"Lei Long, do you really think I'm afraid of you?"

A cold light flashed in her hand, and a two-inch-wide sword appeared. Her sword swept out with a wind, and a phoenix shadow appeared in the air. With a long whistle, the shadow shot out towards the black lightning that filled the sky.

That was … An earth-step treasure!

Although Chu Fei had never seen such a treasure before, just from the strong energy that it gave off, he could tell that it was an Earth Ranked or higher treasure. In the entire Mysterious Sky Academy, there was not a single such treasure!

From the looks of it, the reason why the two of them were fighting was for the blood of the Thunder Dragon. However, he didn't know why the woman in red wanted half of the Thunder Dragon's blood. It was possible. With the Blood of the Thunder Dragon's strength, it could also speed up the Vermillion Bird's evolution.

"What the f * * k …" If I could just take a sip of the Thunder Dragon's blood, even a tiny bit, for the rest of my life. It's also worth it! "

Hearing the annoying voice of the Haemagglutinoma sacri, Chu Fei silently rolled his eyes in his heart. Was this guy addicted to blood again? If you want to suck it in, go right now. It's currently fighting someone, so it shouldn't notice you. "

"What a joke. With my current strength, I might not even be able to pierce through its skin and be smacked into smithereens …"

"You know your own limits."

"Of course. Not only do I have self-awareness, I also have foresight. Just you wait and see. Your future blood will be much better than this Thunder Dragon's!"

"What do you mean?"

Chu Fei immediately retracted his gaze, and asked Haemagglutinoma sacri with an unfriendly expression. Was he trying to kill him? Why did he feel like he had become a mobile blood bank?

"Hehehe …" I'm praising you, do you know that? Your future achievements will definitely be better than this lightning dragon! "

"I can't be bothered with you."

Chu Fei continued to watch the battle in the air. This was a battle between two experts, he did not want to miss any of the details, but he had to be wary of this Haemagglutinoma sacri, if it dared to make even the slightest movement, he would directly kill it!

Chu Fei also had his own thoughts as he watched the fierce battle between man and dragon unblinkingly. Battles between experts were the most frequent, especially when he could gain some inspiration from it, maybe it would be of help to his martial arts. Naturally, he couldn't miss it at all.

"Rise!"

With a wave of her long sword, a scarlet red light shot up into the sky. The streaks of flame interweaved around the woman in red, and even the dense black lightning in the sky was shattered by the flames. The flames burned brighter and brighter, directly forming a gigantic vortex of fire in the air!

As the power of fire grew increasingly intense, the Thunder Dragon's expression became increasingly grim. In mid-air, it let out a furious roar.

Following that, Chu Fei noticed that the dozens of Pyroxine on the Thunder Dragon's body all roared out together, and then, their mouths opened wide as countless balls of lightning rushed up to the sky. The balls of lightning gathered together, and the ball of lightning became bigger and bigger, the power of lightning also became denser and denser, following that, the Thunder Dragon opened its mouth and inhaled …

Amidst Chu Fei's astonished gaze, the lightning dragon forcefully sucked all the lightning balls into its body, and the black lightning on its body instantly increased dramatically. It was originally only as thick as a thumb, but now it instantly became as thick as an arm.

This lightning dragon … Did he really want to kill the woman in red?

Chu Fei could see clearly from the side that the two of them had already fought before, but the lady in red seemed to have lost. Now, it seemed that the lightning dragon was borrowing its own subordinate's help to fight against the lady in red.

When Chu Fei looked at the red-clothed girl again, his eyes were already filled with shock. He never thought that this girl would look so young, but her strength was actually so terrifying, even far stronger than what he had imagined. He thought that he was a genius, but he never thought that he would be so weak when compared to these genuine peerless geniuses.

"Go..."

Even Chu Fei was extremely apprehensive of the power of the lightning. After a few minutes of the deadlock, the lady in red brandished her sword indifferently, and the scarlet red vortex of flame ruthlessly shot towards the Thunder Dragon. Not only towards the Thunder Dragon, but also towards the subordinates behind it!

The red-clothed female also knew that the lightning dragons and these Pyroxine were complementary to each other.

Roar! Roar! Roar!

Sensing the incoming danger, the Thunder Lizard didn't dare to delay any longer. It immediately roared and pushed its claws forward. A huge black lightning ball ferociously shot towards the lady in red.

Lightning and fire instantly interweaved, and a blinding light flooded the entire sky.

BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOM!

The instant the explosion occurred, an intense wave of energy undulations exploded into the sky. Chu Fei could feel the entire thundercloud peak trembling, and even the village at the foot of the mountain could feel the shocking undulation.

After the explosion, the scarlet flames did not dissipate, instead, bits of the flames fell like meteorites and fiercely smashed into the Pyroxine s that were on the ground. Immediately, a few Pyroxine s were sent flying and fell to the ground with serious injuries.

Unexpectedly... So terrifying!

Chu Fei who had seen all of this had shock written all over his face. He never thought that the red clothed lady's fire attack, even after being scattered by the electric ball, would still have such a powerful might. If it was a direct confrontation, how powerful would it be? If it was him, he probably wouldn't even have the strength to fight his enemy and would have been instantly killed.

Crack! Crack! Crack!

Just as Chu Fei was reeling in shock at the power of the shockwave, suddenly, a few cracks sounded beside his ear, and then, he turned his head to look, only to realize that the Pyroxine had smashed a part of the mountain wall. Behind the mountain wall, there was actually a gloomy cave, which was extremely similar to the cave of the Pyroxine he had previously discovered.

Could it be... This should be the Thunder Dragon's lair, right?

Chu Fei suddenly had a wild guess in his heart. This was the summit of the thundercloud peak, and with the Pyroxine's absolute control over their territory, it was impossible for other Pyroxine to exist here. Furthermore, other than the lightning dragon, he couldn't think of anyone else that would dare to live in such an excellent place.

"Chu Fei... If it really is the Thunder Dragon's lair, then we … But it really did happen! "

The Haemagglutinoma sacri also saw the existence of the cave. The injured Pyroxine had already flown away, and were rushing towards the "front line", where the back area of the Pyroxine was empty. If they could seize this good opportunity, they would really grow big!

The Haemagglutinoma sacri's words also somehow ignited a fire in Chu Fei's already restless heart. Last time, he found a Thousand Thunder Vine in the Pyroxine's cave, then as the absolute boss of the Pyroxine, wouldn't there be more heavenly materials for the Thunder Dragon's nest?

Do you want to … Try it?

Chu Fei's heart started to feel itchy, and when he saw the ten odd Pyroxine s that were not too far away from the cave entrance, he started to feel like retreating. Even if one of them was paying full attention to the front lines, as long as one of them discovers that there was some movement from behind and with their strength, if they tried to make a move on him, he would really be dead for sure!

"Motherf * cker! Wealth comes only from danger! What are you trying to do? Go all out!"

Chu Fei thought for a long time before finally clenching his teeth! At this time, there was still the red-clothed female who could hold the attention of these Pyroxine. This kind of opportunity might come with an exception, and if he really missed it, even if he broke through to the Postnatal realm in the future, it would be impossible for him to break into the Pyroxine's lair.

It was going all out, so what?!

Seeing the disparity between him and the lady in red, Chu Fei was also deeply provoked. There really is a sky above the heavens, there is always someone beyond the human world, if he wanted to reach a higher realm, he would have to fight for it! On the road of martial cultivation, he dared to fight for his life with the heavens. With great difficulty, he finally got such a rare opportunity. No matter what, he could not miss it.

As he turned his head to take a deep look at the brilliant battle in the sky, Chu Fei silently selected a set of grey clothes from the Illusory Sky Ring. In this place, there were Thunder Stones everywhere, but the grey clothes had unknowingly formed a protective layer.

BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!

The battle in the sky became even more intense, and all the Pyroxine were completely focused on the battle above. No one would have thought that a tiny human would sneak into the peak of thundercloud peak, and even dare to enter the Thunder Dragon's nest!

Hurry, hurry, hurry!

At this time, Chu Fei's ears could no longer hear the sounds of the battle in the air, he could only hear the intense thumping sounds of his own heart, and only a single word remained in his head, which was fast, quick, fast! He had to quickly enter the cave before the Pyroxine realized this.

Closer and closer …

Chu Fei's eyes instantly widened to the extreme. Seeing that the distance between him and the cave was only a hundred meters, with his movement technique, he could reach the cave in the blink of an eye. Just as Chu Fei was about to enter the cave, a rumbling sound suddenly came out!

He only saw a huge Pyroxine being blasted away by the flames, smashing straight into the cave entrance. The distance between man and beast was so close, Chu Fei could even clearly see the blood gushing out from the large mouth of the Pyroxine!
