The surrounding flames exuded a scorching aura. Du Yun's spiritual consciousness was quite powerful, especially with the blessing of Xuantian Vein, which was far superior to other monks in the late stage of transformation.

After thinking about the voice just now, Du Yun suddenly remembered Lin Yifei, the senior student who had a grudge against him because of Li Xiaotong.

Ever since the two had a decisive battle, Lin Yifei had been silent for a period of time, and then disappeared. Du Yun was still very vigilant in his heart, and did not arrogantly think that Lin Yifei was afraid just because he didn't come to him.

On the contrary, Du Yun understood Lin Yifei's temperament very well. As long as he got the chance, he would definitely take revenge on him. However, when he was in the academy, so much time had passed, and Du Yun almost forgot about him.

Now that I think about it, I can't help but shudder in my heart. What is Lin Yifei doing here? His strength is in the middle stage of transformation, and he is also a leader of the Academy's Tian Serpent Gang. It is not his character to wander on these three levels.

"Secret room?" Vaguely, Du Yun seemed to hear such a voice. He was confused and thought about it for a moment. Then Du Yun gritted his teeth, put away Fang Tian's painted halberd, and followed cautiously.

The strong flames, flashing sparks, and the scorching breath filled the air, making people tense up. Du Yun walked quietly, his consciousness rippled, and a picture suddenly appeared in his mind.

More than two hundred meters ahead, Lin Yifei was walking with two boys. The three of them acted strangely, and they often looked around cautiously, as if they were afraid of being discovered.

Du Yun's curiosity was aroused and he couldn't help but follow him subconsciously. His consciousness range was very large, so within two hundred meters, the three of them couldn't detect him at all.

In this Fire Cloud Cave, everyone's consciousness will be restricted. Du Yun's limit is only about three hundred meters, but Lin Yifei and others can detect up to one hundred and fifty meters, which is already very good.

Therefore, there was a safe limit two hundred meters away from them. Du Yun did not dare to get too close for fear of being discovered by them. Through the induction of spiritual consciousness, it turned out that the cultivation levels of Lin Yifei and the others were in the late stage of transformation.

It seems that after the duel with him, Lin Yifei must have practiced hard. Otherwise, based on his qualifications, even if there are a lot of resources for him to practice, if he doesn't work hard, he will not be promoted to the late stage of transformation in such a short period of time.

"Master, do you think we can succeed this time?" Next to Lin Yifei, a handsome young man with a worried look on his face whispered.

"Don't worry, I was alone last time and couldn't deal with the Flame Beast King. But don't worry, the three of us can definitely deal with it." Lin Yifei frowned, then thought about it and said with confidence.

"Haha, with the Hall Master here, a mere flame beast king can't do anything to us." On the other side of Lin Yifei, a thin young man with a slippery appearance was flattering.

However, it seemed that Lin Yifei was very satisfied with his flattery, and he couldn't help but show a proud look on his face. The other young man frowned tightly, seeming to be very cautious.

"Huang Cheng, don't worry, nothing will happen." Lin Yifei showed impatience on his face and glanced at the frowning young man.

"Hey, Hall Master, it's better to be careful." Huang Cheng smiled sarcastically, but he was uneasy in his heart, always feeling something was wrong.

But seeing the confident looks of the two of them, he knew that it would be useless to talk more, so he had to remain silent. Lin Yifei's background was too big, and he did not dare to offend him too much.

Two hundred meters away, Du Yun listened to their conversation, secretly frightened. Is there a Flame Beast King on this third floor? Thinking of this, a chill suddenly hit him. Du Yun thought about what he had done these days, and finally realized,

I am still a bit arrogant.

Fire Cloud Cave is full of crises, but after Du Yun came here, everything went smoothly. Except for the time when he was promoted, he didn't encounter any big crises, so he relaxed his vigilance.

But after listening to the conversation between Lin Yifei and the others, Du Yun suddenly realized that he had been careless. Judging from their appearance, the three monks in the late stage of transformation were not absolutely sure about dealing with the Flame Beast King. What if he encountered it alone?

Thinking of this, Du Yun couldn't help but shudder. Then he quickly put away his shaking mind, took a deep breath, moved his body, and continued to follow.

He also wanted to see what the Flame Beast King looked like. And through their conversation, it seemed that the goal of the three of them was not the Flame Beast King, but some kind of secret room.

When he came here, the two vice-deans told him that although there were dangers everywhere in the Fire Cloud Cave, there were also opportunities. As long as the blessings were deep, there might be unexpected gains.

Originally, Du Yun thought that the biggest gain here, besides the crystal nuclei and furs of the flame beasts, was the fire element. But now seeing the actions of Lin Yifei and the others, Du Yun knew that besides the opportunities he knew

In addition, there is another cave here.

After walking for about two hours, the map route in Du Yun's mind no longer depicted this place. However, Du Yun still secretly memorized the route here along the way, so he was not afraid of getting lost here.

The further forward, Du Yun felt more and more the flames here were hotter, and the fire clouds in the sky became thicker. Hot langs rushed towards him, and even though Du Yun had a profound cultivation, he couldn't help but let out a trace of it.

Sweat stains.

Quietly wiping the beads of sweat on his face, Du Yun discovered that Lin Yifei and the others had stopped. Then, he saw the three of them suddenly separated and headed in three directions.

Du Yun was shocked, had he been discovered? After a moment, he understood. It turned out that they had arrived at their destination, and the secret room they talked about was in this area.

Du Yun heard the three of them roaring, as if they were arranging something and conveying their messages to each other. After a while, the three of them gathered again.

"You two have successfully arranged the formation. Once the Flame Beast King comes out, you will activate the formation." Lin Yifei glanced at Huang Cheng and the other person and asked softly.

"I have no problem here, Xie Bin, what about you?" Huang Cheng replied in a deep voice, his face full of solemnity, and then he glanced at another thin young man.

"There's no problem on my side." Xie Bin replied, his face equally solemn. Although he had flattered him just now and said that as long as Lin Yifei was here, there would be no problems, but when he got here, his previous hypocritical expression changed and became serious.

"Well, in about an hour, the Flame Beast King will come out. We will wait for the opportunity to act. This Flame Beast King has some wisdom and will not be easily fooled." Lin Yifei looked at the sky and seemed to have thought of something.

Then he said in a deep voice.

Immediately, the three of them looked at each other, and then nodded silently. This time, they were well prepared. In order to deal with the flame beast king, they had made up their minds and even brought out formations.

Du Yun watched from a distance, secretly frightened in his heart. He had heard from the two vice-presidents that some monks specialized in formations. People like them were called formation masters and could refine powerful formations.

Formation.

Depending on the level of personal cultivation, some powerful formation masters can even rely on formations to deal with a large group of people who are stronger than themselves without being harmed.

So when he saw the three of them taking out the formation, Du Yun couldn't help but be moved. The background behind Lin Yifei should not be underestimated.

However, Du Yun was not afraid. After thinking about it, he decided to wait quietly on the outside. When the Flame Beast King came out, it would be good if they could fight to the death and be the fishermen themselves.

This area was extremely hot, several times hotter than other places on the third floor. Du Yun had to run his golden veins, mobilize his spiritual power, and add another layer of defense to the thin defensive shield.

It can withstand the scorching heat.

Du Yun was surprised. The richness of the flames in this place made his heart move. Could this be the place where the fire element exists?

Shaking his head, Du Yun thought about it and thought it was impossible. Although the flames here were strong, there was still a gap compared to the thunder pond under the Yingchou Cliff in the back hill of the Du family.

From this comparison, Du Yun immediately understood that there must be no fire element here. At that time, when Du Yun saw the thunder and lightning at the thunder pond under Yingchou Cliff, he did not dare to approach it at all. He only dared to enter after the thunder and lightning disappeared.

Thunder pool quenching body.

Although his current strength is much stronger than before, he doesn't believe that there is a fire element here.

At that time, he was able to absorb the thunder element because his body was already immune to thunder and lightning, so he could easily absorb the heart of thunder. According to Du Yun's current thinking, this heart of thunder should be the source of the thunder attribute.

Because after he absorbed the Heart of Thunder, the power of the thunder pool was obviously reduced by one level. Moreover, his strength increased sharply. The people of the Du family must have doubts, and a search was inevitable for the bottom of Yingchou Cliff.

Just thinking about their fruitless search, Du Yun sneered in his heart. Although he was born in the Du family, except for Du Ping, there was no feeling of blood connection with any other Du family in his heart.

"I just don't know what is in the secret room that Lin Yifei talked about?" Du Yun was shocked and confused, but at this point, he was unwilling to back down.

One hour is approaching soon. It is obvious that the expressions of Lin Yifei and the others have become more solemn. And the flames in this area are beating automatically without any wind.

"Kick! Kick! Kick!"

Almost ten minutes later, not far in front of Lin Yifei and the other three, there was suddenly a violent sound of earth shaking. The sound was soul-stirring and seemed to have magic power, making people's hearts beat faster.

"Roar!"
