Lu Bufan was walking on the bottom of the sea.

Funnily enough, he carries a large stone slab on his back.

This is used to strengthen the body weight, otherwise, it will float up.

If you look closely, he doesn't feel any stuffiness.

It's as if he is a fish in the sea, able to breathe in the sea.

But in reality, he doesn't have that ability.

He just let his soul antenna extend out of the Baihui acupoint, and then turn around and pass through his mouth, and then extend all the way to the sea. And his soul antenna has also undergone a special change, becoming many times larger, and it has become hollow.

The air flowed through it and into his mouth.

It's like he's holding a hollow tube.

So, he doesn't have to worry about lack of oxygen.

Now he has a huge doubt in his heart, that is, if the alien does not have enough oxygen, how can Lu Ritian survive?

And this was originally an important secret method that Lu Ritian wanted to teach him.

It's a pity that Lu Ritian left only one sentence in his memory, "Taoism is natural!"

Let him figure it out and solve it for himself.

This question is very important to Lu Bufan.

And this time, he's here to solve this problem.

He just wants to understand what Taoism and nature are, so that he can survive in a place where there is no air or oxygen.

Now he has cultivated to the level of strength.

The Sea of Souls was already filled with liquid made of soul energy.

It's not too big, just the size of a basketball.

In other words, his soul sea is also a space the size of a basketball.

If he couldn't break through this space, his soul wouldn't be able to grow again.

Even if he used jade to cultivate every day, it would be of no use.

Then if he wants to cultivate to the second grade of strength, there is almost no possibility.

And the soul sea has magical spatial characteristics, there are nine layers, and when the soul is strong, it can break through the first layer, then the second layer, and the third layer......

But the way to break through the first layer is to understand the mystery of how to survive in a place where there is no air.

He believed that once he broke through the second layer, he would soon be able to cultivate to the second grade of strength.

He had seen many geniuses in Jinghua Genius University, who were about the same age as him Lu Bufan, but three of them had cultivated to the third grade of strength.

He had to catch up.

Lu Bufan is puzzled, the Tao is natural?

What a.

I am a human being, not a tree, nor a grass.

You can't turn carbon dioxide into oxygen.

Moreover, even trees and grass can't survive without air, right?

I thought that at the bottom of the sea I would be able to trigger inspiration and comprehend mysteries.

But it almost didn't suffocate him.

He had to let the Soul Antenna come to his aid, sustaining what he needed.

Then he will have more time to think and perceive.

He saw a lot of fish.

Various.

He even encountered a school of sharks.

But there are no dangers.

After all, now his soul antenna can sense a 300-meter area around him, even in the water.

He can dodge at any time.

Moreover, he can hypnotize sharks and turn a blind eye to him.

Of course, he was also ready, with a dagger in his hand.

A big war can break out.

With his speed and combat power, he is not afraid of sharks.

He didn't study the sea fish carefully because it didn't make much sense.

Marine fish also have to absorb oxygen from the water to survive.

Even if you can go to a place where there is no air and oxygen like a fish in the sea, you will die.

Therefore, the Tao is natural, and the sea fish is not the object.

He encountered a lot of aquatic plants, and finally sat down in front of a piece of kelp, carefully observing and feeling.

"Kelp is the same as plants on the ground, it absorbs carbon dioxide and then releases oxygen......"

Lu Bufan's mouth muttered, "If I have the ability of a plant and can turn carbon dioxide into oxygen, then I should be able to survive in a place where there is no oxygen, but if I go to space, where can I get carbon dioxide?"

His face was full of doubts, but he vaguely felt that Lu Ritian had let him teach the way of nature, and comprehend the mystery of surviving in a place where there was no air and oxygen, which must be related to plants.

He stood up and moved on.

Slowly, he didn't know where he had gone.

Finally he came across a small island.

And he climbed up.

The island is overgrown with small trees and weeds.

It's verdant and looks vibrant.

The sea breeze blows, setting off green waves.

Wrapped in the scent of the sea.

Very comfortable.

Lu Bufan sat on the grass, his two eyes looking directly at the grass on the ground.

My heart is full of twists and turns.

Ancestor Lu Ritian sent out new seedlings from the root system of the dead tree and comprehended the mysteries of the True Immortal Secret Codex, so that he could live forever.

However, he didn't teach me all the exercises, but after leading me into the door, he went to comprehend it himself, and if he couldn't comprehend the key mysteries, the specific exercises he practiced later would not be displayed, and he would be blocked all the time.

Ay......

How can you survive in a place where there is no air?

He thought about it for a long time, and suddenly an idea flashed through his mind, "Why should I want to survive in a place where there is no air? The road should be walked step by step, and the meal should be eaten in one bite. ”

Then he became excited, and his mouth was also muttering, "The Tao is natural, hehehe...... As long as I have the ability to these grasses, I'm done......"

Through the soul antenna, he observes the grass on the ground in all directions.

In the end, he realized that he was a human being, and it was impossible to have the ability of Xiaocao to turn carbon dioxide into oxygen.

However, the body can't become grass, but the soul can.

After all, the soul is ever-changing and has super plasticity.

Didn't you turn your soul into a radio that could pick up the voice of someone who could use the wavelength of your soul?

Isn't it easy to turn into grass?

He immediately began to excitedly transform his soul,

First, let the soul antenna extend out as long as 10,000 meters.

If it grows longer, it can't be controlled, and it will collapse.

Therefore, there is a lot of space in the soul sea.

Even so, he couldn't continue to absorb jade energy to cultivate.

If the sea of souls is full, the antenna will not be able to be collected.

You can't hang out with such a long soul antenna.

The soul antenna is black and can be seen as long as you are not blind.

That might be considered a youkai.

Then, Lu Bufan began to carefully manipulate the soul energy of his soul sea.

Slowly it turned into a grass, then two grasses, and finally a meadow, which came to life.

It's exactly the same as the grass on the ground.

Even, there is a root system.

But because it was in the hard sea of souls, there was no way for the roots to sink into the dirt.

However, it seems to be of little use.

There is no breakthrough in the bottleneck at all.
