Junior sister, she reached the pinnacle of life by picking up rags

The gray matter above the Lianheng Meridian could no longer automatically exchange with the airflow when it came out of the Endless Abyss. Yan Yun didn't understand it at first, but now think about it, it must be because the world outside her Endless Abyss lacked a kind of air.

A kind of air that is unique to the Endless Abyss. Yan Yun guessed that this air is most likely black air.

But now this gas is not fully mature yet, so let's call it gray gas for now.

But why must gray matter be formed in order to absorb spiritual energy? Then there is only one answer, spiritual energy and gray energy, there can only be one.

The gray matter is to block the invasion of black air, but at the same time, that layer of gray matter also needs to absorb black air to consolidate stability.

Seeing that she didn't move for a long time, Duocai guessed that she was worried about something, so he spoke again.

"Forget it. Don't I know you? Just do what you want to do. I tell you, everything will be fine." Although its tone was a little depressed, it was not the persuasion that Yan Yun expected, nor was it a cold blame, but an understanding that was beyond her expectation.

Yan Yun nodded and she disappeared into the spiritual vein.

The underground is not dark. Under the illumination of spiritual energy, the entire underground is like a fairyland or a dream, so unreal that it seems fake.

She was isolated from the spiritual vein, with an invisible and intangible wall blocking her way.

The spiritual energy cannot get out, and the gray air outside cannot get in.

But all this is not a difficult task for Yan Yun. She just needs to figure out why spiritual energy is harmful to living things here?

She needs someone to help her verify it.

Yan Yun was walking underground. It was impossible to find people here, but he could definitely find monsters!

She picked up a fat, hamster-like monster that was sleeping soundly and brought it to the wall.

The little elves blinked their cute big eyes and were not afraid of her, because even Yan Yun had not realized that after truly integrating into this world, her aura was extremely gentle and full of vitality.

This feeling is like the bamboo joints that come alive and grow taller after the spring rain.

Yan Yun gently rubbed the elf's furry head with his fingertips, then placed his fingertips on the wall, feeling the intersection of qi with his heart.

She slowly channeled a trace of spiritual energy into her fingertips, attempting to attract the spiritual energy and then break the confinement of the wall.

Although the spiritual energy did not seep out of her body, it caused her spiritual veins to become restless all the time.

Time passed by minute by minute, and when Yan Yun almost thought he was going to fail, a barely visible trace of spiritual energy broke through the invisible wall, but it did not come towards Yan Yun.

Instead, it rushed directly into the body of the elf.

Everything happened so fast that Yan Yun frowned slightly and stared at the goblin nervously.

At first, it was fine and looked like nothing was wrong, but after half an hour, it started to become listless and lacked any energy. Yan Yun could clearly feel the disordered breath in its body and the gray air running around.

Seeing this, she turned into gas again and devoured the spiritual energy in the little monster's body with her brutal momentum, and the little monster slowly recovered.

She understood that if they only lived in a world of gray air, then for the creatures here, it would be safe and without danger. But once the gray air and spiritual energy met, neither would give way to the other, and the gray air would begin to devour life.

This also explains why, after the mine exploded, the black gas devoured life so crazily. At first, Yan Yun thought that this was its characteristic, but now it seems not to be the case.

Then, she thought of Lian Heng again. Perhaps she could first think about how to create that layer of gray matter and attach it to the meridians.

Yan Yun naturally didn't need it. Her meridians were tempered by ice flames and nourished by spiritual energy, so even the black air could hardly invade.

The next question was, what is gray matter? The first thing she thought of was the air that circulates in the air.

Although she didn't know whether it would be right or not, it didn't matter. She could give it a try. If it wasn't right, it wouldn't be a loss for her.

Then, icy flames emerged from her brows, and the little monster was so scared that it hid in her sleeves. Seeing this, Yan Yun gently put it on the ground.

She wanted to refine this energy.

Refining requires a refining furnace, but ice flame is the most spiritual fire in the world, so what if you refine it with bare hands?

Yan Yun had almost no experience with these things, but she thought that since it was refining, the principle should be similar to the condensation of water mist into ice.

Because of this, she was briefly in a difficult situation.

For a moment, she thought of many methods, but she really needed to find a test subject. She looked at the confused little monster on the ground, waved her hand, and told it to go back to sleep.

Yan Yun manipulated the ice flame and released a ray of fire. The flame released by the ice flame was not hot, but icy cold, with a chill that swept across everything.

The surrounding gray air was forced to gather together, and Yan Yun continued to compress it, lowering the temperature to an extremely low level. The entire underground was icy and covered with frost in an instant.

The gray gas under her control had almost nowhere to escape. She pushed her control over the fireworks to the extreme, trying again and again, failing again and again, and continuing again and again.

The sweat on her forehead turned into a thin layer of frost. The faint blue light emitted by the fireworks made her look as cold and desolate as ice and snow.

As time passed, a gray pill-like object appeared in the scorching ice flame.

At this time, Yan Yun slowly stopped and retracted the ice flame. The moment she stopped, she almost fell down. Without the replenishment of spiritual energy, this refining process consumed too much of her energy.

She slowed down, looked at the ground which had become an ice cave, and searched around for the little monster.

The little elf's body was a little stiff from the cold, and he was huddled in the grass nest. When he saw Yan Yun coming, he quickly turned over his soft belly and faced her, his pure eyes full of love and admiration.

"Feel sorry."

Yan Yun felt a little embarrassed, so she bent down and placed it in her palm to provide warmth for it. After its body warmed up, she took out the gray pill.

She stuffed it into the little monster's mouth. She felt a little worried and was ready to save the little monster at any time. She waited with her bright and powerful eyes without blinking.

The pill melted in the mouth, and the refined gray gas directly penetrated into the meridians of the monster, firmly attached to the meridians with a strong posture, wrapping it layer by layer.

There was no discomfort on the little monster's face. Seeing this, Yan Yun breathed a sigh of relief, but more questions followed.

If one were to directly cultivate this Qi into a physical entity, the control of temperature and air pressure would be extremely strict and complex, which would be too difficult.

What is said here is too difficult, but it is for the people here.

Although this is difficult for Yan Yun, it is not difficult after becoming proficient. It just takes more time. However, all this is based on her ice flame.

So is there an easier way?

This method is so simple that it doesn't require any brains. Although it sounds far-fetched, Yan Yun really needs this method.
