The Secret Chamber of the Card Game

Xiao Lou quickly solved the number puzzles on the two walls. It only took him 30 seconds at this time. The hour and minute hands on the pendulum clock still pointed to 19:00, and only the second hand pointed to 30 seconds.

It took 30 seconds to solve two math puzzles. Thanks to Xiao Lou who played a lot of secret rooms and has rich game experience, he could think of the solution as soon as he saw the problem.

The harvest of the two special effect cards made Xiao Lou full of motivation. After putting away the cards, he immediately walked to the third wall.

The questions on the third wall are different from the first two.

I saw four black Chinese characters written on the wall——

Tian, ​​Wang, Qi, Ri

There are no hints for this question, only imagination.

The four Chinese characters represent the final password. It cannot be as simple as counting the strokes of the Chinese characters directly. If it is counting the strokes, just write a few characters, not the four characters on the wall.

If you want to convert Chinese characters into numbers, you must find what they have in common.

Xiao Lou shined the light of the flashlight on the wall, observed carefully for more than ten seconds, and quickly came to a conclusion——

Don't regard them as Chinese characters, let alone think about surnames and phrases, but simply regard them as "graphics".

What these four figures have in common is that there is a "symmetry axis" that can be folded in the middle of each figure.

Tian, ​​folded symmetrically from the middle, will become the number 8.

King, folded in half from the middle, will become the number 3.

屮, after folding in half is the number 4.

Day, folded in half up and down, becomes the number 0.

——The four characters all have a symmetry axis, and they all happen to turn into numbers after being folded in half. This is the "logic" of this puzzle.

Without hesitation, Xiao Lou adjusted the gear on the combination lock to 8340 four digits.

As he expected, there was a crisp unlocking sound, and there was still a card in the treasure chest——

【tool card; folded paper】

Rarity: A

Description: It can be obtained in the treasure chest after solving the Chinese character puzzle in the square 2 secret room.

Note: Ever played origami?Use your rich imagination to fold this piece of paper into the shape you want, and it can be quickly enlarged and turned into a real thing.For example, if you fold a paper boat and put it in the sea, it will become a small boat.Fold out a horse, and you can also have a horse mount.It is not recommended to fold an airplane, because with most people's origami skills, the folded airplane is easy to crash after being enlarged and turned into a real one.

Number of uses: Such a powerful folding paper, unfortunately, can only be used once.

Xiao Lou can only fold the simplest paper airplane, even if it is scaled up a hundred times, it cannot fly with people, and he can't make other origami at all.It's better to put away this card first, and then give it to someone who is proficient in origami games in the future. Anyway, it is A-level rarity, and the function of turning into real objects is also very strong, so it cannot be wasted casually.Folding a car or a boat at a critical moment can be used in emergencies.

Xiao Lou put the card "Folding Paper" into the card bag, and turned around to solve the last puzzle.

There is one treasure chest left, open it to pass the level perfectly.

He shined the light of the flashlight on the last wall, and saw a lot of messy arrow symbols drawn on the wall——

←↓→↓←

→↓←↓→

←↓↓→↑←

→↓↓←↑↑

Xiao Lou raised the corner of his mouth slightly at this moment.

He happened to do this kind of subject.

At that time, he was playing a vampire-themed escape room game with his friends, and encountered a similar mechanism in the secret room, but instead of arrow symbols on the wall, there were English characters, such as RDDLUU, where U stands for Up, D stands for Dowm, and L It stands for left, and R stands for Right, which also means the four directions "up, down, left, and right".

What does up, down, left, right have to do with numbers?

As long as you stretch out your finger and write in your palm according to the rules in the prompt, you will know.

←↓→↓←, lower left, lower right, lower left, written 5.

→↓←↓→, lower right, lower left, lower right, written as 2.

←↓↓→↑←, the answer is 6; →↓↓←↑↑, the answer is 0.

The arrow code for this wall, the final result is 5260.

Xiao Lou quickly turned the gear of the combination lock to the four numbers of 5260, successfully opened the treasure chest, and got the last card of the secret room of 2 pieces of squares.

[Tool Card: Four-way Arrow]

Rarity: A

Description: It can be obtained in the treasure chest after solving the arrow puzzle in the square 2 secret room.

Remarks: It is flexible to use, especially when you encounter a maze, you can use the arrows to give some hints to your teammates so that they do not go into a dead end.The tool card has extremely high viscosity and can be stuck anywhere on the ground, branches, buildings, etc.When the tool card is left in place, seven colors can be customized to prevent people with poor eyesight from seeing it.

Number of uses: unlimited.

Xiao Lou read the description again, and found that the "four-way arrow" tool card mentioned a key word—maze.

This shows that in the future cube secret rooms, it is very likely to encounter a maze full of organs!

Moreover, this card clearly mentions "teammates", which proves that the maze in the later stage is indeed a multi-person team-up and multi-line exploration mode.Perhaps if one person steps on the wrong mechanism, all his teammates will be shot into hedgehogs by the arrow array.

If the square piece of secret room develops in the direction of a "mechanism maze", challengers will not only have to find a way out in the maze, use their brains to solve puzzles and open the correct mechanism, but also face the possible punishment of opening the wrong mechanism at any time.Rain of arrows, knife formations, boulders, puddles, poisonous mist, flames... There are too many ways to punish the mechanism, and the difficulty of the later stage of the square chamber of secrets will exceed his imagination.

Xiao Lou was thinking, at this moment, two lines of prompts popped up in the floating box.

——Congratulations to Xiao Lou who perfectly cleared the D-level secret room [Number Puzzle Map] in 58 seconds and scored more than 99.9%!

——The evaluation of this customs clearance is S. If you complete the customs perfectly, you will get an additional chance to draw a lottery. Please return to your personal space to settle the rewards.

When Xiao Lou saw the prompt of "Perfect clearance", he confidently pressed the "Exit" option in the floating box and returned to his personal space.

At the same time, square piece 2 is in the secret room.

Looking at the pile of equations on the wall, Yu Hanjiang frowned slightly.

He hates mathematics the most. When he sees something like 4894=1236, he just feels a splitting headache.

At this moment, a large red character suddenly appeared in the floating frame above the head——

Congratulations to the challenger [Xiao Lou] for perfectly clearing the square 2 secret room [digital puzzle] in [58 seconds], breaking the world record for the square 2 secret room!

Yu Hanjiang, who hadn't solved a problem in one minute: "..."

After entering the secret room, it takes time to move and dial the password gear before the four walls. Cleared the level perfectly in 58 seconds and solved four problems. In other words, the average time for Xiao Lou to solve each problem was no more than 10 seconds.

This Xiao Lou, the speed of deciphering the digital mechanism is too fast, right?

Yu Hanjiang frowned and looked at the announcement again.

The Xiao Lou he knew was a professor at the Department of Forensic Medicine of the Medical University.

The first contact was because a girl from the University of Medical Sciences fell to her death. During the investigation, I heard from my classmates that her last class happened to be Professor Xiao's class.The students spoke highly of Professor Xiao. At first, Yu Hanjiang thought that Professor Xiao, who is highly respected by the students, should be an old expert in his 50s or [-]s. He didn't expect Xiao Lou to be so young.

It happened to be raining on the day Xiao Lou came to the police station to take notes.

The man's black hair was soaked by the rain, and it stuck to his ear, making his face very handsome.His eyelashes were long and thick, with some rainwater on them, and there seemed to be a layer of gentle water in his black and clear eyes.

He was wearing a white shirt, and the rain-soaked clothes were stuck to his body, but he didn't look embarrassed at all. The man's standing posture was always upright and upright. I feel kind.

Yu Hanjiang has come into contact with people from all walks of life. Xiao Lou's temperament is undoubtedly unique-gentle, elegant, personable, and talented. These are the evaluations of his students. The students of the Medical University regard him as a male god. It is said that his Every class is full of seats, and in a university where the rate of skipping classes is extremely serious, there are actually students from other departments who come to observe his class.

During the process of taking notes, the man was always calm and composed, and it could be seen that he had a very high psychological quality and was very self-cultivated.

Yu Hanjiang's first impression of him was very good.

The case of the girl falling from the building was quickly found out. I thought that the two had never met again, but the serious crime team encountered a poisoning case of a nasty nature. When Yu Hanjiang sent the poison to the forensic identification center, he met Xiao Lou again.

The two became acquainted with each other because of the poisoning case, and became friends with each other. Xiao Lou helped a lot during the investigation of the case. Yu Hanjiang wanted to invite him to dinner, but it happened that the Spring Festival was approaching, so the dinner was postponed until Xiao Lou came back.

Unfortunately, on the seventh day of the Lunar New Year, Yu Hanjiang did not have time to meet Xiao Lou...

The familiar name brought countless memories to his mind suddenly, Yu Hanjiang took a deep breath and quickly stabilized his mind.

Being able to perfectly pass through the digital mechanism secret room in 58 seconds is obviously a master of digital reasoning games - is this Xiao Lou the same person as the young forensic doctor I know?Yu Hanjiang couldn't be sure.

He only knew that Xiao Lou was well received in school, but he didn't know whether he often played puzzle games in private.

Perhaps, in the future, we can find an opportunity to get in touch with this Xiao Lou?

Yu Hanjiang put away the chaotic thoughts in his mind, and continued to focus on the math puzzle on the wall.

***

Xiao Lou, who returned to his personal space, also saw the news that he had "renewed the world record for the secret room of square 2".

He was a little surprised.

A question in 10 seconds is a normal operation for him.After all, he has played too many secret room escape games, and the most common mechanism in the secret room is the digital mechanism.

Maybe among the people who come to the card world, it is rare to have such a strong psychological endurance like him, and even rarer are people who often play number puzzle games, that's why he got a bargain and broke the world record?

The question about the square 2 secret room is actually not difficult. Ignore the interference of the ticking sound of the clock, calm down and observe carefully. As long as you find the logic of the numbers, you can get the answer quickly.

In the 15-minute digital-themed mechanism secret room, Xiao Lou perfectly cleared the level in just 58 seconds.

What card will be drawn for this perfect customs clearance?

Seeing the green words "Cleared" appeared in the lower right corner of [Diamond 2] on the card wall, Xiao Lou said calmly, "Where is the gatekeeper of the Diamond Chamber? Come out and meet."
