There are many faint marks on the wall where the bed leans against, and the same thing is engraved... Four parallel vertical lines, plus a diagonal line drawn on these four lines.

This is usually a mark used by the detained person to calculate the day. If it were a Chinese, the character "其" might be engraved, but the wall in front of him was painted with four vertical and one oblique marks.

"Well... there are no less than six people who have carved marks on the wall..." Feng Bujue's eyes wandered on the traces and said.

It is not difficult to draw this conclusion. Although it is just a thread, the depth, length and angle of each person's engraving are different. Moreover, in order to prevent confusion with the marks engraved by others, the marks engraved by each person are separated from the marks of others.

"If you want to leave marks on such a stone wall, you can't do it with your nails. You have to have tools." Feng Bujue knelt on the bed, approached the wall, and touched and felt the traces with his palms: "These people use the same thing..." He looked around the room again: "And that thing is not in this room at this moment..." An answer appeared in his mind in a second: "Is it tableware..."

He carefully scanned the four walls, ceiling and floor of the entire room, "Well... all the marks were on this wall next to the bed, and there was no one else in the other..."

"Suppose they can only get tableware when eating, and after eating, they must return the tableware and plates together, otherwise they will be punished in some way." Feng Bujue analyzed: "Then, the time for carving these marks is their meal time..." He turned his attention to the marks: "Because I was sitting on the bed and eating, did I carve it next to me after eating..."

"No!" Feng Bujue immediately denied this speculation.

He quickly came to the iron door, and first looked out through the iron window above. The corridor outside the door was covered with wooden floors, and stone walls on both sides. The height of the ceiling was slightly higher than that in the room. At the corner between the wall and the ceiling, a fluorescent tube was installed every other section. Looking out from the cell, there was nothing worth noting in the visual range, and the place twenty meters away was dark and difficult to tell.

After a few seconds of rough look, Feng Bujue immediately lay down on the ground to observe the rectangular opening under the iron gate. He almost pressed his face on, sniffed the smell with his nose, and finally touched the edge of the opening with his hand, licked his fingers... before he stood up with satisfaction.

"The upper and lower edges of the food delivery mouth have been touched, which means that someone is indeed using this hole to convey food in." His eyes turned to the corner of the house farthest from him, "and the excretion bucket is placed on the corner of the other side of the room..." He returned to the bed and thought, "The prisoner's range of movement clearly covers the entire room... You can go to the door to get food, and you can go to the corner of the house on the other side. If these marks are carved with tableware, they can be carved on any wall."

"Then...assuming there is no such thing as tableware..." Feng Bujue stood up again, stood in the middle of the room, and put out Kudo Shinichi's signature move, holding his elbow with one hand and holding his chin with the other.

He looked at the door, his eyes as if a fragment of the past was reappearing. In the picture he was imagining, there was only a loaf of bread and a plastic plate containing soup.

"Well... it should be that there is no tableware that is more likely to be greater." Feng Bujue turned his gaze to the marks on the wall again: "Okay, then what are these used to be carved? And they must be carved on this wall..."

If you rule out wrong assumptions, the answer is right in front of you.

A flash of inspiration appeared in his mind, and a smile appeared on the corner of Feng Buju's mouth. He stepped forward, lifted the bed sheet (note: the bed sheet and the mattress on this bed are the same thing), and saw what he was looking for.

This bed is a whole, and no part can be separated. The four legs are welded to the ground. The bed bracket is completely made of iron, and the bed board is not a wooden board, but a metal spring wrapped around it.

However, among these springs, there are several broken ones. Although these metal springs cannot be completely pulled away from the bed, they can be pulled at the broken end and bent to the wall to engrave marks.

"No wonder the marks are all on the wall beside the bed, and they are all below a certain height. Due to the pulling force at the other end of the spring strip, they cannot write stably, so they can only barely carve straight lines." Feng Bujue took five minutes to guess the origin of the marks. For him, this process of observing the environment, collecting information, reasoning and solving problems was simply endless pleasure... and made him forget the faint pain in his body.

"This room has no windows, and it is impossible to see the sunrise and set. People who are locked up here have to judge how many days have passed... They must rely on feelings, biological clocks, and prove the number of times people outside deliver food to themselves." Feng Bujue paced back and forth: "And the tools for marking are not easy to find..." He thoughtfully: "Well... it seems that there are far more than six people in this room. But among the many prisoners, there are only six or seven, with calm minds and clear ideas, and have not given up on survival."

"The marks stop at the ninth road, which means that these people have been here for no more than ten days. When they see the traces carved by their predecessors, they should be able to infer... What will definitely happen on the tenth day, or the ninth night. Judging from the current atmosphere, the 1% probability is to be released, the 1% probability is to change rooms, and the remaining 98% are to be killed..." Feng Bujue snorted coldly: "Hmph... Even so, all they can do is just record the number of days they were imprisoned on the wall."

He walked to the wall and leaned against his height. "Without the plot, you can't tell whether I'm playing crazy or someone else... Well... the height seems to be about the same." He put his hand parallel to the top of his head, leaned against the wall, and then looked at it. It should be about 1.8 meters. "The costume is my own, the luggage bar..." He then looked at the game menu, the flashlight in the luggage bar, scp500, Miss moxxi's bad temper, and survival value supplements all turned gray, and they were unable to take it out. "Tsk... Sure enough." He said unhappily.

"Okay... Let me think about it... the guy who was dragging 'me' in the opening cg was obviously less than 1.7 meters, but he could drag an adult of 1.8 meters with one hand." Feng Bujue speculated on the boss's strength: "It must be more than the combat power of ordinary people...at least in terms of strength, it is similar to that of me, a level 27 player. If that guy controls the food of these prisoners and allows them to eat only one meal a day, then he can completely suppress all the prisoners here without using weapons."

Feng Bujue walked to the door: "What kind of person would this imprisonment play come from... murderer, sadist, cannibalistic, mad scientist..." Combined with the few dialogues that the boss had at the beginning, Feng Bujue knocked his fist on his palm: "Well, scientist."

"Are he talking to me? Or is he talking to himself?" Feng Bujuennian said: "Or, whether he was talking to me or talking to himself?"

While speaking, he grabbed the iron fence of the small window above the iron door and tried to pull and push it a few times. The door just made a clanging sound, and the door was obviously locked.

There are no door handles on both sides of the iron door. There is only a key hole, because there is a small window upwards, so you can pull the door without a handle.

Feng Bujue squatted down again and looked into the keyhole. It was naturally meaningless...

"Escape from the room...haha..." Feng Bujue confirmed the content of the task in the taskbar again: "Since it is a script for the advanced game period and a single-player nightmare, it must be tailor-made for me... I don't need to consider using brute force to break through the iron gate and other things. So, I just want to find a way to unlock the lock..."

He took out the pipe pliers and started a carpet-style search. Starting from next to the door, he gently tapped the walls and the ground inch by inch, trying to find out if there was any mechanism or mezzanine. He didn't let go of the corner of the wall behind the small wooden cabinet and plastic bucket. He moved the two items apart and carefully checked them.

As a result, nothing was found...

So he began to tear the sheets. The sheets were quite thick. But they were stuffed with not rotten cotton or goose feathers, but strips of cloth. They looked like some old clothes were cut and produced, with various colors and materials.

Feng Bujue found nothing but the rags from the bed sheets, so... he put all the rags on the ground and tried to sort them...

He sorted differently according to color, material, and even area, but the results were meaningless. It seemed that there was no rule between these rags. However, he still did not give up and tried to use these rags with mixed colors to complete a puzzle...

After sitting on the ground and playing for half an hour, Feng Bujue finally gave up. After a try that normal people could not make, he came to the conclusion that a normal person would make in a few seconds: this is just a bunch of useless rags.

"Oh... I'm wasting my life, a pile of garbage. Even if I braid these rags into ropes, there is no place to hang in the house." Feng Bujue said self-deprecatingly: "Where else can you hide the key?" He looked at the small wooden cabinet first: "The three drawers of this cabinet are empty." He looked at the blue plastic bucket again: "That bucket... there is nearly three inches of thick shit and urine at the bottom, and there is a possibility of hiding the key..." He swallowed: "The bottom of the bucket is too deep, and it is very inconvenient to bend over and crawl in to find it. But if I pour out the things in the bucket, I find nothing, this place..."

He wanted to drive out his strange thoughts from his mind, but he came to the small wooden cabinet first. This time he simply pulled out all three drawers from the cabinet and placed them on the ground. Then he placed the small wooden cabinet horizontally, reached in and touched and explored. Unfortunately, he didn't touch anything except dust. He pounded it carefully, but he didn't find any settings such as a secret box.

The three drawers are now placed side by side on the ground, and the wooden board is just a little thick. Without checking, you will know that there is no interlayer. The puzzle solving is once again in a dead end.

"Is it really hidden in the shit... It's too much..." Feng Bujue turned his head and looked at the plastic bucket in the corner of the room deeply, "What kind of script is this? It's too much..."

He suddenly had another idea: "Hey! I poured the things in the bucket into three drawers, so won't it be all over the floor... The drawers are shallow and easy to find."

Thinking of this, he was really ready to do it. He immediately stood up, carried a drawer and walked towards the plastic bucket. Fortunately, at this moment, his gaze swept something.

"Oh!" Feng Bujue picked up the drawer and looked at the bottom of the drawer, "Hahahahahaha!" After laughing wildly, he turned the other two drawers over and looked upwards.

It turns out that the bottom of these three drawers is written in blood. The seal is arranged according to the up and down position when they are inserted in the wooden cabinet. The information obtained is: the back of the uppermost drawer is "bed", the middle drawer is "key", and the bottom drawer is "bracket".

"The key is hidden..." Feng Bujue suddenly turned around and looked at the bed again. He walked over and knocked with a tube pliers, and soon discovered something was wrong.

On the outside of the bed, the horizontal bracket that was parallel to the bed board was hollow. The one against the wall was solid. Feng Bukyu started from one end of the bed, from the bottom to the top, and knocked on the bracket inch by inch. Finally, when he hit the middle, he heard movement inside.

"I actually hid the key in such a place... Did you find it for people?" Feng Bujue cursed.

Actually, he had nothing to complain about. Didn’t there be a prompt on the back of the drawer? It was originally a prompt to confirm the location, otherwise who would know that it was in such a place...

Pongpong, knocking and twisting. The iron bed doesn't even have a depression.

"What does it mean?" Feng Bujue said: "The excellent pipe pliers are not damaged at all when they hit it. Could it be that they want to hint me...there is a chainsaw hidden in that dung bucket?"

He sat cross-legged on the ground, finished cosplaying Shinichi Kudo, and now he started to learn to hold back his ideas...

"I have it!" Feng Bujue really had an idea.

He had the mentality of not getting pregnant even if he tried it. He used the bed once [not so hasty repairs], but he didn't expect to catch up with the failure of the skill... With the 60% success rate of the D-level equipment specialization level and the [Ice Refiner's persistence], the increase in the success rate of all active skills increased by 10%...

This made Feng Bujue begin to doubt whether his thoughts were wrong.

However, the 200 physical fitness value was in vain. He couldn't let him back down. Anyway, this skill did not have cd, so he used it again. This time, the skill was successfully used. The appearance of the bed changed.

"Sure enough! This is considered a mechanical creation!" Feng Bujue was overjoyed. Although this bed made of pure metal and cannot be separated, it seems to have a simple and clear structure, but it is also reasonable to be classified as a mechanical creation, because there is only one mechanism on it.

Just like the communication equipment that Feng Bujue repaired in Shenyou Village, this bed is also an object that cannot be observed from the game menu but can be repaired. After Feng Bujue used his skills to restore it to the [normal] quality, all the rust on the bed disappeared, and the springs that were partially broken and raised on the bed board were restored to the position.

The most critical change is to rely on the two ends of the bracket on the outside, that is, the iron bar connecting the two junction points between the head of the bed and the end of the bed. There are two additional metal wedges. Originally, these two parts have been rusted and smoothed, and the outline is not visible at all. But at this time, as long as the seal is lifted separately with pipe pliers, it can be activated.

Then, he worked hard for a few minutes and successfully removed the metal bracket from the bed.

After leaving the bed, the bracket became a hollow iron rod two meters long. Any boy who holds similar things will have the urge to imitate a monkey when he is holding a similar thing. For some reason, this passion still does not disappear after he has grown up. I wonder if it will disappear when I am worse than middle age...

Back to the point, Feng Bujue raised the hollow bracket and slapped it on the ground twice. He thought the key would fall down the hollow tube, but he took the stick and nothing fell out.

"Ah, drink..." Feng Bujue picked up the iron stick, closed one eye, and looked in with the other eye. He could see some light coming through from the other end. There was indeed a very small outline of the middle part of the stick, which should be the key, but for some reason, this thing just didn't fall out.

Feng Bujue tried to turn the stick over again to see if there would be any reaction from the other end, but the result was still the same and could not fall out. He was so angry that he sat on the ground, holding the stick horizontally, and knocked it with a pinch of the tube for a while... and when he picked it up, the position of the key still had not changed.

"What's the setting... It will move when hitting through the pipe, which means it is not fixed or welded to the inner wall, but the pipe is upright but cannot be poured out..." He repeatedly confirmed that the metal bracket was not as narrow as the two ends and wide as the middle. "It's the first puzzle. Is it necessary to get this level... What else do you want me?"

This sentence of "What else do you want me to do" suddenly inspired Feng Bujue.

"Wait, can't..." he thought, and reached into his top pocket. The previous soap, candle and numbers were randomly contained in it.

"So far, let alone the reasoning part... In actual actions, my skills [not so hasty repairs] and equipment [Mario's pipe pliers] are both necessary. Without these two things, it is impossible to reach this point." Feng Bujue said: "Since the system is a script designed to stump me, then..."

At this time, he took out the [Anti-gravity Catapator] from his bag. This item did not turn gray, so...

Feng Bujue pressed the grab button of the catapult to let the candle float, and then adjusted the candle to a suitable angle with his hands. Then, he stuffed one end of the candle into one end of the hollow bracket, and indeed... it was tightly fitted and could be embedded in it.

"Okay, this kind of puzzle design also has certain benefits. At least when I solve it, I can easily know that I am right..." Feng Bujue said, pressing the launch button.
Chapter completed!
