and closer to the island.

As an old-fashioned Kinxian, Chen Changan not only knows a little about delivery knowledge, but also learns a little about surveying and mapping from the old man in Diaoyuba, and quickly infers the length and width of the island.

Some rectangular islands are about 25 meters long and about 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 often gets sick, Chen Changan has time to learn more mathematical knowledge. He calculated the real area of ​​the handle island in a blink of an eye - more than 320 square meters.

After approaching the beach, Chen Changan jumped off the boat.

"Chirky~"

The orange, who felt most distressed by his master, screamed, as if reminding Chen Changan of the old news on Treasure Island.

Although the Stone of Choice said, "There is an unmanned island there, without any extraordinary creatures, suitable for farming and development!"

But he won't take risks in person. Although fish cannot get ashore, ghost fish can do it.

Chen Changan turned his head and looked at the five undead marine creatures under the sea, and said with a smile:

"Are there any fish that are willing to spy on my information? If you don't want to go, raise your hands over your head."

Killer whales, narwhals, great white sharks, basking sharks, and real bulls all raised their little hands (fish fins), but what made the fish feel desperate was that even if they tried their best to lift their fins, they could not be raised above their heads.

Chen Changan showed the smile of the capitalist in the lighthouse:

"We need to pay attention to democracy. Every fish and every vote. You can vote for other fish or yourself. The fish with the most votes are responsible for going ashore and detecting the dangers for me."

After a "shark battle" battle, the killer whale was voted for 4 votes, and even the narwhal pierced it without hesitation.

The killer whale was sad and swam shore silently and began patrolling the handle island.

Chen Changan looked at the killer whale's crying and tears, and even suspected that it would learn the "Sad Palm of Sadness" without a teacher.

The pattern of the handle island is not complicated. The two isosceles triangles are actually "mountain" about fifteen meters above the horizontal plane, and the rectangle is a slope slightly extending towards the top of the mountain.

Although the island is not big, about six times the area of ​​the flying Henan Ren, a large piece of slope is 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 risk factors. The strongest king on the island was just a delicious sea turtle.

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, cleaned up the impurities in his body, performed bloodletting therapy popular in the medieval European era, and then removed useless things like the turtle shell and gui head.

Sprinkle some salt, pour some soy sauce, and add a few dried chili.

Not long after, the meat smell filled the air!

Chen Changan felt sorry for the fall of the strongest king of Handle Island. He sincerely hoped that it could erase the great way, reverse life and death, rise in destruction, recover from nirvana, and live out a second life!!!

Tears unconsciously remained from the corners of their mouths.

"It smells so good!"

Chen Chang'an has three bowls of sea turtle soup, dried soup, dried soup soul, dried soup and dried soup!

After drinking and eating, Chen Changan finally started to do serious business.

Coordinate system!

Six choices have found six opportunities for Chen Changan. He is not a fool who carved a boat and asked for a sword.

Chen Changan collected the only geographical knowledge left in his mind, assuming that the direction of sunrise is east and the direction of sunset is west, and using the handle island as the origin, he began to calculate the location of each opportunity and a brief chart.

The ocean forest, 23 degrees southeast, sailing 13 kilometers... The mermaid elder looked warm in the ancient road, Chen Changan felt panic, and the back tightened, and viciously swore in his heart:

Only insects go to the ocean forest!!!

Kingsoft Island is located 95 kilometers south of the south;

For marine shipyards, we need to use the Pythagorean theorem and acute triangle function in a right triangle, and the final calculated position is...

Chen Changan felt that he had to become stronger than the unknown existence of the city of the sky and the asdfhadjoi under the sea.

After four opportunities on the sea surface to locate, Chen Changan successfully drew a simple map of the sea area near the island. Every time he traveled in the future, he could constantly record the sea landscape for locate and enrich the content of the chart.

No wonder ancient navigators often mastered a wealth of mathematical knowledge!

Live until you grow old and learn until you grow old!

Before going to bed, Chen Changan opened the forum and habitually shared the new knowledge he had mastered into the "Collection of Novice's Survival Experiences", but suddenly found that the deep-sea forum polluted by the original ** teaching, ambitious, celebrities, and politicians was swept by a content storm caused by Chinese math enthusiasts.

It has destroyed all the pickled stench, and dominated the hot searches of the entire deep-sea forum!

The number one hot search: Mathematics!

The second place in the hot search: trigonometric function!

The third place in hot search: geography!

The fourth place in the hot search: map drawing

No. 5 in the hot search: fellow villager

Everything starts with the task of sleepless nights.

There are hundreds of millions of Chinese people who have completed the sleepless task, and each of them has obtained the ability to draw time props at one time.

Among them, the Stone of Direction is the most common prop, with the number of distribution exceeding 100 million.

Direction Stone can mark six different locations for the captain and provide the ship's sailing distance to six locations.

Just like Chen Changan used a trigonometric function to draw a map of the sea area near the handle island, the progress of mathematics enthusiasts and geography experts far exceeded that of him, and fragmented small 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 actively shared the data of the Stone of Direction. Mathematics enthusiasts around the world have been online one after another, connecting the fragmented small charts into lines, and lines into pieces.

In the end, human society has accumulated thousands of years of mathematical background and suddenly exploded!

Millions of calculation posts quickly exchanged information and finally merged by dozens of "Da Vinci-style" big shots in the field.

At this moment, the panoramic view of the human seas was divided and worked together by countless mathematical enthusiasts, geography experts, engineers, modeling tycoons, and computer masters, and they worked hard to calculate its true appearance! It calculated a brand new world!

The top mathematical tycoons divided all the sea areas into 26 large sea areas with twenty-six letters, and each large sea area was divided into 1,000 to 10,000 small sea areas, and each sea area was named after the location with the highest vector of the direction stone.

The sea area where Chen Changan is now located is the No. X shipbuilding Sea!

At the beginning of the deep sea world, people were separated by hundreds of kilometers. Unless they were like Chen Changan, eight billion humans had almost never seen humans other than their relatives!

But from today,

Even between the sea and the sky, there is only one sea, one person, and one raft, silently enduring the torture of loneliness,

He could point in a certain direction, and said with anticipation:

"Zhongle! You can see fellow villagers by swimming there for 120 kilometers!"
Chapter completed!
