Judgment Day [Unlimited]

Old Liang was taken aback, and quickly picked it up, only to find that it was a neatly folded yellowed note. "What's this?!"

Opening the note, Xie Xingyin felt that the rough paper was a bit familiar.I took out Keiko's diary and compared it, and it was indeed the same paper quality.

"Who tore this off?" Lao Liang's eyes widened.

Obviously, Jia Ming secretly tore out a page of Keiko's diary long ago without leaving any trace.

"You idiot!" Old Liang said angrily, "No wonder we can't find anything useful!"

Xie Xingyin frowned unobtrusively.This guy Jia Ming has gone upstairs a long time ago, so it's okay to take away the key information without saying a word, but he even left a notebook to confuse people, which is not kind.

"Hurry up, what's written on that paper? Read it to me?" Lao Liang poked his head curiously.

However, Xie Xingyin spread the piece of paper in front of him, and saw a line of letters written on it:

ULLCOZNNKXNKGJ

These letters do not look like they could form meaningful words.

Xie Xingyin frowned: "garbled characters?"

"Ah, garbled characters? No way? Brother Xie, do you not understand foreign language?" Lao Liang scratched his head and turned back to call Xiaoyan, "Hey, so what, little girl, you have to learn foreign language in high school? You can understand ?"

Xiaoyan also shook his head timidly: "I don't understand this."

Xie Xingyin looked at the messy string of letters and shook his head: "It must be gibberish, or it's an alien language."

"Hey, that's weird." Lao Liang scratched his head and said, "It's really just a line of meaningless letters? Then why does Jia Ming's grandson tear it off..."

Xie Xingyin said: "It's not necessarily boring, it's just that the content has been encrypted."

"Encryption?" Lao Liang grabbed the note and read it horizontally and vertically, before giving up, "Old Xie, can you unlock it?"

Xie Xingyin frowned: "That's enough, at least you need to know what type of password it is."

"Does Jia Ming know? When Jia Ming comes back, we will ambush him, arrest him and torture him?" Lao Liang was still coming up with bad ideas.

Xiao Lu didn't know when he came to the front, and suddenly said, "Caesar."

When Xie Xingyin heard it, his eyes suddenly lit up.

Yes, Caesar cipher.

This piece of paper was torn from Keiko's diary.Keiko committed suicide with the coin of Caesar's head in his hand, which should be the hint Keiko left for them.

Caesar's cipher is a very simple and effective encryption method. It is said that Caesar, the dictator of the ancient Roman Empire, used this method to encrypt important military information.

The encryption method is to replace the text to be encrypted with a fixed number of offsets with other letters in the order of the alphabet as a password.

For example, when the offset is set to 3, and the last 3 digits of A on the alphabet are D, then D is used to replace A.Write A as D, B as E, C as F, and so on.

After Lao Liang listened to it, he half understood: "Then do you know what the offset is?"

The number of coins in Keiko's hand should represent the offset, but with such an old photo, no matter how wide your eyes are, you can't see how many coins she has in her hand.

Isn't that useless?Old Liang was a little discouraged.

"I really don't know." Xie Xingyin said, "But if it's really a Caesar cipher, you don't need to know the offset."

Most of Caesar's enemies on the battlefield were illiterate, and they regarded this encrypted message as a foreign language they could not understand.In fact, the security of this encryption method is very general, and people who know a little about it can completely crack it by brute force.

The maximum offset of the alphabet is 25. Use the enumeration method to try one by one, and find a meaningful combination to solve it.

Xie Xingyin picked up the pen and began to try one by one.

1 is wrong. 2 is wrong.

3 is not right either...

When he got to 6, there was finally a decent line of letters listed on the paper.

"It should be this."

Lao Liang probed over and saw a line of letters neatly written on the paper.

OFF WITH HER HEAD

"I don't understand foreign language, what does this mean?" Old Liang asked.

"The Red Queen's famous saying - cut off her head." Xie Xingyin stared down at the yellowed paper.

"No, whose head is this going to cut off? Is the human-faced dog Jia Ming or Li Wei?"

Lao Liang was still in the fog, and was about to ask questions, when a short scream came from outside the door.

"what--!"

The four of them turned around and rushed out to have a look, only to see Xiaoyan's two female classmates standing outside the elevator car with terrified expressions, not knowing what they saw.

The unmanned elevator door slowly closed again.Xie Xingyin pushed aside the others and stepped forward, pressing the switch.

The elevator opened with a "ding".

In the elevator, Jia Ming's pupils were gray and loose, and he was dead.He was still holding the town house talisman at the door of room 1404 in his hand, and there were two blood holes on his neck, as if his throat had been bitten off by something.

Xie Xingyin's expression turned cold: "Not good!"

He turned and rushed out of another room, this time breaking in without waiting for a knock.

Li Wei's room was completely silent, and the "patient" who was supposed to be resting in the room disappeared.

The room was dimly lit, with curtains blocking out the moonlight.Xie Xingyin walked to the window and pulled open the heavy curtains——

The wind blows in.

There is no anti-theft window.From this window it is easy to climb out and jump onto the platform outside.

Xie Xingyin was silent for a moment, then suddenly turned around and left.

Seeing that his complexion was not very good, Lao Liang hurriedly held him back: "Wait, are you sure it's Li Wei now, why don't we observe again?"

But Xie Xingyin said: "No need, I suddenly remembered that there is still one of us who hasn't asked."

"Who?"

"Keiko."

When Lao Liang heard this, his jaw almost dropped: "What? That, that, is that a ghost!?"

But after thinking about it, it seems quite reasonable.The Human-Mask Dog will not tell them what happened in this apartment, I am afraid only Keiko knows.

They found hints in Keiko's diary, but apart from that page of passwords, all she left in the diary were invalid information, as if to cover up people's eyes and ears so that no one would find out.

Keiko seems to be hiding from the dog.

The other two girls stood in the distance without knowing it, watching them vigilantly crashing into Li Wei's room, and then ran out one after another.

Xie Xingyin had no time to take care of them, so he took Lao Liang, Xiao Lu and Xiao Yan, and the four went straight to the 14th floor.

When they walked to the door of 1404, they found that the door was open, and the talisman paper pasted on the door had been removed.

Lao Liang couldn't help feeling sorry, shook his head and sighed: "Oh..."

Since Jia Ming had already gone upstairs, he thought he was smart and refused to listen to their advice, firmly thinking that Xie Xingyin had some ulterior secret to hide from him.

So Jia Ming ignored his advice and went upstairs alone when no one was around, and then an accident happened—he was bitten off by the human-faced dog before he could even struggle.

This is not called being smart but being misunderstood by cleverness, this is called 24k pure stupidity x.

"Oops." Xie Xingyin said, "Old Liang, you said that the spell outside room 1404 is for suppressing ghosts, right? The spell was removed by Jia Ming, did the female ghost run out?"

Lao Liang slapped his thigh and quickly took out the compass.Turned left, turned again, turned around the whole room, the needle of the compass did not move.

"It's broken, it's really gone." Lao Liang spat.

"This apartment is so big, where are we going to find her?" Going around and returning to the original point of finding a needle in a haystack.

Really tricky.

Xie Xingyin walked around the apartment twice, and stood still at the door of the bathroom: "Actually, there is one thing I can't figure out. If Keiko is dead, where is the body?"

The corpses of other apartment residents are in the room, why is Keiko's body not there? "

Old Liang opened his mouth: "Then what do you mean?"

Xie Xingyin stared at the dark hole.

"The female ghost came out from there, I want to go in and have a look."

Hearing what he said, the hairs of the others stood on end.Xiaoyan folded her arms and got goosebumps all over her body: "Don't, that might be her lair..."

"Wait." Lao Liang took his compass and looked around, making sure that the pointer was not moving at all, and restrained his expression.

"There is nothing in it for the time being, thank you, go and come back quickly."

Now there is no other way, they can't let go of any suspicious places.

Xie Xingyin crawled in with the flashlight in his mouth, and quickly found the upward passage.

The entrance of the passage was a bit narrow, and it was barely possible for a thin female ghost to get in and out, but Xie Xingyin, a big man, couldn't climb up, so he had to use a flashlight to look up.

But after a long time of exposure, the entrance of the cave was like a black hole, and nothing could be seen, and it seemed to be empty inside.

Xie Xingyin adjusted the angle of the flashlight, turned sideways and vaguely saw something in the shape of a scroll.Cautiously, he reached in and fished it out, and pulled out a newspaper.

When I opened it, it was the missing May 5nd edition of the newspaper.

found it.

Xie Xingyin took a deep breath, and crawled backwards again.

The others gathered around the entrance of the cave, watched Xie Xingyin come out, and came up to give him a hand. "Old Xie, what did you find?"

"I found the newspaper on May 5." Xie Xingyin slipped the newspaper to Lao Liang.

Lao Liang opened his eyes excitedly, and saw the column of front-page news at a glance.

Lao Liang read for a while, his face turned green visibly, then he swallowed tremblingly, and raised his head.

"The day after Keiko committed suicide, rescue efforts failed and she was declared dead. The body was pulled into the morgue, but she came out of the morgue that night..."

"Keiko walked out of the morgue with a stiff expression, but she was clearly a real person. The police could only say that the hospital had misdiagnosed her, so Keiko went back to Wangchuan's apartment..."

Xiaoyan, who was closest to him, suddenly shuddered: "What, Keiko died? Then who came out of the morgue later, she, she, she can't really be resurrected, right?"

"It's a human-faced dog." Lao Liang folded the newspaper back with trembling hands, "Thank you, you are right, then we must go find Huizi's ghost now."

Xiao Lu asked him: "Aren't you a Taoist priest? Do you know spiritism?"

"Well, no." Lao Liang rubbed his nose and said embarrassedly.

Xiao Lu cast a look of contempt at him, so Lao Liang tried to argue for himself with a puffy face, "No! What kind of spirituality is there! There is no fucking ghost in the real world! It's nothing more than scaring you children. thing!!"

"But there are in this world." Xiaoyan said weakly.

"Tsk, let me think about it, let me think about it... rhino horn, crocodile tears, or a magic summoning circle?" Lao Liang thought about it and said a few things that were said to be used for psychic communication.

Xiaoyan stroked his short hair, and frowned his delicate eyebrows: "But where are we going to get rhinos and crocodiles?"

Old Liang scratched his head: "I don't know about that."

Xie Xingyin stood beside him without opening his mouth, but now he actually said: "I know an easy way."

"What way?" Others looked at him one after another.

Xie Xingyin explained: "Have you heard of the four-corner game?"
