Police Detective

"The wall is a little sticky." Xinqiao's voice changed a little, and she was a little scared. The things she touched gave her a very uncomfortable feeling.

Bai Song protected her with one hand and held an iron door with the other hand, protecting her tightly, but she had to be responsible for finding clues from the wall.

She had picked up some clues such as number bumps, but obviously not enough.

However, as she walked forward, she touched some sticky substances, and there was also a faint smell of blood.

"Let me give it a try." Bai Song followed Xinqiao's hand and touched it, wiped a little off, put it next to his nose and smelled it carefully: "It's not blood, this is non-crystallized honey, edible. But we can't see it. If you can see it, it should still be red, usually using carmine pigment. As for the taste, the smell of blood in the blood actually comes from the divalent iron in hemoglobin, and almost all of them contain divalent iron ions. The substances all have a smell close to the smell of blood, and I don’t know exactly what they are used for.”

"Okay, I understand." Xinqiao found that he was not afraid at all.

Fear comes from the unknown, and you will naturally no longer be afraid of the known things. This kind of non-crystalline honey, since you know it is honey, there is nothing to be afraid of. Soon, Xinqiao got a clue.

S.

In the English alphabet, S means south. Since this side is south, other directions will naturally come out.

"Keep your body direction unchanged, retreat to the entrance door, and then walk east." Bai Song directed.

"Okay." Xin Qiao and Bai Song did not change the direction of their bodies at all and walked back sideways.

We took 17 steps in total when we came here. It is not difficult to follow this path when we go back.

After taking a few steps back, Bai Song found something furry touching him.

If you are afraid, if you move twice at this time, the direction will be completely messed up.

"Did anyone touch you?" Bai Song asked with concern, "Don't be afraid."

Before coming to this house, I was introduced that all the "ghosts" here are female. This is also to prevent female players from being touched by dirty hands, but Bai Song is a little awkward. He doesn't like to be touched by female ghosts either.

Fortunately, the places touched were arms, ankles, etc., which was still acceptable.

The gloomy and terrifying atmosphere in the room had a great impact on Xinqiao. With several layers of protection from Bai Song, she should still be afraid, and her figure had already lost its direction.

Bai Song counted his steps, followed the way he came, and found the entrance door.

After confirming the south, the east turned 90 degrees counterclockwise in the south direction, and the white pine walked directly to the east.

This is the difficulty with this kind of room. The exit door may not be right by the wall, but may be somewhere in the room.

Bai Song was walking when suddenly two ghosts came to seize his door.

This should be a new instruction from the background. The people backstage thought that Bai Song would put down the iron gate carrying dozens of kilograms soon. After all, this thing has pros and cons, but this man has great endurance and does not feel tired at all.

The two ghosts pulled Bai Song's door. If Bai Song didn't let go, it would be easy to lose his way. But Bai Song didn't let go. He just pulled the door over and raised it above his head.

With his height of 1.87 meters, no one could reach him when he raised it above his head. The disciples sighed, and they couldn't actually see the door at all.

After walking eight or nine steps, I came across a pillar and looked for clues on the pillar. It was a ladder. You could climb up through the ladder.

At this moment, Bai Song felt no joy and was a little confused.

Originally, when he saw the ladder, he must have climbed up and left the house. The door was big and inconvenient, so he had to give up. So why did he arrange for someone to seize the door backstage?

Is it possible that this prop can cause bugs in the next level?

Thinking of this, Bai Song was not afraid of trouble and started to climb the ladder while carrying the door.

The space here is quite spacious. Bai Song easily found the exit of the roof, opened the exit passage, and there was light.

The third room is a sound-proof room. No one is allowed to speak or open one's mouth in this room.

After arriving at this house, Bai Song discovered that the number Xin Qiao had just obtained from the wall was useful. Not only that, there were also a large number of numbers on the wall, and the whole thing was a digital wall.

The key to open the room is in the number, because it is a combination lock.

Xinqiao wiped her hands on Bai Song's clothes, saying that she was powerless with things like numbers and waited for Bai Song to unlock the password.

There were many clues here, which made Bai Song sigh. In fact, he should have brought Wang Huadong here.

If you bring Wang Huadong and Sun Jie to this place, you can clear it in minutes! Huadong himself is an expert in on-site investigation, and Sun Jie's investigation skills are also good, and neither of them needs the protection of white pine, let alone being afraid of ghosts. Especially Sun Jie, he is more familiar with seeing dead people than living people.

Pooh! Bai Song scolded himself, "The real straight man thinks that this is just for fun with female votes, not for real challenges."

After getting rid of his crazy thoughts, Bai Song began to look for clues seriously.

There are six digits in the code lock. The first one has the simplest prompt, "5358979323". Bai Song took a look and knew the answer was 3.

The next five characters are more difficult. There are a lot of garbled numbers on the wall, and many clues need to be found in drawers and other places.

Bai Song's goal is to find the four-digit password, and the remaining two can be touched. When there are only two unknown password locks, there are only 100 solutions. Press and hold the other codes to quickly turn them. It only takes one minute to complete 100 attempts.

This level is not difficult. What is difficult is how two or three people communicate and how they reach a consensus. Because speaking is prohibited, communication errors are likely to occur, which in turn makes it more difficult. In fact, the best way to solve this level is to let the person with the highest level of mathematics solve the problem, and the others can just listen to the arrangements. The more discussions there are, the more likely it is that problems will arise.

In less than ten minutes, Bai Song solved the three numbers and then started trying to find the answer. With good luck, he opened it in 30 seconds.

The first three levels take about 35 minutes in total!

There's a big explosion outside!

Who said this man was brave and foolhardy!

Not only that, anyone with a discerning eye can see that this iron gate is useful in the last level! This is actually a prop. A hidden version.

There are more and more people watching. Everyone has played similar secret rooms, such as the second level. How can they not be afraid at all? People outside can't hear the sounds inside. How can they not be afraid of the smell of blood, the pure darkness, and the sticky feeling of blood?

Even the person in charge came over to see how the man and woman passed the final test.

Just after leaving the third level, Xinqiao asked: "How do you determine that the first string of numbers is 3?"

"Ah?" Bai Song didn't expect to ask this question, "Aren't those the 8th to 17th digits of pi? Since this represents pi, pi is approximately equal to 3."

"Who has nothing to do to carry this?" Xinqiao was speechless.

There are six passwords here. In fact, theoretically speaking, if you can calculate three, it is possible to come out. If you are fast, you can complete 1,000 arrangements in ten minutes. If you are lucky, you can complete it within two to three hundred times.

After going through these levels, Zhao Xinqiao has a new understanding of her boyfriend. This is not only not being afraid of danger, but also being able to find ways to solve problems most efficiently under any circumstances. This is really a very good skill.

When many people encounter something, the first thing they do is blame others, or get extremely angry, quarrel, etc., but this is of no use. When a truly mature person encounters any problem, no matter how serious and desperate, the first thing to do is to think about how to solve it.

The fourth level is reasoning escape mode.

Seeing this pattern, Bai Song smiled.

There are three paths in this level. Since only two people are participating, you only need to pass two paths.

Each road has 4 by 16 squares, and there is a question in every two rows. To pass the level, you must answer at least eight questions correctly, but Bai Song can see that the iron gate can be pressed on the squares, and at least 5 rows can be skipped forward.

The iron gate is placed on Xinqiao's side, and Xinqiao only needs to answer five questions correctly.

Bai Song's first question: "If yesterday was tomorrow, then today is Friday." Excuse me, what day is today in the sentence?

On Wednesday, sub-questions will be sent.

Question two.

Bai Song and Xin Qiao were discussing and working on the questions.

Bai Song gradually discovered that the difficulty of the questions began to change and exceeded the outline.

A good logic question can actually be done by anyone. It does not require any additional knowledge and the test is logic.

However, the following questions gradually required professional knowledge, such as chemistry and physics, which made Bai Song frown frequently.

There is no way to jump over this place.

The iron gate can only be placed in the first position, otherwise it will definitely be overweight when holding it - there is also a pressure sensor here.

"There is a problem. We are not going to let us pass." Bai Song said: "My sixth question here is reasoning about Maxwell's equations. Can this also be called reasoning?"

"Who is Maxwell?" Xinqiao asked.

"One of the top five physicists in history, a genius who uses mathematics to deduce physics," Bai Song said: "I know how to generate a magnetic field from a changing electric field. This can also be regarded as a reasoning question. I am really convinced."

Bai Song encountered the last question here, which required knowledge of biology, and neither he nor Xin Qiao knew it.

"This is wrong. Although we are fast, we should not have these problems." Bai Song realized that something was wrong: "If it is this kind of breakthrough, it is meaningless."

"Indeed." Xinqiao also came to the last question, which was about the field of architecture.

This is not a challenge show, this is an escape room, as long as you can escape within the rules.

Bai Song immediately gave up on the question and began to check the surrounding situation. After searching, he found that when he lowered his head and walked to the fifth grid, there was already a pole above his head, and he could climb through the pole for a short section of the road ahead.

Bai Song reached for the pole, and the pressure line under his feet immediately began to drop.

Originally, Bai Song was 88/92, which meant he weighed 88 kilograms and had an upper limit of pressure of 92 kilograms. Now the upper limit of pressure began to drop, which forced him to transfer his weight to the pole.

Soon, the upper limit of pressure reached 0, and Bai Song hung on the pole.

At this time, the pole began to move, probably because Bai Song had already answered the last question. The distance the pole moved backward was only more than one meter. You only need to climb forward less than two meters with both hands to pass the level.

What Bai Song didn't know was that if he answered too few questions, the pole would have a very steep slope and would vibrate, and even an expert climber might not be able to get over it.

Don't know why.

All in all, the two of them completed the game in 46 minutes.

"Is ours too simple?" Bai Song was a little confused. He had memorized several sets of numbers to no avail.

"This is actually not simple anymore." The staff was speechless. Why is it so simple?

At this moment, a man in casual clothes came over and shook Bai Song's hand: "Hello, I am the boss here. Congratulations on breaking the record. I have an immature idea."

Bai Song broke the record very easily, and the boss discovered a new business opportunity. The original rule was that the new record should be maintained for a month before he could design a new level. Now that he saw Bai Song, he ran over immediately.

How to design a more difficult and valuable secret room while complying with regulations is actually very difficult.

This kind of secret room can often attract challenges from masters, which is definitely very attractive to this secret room city. Not only that, there are secret room competitions in the Magic City every year, and there are even world-wide competitions. Talents like Bai Song cannot be let go.

"Let me design a new level?" Bai Song thought for a moment and agreed temporarily. He was promised a lot of benefits.

Bai Song left through the safety exit at the back and had no intention of meeting those people outside. Not only was he exempted, but he also received two beautiful figures.

"The staff member just said that this figure is worth two to three thousand yuan, which is much more expensive than the original prize." Bai Song looked at it and saw that it was a character from a Japanese animation: "Why is this thing?" So expensive? Isn’t this just plastic?”

"It looks pretty." Xinqiao liked it quite a bit.

"As long as you like it, I'll give it to you too." Bai Song handed it to Xin Qiao: "Let's go and watch a movie."

"Okay. I'll leave it there for you to hold first. I can't fit it in my bag."

The subway in Beijing usually operates until around 11:30, but the city has a very rich nightlife, and people are still everywhere at three or four in the morning. The two took the subway and returned to the cinema where they went in the afternoon.

"Are you tired? If you are, your ticket will be refunded. Just go and have a rest. This place is also close to your school." Bai Song said.

"I'm fine. Let's go and see it once it's decided." Xinqiao said that he had no class tomorrow.

The two of them got off the subway and were about to leave the subway station. Bai Song crossed the valuable figures in his hands while walking. As they walked, Bai Song suddenly saw a familiar figure.

The Chinese New Year is approaching, and the temperature in Beijing at this time is already around minus ten degrees. This is already the last subway train. The staff in the subway are driving away the vendors near the subway entrance. Bai Song suddenly sees the little boy he saw in the movie theater this afternoon. .

In the child's hand, he was holding a frozen, hard steamed bun.
