Infinite Survival: The winner takes all!

Immediately afterwards, the black display suddenly lit up, and a three-color countdown bar appeared at the top. The bar was green for 5 minutes, yellow for five to eight minutes, and red for eight to ten minutes.

There are also lines of small characters in the middle of the screen.

‘The room will be in flames in 10 minutes, please open the door and leave as soon as possible. ’

‘The three door numbers can only be opened if they are posted in the correct positions. ’

‘You can only change each door number once. ’

'The door passwords of the light bulb control room are all passwords, which will become invalid immediately after being used once. ’

'Happy gaming! '

Li Ming looked at the rules on the screen and pondered for a moment. Then he walked quickly to the door and pushed hard. The door did not move at all, indicating that the number currently arranged was wrong.

The light bulb above the door was a very ordinary and old-fashioned tungsten lamp. He reached out and touched it, but found nothing unusual.

After looking around, I couldn't find any useful information in the room. It seemed that I had to go to the light bulb control room.

He came to the control room door thoughtfully and quickly pressed the code lock without hesitation.

Ding, there was a crisp sound, and the red light on the metal door turned green.

After Li Ming pushed it open, he found that there was another similar metal door inside.

When he came to the second door, he entered the same password again. The red light instantly turned to green, but the door could not be opened.

He was stunned for a moment, then as if he thought of something, he turned around and closed the first door, and then pushed the second door. Sure enough, this time it was pushed open easily.

The control room is extremely simple, with only three up and down switch buttons. Each switch corresponds to a number, from left to right they are 1, 2, and 3.

Seeing this, Li Ming already understood that he needed to match the number on the console with the door number under the light bulb outside.

If he presses the switch No. [-], but the light on the door No. [-] turns on, then he has to remove the No. [-] door number and put the No. [-] door number up.

Press switch No. [-] again to see which door light is on, and you can determine all house numbers.

This level seems very simple, but there are two problems. First, the control room is sealed. Even if he presses the switch, he doesn't know which light is on.

Second, he can only enter the control room once. He needs a password to enter from the outside. Now the password has expired, and the setting that the two doors cannot be opened at the same time also eliminates any possibility of opportunism.

"First of all, you can't press three switches at the same time, because this doesn't provide any information, so you can only press one or two."

"If you press a switch, you can only verify one door number, and the other two numbers cannot be determined."

"In the same way, if you press two switches, you get the same information as pressing one switch."

"It is known that the numbers 1, 2, and 3 from left to right outside are wrong, then..."

"Uh, no, this information seems to have no meaning, because as long as one number is wrong, the door cannot be opened. Therefore, even if he changes the door number to a correct one, there is no way to determine the untouched door number. It must be wrong, if you can’t be sure, then you can only take a 50% chance.”

"It's definitely not right." Li Ming scratched his hair and laughed at himself: "If that's the case, then why is it called the Hall of Wisdom? Let's just call it the European Emperor's Hall."

Time passed little by little, and 2 minutes passed in the blink of an eye.

Li Ming frowned and was still thinking hard. He thought he was pretty good at mathematics, but when faced with this seemingly simple problem, he couldn't find any solution.

well? A flash of lightning suddenly flashed through his mind, mathematics? Why do I have to use math to solve puzzles?

Realizing he had hit a dead end, he tried to think outside the box and think about the lightbulb switch problem from other angles.

Hey, tungsten light? Yeah, why tungsten? Li Ming was startled for a moment, then burst into laughter.

"It turns out that mathematics cannot solve the light bulb problem, but it can find the answer from common sense in life."

He smiled and shook his head, flipped the light switch No. [-], and then stayed there silently counting the time.

After about 2 minutes, he turned off the No. [-] light, pressed the No. [-] light switch, and then quickly left the control room.

Li Ming glanced at the time bar on the screen and saw that 4 minutes and 22 seconds had passed.

"Fortunately, it's less than 5 minutes." He breathed a sigh of relief.

Since the game sets different time periods, it must be meaningful. The most reasonable guess is that the shorter the clearance time, the richer the rewards.

He turned his head and glanced at the light on the door, and found that it was door No. [-] that was on, and that he pressed switch No. [-] when he left the control room.

So, he took off the door numbers No. [-] and [-], and then put the door number No. [-] on the door of the original room No. [-]. Then, Li Ming touched the light bulb on the middle door with his hand. It was cold.

To make sure he was not mistaken, he touched the light bulb above the door of Room [-]. It was a little warm, indicating that it had been on.

In the control room, he only pressed the No. [-] and No. [-] light switches. Now that the No. [-] light has been determined, it means that the correct number for the door of Room [-] is No. [-].

Therefore, the correct arrangement of numbers should be 2, 3, 1.

This problem is actually very simple, because the tungsten filament lamp will generate serious heat when it lights up. You only need to let any one bulb light for 2 minutes, then turn it off, and then turn on the other bulb. You can determine the correct position of the two bulbs when you leave the control room.

Of course, if you can't think of this common sense in life, you can only bet on a 50% probability.

When the timer reached 4 minutes and 51 seconds, he affixed the last number plate.

Click!

The three doors opened automatically, revealing three passages of different colors, red, white and blue.

Li Ming waited for a few seconds, and when there was no prompt, he stepped into the nearest red channel.

Entering the passage, he looked back and found that the door at the back was gone and had become a solid wall.

Ding!

At this time, a mechanical voice suddenly sounded in his mind.

‘Congratulations to player Li Ming-27 for clearing the level within the shortest time limit. ’

‘The reward has been sent to the system, please check it carefully. ’

Li Ming quickly opened the system to see what was given in the first level.

The receiving interface gives two rewards, namely 3 survival points and a silent pistol.

The silent pistol is a bit useless, but the 3 survival point reward is pretty good. After all, this is just a small level.

"It's a bit generous." Li Ming felt a little surprised, but after thinking about it carefully, it seems to be quite normal. It doesn't matter if you pass one level, because you have to pass seven levels to return to the real world, and if you fail at any level, all your previous efforts may be wasted. Even lose your life.

Collecting his reward, he continued along the passage and soon saw a wooden door.

It opens with a light push.

Inside is a small room, the area should not exceed ten square meters.

There is a beautifully carved rectangular wooden table in the middle, with two fur seats at both ends of the wooden table.

Li Ming walked in on the purple patterned carpet. He glanced around and saw no one else. However, there were two chairs in the room. It couldn't be a single-player game.
