The primitive ancient snake

The big world of quicksand.

A huge city, this is the city of the Blood Wolf Clan.

Originally, this city was extremely huge, extremely lively, and brightly lit, but recently at night, every house was closed and the entire city was tightly closed. No blood wolf dared to go out.

It seemed that the city turned into a dead city at night, with no one alive walking on the streets, and even the soldiers guarding the city had withdrawn.

At this moment, in a family

"Wolf Thirteen, what’s going on? The sun has just gone down and the doors are closed. Every household has even turned off the lights to take a rest, and all the shops are closed. Isn't this your custom?"

The speaker was Hu Liu, a warrior from the Ice Tiger clan. He was very puzzled by this situation.

He came from other places, looking for his brother Lang Shisan to be a guest, and he came here for a trip, but he didn't expect to come here. After the city, he saw such a scene, extremely depressed.

This scene made him shocked.

"Hu Liu, you don’t know something. Recently, a terrifying murderer appeared in Blood Wolf City, and he will appear once night falls."Wolf Thirteen said helplessly,"It will randomly appear in a house and ask if the other person can open the door. If it cannot open the door, it will leave automatically. But if someone kindly opens the door, the whole family will die. Do not stay"

"What kind of murderer is so terrifying? If you act so arrogantly, is there no one in Blood Wolf City to take care of you?"

Hu Liu was shocked.

It didn't expect that a murderer would be so arrogant and actually commit murder directly in a huge city. This simply doesn't take the masters of this city into consideration.

"Of course I do, how could I not care?"

Lang Shisan said solemnly:"The city lord has sent countless soldiers to track down the murderer, but after months of searching, the whereabouts of the murderer have not been found.

It comes and goes without a trace, never leaving any clues at the crime scene. It only appears at night, and its attacks are extremely ruthless. Wherever it appears, any life will die.

Previously, the city lord had sent a group of masters to try to ambush the opponent, but the next morning, corpses were found all over the ground. All the masters were dead, leaving no one alive.

From then on, even the city lord was afraid and no longer dared to deal with this murderer. In the end, we could only close the door tightly at night and did not dare to go out at all.

Fortunately, the murderer seems to have his own unique rules and never opens the door forcefully. As long as we refuse, the other party will leave automatically, and now everything is safe."

"Is there such a thing? It sounds like the murderer didn't have much intelligence."

Hu Liu was amazed. The world is so big and full of wonders.

"It’s unclear, anyway, so far, no living being has seen the true face of the murderer."

Wolf Thirteen shook his head.

Dong-dong-dong!!!

At this moment, a rhythmic knocking sound suddenly sounded outside the door. Every knocking sound was like knocking on his heart, which made him feel uncomfortable. It was extremely uncomfortable.

In an instant, the hairs on Wolf Thirteen and Tiger Six stood up, feeling a huge crisis.

Then a hoarse voice came over:"Open the door, is there a kind person who can open the door? Have mercy on me, the old man."."

Such a voice seems to contain magic, making people involuntarily relax their vigilance.

Hu Liu subconsciously wanted to go over and open the door.

"Stop, don't open the door, it must be the murderer."

Wolf Thirteen caught Tiger Six, his hair stood on end, and he was frightened. He felt that he had never been so close to death.

"The murderer is coming? That's just right. Hearing this

, Hu Liu smiled ferociously, eager to try:"I wonder what kind of murderer would be so arrogant and dare to commit murder every night. He simply doesn't know whether to live or die."

Don't worry, I'm an immortal-level master with strong fighting power. I can't even kill many evil ghosts. I don't care about that guy at all."

"this!"

Wolf Thirteen was stunned. He also knew that his brother was indeed extraordinary in combat. He had saved his life several times on the battlefield. He also knew that what the other party said was true.

Whoosh!

Before Wolf Thirteen could say anything , What? Hu Liu stood up directly, came to the door, and opened the door nonchalantly.

Boom!

Suddenly, an old man wearing a black robe appeared outside the door. It seemed that his whole body was covered, and he could not see at all. It was clear what he looked like.

The moment he opened the door, it seemed that the entire house was flooded with endless cold air, as if the entire area was frozen. Both Tiger Six and Wolf Thirteen couldn't help but shudder.

"An old man?!"

Hu Liu was stunned. He didn't expect to see a weak old man when he opened the door. Could it be that what he met this time was not a murderer, but just an ordinary old man who wanted to stay overnight?!

"Thank you, kindhearted person."

The old man in black robe suddenly raised his head, revealing his empty eyes, dry skin, and scattered teeth. He smiled ferociously and grabbed it with his big hand.

"Oh no!"

Hu Liu screamed, and it let out an unimaginable scream. Its neck was grabbed by a terrifying big hand. No matter how much strength it exerted, it could not break free.

Even the power it blasted out, He was unable to cause any harm to the old man in black robe.

There was a click, and the next second, Hu Liu's neck was instantly twisted, and the life breath on his body disappeared. A master of the immortal level was crushed to death in an instant.

"not good."

The hair on Wolf Thirteen's hair stood up, and he immediately wanted to run away, but it was too late.

With a thud, the old man in black robe was extremely fast, invisible, and instantly came behind Wolf Thirteen. He grabbed it with his big hand and twisted it instantly. Broken its neck.

As a result, all life in the entire room was extinguished.

But the old man in black robe had no expression on his face, without any emotion. He was like a machine executing a program. After killing all the life here, he turned around and left.

Whoosh!

It flashed and appeared randomly in another house. It stood outside the door and knocked gently:"Open the door. Is there any kind person who can open the door? I have pity on the old man.""

The rhythmic knocking on the door seemed extremely eerie and strange in the empty and silent night, and the power of fear spread throughout the city.

…………

At this moment, a figure suddenly appeared in the mid-air of the city, looking down from a high position, holding a pen in his hand, recording something.

"Weird No. 125698, name: Knocker"

"It comes from folklore, a scary evil spirit that will kill the owner of the house if he opens the door late at night and lets strangers in."

"It has extremely strong defense and strength. It is immune to most attacks and can easily kill immortal-level masters. As fear spreads, the power of the knocker is constantly rising."

"Defense method: As long as you don't open the door, you won't die. Once you open the door late at night, you will definitely die."

"Hazard level: low."
