Looking into the distance, the familiar green and quiet forest has disappeared, replaced by a mysterious scene shrouded in gray tones.

Between the two peaks, white stones can be seen everywhere, each of which is oval in shape and has a smooth surface.

The larger ones are even as big as a human head, while the smaller ones are about the size of a human fist.

As the line of sight continues to extend further, a vast area of ​​gray fog can be seen, and its blurred outline makes it difficult to see the specific situation inside.

However, the gray mist seemed to be confined to an area about a hundred feet wide.

On both sides, it was filled with blood-red light, like a surging tide constantly compressing and pushing towards the center.

However, once you touch the edge of the fog, it's like you've encountered an obstacle and you can't move forward at all.

“Is this place really the passage we are looking for?”

Lu Weiying exhaled, slowed down his pace, and asked softly.

"Indeed, I think this should be the entrance to the dungeon in the valley. Brother Lu, do you have any objection to this?"

Nanlong Hou was slightly stunned, then answered frankly.

"That blood-red light is undoubtedly the restriction in the valley, but this mist does not seem to be an ordinary thing."

"Regarding this kind of fog, is there any mention of it in the documents left by Master Cangkun?"

Lu Weiying turned his head and stared at the gray fog in front of him, and asked lightly.

"No relevant description was found. Perhaps he thought it was not critical information."

Nanlong Hou pondered for a moment and gave his answer.

"I always feel that there is something unusual about this gray fog. We still need to remain vigilant."

The old man surnamed Lu shook his head and reminded seriously.

"If we try it, we'll know whether there is a problem or not."

Chen Yun suddenly interrupted from the side.

"Fellow Daoist Chen, what you said makes sense. I happen to have a few orioles here, which I usually use to look for spiritual medicines. Now I can use them to explore."

Nanlong Hou clapped his hands in approval.

Hearing this, Lu Weiying did not raise any objection.

Then, Nanlong Hou took out an exquisite spirit beast bag from his waist, threw it gently upwards, and at the same time let out a low cry from his mouth.

A small bird covered with golden feathers flew out of the bag, rose into the air as quickly as an arrow, and then circled in the air.

Nanlong Hou waved his hand, and a green talisman flew out from his hand and hit the bird's body accurately.

Inspired by the talisman, the bird spread its wings and a small green shield instantly appeared on its body.

Nanlong Hou conveyed instructions to the bird through his spiritual thoughts. The bird let out a sharp cry, turned into a golden stream of light, and rushed straight into the gray fog in the distance.

Just as the bird was about to touch the gray fog, Chen Yun's eyes flashed blue, and he used his spiritual eyes to observe attentively.

However, when his eyes accidentally swept across a corner on one side, his expression changed slightly, and a strange look appeared in his eyes.

Nanlong Hou and Lu Weiying focused all their attention on Qianlili at this moment and did not notice anything unusual about Chen Yun.

The oriole had already plunged into the gray mist and disappeared without a trace.

Unable to see the situation clearly in the fog, in order to ensure safety, Chen Yun did not rashly use his spiritual sense to detect, but turned to look at Nanlong Hou's expression.

Nanlong Hou had his eyes closed, trying his best to establish a connection with the spirit bird.

His face looked calm as usual, which indicated that the spirit bird was not in immediate danger after entering the mist.

As Chen Yun was thinking this, Nanlonghou's body suddenly trembled, his face turned pale in an instant, and his eyes suddenly opened.

"It seems that there is a monster hidden in the gray fog, which actually swallowed up the oriole thousands of miles away in one breath. It's like a huge..."

Nanlong Hou's expression seemed extremely strange, as if he was a little unsure.

Chen Yun and the old man surnamed Lu looked at each other in surprise.

"It seems to be a giant python. That should be it. This gray mist is probably the evil mist emitted by this giant python."

Nanlong Hou thought for a long time, and finally nodded firmly to confirm.

"Python? This is indeed confusing. If this monster really exists, why didn't Master Cangkun mention it in his suicide note? Unless it is..."

“Unless this python entered this passage later.”

Chen Yun took over Lu Weiying's hesitant words.

"That's right. That's what Lu thought."

"What you two friends said is absolutely right. However, the giant python that can survive in this Fallen Demon Valley is obviously not an ordinary monster. It is probably some kind of ancient beast."

"If we want to reach the inner valley, we must kill it. We are really in trouble now!"

Nanlong Hou nodded in agreement, as if this was the only explanation that could make sense.

"Don't worry. Since this gray fog is not a forbidden barrier, but just a demonic fog, there is no need to be too afraid."

"It's just an ancient beast. The three of us working together should be able to deal with it. I believe it will never be able to defeat the ferocious fire toad beast!"

There was a cold light flashing in Lu Weiying's eyes as he analyzed calmly.

"Whether it is stronger than the fire toad is still unknown. But the situation is urgent, and we must destroy the giant python to feel at ease. The three of us must work together and act as soon as possible."

Nanlong Hou had a serious expression on his face, and a small flying sword shining with golden light came out of his mouth.

The old man surnamed Lu rubbed his hands continuously, and a dazzling white flag of law suddenly appeared in his hands.

Seeing this, Chen Yun smiled helplessly.

These two people acted decisively. Once they could no longer avoid the situation, they immediately decided to take action without any hesitation.

"My two friends want to get rid of this beast, and Chen has no objection. However, before that, should we invite another friend to show up and see it?"

"You have been hiding nearby and watching the battle for a long time. Has your curiosity been satisfied?"

Chen Yun suddenly turned to the side where no one was, and said solemnly. At the same time, he flicked his finger lightly, and several green sword qi broke through the air.

In an instant, sword energy suddenly exploded dozens of feet away.

A figure emitting yellow light all over his body and holding a giant shield appeared there strangely.

Nanlong Hou and Lu Weiying could not help but stare in amazement.

"I am so sorry! Please don't be angry, seniors. I just arrived here and will leave soon."

The figure in the yellow light was a skinny man in his forties. He hurriedly bowed to the three people and apologized, but his eyes revealed deep fear. "Huang Tianming, it turned out to be you!"

When the old man surnamed Lu saw this person, he couldn't help but let out a low cry of surprise.

"Could it be that Brother Lu recognizes this fellow Taoist?"

Nanlong Hou had a gloomy face and asked in a cold tone.

"This person is a cultivator from a small sect under our Tiandao League. Let's not talk about his cultivation level for now. It is rumored that he once obtained an invisibility talisman left by an ancient cultivator, and his ability to hide himself is amazing."

"I never thought it was true. He has been hiding here, and we didn't even know about it."

Lu Weiying looked stern, staring at the skinny man and spoke coldly.

"Three seniors, I am a newcomer here. I followed you here just because I was curious about the magic you performed."

Hearing the harsh words from Nanlong Hou and the other man, the skinny man's face instantly turned as pale as paper.

"What good can come of him following us secretly? Brother Lu, he is a member of your Tiandao League. What do you think of this?"

Nanlong Hou snorted coldly, then turned to ask the old man.

When Lu Weiying heard these words, his expression remained calm, but his eyes narrowed slightly.

"In my opinion, it would be best to destroy it."

The old man answered calmly, and before he finished speaking, he suddenly moved and disappeared in the white light in an instant.

When the skinny man heard the decision, he was horrified.

In an instant, he forgot his fear of the three Nascent Soul cultivators. A spiritual light appeared on his body and he turned into a rainbow and flew away.

However, at this moment, the old man performed some mysterious escape technique, and his figure reappeared where the man had just stood.

He raised his head and looked indifferently at the disappearing yellow light. Then he waved the French flag in his hand and threw it out.

The moment the flag left his hand, it turned into a hazy white wind, and like lightning, it swept the yellow light that had already flown more than ten feet away into the storm.

The huge shield in front of the man flashed only a few times before gradually breaking in the storm.

After the scream, he himself was unable to avoid being torn into pieces by the countless wind blades in the storm, leaving a bloody rain curtain.

When the old man surnamed Lu saw this scene, he nodded calmly, then waved his hand gently towards the storm, and the magic flag returned to its original white form and flew back into the old man's hand.

"Very good, Brother Lu handled it very appropriately. In this way, we don't have to worry about this channel being leaked out."

Nanlong Hou clapped his hands and laughed softly.

"This is not a big deal. A mere Jindan stage cultivator actually dared to follow us. It is really not a pity that he died."

Lu Weiying said nonchalantly.

Then he stretched out his hand and grabbed the ground, and two objects flew out from the blood-stained ground and fell into his hand.

One was the skinny man’s storage bag, and the other was a pale yellow jade talisman.

The old man surnamed Lu was not polite either. After taking a quick look, he put the items into his storage bag.

"This time, we are really grateful to Brother Chen. Otherwise, we would have really capsized in the gutter. However, Brother Chen was able to see through the ancient concealment secrets. No wonder he is so famous now."

Nanlong Hou turned to Chen Yun and said with a smile.

"It's nothing. It's just luck. The two Taoist friends could also see his whereabouts. It's a pity that we were careless at the time and gave him an opportunity to take advantage of us."

Chen Yun smiled slightly, acting as if he didn't care.

When Nanlong Hou heard Chen Yun's humble words, he shook his head but did not continue speaking.

At this time, Lu Weiying also returned to them.

"Let's act quickly to avoid any more trouble!"

The old man looked a little serious, but his words did make sense.

Chen Yun nodded, flipped his palm, and a bunch of crystal clear, glittering flags appeared in his hand.

"When we fight the giant python later, there will definitely be a lot of noise. Therefore, I will first set up a large isolation formation to control the impact within the restriction as much as possible."

"This way, we won't have to worry about other monks passing by nearby."

Chen Yun touched his chin and made such a suggestion.

"Brother Chen has indeed thought it through. This arrangement is the most appropriate."

The old man showed a satisfied smile on his face and praised sincerely.

Chen Yun immediately turned into a ray of green light and placed the flags in his hand one by one between the two peaks.

Soon after, a magic array covering a large area was set up.

The main purpose of this magic array is to suppress the sound and spiritual power fluctuations within a specific area as much as possible.

You know, without such quick preparation, it would be too difficult to complete such a complex array in such a short time.

When the green light transformed by Chen Yun returned to the front of Nanlong Hou and the old man, the old man surnamed Lu waved the flag in his hand and said in a calm tone:
"Since Fellow Daoist Chen has completed the arrangements, let me use this hurricane flag to disperse the diffuse evil fog, leaving the giant python with nowhere to hide."

As he finished speaking, the old man threw the treasure in his hand into the air again and began to chant in a low voice. Seeing this, Nanlong Hou immediately cast a spell, causing the golden sword in front of him to fly into the air.

In an instant, the golden light was as dazzling as the rising sun, and instantly became extremely huge.

In the blink of an eye, a huge golden sword about five or six feet long was suspended above the head of Nanlong Hou.

Lu Weiying stopped chanting the spell and lightly touched the flag with his finger.

The flag was sensed and began to tremble violently. It quickly unfolded and shone with light that was impossible to look directly at.

Then, hurricanes similar to the previous ones burst out from the flag and transformed into dozens of white wind dragons, roaring towards the gray fog in the distance.

The golden giant sword buzzed and flew as fast as lightning. It flew above the gray fog and began to circle.

Obviously, Nanlong Hou was waiting for the gray fog to dissipate. Once the monster appeared, he would immediately use thundering means and attack with all his strength.

Chen Yun silently waved his sleeves, and a bowl with silver light flew out from his sleeves. It then turned into a ball of silver light and flew away into the distance.

This bowl is one of the few ancient magic weapons that Chen Yun obtained after defeating Mulan Fashi. Although it is powerful, Chen Yun used it to attack, more likely for the purpose of testing.

More than a dozen wind dragons took the lead and rushed violently into the thick fog.

The gray fog rolled endlessly under the impact of the wind dragon. A large amount of fog was rolled high up by the hurricane and then torn into pieces.

The gray sea of ​​fog gradually weakened under the erosion of the hurricane.

However, this situation did not last long, as a strange sound similar to "hissing" suddenly came from the depths of the fog. (End of this chapter)
