Tianyou also knew at this time that it was very dangerous to enter the tomb again, and when he saw Zhou Fan's worried expression, he knew that Zhou Fan was not exaggerating, and he was even guessing that Zhou Fan had some words that he didn't dare to say.

I couldn't help but weigh it in my heart for a while and said, "No, it's too dangerous if you let you go to the battle alone, there are still many caves down there, let's go see if we can find a passage first, and the water in the river has dried up, let's try to walk upstream, maybe there will be a passage anywhere, in short, I don't approve of breaking into the formation." ”

Everyone didn't know what to do at this time, and when they saw that Tianyou had already made up their minds to pay attention, they didn't think much about it, Feng Long glanced at Tianyou and said: "Tianyou said so, then let's go and find out if there is any other way out." ”

"Since there are no opinions, Na Zimeng will take the lead first, and after going down, first see if Hu Jiao's body is still below, and tell us after confirmation." Zhou Fan saw that everyone was unanimous, so he threw the rope to Feng Long, and after instructing everyone on some matters, he turned around and came to the tomb outside the tomb and continued to stare at the tomb and coffin inside.

"It's okay, the body of the tiger Jiao is gone, it's safe here, you can come down." Zhou Fan just looked at some eyebrows and heard Zimeng shouting below, and he was helpless at the moment, and after sighing secretly, he stood up and walked to the edge of the cave, only to see that Zimeng was already sitting and smoking below.

"You go down first, I'll break off..."

"But..."

"It's okay, you go down first, Qing'er I will take care of it, there will be no danger here, I still want to observe the tomb again." After Zhou Fan motioned for everyone to act, he turned around and stared at the tomb from afar.

He always felt that it was not as simple as he imagined, although he could roughly see that the division and arrangement of the formation still had a specific effect. But he always felt as if something was missing, but he couldn't say it.

However, there was an inexplicable sense of crisis in his heart, and Zhou Fan knew that every time he had this kind of premonition in his heart, something bad would always happen, so he wanted to know more about the tomb.

"What's wrong with you, God bless them calling you." Just when he was thinking about it, he suddenly heard Qing'er's gentle voice, and immediately Zhou Fan reacted from his thoughts, turned around and saw that there were only two people in the cave at this time, and Tianyou and several people had already arrived below.

At this time, it is impossible for him to stay anymore, if he still doesn't go down, there will be something down in a while, he is worried that Tianyou and a few people may not be able to cope with it, so he can't help but step forward and hug Qing'er and say, "Hold me tight, and we will go down too." ”

"Well, I'm not afraid of anything with you. ”

"Hehe" Zhou Fan glanced at Qing'er in his arms, and suddenly felt a sweet taste in his heart, and immediately kissed Qing'er's forehead, which made Qing'er even more shy to lean on Zhou Fan's arms.

"I'll rub, these two people," Feng Long looked at Zhou Fan and Qing'er above and couldn't help but be speechless for a while, holding his forehead with a look of shame.

Zimeng didn't care about the two, and when he saw that the two were still kissing me and me, he immediately yelled at the two: "Still in love, if you don't come down again, Lao Tzu won't wait for you." ”

"Snort......"Zhou Fan couldn't help laughing when he heard this, "Okay, come on." ”

After saying that, Zhou Fan took Qing'er down to the bottom, at this time everyone was already standing on the edge of the river, each shining a flashlight on the huge hole under the river, Zimeng also tried to throw one or two stones down, but there was no sound for a long time, it can be seen that this hole is very deep.

"The tumbling of this river should be related to this hole in the ground, if it is not a fountain mouth below, it should be a convection outlet."

"A convection outlet? What do you mean? Zimeng stared at Feng Long and was puzzled.

"The convection outlet refers to another stream of groundwater that passes through, which means that deeper in this underground river, there is also an underground river, and the two jumping rivers are connected by this hole.

If the deeper underground river is rained or overflowed, it will continue to gush into this outlet, and when the river below keeps gushing up, it will form the tumbling of the river surface as before.

Because the river is flowing, when the water rolls, the impact and velocity of the river will cause the water from the hole to pour back again, forming the wave of the river that keeps tumbling.

But neither the mouth of the fountain nor the outlet of the underground river can go down rashly, and now that the river has suddenly dried up, there is no reason to be found, and perhaps it will suddenly erupt and drown us at once.

So let's see if there are any other openings around, if it really doesn't work, we are going up the river, in short, we don't go down the river unless we have to. Feng Long said as he looked around.

At this time, everyone also didn't care about saving power, except for the two women, all five of them were each with a strong flashlight, with the cooperation of a group of people, the entire underground cave was almost clear and transparent.

"Did you find anything?" Zhou Fan returned to the river first, and looked at a group of people, but they all looked disgraced, and knew that everyone had found nothing.

Sure enough, as soon as Zhou Fan's words fell, he saw Feng Long and said: "It seems that we misjudged before, although there are many karst caves here, almost all of them are wide on the outside and narrow on the inside, and the deeper you go, the smaller the holes, and even some of the caves are already dead ends at the end."

I guess these caves were formed by long-term immersion in underground river water, which caused the soil layer to collapse, rather than artificially created passages, so our previous judgment would have been wrong, and not only did this place not have a way out, but it could even be a dead pit. ”

"It's the same on my side, none of the caves are open, it seems that we can only ...

"Don't take the risk for the time being" Zhou Fan immediately interrupted Zimeng's words when he saw this, "The layout above is too big, I don't have a clue for a while, let's go up along the river and see what the upstream of the river is, if the upstream is a dead end, it's not too late for us to retreat along the road." ”

"I'm for it,"

"I'm in favor of it too"

"You all say so, then let's go, don't waste time, if we drag on here for a long time, we will be in danger for one more day." Tianyou saw that Zimeng and Feng Long had no opinion, and he couldn't take care of everything anymore.

Although he was worried that Twilight would be in danger, but at this time everyone agreed that he was walking the river, and he couldn't say anything, I don't know why he had noticed that Twilight looked at him a little wrong since some time ago, but he couldn't say what it felt, so he could only be careful everywhere for fear that Twilight would be in any danger.

After the unification of the decision, Zimeng climbed into the cave again, intending to take the rope down, although each of the four people, each hand a rope, but can be recovered as much as possible, otherwise a few people will have no rope after a few places, Zimeng is busy when the crowd is busy, everyone has been resting by the river, sure enough, Zimeng's speed is very fast, and after a while, he came to everyone with the rope.

"The river is not very deep, in some places it is only two or three meters, so let's go up a little bit and find a place with a low slope to go down." After that, Zhou Fan pulled Qing'er to take the lead first.

The river is more than ten meters wide, the deepest is only eight or nine meters, and some shallow ones are only two or three meters, so everyone went down to the bottom of the river smoothly, but after a few people came to the bottom of the river, they found that the karst cave under the river was much larger than what they saw above.

Everyone had to carefully follow the edge of the river and cross this bottomless hole, although the cave occasionally blew a strange wind, but everyone still had a thrilling pass.

At this time, a group of people came to the gate of the river, and after Zhou Fan and a few people came down, they found that in fact, this huge underground space was closed, and only the upper and lower ends of the river could walk, and the underground river still passed through the mountain.

When the river filled the river, everyone couldn't see the intersection at all, they could only see a pitch black, but even if everyone came here, they would be blocked by the mountain, if the river hadn't dried up now, they really wouldn't have found the gate of the river.

As for the downstream, there was no obstruction, but everyone could tell from the turbulent water that there should be no mountains downstream, so the water flowing down the upstream was slow, until the river flowed to the hole in the middle, and the water began to become extremely turbulent.

After a group of people walked through the mountain of the sluice water, they came to a place that made them feel even more shocked, and at this time, Zhou Fan and several people couldn't help but breathe a little tight, and they all looked at the scene in front of them in amazement.

I saw that what appeared in front of them was an underground space that was even taller than just now, a hundred meters high, and the surroundings were also huge, and what shocked them even more was that they were actually in a bottomless abyss.

Everyone could only barely see where they were from the light in their hands, as if it was still the same river just now, but this section of the river was obviously many times wider and deeper than the one before they crossed the mountain, and now everyone felt as small as ants when they stood at the bottom.

"Roar" Just when everyone was shocked by this, suddenly a deafening roar sounded, Zhou Fan's face immediately changed when he heard this voice, and he said secretly: "It's not good." ”
