"Let's go. ”

The Invincible Fist Saint collected the flames on his body, it looked unremarkable, who would have thought that the terrifying flame giant phantom like a god just now was the power of the Invincible Fist Saint to burst out?

Every Sage is extraordinary, far surpassing the Transcendent Martial Artists.

Originally, Lin Feng had a tidal battle body, and he had even fought with the Guardian, and he felt that the Sage's combat power was nothing more than that. But that's just the Sage's combat power, not the real Sage.

The real Sage, Lin Feng had actually never seen the Sage burst out with all his might, and now, the power exerted by the Invincible Fist Saint was simply earth-shattering, which made Lin Feng deeply shocked.

To be able to smash such a big hole at once, purely from the perspective of strength, Lin Feng would have to show a battle body of at least two hundred meters or more.

Therefore, Lin Feng also put away his contempt for the sages, maybe the sages don't have a cosmic cultivation system, and they don't have a battle body, but the martial arts system cultivated by the sages is a cultivation method that is more suitable for human beings after being tempered by thousands of human beings, and after continuous improvement from generation to generation, it naturally has its own uniqueness.

"Let's go!"

The Invincible Fist Saint took Lin Feng and jumped directly into the deep and dark hole, which was cloudy and windy, and it was faintly cold. And it's very dark, and you don't see your fingers on your hands.

However, whether it was Lin Feng or the Invincible Fist Saint, they could see at night, and this pitch-black hole had no effect on them.

The big hole seemed to go straight down, like an abyss, and the two of them didn't know how long it had been down, slowly, there was a little damp feeling below, but it was ground.

After Lin Feng descended to the bottom of the cave, he looked up, and could only vaguely see a beam of light, like starlight, but he couldn't see the entrance of the cave at all, which showed how deep this big hole was.

"Be careful, this is probably the Sixth Grotto. ”

"Sixth Grotto, didn't we come in from the First Grotto?"

Lin Feng was a little surprised.

"Hehe, there are eighteen grottoes underground, after so many years, the marks have disappeared, who can remember the order of these grottoes? Every time I want to enter the eighteen grottoes of Longtou, I just smash out a big hole, and then jump in, naturally there will be some deviations. But fortunately, it's only the sixth grotto, and there is not too far to deviate. ”

Lin Feng didn't know what to say, this was a forbidden place, the Invincible Fist Saint seemed to be, well, some hearts were too big......

Either way, they had entered the grotto.

The grotto is bare, full of collapsed stones, but some frescoes can be faintly seen on the walls, although they are very old and look very mottled, but some of them can be faintly seen.

There are no words on these murals, and they are all strange paintings, such as some terrible beasts with six heads and twelve arms.

There is also a centipede body with a human head, as well as some seductive goddesses.

These murals are imbued with a strong sense of mythology.

"Isn't this some of our ancient religious sites?"

Lin Feng was a little surprised, these murals must have been painted by someone, and they had such a strong mythological color.

"No, I have entered the grotto before, I have seen these murals, and even took some photos to study back to some historians, and they unanimously concluded that this is by no means our ancient human religious murals!"

"And through the identification of some rock elements on the mural, you may be surprised by the identification age, these rocks are probably more than 300 million years old!"

Lin Feng was shocked in his heart, for 300 million years, human beings have not appeared, after all, human civilization is only a few thousand years, even if you count the time when human beings appeared, it is only a few million years.

It can't be 300 million years old.

Unless, this is what was left over from ancient civilizations.

"Ancient civilizations?"

Lin Feng's eyes narrowed slightly, he had already seen the third civilization and the seventh civilization, all of which were scientific and technological civilizations. As for other civilizations, he really hadn't seen them.

"Yes, according to our calculations, this should be a relic of an ancient civilization. Moreover, there are no traces of science and technology in the grotto, which shows that this is not a scientific and technological civilization. It's not a technological civilization, but it's often more dangerous, and we have to be careful. ”

The Invincible Fist Saint looked very cautious, and the two slowly walked towards the depths of the grotto.

Inside the grotto it was very tidal and I don't know how, not only was it humid, but it was also very muggy.

Following the murals in the grotto, Lin Feng and the Invincible Fist Saint slowly walked forward, and suddenly, a huge hall suddenly opened up in front of them.

There was an altar in the hall, and there were thick stone pillars, and some stone chairs underneath, but they were all lost because of the drying, and the whole hall had an ancient, desolate feeling.

"Boom".

Suddenly, the grotto shook violently, the ground shook, and the grotto seemed to be collapsing.

"The source of the shaking is still down there. ”

The Invincible Fist Saint immediately felt that the source of the vibration should not be in the Sixth Grotto, but even below, and there was still some distance from the Sixth Grotto.

However, the shaking became more and more violent, and suddenly, a strange stone sculpture on the altar fell.

"Bang".

The stone carving was shattered, and black beetles crawled out of it, and what was even more strange was that the black beetles had blood-red patterns on their bodies.

"Hoo ......"

These black beetles grow almost in the wind, and in a few breaths, they have grown to the size of a baby of one or two years old, and they look very hideous and terrifying.

"Be careful, don't let them get close!"

These black beetles flew directly towards Lin Feng and the Invincible Fist Saint, and as soon as the Invincible Fist Saint stretched out his hand, a ball of flame flew out, enveloping dozens of beetles and burning fiercely.

"Squeak squeak".

"Hey, can't you burn?"

The Invincible Fist Saint was a little surprised, these beetles actually rushed out of the encirclement of the flames, and flew towards the Invincible Fist Saint frantically, as if they were not afraid of the flames.

But is the invincible Fist Master just a flame?

He stretched out his big hand, and the infinite star power quickly converged, and he slapped it directly.

"Boom".

The ground shook, a big pit was photographed on the ground, and the black beetles that were photographed had all turned into a mass of flesh and blood.

Lin Feng didn't slap these beetles to death, his body swelled violently, instantly turning into more than ten meters high, and then grabbed them all in his hands with a big hand.

"It's corrosive and highly toxic. ”

Lin Feng felt that the battle body was damaged, although it was very rare, it was indeed damaged, these beetles were highly poisonous.

He was no longer polite, and with a pinch of his hand, he easily pinched these beetles to death.

"Boom".

At the same time, an even more shocking scene appeared, the tall and strange sculptures around the altar seemed to have been touched, and they began to emit cyan light one by one, as if they had "come to life", and quickly changed into fierce monsters, staring at Lin Feng and the Invincible Fist Saint with fierce eyes.
