Yuantai lowered his head and continued to play with the nine rings. He took off the first three rings and found that the fourth ring still needed the third ring on the shelf, so he reinstalled the first three rings.

  Tantrum value +1!

  Tantrum value +1!

 Patience, Yuantai installed the first three rings, but suddenly found that he was back to the starting point, and solved it again.

  Tantrum value +1!

  Tantrum value +1!

　Besides, Dr. Ali saw Yuantai with his head lowered and his face sullen, and he felt a sweat in his heart, "Yuantai..."

"Doctor, don't worry about me," Yuantai said with a serious and gloomy expression, staring down at the nine-ring ring in his hand, as if he was about to chew it, "I can do it."

 Let him explain it again and observe again, he doesn’t believe it...

  Tantrum value +1!

  Tantrum value +1!

Conan also sweated and decided to quietly provide some help to Yuantai. He turned to ask Chi Feichi, "Brother Chi just said that the rule Yuantai said is correct. To solve the fourth link, the third link must be on the shelf. Right?"

Bar?"

Chi Feichi understood that Conan wanted to use the old trick to give a 'hint'. He still lowered his eyes and stared at the wine in the glass without raising his head and said, "Well, to solve the fourth ring, the third ring must be on the shelf. The third ring must be on the shelf."

All the first rings are not on the shelf, the fifth ring requires the fourth ring to be on the shelf, the first, second, and third rings are not on the shelf, and so on.”

Conan felt relieved. Now Yuanta should know that he only mastered the first half of the law. The third ring is not enough on the shelf. He needs to put down the first two rings before he can put down the fourth ring.

Yuantai listened carefully, understood, and put the ring back on.

Take the first and second rings off the shelf, leave the third ring on, pass the fourth ring through the third ring, put the fourth ring down, look at the third ring left on the shelf, and think about Dr. Agasa

To solve the third ring, reinstall the first and second rings, put the first ring down, use the second ring to remove the third ring, reinstall the first ring, use the first ring to remove the second ring,

Then take off the first ring...

 Take off the front four rings from the shelf.

 “You succeeded, Yuanta!” Ayumi smiled.

 Shirane Kiriko applauded, "It's amazing!"

Yuanta exhaled, feeling a little tired, but still wanted to keep trying.

 To solve the fifth ring, the fourth ring must be on the shelf and the first three rings are not...

 Then we need to put down the front three rings, leaving the fourth ring to lower the fifth ring, then install the front three rings, lower the first and second rings, use the third ring to lower the fourth ring, and then install...

Dr. A Li saw that Yuantai had found the pattern, so he let Yuantai play, and talked to Chi Feichi who was drinking, "The pattern is very strong. After finding the pattern, the steps are just a little more complicated, and untying and putting on are

There is also a set of rules for a pair of reverse processes, right, Feichi?"

Chi Feichi took a sip of wine, put down the glass, nodded and said, "It's the same principle as the computer's Gray code..."

Beside them, Ida Yan and Kanaya Mineto, who were drinking, leaned in and listened, silent.

 Gray code? Why do they have a bad feeling?

Chi Feichi: "If the ring is represented by 1 on the shelf and 0 below the shelf, the leftmost ring can go up and down arbitrarily, the rightmost ring in the output data is 1, and the extra 0 on the right can be omitted, then it is 1, 11,

01,011,111,101,001,0011…”

 Ida Yan: “…”

　(ー△ー；)

 Who is he? Where is he? What are these people talking about?

 Jingufeng people: “…”

　(ー△ー；)

Can anyone understand this?

Haiyuan Ai nodded and said, "I know, convert it into binary and find its Gray code..."

Ida Yan and Jin Gufengren: "..."

They were wrong, they shouldn't have eavesdropped, they should have watched that little fat guy solve the Nine Links, then at least they could understand a little bit...

Over there, Yuantai has unlocked the five rings and continues amidst cheers.

Conan watched Yuantai sweating as he struggled with the nine-link chain. Although Yuantai's solution was relatively smooth so far, he was still worried, "Brother Chi, the further you get to the back ring, the more steps there are, right? Then solve the six-link chain."

need……"

“You can play the first and second rings at the same time, that’s 31 steps,” Chi Feichi paused, “Actually, if you want to unlock all nine rings, you have to play the ninth ring first.”

"In other words, the eighth ring and the upcoming ninth ring are left on the shelf. Take off all the first seven rings and proceed with the steps to unlock the seventh ring..." Conan's mind was stuck for a moment, and he couldn't help but look at Yuantai worriedly.

.

Over there, Yuantai lowered his head and tried to solve the sixth link. At some point, his mind got stuck and confused, and he became confused.

  Tantrum value +1!

  Tantrum value +1!

  Tantrum value +1!

Others looked at Yuantai Yi's chaos, their thoughts were confused, and their eyes were spinning with mosquito coils.

 The more confused Yuantai's thoughts become, the more irritable he becomes. The more irritable he becomes, the less he can find his way back to his thoughts. The more chaotic his thoughts become, the more...

 Then, the removed ring was knotted.

Fei Chi looked at the chaotic nine-link chain, thoughtfully.

These knots...it can figure out how to untie them.

 “Ahhhh!”

Yuantai shouted irritably and slapped the nine-ring ring on the table, startling the others.

 "Yuan, Yuan Tai..." Bumi was frightened.

Yuantai put down the nine-ring ring, threw it forward, and lay on the table with his face flat on the ground, with a depressed look on his face and dull eyes, "I won't play anymore, I won't play anymore... I won't play anymore..."

Conan was stunned again and again, this...

Chi Feichi almost drove someone crazy when he gave him a gift?

“Okay, okay,” Dr. Ali quickly comforted Genta, who was in a state of collapse. “The nine-link chain is difficult to solve, and the steps are cumbersome. As a first-year primary school student, being able to solve five of them is already very impressive!”

“Yes,” Shirone Tongzi nodded, “It’s really amazing, I almost got dizzy.”

"Really..." Yuantai straightened up doubtfully.

“It will get much better once you get familiar with it.” Chi Feichi followed to calm Yuantai’s mood.

 He doesn’t want to force the child to do anything wrong.

Yuantai looked at the nine rings on the table. He felt that the messy rings were shaking in front of his eyes again, and he immediately looked away, "Then I won't play with them either!"

“Genta, just take a rest,” Mitsuhiko said with a smile, “If I had known to read the instructions, it wouldn’t have been so hard!”

ˆ Yuantai: “……”

 He forgot the instruction manual...

Conan picked up the instruction manual that was thrown aside, looked down, and then looked at Chi Feichi, "Even if you follow the instruction manual to solve it, it will take a long time. Brother Chi, what is the fastest record challenge?"

 “More than three minutes and fifty seconds.”

  Chi Fei Chi picked up the Nine Links and decided to give it a try himself.

 Those who challenged the nine-link record were all Chinese. He remembered that in his previous life in 2012, someone broke the record in 161 seconds, and he still closed his eyes to solve it.

  Before this, the fastest record was more than three minutes and fifty seconds in 2003, and the fastest record in the world was still more than three minutes and fifty seconds.

The others saw that Chi Feichi was going to try it, so they moved closer to Chi Feichi.

“How long will it take Brother Chi to solve all the nine links?” Conan asked curiously.

 “I can’t break the record.”

Chi Feichi sorted out Yuantai’s messed up nine rings and put them on top at a speed that dazzled the others.

 No modesty.

The person who challenged the record of Nine Links was too familiar with Nine Links. Although he had played it in his previous life when he was bored, and his hand speed had been trained faster in this life, he was not good at it, so he really couldn't challenge it.

 Conan: “…”

 He just asked about the time, but the friend actually considered breaking the record...

However, looking at Chi Feichi’s hand speed and proficiency, he felt that he could indeed consider it.

Chi Feichi held the handle of the rack in his left hand and straightened his thoughts. The fingers of his right hand kept flipping between the iron rings, and the iron rings were being removed and put on one by one.

 Let’s go down the ninth ring first, that is, down 1, down 3, up 1, down 1, 2, down 5, up 1, 2, down 1, up 3...
