Originally, when sailing in the sea, the surrounding environment should be similar.

Mars had never seen any other seabirds flying, or fish coming out of the water.

So the surface of the sea has nothing but waves, but it is precisely because of this wave that it does not feel so boring.

Now that the sea is flat, Mars is bored.

It's boring to the extreme!

The work was almost done, and after picking up shells several times on the shoal, Mars found himself with nothing to do.

Mars was a little calm, and that was because Mars had a little anticipation in his heart.

He hoped that his island would not fall under the attack of the sea monsters.

Then, take out your secret weapon and fight against these sea monsters.

So, this guy felt like his heart was beating faster because he wanted to test his preparation.

Mars didn't know what he was doing, so he either lay down for a while, or he just walked around the moving island, and when he couldn't do it, he jumped into the water, swam a few hundred meters, and then swam again.

When Mars was bored and expectant, Lawrence did his duty as a professional seaman.

He had been standing on the highest place, looking around.

"My father's eyesight is really good, but I should make him a tool. ”

Lawrence has good eyesight, and Mars has good eyesight, so usually, he doesn't think about telescopes at all.

But now, when the height of the person is raised, then a tool such as a telescope is needed so that you can see farther.

"Is the telescope two convex or concave mirrors?"

Mars's hand casually dug into the reef, and a hollow stone object resembling a telescope appeared.

Then, when Mars was making the lens, he couldn't think of what kind of mirror it was.

But I can't imagine that I can make it myself for testing.

When the two convex mirrors were mounted at the ends of the monocular, Mars picked them up and looked at them.

Now Mars is not focusing at all, so he must not be able to see it.

However, this monocular telescope is not going to be a rigid thing.

Mars was able to control the elongation and contraction of the reef, making it easy to achieve autofocus.

Then after focusing on the object, Mars will fix it.

"The effect is not so good, maybe the focus of the convex mirror is too short. Mars didn't know what words were used to describe it, but he said it as he understood it.

So for the monocular telescope I made, I still feel not so satisfied.

"Then let's make bigger and longer ones!"

The one in his hand was only a short and light one, but its long-range effect was not ideal, and it was not as good as Mars's own eyes.

So at this time, Mars's idea was to make bigger and longer telescopes.

With Mars in mind, a larger and longer telescope was made, and Mars focused again.

"It's good now, I can see the waves of the water from so far away, it's no longer glistening in the sun. ”

Mars looked at his giant cannon, which was more than two meters long, and then said.

"Bring it up. ”

Looking up at the high platform, Lawrence was still observing, so Mars climbed up with the telescope on his back.

Lawrence watched as Mars came up with a strange thing, and didn't ask.

Because he was analyzing the traces in the wind, judging the direction from which the wind came and what was there.

Mars had the huge telescope in place in a few clicks, and it could be rotated left and right for convenience.

In this way, it can be operated with one hand.

Mars, who was standing on the high platform, fixed the telescope on the outside of the high platform, and if he placed it on the high platform, he would not be able to stand with anyone.

So with such a placement, Mars and Lawrence can stand on a high platform and be able to use the telescope.

Mars was debugging the telescope at this time, and he needed this thing to work, so he had to tune it again.

The waves on the surface of the sea were small, and Mars looked in the easternmost direction, where there was nothing, still seawater.

Then he slowly looked northwest, only slightly off, and Mars saw that there was something more in the water.

When looking in the same direction from the eyepiece of the telescope, Mars could see nothing.

So Mars continued to look through the binoculars.

After seeing something again, Mars could already tell that his telescope was useful.

"Father, in that direction, I found a lot of sea reefs. They are all out of the water, some are very tall and large, some are small. ”

The direction of Mars's finger is the direction of seeing.

In this way, the voice of Mars was also heard by Lawrence.

Lawrence looked in that direction and saw nothing.

"Mars, where? Why can't I see it?"

"Father, with this, I saw with this. ”

Mars showed his father the telescope he had made, and then introduced it a little.

Lawrence looked at the cylinder and stepped forward.

Lawrence only glanced at it, then reached in front of Mars at this point and opened it.

There was nothing in his hand, but when Mars brought his head closer, he could see that there were some black and yellow crumbs in the palm of Mars' hand.

These were the things that Lawrence had harvested for so long on the high platform, and were about the same color as the sea reefs that Mars had seen with his telescope.

"Father, did you find out a long time ago?"

"These things are not the same as the sea reefs on our island, so I can't be sure yet, but now, after seeing far away with this, I know what these things I have collected are. ”

Not very far northwest of the moving island, a large group of sea reefs will appear in the sea.

Lawrence had already discovered it in advance, but he couldn't tell what it was, whether it was an island or a reef, because he hadn't seen it before.

However, now it is seen.

Then it can be judged that there is a huge group of sea reefs, and the composition of the sea reef is different from that of the moving island.

"Mars, this thing is really good, so far away, we can't see it in a place where we can't see. ”

"Father, I just stretched the distance between the two magic resistance stones, and then I was able to see far away, so I made this one, I didn't expect it to be very easy to use. ”

"Well, it's very useful, just leave it here, it will be useful in the future. ”

"Good!"
