At noon, Mars and Lawrence looked at the island opposite under the gazebo and went to take a nap.

It's noon, and it's impossible for people to do things.

So the only way to rest is to find a shady place.

It wasn't until the afternoon, when it wasn't very hot, that Mars and Lawrence set off.

They walked from the shallow position to the edge of the reef group in the southwest, and then here, Mars began to work.

He made a way out of sea reefs that could directly cross the water to the island.

Then a connected transfer slot was made next to it.

One end of the tank is in the water in the southwest corner, allowing the displaced sand to slide directly to the west of the moving island that needs to be filled.

This also saves Mars a lot of physical energy.

Lawrence had already understood Mars's plan, so after looking at this thing at this time, he also found it very convenient.

With the tools in place, Mars began to replace the sand and reefs.

Because this angle is sufficient, the reef and sand on this island can be replaced and rolled directly down to the mobile island.

In addition, Mars can control the sea reefs on his island, so he doesn't have to worry about them being able to congest.

In this way, as long as Mars is replaced quickly enough, a lot of reef and sand will enter the western area of the moving island.

Therefore, the work efficiency of Mars will be very fast at this time.

An island may be large, but it will start to grow smaller after being quickly collected.

It took Mars only a short time to make the island's bare reef disappear and close to the soil.

However, the current Mars is mainly to expand his mobile island, so he will not stop at all.

As a result, the soil and some of the vegetation were poured into the top of the moving island.

However, so many sea reefs and sand entered the moving island, only to find that it was as if nothing had entered.

There is no reef or sand out of the water.

However, it is necessary to stop at this time, because the sun has already set below the sea level, and it is impossible to stay here any longer.

Back at the stone house, Mars and Lawrence looked a little embarrassed.

Because they both spent an afternoon displacing the sea sand and then transporting it.

Although these sea sand and reefs flow into the mobile island automatically.

However, there will still be dust when it flows, so a lot of it falls on the bodies of the two people.

But none of these things matter, because if you jump into the sea and swim a few laps, there is nothing.

Mars and Lawrence went to dinner, and by the time they had eaten, the sky had gone completely dark, and the whole world had become pitch black.

In this way, the two of them didn't think much about it and went straight to rest.

One night, the waves of the sea were slightly silent, and Mars and Lawrence slept soundly.

But after midnight.

The sky in this side of the world seems to be drifting with snow.

There were a lot of things falling from the sky.

But they are not snow, but ash.

A large cloud of dust was carried by the breeze from the northeast, and when it arrived, it began to fall.

Because the sound is extremely low, so low that it is silent.

So someone as sensitive as Lawrence didn't hear it.

The dust falls in the seawater and is sunk to the bottom by the seawater. Falling on the reef of the island, some of them survived, and some of them slipped into the sea and continued to sink.

Mars and Lawrence, who woke up in the morning, pushed open the door and saw a big change in the moving island.

Because of the pavilion on the mobile island, the place where fresh water was collected has fallen into a lot of dust, which is very slight individually, but after a very large amount, it will accumulate into a pile.

Mars looked at the gray dust piled up there, and then felt a little helpless.

I used to collect fresh water, but now, it has become a dust collector, which has to increase my work.

"Father, last night?"

"These things are too light, lighter than the wind, I don't feel them, but these things should be fine, they just fell on us. ”

Lawrence's hand grabbed it directly, and then found that it looked like a pile but was very soft.

And then after there is no harm, so tell Mars.

Mars saw that his father had no problem holding it, so he put his hand on it as well.

Now that it has been formed, there is no problem in grasping it.

"It's so soft, it feels like you're touching extremely fine soil. ”

Mars sensed the delicacy and said.

"You have found and possessed the volcanic ash, and you can add to the replacement. ”

Mars was still feeling the unique delicacy, and then he saw the hint.

"Is this volcanic ash?"

Mars looked at the thing, and then felt that his previous guess must have been correct.

This volcanic ash can only be encountered in nearby places with volcanoes, because when the volcano erupts, the volcanic ash is formed, and it is the culprit of the harsh environment that covers the sky and the sun.

"Volcanic ash can be replaced, it can be replaced by sea reefs, and the replacement is volcanic ash or its industrial products. ”

In the past, when the reefs in the sea of this world were replaced, they could only be replaced with sea sand.

But now, Mars has discovered that this thing can actually be added to the replacement of sea reefs.

In other words, the use of sea reefs can replace volcanic ash and industrial products in which volcanic ash participates.

Mars doesn't know what this ash can do with yet, but just look at it, the finished industrial product, and you can see what it does.

So at this time Mars continued to look.

"The replacement of volcanic ash into its industrial finished products including cement, which can only be replaced at present, cement has high solidification and plays a very important role in industrial construction. The ratio of the weight of the reef to cement is five to one, and the ratio of volcanic ash to one is four to one. ”

After reading these presentations, Mars can already conclude that this is a new method of substitution.

Because the same item can be replaced with two items from this world.

The only possibility is that the proportions are different, but these things only give themselves an extra possibility of replacement, so Mars will not completely remember everything, and can check it when the time comes.
