This chapter is "My Horse Feeds the Sheep" and adds ten thousand rewards.

With the precise positioning of the sextant, the Aketi pen was easily wielded and a rudimentary topographical map of the Flaming Islands was drawn in a notebook.

The Flaming Islands are not the kind of islands that are very scattered, and do not span a large area of water. It looks like the kind of fragmented oracle bone that is preserved in a museum, a complete tortoise shell broken into many pieces and then pieced together – of course, Liszt prefers to call it a broken shell.

The forced price of the turtle shell is too low, and the grade of the shell immediately goes up.

This shell resembles an oval leaf, with two pointed ends and a round middle, and the whole is in a northeast-southwest trend. There are three large islands in the northeast corner, each of which is close to the size of Ironhoof Island, according to Acker's depiction, and in the middle is the huge Flame Island, and Vortex Mountain is in the eastern center of the Flame Island.

In the southwest corner, four large islands make up the edge of the shell and, together with the Island of Fire, enclose an inland sea.

Of course, this is only a rough map, and many areas are inferences from Ake, which have not been carefully located, and the area of the islands and the area of the sea have not been calculated. It will take a long time to complete the smoke quest to map the map, and it will be a long time before you can find the lost invisible dragon.

In a word.

The archipelago is called the Flaming Islands, and the surrounding waters cannot continue to be called the Blue Sea, so Liszt simply gave it the name of the Sea of Shells.

All the coastal seas ruled by the Flame Nation in the future are called the Sea of Shells.

"Brother, Vortex Mountain is deep in the interior of Flame Island, whether it is north, south, or east, it is more than five hundred kilometers away. "Acker is very good at mathematics, and is proficient in the four operations of addition, subtraction, multiplication and division taught by Liszt, as well as elementary school knowledge such as opening squares.

However, Liszt has long forgotten all the mathematical knowledge above, and the unary quadratic equations will not necessarily be solved, let alone functions such as cos, sin, and power.

However, he remembered a lot of formulas for finding the area - the rectangle is "length" times "width", the parallelogram should be "high" and then multiplied by the "base", the triangle is "high" multiplied by the "base" and then reduced by half, the trapezoidal area is "height" multiplied by "upper and lower side lengths" and then reduced by half, and the circle area is the square of π times "radius".

Furthermore.

There are also some abstract image areas that need to be cut and supplemented to make them approximate rectangles, triangles, etc., or draw grid lines, calculate the area of the grid occupied by the image, and add them up.

When he handed over these formulas to Ake, he immediately carried them forward and became an important tool for studying magic circles and studying astronomy and geography. Therefore, it is easy for Archer to calculate the distance from Mt. Uzumaki to the sea, and conclude that each route will not be less than five hundred kilometers.

"Five hundred kilometers is okay, let Leo fly at full speed, and he can fly to the beach in about three or four hours. Liszt pinched his fingers and said.

However, it is rare to come to the Flame Islands, and Liszt is not going to go back like this, he has to map the island area of the Flame Islands first.

Completing the Smoke mission is more important.

This is about the whereabouts of his old friend Invisible Dragon - he carries the Smoked Grass Feast with him at all times, just waiting for the Invisible Dragon to come to the feast, and eat the Lost Dragon Soul Fruit by the way.

......

Leo landed, chewing on the potions and auxiliaries that Liszt had stuffed into its mouth.

Liszt and Aker outlined his idea of building the Flame City: "The city must be built, the maelstrom magic teleportation array must be developed, and the problem now is that there is a great danger in entering and exiting the maelstrom, and many fragile materials cannot be kept intact. ”

"You can set up a water curtain magic circle at the mouth of the whirlpool cave to slow down the ships passing through the maelstrom. ”

"But even if the ship slows down, it will still fall under the mountain. ”

"I heard my brother tell me the story of a canal between two seas, and the sea surface is at different heights, and navigation can be achieved through different valves to release and fill water. The canal story she tells is actually the Panama Canal that Liszt casually told in his spare time.

However, Liszt was obviously mistaken, the Atlantic Ocean and the Pacific Ocean were the same.

It is only due to geological influences that it cannot be dug directly, so the Panama Canal will rely on the drop of the river, and use the method of first raising and then descending, so that ships can pass smoothly. China's Three Gorges Dam is also a sluice-type canal navigation mode, and the world's earliest sluice-type canal is an ancient Chinese spiritual canal.

Liszt, who didn't know what he was talking about, nodded and said: "That's right, that canal is to use sluices to release water and fill water to complete the ladder navigation." So you mean, to build this kind of canal on the Vortex Mountain? I'm afraid no, with a 3,000-meter height difference, it's impossible to dig a canal. ”

"But magic can, Ake can design a water column magic array that can rise and fall, starting from the entrance of the whirlpool cave, relying on the mountain to arrange it, about thirty water column magic arrays with a vertical drop of one hundred meters can complete navigation. ”

"Even then, the resources consumed would be astronomical. ”

"When Ake completes the control of the ice attribute, he will study the changes in the nature of the soil attribute, and then use the earth magic to completely transform the mountain and reduce the loss of resources!" said Ake ambitiously.

She had read the magic books that Kenri Truth had brought with her from the Kingdom of Steel Ridge, including magical masterpieces from the days of the Empire with a sporadic moonlight.

It is said that at that time, there was a "heavenly canal" that led from the capital of the Moon Empire to the western border, which was supported by a magic array. However, the Heavenly Canal has long been annihilated in the long river of history, and many magicians have tried to verify the remains of the existence of the Heavenly Canal, but they have not yet found it.

Therefore, Ake was very keen to design a small section of the inferior copycat "Heavenly Canal" for Vortex Mountain.

She is also a magician, ancient magicians can do it, why can't modern magicians do it. The magic books she had read about the Ancient Moon Empire were all whimsical and eclectic. made her very emotional, for magicians, only the unthinkable can not be done.

It's a pity that the heyday of magical civilization is long gone.

Liszt was not so optimistic, as the magic net shrank, it was difficult for the magic array to draw magic power from the magic net, and it needed to be arranged with various precious magic materials.

The resources consumed in this way are absolutely astronomical, and now he feels struggling to raise two dragons, and he can't wait to grab a few pioneering orders a year.

Spending resources to build canals is not very realistic.

However, he didn't have the interest to sweep Ake: "Then wait for you to complete the earth-attribute elemental incarnation switch as soon as possible, and then further develop the Great Vortex Magic Portal...... Now think about how to use the resources of the maelstrom to transport resources and develop this huge archipelago as soon as possible. ”

Ark is not a person who is ambitious: "Brother, can you build many ships like the Flame, carefully strengthen them, accumulate resources and population, and then send them into the maelstrom. Ark crossed first, used magic to catch the big ship at the mouth of the whirlpool cave, and then put it aside to unload?"

"You mean to use the Flame as a one-time transporter?"

"Hmm. ”

"It's still a bit of a luxury, but it's really easy to do compared to transporting resources across the sea, but it's going to bother you and me a lot. ”

"Hehe, it's good that my brother doesn't feel tired, but Ake is looking forward to crossing the maelstrom again and studying the magic teleportation array. Maybe it won't be long before Ah Ke will be able to lay a new magic array by himself, and set up a teleportation array from Dark Horse Island to teleport to Flame Island!"

Liszt smiled, what "heavenly canal" and the like are unreliable, this is the best plan: "I'll wait and see." ”
