Eagles have good vision because their visual cells have more objects called "macular" in object imaging.

The eagle's macula gathers 5 times more cells than humans, so it can see 4 to 8 times more farther away than humans.

So, you may want to ask, how far can a person's eyes look at the best time?

The scientists' statistics show that when the weather is clear, a person can see the farthest distance S (unit: km) on sea level, which can be estimated by the square of formula S = 16.88h. The answer is 25 kilometers!

Of course, it means seeing clearly in a vague way. If you can still see the target at 25 kilometers, like a magnifying glass, then you must be the god in the sky, the cousin of the general with a thousand-mile eyes!

When a person climbs onto a watchtower, how far can he see when his eyes are 35m from the sea level? Answer: 590.80KM!

Of course, observing sea level some tricks are considered as if they are normal people in the city.

When a person's vision is in the city, when it is greater than 500 meters, there is a blurred image of the scenery. When the distance is shortened to 250~270 meters, the outline of the scenery can be seen clearly. If you want to identify the types of flowers and trees, it must be shortened to within a few dozen meters.

However, if you have myopia, I didn't say it above.

Everyone's eyesight varies greatly. Some pilots can see planes 20 kilometers away, while others cannot see them as close to 8 kilometers.

In addition, humans have another characteristic of naked eyes. If they have seen planes and ships, they keep staring at them and let them gradually move farther away, they can only be seen after more than 10 kilometers. On the contrary, looking for planes out of thin air in the sky or ships on the sea, sometimes they can’t find them at a distance of 5 kilometers.

A pair of normal human eyes can reach infinite distance. At night, you can see the moon 380,000 kilometers away from the earth, or even stars that are hundreds of millions of light years. This is a proof.

The difference between humans and other animals, as well as eagle eyes is that.

Seeing and seeing clearly are completely different. You can also see people in the distance with myopia, but can he see clearly that he is his friend or who is scanning the streets?

At this moment!

Also under the night vision telescope, Zhu Zilong's younger brothers could only roughly find two large ships far away from NNNN.

But Zhu Zilong could see clearly outside the ship, and also see clearly how many people there were, even how many men and women there were on the ship. This is the difference between heaven and earth. (The Half Dragon Man Hawkeye is indeed a huge advantage in using it to peek at a girl taking a bath.)

Just when the younger brothers were still confused, Zhu Zilong had already seen clearly with the help of the half-dragon human and heavenly eyes of the night vision.

Immediately, his brows locked up.

The competition ahead is not the Chinese ship or the Japanese, but the Westerners.

That's right, the two big ships far away from NNN in front should look like merchant ships such as Portuguese.

Zhu Zilong also had little favorable feelings for the Portuguese and the like. In the original history, the Portuguese obtained the right of residence on the southern coast of the Ming Dynasty in 1557. They then regarded Macau as the pearl of East Asian trade. On December 1, 1887, the Portuguese directly occupied Macau, and Macau began to be forcibly rented by Portugal!

At this time, these foreigners in 1626 should have set up a business in Macau so that they would not directly export to overseas through Guangzhou.

Why did two of their big ships suddenly appear not far from Japan?

Zhu Zilong, who couldn't figure it out, decided not to think too much. It could be seen that the one behind was a pirate ship, attacking the merchant ship in front. They were all foreigners, which means that they were biting dogs!

It is natural to sit in the mountains and watch the tiger fight, but should we go over and eat something bad afterwards?

After thinking for less than ten seconds, Zhu Zilong felt aggrieved. It was too normal for a few large ships to sink on the sea, let alone hundreds of years ago.

If you die, you will die. No one will avenge them, and no one will know.

I finally caught up with foreigners who could be used as test subjects for naval warfare, and they are almost no threatening to fight in the internal battle. If you don’t take action at this time, when will you wait?

"It was a Portuguese pirate. Everyone was preparing to fight. The first column followed Zheng He's treasure ship, the second column cut off the rear route from the side, and the third column stayed behind."

After Zhu Zilong's order was issued, all members immediately took action.

Then, Zhu Zilong reached the bow of the ship again, got on the foremast, and issued orders from the watchdog from time to time, adjusting the direction, so that the distance between the two sides quickly approached.

On the Zheng He treasure ship of the copycat, the five-star golden dragon flag symbolizing the New Ming Dynasty fluttered in the wind. Well, however, this was useless, and no one could see clearly at night.

There was no national flag in the Ming Dynasty, and the five-star golden dragon was purely Zhu Zilong's personal hobby.

Needless to say, the five stars represent him as Zhu Zilong is a time traveler in the New China, while the Golden Dragon represents the Ming Dynasty and the Chinese as the descendants of the dragon. It’s just that outsiders don’t know it!

In Zhu Zilong's heart, safeguarding oneself and the country's interests is supreme.

Soon, the tricolor flag on the main mast in front proved that they were Dutch warships. Not far away!

It was not until this time that the foreign devils in civil strife discovered that a third foreign enemy suddenly came over under the night. Before, because Zhu Zilong's fleet was parked on the edge of the island, the night only made people think it was an island, so they could not find other ships here.

Zhu Zilong waved his hand and ordered: "The first level of battle is ready to begin!"

"Preparation for combat level 2!" "Preparation for combat level 3!"

"The human cannon was released (of course it is impossible, I'm just spoofing it)!"

Soon, in the battle group of Zhu Zilong's fleet, everyone put away all the tables, chairs, benches, pots, pans, and all kinds of debris to prevent damage during the battle or injury to their own people.

In the first and second floor gun deck, the armored captain and the gunmen loosened the cannon cables, and the gun door was lifted, and the gun door was extended to the outside of the cannon door.

There are not many artillery on the Fu Ship with 400-500 materials, two layers of gun decks, ten on both sides, and five on both sides. Each layer of gun decks has one squad leader and commander, each gun has one armor leader, two or three gunners, and two reserve personnel!

Wang Binghe came over and reported to Zhu Zilonghui: "Brother, these Maoist warships seem to want to run away."

Want to run, is it possible?

Zhu Zilong smiled suddenly and said, "You see that those boats have very deep drafts, so they must have robbed a lot of good things nearby, or there are a lot of goods on them. The hull is too heavy and the speed is reduced. Although it is in the upper wind direction, it cannot increase much speed for a while!"

Wang Binghe touched his head and said, "But brother, we are in the downwind, and the speed is slower than them, and we will not be able to keep up for a while."

"The other party is already a paper tiger. Let the people behind follow up at the current speed, open the lock of the treasure ship's diesel engine room, and preheat it. I personally go out and drive it. Be prepared for the battle. We will go up one-on-two to fight him first!"
