The Secret Chamber of the Card Game

After confirming that Yu Hanjiang who "renewed the world clearance record of Heart 2" in the announcement is someone he knows, Xiao Lou immediately 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 break through the level?"

Heart A patiently explained: "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 contract with the person you want to form a team with. In this way, you will be bound in the future secret room. Set together. When he opens a new room, he will pull you into the world of the room, similarly, if you turn over any card, he will be pulled into the world of the room where you are.”

"How much is the contract?"

"Purchasing the contract requires gold coins, you can get it during the process of breaking through the level, please work hard to earn it in the subsequent secret room."

Hearing the gatekeeper's answer, Xiao Lou pinched his brows helplessly—the currency circulating in this world is called "gold coins", and he can be said to be penniless at present.Forming a team requires money to buy a contract, which he can't afford 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, so he can only wait until he earns money later.

Knowing that Yu Hanjiang has also come to the card world, Xiao Lou's mood is quite complicated.

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

However, he came to this world because of a car accident, so Team Yu probably had some accident when he came to this world—in the real world, Yu Hanjiang may have died.

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

What happened to Team Yu?No wonder I didn't reply to WeChat that day.

In any case, since he was reborn into this world, the only thing he could do was to survive.

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

You can form a team to break through the level in the C-level secret room.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 go to Hearts Pass. With a professional criminal investigation expert like Yu Hanjiang joining, the murderers of Hearts Pass will definitely have nowhere to hide.

Xiao Lou put away his thoughts and said calmly, "Go ahead."

As soon as the words fell, the surface of the "Diamond 2" poker card he had drawn in his hand glowed with a familiar red light, and his whole body was suddenly sucked into the card chamber by a strange force——

***

The cramped, dark enclosed space is only four square meters in size, making it feel awkward to take two extra steps.

The light in the entire secret room comes from the turned-on flashlight hanging in the corner, and a pendulum clock hangs next to the flashlight, and the hour hand on 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 quickly popped up in the floating box.

——Welcome to the secret room of Square 2 [Number Puzzle].

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

——Friendly reminder of the D-level secret room: 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 limit, you will fail to pass the level. Please keep an eye on the pendulum clock on the wall for timing.

The timing mode of the heart level is similar to a "time bomb". The red countdown number will always jump in the floating frame. Encountering difficult puzzles, coupled with the countdown, will give people a huge psychological pressure virtually.

方片关的计时模式却是摆钟。这个密室限时15分钟，密室里的摆钟指针从19:00走向19:15，则代表闯关结束。

In a quiet and closed space, the ticking sound of the clock seems to be multiplied and magnified, which will seriously disturb people's thinking.

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

He picked up the flashlight in the corner and took 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 a wrong square, you may fall into the pit.So he didn't move his feet after entering the mechanism secret room, but stood in the middle of the secret room, first figured out where the mechanism to be cracked was, and made sure that there were no problems under his feet and above his head before he took a step forward and looked at the wall.

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

There are four combination locks, if you open two, you can pass the level. You can choose a topic you are good at to solve. The D-level secret room is indeed more friendly to novices.

But what Xiao Lou wants is to clear the level perfectly.

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

Xiao Lou looked at the wall directly in front of him.

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

X/9/2

3 / X / 7

X/X/6

In mathematical reasoning questions, a 3×3 disk is called a "palace", and the advanced nine-square logical reasoning question is called "Sudoku", which is a frequently asked question in professional quiz competitions.

Jiugong Sudoku is a 9×9 disk with a total of 81 spaces. The challenger needs to deduce the numbers in the remaining spaces based on the known numbers, and satisfy each horizontal row, each vertical column, and each 3×3 single Palaces, all contain natural numbers from 1 to 9, and do not repeat.

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

He can even do the 9×9 Sudoku puzzle, not to mention the 3×3 Sudoku puzzle, which is no difficulty for him.

In this house, the X's in the four vacancies are the password.

填入九宫格的数字包括1-9，目前已经出现的数字是9、2、3、7、6，按照最基本的“单宫不重复”规则，缺失的数字是1、4、5、8。

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

Look at the known items first, the numbers in the third column are complete, 2+7+6=15, infer that the law of the Jiugongge is that the horizontal row and vertical column "sum to be 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 the rule that the sum of all horizontal rows and vertical columns is 15.

The password is 4581.

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

With a soft "snap", the box in front of him was opened - he unexpectedly discovered that there was actually a card in the box.

[Special Effect Card: Nine Palaces]

Rarity: C

Description: It can be obtained in the treasure box after completing the nine-square-grid reasoning question in the secret room of the square 2 mechanism.

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

Available times: 9/9

Xiao Lou's eyes lit up!

The Red Peach Chamber of Secrets is a unified settlement of rewards in the personal space after customs clearance, and every time you unlock a mechanism in the Square Chamber of Secrets, there may be a reward chest waiting for you.It's like playing a stand-alone game, turning on the mechanism and walking 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 "C-level" rarity, it has a large-scale foot-locking control of 3×3 square meters. At critical moments, it can freeze the enemy in place for 9 seconds, and you can quickly escape!

This card, combined with Tao Yuanming's Tale of the Peach Blossom Spring that was drawn earlier, at least escape is not a 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 only read the question once, and quickly gave the answer.

When many people hear "number puzzles", they will subconsciously feel that if they are not good at mathematics, they will definitely not be able to solve them. between the rules.

To solve this kind of problem, we must observe carefully.

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

The skill of playing digital 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, can be easily found by careful observation, 4+8=12, 9×4 =36, after simple addition and multiplication operations, the previous numbers just match the following 12 and 36.

9795=1645也是同样，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 rule, which proves that the thinking of solving the problem is correct.

最后一个8376的推理结果，显而易见，8+3=11，7×6=42，答案是1142。

1142 is the agency password.

Xiao Lou walked to the treasure chest, quickly turned the combination lock, and changed 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 Effect Card: Mathematical Equation]

Rarity: B

Description: It can be obtained in the treasure box after completing the equation reasoning question in the secret room of the square 2 mechanism.

Remarks: The effect of this card is very special. You can throw a mathematical equation to any designated target, so that the damage received by the target is exactly equal to that of yourself. )

Available times: 2/2

Xiao Lou: "..."

What's the situation with drawing a smiley face behind the good one?

Do you want to pull a back?Can the painting style of this card world be improved?

Forcing the other party to suffer equal damage to oneself, maybe it is useful when you die with others?Xiao Lou twitched the corner of his mouth, and put this card into the card bag.

The rarity of the math equation card is B-level, which means that the number of challengers who solve this problem is relatively small.

For this kind of logical reasoning question, it is very easy to find the law, and if you can't find the law, you can't solve it even if you want to break your head.It's really difficult for those challengers who have never played secret room games or digital reasoning. They may be confused when they see this question.

Fortunately, the D-level secret room can be turned on and off selectively.Choose two out of four, and the probability of finding a question you know is quite high.

A prompt pops up in the floating box: "Two organs have been cracked and the clearance conditions have been met. 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, shining the light of the flashlight on the wall, and continued to crack the next mechanism.

——Perfect customs clearance is his pursuit!
