The 12th case!

The demon slayer!

The moment he saw the corpse and heard the sound, Klein's hair stood on end, knowing that something bad had happened to him.

From his perspective, the living room was decorated in bright yellow. There was nothing unusual about the coffee table, sofa and other items. Only the carpet was stained with bright red blood, which was slowly spreading.

Next to the female corpse whose abdomen was completely empty was a large black dog squatting. Its mouth was half-open, revealing sharp white teeth that made people tremble. On each tooth, there was a dark red mark like rust, which seemed to be the result of gnawing on flesh and blood for a long time without regular cleaning.

At this moment, the large black dog's teeth were still tangled with bloody intestines and surrounded by dots of torn raw meat.

Its head moved over, and its magma-like eyes reflected Klein, who was dressed as a worker, and his disguised face.

"He!" A demonstrative roar came from the throat of the large black dog.

It really is an animal! It's a Sequence 6 "demon", a "demon" that's about to be promoted! And the preparations I made today are not aimed at it... These thoughts flashed through Klein's mind.

Suddenly, the black dog's body expanded rapidly and turned into a monster that was two or three meters tall. Behind it, a pair of huge bat wings slowly opened, and next to its ears, goat horns covered with mysterious patterns grew.

Red and blue flames leaped out from its wet and shiny hair, and a strong smell of sulfur spread out.

Almost at the same time, Klein kicked on the spot and swung his staff forward instead of retreating, rushing towards the demon dog like a cannonball.

Swish!

The black demon dog pounced forward swiftly, its claws covered with spikes leaving an afterimage and hitting Klein.

Silently, its claws pierced through the figure as if piercing through the air!

Klein's figure dimmed and quickly became transparent.

This is just an illusion!

It's an illusion created by Klein!

At this time, he had rolled on the ground, approached the bay window, then pressed and pushed with his left hand, and his whole body flew into the air, crashing straight into the glass.

After recognizing who the enemy was, he made up his mind to run away immediately!

When the giant demon dog saw this, its magma-like eyes suddenly brightened, and there seemed to be flames burning inside.

It opened its mouth and uttered a foul word, a word from the demon language:

"die!"

puff!

Klein's body suddenly stopped, and his heart seemed to be tightly grasped by an invisible hand.

The figure frozen in mid-air suddenly became thinner and fainter, turning into a roughly cut paper figure.

And this paper figure is covered with red rust, mottled red rust!

With two sounds of clang and snap, Klein's figure reappeared, smashing through the bay window and rushing toward the stone-clad street curb outside. His substitute paper figure slowly floated down, burning with a flame that smelled of sulfur.

The demon dog growled, pounced again, and leaped onto the windowsill.

A red fireball with a bluish tint flew out of its mouth and blasted towards the enemy's escape path.

As soon as Klein landed, he rolled over again. The red fireball with a blue tinge hit the side, but it did not explode immediately. It seemed to be affected by an invisible force and was slowing down.

Boom!

After Klein rolled and jumped for a distance, the fireball expanded and exploded, shattering the surrounding stone slabs.

Seeing the giant demon dog about to chase him, Klein opened his mouth in preparation.

He shouted at the top of his voice:

"Murder!"

"Help!"

"Murder!"

“Help!”

The sound seemed to have a special effect, and it spread far away in the quiet night, waking up the residents of the entire street and reaching the ears of the patrolmen two blocks away.

The demon dog paused in its attacking posture, and after thinking for a second, it retreated back into the room and began to clean up the scene.

Klein's running figure instantly disappeared amid the shouts of "Murder" and "Help!"

In a nearby house, the remaining charcoal in the fireplace that had been extinguished long ago suddenly reignited and emitted an exaggerated flame.

Klein appeared in the flames as if performing a magic trick, and with a light leap, he jumped out with his cane in hand.

Then, he used the "master key" to open doors and pass through walls, and quickly escape in another direction.

“Phew, at a time like this, calling for help without extraordinary powers is much more useful than simulating shooting with “bang bang bang” sounds…” Klein sighed as he took out a bottle of Amanda Hydrosol and dripped a few drops on his body.

Because the original race of the "devil" is a dog, he has to be wary of the other party's special ability, which includes tracking by scent!

He walked all the way to another intersection, where he stopped and looked around.

Seeing that it was relatively quiet here and had not been affected, he hurried to the street and hired a carriage.

Only after the carriage had traveled a long distance in the middle of the night did Klein breathe a sigh of relief, knowing that the "devil" would not catch up with him.

The "Master Key" is really weird... It actually led me to the murder scene. I have to be very careful when using it next time... It is really a "demon" transformed from an animal... Where did its magic potion and formula come from? Does it have a human companion? How did it choose its targets in the serial murder case?

Well, the good news is that after confirming this, it will be much more difficult for it to commit crimes again, and the probability of being caught will also increase greatly...

Thoughts and doubts popped up in Klein's mind, and the carriage sped along the wide, deserted road, passing between gas street lamps.

Suddenly, Klein's heart moved, and a picture naturally emerged in his mind:

Pea vines hung down from the sky, interweaving into a dense forest road, but the coachman drove the carriage unaware of anything and continued to drive over the green plants.

not good!

Klein didn't hesitate, and lunged towards the car window, ready to leap onto the street.

Bang! The carriage shook and he was bounced back.

At the same time, the pea vines really drooped down!

Klein frowned and tried to control the flames to ignite the carriage, but his finger snaps did not produce any sound.

At this time, the surroundings had become extremely quiet; even the sounds of horse hooves trampling on green plants and wheels rolling past had disappeared.

Klein tried his best to calm himself down. He looked out the window and saw that the carriage had already traveled halfway up the road woven with pea vines.

This, this is not Backlund... He narrowed his eyes.

Just at this moment, the carriage stopped, and outside the window was a hammock-like seat made of pea vines in mid-air.

A pair of feet in black leather boots dropped from there, and a soft but emotionless voice reached Klein's ears:

"What were you doing?"

It was the woman in the museum... suspected to be a high-sequence expert... She didn't seem to recognize me. After all, I used the Azik copper whistle as a disguise... She must have heard the cry for help and came to check... Klein's thoughts became unusually active at this moment.

He swallowed his saliva deliberately and said:

"I'm a private investigator, and I'm investigating a recent serial murder case with a bunch of my friends."

"I have a magical item called the 'Master Key' that can open doors and go through walls, but it will cause you to get lost."

"It was during this process that I ran into the crime scene. I was no match for the enemy, so I could only run and shout for help."

Everything I said was true... Klein added silently in his heart.

After he finished speaking, there was no response from outside for a while, but he felt a pair of eyes penetrating the carriage, penetrating the obstacles, and directly examining the items he was carrying.

Fortunately, for safety reasons, I left the Azik copper whistle and bookmark on the gray fog... At this moment, Klein was so grateful.

Being cautious and careful really does work!

After that indescribable and extremely difficult silence, a soft but emotionless female voice finally spoke:

"That key has a certain curse. Don't use it unless necessary."

As soon as she finished speaking, everything around her changed suddenly. The pea vines, the forest roads, and the path to the sky all disappeared. The carriage was still driving on the street, between the elegant iron-black gas street lamps.

Klein was worried until the carriage arrived near the East District and paid the fare of 8 soli.

—Normally, a hackney carriage would not enter any street in the East End, because it was likely to be robbed.

In the one-bedroom apartment on Black Palm Street, Klein changed his clothes and went straight to bed. He did not attempt to return to Minsk Street after midnight. With the 12th murder case, Backlund's situation must have become even more tense, and there must be various inquiries outside.

He did not immediately go above the gray fog to study the secret of the "bookmark". He behaved just as he had described to the mysterious woman just now, just a low-sequence private detective with some extraordinary abilities.

"Tonight was filled with surprises. It was quite exciting. I just stole something... Well, most of the problems should be blamed on the 'Master Key'..." Klein said with self-mockery and soon fell into a deep sleep.

The next morning, he slowly returned home, breathing in the choking and throat-irritating mist, and took the newspapers and letters from the mailbox.

After opening the door, he casually opened the newspaper and saw that the headline on the front page was as expected:

"The 12th case!"

"The devil has reappeared, and the police claim to have identified the murderer!"

…

As for the theft of exhibits from the Kingdom Museum, it was only mentioned in an inconspicuous place, and it was not even mentioned what items were stolen.

The letter without a stamp that came with the newspaper was a water bill, which Klein had to pay himself. He glanced at it and threw it on the coffee table. He returned to the second floor and boiled water for a bath.

When the mist filled the bathroom, he seized the opportunity, took four steps backwards, and entered above the gray mist.

In the majestic and unchanging ancient palace, Klein sat down and picked up the bookmark with the image of Emperor Roselle.

"It's not easy to get you!" He gently stroked the surface of the cardboard and sighed silently.
