The big pit, poof, did not cause much ripples, and Liu Yuan and the others were also gone, the pit was still a pit, and within this huge underground rift, it did not change because of their disappearance. Outside the dark green tent, Professor Gao quietly looked at the direction of the vortex, his expression unchanged, not knowing what he was thinking, but under the cliff of the lettering, the busyness of a group of people did not make him pay too much attention. "Professor, Professor! There is a case! I don't know how long later, near the empty tent field, there was a cry of joy, and the loud noise of the vortex could not hide its excitement.

Sitting alone on the bluestone platform, looking at the scenery at ease, Professor Gao seemed to be in this mood at this time, the fatigue of many days seemed insignificant now, hearing the shout, it seemed to be expected, not surprised, smiled lightly, stood up, and walked out. On the other hand, Liu Yuan and the others were not so comfortable, the huge tearing force of the vortex almost wanted to make him collapse, holding the copper ball in his arms, staying with each other, and he didn't know how much water was poured into his mouth and nose, and he couldn't make a sound, on the other hand, Zhang Erhe was much better than him, covering his nose with one hand, closing his eyes tightly, and his body fell straight down, just a few dozen seconds, but it made them feel like they were living like a year.

With another pop, the two of them finally fell out of the whirlpool, and there was no light in front of them, but they could also feel that they were in the water, cold and biting, and shivering. Liu Yuan slowed down for a while, the wanton impact of the water just now made him extremely uncomfortable, and his nose was still dripping with water, looking quite embarrassed. "Zhang, Zhang, Uncle Zhang, first, first ashore." Liu Yuan said tremblingly, hugging the copper ball tightly, groping around, but the imaginary river bank did not appear, there were stone walls on both sides of the river, and there was not even a place to stay. "Yuan'er, give me the copper ball first, you can look around, and find a place to dry your clothes first." Second Brother Zhang said with concern, it is completely dark about the situation here, and this place is indeed completely shady.

Now he can only do it according to Zhang Erhe's method, hand over the copper ball to him, and spew out a mouthful of evil water, holding the wall with both hands, chanting words in his mouth, and the misty pale light curtain between his hands flashed a few times and disappeared in an instant. "Uncle Zhang, my ability doesn't seem to be of much use here, what should I do?" Liu Yuan's ability is naturally the magic power emitted by the ancient appreciation technique, just exploring for a week, but I found that this unknown world deeper than the pit is also the same as when I was outside before, his technique is useless, then it is easy to explain, this above and below should be connected. "No matter, let's go out along this line first." Second Brother Zhang has no choice, he can't keep soaking in the river, right? Compared with the river outside, this river is obviously much calmer, soaked in the water, it is difficult to feel the movement of the water, but then, the two of them noticed that something is wrong at the same time, there is something in the river! The river is not very deep, but the touch of hard objects on the body makes them alert, yes, it is the white bones that erupt from the vortex when they are outside, floating sporadically, slowly moving with the river.

"Uncle Zhang, there aren't so many bones here." Casually fished out a piece of white bone from the river, he couldn't see the appearance clearly, but he felt unusually thick, Liu Yuan couldn't help but be a little puzzled, looking at the number of white bones gushing outside, it was far more than that.

Zhang Erhe also had a general expression, but it was pitch black, and he couldn't see it, so when he heard the words, he thought for a while, and said, "Yuan'er, you wait for me here for a while." After speaking, a fierce drill entered the bottom of the river, looking at the shape of the river at this time, it is not the trend of backflow, so the vortex outside should be in a suction state at this time, and after a while, Zhang Erhe re-drilled out.

"Yuan'er, it's all broken bones down here."

Liu Yuan thought for a while, then he was relieved and said, "Uncle Zhang, let's go downstream." Leaning against the wall, the pervasive darkness revealed the fear of the unknown, the two were not timid people, so they couldn't say that they were afraid, Zhang Erhe was in front, Liu Yuan was behind, and the faint sound of water separation echoed in this unknown world, making a loud noise.

"Uncle Zhang, what do you think should be needed for the water flow here to produce an upward jet?" After a long time without words, Zhang Erhe also seemed to have changed as if he had changed a person, in the past, Zhang Erhe should have talked the most at this time, but now, Zhang Erhe's silence made Liu Yuan extremely uncomfortable.

Zhang Erhe stagnated and stopped in the river, and the surroundings fell into a long silence, and the sound of the vortex flowing into the water in the distance could not cover up this silence.

"When the water is full!" Zhang Erhe's words moved Liu Yuan, his eyebrows were happy, and he said excitedly: "Uncle Zhang, how did you become so smart?" "When he was outside before, Liu Yuan always thought that there should be a rather turbulent underground river below, which also provided proof for the continuous suction power of the vortex, but after going down here, he found that the possibility of such a gentle river to make such a big impact and form a backflow force is almost zero.

"Yuan'er, it's not that I've become smarter, I can even evolve the scene here in my mind, it's like..."

"What is it?" Liu Yuan asked, there was a hint of eagerness on his face, being able to come up with the copper ball as the key had already made Zhang Erhe's imagination burst, and now Zhang Erhe's idea seemed to have become the key.

Zhang Erhe thought for a while and smiled bitterly, "I said that you don't laugh at me." ”

"It's okay, you say, whoever laughs at you, who's a puppy."

"I feel like I've been here before."

With a snort, Liu Yuan couldn't hold it back, "Uncle Zhang, did you sneak out to travel behind my back before?" Don't tell me you lived here before you met me. Liu Yuan said with a smile and quipped.

"What is this, I mean I dreamed of this place before, the scene is very similar, this kind of broken place, whoever comes is unlucky!" Zhang Erhe pursed his lips, slapped it in the water, and poured it on Liu Yuan.

"Haha, Uncle Zhang, this is a good thing, why didn't you say it earlier, let's go, the position of the tomb head will be handed over to you today." Liu Yuan did not doubt Zhang Erhe's words, if this was true, it would undoubtedly be of great help to their progress, thinking of this Liu Yuan was very excited, but the dark environment also made it difficult for him to see Zhang Erhe's expression clearly, that kind of struggle, looking deeply at Liu Yuan's direction, the things in the dream were actually a nightmare, and after Liu Yuan pushed him a few times, he came back to his senses from his memories.

"Yuan'er, can you promise me one thing?" Zhang Erhe walked in front, with the copper ball in his hand, and finally opened his mouth.

"What's the matter, Zhang Shu, to put it so sensationally, if this is really an ancient tomb, let's hide a few things secretly, what, I don't think you're very happy." In the past, Zhang Erhe must have been the first to say such things, but listening to his tone, he was not very happy, but a little melancholy.

"Do you promise or not?" Zhang Erhe stopped, turned around and put his hand on Liu Yuan's shoulder, unable to see his expression, but it would definitely not be good.

"Oh, okay, Uncle Zhang, don't give me this set of friendships, if the matter here is not resolved, do you think we can still go out? So we have to encounter any unknown things, don't ask me if I agree, first ask yourself if you agree. "After many years of tacit understanding, how could Liu Yuan not know what Zhang Erhe thought? It's nothing more than that there is danger, you run quickly, I'm in danger, you don't want to save it, it's just that they need this now? Mutual understanding is also necessary to trust each other, and working together to solve difficulties is the king.

Zhang Erhe was stunned for a moment, let go of his hand, smiled bitterly, and said, "The organ is in front." ”

In the memory of Zhang Erhe, this world is an underground circulation river, no entrance, no exit, the river circulates back and forth, surging endlessly, no matter how far they go along the river, in fact, they are all spinning in place, to put it bluntly, this is actually a tomb, and it is an extremely rare large tomb, the river outside as the upper part, is a courtyard structure, and the following one is a real moat.

"The merman cave, but there is no anger attached to ordinary tombs, but it is full of peace, alas, Uncle Zhang, give me the copper ball." It didn't take long for a small piece to bulge in the stone wall inside, if it weren't for Zhang Erhe's careful heart, it would be difficult for ordinary people to find it at all, let alone in this dark river where you can't see your fingers.
