After Mu Qingmeng asked He Lang about his puzzlement, he said: "At present, there are indeed some extremely high cultivation demon cultivators in the Upper Cultivation Realm, most of them are summoned by other astral bodies, but all the masters are stationed in the four demon valleys, and if there is no major incident that needs help, they must not step out of the valley for half a step." ”

He Lang also knew from Mu Qingmeng that the four major demon valleys were the Flame Valley, the Ice Valley, the Demon Mist Valley and the Ghost Soul Valley.

And where they are currently is the Flame Valley, one of the four Demon Valleys.

She told He Lang that they had been stationed here to watch over important figures of the Demon Clan.

Because of this, they did not provoke people to cultivate, if it caused turmoil, their detention task would be affected, and the current detention of those felons is their most important task.

He Lang had heard Zhan Zhaohua say before, three thousand years ago, the Demon Emperor fell unexpectedly, which split the demon clan and the demon clan into two, it seems that this imprisoned person should be a rebel against the demon clan, and his skills are extremely strong, so he attracted so many demon masters to gather in one place, but he was not interested in the internal affairs of the demon clan at all, so he didn't ask more.

The two of them rested in place for a long time, and He Lang said, "Senior Mu, do you think we will go upriver from this river in a while?"

Mu Qingmeng nodded and said: "It seems that we can only go over there, this cave is simple and very simple, we have not seen any big branches along the way." ”

"Has anyone been in here before?"

"The Lord has been here for a long time, but after hearing that this place has been set up in a secret array, and no one has come down again. ”

He Lang finally knew how they found him and Lan Yun, it turned out that the masked man slapped a palm with a magic letter, after this magic letter was stained on the person, it would not disperse within three days, especially the people of the demon race, they were very sensitive to the smell, they jumped into the bottom of this crack under the instructions of Luo Manting, and then looked for the smell to find He Lang and the two, but after a few of them came down, they found that the way was blocked, and they could only look for other exits.

"Senior Mu, why didn't Luo Manting come in person?

"The Lord's brother is dying, and she can't get out of it. ”

Knowing this, He Lang's heart collapsed, he was very worried that the female demon would come to intercept him, if that was the case, it would be even more difficult for him to get out of trouble.

Thinking that Lan Yun was separated from him, he was even more anxious, and he said: "It was my eldest brother who was arrested with me, and I was very worried about his safety, and I really wanted to go back to find him." ”

"You don't know yet, while you're unconscious, we've traveled more than 400 miles in this cave, and if you go back, I'm afraid people won't be where they are. ”

He Lang was taken aback when he heard this, he thought that he would not walk for more than a hundred or ten miles, if this was the case, even if he went back to find it, he would indeed not gain anything.

However, thinking that Lan Yun has experienced a hundred battles, as long as there is a little opportunity, he will firmly seize it.

Thinking of this, he was not so worried, he stood up, patted his buttocks, and prepared to hit the road.

After that, the two jumped into the water again and went up the current to find a way out.

The water flowing upstream seemed to be very fast, but there were not as many whirlpools as seen downstream, and the water was a little warm, and He Lang was still lying on the other party's back.

The roar of the beast that had been heard at first when they entered the crack sounded again, the sound was desolate and gentle, and there was a faint sound of the chains clattering, and the roar was higher and higher, and they pondered in their hearts what was going on.

He Lang looked at the front nervously, lest there be some fork in the road, at this time the corner of his eyes flashed, and with the precious light emitted by the magic weapon of avoiding water, he saw something carved on the wall of the river.

The underground channel here, judging by the erosion of the rocks, should be as old as the formation time of this underground fissure, and there is something on it, it should not have been carved in recent years.

On closer inspection, the two sides of the river wall, which he had faintly seen from the wall of the cave when he first entered the ground, were depicted in the same dense French.

Some of the rocks have blurred or collapsed, but most are still well preserved.

A large part of the stone carvings were submerged in water, and the bottom part had been washed out by water, and it seems that there was no water here when they carved them.

If this is the case, whether they can get out of the waterway they are currently traveling is still two words.

The two of them had swam forward for nearly thirty miles of waterway, and although there was a magic weapon to avoid water, He Lang still clearly felt that the water temperature was slowly rising, and he had a faint ominous premonition.

With the beast's roar becoming clearer and clearer, Mu Qingmeng stopped and leaned to the edge of the water hole to observe around.

He Lang also grabbed the rock wall and swept around.

"Senior Mu, this situation is not quite right, how do I feel that this place is getting closer and closer to the place where we fell, and the beast's roar is clearer than I heard when I came. ”

"I also heard it, could it be that the four hundred miles we traveled before, in fact, we went in a big circle, and now we are turning back?"

Thinking of this, both of them were shocked, and now they were not half sure whether they could find a way out.

The two analyzed for a while, thinking that they still had to look forward, and if this road didn't work, they had to think of another way.

After swimming for more than ten miles, a fork suddenly appeared in front of them, and the two of them looked inward, and their nerves couldn't help but tense.

The waterway in this bifurcation is more than 60 meters high, about 80 meters wide, and at intervals on the top of the road, there are even inlaid with large luminous beads at the mouth of the bowl, illuminating a piece of light inside and outside the bifurcation.

And the roar of the beast must have come from inside.

He Lang immediately thought of the dark tunnel that Lan Yun had entered more than ten meters high.

Could it be a place inside?

"Senior, I want to go in and have a look, my eldest brother may be inside. ”

"Okay, I'll send you there, but it's weird inside, so be careful. ”

The fork in the road is obviously sloping downward, and when you look in from the fork, you can't see how far it is inside, and the further you go, the warmer the water is, the heat is steaming, and the fog is everywhere.

Because the space here is quite spacious, Mu Qingmeng did not go into the water again, but flew in the air.

Along the fork in the road, after more than ten miles of distance, I saw a huge stone gate more than ten meters high blocking the front.

He Lang felt that in this short length of ten miles, the depth of the downward slope should be at least more than seventy or eighty meters.

They saw that the water under the crack of the door was already boiling, if it weren't for Mu Qingmeng controlling a heat insulation magic device, the two of them would have been sweating profusely by now.

He Lang was dragged by Mu Qingmeng in the air for more than thirty meters, and his heart rose to his throat, if this fell, it would be cooked immediately.

Mu Qingmeng glanced at He Lang and said, "Boy, this is probably the place where the Qilin King is imprisoned, and it is full of magma flames. ”

When He Lang heard this, he was puzzled and asked, "Senior Mu, who is the Qilin King, and why is he imprisoned?"

It turned out that the important figure of the demon clan mentioned by Mu Qingmeng before was the Qilin King.

Mu Qingmeng said: "I have only heard from my ancestors that the Qilin King participated in the killing of the Demon Emperor three thousand years ago, and was later imprisoned here by Luo Tianye to lead the flames of heaven and earth. ”

Mu Qing was even more puzzled when he dreamed of He Lang, so he found a stone cliff that could accommodate him and fell down.

"The Qilin King is the felony imprisoned in this Flame Valley, I think it's better for us not to enter it, I'm afraid the interior is already a flame hell. ”

He Lang was shocked when he heard this, and hurriedly asked, "Isn't my eldest brother's life in danger?" Senior, I really want to go in and have a look. ”

"It's just that the fire-avoiding magic weapon on my body can't resist the baking of the flames of heaven and earth at all, I'm afraid we can turn into ashes as soon as we enter!"

When He Lang heard this, he gasped, and he couldn't help but worry about Lan Yun's current situation.

The two of them had no choice but to sit cross-legged on the rocks to make up for the lack of physical strength first, and then see if there were other paths to be found.

He Lang also knew that what the other party said was very right, if it was really a place where felons were kept, how could they let people enter casually?

Now he only hoped that Lan Yun did not enter it at that time, but turned back halfway.

The two of them rested for about half an hour, and were suddenly attracted by the sound of rumbling water in the distance, and at the same time felt that the water level below was constantly rising.

When I first entered, it was about 60 meters from the water to the top of the cave, but in just half an hour, it rose 6 or 7 meters.

Seeing this scene, both of them were shocked.

Mu Qingmeng picked up He Lang, and flew towards the fork when he came, and when he was only a hundred meters away from the fork, he heard the rumbling sound of the water endlessly, and the river poured into the fork like a huge torrent.

"No, I'm afraid the river will flow backwards, and if it continues like this, it is possible that this waterway will be completely submerged. ”

Seeing that the water level in the river was rising higher and higher, the two were about to dive out when they suddenly saw a black python jump out of the water.

This black python is seven meters long, more than one meter thick, and its whole body is jet black, but under this python's body, there are four legs.

He Lang saw at a glance that there was a person on the back of the python, and it was none other than his eldest brother Lan Yun, who he had been worried about.

Lan Yun also saw He Lang at the same time, and he waved his arm vigorously at the other party and shouted: "He Lang, I didn't expect to really find you, are you okay?"

"Big brother, I'm fine, where did you come from?" and pointed to the giant python under him and asked, "What is that?"

"Brother, don't ask, let's get out of here first, it's going to be flooded soon, you come with me. Lan Yun said loudly.

He Lang was pleasantly surprised, and he didn't care about asking about those reasons, so he just nodded vigorously.

The moment he saw Lan Yun, he let go of the heart he had been hanging.

"Seniors, let's follow them. ”

As soon as Mu Qingmeng saw the black python, he recognized that it was Gu Qianxun's true body, so he followed the black python and dived into the water.

When I dived to the fork, I found that the height from the water surface to the top of the road was more than 60 meters, but now there was not even 20 meters, and when I looked at the left and right waterways, the top of the cave was gone, and it seemed that it was submerged by water.

At this time, the river was still frantically pouring into the fork in the road.

The black python swam in the other direction from which the two of them had come.

Just as He Lang and Mu Qingmeng were about to turn and chase after them, three two-meter-tall strong men suddenly appeared in the water.
