As soon as he arrived at the entrance of the cave, a heat wave suddenly hit, and at the same time, in this heat wave, there was an extremely strong evil qi, and Lu Bu couldn't help frowning slightly. This evil aura, even though it is far away, is still so strong, which shows how fierce the things in this cave are.

Lighting the torches, Lu Bu and Long Fei walked into this dark molten cave.

It was pitch black all around, and the limited light of the torches could only illuminate a small part of the scene, and the atmosphere suddenly became oppressive. After a pause, Lu Bu suddenly asked, "That eldest lady, who is it?"

Long Fei sighed and said helplessly: "She is the daughter of Chuzhou Mu Sun Qing, Sun Yunsheng. ”

Lu Bu was stunned in his heart, he couldn't imagine that this unruly girl would have such a big background, but Long Fei, as the person who came here to investigate, was also extraordinary, so Lu Bu asked at the moment: "Your Excellency can come to investigate this dangerous place alone, you must have the courage to come, I don't know what sect you are?"

"Hah! You can see this, and you really have a vision. Long Fei raised his chin and said proudly: "I am the first person in Chuzhou, and I am known as a martial arts genius once in five hundred years. ”

Lu Bu looked at Long Fei a little speechlessly, only to feel that to a certain extent, he and that Sun Yunshang were really the same as making people speechless.

"At that time, I was in the sect for 100 days of special training, so I couldn't catch up with the competition of martial arts in the world, otherwise, I dare not say more, and it is no problem to get the top four. Long Fei said to himself.

Lu Bu chuckled, only to feel that he was quite confident in his martial arts, and his strength must be very strong.

"This time, Lord Sun Qing personally dispatched me from the sect to investigate this matter, as long as I complete this mission, I will be the true disciple of the sect. Speaking of this, Long Fei's eyes were full of expectation, this point, Lu Bu empathized with him, the true disciple is not only a symbol of status and future, the most important thing is to be able to be personally taught by the legendary master, and this is the most valuable wealth.

Walking into the dark cave, the temperature in this cave became higher and higher as the two of them went deeper. Long Fei began to slowly run his True Qi to resist the blazing heat.

As he continued to go deeper, Lu Bu's face became more and more solemn, and at this moment he could clearly perceive the fierce thing hidden in the depths.

Long Fei, who was beside him, also had a solemn face at the moment, he tightened the machete behind his back and continued to walk forward. Finally, after walking through this passage, there was a fiery red in front of me.

This is like a lava cave hall in an underground magma world, in this huge crypt, a large area is oozing with fiery red magma, like a river flowing slowly, huge bubbles continue to emerge from the magma, and then with a bang, burst.

Standing at the entrance of this cave, Lu Bu and Long Fei looked at the magma hall that was almost impossible to see, and they were only extremely shocked in their hearts. Huge stone pillars and rock walls support this world, and on top of these rock walls, there are countless glittering crystals, dotted like stars.

"If I'm not mistaken, these spars that glow red should be fire refining spars!" Lu Bu muttered as he looked at the stone pillar and the spar above his head.

"Yes, these are fire refining spars, but what I didn't expect was that there were so many of them!" Long Fei couldn't suppress the excitement in his heart, this discovery was not a big one.

"Don't be happy yet, there is a guy hidden in this cave that is not easy to mess with!" Lu Bu's eyes locked on the magma, and at this moment, he could clearly perceive that an extremely vicious thing was here.

Suddenly, a huge magma bubble burst open, Long Fei's brows furrowed, he pulled out the machete behind him, his hands clenched, and his expression was grim.

"There's living creatures down here. Long Fei's eyes were fixed on the place where the huge bubble burst, and it was unbelievable that he could survive in this hot magma.

A strong scorching breath spread, and under the calm magma, there was a muffled sound, and a huge mysterious creature wrapped in the blazing magma suddenly rushed towards Lu Bu and Long Fei.

With a "boom", the creature hit its head at the entrance of the cave, and suddenly the entire lava cave shook violently, and countless rubble continued to fall, splashing the fiery red magma into one magma wave after another.

In the hall of the lava cave, Lu Bu and Long Fei scattered left and right, and the true qi of their whole bodies was running to the extreme in an instant, looking at such a huge mysterious creature, they did not dare to take it lightly.

With the violent impact just now, this huge mysterious creature immediately faded away from the hot magma, revealing its original dignity.

This is a huge snake-like creature, the body is extremely long, a cursory look, no less than thirty meters, the triangular burning flame of the huge snake head, slowly raised, only this snake head, there are three people in size, the pair of eyes like two burning flames, is even more fierce, extremely hideous.

"What is this?" Lu Bu's whole body was full of orange, and a substantial light instantly condensed out.

"Could it be ......" Long Fei swallowed his saliva and muttered, "The legendary ancient beast - the Flame Spirit Snake!"

Before the words fell, the flame spirit snake's huge mouth opened wide, and a blazing flame spat out, blasting towards Long Fei fiercely.

With a "bang", Long Fei jumped, and the blazing flames swept under his feet, shattering the ground he was originally standing on at the moment of impact.

Feeling this blazing heat, Long Fei was furious in his heart, and the muscles of his whole body suddenly swelled, and a violent momentum, mixed with the fierce thunder and lightning, burst out in the air.

"Don't be too arrogant to Lao Tzu!" Long Fei roared angrily, above his arms, purple qi came out of his body, and even with the machete in his hand, it was also purple mang, looking at the huge snake head, Long Fei raised the machete in his hand and slashed at the snake head.

With a "boom", the purple glittering machete slashed heavily on the snake's head, and suddenly the air was cracked, and the fire burning above the head of the flame spirit snake suddenly dispersed from it, and a stream of red and viscous magma splattered out like blood, falling on Long Fei's body, blocked by the thunder and lightning armor that condensed his whole body, making a hissing sound.

However, before he could be proud, the huge snake tail shook over unexpectedly, and immediately knotted Long Fei with a strong knot, and his whole body flew out directly, and then slammed into the rock wall behind him, knocking it out of a big hole.

Just when the flame spirit snake was about to take advantage of the victory to pursue, Lu Bu's figure had already rushed over, and in an instant, Lu Bu and the flame spirit snake looked at each other, the orange mang's Fang Tian painting halberd, with unrivaled fierce energy, this blow was actually an instant condensation of the Chongxuan Sect's highest stunt Tiangang Slash.

At the beginning, he had no reservations and struck with all his might, and at this moment, even if it was an ancient fierce beast flame spirit snake, he couldn't help but show a trace of panic in his eyes. However, even though it wanted to dodge, the invisible imprisoning force hindered its movement.

In the next moment, Lu Bu let out a low shout, and the Fang Tian Painting Halberd smashed into the head of the Flame Spirit Snake with an incomparable fierce energy, and in an instant, there was a loud bang, like thunder in the sky, and a domineering energy ripple suddenly spread out, and the entire lava cave hall trembled violently.

Countless rubble fell, and the huge figure with a fiery red body was smashed into the magma, stirring up huge magma waves that spread like mountains and seas.

With one blow, the flame spirit snake was directly smashed back into the magma, and there was no movement in the middle of the sound.

With a "bang", Long Fei rushed out of a pile of rubble, just now Lu Bu's full blow, he really saw it, this Tiangang slash that can increase the power exponentially, it is really overwhelming.

It's just that the flame spirit snake that was knocked back into the magma didn't make the slightest movement, and the entire magma pool was already quiet. However, the fierce and evil aura has always surrounded it and has not dissipated. Lu Bu and Long Fei knew very well that this flame spirit snake would inevitably launch another onslaught at the two of them.

Without taking it lightly, Lu Bu and Long Fei held their breath and concentrated on it. Suddenly, the flame spirit snake rushed out of the magma again, and the speed was as fast as an arrow off the string, shooting out towards Lu Bu and the others. However, the two, who had already had a premonition, dodged calmly again.

At this moment, the whole body of the flame spirit snake was lit with raging fire, as if the god of fire had descended, and its power was amazing. The blazing heat on his body, even though they were separated by a certain distance, Lu Bu and Long Fei could still feel a scorching heat.

"Let's go together!" Long Fei raised the corners of his mouth slightly, and said excitedly, in the face of such a powerful existence, Long Fei's battle intent was also like a raging fire, quickly ignited.

The next moment, Long Fei took the lead, and his figure burst out like a lightning blast. In the activated state of thunder and lightning, Long Fei's speed was unusually fast, and before the fast flame spirit snake could react, it was stabbed into the snake's belly by Long Fei.

However, at this moment, the violent high temperature melted the machete into a pile of molten iron in an instant, and Long Fei was in a hurry to let go, but the magma-like blood still splashed on Long Fei's body, and the solid thunder and lightning armor was burned out of a big hole in an instant, and then mercilessly burned his right chest with a huge scar.

Another sweep of the tail, with the raging fire, Long Fei covered his chest with his right hand, and he didn't have time to react at all.

The blazing heat carried that fierce energy, and even with Long Fei's violent body, he would definitely be hit hard. However, at this moment, a seven-colored light burst out, firmly blocking Long Fei's body.
