"Outlying Island" Blue Moon Bay, in the wharf, Kong Da and Kong Er, two brothers, are leading the dragon and tiger teams, practicing day and night, even Bian Xi's jujube red horse is also fat and strong by the two brothers, changing the appearance of the wind and dust when they first arrived!

Lou ship, yes, it's the Lou boat with the dragon flag and black all over...... It was once again renovated by the brothers, and during the cultivation period in the mountains, they did not delay the task assigned by Lord Bian for a moment!

Before the preparation, Bian Xi personally feasted the two brothers, entered the courtyard of the outlying island, walked to the cabin, and drank all night, without getting drunk and returning! From then on, the two brothers vowed to follow Lord Bian Xi with all their hearts......

Because they knew what a great honor it would be to be able to enter the courtyard of the outlying islands, not to mention that they could walk to the small cabin halfway up the mountainside and drink three hundred cups with Lord Bian all night, which was beyond the reach of others, and they were already very satisfied!

As for the wind and rain pavilion on the top of the hill, it is a forbidden place of "outlying islands", and no one dares to have any extravagant hopes for it? Since the completion of the outlying island, Jiugong, Hong'er, Bian Xi, and only these three people can climb to the top of the Wind and Rain Pavilion at will!

According to legend in the island, there is a perennial lightning and thunder, wind and rain, it seems to be blessed by the gods, especially in the last 100 days, the purple gas on the top of the mountain is pervasive, and in the void, there seems to be a certain sound often, like a dragon roaring and a tiger roaring, like a phoenix roaring and a lion roaring......

This kind of sound, uploaded to the nine heavens, down to the netherworld, the aftermath of the world, around the beam for three days without stopping, shocking through the three realms, terrifying! So the people on the island were even more in awe of these three people...... Worship like a god!

On this day, the three of them went down the mountain, came to the dock, watched the practice of the dragon and tiger two teams again, and praised the achievements of the two brothers led by Kong Dakong, and by the way, they used the wisdom of later generations to add many new types of equipment to the ship, Sinan, compass, telescope, navigation chart, chronometer chronometer......

For example, the nautical compass, which has a circle on it, and the twenty-four characters engraved on it seem to be chaotic, but in fact there is a regular arrangement. They are all words that can be used to indicate directions.

The compass is composed of the twelve characters of the earthly branch (Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai) and the eight characters of the Heavenly Stem (A, B, C, D, G, XIN, REN, and 癸).

In addition, the "four dimensions" of the Bagua are also used to represent the four directions: Qian (northwest), Kun (southwest), Gen (northeast), and Xun (southeast). These 24 characters are arranged in a circle, which is equivalent to a circle of 360° now. After twenty-four equal divisions, each word indicates a 15° bearing.

These 24 characters are headed by "Zi", indicating due north, and then, in a clockwise direction, the earthly branches and the heavenly stems are arranged alternately. Mao is due east, noon is due south, and unitary is due west, but the armor of the heavenly stem is arranged from the east. In this way, the direction of the compass hand can be read.

As early as more than 2,000 years ago, skilled craftsmen polished and chiseled the magnet into a spoon shape, placed it on a smooth mirror-like chassis made of bronze, and then cast a directional carving. When the magnetic spoon stops rotating on the chassis, the direction of the spoon handle is due south, and the direction of the spoon mouth is due north.

Later, Hong'er and Jiugong Bian liked them, and made an ancient compass on the basis of Sinan. At this time, the compass was much like the compass used today, with a magnetic needle pointing in direction and a dial showing directions. Attaching a compass to a ship can guide navigation.

Telescope, in the process of sea navigation, observe the sea situation, identify nearby ships, find markers, etc., all use the telescope, it is an important instrument for navigation, also known as "telescope".

How it works...... It is the use of light refraction through the lens or light reflected by a concave mirror, so that it enters the small hole and converges for imaging, and then through a magnifying eyepiece to be seen, so that objects that cannot be seen or distinguished with the naked eye become clearly distinguishable. As for the magnifying glass, Hong'er said that it can be replaced by grinding crystal into a concave and convex mirror!

There are no books or documents that reflect the infinite curiosity of human beings more than nautical maps, because our eastern country has a long coastline and is also one of the first nations in the world to master navigation technology.

Jiugong said: "The maritime history of our ancestors can be traced back to 7,000 years ago." The Book of Changes recorded the story of Fuxi's "cutting wood for the boat and cutting the wood for the boat", and the wooden oars that appeared 7,000 years ago at the prehistoric civilization site of Hemudu are the ironclad evidence of the earliest navigation of the ancient people in China.

The original nautical chart is always between the image depiction and landscape painting, the Shanyu Island and Reef Map is not the name of a certain map, it represents the earliest form of recording the nautical chart in China, and is characterized by the fact that the main content of its depiction is the side graphics of the peaks, islands and reefs, so it is collectively called "Shanyu Island and Reef Map".

The course is free, and the sea is vast. Traveling on land, we understand that the route and the end point are there, while at sea, you are faced with more unknowns and adventures? Jiugong glanced at Bian Xi and said cautiously.

The chronometer is a specially designed instrument that can express the space-time movement of celestial bodies in a variety of forms on a whim. It is a combination of power machinery and many transmission machinery in a whole, the use of several sets of gear trains to slow down the movement of the wheel, so that it often maintains a constant speed, consistent with the movement of celestial bodies, astronomical clocks can not only represent celestial phenomena, but also time.

The above equipment ...... It's all Hong'er, when I accompanied Jiugong and Bian Xi, during the cultivation period, when I was idle, I borrowed the wisdom of the people of later generations, and after discussing with each other, I made it easily!

During this period, Jiugong and Bian Xi couldn't help but sigh secretly at Hong'er's ice and snow...... The two Kong brothers, as well as the people on the island who have never seen these novelties, are simply shocked after seeing them!

"Woooooooooo......oo With the sound of a trumpet! ”

When Jiugong, Hong'er, and Bian Xi followed the two Kong brothers and stepped on the black building boat again, they suddenly saw a fiery red flame, standing on the bow of the boat, and making a burst of neighing sounds, yes, it was the red horse that Bian Xi rode when he came!

At this moment, it was looking at its master with anticipation, Bian Xi hurriedly stepped forward, patted the old man's neck with his hand, and then gently touched its head to show his miss...... The jujube red horse seemed to feel the breath that had not been seen for a long time, and it instantly lowered its head and licked Bian Xi's hand even harder!

Suddenly, Bian Xi took a leap, pressed the horse's back with his hand, turned over directly on the horse, used both hands hard, and pulled the reins back, only to see the jujube red horse "chirping" After a neigh, the entire front half of the body instantly rose into the air, the hind limbs supported the ground, and the front hooves were volleyed...... A round of red sun on the vast sea, the sun rises, the morning sun is like a sunrise, the five stars shine, and the east is good!
