The fourth floor is decorated in a similar style to the first floor, with black walls and wooden floors, but the light is very bright, no longer illuminated by silver candlesticks, and the furnishings are completely different. Pen & Fun & Pavilion www.biquge.info

There are no purple veils around, but instead there are huge ones... Playing card!

54 playing cards, each one one tall! Densely packed in the room, Yuan Bin stepped forward and touched it with his hand, I don't know what material it was made of.

"Find the code to clear the customs, summon the birth gate, and open it with the silver key."

This is the latest passage to appear on the black cardboard.,Think.。。。 It's the final task.

At the back of these erected playing cards, there is a rectangular silver frame that is divided into five squares, each of which is just the right size to hold a giant playing card.

Yuan Wei observed the structure of the frame, "Look at this meaning, the so-called customs clearance password should be based on the number of playing cards, and this silver frame is used to place the password, right?" ”

"Isn't this too easy as the final hurdle? You see, five grids, that means the password is five digits, to choose five from this pile of cards to make the password, hum, fools can think, these five cards must be our fortune telling five cards "Yuan Bin's guess is not wrong, in the first level of divination, everyone in turn from the pile of cards selected five different suits of playing cards, this playing card is not only as the second level of hide and seek identity mark, but also as a sign of the fork in the echo house, and now if you know that the password is composed of five playing cards, Then it must be the five cards they chose.

King, Ace of Squares, King of Spades, Q of Hearts, 9 of Clubs.

Yuan Wei reminded Yuan Bin not to be so careless, although the lock password is composed of those cards, but I don't know the order of arrangement, and it can't be said to be simple.

Yuan Bin didn't care, the five-digit password, after knowing the numbers, even if he didn't know the order of arrangement, it was not difficult to solve it, couldn't he try it one by one?

But at this time, Xi spoke, "There is only one chance, when the five cards are framed at the same time, it means that the password is set, if it is wrong, the used five cards will disappear, which means that... ”

Zhao Ruiying followed his words and said uneasily, "It means... We can't summon the birth gate, we can't get out anymore."

So people were shocked, what are you kidding? Only one chance! What are the three more chances to enter your bank password?

Yuan Bin smiled and said tentatively: "That... That one.. Oba, you're going to give us a hint, right? ”

Xi glanced at him, "You guy is obedient in his left ear, and his right ear is out... Didn't I just say that? I won't give any hints in the last level, telling you that you only have one chance to do your best, and the rest is up to you."

"Don't bring it like this?!。。。。" Yuan Bin looked sad with a crying face, without any hints, and only gave one chance, how ridiculous it must be to accurately arrange the order of passwords!

Yuan Wei motioned for everyone to take all the playing cards they needed first, and then think about it slowly.

Several people spread out and searched the room for the corresponding five cards. The arrangement was irregular, and it took more than ten minutes to find out the five cards of different suits and move them to the frame.

Yuan Wei asked everyone to sit down and arranged, "Okay, let's start thinking about a reasonable order now, everyone can say a plan, and then we will make a comprehensive inference."

Yuan Bin took the lead in raising three hands, "If you want me to say, each card corresponds to our identity, everyone agrees with this?" I think it's sorted by our age."

Yuan Wei shook his head helplessly, Zhao Ruiying reacted similarly to him, staring at Yuan Bin like an idiot, "Are you too naïve?" Could it be as simple as that? Then let me ask you, that hand do you know it's expensive this year? Hey, even if it's sorted by age, from small to oldest or from oldest to smallest? ”

When Yuan Bin heard her analysis, he coughed twice and rubbed his nose with his fingers.

"Could it be in the order of the five doors of the Echo House? From left to right, who in your family remembers the order? Yuan Wei said.

Yuan Bin was originally quite embarrassed by Zhao Ruiying's refutation, but when he heard Yuan Wei say this, he sneered, "Ha!" You still call me naïve? Is there anything more exaggerated than me, in the order of the five doors? Then just open the door for us, let us go back, and what password do you set? Is that a password? That's a clear code! ”

Yuan Wei thought about it, it was indeed a bit direct, and the puzzle of the last level should not be so eye-catching to prompt in advance.

Although this Yuan Wei's idea was not refined enough, Zhao Ruiying continued to think and came up with a possibility: "Could the order of this password be the order in which we come out after completing the task when we are in the Echo House?" ”

Yuan Bin snorted coldly again, this time louder, and even more contrived, "Hmph~ Oh my God, Miss Zhao, are you still complaining about me with your IQ?" You can figure it out! When we were looking for task items in those five rooms, we all encountered some difficulties and obstacles, and mixed with a bit of luck, my task is to play mahjong to win the score, can the time be fixed for doing this kind of thing? I was the third to come out, and if I'm lucky enough to be the first to come out, will my card be moved from third to first? What do you mean, does this password change immediately? ”

Zhao Ruiying was about to argue, but Yuan Wei first said for her, "It's possible, this password is not fixed from the beginning, and it is very likely that it will be randomly generated according to the situation of our previous tasks."

Zhao Ruiying nodded, saying that this was what she meant, but Yuan Bin still felt a little embarrassed, and argued, "If the password is randomly generated according to our previous tasks, then why is it that level, why don't you combine the factors of other levels?" ”

"Isn't the Echo House the center of the building? It's normal that the chances of giving clues there are relatively high, and besides, aren't we discussing it now, and haven't it been finalized yet? ”

"Hey! I just think you're being too arbitrary, and you need to listen to other people's opinions... ”

"I didn't say I didn't listen to you, but could you please be a little more serious? Use your brain... ”

"Who is not serious? Hey, who do you say don't use the brain scripture? Don't forget that when you were in the Echo Room, you all had to sit there in a daze, and in the end it was the secret door I found in the wall! ”

"What are you yelling about..."

。。。。。。

Zhao Ruiying rubbed her temples and tried her best to endure the quarrel between the two Yuan brothers, just when she was about to reprimand herself, the originally quiet carriage on the side got up and floated to the middle of the two of them, raised two black ghost hands, opened the bow left and right, and slapped it on the face...
