Wait for the shallow carrier to slowly twist its body and swim to the deep sea.

What a … meaningful journey!
Chapter 20 Gas Reservoir and Epidemic System
The journey on land is meaningless. Although the land has almost nothing worth remembering, it has gained some knowledge.
Like qi.
Lin discovered long ago that the air in the water would float to the other side. Lin never cared about this matter until now, when Lin suddenly remembered why they would go instead of going. Can they resist gravity?
Not really, it’s just that gas is lighter than water, so they will be squeezed out by water, and the land where they are located is full of gas.
Now Lin has slowed down the speed of the aircraft carrier because of covering the carapace, and her swimming is not as flexible as before.
But … What happens when you add angry words?
Lin’s aircraft carrier system has built an oval-shaped balloon combination, and the airbag is filled with oxygen. This structure can make the aircraft carrier much lighter, and it should be no problem even if it is covered with armor.
The airbag has two small pipes, one connected to the blood vessel for oxygenation, and the other extending out of the small hole of the cortical shell. This pipe usually controls the airbag to expand to inhale when Lin floats to the surface.
Lin also made a small cell combination, which looks like a balloon swimming outside the body. The air breathers swim with small tentacles around their bodies, and the heart tentacles suck small bubbles from the water.
Qi also has a hard shell outside the body and can swallow sand to balance the body weight.
After the aircraft carrier is covered with a hard shell, it becomes more difficult to take in oxygen. When the aircraft carrier is full of oxygen, it can return to the aircraft carrier and release it. In addition, it can directly inflate the airbag when it doesn’t want to float to the surface.
However, the current situation is that although Lin has added an airbag, she has not added a body shell because the shell material is not prepared enough.
At the same time, Lin added an airbag to the guardian’s shell, but even so, it didn’t float, just to the degree of’ suspension’
In addition, Lin also protects the heart and tail layer of the guardian, which is covered with a large number of exploding balls and acid injectors, to dissolve and combine various crustaceans.
Then the combined shell will be taken out by a new arm called’ painter’ and transported to the aircraft carrier. The painter can also directly paint the shell in various places to form the shell.
Defenders are now more like shell factories.
Lynn is still considering gas to attack, but she has no good ideas at present.
The aircraft carrier swam slowly with its guardians. Lin observed that there were single cells everywhere on the beach in this deep water, whether in the gravel or elsewhere. Life here was so vibrant that it was in fresh contrast with the deserted land.
The number of single cells seems to be more than before, but there was no such scene in which the water was full of them. There were many motionless water waiting for cells to drift over to feed themselves.
When thinking like this, Lin found some multicellular creatures in front of her. They looked like tentacles of several root cutting sand pipes, and their bodies stretched out from the pipes to capture single cells floating around.
This is called’ tube worm’
I felt Lin approaching its soft tentacles and the body instantly retracted into the square tube. Lin knocked on the tube worm’s hiding pipeline and found that it was hard and must be made of shell.
Lin takes less crustaceans from food, and the crustaceans contain less than 1%. If she wants to make a suit of armor quickly, Lin must go into the gravel to get raw materials or attack those crustaceans, and this tube worm is the ideal target.
In a moment, Lin hammer severely smashed the shell of the worm.
The tube worm is thin and not very hard, and cracks appear as soon as the shell is hit.
Lin doesn’t care if the shell is hard or not, because it can dissolve and recombine the shell to adjust its ideal hardness.
Cut …
The shell of the tube worm was cracked by knocking, and the soft organs inside were exposed.
Then came the devourer workers, who brought the shell crumbs back to Lin and tore the soft body of the tube worm to pieces, recycling nutrients and shells by mistake.
The structure of the tube worm is quite simple, and Lin doesn’t even have interest in research.
The broken shells were directly sent to the guardian for dissolution and recombination, while the carrier Lin turned to attack the nearby tube worms.
