Card Room

Remember for a second

【Chapter 7, Number Puzzle】

After confirming that Yu Hanjiang who "refreshed the world customs clearance record of Hearts 2" in the announcement was someone he knew, Xiao Lou followed and asked, "This Yu Hanjiang, what should I do if I want to add him as a friend?"

Ace of Hearts smiled and said, "There is no such thing as 'adding friends' in the card world."

Xiao Lou changed his words: "How about teaming up with him to pass the level?"

A of Hearts explained patiently: "If you want to team up with anyone to challenge the secret room, you must buy a contract from the gatekeeper of the secret room, and establish a contractual relationship with the person you want to team up with. In this way, you will be tied to the secret room in the future. When he opens a new secret room, he will pull you into the world of the secret room, and similarly, if you turn over any card, he will also be pulled into the world of the secret room where you are."

"How much is the contract?"

"Purchasing the contract requires gold coins, you can get it in the process of clearing the level, please work hard to earn it in the follow-up secret room."

Hearing the gatekeeper's answer, Xiao Lou frowned helplessly - the currency circulating in this world is called "gold coins", and he can be said to be penniless at the moment. To form a team with someone, he still needs to spend money to buy a contract. He can't afford it now, not to mention that the D-level secret rooms are all single-person secret rooms, and there is no way to form a team.

Knowing that Yu Hanjiang also came to the card world, Xiao Lou's mood was quite complicated.

He should be happy to meet people he is familiar with in reality in this wonderful card world.

However, he came to this world because of a car accident, so it is very likely that Team Yu came to this world because of an accident - in the real world, Yu Hanjiang may have already sacrificed.

Thinking of the young detective captain who solved countless unsolved cases, Xiao Lou felt very sorry.

What happened to Yu team? No wonder he didn't reply to WeChat that day.

In any case, since he was reborn into this world, the only thing he can do is to live.

He thought that with Yu Hanjiang's ability, it would be no problem to successfully survive to the C-level secret room.

When you reach the C-level secret room, you can form a team to break through the level. At that time, he will find a way to earn some gold coins, buy a contract and ask Yu Hanjiang to form a team to play the Red Taoguan. With a professional criminal investigation expert like Yu Hanjiang joining in, the murderers of the Red Taoguan will definitely be invisible.

Xiao Lou put away his thoughts and said calmly, "Keep going."

As soon as he finished speaking, the "Diamond 2" playing card he had already drawn in his hand lit up with a familiar red light, and his entire body was suddenly sucked into the card room by a strange force——

***

The cramped, dark enclosed space is only four square meters in size, making it seem cramped for people to take two more steps.

The light of the entire secret room comes from an open flashlight hanging in the corner. A pendulum clock is hung next to the flashlight, and the hour hand above it points to 19:00 in the evening.

As Xiao Lou entered the space, the pendulum clock immediately began to swing regularly and made a clear "tick" sound.

A text prompt popped up quickly in the floating box.

——Welcome to the Secret Room of Square Piece 2 [Numeric Puzzle].

——Please find the organ as quickly as possible, crack the password, and open all the organ password locks.

——D-level secret room friendship reminder: Opening two combination locks is considered a clearance, and opening all combination locks is considered a perfect clearance.

——The time limit for customs clearance is 15 minutes. If you exceed the time, you will fail to pass the level. Please keep an eye on the pendulum clock on the wall.

The timing mode of Hearts Pass is similar to "Time Bomb-Bomb". The red countdown number will keep beating in the floating frame. When encountering difficult puzzles, coupled with the countdown, it will give people a huge psychological pressure. .

The timekeeping mode of the square piece is a pendulum clock. This secret room has a time limit of 15 minutes, and the pendulum clock hand in the secret room moves from 19:00 to 19:15, which means that the entry is over.

In a quiet and enclosed space, the ticking of the clock seems to be multiplied, which can seriously interfere with people's thinking.

Xiao Lou closed his eyes and forcibly ignored the clear bell ringing in his ears to calm himself down.

He picked up the flashlight in the corner and raised it to take a careful look around the house.

Xiao Lou has played many secret room games before. In some secret rooms, there will be a stepping mechanism on the floor. If you accidentally step on the wrong square, you may fall into the pit. So after he entered the secret room of the secret organ, his feet did not move, but stood in the middle of the secret room. First, he figured out where the organ that needed to be cracked was, and made sure that there were no problems under his feet and above his head, before he stepped forward and looked at the wall.

A lot of characters were painted on the four walls, and a large hole was dug under the wall, and there was a wooden box inside each, with a combination lock hanging on the box. The combination lock has four gears, which can be unlocked by dialing the gears to the correct number. At this time, all combination locks and gear numbers are in the initial state of 0000.

Four combination locks, open two to clear the level, you can pick the topic you are good at to crack, the D-level secret room is really friendly to the novice.

But what Xiao Lou wanted was a perfect clearance.

——Only after clearing the level perfectly, can he draw lottery and get the S card. There is definitely no harm in getting more cards.

Xiao Lou looked at the wall in front of him.

Under the illumination of the flashlight, a number nine-square grid appeared in the middle of the wall.

X/9/2

3/X/7

X/X/6

Among the mathematical reasoning questions, the 3×3 disk is called a “gong”, and the advanced nine-gong logic reasoning questions are called “Sudoku”, which is a professional

Questions that are often tested in quizzes.

Jiugong Sudoku is a 9×9 board with a total of 81 spaces. The challenger needs to deduce the numbers in the remaining spaces according to the known numbers, and satisfy every horizontal row, every vertical column, and every 3×3 single. Palace, all contain the natural numbers 1-9, and do not repeat.

At this time, Xiao Lou was facing a 3×3 single-government board.

He can even do 9×9 Sudoku, not to mention the 3×3 single house, which is not difficult for him.

In this house, the X in the four vacancies is the password.

The numbers filled in the nine-square grid include 1-9. The numbers that have appeared so far are 9, 2, 3, 7, and 6. According to the most basic rule of "non-repetition of a single palace", the missing numbers are 1, 4, 5, and 8.

How should these four numbers be arranged to be the password?

First look at the known items. The numbers in the third column are complete, 2+7+6=15. It is inferred that the rule of this nine-square grid is that the horizontal row and vertical column "sum is 15", then fill in 4 in the first row and fill in the second row. 5. Fill in 8 and 1 in the third row respectively, which satisfies all the rules of "sum is 15" for all horizontal rows and vertical columns.

The password is 4581.

Xiao Lou walked towards the box, picked up the combination lock and turned the initial password from 0000 to 4581.

With a light "pop", the box in front of him was opened - he unexpectedly found that there was a card in the box.

[Special effect card: Jiugongge]

Rarity: C

Description: You can get it in the treasure chest after completing the Jiugongge reasoning question in the secret room of the square piece 2.

Remarks: Throwing the special effect card Jiugongge to the designated position will immediately form a 3m x 3m Jiugongge disk, locking all targets within the Jiugongge range and making them unable to move for 9 seconds.

Number of times it can be used: 9/9

Xiao Lou's eyes lit up!

The secret room of hearts is a unified settlement of rewards in the personal space after customs clearance, and every time you unlock a trap in the secret room of square pieces, there may be a reward chest waiting for you. It's like playing a single-player game, turning on the machine, walking through the maze, and every time you unlock an area, you may get a treasure chest.

Jiugongge is a special effect card. Although it is only a "C-level" rarity, it has a large-scale locking control of 3×3 square meters. At the critical moment, the enemy can be immobilized in place for 9 seconds, and you can quickly escape!

This card, in conjunction with Tao Yuanming's Peach Blossom Spring, which he had drawn earlier, at least escaping for his life would be no problem.

The harvest of the special effect card was really an unexpected surprise. Xiao Lou cheered up and immediately walked to the left wall to continue solving the puzzle.

The math problems on this wall are slightly more complicated than the Jiugongge just now.

I saw four lines of reminders written on the wall—

4894=1236

9795=1645

7743=1412

8376=? ?

Xiao Lou just read the question once and quickly gave the answer.

When many people hear "number puzzles", they will subconsciously feel that they are not good at mathematics and cannot do it, but in fact, number puzzles do not test the ability of mathematical calculation, but the ability of logical reasoning - the key is to find the difference between numbers. between the rules.

Solving this problem requires careful observation.

Xiao Lou often plays secret room games, so he has a lot of experience in numerical reasoning.

The trick to playing number reasoning questions is to ignore the size of the numbers themselves and look at each number individually. For example, the prompt item of this question, 4894=1236, is easy to find by careful observation, 4+8=12, 9×4 =36, after the simple addition and multiplication of the previous number, it just matches the following 12 and 36.

The same is true for 9795=1645, 9+7=16, 9×5=45.

That is, the first two numbers are added to get the first two digits in the result. Multiply the last two numbers to get the last two digits in the result. The three prompt items all agree with the same law, which proves that the problem-solving idea is correct.

The reasoning result of the last 8376 is obvious, 8+3=11, 7×6=42, and the answer is 1142.

1142 is the agency password.

Xiao Lou walked to the treasure chest and quickly flipped the combination lock to change the gear number to 1142.

Sure enough, he heard a "pop", and the box was successfully opened in front of him.

There is still a card in the treasure chest——

【Special Effects Card: Mathematical Equation】

Rarity: B

Description: You can get it in the treasure chest after completing the equation reasoning question in the secret room of the square 2 machine.

Remarks: The effect of this card is very special. You can throw the mathematical equation to any specified target, so that the target is completely equal to the damage you receive. )

Usable times: 2/2

Xiao Lou: "..."

What's up with drawing a smiley face at the back?

Do you want to pull a pad when you die? Can the style of this card world be better?

It might be useful to force the other party to suffer equal damage to yourself, and die together with others? Xiao Lou twitched the corners of his mouth and put this card into the card bag.

The rarity of the Math Equation Card is B, indicating that the number of challengers to solve this problem is relatively small.

This kind of logical reasoning problem, it is very simple to find the rules, and if you can't find the rules, you can't solve it without breaking your head. It is really difficult for those challengers who have never played the secret room game or have been exposed to numerical reasoning. It is estimated that they will be confused when they see this question.

fine

D-class secret rooms can be selectively opened. Choose two out of four, the probability of finding a question that you know is quite high.

A prompt pops up in the floating box: "Have cracked two organs and reached the customs clearance conditions, do you want to leave the secret room of square 2? Yes/No"

Xiao Lou chose no without hesitation.

He turned around and walked to the next wall, hitting the light of the flashlight on the wall and continuing to crack the next trap.

——Perfect customs clearance is his pursuit!

The author has something to say: There is one more.

A few typos were fixed in the first few chapters, but the plot has not changed.
