The dark clouds in the sky still heard the sound of muffled thunder.

Looking at the steep cliffs, it is definitely not easy to go down to the bottom of the valley.

Luckily, they carried some ropes, but they weren't very long, and they were originally just meant to be used to secure people in times of danger.

"You go down with a rope first, I'll be the last one to go down!"

After considering the length of the rope, Yuntian found a few places to stay.

But the rope was not long enough, so they had to divide it several times before they could go down, and the last person was not allowed to use the rope.

So Yun Tian grabbed the yin and yang thorns and said to the other three people.

"Then I'll carry your gear!"

Of course, Niu Boyu knew that the slippery rock wall was extremely dangerous.

Once there is no rope, it is very dangerous to climb with only two hands, so I offered to carry equipment for Yuntian.

"That's fine, be careful!"

Yun Tian nodded, the climb under this storm is absolutely unimaginably difficult, and it is good to be able to distract a little less.

So, after fastening the rope to a sturdy tree trunk, the three mermaids rushed down.

Tang Xi, the lightest, took the lead in going down to the foothold, and after several tests with an ordnance shovel, and confirmed that it was safe, Niu Boyu and the big-faced tiger fell.

It wasn't until the three of them fell to a stable place that Yun Tian finally untied this end of the rope and tied it around his waist.

"Slow down, be careful!"

When they came down, the three of them also kept trying various footholds, in order to explore the way for Yuntian.

Niu Boyu and the big-faced tiger tied the other end of the rope to their bodies.

Once Yuntian is in danger, the rope on his body will also play a certain role in safety.

Holding the rock wall in one hand and the fish intestine sword in the other, Yuntian climbed on this cliff with his bare hands.

Little by little, I climbed down, but fortunately, the rock wall washed by the heavy rain had been washed away, and the floating soil had been washed away.

The rocks that leaked out were relatively strong, so Yuntian smoothly joined everyone.

But they didn't have time to rest, because the height of this mountain was not ordinary, and as the clouds fell, Tang Xi set off again.

In this way, after a long morning, they landed in the valley without danger.

When the clouds fell on them again, everyone gave them a mouthful.

"I thought it was crazy to jump wings in this weather, but now it looks like there's more to come."

Niu Boyu couldn't help but raise his head, looking at the high mountain that stretched out into the clouds, and couldn't help but say.

He couldn't have imagined that they had fallen from that position.

The same is true for the big-faced tiger, the mistake of landing yesterday almost made him fall into the abyss.

But now, they have to keep walking in the abyss.

"Okay, pay attention, this road is a shortcut, and it may also be Huangquan Road!"

Yun Tian put away the rope, put it on his body again, and looked at the bottom of the ditch that had been washed by the mountain torrent and said.

The valley between the two mountains, although relatively flat, can be fatal in the event of a large-scale flash flood.

But the task is urgent, if you want to march from those broken mountains, I am afraid that you will not be able to reach the target point in ten days.

"Got it!"

The three of them agreed, and they also put away their carelessness, the time was not early, and they had to hurry as soon as possible.

Along the ravine washed by the torrent, in some places it was waist-deep water.

In the turbid water, there are no fresh fish, and some are all kinds of dead branches and rotten leaves.

The trek has just begun, and although it is relatively easy to walk, there is no road deep in the mountains.

They can only turn left and right along the ravine, which is a huge physical drain.

Walking and stopping, the sky was still gray, and the thunder flashed, but fortunately, in addition to the hard work, there were no other problems.

In the mountains, in addition to the howling wind, it is difficult for beasts and birds to sing, and it seems that this natural disaster has made them avoid it early.

"Hold on, let's go a little more!"

Looking at the watch on his wrist, Yun Tian said to the three people again.

They had been trekking for more than ten hours from morning to now, but the distance they had walked out was not too far.

Therefore, they must hurry as soon as possible, and strive to reach the designated area before noon tomorrow, otherwise if they slow down, those mercenaries will not know where to go.

"Okay, we'll hold on!"

Tang Xi, Niu Boyu and the big-faced tiger nodded, and they all gritted their teeth as they supported each other.

Fortunately, although it was difficult to deal with this heavy rain, they did not lack water to drink, and with food to ensure that they had much better energy after filling their stomachs.

I walked for more than an hour, but it was completely dark.

The rain is getting lighter and lighter, but the wind is still quiet, and this change makes the four of them much better.

"How is this thunder like a stinky fart!"

While walking, Niu Boyu said that the rolling thunder in the sky was so low at this time.

"It doesn't seem like thunder!"

Listening to Niu Boyu's words, the big-faced tiger also stopped and looked up at the dark clouds.

The voice was low, like the roar of a hippopotamus, and the whole earth shook a little with that sound.

"yes, that sounds weird!"

Yun Tian and Tang Xi also stopped, trying to identify the location where the voice came from.

But they were surrounded by mountains, and they were at the bottom of the ditch, and they couldn't tell where the muffled sound with the echo came from.

As the four of them stopped, the ground began to shake constantly.

After a day's journey, they were also disturbed by several aftershocks.

But fortunately, the aftershocks were not too big, and the sporadic rockfalls did not bother them.

But at this time, the shaking of the earth was not violent, but it lasted for a long time, and the dull sound continued.

"Something is wrong, it's not thunder, it's a torrent!"

Yun Tian, who suddenly reacted, hurriedly shouted at everyone.

Such a feeling is not the dullness of thunder, but the terrifying sound of the torrent pouring down.

"What then?"

Yun Tian's words suddenly made the three of them stunned, now that they are at the bottom of the valley, wouldn't the flash flood be fatal.

"Hurry up the mountain!"

Yun Tian raised his head and looked at the cliff on the left that was less than fifty meters away from the four people, and at the same time took out a lighting gun from his waist.

Pulling the trigger, a red basket and two flares flew into the air with a whistling light, and the bright light suddenly shrouded the earth.

By the light, the four of them hurriedly ran towards the rock wall, the potholed rock wall was the only place they could escape.

In the blink of an eye, the four people who came to the bottom of the cliff were all desperately climbing upwards at this time, and the muffled sound was getting louder and louder at this time.

"Hurry up!"

With the flare in the sky, Yun Tian couldn't help but look in the direction where the sound came from, and suddenly felt his heart tighten.

The flood roared down from afar like a beast.

The dead branches and rotten leaves mixed in it formed a terrifying death aura.

Along the way, the trees that escaped were washed away in an instant, tearing through the air and making people's scalps tingle.

Such floods are by no means ordinary mountain streams, and the only possibility is that the dam upstream will burst.

Tens of millions of tons of floods are more terrible than beasts, and if they are swept up, they will surely die.

The four people who climbed the rock now also drove out of the strength to feed, and a pair of fingers were deeply clasped on the cliff.

Fortunately, there were some gaps in the cliff wall, and the four of them began to break away from the ground little by little.

The speed of the flood was as fast as thunder, but now it is like thunder.

The torrent roared, like a herd of frightened wild horses, rushing from the valley, overwhelming.

The eardrums of the four people were also shaken by the loud sound.

Landslides and cracks, mountains and seas, and waves are all powerless when they are immersive.

Now the only thing they have in their minds is to climb up.

"Tang Xi, hurry up!"

Yun Tian looked at Tang Xi while climbing, after all, she was still a woman.

There are some things that are inherently destined to be insurmountable, especially in terms of physical fitness, there is still a gap between female soldiers and male soldiers.

It's not that she doesn't work hard enough, it's just that a woman's musculature can't be compared to a man who has always been mainly hunter-gathering.

Among the four people, Yuntian and Big-faced Tiger are both veterans of Sky Wolf, not to mention their strength and physical fitness.

Although Niu Boyu came later, he also caught up with his hard work.

The distance between him and Tang Xi was quickly filled and surpassed, which was also something that could not be helped.

"I can't crawl!"

Tang Xi's face was pale at this time, and she was lying on the stone wall, her arms were like a thousand catties.

The rain drenched her hair, and she was embarrassed by the fact that it was sticking to her face.

"It's okay, hold on, I'll help you!"

Of course, Yun Tian could see that Tang Xi was no longer good, so he stretched out his hand and tied the rope around her waist, and the other end was tied to his shoulder.

"Brother, don't do this, I'll drag you down!"

The surging flood is coming, if it is a little slower, it will kill here, Tang Xi can't drag down the clouds.

"Silly girl, what are you talking about, I won't leave you alone!"

Yun Tian smiled at Tang Xi, although he was also very tired, but the responsibility made him not stop.

As soon as he gritted his teeth, he climbed up again, and with his pull, Tang Xi below was also a little more relaxed.

But at this moment, the flood that seemed to be galloping like a thousand horses had come to their side, and the huge torrent, following their footsteps, rushed down.

"Oh my God, it's almost over!"

Niu Boyu looked at the black torrent under his feet, if he slowed down, the four of them would be buried here.

"Don't talk nonsense, hurry up and climb, the rain is coming!"

With the rush of the torrent, the heavy rain that had stopped in the sky poured down again, and the big-faced tiger hurriedly said to Niu Boyu.

"yes, climb up hard!"

Yun Tian raised his head and looked at the position above his head, and he had only half-climbed with all his strength.

But just as he was about to work harder, his shoulders suddenly tightened, and Tang Xi under his feet let out a miserable scream.
