Fang Nuo didn't know exactly how long he had spent underground.

During this time, he dragged his long arm for a while, kicked open the lid of the nearby wooden box, and looked at the soul crystals inside that were older than some of the Yellow Immortal Elders; For a moment, leaning against the red brick wall, he closed his eyes and tried to digest the information that poured into his mind after taking the old lady's life.

By browsing through the memories that didn't belong to him, Fang Nuo discovered that there were actually hidden passages around the "end room".

Over the past decade, adventurers from outside the mountain village have often broken into this underground project by chance.

And they either died here, or they "took it when they saw it", and left in a panic without going too deep.

Later, the witch arrived, and the secret passage for humans from the outside world was sealed overnight, and the "treasures" hidden in various parts of the underground project were also collected in the room at the end.

However, although the human adventurers could not enter, the orcs still had a way to find the location of the secret passage and sent their dependents to explore the way.

But their wishful thinking ultimately fell through.

The secret passage could not help them enter the underground project, so that the orcs led by Naga could only search for the "main gate" of this place through the human inner response in the mountain village, and no longer tried to find another way.

However, after researching, Fang Nuo suspected that although the Dark Passage could not let humans or orcs in, it could help them leave.

The snake probably escaped from under his nose by sneaking into the so-called "secret passage".

"The breath of miracle that I perceive...... he touched his nose, which had become very unfamiliar, "I'm afraid it's not some kind of escape specialization, but the breath left after the beast clan absorbed the spiritual power in the soul crystal." ”

He guessed that Naga's trip was to find a specific treasure from the beast's collection, so the other party would ignore the remaining treasure in the red brick house.

There are thousands of orcs who lost their lives in that beast tide 11 years ago, and maybe some of them are Naga's relatives.

Perhaps, the deceased snake demon beast happened to be carrying the "treasure that helped the snake clan molt into immortals".

"He doesn't care about the other treasures at all." Fang Nuo picked out a relatively intact soul crystal from the wooden box, "Although many of them are broken, all the spiritual power stored in them has been released, mixed with the surrounding resentment. ”

"But there are also some intact crystals, if you take them like Xiong Zhen, the spiritual power capacity in the body must have increased a lot."

Fang Nuo picked out a few white soul crystals and placed them side by side on the floor in front of him.

When he first learned about the concept of "soul crystallization", the mourning birds warned him not to rashly devour these spiritual power condensations that belonged to other demon beasts.

They carry the will, thoughts, hatred and resentment of those who have passed away.

Keeping them in your body without any protection can easily erode you and slow down your promotion to a great extent.

"Tsk."

Fang Nuo gathered the crystals on the ground together, struggled to stand up, and finally managed to maintain the balance of the body, and then, forcefully pulled out half of the brick on the wall next to him, and smashed it to the ground.

The pure white soul crystals immediately shattered.

White spiritual power escaped from it and blended into the surrounding atmosphere.

Under the purification of the angel umbrella, they were not immediately affected by the resentment in the air and deteriorated into black or red spiritual power, but gradually faded and finally became the most basic colorless spiritual power.

"Purifying ......" is what Fang Nuo called this phenomenon.

Through this "process", although the will of the deceased in the spiritual power still exists, it will no longer enter their bodies as the demon beast swallows the atmospheric spiritual power.

However, what the Angel Umbrella can do is only "simple purification", and even if the spiritual power filtered by it does not carry the thoughts of the deceased, it will take more time to absorb them.

It was much more laborious than absorbing ordinary atmospheric spiritual power, Fang Nuo thought to himself.

But these spiritual powers from soul crystals have always existed in the bodies of demon beasts in the past, and they can be extracted and used by them at any time, constantly running and circulating in their bodies...... They were far purer than the ordinary spiritual power contained in the atmosphere.

Although the absorption time is longer, the steps of screening and removing impurities are omitted, and the overall time is really shortened.

There are elders in the clan who have mastered the most advanced purification techniques, and with this skill alone, he can live under the protection of the family without improving his strength.

The pure spiritual power created by him is specially provided for pregnant women and newborn children, the former is not strong enough to purify the spiritual power in the body, and the latter is too small, and the spiritual power that absorbs too much impurities is easy to die early.

For demon beasts, absorbing atmospheric spiritual power does not need to be "learned", it is an "instinct" that is directly comprehended by birth.

However, skills such as "how to absorb more efficiently", "how to maximize the application of spiritual power contained in the body", and "how to reduce the impurities precipitated after purification" need to be taught and learned by the elders.

Fang Nuo raised his shriveled arm and stretched out to a place in the air with dense spiritual power, and soon, the invisible spiritual power attached to that arm, causing it to swell up slightly, becoming somewhat in line with his aesthetics.

It's not good that the monster beast is too thin, it doesn't look like it will live long, and it will be easily eliminated by nature, he thought.

But after a while, it deflated again, and it looked like it was leaking.

Fang Nuo sighed helplessly, casually picked up a piece of broken crystal on the ground that could reflect his image, and carefully compared the difference between his current self and the "ugly monster" not known how long ago.

Well, the hair is shiny.

Face...... It's still like a grimace, the skin is wrinkled, and the facial features don't seem to be unfolded.

He knew where he had seen this face—wasn't the old human lady the basis for his transformation?

He killed Lady Iris and thus gained the ability to transform into her.

He didn't want that!

It's the hand of the forest greenstone, not himself...... For unknown reasons, Fang Nuo suddenly felt a little aggrieved in his heart.

The thought of his cherished stone made him even more sad.

The "three chances" that were guessed before are now only one time left, is there a way to restore a treasure that has lost energy to its original state?

There are so many rare things in this world, and he believes that there must be such a way to reuse treasures that have completely lost their effectiveness.

He had tried to "construct" the answer to the question with his own abilities...... Unfortunately, the malicious value of "omnipotent" does not seem to be able to be used in this regard.

However, thanks to this underground engineering venture, his "savings" were suddenly abundant, and he did not need to save them for a long time to come—though he never considered saving them.

When you get back, plant the oak tree, let it ripen, and make the witch owe her a favor!

Turning the "mirror", Fang Nuo noticed that on both sides of the old lady's ugly face, there were "strange things" that looked like thorns and resembled the characteristics of some kind of demon beast.

Huang Xian didn't grow like this, he was a little puzzled.

Sure enough, it was his poor deformation ability that caused even the old lady to become bad?

The black "thorns" are a bit like the horns of the "elven deer" that often wander around Huangxian Ridge, except that they grow on the head of the deer, and these strange things are born from the side of his head......

I broke them, but they didn't move, but they didn't feel any pain.

It was a pure aberration, and he looked down to see his own twisted feet, covered in a layer of scales, with long, pointed nails.

He glanced at the nine long, short tails behind him, the same color as the messy hair on his head.

"Alas......" Fang Nuo's mood became even more depressed.

The condition of the tail has improved, and you can see that one of the tail tips has turned black, and the others are also shortening and disappearing...... As for other parts of the body, at least, you will get used to it after watching it for a long time.

"Ahem, ahem, well, ahem!"

After absorbing the spiritual power that had been simply purified for a while, and leaning cross-legged against the wall and closing his eyes and practicing for a long time, Fang Nuo stood up again and cleared his throat, intending to practice his pronunciation.

With the help of his own ability, he constructed a herb that could be used to moisten his throat, and slightly relieved the discomfort in his throat.

Bored, he drew on the ground a character that he had read in a human book, and read the corresponding sounds from memory.

Of course, without someone else correcting it, he didn't know whether he was reading right or wrong.

"I—of, name—"

He thought back to what he had learned in his family and planned to practice introducing himself to the air.

"Yes......"

What is it?

Fang Nuo suddenly realized that he did not know the corresponding pronunciation of the name "Fang Nuo" in human language.

He only knew how to elaborate it in the language of the Yellow Immortals.

And, because he had never told his clan about the name that appeared in his self-perception, he didn't even know the human glyph that it corresponded to.

Only the vague outlines in the brain may be the words used by humans, and it may be those of other races that have the concept of "words".

What's more, the writing used by human beings is not only the one he is commonly used in, and outside the mountain village, there are many human kingdoms, and some of their cultures are very different.

After thinking about it, Fang Nuo, who was becoming more and more distressed about this matter, carved the outline of the glyph in his head on the ground with his pointed nails.

"What a trouble...... he lamented, falling backwards.

The moment his back touched the ground, he suddenly realized that the hair on his body had grown back.

Great, he thought, he didn't look like he had a skin disease.

On the thin arms, white fluff gradually grows.

His mood brightened a little, and at this moment, a rush of footsteps, from far and near, quickly rushed towards his place.

It sounds familiar.

NOKA? The little beast that had not yet released its transformation immediately rushed to the door, pulled the stone door tightly, hesitated for a moment, reached out and pulled the nearest wooden box to him, and pressed it against the door.

Then, he sat directly on the wooden box, leaning his back against the door, silently listening to the movement coming from behind him.
