The Secret Chamber of the Card Game

After reading the plot cards of Li Mo and Cheng Mu, Xiao Lou was in a complicated mood and didn't know what to say for a while, so he asked him in his heart, and put the two plot cards back into the card bag.Yu Hanjiang didn't speak, and the personal space suddenly became extremely quiet.

After a while, A of Hearts broke the silence with a smile: "Old rules, you can rest after clearing the Hearts Secret Room. This time, the rest time for you is still 8 hours. You can take a shower and sleep now. At 8 o'clock in the morning, the alarm clock will ring on time. Wake you up, when the time comes, please go to the card wall to draw the cards for the next level, I will not accompany you. Goodbye, both of you."

Xiao Lou nodded to her: "Okay, goodbye."

The ace of hearts disappeared in front of him, Xiao Lou looked at Yu Hanjiang and said, "Captain Yu, take a break."

Although there were sleeper compartments on the train for the past few days, the two of them were thinking about the case and did not sleep well.The most benevolent Ace of Hearts among the gatekeepers prepared a simple bathroom and two single beds for them this time. Yu Hanjiang and Xiao Lou took a bath one after another and lay down on the bed.

Xiao Lou remembered the clips in the story card, and he couldn't fall asleep for a while, and Yu Hanjiang couldn't sleep either, so the two simply chatted.

Yu Hanjiang said: "The secret room of hearts and the secret room of spades are like two worlds."

Xiao Lou quickly understood what he meant: "Captain Yu meant that there are strict rules in the Chamber of Hearts. Murder is a crime, and the murderer will be arrested and sentenced... But in the Chamber of Spades, in order to pass the level, the intruders can even do whatever they want. Massacre free men?"

Yu Hanjiang nodded and said in a low voice: "Among the four gatekeepers, Heart is the most principled. Zhang Qing, the murderer in the Fenglin High School case, was finally sentenced to death, and the two murderers in the speed train case were also arrested by the police. However, in the secret room of Spades 3, free people killed challengers, and challengers massacred aborigines, no one cared about it at all, and some challengers even directly released zombie viruses in the square in order to clear the level."

Xiao Lou pondered for a moment, then said: "Perhaps, what the Ace of Hearts governs is an orderly world, where people will abide by morality and laws, and live a normal life. But what the Ace of Spades governs is like a zombie town." , the financial crisis, these are all similar to the doomsday world, in this environment, people will naturally despise the constraints of morality, law and social rules in order to survive, exposing the dark side of human nature."

Although the murder in the Hearts Chamber is bloody, the final ending will always give people hope and warmth.The world of spades is extremely gloomy, people can do whatever they can to survive, and murder does not need to be punished here, the rules of the two types of secret rooms are completely different.

Yu Hanjiang frowned and said: "From this point of view, the City of the Sun and the City of the Moon are probably also orderly worlds. The tour groups and girlfriend groups on the bullet train all depart from the City of the Sun, and the city of the Moon is still singing Yes, the free people in the two main cities should live normally."

Xiao Lou speculated: "What if the challengers find the beauty of this world after arriving in the main city, and gradually integrate into it, will they not want to go back? After getting the money, buy a big villa here? Those who can’t find a partner in reality get married and have children here? Will their will be gradually worn down, and they will lose the motivation to leave the card world?”

Yu Hanjiang nodded, and his face was a little ugly: "So, after some challengers arrive in the main city, it's not that they are incapable of continuing to break through the barriers, but that they are used to life here and don't want to take risks at all."

When the will of the challenger is worn down, the belief in "going back" in the heart becomes less strong.

Clearing the SS-level secret room is no longer important to them.

The gatekeeper said that if you want to go back, you must pass the secret room with SS difficulty.It didn't say that all challengers had to go to the highest chamber.

Xiao Lou said with a headache: "If this is the case, then I can understand why there are more than 8000 million challengers but no one has passed the level."

Yu Hanjiang was silent for a moment, and said firmly: "Don't worry, I must go back. This world, good or bad, is as unreal as a dream. Stay here and be assimilated. After a long time, maybe we will gradually lose our humanity .”

"That's right." Xiao Lou smiled slightly and said, "Don't be too pessimistic. There must be many people in the main city who are determined to go back like us. Those who can pass the fourth level are not weak. We might find some stronger partners."

"I hope so." Yu Hanjiang said in a low voice, "Let's rest first, and we will go to square pieces in the next level."

It was completely dark outside the personal space, and a sense of drowsiness struck, Xiao Lou and Yu Hanjiang quickly fell asleep.

A night without dreams.

The alarm clock at 8 o'clock in the morning wakes them up on time.

The two washed up quickly, then walked to the card wall and drew out the next card - the 4 of diamonds.

After the familiar dizziness passed, they opened their eyes again, and the two of them had come to a strange space.

It is a closed room with an area of ​​about 4 square meters. The walls and floor are covered with white marble with patterns. There is a stone table in front of it. There is a balance on the table, and there is an exquisite small wooden box beside it.

A reminder popped up in the floating box in front of the two of them at the same time——

Welcome Xiao Lou and Yu Hanjiang to enter the square piece 4 secret room [Balanced World].

Please unlock the mechanism of the secret room, find the exit, and escape from the secret room within 30 minutes.If the timeout expires, the checkpoint will fail.

The secret room does not contain hidden organs, and there is only one exit from the secret room. Good luck to both of you.

After swiping the prompt, a clock appeared above their heads at the same time.At this time, the time points to 8 o'clock in the morning, and the second hand starts to "tick" to swing. There is a red scale mark at 30:8, which means that if you cannot leave the secret room after 30:[-], you will fail to break through the level.

Secret rooms like mechanisms are what Yu Hanjiang is least good at. He glanced at the clock, followed behind Xiao Lou, and said, "Is the mechanism in this room a balance on the table?"

肖楼上前一步，打开旁边的精致木盒，果然看见了一些指甲盖大小的银色金属砝码，立方体的砝码体积一致，上面分别标有1g、2g、3g、4g、5g、6g、7g、8g的数字标志。

Xiao Lou weighed it with his hands, and the weight was indeed different.He smiled and said: "Balance the world, this mechanism is a mechanism controlled by gravity, as long as you put the weight on it and reach the specified weight, you should be able to open the door of the secret room."

He looked down at the numbers on the weights carefully, and said: "From 1 gram to 8 grams, there are a total of 8 weights. If you put 2 and 3 on one side, and 1 and 4 on the other side, the total is 5g... But I I don’t think it’s that simple, and it’s more likely that the correct solution is to put all these 8 weights on it and make the weights on both sides of the balance exactly equal.”

Although Yu Hanjiang is a physics scumbag, he still knows how to use the balance.

The balance in physics is similar to the most primitive scale. Put the object to be weighed on one side, and put weights of different weights on the other side. When the balance is in a completely horizontal position, it is proved that the weights on both sides are equal, and the weight of all weights The sum is the weight of the object.

As Professor Xiao said, since the Chamber of Secrets gave eight weights, all eight must be used.

Otherwise, it would be too simple to put 2+3 on one side and 1+4 on the other.

From 1g to 8g, how should the eight weights be placed to make the balance completely balanced?

虞寒江的脑子里开始飞快地算加法，结果他还没算完，肖楼就上前一步，认真地把2g、4g、5g、7g四个砝码摆在左边，把1g、3g、6g、8g四个砝码摆在右边。

The sum of the weights on the left side of the balance is 18 grams, and the sum of the weights on the right side is also 18 grams.

1+8、2+7、3+6、4+5，两两组合都是9g，一边放四个就是18g。或者，左边放1、2、3、5、7，右边放4、6、8，同样是18g。这道题的解法其实非常多，只要满足“天平”的两边重量相等，就可以轻松解开重力机关。

The first mechanism is so simple, obviously to let the challenger understand the principle of "balance".

After a slight shake, the balance reached a perfect balance, and the pointer pointed to the middle red scale.There was a "bang" sound in the ear, and the stone wall in front of the table opened a door in front of the two of them that was big enough for them to pass through side by side.

Xiao Lou's eyes lit up: "It's done."

Yu Hanjiang: "..."

Again, when he was reviewing the question, Professor Xiao had already written the answer.

Yu Hanjiang decided to give up thinking - anyway, he had already won once in the secret room of squares, and it would be good to continue winning today.

After leaving the first secret room, a stone wall was erected in front of the two of them, and a straight passage appeared on the left and right sides.

Xiao Lou went to the left first, and when he reached the end, he saw a secret room of about 4 square meters, with a balance on the table, but this time, the chips in the box were not weights marked in grams, but Some Chinese character cubes.

A cube of 5cm×5cm×5cm, with twelve Chinese characters written on it——

Xiang, Sha, Tian, ​​Fei, Man, Lang, Partridge, Court, Resentment, Partridge, Tao, Fang.

Yu Hanjiang felt that these words were very familiar, and they should be able to form a poem. Xiao Lou quickly realized, and said, "Twelve words, when combined, are exactly four ci-pai names."

He took these words out of the wooden box, rearranged them, and sorted out four word cards——

Concubine Xiang, Partridge, Lang Taosha, Man Tingfang.

Looking at the Ci Pai in front of him, Yu Hanjiang wondered: "What is the relationship between Ci Pai and weight? These character cubes are all the same size, so the weight should be about the same?"

Xiao Lou thought about it carefully, picked up a complicated "Partridge" character and a simple "Heaven" character, weighed them with his left and right hands respectively, and said: "The difference is very small, but the complicated characters are obviously heavier than the simple ones— —The weight of Chinese characters should be related to strokes.”

He verified the two words again, and compared "Tao" and "Tian", the former was obviously heavier than the latter.

Xiao Lou confirmed his thinking, pointed to the two word cards on the table and said, "Captain Yu, please count the strokes of these six characters, and I will count the remaining six."

Yu Hanjiang nodded, writing quickly in the palm of his hand, and said while writing: "Partridge has 16 strokes, partridge has 10 strokes, sky has 4 strokes; waves have 10 strokes, Tao has 11 strokes, and sand has 7 strokes."

Xiao Loudao: "Partridge Sky adds up to 30 paintings, Langtaosha 28 paintings, Xiangfei Resentment 27 paintings, and Man Tingfang 29 paintings. Put 30 and 27 together, 28 and 29 together, exactly 57 on the left and right sides. Draw, let's try."

The two looked at each other, and quickly placed the three blocks of partridge, partridge, and sky in the 30th picture, and the three blocks of Xiang, Concubine, and Resentment in the 27th picture on the balance on the left. The word is placed on the right scale.

Sure enough, the pointer of the balance swayed for a while, and pointed to the middle, proving that the analysis of the two was correct.

Yu Hanjiang gave Xiao Lou a thumbs up in his heart.

This question is actually not difficult. First, the messy characters are formed into word cards, and then the strokes of the word cards are analyzed. You will find a balance point - the strokes of the four word cards add up to exactly 30, 29, 28, 27, 30 and 27 combinations. The combination of 28 and 29 is completely equal on both sides.

The mechanism of square 4 is a balance. Since the theme of the secret room is "balance the world", as long as this balance is found, the mechanism can be unlocked.

……

After unlocking the mechanism in the small room on the left, the wall in front of the two did not change, but there was a "bang" sound behind them, as if the wall somewhere was turning.

Xiao Lou and Yu Hanjiang quickly turned around and returned.

When they walked halfway, they saw a stone door appearing on the wall that blocked the passage just now.But at this time, the door was closed, and Xiao Lou said as he walked, "You should unlock the mechanism in the room on the right, so that this stone door will open."

Yu Hanjiang nodded and quickly followed him.

The two walked to the end of the corridor on the right. In a small room of about 4 square meters, there was also a table with a balance on it. The box next to it was still filled with chips—but this time it was not numbers or characters. But a few strange flat figures.

Xiao Lou picked up those geometric figures, looked at them carefully, and said: "Square, rhombus, triangle... There are only two kinds of side lengths: 5cm and 10cm. Assume that the weight of a 5cm line segment is 5g, and the weight of a 10cm line segment is 10g. We only need Just make the line segments at both ends of the balance into the same amount."

Having said that, Yu Hanjiang also found it very simple, and quickly cooperated with Professor Xiao to convert the line segments of several figures.

长方形的长是10cm，宽是5cm，重量可以换算成10+5+10+5=30g。

Rhombus, square, all four sides are 5cm long, and the weight is converted to 20g.

Two equilateral triangles have three sides of 5cm and weigh 15g.

Xiao Lou placed the rectangle and square on the balance on the left, and the rhombus and two equilateral triangles on the balance on the right. The left and right sides weighed 50g, and the pointer of the balance accurately pointed to the middle.

The sound of the wall turning could be heard next to his ears, and Xiao Lou smiled and said, "It succeeded."

Yu Hanjiang continued to follow behind Xiao Lou... The feeling of lying down is really comfortable.

The two turned back to the corridor.

The stone door in the corridor was opened just now, Xiao Lou and Yu Hanjiang looked at each other, and entered the stone door one after the other.

As soon as they walked in, the stone door suddenly closed behind them.

The two were trapped in a closed chamber.

Xiao Lou quickly looked around. This room is spacious, about 20 square meters. The floor and surrounding walls are all the same white patterned marble tiles.Unlike other rooms with tables and balances, this room is empty, without any tools or mechanisms.

However, as the two entered the room, two huge round stones with a diameter of about 2 meters suddenly rose from the ground.

One of the stones is red and the other is blue, with scales similar to electronic scales.

Xiao Lou went to the side of the stone to observe carefully, Yu Hanjiang also followed, and said: "It seems that if you want to get out of this secret room, you can only rely on these two big stones. The scale on it should also be the weight?"

Xiao Lou nodded and said: "The topic of this level is called Balance the World. The three organs we encountered before were all balances. The first one puts digital chips, the second puts Chinese character squares, the third puts geometric figures, and the fourth one puts geometric figures. There is nothing in this room, do we want us to stand up by ourselves?"

Yu Hanjiang said: "Try it."

He walked over and stood on the blue stone, the pointer under his feet immediately rotated, and finally stopped at: 75kg.

Xiao Lou also turned around and stood on the red stone, the pointer under his feet was fixed on the number 65kg.

There was no response from the four walls, and the room was so quiet that a needle could be heard.

The two looked at each other and looked at each other.

Xiao Lou said helplessly: "We are not the same weight, the organ cannot be opened."

Yu Hanjiang turned around and asked, "Professor Xiao, are you only 65 kilograms? You are a bit skinny with a height of 1.8 meters. You should eat more in the future."

Xiao Lou smiled and said, "I don't get fat no matter what I eat. It's probably because of my physique." On the contrary, Yu Hanjiang is very strong, with a height of 1.8 meters and 75 kg. He is neither fat nor thin, and has muscles.

Yu Hanjiang looked at the scale at his feet, frowned and said, "I'm heavier than you, and there's nothing else in the room, or... I'll take off my clothes and put them on for you?"

Xiao Lou shook his head: "The clothes don't weigh as much as 10kg, so it shouldn't be this way. If a man and a woman enter this secret room, the difference in weight will be even bigger. Just relying on weight and clothes, there is no way to balance the electronic scale."

In the empty room, there are no tools except for the challenger.

How to balance the electronic scale?

Xiao Lou stroked his chin and fell into deep thought.
