Qin Shiyin held Jin Muxuan's arm and said softly, "Mu Xuan, be careful." ”

"Ha, Shiyin, don't worry, I've always been blessed with a great fate, and when I go down and figure out the situation, you can come down again." Jin Muxuan was a little happy when he heard Qin Shiyin in front of everyone for the first time, showing his initiative.

Hearing this, the silver chief checked the rope once, and confirmed that there was no problem, so he patted Jin Muxuan's shoulder, and the rope of nearly three hundred meters was placed on the ground, which was very heavy, and three soldiers came over on the side to help pull the tail of the rope.

Everything is ready, Jin Muxuan looked at the deep circular passage, climbed down carefully from the side, touched the wall of the passage with his hand, and found that the wall of the passage was unusually smooth, and after three meters inside, he couldn't see the situation inside, took out the wolf's eye flashlight and looked forward, and found that there was a turning in front of him, no wonder he couldn't see the situation below.

Cautiously walked down, suddenly, Jin Muxuan's feet slipped, and the whole person slid towards the front and slid along the front, under the inertial sprint, Jin Muxuan couldn't stop, because after the passage turned, he was stunned to find that this channel was a channel similar to a ∞-shaped infinite loop, and he was dizzy.

"Boom"

At this time, there was some water flow in the passage, which made Jin Muxuan feel like he was playing rapids, extremely exciting, extremely fast, pulling the rope and falling quickly.

"Dizzy!! God, bless the people above, find out quickly, or I don't know where I'm going to go. Jin Muxuan shouted helplessly, he would not have come down if he had known, this is simply a pit that does not pay for his life.

Of course, the abnormality was naturally found above, and the rope suddenly pulled into it quickly, and it was known that Jin Muxuan was at a rapidly falling speed.

Qin Shiyin had been paying attention from the beginning, and when she saw that the speed of this fall was too fast, she immediately asked everyone to help pull it and shout at the entrance of the cave: "Mu Xuan, Mu Xuan!" Can you hear me? ”

All this was found in a moment, Jin Muxuan was already at this moment, and he had already followed the ∞-shaped waveway, falling quickly for nearly fifty meters, but fortunately, at this time, the people above grabbed him, and Jin Muxuan hoped that he could hear Qin Shiyin's shout.

Immediately told Qin Shiyin loudly about the situation inside, Qin Shiyin didn't expect that in this deep passage, it turned out to be ∞, but he was afraid that Jin Muxuan would not be able to contact him if he went deeper.

Thinking of this, he asked Jin Muxuan to slow down at the moment, and the distance of the rope falling ten meters per minute was lowered, and by the way, he asked Jin Muxuan if he understood the telegram code, Jin Muxuan thought about it when he heard it, and then understood Qin Shiyin's thoughts.

If you go down a little more, because the channel is ∞, then your voice is likely to be blocked and cannot be transmitted again, and the ∞ shape has a serious weakening characteristic of sound wave transmission.

In the case of the telegram password, you only need to pull the rope and report the following simple situation with the number of times, and you should still be able to do it, of course, provided that the rope of these three hundred meters is enough.

"Shiyin, I see!"

Qin Shiyin heard the voice from Jin Muxuan below, and waved his hand to the warrior behind him, signaling to slow down the speed of the descent

Jin Muxuan slowly fell down, but he sadly found that because it was a ∞ shape, this pause, in the front of the upward channel, there was no inertia of the sprint, and he was stuck in the channel, unable to advance or retreat.

Fortunately, it was already possible to use the telegraph password as a report, and began to pull the rope frequently the number of times, and the warriors above immediately found out.

"Command, there is a situation, the number of the return order of the rope is five, eleven, six, twenty-two"

Qin Shiyin immediately took out a notebook and began to write it down, and then began to sort and decode, and finally found the problem, Jin Muxuan was trapped, and the falling distance at this time was seventy meters, this passage was too weird.

The first time he entered the passage ended in failure, Qin Shiyin sighed and said, "Let's get him out first." ”

Jin Muxuan felt the force coming from his waist, knowing that the person above was pulling him up, he shook his head helplessly, and after waiting for five minutes, Jin Muxuan was finally rescued from the passage.

Qin Shiyin immediately cared: "Mu Xuan, are you okay?" ”

Jin Muxuan shook his head and signaled that it was okay, and immediately told everyone about the situation in the passage, and everyone couldn't imagine that this would be such a peculiar passage, and the construction of this kind of passage in the ∞ shape is quite a big project, and the more so, the more curious people are about the situation below.

Only Yin Dingjing listened to the worry on his face, looked at Jin Muxuan, and began to say the concerns in his heart, that is, this ∞-shaped passage may correspond to the reincarnation disk, and the totem of the snake's head biting the snake's tail is likely to be a hint, but I am afraid that at the end of the passage, there is a deadly mechanism waiting for everyone.

Hearing this, everyone's faces changed, if this was the case, it would be too dangerous for Jin Muxuan to go down alone just now.

Qigong said with some confusion: "What should I do, could it be that a ∞-shaped passage blocks everyone who wants to go down?" ”

Jin Muxuan was also aroused at this time, the more so the more brave he became, although he wanted to go down again, but he began to think about the design, how he should go down, it was the safest way.

After a stick of incense, Jin Muxuan finally thought of a way, with the characteristics of the ∞-shaped channel, he found a more unique way to move forward, that is, during the descent process, the rope should not be tightened, and he could follow the inertia, slide to the ∞-shaped rising channel at a time, and then hold the rope tightly in this position.

After observing for yourself, you can send the message in the form of a telegram cipher, and you can move on, and if there is a situation, you can also detect and stop it early.

After hearing Jin Muxuan's words, Qin Shiyin nodded, and began to let Jin Muxuan recall and calculate the distance between the descent and the ascent of the rope in the ∞-shaped passage, so that the soldiers could mark the rope to avoid mistakes, which was related to human life, and she naturally did not dare to slack off.

Jin Muxuan thought about it, this ∞-shaped descent should be five meters, the corresponding sprint to the rising position should be five meters, and the front and back should be ten meters, the ∞-shaped passage is so difficult to build, I believe that when it is built, there should be a certain fixed value.

With a conclusion, he immediately asked people to mark the rope with a point of ten meters, and then Qin Shiyin looked at Jin Muxuan: "Mu Xuan, if there is really the danger that Senior Yin said below, you will have nothing to return as soon as you find out." ”

"Well, I know, don't worry, now we finally understand the general situation below, in the ∞-shaped passage, I believe it won't be in such a hurry as just now." Smiling at Qin Shiyin, Jin Muxuan wrapped the rope around his waist again, ready to fall again.

This time the descent was much smoother, and every time he slid to the place where the ∞ was rising, he would pause, so that Jin Muxuan would have time to observe the situation in the next section of the passage.

At this time, the water flow in the channel continued to appear, and the color of the water appeared a little yellowish under the irradiation of the flashlight, but fortunately, the amount of water was very small, and it would not wash people out, and it seemed to be river water from the water quality.

"It's strange, how can there be a river here, it's too weird, there is Shuangxi Lake above, and there is a spring on one side, it's too weird." Theoretically speaking, Jin Muxuan thought that it was really impossible for the river, river, and groundwater to converge together, but now it was a coincidence, because he had discovered such a place at this moment.

Continue to slide inside, about two hundred meters, it seems that at the end of the passage, there is a fork, where Jin Muxuan can actually hear, the sound of the violent water coming from outside, it seems to be like the sound of the huge waterfall.

Seeing the passages on the left and right, and finding that there was light faintly transmitting in, Jin Muxuan thought for a while, thinking that this one was a ∧-shaped exit, and his current position should be at the top of the position.

"Is this playing with me, in the end, there will be a fork in the road, should there be an exit is dangerous, and an exit is safe, that would be too bloody." Jin Muxuan muttered to himself.

After a slight pause, Jin Muxuan sent a password through the rope to contact Qin Shiyin, but there was no movement to send it back, only to know that he had entered too deep, and his strength was no longer enough to send the telegram password, because the weight of the two-hundred-meter rope that extended in was no longer something that Jin Muxuan could pull alone.

I'm afraid that after a minute, the people above who don't know will definitely extend the rope to a distance of ten meters, and in desperation, Jin Muxuan can only face the choice of exit at this time, looking at the fork in front of him, Jin Muxuan looked left and right, and finally chose the exit on the right.
