Water Level Rises! Bu Wang's Problem-Solving Ideas! Lin Yu Feels Confused!

Lin Yu was momentarily lost in thought upon hearing the Crowman's question.

This was a very typical "pool filling" problem, a topic that belonged to elementary school mathematics.

As expected, Number Eight, who was the "student" in this scenario, wiped the water droplets from his face and spoke up after hearing the question.

"A pool filling problem, that's easy. All you need to do is assume time is X!"

He said somewhat eagerly.

Lin Yu shook his head.

No, the difficulty of this problem wasn't in the math itself.

Before he could speak, his girlfriend, the "doctor" with the ID "April," spoke up with a helpless sigh, "But do you know the volume of this room, the inflow rate, and the outflow rate?"

Number Eight was taken aback. "Huh? Yeah... Examiner, what are the numbers for these? Can't you give us a hint? This should be part of the hints, right!"

He looked at the Crowman expectantly and asked.

The Crowman's feathers and the hood on his head were also wet from the water, making him look drenched.

He looked at Number Eight and said, "Caw caw, that's not within the scope of 'hints'."

Uncle Tie looked at Number Eight and shook his head.

"What you're asking is probably the crux of the problem – a math problem with elementary school difficulty, how could it appear in a death game... This is testing our estimation skills."

With that, Uncle Tie walked to the edge of the room and started wading through the water, circling the room.

Number Eight and April looked at each other, puzzled. "What is this uncle suddenly doing?"

Before Lin Yu could speak, the young thief named "Bu Wang" chimed in, "I think he's measuring the length and width of this room using his 'stride'... This uncle is wearing a safety helmet and his profession is 'Craftsman,' so he should be good at this kind of thing."

Bu Wang spoke, and Lin Yu nodded slightly.

However, while Uncle Tie was measuring the room's dimensions, Lin Yu wasn't idle. He walked towards the Crowman.

"Excuse me, should the final answer be precise to the minute or the second? That should be within the scope of hints, right?"

Lin Yu asked with a smile.

The Crowman glanced at Lin Yu, shook the water off his body, and replied.

"Caw caw, let me think... How about this, just keep the error in my answer within five minutes."

The Crowman said, and everyone breathed a sigh of relief.

The error needed to be within five minutes!

This meant that the estimation didn't need to be particularly accurate.

Soon, Uncle Tie finished his circuit and returned to the group.

"Based on my estimation, the length of this room should be around 9 meters, and the width around 6 meters... The height..."

Uncle Tie stretched his hand towards the ceiling. "Combined with these dimensions, the height should be around 3 meters."

Number Eight quickly interjected, "Then I know! The 'volume' of this classroom should be around 162 cubic meters."

He said, then quickly added, "Next, we just need to know the inflow and outflow rates to calculate it!"

As Number Eight spoke, Uncle Tie and April nodded, seemingly starting to ponder how to measure the inflow and outflow rates.

"If the speed of each water outlet is uniform, we can find a container to catch all the water from a single outlet. Then, by timing how long it takes to fill the container, we can calculate the rate per unit of time for each outlet. And there are ten outlets here..."

April was the first to suggest a method.

But her words were interrupted by Bu Wang.

"There's no need for that. Even though a five-minute error is allowed, the more data you estimate, the larger the final error will be..."

Bu Wang looked at Uncle Tie and asked, "Uncle, I have just one question... Are you sure the height of this room is 3 meters? Can the error be controlled within 10 centimeters?"

Uncle Tie nodded. "Although measuring the height isn't as easy, based on my experience, this proportion is about right for three meters! I've been working construction for so many years, my eyes are my ruler!"

He said with some confidence.

Bu Wang took out a utility knife from her pocket.

"This utility knife of mine is a standard 15 centimeters long," Bu Wang said as she walked to the corner of the room, placed it against the wall, with the tip touching the water surface and the body locked against the corner. "Then, we only need to calculate the time it takes for the water to completely submerge this utility knife... and then multiply that by 20 to get the approximate time needed."

Bu Wang said, and then began timing herself.

"One, two, three..."

At this moment, Uncle Tie also had an idea.

"Converting this problem into the speed of water level rise, that's a great idea... I have a 'pocket watch' here, it's an item I obtained. Let's use this to time it!"

He also walked to the wall, took out his pocket watch, and started timing.

April and Number Eight also understood Bu Wang's intention, and both showed expressions of admiration.

"I see, just like this... we can estimate a relatively accurate time," April murmured. "I really overlooked this."

Number Eight pouted. "I thought it was a math problem, but it turned out to be like a riddle, letting this 'Thief' steal the spotlight."

Hearing her boyfriend's slightly sour words, April nudged him in the back. "Watch what you say. Don't always be so prideful and talk nonsense!"

April's tone was a little displeased.

Upon hearing his girlfriend's words, Number Eight could only awkwardly rub his nose and crouch down.

"If our eyes are level, it might be more accurate. I'll help watch when the water stops rising."

Watching the group huddled by the corner, observing the rising water level, Lin Yu felt something was off.

Just as "Uncle Tie" had said at the beginning, a simple elementary school math problem shouldn't appear in the Death game.

At first, everyone thought the difficulty of the problem lay in "estimating various data."

But after Bu Wang simplified all the data into the simple metric of "water level," coupled with the "five-minute" margin of error allowed by the Crowman...

This problem was far too simple!

But, what if they considered it from a different angle?

Just as Number Eight had said earlier, what if this wasn't a logic or math problem, but a "riddle"?

The biggest characteristic of a riddle is that the question contains a "trap."

Moreover, the Crowman before them was clearly not an NPC mechanically reciting rules and questions, but a being with high intelligence and independent consciousness.

It would be able to "judge" which of its questions and Number Eight's questions it could answer.

However...

It was precisely because of its previous answer that Lin Yu felt its tone was a little off.

"Let me think," "Then," "That's fine" -- it used three uncertain and imprecise tones for a "hint," or even for words related to "answering rules."

The Crowman didn't seem to care much about the "margin of error" for the answer; it just casually threw out five minutes!

Rather, it was the fact that the Crowman hadn't mentioned any "margin of error" from the start that Lin Yu found strange.

With this thought, Lin Yu walked towards the Crowman again.
