No one can say clearly how big the space of the underground world is, and even Yang Fan, who has a delusional demon pupil, can't see the edge. (8) (1) Chinese Ω 『Δ Net'.81.

One is that there are layers of jungle shelter, the second is that the humidity of the underground world is too heavy, there are wisps of smoke everywhere, and you can't see anything clearly when you are far away, and then there is the reason for the light, even the most abundant noon can only shoot dappled sparse sunlight from a line of sky, and the place where the sun does not shine is still dim.

The five of them walked downstream for several kilometers along the zigzag riverbank, but they couldn't find another exit, it was already very far away from the first line of sky, and the light became extremely dark, if it weren't for the five people with a few tactical flashlights, it was estimated that even Yang Fan couldn't see anything ten meters away.

Yang Fan wondered very much, in such a dark underground world, how did those plants survive, such as where they are now, the tall trees are gone, the ground is almost covered with messy bushes and tenacious weeds, and in some places there are ** fallen leaves and muddy ponds, and even occasional swamps, which are almost difficult to get down.

The more the five of them walked, the more frightened they became, more and more swamps appeared, and as soon as they stepped down, it was a deep mud pit, if it weren't for the strength of everyone, it was very likely that they would fall into it.

At this moment, a child of a family walking next to him suddenly screamed, and Yang Fan behind him could see clearly that a rock-like thing suddenly burst into trouble and bit the thigh of the unlucky man.

"Damn, I was bitten by a crocodile, hurry up and pull it away!" The unlucky children of the family let out a continuous scream, and everyone was terrified when they heard it, many people had seen crocodiles, but it was the first time that they could bite the Yellow Order Martial Artist into a powerless situation.

In the almost dark environment, there was a crocodile hidden, this guy looked like a stone if he didn't look closely, and the unlucky child of the family happened to pass in front of it, and how could the crocodile, who had long been hungry, easily let go of such delicious food.

Yang Fan's eyesight is better than others, and at a glance, he knows that the unlucky guy is almost hopeless, this crocodile is not an ordinary crocodile that is common on TV, the length is actually close to four meters, a big mouth is like a big scissors, biting the prey and shaking it desperately from side to side, the strong physique of the yellow-rank martial artist can't bear it, and one of the thighs of the child of the family has been torn off by it.

Not only that, Yang Fan also saw that there were several rocks approaching in the knee-deep muddy water nearby, where are these stones, they are all very big crocodiles, and now the road ahead is impassable, so he can only quickly retreat and think of other ways again.

"Another crocodile is coming!" Yang Fan reminded everyone to turn around and run, crocodiles are the most terrifying creatures in the swamp, these guys are good at camouflage, and they seem to have mutated, they don't let their mouths when they bite them, the strong bite force and tearing force are unimaginable, even the Yellow Order Martial Artists can't last long.

Yang Fan ran away, and the others didn't have the idea of staying to be heroes, and even Yao Fatzi, who was a child of the family, didn't seem to hear the screams behind him, and ran harder than others, as for the old loach Director Zhang, he ran as fast as he could, and put himself in danger for an irrelevant junior of the family, that was not what the old loach should do.

The only one who ran slower was the yellow-rank martial artist among the children of another family, the reason for running slowly was not that he wanted to stay and save people, but that he was the lowest in cultivation among the remaining four, and the other three were all Xuan-rank martial artists, only he was a yellow-rank martial artist, and there was no way to run fast if he wanted to, so he could only be a meat shield behind the three of them.

At this moment, Yang Fan thought of the famous sentence, you don't need to run faster than the hunter, as long as you run faster than other prey.

To be honest, for three Xuan-rank martial artists, plus two yellow-level martial artists, if you have to deal with a few crocodiles, there is still a certain possibility of winning, even if it is a mutated crocodile, if several people can work together, it is not without the power of a battle.

However, several people have their own hearts, they all want to maintain their physical strength as much as possible, and it is impossible to take risks for others, Yang Fan believes that even if the crocodile behind him catches up and eats them one by one, everyone will not unite and fight together.

Fortunately, the crocodile didn't seem to like a dry environment, and as the four of them got farther and farther away from the swamp, the crocodiles finally stopped chasing, and the four of them looked at each other, and all walked back the same way in silence.

The original plan to go all the way down the underground river is obviously no longer feasible, and the upstream is getting narrower and narrower, and it is estimated that there is no way to find an exit.

The four of them briefly discussed for a while, and decided to return to the bottom of the first line of heaven, since the dome can have a line of sky, then along the crack of the first line of sky, it is very likely to find the mountain wall, with the strength of a few people, once they find a mountain wall that can be climbed, it is possible to drill out of the crack of the first line of sky.

Along the way, they rested twice, and the four of them finally returned to the vicinity of the first line of the sky without danger, because it was already dark, several people only roughly found the position, and they had to wait until tomorrow when the sun shone down to set the specific direction to move forward, and now they can only find a place to rest, recuperate their spirits, and cope with tomorrow's greater challenges.

Due to the lack of trust, the four of them were faintly divided into two factions during the break, Yao Fatzi stayed on a big tree with another child of the family, and Yang Fan stayed on another big tree with Director Zhang.

Although it was resting, it was impossible for both of them to sleep, Director Zhang and Yang Fan discussed, Yang Fan kept the second half of the night, and he himself kept the first half of the night, and the two took turns to keep vigil to avoid being attacked by sneak attacks.

Although a martial artist has been able to replace some sleep with cultivation, if he wants to be full of energy, adequate sleep is essential, Yang Fan's spirit has been highly concentrated for more than a day, and as soon as he relaxes at this time, he immediately falls asleep.

However, the vigilance of a Xuan-rank martial artist is very high even when he is asleep, and once something happens, Yang Fan can enter a combat state in a short period of time.

When it was almost two o'clock in the morning, Yang Fan woke up from his sleep, replaced Director Zhang, who was keeping vigil, and began to be on full alert, they had to wait until the sun shone down from the first line of sky before they could identify the direction through the sun, and the sun could only shine from the first line of sky between ten in the morning and two in the afternoon, that is, Yang Fan had to be on duty for eight hours.
