This passage was much better than the one that went down last night, and it was obvious that Lin Feng had built it according to the standards of a safe passage. At the beginning, there is a small section that is downward, and then it tends to be horizontal, indicating that in order to avoid the underground part of the rockery, it can also give a good buffer to the exit.

Lin Feng turned off his flashlight, because a small light bulb would appear every ten meters or so in this section, and for convenience, the light was still voice-controlled.

Wu Yuran couldn't help but mock: "You are building a bomb shelter here!" Are you worried that one day there will be no place to hide in the war, so you will take your whole family to hide in this place? ”

Lin Feng smiled: "I have this plan, but this place is only about five meters from the ground, and it is a bit unqualified to be an air-raid shelter." But it's a good place for us to date, and few people here know about it anyway, so I'll get a bed over when I go back! ”

As he spoke, Lin Feng didn't forget to throw a wink at Wu Yu, if Wu Yu didn't know that he was a gentleman, maybe this flattering look would really make Wu Yu fall.

Shaking his head, Wu Yu found that Lin Feng was not easy to mess with, so he simply changed the topic and said, "Where does this passage connect?" Is that the same passage we went down last night? ”

Lin Feng shook his head: "No, I can't be sure where the exit is." ”

Wu Yu rolled his eyes: "Are you teasing me?" You spend money to find someone to dig the passage, can you not know where the exit is? ”

Lin Feng shrugged innocently: "The exits are five parallel passages, all of which were designed by professionals I hired. Yu Chen made a relatively large-scale yin and yang array inside to provide power for the exit. So we don't necessarily get in from which of the five exits, and we can't be sure where we get out. But fortunately, I walked through all five exits, but it was just a matter of walking more and walking less, and it was not a big deal. ”

Seeing Lin Feng walking forward calmly, Wu Yu couldn't wait to step forward and slap him twice, but seeing Lin Feng's graceful figure from behind, Wu Yu was actually a little unbearable.

After thinking about it, Wu Yu asked, "What does it mean to be brought in by the exit?" Is it said that the mouth is alive? You don't have a python under here, do you? Let's get in from the python's mouth and be slapped out of it as poop to another exit? ”

Lin Feng frowned and said, "Brother-in-law, have you watched too many cartoons?" Or did you read too many novels? How disgusting, you actually thought of it, I'm not as heavy as you. ”

Wu Yu also knew that what he said was a bit too, so he smiled: "Then you just tell me directly, always let me guess something!" My imagination is very rich, if you don't tell me, I must be thinking in a bad direction! ”

Lin Feng said helplessly: "It's actually very simple, do you know the revolver?" ”

Wu Yu nodded: "You know, what's wrong?" ”

Lin Feng stretched out his slender fingers, stroked the rootless fingers in a parallel way, and then said, "The passage we are in is the muzzle of the gun, and the exit is a wheel. The wheel will start moving because of the force, which will take us to the next exit. It just so happens that I've set up five sets of these wheels here, which means that our exits will be five different places. ”

Wu Yu looked at Lin Feng's fingers, trying to build a rough model in his mind. According to Lin Feng's description, the passage he is in is composed of five different wheels, so there must still be parallel passages on his upper and lower sides, but only the traces can be seen in the node places.

After thinking about it, Wu Yu found some questions that were not quite in line with the truth, looked at Lin Feng and asked, "That's not right!" Five sets of such wheels should have twenty-five different exits! How could there be only five? ”

Lin Feng smiled: "There is not so much power, the formation provided by Yu Chen can only provide part of the power, and the rest of the things come from the people who enter the passage." Everyone who enters the passage will work on the bottom of the passage, and it just so happens that I have brought back some machines abroad that can be converted into power. At the same time, this is also the best defense tool, if it is not for our people to enter this channel, then repeatedly walking back and forth this channel, will be repeatedly carried by the wheel to different places, and when the power part reaches a peak, that is to say, someone in a period of time, repeatedly walk this channel three times. The passage will freeze on its own, and the wheel will turn to a place where there is no exit, and both ends will be sealed, trapping people in it. ”

While talking about Lin Feng, he used his fingers to draw Wu Yu, roughly describing the basic principle of the entire passage, and Wu Yu also roughly saw what kind of structure it was.

However, when Wu Yu heard that the passage was stuck, he first looked around nervously, and then marveled at Lin Feng's design ideas and the money needed to build such a passage.

Wu Yu thought of a question, and asked again: "Then you don't need five wheels at all!" Isn't it possible to achieve such an effect with a runner that uses the dislocation of the upper and lower passages? ”

Lin Feng seemed to have guessed Wu Yu's thoughts, and said with a smile: "That's too simple, I considered the method you said when I designed this place, but in order to achieve an effective blockade." In the end, five reels were chosen, and like you said, there are twenty-five different combinations of five reels. Because there are only five exits, the other twenty are locked exits, that is, there are no exits at all. Another contingency is the speed of travel on this passage, if it exceeds our pre-designed speed, the people inside will also be taken by the runner to the locked exit. Therefore, we must not go too fast through the five wheels, and try to keep the time difference between the five wheels to no more than one minute, otherwise we will be locked up. ”

At this moment, Wu Yu was completely stunned, such a design that Lin Feng said, if it appeared in the underground vault of a certain country, he would be willing to believe it, but if it appeared in the school, how much money would the Lin family have to spend to build it!

Seeing Wu Yu's stunned expression, Lin Feng said proudly: "Actually, the initial part of this passage is already like this, we have just modernized and improved it on this basis. Sensors, power supplies, pedometers and other things, and then there is power source recovery. The resentful spirits we unintentionally released, later analyzed by Yu Chen, were the power source of this channel. ”

Wu Yu began to be blindfolded, stared at Lin Feng through gritted teeth and asked, "Can you tell the truth, didn't you just say that you found someone to dig this passage?" Why has it become your improvement now, which sentence is true and which sentence is false? ”

Lin Feng smiled: "It's all true, I asked someone to dig up here under the statue in front." Inside is the part of the wheel, which I improved. The original wheel passage led to another place, but that place was buried due to the expansion of the school. So I had to reconnect the passage here to get to where we wanted to go as quickly as possible. ”

As soon as Lin Feng said this, Wu Yu noticed the road under his feet, and sure enough, starting from here, although the passage originally built by the stone slab was also a stone slab here, it was obvious that the stone slab on this side had obvious traces of reconstruction, and it should obviously be the place where Lin Feng had improved.

Wu Yu didn't dare to walk in, although Lin Feng explained the principle of the wheel in front, but Wu Yu still didn't believe in the authenticity of this thing, and before there was a conclusion, Wu Yu still didn't plan to separate from Lin Feng.

Lin Feng took out his mobile phone, Wu Yu was a little strange, he didn't know her tight-fitting dress, where the mobile phone was hidden before, and the flashlight.

Seeing Wu Yu looking at him curiously, Lin Feng said calmly: "Brother-in-law, don't waste your brain cells on me, it's easy to crash, and it's not easy to restart when the time comes." Let's go together, don't be too fast, don't be too nervous, the first wheel will be fine. Both wheels are the same, the first wheel is used to calculate the speed and time of your steps, and the second wheel is used for synchronization, if there is a significant gap with the first, when it comes to the third wheel, it will take you to the corresponding exit, or a blocked channel. ”

Wu Yu nodded, seeing that Lin Feng's mobile phone screen was displaying a stopwatch, obviously Lin Feng was not lying. This stopwatch should be used to calculate the time to walk a wheel, and it should be fine to follow Lin Feng.

Lin Feng seemed to feel that his words made Wu Yu very nervous, Lin Feng didn't care and started walking directly, saying as he walked: "Brother-in-law, let's go!" It's not that serious.,If I can renovate here.,I'll definitely leave a bug for myself.,Haven't you played the game? Any game designer will always leave a bug for himself, which is convenient for brushing equipment. ”

Wu Yu was stunned for a moment, but he immediately followed, and when he heard Lin Feng's words as he walked, Wu Yu breathed a sigh of relief in his heart.

That's true, any game designer will leave a bug for himself, in order to better debug the game, and if necessary, he can get out of it. There was no need for Lin Feng to lie to him, because Lin Feng was not sure who was trapped in it, so there would definitely be a way to untie it.

Lin Feng continued: "Brother-in-law, if I didn't take you on this road, I would have usually run over. The total length of the five reels is only about 100 meters, and I can basically leave the remaining four reels before the reel spins. So I can only teach you this time, and next time I'll run with you. ”

Wu Yu was stunned, a little didn't understand what Lin Feng meant, and at this moment, he happened to walk to a short section of a different stone slab, Wu Yu was in a daze, Lin Feng suddenly accelerated and ran forward.

Wu Yu hurriedly accelerated, but found that his speed could not reach Lin Feng's speed at all, and in the blink of an eye, Lin Feng appeared at the node of the next wheel. Wu Yu secretly screamed in his heart, and was about to chase hard, but suddenly he only felt that the passage he was in was shaking, and he saw that where Lin Feng was, the passage was slowly sinking, and obviously the wheel that Lin Feng said began to operate.
