From entering the house to coming out.

Li Changge took ten minutes.

Mai Oda ......

After being inside for less than a minute, he pushed the door open and walked out.

When Oda Mai came out, she slowly exhaled and resumed her breathing.

Irin's couldn't help but smile.

So it seems......

The smell inside is really heavy.

After Oda Mai came out, she ignored Li Changge, who was constantly showing off her presence next to her, and instead glanced at Irin.

Although Irin didn't know what experiences and adventures the two of them had in the house, they ......

You can roughly guess it.

The old man in the house was still hiding in the dark.

An eerie gaze glanced at Irin.

It smells like a bit of scrutiny.

Irin lowered her head and thought for a moment.

It's not that hard to get into the house.

With a simple plan, Irin's come up with at least 5 options.

"Which one do you choose......

Li Changge was not far from Yi Rin, and the smile on his face became more and more intense.

It was like wanting to see Irin's joke with my own eyes.

"Hmph."

Seeing that Irin didn't move, the old man in the dark snorted coldly, and was about to close the door.

Irin smiled slightly, moistened her throat, and raised her head, staring at the vague figure in the darkness.

"From now on, let the world feel the pain......"

“？？？”

“！”

Li Changge's mouth opened wide, his face was calm and playful, and he disappeared without a trace in an instant.

Oda Mai's cold expression also showed a hint of emotion.

Rin's psionic energy level dropped a little bit as he brushed the ground.

The old man only felt as if he was "Duang" in front of him, and he completely lost consciousness!

Irin walked straight inside with a straight step.

When he passed by the old man, the old man didn't even react at all.

Outside.

Only the stunned Li Changge remained.

With his mouth open, he couldn't close it for a long time.

"? Is that okay? ”

By the time he could react, Irin had already entered the house and closed the door.

……

When Irin walked inside, he found that the light inside was not as dark as he had imagined.

Although the smell is a bit heavy, what situation has Irin not experienced?

It's just a small thing.

In the corner of the small dark room, a faint candle flame burned.

I don't know what kind of fuel is in the candle flame, but it exudes a strange fragrance.

"This tastes ......"

Instead, Irin's curiosity about the smell of lamp oil seemed to have been seen somewhere.

When the old man reacted, he was shocked to find that Irin had already walked into the house and looked around.

"You ......"

The old man glared at Irin coldly, and finally could only snort and slam the door shut.

With the help of the light, Irin's notice that the ground is littered with small objects.

In the other corner, there were scattered bones.

In the center of the scruples, there are some smashed ...... Head!

That's human bones!

So......

Irin's pupils shrank, and the small objects on the ground, judging from their luster and texture, were clearly human bones!

The broken bones on the ground were carved into various shapes, and Irin suppressed his curiosity for the time being, and did not move.

The old man dragged his rickety body to the candlestick, rummaged through the dim candlelight for a while, and after about half a minute, he struggled to find a book with a crumpled cover and threw it at Irin's feet.

Only then did Irin notice that the old man's left arm, broken at the shoulder, was neatly broken, and he had already formed a scar, and he didn't know what had happened to him.

The one-armed old man threw the little broken book at Irin's feet and ignored Irin.

There was a black rag on the ground.

It's covered in grease and dirt, and I haven't washed it in years.

The rags were spread haphazardly on the ground, and they were faintly distinguishable on them, and a word was written—

"Kill".

The one-armed old man sat down on the rag, rubbed his buttocks, and after finding a comfortable sitting position, he picked up a piece of human bone from the ground at random, and picked up a severed knife from his side, fixed the broken bone with the soles of his feet, and carefully began to carve on the bone one by one.

"Let's get out of here after that."

The one-armed old man didn't raise his head, but just said something dryly.

Irin didn't change his face and didn't feel dirty, and leaned down to pick up the broken book on the ground.

The moment Irin's finger touched the cover, the attributes of the broken book suddenly turned into words and appeared in front of Rin's eyes.

……

【Demon Killing Secret Technique】

【Grade】Rare

【Description】After use, you can learn the special passive skill [Ghost Slayer], and the number of uses is 1/1.

……

It turned out to be a skill book?

In the world, there are six levels of items and equipment.

The rarity from low to high is: Rough, Common, Rare, Rare, Epic, Legendary.

In addition, the "None" grade is a special item and is not included in the above tiers.

In the fourth layer of space, it was so easy to obtain "rare" level items, and it was also a skill book that could comprehend skills after direct use, which made Irin a little surprised.

But...... Not a surprise.

According to the information that Irin has obtained so far, this "ghost killing technique" is only a necessary condition.

As long as you're not too stupid, you can basically get the "Demon Slayer" skill.

Ghost Slaying, as the name suggests, is a secret technique used to kill ghosts in this trial mission.

In other words, the ghost killing technique can only be used to kill ghosts......

You can't kill.

However, since it is necessary to clear the customs, Irin naturally will not dislike it, and it will be included in the storage space for the time being.

After the Demon Slayer Secret Art is stored in the storage space, it turns into a delicate card.

On the front of the card, there is a delicate black thread-bound book.

On the cover is written four words: Demon Slaying Mystic.

The one-armed old man ignored Irin and remained silent, struggling to hold the bone between his toes and carve the bone carving with a broken knife.

Seeing this scene, Yi Rin knew it in his heart.

No wonder Mai Oda walked out in less than a minute.

In this way, as long as you can find a way to prove that you have the qualifications to enter the house, you will be able to obtain the skill book.

The one-armed old man will not have any other nonsense either.

As for why Li Changge spent a full ten minutes in the house......

Irin's speculation is that the guy has been tossing around the old man in the house for a long time, trying to dig out other plot possibilities from the one-armed old man.

"Heh......"

Irin stared at the one-armed old man who was concentrating on carving in the dim candlelight, and suddenly chuckled.

"You used to be a ghost hunter too?"

Syllable.

The old man who was carving the bone carving, his right hand shook slightly, and the human bones on his feet were directly broken by the broken knife.

“……”

The one-armed old man was silent, without saying a word, and picked a thigh bone on the ground again, and carved it again with concentration.

Seeing this scene, Irin smiled a little more.

He was really afraid that this old ghost hunter would not be able to enter the oil and salt.

Since there are mood swings, it's easy to do.

Yi Rin looked at the yellow candle in the corner and smiled slightly, "I think about it now, what is burning in your house is corpse wax, right?" ”

“……”

"But...... In this Ghost Fog Mountain, the most important thing is the corpse. ”

“……”

The one-armed old man moved quickly, and his only remaining right hand, holding the broken knife, quickly carved a rough outline on the human bone.

Although the one-armed old man did not react, Irin did not change his expression, as if talking to himself, and continued: "I remember that not long ago, I saw a woman in that foggy forest. ”

The one-armed old man suddenly made a move.

"Red-robed, white-haired...... It's beautiful. ”

Syllable!

The bone was broken in two in an instant!

The candle flame in the corner was windless and automatic in the house, swaying wildly and dying, as if it would be completely extinguished in the next moment.
