As the sea lung breathed, the sound of the tide rose higher and higher, as if people were in the ocean, and Si Fan could be regarded as seeing the way of life of the sea lung.

It is surrounded by abundant seawater, with basic marine features, fish, shrimp, shellfish, seaweed, mosses and the like, and almost an entire small biological chain is placed in a huge laboratory, and the bottom of this place is the sea lung.

This huge plant is constantly shrinking at the bottom of the seawater, a large amount of seawater enters it, and then erupts a large amount of seawater, which is not enough to correspond, on the tentacles in it, forming huge bubbles, this bubble continues to expand, until it reaches a limit, it breaks, and then all the gas rises.

There's a very accurate measuring instrument on it, and it shows the quality of the air inside the bubble.

Nitrogen 72% oxygen 24% These are the two main gases in the air, only the content of other series of rare gases is also shown, compared with the outside gas, the amount of oxygen rises significantly, nitrogen decreases, and the number of other rare gases is also relatively different.

However, all the things that natural gases should contain are here, but the amount is a little different.

After all, this is not the plant of this era, and in that distant era, maybe the air quality in the outside world was like this?

In short, with this number, Si Fan is very happy, but he still has doubts in his heart, because the data shows that the survival ability of this plant is still very low and grows slowly in such an environment, and when they add some substances to the water, it is their favorite to accidentally test ordinary dust and some floating objects, and when they add some elements such as land soil, this sea slung already has some super plant shadows.

Si Fan could also clearly see that the plant's breathing strength gradually increased, and the plant also changed from the first withered yellow color to the emerald green color, and finally dark green.

This transformation attracted Si Fan, and later, the researchers in the opposite laboratory proposed that in order to complete the experiment, other plants were needed to form a corresponding living environment to form the environment to which the sea lung adapted. In the end, the conclusions obtained can determine the real living environment of this sea lung.

And the follow-up experiments have not yet begun.

The environment in the laboratory is still changing, but Si Fan has already determined that he wants to release sea lungs here.

To be honest, this seems to be on land, how is it possible to grow marine plants?

Maybe only Si Fan knows that the fountain in front of this is a natural fountain, and what is sprayed below is not fresh water, but seawater, such an environment can naturally divert water, not to mention that the room itself is almost connected to the fountain, but it is just necessary to get through some of the key points.

Si Fan put the sea lung seed in the middle of the room, and then looked at the other things in the middle of the petri dish, this thing really looked very strange, the plants next to a huge seed were all cultivated plant seedlings, very delicate and tiny.

The petri dish is about 20 centimeters wide, and 80% of it is seawater, and there is air on it.

Only one plant is strange, perhaps half of it is under the water, and half of it is outside.

It is undeniable that the special style of this plant attracted Si Fan, because above him were a large number of slender tentacles, reaching into the sky, and below were constantly and rapidly spitting bubbles.

Inside the petri dish, there is a small oxygen machine that continuously supplies oxygen to the plant.

If you look closely, you can see that this thing is attached to the sea lungs to survive, otherwise there would be so much gas on the bottom of the sea for him to survive.

As for what he relied on to survive, Si Fan didn't know, it was a botanist's business.

Si Fan just looked at the plants and put the sea lungs in the room, and he didn't know what to do.

At this time, suddenly a voice came from the side.

"Knock knock!" the voice startled Si Fan, and then turned around to look at him.

That's where he came from.

When Si Fan looked over, he happened to see that the image of the sea god Poseidon had been reduced countless times and then walked in.

When he came, he squatted down and looked at the sea lung in front of him.

Suddenly, Si Fan smiled.

"Do you know this big guy?"

He wasn't going to get an answer, who knew that Poseidon actually nodded silently.

This really shocked Si Fan, this guy Poseidon is silent all the year round, never speaks, and almost ignores his existence, sheltering some people willfully every day, and then ignoring some people's worship.

Today is the first time I have seen what he is interested in.

He looked at the seeds of the sea lung, then at the other plants around him, and suddenly poked his trident on the ground as if he were crazy.

With this poke, Si Fan's eyes almost popped out.

Suddenly, he saw a large hole in the ground in front of him hammered out by his trident, and a large amount of seawater suddenly erupted from it.

The sea soon filled the room.

Si Fan, who was here, had already entered the state of swimming, and he hurriedly turned around, mobilized the system, and wanted to leave here.

But suddenly I found that I could breathe.

That's right, he can breathe, just when he wanted to order the terminator, the sea lung in front of him spit out a palm-sized bubble, which just wrapped Si Fan's cheeks, and the air breathed...... It's really not very uncomfortable.

And with the seawater soaking, the scuba seeds actually began to breathe quietly, and then spit out small bubbles one by one.

Unlike the information he had just read in the system, the bubbles of the sea slung were very large, and Si Fan doubted that he could cover himself.

And this sea lung is still a seed that has just broken through the epidermis, so there are not many bubbles released.

However, after this sea lung seed came out, it seemed a little sluggish, and there was not much spirit.

Looking at this situation, Si Fan was anxious in his heart.

Just as he was anxious, he saw Poseidon's trident poking in a petri dish on the ground.

Suddenly, the tentacle-like plants in it slowly floated to the sky above the sea lung, and then suddenly stretched out one by one weak little tentacles to touch the roof of the shed above.

Si Fan looked up, there were small caves that looked like karst caves, and Si Fan didn't know where the top of this place was.

But when the plants go up, the little tentacles are already inside.

When he saw this, Si Fan seemed to understand.

This thing and the slung are symbiotic or parasitic.

Then he saw that streams of foul water flowed from under the plant, and the sea lungs gradually turned green after sucking the sea water into it.

It's actually a group of symbiotic plants.
