"If it goes on like this, it's definitely too late!"

Ye Hua slammed the key to the ground and stood up impatiently. His back was already soaked with sweat, and his forehead was covered with visible droplets of sweat. Of course, this is not because of how laborious the picking work is, but in this airtight environment, any bit of irritability in the heart will be magnified and finally manifested honestly physically.

Xiang Nanxing and Sukhoi are not much better, but they have not yet reached the point where Ye Hua is sweating like crazy. Compared to Ye Hua, who didn't expect that layer at all, they at least knew that the current irritability was somewhat due to the nerve gas diluted into the air, and with such psychological preparation, they could relatively retain some more rationality.

However, this is still meaningless, just like Ye Hua said, it will definitely be too late to go on like this.

"Special keys can be quickly sorted, but popular models can only be compared with the naked eye, and it takes a lot of time to find each pair." Sukhoi wiped the sweat from his forehead and turned his head to look at the countdown on the other side, "There are less than thirty minutes left, and it definitely won't work at the current rate." ”

Xiang Nanxing nodded, and at the same time glanced at Saiguang not far away, who was still doing heart compressions for Sai Wei persistently, as if as long as he continued to do this, his eldest brother would get better. The time on the LCD has come to a second point, which means that half of the time left for them to solve all the puzzles has passed.

However, what is desperate is that the five indicators above the red button have not even lit up yet.

"Damn! I didn't expect that the safe can't be considered a puzzle, what the hell is going on with these five indicators! ”

Sukhoi noticed Xiang Nanxing's gaze, followed it, and then couldn't help but scold. Ye Hua also turned his head to look over there at the same time, revealing a worried look. Xiang Nanxing silently observed him on the side, this tall and thin young man had always given people a very calm and silent second-in-command image before, but at this time, as the situation changed, his image gradually collapsed, and his calm and rational appearance was torn off, revealing the fragility and hesitation that belonged to the human side underneath.

This is the terrible thing about the game, just like Lorraine before her, who chose to kill to save herself in a life-and-death situation, completely abandoning the side that sacrificed herself to save her teammates just a few dozen minutes ago.

Xiang Nanxing was worried, thinking that he didn't know when he would see the scene of these people changing. In contrast, only the youngest Chris was in a state of serious uneasiness from beginning to end, and his panic was consistent from the beginning, which was the proper performance of a person with this experience, and he did not hide it. At this point, it really looks like it's a lot safer.

And at this time, it was he who brought rare good news to everyone.

"Found it!" There was a joy on his flushed face that couldn't be hidden, "There's a keyhole under the sofa, you can see it after moving the sofa a little bit!" ”

"Great!" Sukhoi stood up abruptly, hugged him tightly, and slapped his free right hand on his thin back, his excitement overflowing. Ye Hua is more pragmatic. As soon as he heard the news, he immediately bent down and grabbed a few keys in one hand, spread his long legs, and walked briskly in the direction of the sofa. Xiang Nanxing followed him, holding a few keys in his hand that he hadn't finished picking just now.

When he got closer, he saw Ye Hua trying, trying, and throwing a handful, and the look on his face began to become impatient. Seeing the various shapes of keys he threw away, Xiang Nanxing's heart suddenly had a guess, he walked over and handed over a key from Ye Hua's shoulder: "Try the shape of this one, right." ”

Ye Hua raised his head and looked at him deeply, and only after two seconds did he reluctantly take the key and insert it into the hole. The opening of this keyhole is closed by two spring plates, and only when the key is inserted will it be separated to the left and right, and at other times it is impossible to directly observe the situation inside, so they can only eliminate those keys that do not match the shape at all by trial insertion, and then look for the correct ones from the keys that can be inserted a little bit.

And the key that Xiang Nanxing handed over at this time went in a little as soon as it was inserted, which showed that although it was not the correct one, at least it was the same type in style.

"Sure enough." Seeing the results of Ye Hua's experiment, Xiang Nanxing nodded with satisfaction. This is actually a question that is not difficult to guess, if it weren't for Ye Hua being too impatient and losing the ability to think calmly, he could have thought of this layer at all. As Sukhoi said, there are so many keys in the safe, in order to consume their time, in order to maximize this effect, the key corresponding to the keyhole should be the one with the highest proportion of all keys.

In other words, it is the "mass style" that they are most troublesome to compare with. These keys, commonly found in a variety of spring-loaded locks, are unremarkable and have no high-tech component, but at this point, the subtle differences in the serrations of these keys will directly determine their fate.

But as I saw just now, there are the largest number of these keys, and it may not be easy to find the special one among them. As soon as they thought of this, the faces of the people who had just narrowed down because they had found the keyhole suddenly darkened again.

"Get all the keys together!" Xiang Nanxing suddenly said loudly, "Even if it is a popular style, it is different in terms of specific shapes, so let's separate them according to their appearance first!" ”

"No, it's too late...... Sukhoi said dejectedly, "even if one person is in charge of a bunch of them, it's still too much work." Under normal circumstances, a key needs to be matched about half to find a pair, and in the worst case, it is even necessary to compare all of them, where do we have so much time. ”

"No, as long as we don't make mistakes when sorting out the styles, we don't need to compare!" Xiang Nanxing said categorically, "Do you remember that prompt? Sole! The key that can be inserted into this keyhole is the only one! ”

Seeing that the other people still looked incomprehensible, Xiang Nanxing grabbed his hair anxiously, and finally found the most direct expression from the chaotic thoughts.

"Just count! After sorting the piles according to the style, the pile containing the unique key must be an odd number, because there is no second key to pair with it! ”

"That's right!"

Sukhoi suddenly realized, and then Ye Hua and Chris. Without further ado, Xiang Nanxing had already run to the key pile when he spoke, and began to take out those popular style keys alone, and then sorted them according to their color, texture, shape and other characteristics, Sukhoi and Chris also followed Xiang Nanxing's example to pick the key, while Ye Hua put his hand into the safe, ready to take out the remaining keys inside.

However, I could see that he was really impatient. The keys bite each other in the box, it is not easy to dig, Ye Hua is more and more laborious, suddenly ruthless, stood up and grabbed the safe, and shook it up and down like crazy.

The keys clanged to the ground like raindrops, Xiang Nanxing subconsciously covered his face with his hands, while Sukhoi opened his mouth to scold him. However, as soon as he turned his head, his wide open mouth suddenly couldn't close. He looked at somewhere at Ye Hua's feet in a daze, and he didn't know what to say for a while.

And Xiang Nanxing also saw it.

What is it? He and Sukhoi glanced at each other, and each saw the confused look on the other's face. Before they could sort the keys, the safe was full of things and they couldn't move it, so they couldn't find out what was going on behind it. At this time, as Ye Hua lifted the safe, the wall that was originally close to the safe was also exposed, and there was a hole there!

Looking over from this side, the cave was dark, as if it led to a deep place, but Xiang Nanxing remembered that if a hole was opened from this direction, it should also lead to the outside.

Although he was not calm enough, after all, he was at his feet, and Ye Hua finally saw it. He slowly lowered the safe, then carefully reached into the hole. "Click", he seemed to push some mechanism, the light penetrated through the dark edge, Ye Hua leaned forward, and the bright light overflowed from the hole and spilled into the room.

"It's a hole to the outside!" He excitedly announced loudly, "You can get out here!" ”

Now that Ye Hua had tried it, the other people were relieved to approach and take a closer look at the small hole. The thing he pushed away was actually a small baffle-like mechanism, fixed with a few springs, and could be pushed up with a little force, usually the baffle blocked the light so it looked dark, but from the point that the light could be seen after pushing it open, this hole was indeed as Xiang Nanxing speculated, and it was to the outside world.

The fly in the ointment is that this hole is really small, Xiang Nanxing tried it, and he was afraid that he would pass it reluctantly, and nine times out of ten he would be stuck in the middle, so Chris, who had a small skeleton, was sure to pass. The tall and thin Ye Hua may also be able to give it a try.

It was like a basin of cold water poured on his head, drenching him to the core.

Sukhoi was also silent, and he stood with his hands folded and looked at the small hole, as if he was making a similar estimate in his head. In terms of physique, he was a little wider than Xiang Nanxing's shoulders, the latter was reluctant, he was afraid that he wouldn't even be able to go in. At this time, looking at the excited Ye Hua and the obviously eager Chris, Sukhoi hesitated for a moment, and finally said: "I think this matter still needs to be observed again, safety first." ”

Chris looked up at him in bewilderment. Although he was in a hurry to get out, Chris had always been convinced by Sukhoi's judgment, and since he said that he wanted to observe, he might as well listen to the reasons first.

"There are two reasons for this." "First, it's too easy to climb this hole and get out, and it's something that isn't mentioned in the rules, and it's not sure if it can actually get to the outside world, or if it's just a trap," Sukhoi explained. And the second one, we've just figured out how to solve the key puzzle, which is the right way to play the strategy game, and I think we should try this first. As for this hole, in fact, the time is completely sufficient, and if the work of picking the keys really can't catch up, it's not too late for you to try this again. ”

His words are reasonable, especially the last point is the key - since it is the same at all times, why not take the right path first, and then come back when it can't get through? So Chris thought about it and accepted it. The boy didn't drag his feet either, and immediately walked back to where he was, and continued to devote himself to the huge work of picking up the keys.

Ye Hua also agreed, after pouring the key, he naturally turned to the picking work at this time, but the moment he turned around and walked towards the pile of keys, Xiang Nanxing suddenly noticed that his gaze was unnatural.

He was looking at the little hole at the foot of the wall, his eyes flickering.
