After pressing the button, the candle was propelled into the hollow support by the catapult's force. In that instant, a hiss came from inside the iron bar, followed by two clangs. The key really did fall out of the support.

Feng Bujue stowed the catapult and looked inside the hollow support again from one end. He found that the iron bar was now blocked in the middle; no light could pass through. This was probably because the candle was stuck in the position where the key had been.

He bent down, picked up the key from the ground, opened the menu, and looked at the item description:

[Name: Key to Cell Zero]

[Type: Story-Related]

[Quality: Common]

[Function: Disappears immediately upon use. After that, the door to Cell Zero can be freely opened or closed.]

[Can be brought out of this scenario: No]

[Note: Why isn't this item classified as a consumable? I think you know the answer.]

"The notes are getting more and more brazen," Feng Bujue said, looking at the key. "Just because the player knows, you don't have to write it? Will there be a note in the future that says 'You know,' and I have to figure it out myself?"

Muttering, Feng Bujue walked to the door. He inserted the key into the keyhole and turned it clockwise. With a click, the lock was opened, and the iron door naturally slid open a few inches into the cell. Feng Bujue took the opportunity to pull the door open.

He glanced back at the room, wanting to make sure there was nothing else he could use. Finally, his gaze settled on the hollow support. Although it should revert to its old, rusty state after the fifteen-minute skill duration, even in that state, its hardness would still be about the same as a pipe wrench, based on experimental evidence. Therefore, Feng Bujue decided to take the hollow iron bar, which was blocked in the middle by the candle.

[Name: Hollow Support]

[Type: Weapon]

[Quality: Common]

[Attack Power: Weak]

[Attribute: None]

[Special Effect: None]

[Note: An iron bar removed from a bed frame.]

Looking at the item in the game menu, there was also a qualifier box. If he focused on it for a few seconds, a text box would pop up, saying: [This item is currently under the effect of a skill; the quality will change after the time limit is reached. System prompt: Please be sure to understand the situation before trading this item.]

"Hmm... how thoughtful," Feng Bujue said, understanding the meaning of the prompt.

In a game like Thriller Paradise, there were definitely more than just one skill that could change the nature of an item. Not to mention the quality, there were probably skills that could change the item's attributes, appearance, and special effects. To prevent people from using these skills to scam others by temporarily changing an item and then selling it, the system had meticulously set up reminder text on these changeable items.

"A two-meter-long iron bar, it can definitely come in handy somewhere, like poking things, pole vaulting or something..." Feng Bujue said to himself. "Even if it's useless, it's not bad to hit people with it as a weapon. An inch long, an inch strong." That was true, but we all knew very well that the other reason this guy was carrying this stick was because he wanted to imitate a certain monkey and show off a few moves.

Feng Bujue walked out of the cell, and as he crossed the doorway, the system prompt sounded: [Current task completed, main task has been updated.]

The [Escape the Room] task in the taskbar was checked off, and the next task appeared: [Explore the 2nd floor underground, open the door to the upper level.]

"So this is the second floor underground..." Feng Bujue murmured. "Speaking of... just getting out of this starting room was already so difficult... It's just exhausting. Now, to break through a whole floor, the amount of puzzle solving..." A look of excitement appeared on his face. "This is definitely going to kill people!"

Both the tone of his voice and the expression on his face showed that this weirdo was quite happy, but what he said meant something else...

After leaving the cell, Feng Bujue brandished the stick, walking down the corridor with shouts of "Ho! Ha!" He was acting like a bear cub on a spring outing, completely without any sense of tension.

The corridor after leaving the room had no doors on either side, and the corridor was empty, with nothing but the lighting equipment above. Of course, Feng Bujue already knew this when he looked out from the room.

After about fifty meters, he saw the doors of other cells.

In front of him was an area with six cells, three on the left and three on the right. The iron doors were painted with numbers, which Cell Zero did not have. The left side was one, three, and five, and the right side was two, four, and six. Between the doors of Cell Two and Cell Four, there was also a plastic trash can less than a meter high, the kind with an opening at the top. Although he didn't know if there was anything inside, at least no strange stench came from the trash can.

Looking ahead, he could see the stairs to the upper floor not far away.

Feng Bujue didn't rush to try to open the doors, nor did he look into the rooms through the iron windows. After seeing the doors, he stopped his meaningless stick-waving and held the iron bar diagonally in his hand, keeping both ends off the ground, and tiptoed closer. As he approached the doors, he bent down and quickly slipped past.

What was in the cells was currently uncertain. Looking inside through the iron windows, or being seen by the people or things inside, might trigger some strange flag, so Feng Bujue decided to sneak past first and see what the situation was like at the stairs.

He successfully passed through the area with the six doors and arrived at the bottom of the stairs. After walking up the stone steps and back down once, Feng Bujue saw a classic black iron-barred prison door. Through the bars, he could directly see the corridor on the upper floor. The layout of the 1st floor underground was almost the same as the floor below, but the stairs leading from the 1st floor underground to the 1st floor above ground should be at the other end, above Cell Zero.

Feng Bujue stepped forward and tugged at the iron bars a few times, but it wouldn't open. At this moment, he had an idea and took out the [Endless Grenade Magazine] from his bag.

The [Endless Grenade Magazine] was a "tool" type item, but unlike tools like flashlights, the grenade magazine only generated consumables, rather than relying on the support of consumables to operate, so it was not prohibited by the system.

Feng Bujue tried to fix the grenade at the position of the lock to see if he could blow up the lock directly. As a result, he found that the grenade could not be taken out...

"The grenade magazine can be used, but the generated items inside can't be used?" Feng Bujue muttered.

He guessed correctly. Although the grenade magazine was not prohibited, the generated items inside were themselves "consumables," which were inevitably restricted by the system, preventing them from being taken out.

"Okay..." Feng Bujue shrugged and left the door.

He hadn't had much hope for this violent breakthrough method anyway... When he was at a loss in Cell Zero, he had also considered using grenades, but he quickly dismissed the idea. If he used a Mark II grenade in that small space, his 26% survival value would definitely be wiped out...

"So, the method to open this prison door and enter the 1st floor underground must be in these six cells," Feng Bujue said, walking back down the stairs and looking at the puzzle-solving area in front of him.

He came to the wall, gently put down the iron bar, and then interlaced his fingers, stretching his arms straight with his palms facing out. Then, he kept this posture and raised his hands above his head, as if warming up for some physical activity.

"Where to start..." he muttered, as he came to the door of Cell Six. He cautiously approached, keeping a step away, and moved his face to the iron window.

The light in the corridor basically illuminated the environment in the room. The layout of the cell was basically the same as Cell Zero. The bed and the plastic bucket were the same, but whether there was a small wooden cabinet could not be confirmed, because that corner was next to the door, in a blind spot.

"Hmm... no one here..." Feng Bujue didn't see anyone in the room. He tried to push the door, but it wouldn't open.

Then, he peered through the iron windows of the five doors, Five, Four, Three, Two, and One, and the situation was exactly the same.

Next, Feng Bujue came to the trash can, took out the [Eighteen Bronze Men's Folding Stool (No. 5)], sat down, and prepared to thoroughly inspect the trash can.

Feng Bujue's clothes came with gloves, and this part of the clothing was the same as the face, which could be displayed as needed. From the beginning of this scenario, Feng Bujue had been in a bare-handed state, and he was still so now.

There were bloody bandages, plastic plates with food residue, and some plastic plates with shit on them in the trash can... Obviously, after the prisoners finished eating, they developed another use for the plates.

Feng Bujue originally wanted to use his hands to rummage through it, but after he sat down and took a closer look... there was no way, he had to pour it out.

He first took the iron bar over, then dumped the contents of the trash can on the ground. Then, he sat on the folding chair, rested the iron bar on his shoulder, and used the lower end of the iron bar to poke and rummage through the garbage on the ground. After all, this thing wasn't his equipment, so it didn't matter if it got dirty.

While rummaging, Feng Bujue pondered: "Strange... every room's shit bucket has a smell, and judging from the things stuck to these plastic plates, it hasn't been long since they were used, so why is there no one in the rooms..." He paused and muttered, "Could they have been taken away at the same time not long ago?"

After rummaging for a long time, Feng Bujue only found dirty bandages and plastic plates. Only after pouring everything out did he realize that there wasn't much mush and liquid in the trash can, so it didn't smell too bad, but it still looked pretty disgusting.

Just as he was about to shift his attention, he suddenly saw something special. At least in this trash can, this item was unique.

[Name: Carved Dentures]

[Type: Story-Related]

[Quality: Common]

[Function: Unknown]

[Can be brought out of this scenario: Yes]

[Note: Some information is engraved on the inside of the teeth.]

Feng Bujue picked up the dentures and randomly grabbed a relatively clean bandage to wipe them. Then, he turned them over and examined them carefully, and sure enough, he saw a hint related to the puzzle.
