After becoming an octopus

For a solid house, a solid foundation is essential.

Zhang Zexi found a few large shells as digging tools, and started digging on the seabed at the selected location.

The soil on the surface of the seabed is mostly sand, so it is not difficult to dig in the water, but it takes more effort to dig deeper.

The black dolphin beast watched from the sidelines, not knowing why he was digging the hole for a while.

Zhang Zexi felt a little upset when he saw the black dolphin beast sitting on the side, and gave full play to his nature of squeezing labor, and passed a shell to the other party, "Quick, you come to help too. After digging the hole, I will go to the next door to pick it for you." Algae."

Of course, the black dolphin beast is not happy to work for no reason, but under the temptation of seaweed, it finally succumbed!

The little octopus was too small to help, it could only swim around nearby, releasing electric discharges from time to time, even Zhang Zexi, who was not close, felt the numbness from the electric shock.

Why the little octopuses can discharge is still one of the things that Zhang Zexi doesn't understand the most. Could it be that he can discharge himself, but he hasn't found a way?

Zhang Zexi was busy digging a hole while thinking about finding the reason in himself, but unfortunately there was no response. Thinking about it carefully, if he could discharge electricity, why would he feel paralyzed by the electric shock?

After thinking about it, a big hole has been dug with the black pig beast.

He dug this hole according to the shape of the bottom of the travertine, so that he could fill the hole with other things later.

Originally, he just wanted to dig a hole and bury part of the travertine, but since he dug out some shells, conchs and creatures that grow underground, he decided to add a layer of isolation at the bottom.

"When are you going to pick seaweed?" The black dolphin beast panted and threw away the shells, and finally dug the hole.

"Don't worry, let's pick up some more rocks, and when I'm done, I'll pick seaweed for you, even two more." Zhang Zexi said perfunctorily.

The black dolphin beast thought it would be easy to pick up stones, so it went to the nearby coral group.

There are many types and quantities of small stones on the seabed, and Zhang Zexi and the black pig beast quickly collected enough small stones.

Before coming back to the pit, prepare to bury the hole stone in the soil.

Before that, he spread a layer of small stones on the ground of the cave, and filled the gaps between the stones with soil.

The next thing to do is to find a way to stuff the hole stone into this pothole.This process is much easier than Zhang Zexi imagined. Originally, he thought that since the fluffy sponge can float under pressure, it would be difficult to control it up and down, but when he tried it himself, he realized that he was wrong. .

There is a buffer period for the floating of the weight on the fluffy sponge. When the fluffy sponge determines the weight, it will float slowly within a few seconds.After that, if you continue to add weight, the fluffy sponge will be suppressed and lowered because of this buffer period, but it will return to normal and refloat after a few seconds.

Therefore, within this buffer period, he can pull the fluffy sponge up, down, left, and right. As long as the force exists, the fluffy sponge will always be pulled by the force.

Zhang Zexi gently pulled the velvet sponge, stuffed it sideways along with the travertine stone into the hole, asked the black porpoise to help him fix the burrow stone, and then went to untie the rope to separate the travertine stone from the velvet sponge. The hole stone fell steadily into the pit.

After fixing the position of the travertine, he began to fill the gap between the travertine and the pit with small stones, and filled the gaps between the small stones with sand. A barrier between the travertine and the soil prevents borrowers from entering their houses from beneath the soil.

After the bottom filling is completed, the travertine is completely fixed.

The travertine is buried at a depth of about one meter, which can completely fix the travertine and does not hinder the use of space in the travertine. That is, when filling with sand, some sand falls into the inner hole through the hole in the travertine. , some cleanup is required afterwards.

Half of the travertine is buried underground, which is equivalent to having half of the 'basement'. The installation of the travertine has been roughly completed, but there are still many problems to be solved in this house, such as the holes that communicate with the outside world.

These holes connecting the outside are likely to give other creatures an opportunity. His idea is to plug the extra holes. After all, no one wants to live in a house with air leaks everywhere.

But the material used to plug the hole is still open to discussion, and he couldn't think of what to use for a while.

"Big octopus, we're going to pick seaweed." The black dolphin beast has been waiting impatiently, if it wasn't for the seaweed it wanted, it would have given up long ago.

Is Zhang Zexi the kind of octopus who doesn't keep his word?of course not!Anyway, he was tired after a while, so he simply went to the barnacle mountain next door to get some food.

The Black Pig Beast and Zhang Zexi came to the Barnacle Mountain together. As before, Zhang Zexi went in to dig barnacles and pick seaweed, and the Black Pig Beast waited outside the range of the Barnacle Mountain.

After everyone had eaten and drank enough, they headed back home.

After making an appointment with the black dolphin beast tomorrow to go to the place where the fluffy sponge grows together, Zhang Zexi kindly gave the reward of twenty seaweeds first.

On the second day, after Zhang Zexi settled the little octopus, he set off with the black dolphin beast.

Just as Zhang Zexi guessed, the place where the black porpoise lived was not too far from the barnacle mountain, but the distance was about the same as the distance from Zhang Zexi's lair to the barnacle mountain.

It would take Zhang Zexi three hours to walk this distance, but with a mount like the Black Dolphin Beast, it only took nearly an hour in total.

Zhang Zexi secretly wrote down the route. To get to the place where the fluffy sponge grows, he still needs to pass through the coral group where the clownfish live, and pass by the barnacle mountain.

This piece of coral is huge, and it took half an hour just to pass through it in a straight line. If Zhang Zexi had to walk by himself, he would have to climb quickly for an hour without being able to get out.

After leaving the coral group, there is a long canyon. Going down the canyon, it didn't take long to see the end, but the other side of the canyon is another scene.

The first thing that catches the eye is the sponge creatures of different shapes and colors. Most of these sponge creatures are in the shape of deer horns and water pipes, some are in the shape of rhino horn cups, and some are like big steamed buns.

Looking at it this way, it is quite appetizing.

"The fluffy sponge is inside." The black dolphin beast did not stop immediately after entering the sponge group, and continued to march inward for a certain distance.

Here and the edge are completely two worlds. The large sponges are covered in black, and this group of sponges seems to have lost their vitality and withered.

When Zhang Zexi saw such a scene, he immediately knew that it was a fluffy sponge.Excitedly, he jumped off the black dolphin beast, and slowly landed on a large piece of sponge.

His body was not supported by the velvet sponge, and through the black dolphin beast, he knew that the velvet sponge that had not been collected had basically no floating effect.

Lying on the sponge, the touch was different from what he had imagined. He climbed down from the sponge and peeled off the black fluffy sponge on the surface to reveal the white sponge substance underneath.

"Huh?" Zhang Zexi observed carefully, and he felt that this white substance was more like a sponge creature than the black cotton substance.

He felt it carefully, but felt a little weird.

The sponge will filter seawater through the pores of the body, and there is no movement during this process, but the sponge at this time has no sound.

They are dead.

Zhang Zexi was silent for a moment, these black flocs might not be sponges, but some kind of organisms parasitic in the sponges.To ask him why he judged that this is parasitic, it is mainly because the growth position of the fluffy sponge is the hole of the sponge organism.

Sponges rely on these pores to filter seawater to obtain the nutrients they need. After the pores are blocked, it is naturally impossible for the sponge to continue to survive.

However, he currently does not know whether this black floc is a parasitic organism or a parasitic corpse.Just like mushrooms, most of which grow from decaying wood, flocs may also parasitize after the sponge dies.

These are not the main purpose of Zhang Zexi, he came here just to collect more fluffy sponges, but it is not the main purpose of this time to get to the bottom of it.

After reacting, Zhang Zexi peeled off the fluffy sponge from the sponge body.After collecting the flocs on the sponge, the main body of the sponge creature was revealed. It looked like a large irregular white futon, with a diameter of about [-] meters and a certain thickness, but not very regular.

The octopus claw poked upwards, and the sponge creature immediately dented a piece, but as the octopus claw let go, the sunken part returned to its original shape.

The texture of this sponge creature is similar to that of artificial sponges, elastic and very soft, like a large white mat.After observing it again and confirming that it was really a large piece of dead sponge, he planned to remove the sponge as well.

Zhang Zexi didn't spend too much time among the sponges. Collecting sponges was really not a difficult task for him.He didn't take too many things at once, he cleaned up the fluffy sponge and the white sponge that was parasitized by the fluffy sponge. Anyway, he already knew the location, so he just came to pick it up next time he needed it.

After getting the things, Zhang Zexi originally wanted to go back to the lair first, but changed his mind temporarily. He planned to visit their new home and arrange everything that needed to be arranged. By the way, he picked more seaweed for the black dolphin beast, and got the fluffy Sponge, he'll probably stay in the den for a while until he can make something.

Before that, he might not go out, so it is necessary to prepare some seaweed so that the black dolphin beast will no longer work for him.
