Keep moving?

Nangong Yundie thought for a while before she reacted, Xiang Nanxing was originally talking about things on the other side of the door. Genius remembers the first three or five in a second

Indeed, I couldn't hear the sound from that side from the beginning. The two had been talking before, but shortly after the conversation ended, they heard some small grinding noises, and then there was silence. According to common sense, the friction sound should be the man on the other side of the door trying to open the door, and then the silent state, either he opened the door and left, not in the room, or he entered the state of the old monk in a state of concentration, and the whole person did not move, so there was no movement at all.

Compared to the latter case, it is clearly the former that is more logical.

But how did he do it? On your own? Nangong Yundie couldn't help but wonder, "Even if the two cooperate, they have to gamble on speed to be able to do it, how did he open the door in front of the other party?" ”

Xiang Nanxing smiled, walked to the corner of the passage and picked up a wire, and began to roll it up in his hand.

"How ...... way"

He wrapped one end of the wire around the top valve, and said slowly, "That guy said something before, it's quite interesting." 'If you think of this as a trial game'...... Hehe, if this is really a trial game, then it must be the lowest difficulty, and the host in charge is at most the trainee level. ”

"Host?" Nangong Yundie was a childlike after all, and was immediately attracted by the fresh words in his words.

"That's not the point." Xiang Nanxing smiled, "I want to say, it's much simpler than you think." ”

At this time, Xiang Nanxing had already tied one end of the wire tightly to one of the valves, and twisted the other end into the shape of a hook with force, which could be fixed with just a hard pinch. Nangong Yundie frowned and looked at the movements of his hands, a little wanting to ask him what he was doing, but he was afraid that it would become a disturbance again.

"You said that guy took advantage of the first shot, which is reasonable. But since that guy has pried the door open a little bit to observe the mechanism, he is aiming for more than just such a small advantage, and he will definitely find out what I can see. Xiang Nanxing pointed to the corner of the putter that was faintly exposed in the crack of the door, and said slowly, "He looked carefully to find that key 'point', and now it turns out that he did find it." ”

"The key point?"

"That's what I'm just looking for." "That's the 'location' where the alarm was triggered. ”

Nangong Yundie was slightly stunned, and then exclaimed "ah", and suddenly realized.

"The location of the metal cordon is not directly behind the deadbolt, because then the vibration caused by the daily opening and closing of the door may affect it, and once the vibration is directly locked, it is troublesome. As you can see, I turned the first valve a few times, but nothing happened, and I didn't react until I turned the second valve one more turn than the previous one, which means that the trigger position is in this position. Until then, no matter how much I tossed the valve, the alarm wouldn't go off. "So in the final analysis, there is a fatal blind spot in this design, which can be cracked as long as you see it." ”

"The solution is ...... Don't go from 'off' to 'on', but from 'half-open' to 'on'. Xiang Nanxing smiled slightly, "The direction of the three valves is the same, it will be very smooth to turn one and then the next, and it will be looser to start in the state of turning a few times than starting from zero." The difficulty has been reduced so much that even one person can complete it quickly. ”

"Yes!"

Nangong Yundie was so excited that she almost jumped up with joy. Compared with those adults who are accustomed to seeing the world, children like her are obviously much more direct in expressing their feelings, Xiang Nanxing's idea of breaking the game is something she hadn't thought of before, and at this time, once it is broken, she suddenly feels enlightened, and this scene makes her feel excited just thinking about it.

It's just that in addition to being excited, she inevitably changed her surprised gaze to look at the man in front of her. He found the flaws in the design that she felt was impeccable, as if he had already gone through countless tests in this area.

This "uncle" is really as great as the legend.

"So without further ado, let's get started now?"

She saw that Xiang Nanxing was already turning the valve and preparing to try it for the second time, so she couldn't help but be eager to try. "Why don't you let me come first this time?" "It doesn't matter how many times you try this anyway, you can't see the mystery on the other side." ”

"No, I want to try to get it right the first time, and now the time is still very short." Xiang Nanxing carefully turned the valve, controlling where it stayed, and then began to turn the second one. The upper valve is tied to the wire and droops down, and it goes around the root of the valve in the middle, which also looks special.

And Xiang Nanxing's gaze stayed on it for an additional moment.

"But then again, there's something for you to do." He said, "It's not a one-time success, but if it can be done successfully, it's fun." ”

"Tell me!" Nangong Yundie suddenly became interested.

Xiang Nanxing looked at her excited appearance, and secretly sighed that the Nangong family was really a lot of weirdos. This little girl obviously found that there was a chance to return to the target, and knew that most of the danger of violating the law was eliminated, and as soon as this big stone fell to the ground, the whole person relaxed and revealed her true nature. Although she was in danger and was walking with an unfamiliar person, she didn't do it properly, like an outing.

With such an open-mindedness, Xiang Nanxing can only bow down. Also impressed him was Nangong Asoqi's character of freely switching between madness and calmness, as well as Nangong Jingzhi's low-key and tough personality that seemed to be hidden in the fog. In contrast, although Nangong Qian's temperament of being cold on the outside and hot on the inside is a little awkward, it is already a very normal person's performance.

Thinking of Nangong Qian, his heart moved again. What is she doing outside at this point? Knowing that the house was invaded, the owner should have taken measures, would he call for rescue, or would he just let the security guard expand the scope and search out? If so, is Xiaoqian's hiding place safe, and will she take risks because she is worried about the situation below?

Many doubts filled Xiang Nanxing's mind for a moment, and he didn't come back to his senses until Nangong Yundie called him a few times "uncle" one after another.

"Talk about it, talk about it." Nangong Yundie looked very excited.

"Okay." Xiang Nanxing smiled bitterly and put these helpless thoughts aside for the time being, "If you just open it, it is enough to know what you just did." But there's so much more we can see. As you can see, after the alarm is triggered and the other party presses the button to start the motor, the three valves are not locked synchronously. I haven't touched the top valve yet, so it didn't move from beginning to end during the locking process, and the middle one I fought with it for a while, so it turned slowly, and the bottom one returned to its place soon after the motor started. ”

"In other words, their respective actuators are powered by the same motor, but they operate separately."

"Does that make any sense?" Nangong Yundie was puzzled, "This thing is normal, if it is synchronized, the valves that have not been turned will be tightened together, and it will be easily damaged." What's so special about this? ”

Xiang Nanxing nodded. "Nothing special, logically it should be." "But there's a fun way to play behind this simple fact, so we can do something about the door and make the person who controls the button feel bothered." ”

As he spoke, he turned the third valve to the point where it was about to touch the line. According to the theory he had expounded before, it was obvious that he should start to open the door next, but at this moment, Xiang Nanxing's movements stopped.

He bypassed the entangled wire through the valve in the middle, and handed the end in his hand to Nangong Yundie.

"This task is up to you. Remember, it doesn't matter if it doesn't work out, it's a big deal to try again, the key is to be careful not to get your hands and feet stuck in the crack of the door, as that will hurt. "I'll open three valves in a row, open enough to get through, and then pull the third valve for a few seconds." You take this opportunity to put the wire on the valve, tie it up, and we'll go in again. ”

"That's it? And after that? Nangong Yundie looked at the wire wrapped in a strange shape in a daze, she didn't understand what it was going to do.

"Let's watch the show after that." Xiang Nanxing blinked, "Okay, don't gossip, get ready...... Begin! ”

He seemed to have a full clockwork, and his hand speed began to turn from the top valve quickly, and Nangong Yundie at the bottom was holding the wire in his hand, his shoulders were stiff, and he was staring at his movements nervously.

The first one opened, but in the blink of an eye. Sure enough, this organ is just like Xiang Nanxing said, for various reasons, the gap between starting from the middle and starting from scratch is more than half of the time.

And then the second, still fast. Xiang Nanxing's hand speed did not slow down in the slightest during this process, but Nangong Yundie knew that at this point in time, the alarm on the console had sounded. The other party may press the button at any time to start the motor.

Next, it's time to compete in reflexes and speed.

Xiang Nanxing's hand continued to move downward, and the third valve, the speed at which he rotated was actually faster! In front of the frightened Nangong Yundie, the third valve of this door was finally opened, and the whole door seemed to have unloaded all the burdens, and with a strong pull by Xiang Nanxing, it opened more than half.

However, at this moment, Xiang Nanxing's face changed, showing a look of difficulty.

The door that had been halfway open suddenly stopped, and then slowly closed again, as if pulled back by an invisible hand. Xiang Nanxing's feet were firmly pressed against the floor and door frames, but it was not enough to stop the momentum. The two valves above and in the middle have all quickly returned to their positions, only the bottom one was pulled by Xiang Nanxing, and for the time being, it was just moving back little by little.

However, his arms were already green, and he would soon be unable to support them.

"Quick!"

He moved his feet toward the side of the door, barely squeezing a word out between his teeth.

Nangong Yundie suddenly came back to her senses, put the hook of the wire in her hand to the valve, and then quickly twisted it a few times, wrapping it tightly!

At the same time, Xiang Nanxing's overwhelmed hands and feet finally couldn't keep their original posture! As soon as he let go of his hand, the valve on this side turned rapidly, and it seemed that the whole door was about to close at a flying speed!

Can they seize the fleeting opportunity?

At this moment, a confident smile appeared on the corner of Xiang Nanxing's mouth.
