Originally, there were no reefs on the northeastern periphery of the island.

However, there are many reefs in the three directions to the west of the island.

So if you get closer to the island in other directions, you'll need Mars to replace only the reefs that stand in your way.

However, none of these reefs are more than the distance of the reef group of the mobile island, so changing the location of the mobile island will make it easier to fill in the waters to the east of the moving island.

In the afternoon, Mars completely replaced the island.

It was originally a large island, but it became the cornerstone of the mobile island.

The surface part of the island is completely gone, and the underwater part is much less.

Mars followed his own plan to fill the rest of the island to the east of the moving island.

In a location close to the center island.

A platform two meters above the water, ten meters in length and eight meters in width was manufactured.

The rest of the water is filled with just a few reefs.

So it's not all out of the water at this time.

This platform is about a meter lower than the central island of the moving island.

But that's enough.

By the time he was done, it was already completely dark, and Mars had to stop and wait for tomorrow to start the work.

At this time, there was not much left of the nearby reef group that had been replaced by Mars.

Tomorrow I guess I will continue to set sail.

In the evening, Mars was planning, thinking carefully about how to build this device that could distill seawater tomorrow.

This thing must be a big one.

In this way, there will be a constant supply of fresh water.

This will allow the ability of the spring to form a stream on the moving island without any problems.

Mars has a lot of ideas, so this distilled water device is even bigger.

Thinking about it, Mars slowly fell asleep.

The stability of the moving island makes you sleep in it without feeling any swaying, so the more you sleep, the more fragrant it becomes.

After dawn, Mars gets up and the day begins.

Today's plan is to create a device for distilling seawater on the platform made yesterday.

So Mars replaced today's sea reef first.

He planned to first shape it with sea reef stones, and then transform them into near-transparent convex mirror magic stones.

In this way, the light can pass through the heat accumulation of this convex mirror, allowing the seawater inside to evaporate quickly.

The evaporated seawater will encounter a backflow pipe in mid-air, and then slowly slide down the surrounding pipes.

Then the water that finally condenses is fresh water.

Of course, this is one of Mars's principles.

As for the time of construction, more preparation is needed.

"It's made into a huge bottle, almost all of which are transparent. ”

Mars looked at the direct angle of the sun's rays and thought it would be better if the huge distillation unit had been built into a semicircular curved surface.

No matter where the sunlight comes from, it will be focused on the side of the sea.

Then on top of this curved surface is a small outlet like the mouth of a bottle.

This is where the water vapor can come out.

"The water vapor that comes out has to flow back from all sides, and there are not so many condensing equipment here, so we just rely on their gravity. ”

Mars watched as a huge bottle-like transparent thing was made, and then thought about making it at the mouth of the bottle.

Condensing equipment is something Mars doesn't have as many reefs to build at the moment. So now you can only make a giant ball at the exit.

There are two channels in this sphere, one is the 'bottle mouth' where the water vapor is heated upward, and the other is the bottom outlet.

This is where more and more droplets of water come together and then flow into the water.

Then it only needs to be at the bottom to allow fresh water to flow out.

The fresh water outlet pipe leads all the way into the pool in the reef.

A vent is added in the middle to create a flow of air pressure so that the pressure of the distilled seawater device is not too high.

The outside of the refill will be much higher than the water level inside the device, and the inside will be below the water level inside the device.

In this way, there will not be a large amount of water vapor coming out when adding water.

The whole unit is transparent and will look very clean.

Because you can see all the changes in it.

Lawrence watched Mars do something.

Then I watched Mars make a shape, tear it down and rebuild it, and then think about it again, and change it again, and in any case came and went several times.

When Mars was making this thing, he told Lawrence that he was going to build a device that could get fresh water.

The rationale was also explained to Lawrence.

So Lawrence said on the sidelines: "Mars, this thing is just an idea of yours now, and you need to verify it." This way, you will know what is right and what is not. ”

"Okay, Father, I'll go and verify. ”

By now, Mars felt that it should be about the same, so he planned to do what his father wanted.

The water level is two meters lower than where Mars is standing.

So at this time, you need to get the sea water from the low water mark to the high water line, and Mars can't keep fetching water.

Otherwise, after a whole day, I will have no time to rest at all.

Therefore, Mars needed to make a device that could automatically add water, so that the sea water could continue to flow.

This is actually very simple, Mars directly made a cylinder, one end is inserted in the seawater, and the other end is connected to the position of the water inlet of this distillation device.

Once this was done, Mars began to control the sea reef.

At this moment, in the seawater, one end of the cylinder rapidly expanded, and then a lot of seawater was wrapped in the sea reef.

At this time, Mars began to control them to shrink.

The seawater is squeezed up the pipe from low to high.

into this distillation unit.

Neither Lawrence nor Mars said anything as they watched the water come in, until Mars increased the water to the desired depth, and then stopped for a moment.

Leave the rest to the sun to scorch slowly.

After doing this, Mars will replace the other reefs in the seawater, and after replacing all the reefs here, he will leave.

By noon, more than half of the 100 litres of seawater that Mars had poured into had disappeared.

And there is fresh water flowing in the condensate pipe above the distillation unit.

The water Mars intercepted a little bit at the location of the pipe, and then tasted it with Lawrence.

This water has nothing but temperature, which is very different from the fresh water that Mars knows to exchange.
