The walls of the house are white, with yellow double-open wooden doors, a table is placed under the eaves, and there are several chairs beside the table.

Behind the house is a wide orange orchard. At this time, the oranges are covered with white flowers, which looks extremely beautiful against the narrow leaves.

The room is facing the room in the orange orchard. The window is open. Behind the window is a desk. In a corner of the desk, there are thick books placed. The seals of these books contain the names of the books: "Ocean Encyclopedia", "Waves and Currents", "A Collection of Marine Life", "A Collection of Tropical Climate Cyclone in the East China Sea", "Drawings", "Meteorological Observation"

These books cover oceans, organisms, currents, climate, drawings and weather. They include books that tend to be popular science and professional books.

Most of the books are already a bit old.

And the owner of these books is just a little girl of eight or nine years old.

At this time, she was sitting at the desk, drawing something on a large drawing with a pen and a ruler.

“It’s done.”

The little girl put her pen aside and looked at the sea chart on the paper, which were drawn on it with two islands and a large area of ​​ocean. In addition to the longitude and latitude marked, there are contour lines on the island, contour lines in the ocean area, as well as routes and base marks. The water depth of the island's port is all about.

"Nami, are you drawing a nautical chart again?"

Behind Nami was a girl with blue hair, staring at the chart on the table.

"Norqi Gao?"

The sudden sound shocked Nami. She looked at the other party and said with a smile: "Well, I just drew a navigation chart."

"It's so awesome."

Noqigao looked at the chart, "I can't even understand the navigation chart, let alone draw it."

"It's just a copy based on the chart on the drawing."

Nami looked at the chart and said with a smile: "After all, to draw a navigation chart for an area, it requires a lot of data. In addition to orientation, longitude and longitude, there are changes in currents and tides, which are used to draw routes and anchorages. The depth of the ocean, identify the seabed topography, and also identify the seabed sediments. In addition, the nature of the coast, the depth of the port and the characteristics of the port, navigation marks, such as what can be used to distinguish the characteristics of the island, the residence equipment, and the location of the lighthouse. These all require field measurements. So I just mastered the basic elements of drawing the seabed."

"It's really troublesome." Nokigao rubbed his hair and looked at Nami and asked, "On-site measurement? Then you need to go to sea?

Nami nodded and said with a smile: "Yes, drawing a new chart requires on-site measurement, otherwise, the errors and actual deviations are too large. For example, the island where we live, the chart errors are too large, and at least I found three places."

"Why?"

Nokigao held his chin and looked at Nami and asked, "So you plan to leave Kokoaxi Village in the future?"

"My dream is to travel all over the world and draw all the maps of the world." Nami said seriously.

"Travel all over the world?" Noqigao widened his eyes, "Are you going to a very dangerous place?"

"certainly."

Nami nodded heavily and said, "But the knowledge I have not mastered is enough. Next, I plan to learn water level observation and navigation. After learning water level observation, I can first draw a chart around our island."

"oh."

Nokigao was not very interested when he heard this, and then asked, "Nami, do you want to go out and play?"

"No, I still have to read books."

Nami picked up a book, spread it out in front of her, and read it carefully.

“It’s so boring.”

Noqi Gao stretched and climbed onto the small bed next to him.

...

In the bay south of the island, summer and autumn are looking for prey in the sea.

It has been nearly two and a half months since I arrived in this sea area, and it is also May.

After more than two months of growth, from 18 meters in summer and autumn to 22 meters, and its weight reached nearly 70 tons.

More than two months, the weight of four meters and twenty tons has slowed down a lot compared to the previous growth rate.

Xia Qiu made two guesses about this slowdown.

The first guess is that I have entered the next stage of growth and my growth rate slows down.

For example, it only takes eight months for a blue whale to grow from seven meters to fifteen meters at birth, while it takes two years from fifteen meters to more than twenty meters, at least two and a half years to three years old.

To achieve an adult body, the body length is more than 25 meters, it takes about eight to ten years old.

I may have passed the juvenile stage and entered the sub-adult stage, so my growth rate slowed down.

However, my own growth is not the same as that of the creatures in One Piece world, and there should be no restrictions on the growth cycle.

The second guess is the change in one's own strength.

He left Nar Village himself, ate a naval colonel, and ate fourteen pirates, with the number and strength several times that before.

The strengthening this time is very huge.

You should know that before leaving Nar Village, before you digest Colonel Lido, you can withstand the power of the thirty-meter-long sea fish with your eighteen meters of body.

After eating Colonel Lido and Pirates, their strength increased again and became stronger, far exceeding that of fish of the same size.

When your body is strong, the energy you consume will become larger and larger.

For example, a pound of muscles consumes 6 calories while a fatty meat can only consume 2 calories.

After becoming strong, I am consuming a lot of energy every moment.

The energy I was originally involved in far exceeds my own consumption. After making up for the consumption, a large amount of energy was provided for my own growth and evolution.

But now, the energy consumption is too high, and the evolutionary energy you get from the body of a sea fish is more effective in consumption.

The remaining evolutionary energy greatly slows down one's growth rate.

These two guesses, Xia Qiu tends to be the second one.

This is more beneficial to yourself.

What you want is not to just become bigger, that will only become a target.

Even the island-eating monster that could devour the island was defeated by Dongli and Bloki.

The huge sea kings without wind belt are just appetizers for Lieutenant General.

What you want is powerful power.

Xia Qiu thought about swimming in the distance while releasing ultrasound waves, using echo positioning to locate other marine organisms.

Sonar system.

After eating dolphins, I successfully evolved a sonar system, including sound generators, receivers, and analyzers.

But it was relatively weak at that time, and the sonar range and sensitivity were not as good as one's own perception.

Later, Xia Qiu encountered two dolphin groups. After eating them, the current sonar system can be used.

Within three hundred meters, you can tell the distance, size and shape of the fish.

At the same time, summer and autumn can also actively receive high-frequency cycle waves to discover different creatures in the water.

Although it is not as good as a dolphin, it is already a very precious ability.

there.

To the northwest, it is 200 to 230 meters away from you, and the body length is about seven meters.
