Players please take your place [Unlimited]

"So this game is Jiu Lianhuan, isn't it?" Chen Kaijie excitedly said.

Xiao Muyu hummed, and just as she finished speaking, the black cloth that covered it was suddenly lifted, revealing the five nine-linked rings placed on it.

Shen Qingqiu stared at Nine Links, frowned and said: "The first reminder is really sinister, nine zombies, one ring, if it wasn't for the fact that it was a hands-on puzzle game and needed props, I wouldn't have thought of Nine Links Besides, it was so sudden, did it scare you?"

She was talking about you, but her eyes were fixed on Xiao Muyu, and her eyes were full of concern.

Xiao Muyu saw Su Jin looking at her from the side, so she just nodded lightly, "Yes."

Su Jin Zuo Tiantian had sharp eyesight and didn't say much, only Chen Kaijie who couldn't figure out the situation said with lingering fear on his face: "Yeah, this setting is too insidious, I'm still staring at the small screen nervously , As a result, several zombies rushed out from the side, scaring me out of my wits, and I didn’t know anything.”

Shen Qingqiu didn't make fun of Chen Kaijie, she was startled at the time, it just made her so daring, she took a step back to avoid it, and slashed through with a knife, and she found out that it was a fake as soon as she missed.

Fear will confuse the eyes and affect judgment, but Shen Qingqiu calmed down very quickly, and saw the information on it.

She has always been free and easy, thinking of Nine Chains, she doesn't bother to look at the things behind, after all, her points are scary, even if 5 points are deducted, she doesn't care.

Chen Kaijie said with some embarrassment: "I was terrified at the first reminder, and I didn't see anything. The second one was gray code, and I didn't know what it was. Thanks to that digital poem, I thought If the next one is Jiu, I guess Jiu Lianhuan."

Su Jin added: "The poem is rumored to have been written by Zhuo Wenjun to Sima Xiangru, and the last sentence was broken by Jiu Lianhuan, and the ten-mile long pavilion was about to be pierced. I knew the last sentence, so I wrote Jiu Lianhuan. I don't know anything about the gray code. mean."

Zuo Tiantian was a little happy, "When I was in college, my roommate liked to play Jiulianhuan. I tried it and couldn't solve it, so I searched it. It looked so complicated that I was dizzy.

But just remember what it said, the solution of Jiulianhuan is consistent with binary and Gray code.

I don't know what Gray Code is. When I saw this, the first thing I thought of was Jiulianhuan, so I filled it out. "

Several people were sharing their problem-solving process, Xiao Muyu listened carefully, and at the same time, they had already walked up to Jiulianhuan.

At this time, the broadcast voice continued to sound: "Congratulations to everyone who successfully guessed this round of the game, Nine Chains. Next, the second link will start, solving Nine Chains cleverly! Please listen to the rules of the game carefully. First: All living players must participate in the solution." Nine links, time limit 20 minutes;

Second, once it starts, before the system has no instructions, all personnel are not allowed to give voice guidance, manual assistance is not allowed, and it is not allowed to watch teammates step more than 10 steps. for game over;

Third, once someone makes a noise in violation of the regulations, 1 minute will be deducted directly, and 10 minutes will be deducted for the violation.

If the game fails, the failed team members will be eliminated directly and reduced to zombie rations.Note that once you take over, if the takeover player fails the challenge, the two will be eliminated together!

Please carefully study how to clear the level, give you 30 seconds to communicate briefly, and the game will be regarded as the beginning of the game once you move the nine chains! "

As soon as these rules were finished, everyone's face changed, especially the first rule, the implication is that if you want to not participate, you must be a dead person.

Isn't this a disguised form to lure and eliminate players who can't play?

Moreover, it basically cut off all the possibilities for them to rely on one person to clear the customs.

But this is not the time to be entangled in this rule, Xiao Muyu quickly said: "I have never played Nine Links before!"

The words were simple and powerful, Su Jin and the others trusted Xiao Muyu without hesitation, at that moment Su Jin and Shen Qingqiu raised their hands.

Zuo Tiantian said quickly: "I just played but failed to clear the level. It has been more than a year."

"I played it in school, but it's been years, and I'm not sure I can solve it in such a short time."

Xiao Muyu glanced at Shen Qingqiu, she and Su Jin shook their heads together, "I haven't touched it before."

Xiao Muyu's face was a little stagnant, but he quickly recovered his usual calmness.

Because of time, she spoke very fast, but she spoke clearly and fluently without any panic, which stabilized the hearts of a group of people to a certain extent.

But Chen Kaijie, who has played Jiulianhuan before, was sweating in his palms. As far as he knew, it was normal for him to play Jiulianhuan for the first time without guidance for four or five hours.

Those who are smart and have studied the method in advance, most of them will take three to four 10 minutes or even longer to play for the first time.

Ordinary people can only do it within 10 minutes after long-term training. According to his knowledge at the time, the fastest world record was 3 minutes and 30 seconds.

"Please remember the important point! The purpose of the Nine Chains is to untie all the rings. From right to left, there are nine rings in total, which are 1, 2, 3, 4...

9. Su Jin, Qingqiu, look, the upper ring and the lower ring come in and out from the middle of the pole.

The core rule of the Nine Links is just one sentence: If you want to go up or down this ring, then the previous ring must be on, and all the rings on the right besides it must not be on the pole.

For example, if you want to drop the 9th ring, then 8 must be on the top, 1 to 7 rings must go down, and the 7th ring must be down, then 6 must be on, and 1-5 must be lowered, in turn, can you understand? "

When Xiao Muyu said, everyone was looking at the blood-red Nine Rings in front of them, and they nodded quickly to express their understanding.

"So if you want to solve the latter, you must first solve the front. Our operation is to start from the 1st ring and go down to the 9th ring, and 10 rings can be dismantled in 5 steps. I will operate the first 5 rings slowly, and you follow me.

People who are slow to operate repeat the first three rings, don't be afraid and don't rush, trust me.

If you know the Gray code, you should remember that 1 means that it is on the ring, and 0 means that it is below the ring. There are a total of 341 steps in the nine-chain ring. The Gray code for the first step is 111111111, which represents the 341st step in decimal. "

As soon as I finished speaking, the countdown ended, and the 20-minute timer over there had already started.

Xiao Muyu didn't give a single extra look, and picked up Jiulianhuan decisively and lifted it up.Seeing this, Su Jin and the others quickly grabbed the nine-hole ring.

At the beginning, Xiao Muyu only demonstrated how to go down and up the ring, and when she got to the third ring, she stopped to let others practice.

Her hands moved very smoothly and slowly.This clear and unhurried movement, coupled with the resolute and encouraging eyes, made Su Jin, who was sweating just after listening to Xiao Muyu's words, calm down a little bit.It seems that it is not as difficult as imagined to operate.

Zuo Tiantian savored the core points of Xiao Muyu's words while practicing. After solving the third link with Xiao Muyu, she tried to solve the fifth link.

She succeeded once after stumbling, and she vaguely felt that she had found the trick, and Chen Kaijie over there had already started to disassemble the seventh ring according to his own memory.

The time passed by one minute and one second. At 2 minutes and 48 seconds, the original timing screen began to play numbers. At first, the first set of numbers was 111111111, then 111111110, and then 1111010, 111111011, but these four numbers were repeated over and over again. Number of groups.

Shen Qingqiu immediately stopped the movements in his hands and started staring at the numbers on it.

That is the gray code that Xiao Muyu mentioned, Shen Qingqiu has come into contact with it before.She has learned the conversion between it and binary, but rarely uses it, so she did not expect to encounter it here.

Just now, while following Xiao Muyu to familiarize herself with the movements and operating principles of her hands, she was thinking about what Xiao Muyu said. When she saw the number, the place where she was hesitant suddenly became clear.

In the 340th step, the binary value of 340 is 101010100. From right to left, 1 changes to 0, and it is converted into Gray code, which is 111111110, which just corresponds to the first step of Xiao Muyu's operation, and step 1 corresponds to The gray code is the third set of numbers displayed, the first ring and the third ring are both 339, that is to go to the third ring.Immediately following step 0 is to go to the first ring.

Shen Qingqiu is sensitive to numbers, even for this kind of binary conversion up to nine digits, she can quickly get the result.

Right now, she glanced at her Jiulianhuan, which should be 111100000 according to the status.

The first five rings are all down, and the next step is the seventh ring, which is step 7.

In fact, you don’t need to use the Gray Code in the future, just like Xiao Muyu said, if you want to get on or get on which ring, just go back to the previous one, and just drop all the others.

Just because the recursion must repeat the previous number of steps, it is easy for novices to get confused and take the wrong number of steps, resulting in a waste of time.

The Gray code will clearly tell you what to do at each step, and there will never be any mistakes. Therefore, the number of steps in the nine-series chain can be perfectly controlled to 341 steps, not more than one step, not less than one step.

As for Xiao Muyu, as a professional in the field of computer software, no one is more familiar with Gray code and binary than her.

What's more, Xiao Muyu participated in this kind of puzzle game when he was in high school, but he still solved it blindly with his eyes closed.

When it was confirmed that several of them would solve it, the dexterity of the fingers of those hands was amazing.

Su Jin and the others glanced at it, and found that Xiao Muyu didn't need to think about what to do next at all, and he didn't hesitate with his hands from the beginning.

One by one, the rings went up and down in her hand for a while, two up, one down, and the last one.

Now the timer shows that it is almost 5 minutes, and Xiao Muyu still has more than 30 steps.

Suddenly, the door of the stairwell on the second floor made a loud bang, shaking the entire fire door.

The faces of the five people all changed. What's going on?

Shen Qingqiu's hands kept moving, his eyes were already patrolling the door vigilantly, followed by another loud noise, the door shook again, something was about to come out from inside.

In this dungeon, there is no need to guess what will come out, Shen Qingqiu glanced at Xiao Muyu, put down Jiulianhuan, and walked towards Chen Kaijie.Chen Kaijie understood, and immediately summoned Tang Dao to Shen Qingqiu.

Xiao Muyu was also holding Jiulianhuan and staring at the door, Shen Qingqiu stretched out his hand and turned her head away, smiled at her, his eyes were reassuring, signaling Xiao Muyu to concentrate on solving Jiulianhuan.

Zuo Tiantian also quickly separated her mind and activated the cards to build the wall. Thirty seconds later, a wall appeared in front of the fire door, and she was secretly annoyed. At first, she didn't expect that a wall should be built to seal the door earlier.

This one-square-meter wall has limited effect. When the second piece has not been opened and condensed, the door has been breached. I don’t know how many zombies are crowded at the door, scrambling to crawl out.

Shen Qingqiu had Tang Dao in his right hand and a dagger in his left hand. Tang Dao attacked from a distance, and the dagger defended himself. The four zombies who were leading the battle just got out before she broke their spinal nerves and chopped off their heads.

She stood alone at the door of the firewall without saying a word, and Zuo Tiantian condensed two walls when she started, completely blocking most of the fire door.

It's just that there was a petite zombie inside, the moment the wall fell, it jumped up and passed over Shen Qingqiu's head.

Chen Kaijie's Tang Dao is a B-rank zombie with high body hardness, and it has been chopped so hard that its blade has curled. Shen Qingqiu's Tang Dao just opened a hole in its body, and confiscated the wound.

The zombie was very afraid of Shen Qingqiu, and after avoiding her, he didn't stop for a moment, and rushed towards Xiao Muyu who was still concentrating on solving Nine Chains.

Shen Qingqiu's complexion changed slightly, his feet quickened to follow closely, and at the same time the dagger in his hand was thrown out with all his strength, stabbing it precisely through the gap between the zombie's second cervical vertebrae, and the zombie that was about to pounce on Xiao Muyu immediately froze in place, stiff Falling down, the corpse was kicked by Shen Qingqiu before it fell to the ground.

At the same time, the last ring in Xiao Muyu's hand fell to the ground.Xiao Muyu didn't even look at it, letting the metal ring hit the ground with a crisp sound and walked towards Shen Qingqiu quickly.

Behind her, the timer froze at 5 minutes and 59 seconds, and it took Xiao Muyu just over three minutes to solve the Nine Chains by herself.At the same time, the second door began to vibrate again.

Xiao Muyu frowned, reached out her hand to stop Shen Qingqiu, and signaled her to continue explaining.Then she raised her hand and took out the mask, looked at Shen Qingqiu, and put it on without hesitation.

Shen Qingqiu stretched out his hand to stop her, but Xiao Muyu dodged it, her eyes were firm, and she glanced at the zombie.

This game is really not easy to reproduce zombies, it's too disgusting, so Shen Qingqiu can only be picked.

And this person is so powerful in combat, she also wants to know how powerful she is.

So Shen Qingqiu looked at the desolate and elegant Xiao Muyu in front of him with a complicated face and changed into his own appearance, which was indescribably weird.

Although his face is pretty, it's still so awkward for Xiao Muyu to become like this.

Throwing the dagger to her, Shen Qingqiu was still a little worried, wondering if Xiao Muyu would be comfortable with it.

Right now, it is the best choice for her to solve it quickly, otherwise Xiao Muyu's actions will be in vain.Once the zombies rushed in, it was impossible for one person to protect so many.

So Shen Qingqiu walked step by step according to the gray code in his heart. Because the calculation took time, Shen Qingqiu didn't walk fast, but the further she went, the faster her progress was. Because she didn't turn back, she had already surpassed Chen Kaijie successfully removed the 9th ring.

Seeing that Shen Qingqiu had walked to the third floor with Jiu Lianhuan, Xiao Muyu took a moment to look at her hand, and the murderous gray eyes softened.

It is obvious that Shen Qingqiu is using Engema to solve it, and her current ring status is 01111000, that is, 8, 7, 6, 5, all four rings are on it.

Enigma converted to decimal is 159, that is, the 159th step has been reached, and the enigma corresponding to the next 158th is 011010000, that is, the sixth ring is removed.

Shen Qingqiu will only get faster and faster according to this progress, but the situation of the remaining three people is very bad. Shen Qingqiu still has 158 steps left, but Chen Kaijie still has 187 steps, Zuo Tiantian is 197 steps, Su Jin barely kept up at 199 steps.

But time waits for no one, if the zombies rush out, I'm afraid they won't be able to take a step.

boom!The door was knocked again.

The author has something to say: This is just to popularize science for everyone, it’s okay if you don’t understand, just watch the fun.There were only 26 comments in the previous chapter, everyone, don’t forget, I love you all.

Let me talk about Jiu Lianhuan first. The core principle of the solution is that the two sentences Mu Yu said must be satisfied at the same time.

But those who are not skilled will have to grope for a long time to understand it, but Engma's solution is very clear. It takes at least 341 steps to put on the Nine Links, so you don't go wrong.

Putting them all together is nine 111111111, with 1 on the top and 0 on the bottom.

Therefore, the number represented by the first step of the ring solution should be 341 steps, and 341 into binary is 101010101, which is inconsistent with the state of the ring, so it is necessary to replace the binary with Enigma, the principle of Engma conversion, Looking from right to left, if the left side of the number is 1, it will change, and if it is 0, it will not change (the change means 0 is written as 1, and 1 is written as 0). Then the Engma of 101010101 is 111111111, a total of nine ones.

The number of steps is first converted into binary, and then rewritten into Engma. Engma can intuitively see which ring is on the top and which ring is on the bottom, and there is no wrong step.

But the unfamiliar conversion is too troublesome, I am also half-baked, I am learning and selling, please correct me if I have any questions.
