Through the fabric of his sleeves, Sukhoi could feel Xiang Nanxing's cold and stiff fingers, and he understood the feeling, it was like being snatched of blood from his whole body in a few short minutes.

"Do you want to come first? I think it's still ......."

He hesitated whether to hand over the small paper stick in his hand or stick to his original plan. For a while, he couldn't tell whether Xiang Nanxing's actions at this time really had the intention to try, or did it mean that he had seen through Sukhoi's thoughts and planned to strike first? You must know that in this plan, the first person who does it has a good chance of successfully fooling around, but from the second person onwards it is inevitable that he will receive special attention from others, at least the first person will pay close attention to see if he actually presses the button. In this case, if Xiang Nanxing came up with the same plan, he would definitely come to grab the first place.

However, judging by the temperature of his fingers, he seemed to be really afraid of something...... Could it really be that he just had a burst of courage and wanted to come and open the way for everyone?

Sukhoi thought as he paused, but unconsciously clenched the small paper stick forward. He suddenly thought that such an attitude didn't seem to be friendly, and he was thinking about whether to relax, but he saw Xiang Nanxing's hand unexpectedly continue to stretch forward. In the shocked eyes of everyone, Xiang Nanxing's outstretched index finger was already hanging directly above the password disk.

Then, without hesitation, it lowers and presses a key thoroughly.

"Ahh

At this moment, Sukhoi screamed and jumped to the side in embarrassment, as if he was hiding from some plague god. His reaction was also fast, you must know that Xiang Nanxing, who reached out and pressed the button, was next to him, and the bodies of the two were somewhat sticky, in case the button was wrong this time, and the trigger mechanism was the same as the last time, then wouldn't he also be implicated by the electric shock.

However, this time, Xiang Nanxing stood there decently, unscathed. What's even more surprising is that half a second after he pressed the button, they suddenly heard a soft "pop" sound.

In the silence, such a strange soft sound was particularly noticeable. However, the mystery was soon revealed, because in the next second, they saw the door of the safe pop out a little, revealing a gap.

Xiang Nanxing pressed just now, and he successfully cracked the password!

"This ...... How do you do it? ”

Not only Sukhoi, but even Ye Hua and Chris widened their eyes in surprise. Only Saiguang in the distance was still persistently doing cardiopulmonary resuscitation for Saiwei, as if he didn't care about everything that happened here.

"I'll talk about that later."

Not bothering to answer these questions, Xiang Nanxing pulled the door of the safe open. But when he saw the piles of things inside, even he felt quite tricky.

"I'm in trouble." He frowned and reached inside, grabbed the contents and pulled them out. I only heard a loud noise, and Xiang Nanxing grabbed a large number of keys directly. These keys come in a variety of shapes, from the newer snap locks to the older ones. The keys and keys hooked on each other like cogs clenched together, and it took a lot of effort to remove them.

Sukhoi and the others looked at the keys piled on the ground in amazement, and it wasn't until Xiang Nanxing urged several times that they hurriedly squatted down, helped dig them out of the safe, and then dismantled them.

"No, wait, don't take it out yet." Xiang Nanxing suddenly thought of something, "Let's use the current comparison, we have to find out which one is different, so let's just throw aside those that can be paired in pairs first, and reduce the number before considering anything else." ”

He hurried to work, but Sukhoi's movements suddenly stopped. He raised his head and looked at Xiang Nanxing coldly: "Wait, how do you know the solution to this puzzle?" ”

Ye Hua and Chris's movements also stopped. What Sukhoi said at this time was what they wanted to ask, and not only that, but they also wanted to know which button Xiang Nanxing had pressed just now, and why they would choose the correct answer.

"Time is running out, let's hurry up ......"

"No, if you don't say it, we won't do anything." Sukhoi would have simply thrown away the keys in his hand.

Xiang Nanxing glanced at him deeply, then looked at the two people who also put down the key behind him, and finally let out a long sigh.

"Okay, then I'll cut it short." He said, "Do you remember, when the host introduced the game, he said that the name of the game is 'ONLY ONE', which translates to the only meaning. ”

Sukhoi snorted, "Just a name." ”

Xiang Nanxing nodded: "Yes, it's just a name, but think about the last sentence that the host said before cutting off the signal." He said there was the only hint in the room. This hint is the key to solving the puzzle. ”

"But didn't he finish speaking?" Chris said.

"No, he's done." Xiang Nanxing said word by word, "There is a hint of 'unique' in this room." 'Unique' itself is not just the name of the game, it's also a hint, and everything here points to the word, and the same is certainly true when it comes to passwords. ”

When he said this, Sukhoi subconsciously looked down at the password disk, indeed, the unit password that is almost impossible to appear elsewhere is placed in front of their eyes, if it is not for the response to the point of "unique", it is difficult to imagine that anyone would design the safe like this. However, this correspondence alone is not enough to explain Xiang Nanxing's success in solving the puzzle just now.

"......'Unique,'" Chris pondered, "which of the ten numbers from zero to nine is unique?" 2 is the only even prime number, zero is the only number that is neither positive nor negative, but the fingerprint is three, five, seven, eight, which ......"

"You're ignoring a really special key. It's not a number, it's a button. Xiang Nanxing's fingertips lightly tapped the one he had just pressed, but it was under a bunch of numbers, and it was taken for granted as the "confirm" button.

"The answer to the password disk is very simple, but it just hit the blind spot of many people's psychology, and many people have formed an inertia for entering the password, that is, enter the number first, and then click the confirmation button." Xiang Nanxing explained, "But if you think about it carefully, you will find that this password disk does not need this at all, because the confirmation key is to correspond to the rollback key, so that people can modify it after entering it, and finally confirm the submission." In the case that it cannot be modified, there is no need to emphasize the action of 'confirming' at all. ”

Of course, it is not excluded that its modification mechanism is directly overwritten with new numbers, and it is true that this is also the convenience of single-digit passwords. However, thinking about Saiwei just now, he touched the mechanism when he pressed the number button, and he didn't even have a chance to cover it with other numbers. This is enough to show that the judgment of the cipher disk for the input data is a one-time thing, as long as the wrong number is pressed, the mechanism will be activated immediately, without confirmation. ”

Speaking of the second half, Xiang Nanxing's tone became lower and lower, and he even carried a little weakness. As for the large part of the reasoning he just mentioned, in fact, a lot of it was thought of when he saw the cipher disk, but he couldn't fully verify the various situations at that time. And Saiwei's attack just now provided him with the most crucial information, so that the final answer can be confirmed.

From this point of view, Xiang Nanxing seems to be using Saiwei.

Fortunately, Saiguang didn't notice this, and the three people in front of him didn't seem to think in this direction. Xiang Nanxing said it, it was reasonable, and they suddenly felt that their hope for customs clearance had increased greatly. Sukhoi took the lead in crouching down and picking up the key again, and Ye Hua and Chris hurriedly did the same.

According to Xiang Nanxing's theory, the second puzzle is obviously "unique". That is to find the one in a pile of keys that is different. Although there are many keys in front of you, the number is still limited after all, and if you compare them with a few people, you will definitely be able to find them, all you need is accurate eyesight, plus quick hands and feet.

It's just that the key is here, and what about the lock hole that needs to be inserted?

Xiang Nanxing was thinking, and Sukhoi was also thinking about it, but unlike the former, he still had men to send. After a moment's thought, he patted little Chris on the shoulder and said, "You go around this room and see if you can find a small hole in the shape of a keyhole...... Remember, clues are 'unique', so the location of this keyhole may also be related to the clue, so you can leave this aspect of the feature a little more. ”

Chris took the order to step back, walked briskly around the room, and began his mission alone. At the same time, Xiang Nanxing and the others also began to work hard to concentrate, and opened their eyes wide and turned over the key. They pull one out of a pile of keys and try to quickly find the other one they correspond to, then toss them aside in pairs. These keys come in a variety of shapes, large and small, some of which are easy to pick and choose from, but some of the popular styles look similar, and they are quite draining to identify.

What's even more tricky is that what Xiang Nanxing just took out was only part of the box, and the real big head was still in the box. As soon as they thought of this, everyone felt that their hearts were at a loss: in less than an hour, not to mention the puzzles behind, they might not have time to pass the key comparison level. If they finally find out the true meaning of the clues, but fail to clear the level because they can't catch up, each of them will be very unwilling.

The thought lingered, so they just tried to concentrate, but they couldn't.

On this basis, Xiang Nanxing has an extra layer of more complex emotions. Luckily, it doesn't look like anyone wants to go over there yet. He thought to himself, a little lucky, and unconsciously set his eyes on the five small indicators above the red button next to the exit.

At this time, they were still in the same condition as when they first entered, and they were all dark. This click shattered one of Xiang Nanxing's beautiful fantasies. He had thought that the lights might correspond to the number of puzzles, and that for each one solved, the red light on it would turn on. However, it seems that this is not the case.

In retrospect, Matsumoto Makoto said that he only said "let the five red lights come on" at the time, and did not mention the question of how to light them up. All the moderators never lie about the rules, but some will always find ways to withhold the most important information or mislead the player in the wrong direction. Unfortunately, that's what happened to them.

Xiang Nanxing clutched the key tightly, and his palms ached. He already had the answer to the end of the game, but he had to keep it a secret alone, and he couldn't tell anyone about it even if his chest ached. Think about the "only" prompt, the content implied behind these five indicators, maybe what he wants to see in the end is a worst ending that no one wants to think about.

And there is little he can do about it.
