On the originally flat land, now a high hill is bulging, overlooking the two small evolutors on the ground.

Everyone could see that there was something huge, which was about to drill out of the ground, but stopped at the moment before it was about to break through the earth. Thick layers of soil, rocks and plant clumps vaguely covered the behemoth under the night; The warehouse, which was still lit, was leaning askew on the earth slope, and the walls creaked, and it would crumble and roll down at any time.

The body that was still hitting the room just now was submerged by the open land and disappeared.

"What... What?" Long er staggered back a few steps. "Do you know what's under the ground?"

Lin San Jiu didn't look back, but said "Hmm" quietly, "I guessed a little more than I knew."

"What did you guess? Is that what you just said about the copy?"

As if hearing his words, the sound of stone friction suddenly tore the night sky.

"Please announce the unlocking of the chamber of secrets... I really, ah, need a piece of scalp very much," the voice of the copy is like a messy recording mixed with other content. For a moment, it is a smooth and clear explanation, and for a moment, it is singing an unpleasant song out of tune: "piece by piece, scalp and hair, neat... Please announce the process of unlocking the chamber of Secrets immediately."

"... what a chaotic guy."

Lin Sanjiu sighed, looked at the hillside and the precarious warehouse in front of him, and pondered for a while. Teacher Yi's voice was almost sharp and quickly connected into a line: "what's going on? What's under the ground? What's wrong with the copy? Hurry up and say it from the beginning. Don't sell!"

Before the voice fell in his head, the earth suddenly shook up again, and immediately threw long er down a somersault; Countless mud and stones thump on the warehouse wall, and then roll to the ground - the hill like shadow rises higher and larger, and the dark outline gradually withstands the night sky.

"Please players..."

"Wait, I'll start now!" In the tremor of the earth, Lin Sanjiu hurriedly stabilized his heels, raised his head and shouted. Long er sat on the ground, staring at her in a daze.

"Watch it," she shouted without looking back, A pair of eyes only stared at the dark shadow of the rising hill in front of him: "don't you really want to know how to form this secret room? The fact is actually very simple. After the prisoner killed, he put the dead man's pants somewhere in the warehouse and put the string of keys into his pants pocket. He took the dead man's coat and walked out of the warehouse, just like what I just did... Then he locked the door from the outside."

"Eh? How did he lock it?"

"Use the key. He just took out the key of the warehouse."

With a sob, the hill like shadow suddenly vibrated, and the warehouse was oppressed to make a groan like sound. Finally, several pieces of broken walls fell down, "bang" hit the high dust. Lin Sanjiu moved back a few steps, carried his back in a hand behind him, and quietly called out a card.

"Since the prompt is a secret room, it means that the deceased has the only key. From this point of view, it may also be the reason why the murderer wants to make the death scene a secret room... If the warehouse keeper doesn't show up for several days, it must be very inconvenient for the company. Maybe it's strange, maybe it's because he wants to go in and get the goods. In a word, other people entered the warehouse with strong means, and one of them is the murderer."

When Lin Sanjiu said this, he gently waved the card in his hand, and there were many figures in the night - the painter placed the paint bucket, supported the easel and the toilet in an instant, but held up a pen and didn't move.

Because she hasn't chosen the "object".

"This is also the reason why I suspect that the murderer is a colleague. After the murderer broke in openly, the murderer just had to find a chance to put the warehouse key back." Lin Sanjiu glanced at longer,

The young man just opened his mouth at this time, with a suspicious face: "it's so simple? Isn't it?"

"What's wrong?"

"After he put the key away, he came out and shouted that he was dead. Wouldn't he become the first discoverer of self directing and self acting? Once he realized that this was a secret room, he was the first suspect of the police."

"The simpler the plan, the more difficult it is sometimes to see."

Lin Sanjiu waved to long er and motioned him to come closer: "... If I tell you, the murderer didn't enter the warehouse alone, nor was he the first discoverer?"

"No?"

"Generally, if you need to enter the warehouse, it's all for the purpose of moving goods? Besides, in order to make yourself not suspect, the murderer will probably enter the warehouse with several other people." Lin Sanjiu squinted at the cement house on the earth slope, Soft channel: "He doesn't have to find the body at all. From the perspective of clothes, it was autumn and winter when the crime was committed, and the smell of the body may not be strong. In addition, the body was hidden in the depths of the warehouse, so he just took the opportunity to find the jeans before others found the body, and hung the key back on the key chain. As long as the distance was not very close, it was not easy to be detected by people fiddling with a piece of clothing in the warehouse full of clothes. This was the first one he had to take off The reason for dropping the victim's clothes. "

After a while, long er was still not convinced.

"I still think it's too simple... It's very unnatural to take off the victim's clothes. When others see the key in the jeans they took off, they may also think that someone put it in later."

"There is a way to ensure that everyone will not think so."

"What can I do?"

"This is the second reason for taking off the clothes of the deceased. The killer deliberately placed the jeans in a corner. After a few days, a thin layer of ash will accumulate on the jeans and the surrounding plane. As long as he is prepared in advance, such as raising the iron ring of the key chain a little and exposing it, he can hang the key and push it back without touching the pants, so the ash around the pants will It shows that this pair of pants has not been moved in a few days. "

Long er opened his mouth and couldn't pronounce a word.

"But, after all, the iron ring cocked up..." after a while, long er frowned and said, "is this also a doubt?"

"No, this is a very common trivial matter in daily life. And the murderer made a cover up, making people subconsciously think that the lifting of the iron ring occurred before the death of the dead."

"Eh? What is it?"

"That small window key." Lin Sanjiu pointed to the coat on the ground, "it was taken down alone and put in his pocket with the deceased's employee card. When anyone saw it, they would subconsciously think that the key ring was loose, so the deceased put the dropped small key into his pocket?"

"Ah, it really makes people think so." Long er suddenly realized, "but when you take your coat out of the copy, it means that the murderer also took the coat away. What's going on?"

"When I opened the door, I didn't step out immediately. Do you remember? Because at that time, I could strongly feel that I lacked a condition to go out, so I stopped and thought." When Lin Sanjiu said this, long er looked dazed, and obviously didn't realize when she stopped to think - "then I found that the window key in my pocket, in addition to suggesting that the key ring was broken long before the victim died, had a separate role."

"What, what role?"

"It provides a continuity for tops and pants."

"I... I don't understand."

"The general assumption is that the deceased found the window key missing, so he stuffed it into his pocket. After he was killed, when the clothes were taken off, a large number of keys were left in his pants, and the window key was still in his pocket. Do you notice? The key is like a thread, connecting the time when the coat and pants were placed in the warehouse. With it, you will not doubt that the coat was put into the warehouse on the day the body was found. ”

"Ah?" Long er was surprised, and even couldn't care about the dark shadow of the hill not far away: "why did the murderer do this? How did he do it?"

"Put it under your coat, take it in, and then take it off." Lin Sanjiu shrugged his shoulders. "As for why... I think the murderer must have a motive to take it away. It's likely that he wants to deal with some evidence."

But this is all speculation, there is no evidence.

"But there is no ash on the coat..."

"Don't forget, this is a clothing warehouse," the commentary was at the end, and she stared at the hill again: "just stuff it between other bags. Under the cover of the shelf, if you move quickly, you can finish everything in a minute or two, then say hello to your colleagues and leave first... When someone really finds the body, come here with the spectators. Who else would doubt him?"

"Sure enough, sometimes the simpler it is, the harder it is to think of." Long er sighed, and his expression was a little satisfied, like reading a novel; But the satisfaction flashed away, and changed into a low and depressed look: "but... What is under this mound, you haven't said yet?"

"Hey," Teacher Yi suddenly shouted, "your car has been driving long enough. If you drive it further, your consciousness will be exhausted."

Well, anyway, all the problems that should be considered have been considered.

Lin Sanjiu breathed and closed it; She looked at the dark shadow of the mound in front of her and shouted, "as a copy, did you just move around here recently? I'm afraid you're different from before. Have you changed or evolved? Come out and let's see what you've become!"

When her voice fell, the mound rumbled and broke; In the slight vibration of the earth, a dark figure slowly straightened up from among the clods and stood under the night sky.
