The situation in front of him is extremely complicated, Niu Erzhu does not dare to act rashly, if he makes a mistake and takes a wrong step, the consequences are unimaginable, but he can't just stay still, when can he go out? Da Shao groaned for a while, suddenly got up, and walked back, he thought in his heart and understood, since this road is not passable, it is better to return the same way, although the front is also unable to get out, so I can see the outside, I came in a hurry, carefully groped for a while, maybe I can find another way out!

Da Shao thought very well, but just after turning around and walking a few steps, he couldn't go on, there were still two roads in front of him, the same as behind him, two passages, two holes, exactly the same, no matter in terms of size, shape or height, there was no difference! Da Shao was dumbfounded, this time the back road was blocked, the front road was blocked, and he was trapped in the same place! Niu Erzhu was in a dilemma, so he could only stare at the spot.

Although Niu Erzhu had nowhere to go, he was still quite sober in his mind, staring at these two holes for a long time, and his heart suddenly moved, this is not right! There are a lot of similar things in the world, but there are no exactly the same ones at all, you are two bricks carved out of a mold, so there is a difference, the hole in front of you is completely consistent, obviously illogical. Niu Erzhu looked at it for a long time, and suddenly smiled, if the two passages are exactly the same, it can only mean one problem, or one of the holes is fake, or both holes are fake!

Da Shao figured out this matter, and immediately had a plan in his heart, no need to ask, this ghost with a regular yellow skin, what he saw in his eyes was not real, maybe it was a thoroughfare in front of him, maybe he was still in the tunnel, but there was only one passage. But although this thing has been figured out, the problem has not been solved, although it is an illusion in front of you, but which road is true and which road is fake, but it is impossible to distinguish at all.

Da Shao sweated down, even though he was usually quick-witted, he was a little at a loss at this time. Da Shao was so anxious that he turned around in a circle, and there was nothing to do, and suddenly there was a change behind him, in this boundless darkness, suddenly from behind Niu Erzhu came a series of clear "drip" sounds, this time Da Shao was unprepared, his body trembled, and he hurriedly turned back, but saw that in the darkness behind him, there seemed to be a light faintly, and there seemed to be a figure flashing in the light, like a ghost, fleeting, and disappearing in one of the passages in a blink of an eye.

Da Shao was shocked, and couldn't help scolding: "His grandmother's, but what is the blame, this place is really evil." Before the words fell, the voice suddenly disappeared, Niu Erzhu put up his ears and listened for a long time, the passage was silent, and he regained his calm again, Da Shao scolded in his mouth, waited for a long time, and there was still no movement, Niu Erzhu did not want to make extraneous branches, turned his head and observed the two channels in front of him again, but as soon as he turned around, the voice sounded behind him again, not much different from the last time, but it was more urgent, more complicated than the previous voice, and there was a sense of impatience in the constant thinking, as if urging something.

In the passage where you can't see your fingers, the sudden sound breaks the death-like silence, like a drum hammer, constantly beating in Niu Erzhu's heart, and the noisy and frequent percussion sound is particularly clear in the passage, mixed with the unusually quiet environment around it, giving people a feeling of heartbeat. Niu Erzhu simply did not move, stood in place and listened several times, and found that although the sound was noisy, it was not irregular, knocked three times, stopped, and then three times, over and over again, over and over again. It's as if someone is hiding in the dark, and they are giving themselves some code through the sound of tapping.

Niu Erzhu's heart moved, the people of the rivers and lakes lived a day of licking blood with a knife, and it was inevitable that they would encounter various dangers, in order to protect themselves, they gradually explored a set of means to ask for help in the predicament, including various signals sent by smoke, footprints and lights, but the most commonly used is a variety of sounds, because the sound penetration is strong, and the means of smoke, footprints and lights are limited by the terrain, wind direction and other problems, and sometimes they are not useful at all. Niu Erzhu is the most old Jianghu, nothing else can be, but these life-saving things can't be not, because this is related to his own life!

Niu Erzhu listened carefully, this repeated percussion sound seemed to hide some rules, three sounds and one stop, and these three sounds were of different lengths, the middle one was slightly shorter, and the other two were longer. Da Shao is most familiar with this kind of voice, and after listening to it for a while, his heart suddenly lit up, isn't this exactly the code commonly used by people in the rivers and lakes? So repeatedly, tirelessly, in fact, there is only one meaning: immediately move closer to me, there is danger ahead! The sound was loud, but it was a little dull, as if someone was hitting something soft with something hard.

Niu Erzhu hesitated again, since he entered this place where he couldn't see his five fingers, all kinds of situations were unimaginably complicated, and now this voice may be someone who saw that he was in deep trouble and rescued himself in this way. However, it may also be a trap for the yellow skin, which will put you in greater trouble, and whether to go over or not is a difficult choice. Niu Erzhu couldn't make up his mind for a while, and he didn't know what to do in place, but the voice was getting more and more urgent, as if there was no sign of stopping, one after another, constantly urging Da Shao.

Niu Erzhu is sitting in a fierce ideological struggle in his heart, will it pass or not? In the past, I would have been in a situation where I might have had a huge album, but it could have been even more dangerous. However, although they are still trapped here, there is no further danger. Niu Erzhu was in a dilemma, hesitated for a long time, and suddenly bit his teeth, that's it, you can't do it if you are timid, you just have made up your mind and don't move, you can't stand it for a long time, and in the end you have to be trapped here, but if you are lucky, because this voice escapes from the ascension, then everyone will be happy, even if there is any danger ahead, it is a big deal, and the result is the same as being trapped in place, but one is happy, and the other is zero guilt.

Niu Erzhu made up his mind, raised his legs and left, and followed the sound all the way over. The sound had not stopped since it sounded, but perhaps because it was too close in the passage, it sounded ethereal, unreal, and seemed to be present in all directions. Niu Erzhu walked as he carefully identified the source of the sound, walking around, getting closer and closer to the sound, but the bottom of Da Shao's heart became colder and colder, because he found that the voice did not seem to be in front, nor in the left and right surroundings, but underground! There was a faint vibration on the muddy ground, as if something in the Netherworld was waiting for Dashao's visit! r1148
