This strange black mist filled the cave, and the light of the torches could not shine too far, and the slightest distance between the two of them would blur their figures.

Yang Zhan, who had always been bold, was a little scared in his heart, but the stubbornness of the young man made him move forward with a hard head. Mu Feng had seen a lot of this kind of scene in his previous life, but he seemed more calm.

In this silent cave, the sound of the young man's violent heartbeat was very loud.

"Come closer, don't be scattered. Mu Feng said in a low voice.

Although this cave is strange, it has come to this point, and it is impossible to turn back. Mu Feng was also curious whether this was an ordinary cave or if there was another secret hidden by no one.

The two of them walked slowly towards the deep and shallow feet in the cave, the light at the entrance of the cave had long since disappeared, and the light of the two torches dispelled some of the black mist, but they could also see the cave roughly clearly.

At this time, Mu Feng was already in the front, and had been paying attention to the flame of the torch, and found that there was no lack of oxygen, and these black fogs did not seem to be very harmful to the human body, and there was no uncomfortable reaction when inhaled into the human body. Therefore, his heart also relaxed a little, and led Yang Zhan to slowly walk towards the depths of the cave.

There was nothing strange about the firelight, it was similar to a normal cave, the only difference was that there was a thick black mist in the air.

At this time, only a "whirring" sound was heard, as if something was passing through the air, but because the flight speed was too fast, neither of them could see what it was.

"Don't panic, it's like it's just a bird. In fact, Mu Feng didn't see what it was, but he was afraid that he couldn't solve the problem, and when he saw Yang Zhan's face flustered, he had to say a few words to comfort him. After all, Yang Zhan was only a fourteen-year-old boy, and it was normal to be afraid.

When venturing deep in the mountains, calmness comes first. If you can't calm down and deal with emergencies calmly, then there is only a dead end.

Yang Zhan listened to Mu Feng's words, calmed down, and cheered for himself: "I'm afraid of a bird, today we meet ghosts and kill ghosts, and when we meet Buddhas and kill Buddhas, the big deal is that our heads have a big scar." ”

Yang Zhan's words echoed in the empty cave, and suddenly aroused the young man's blood, and for a while, the two of them were full of blood and courage, and even the pace was quickened a lot.

The two walked for a while and came to a turn, but stopped, looked at each other, and were dumbfounded. In front of the two of them, the cave that was originally a passage was divided into two holes.

"What should I do?" Yang Zhan set his eyes on Mu Feng, now he had no idea at all, so he could only rely on Mu Feng.

"Why don't we go back. Mu Feng said a cold word, which made Yang Zhan almost faint.

"Don't worry, let me think. Seeing Yang Zhan posing as a jiashi who wanted to repair himself, Mu Feng said seriously.

He took a closer look at the two openings, and found that the black mist in the left cave was thicker than the one on the right.

After thinking about it for a while, Mu Feng did not hesitate to take Yang Zhan to the left cave entrance. However, before entering the hole, he made a mark in a prominent position at the entrance.

The two walked again, and two more holes appeared in front of them. After making another mark in the conspicuous place of the cave entrance, Mu Feng then chose the right hole with thick fog to enter.

When the two of them didn't know how many times Yujian forked in the road, they finally stopped, and they were surprised to find that there was a mark they had made in the prominent place at the entrance of the cave.

"Why are you back again?" Yang Zhan's face became a little ugly.

Mu Feng frowned and said in a low voice, "This shows that we have been circling around the cave, and this cave is a labyrinth. ”

"What a place!" Yang Zhan cursed.

"Just now I carefully observed the hole on the left at the beginning, it seems that the black mist is thicker, this black mist we inhale and do not feel any discomfort, so it should not be harmful to the human body, just a trick to cover the eyes. So the thicker the fog, the more the hole is the source of the black fog. ”

Mu Feng pointed to a mark at the entrance of the cave, and then said, "But the mark I made at each fork just now is different, this mark is the fifth mark I made, and I didn't understand what it was?"

Although he knew that the cave was a labyrinth, he had not yet mastered the key to cracking it.

However, they didn't know that this black fog was called Devouring Poison Mist, which had no effect on ordinary people, but it had a great restraint effect on Xuan Li. If a martial artist above the Qi Transformation Realm inhales this kind of mist, his power will be greatly reduced, and those who have cultivated a little worse are more likely to lose their Xuan power and die of poison.

"Mu Feng, what should we do now? or do you want to go back?" Yang Zhan asked.

"I'm afraid I can't go back, if I'm not mistaken, this is a phantom labyrinth, we're already deep in it, and finding the entrance is just as difficult as finding the exit. Mu Feng shook his head and said, he felt that this cave seemed to have been magical, otherwise they would definitely not have a reason to walk back.

"What should I do then?" Yang Zhan was a little anxious. They all came to Luoshen Peak secretly behind their families' backs, and no one knew. If you are trapped in a cave, you can only die.

"Don't worry, let me think about it. ”

Mu Feng said calmly, his brain spinning rapidly. His intuition told Mu Feng that this black mist was still the key to cracking the labyrinth of the cave. He even felt that they were not very far from the exit of this cave labyrinth.

Mu Feng suddenly had an idea in his heart: the mouth of the cave they passed through, some of them were forks in the road that played a confusing role, and some were impassable dead ends, they should not be exits, and the exits should be in ......

Thinking of this, Mu Feng had a bold guess in his heart. He took Yang Zhan back into the mouth of the cave with thick fog, and this time he asked Yang Zhan to carefully observe the stone wall in the cave, and sure enough, he found it soon.

At the top of the side of the stone wall in the cave, some small holes were found, and these small holes kept emitting black mist, and in the thick fog of the cave, it was extremely difficult to detect the existence of these small holes without careful inspection.

The existence of these small holes further proves Mu Feng's guess. These black fogs and these caves only serve as a confusing effect, and the entrance to the real caves is on the stone walls of these caves.

After careful inspection, Mu Feng finally found that the stone wall of a cave was a little weird, and there were several subtle protrusions in the inconspicuous place of the stone wall.

"Click"

Mu Feng gently twisted the raised part of the stone wall in order, only to hear a small sound, only to see that a part of the stone wall of the cave slowly moved, gradually revealing an entrance.

Looking at that entrance, Yang Zhan's admiration for Mu Feng reached an unprecedented height, although Mu Feng's martial arts cultivation was not as good as his own, but his knowledge far surpassed his own.
