"Let's go."

The Invincible Fist Saint took away the flames on his body, and it looked ordinary. Who would have thought that the phantom of the terrifying flame giant that was like a god just now was the power that the Invincible Fist Saint burst out?

Every saint is extraordinary, far surpassing the super god warrior.

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

The true saint, Lin Feng has never seen the saint burst out with all his strength. Now, the power displayed by the Invincible Fist Saint is simply earth-shaking, which shocks Lin Feng deeply.

If you can smash such a big hole in one go, just by looking at power, Lin Feng has to use a battle body of at least two hundred meters.

Therefore, Lin Feng also put away his contempt for the saints. Perhaps the saints do not have a cosmic cultivation system or a war body, but the martial arts system cultivated by the saints is a practice that is tempered by humans and has been continuously improved over generations. The final form of a more suitable practice method is naturally unique.

"Walk!"

The Invincible Fist Saint took Lin Feng and jumped directly from the deep and dark hole. The inside was filled with wind, and it was a little cold. It was very dark, and there was no five fingers in both hands.

However, both Lin Feng and the Invincible Fist Saint can achieve night vision, and this dark hole has no impact on them.

The big hole seemed to be straight down, like an abyss. The two of them didn't know how long they had fallen down. Slowly, there was a little wet feeling below, but it was on the ground.

After Lin Feng fell to the bottom of the cave, he looked up and could only see a beam of light, like starlight, but he could not see the entrance of the cave at all, which shows how deep the cave is.

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

"The Sixth Grotto? Didn't we come in from the First Grotto?"

Lin Feng was a little surprised.

"Hehe, there are eighteen caves under the ground. After so many years, the marks made have disappeared. Who can remember the order of these caves? Every time I want to enter Longtou Eighteen Caves, I will directly smash a big hole and jump in, and there will naturally be some deviation. Fortunately, it is just the sixth cave, and there is no deviation too far."

Lin Feng didn't know what to say, this was a forbidden area. The Invincible Fist Saint seemed, well, he was a little too hearted...

But no matter what, they have entered the grottoes.

The grottoes are bare and collapsed stones are everywhere, but some murals can be vaguely seen on the walls. Although they are old and look very mottled, some of them can be seen vaguely.

None of these murals are written on them, they are all strange paintings, such as some terrible monsters with six heads and twelve arms.

There are also human-headed centipede bodies and some charming goddesses.

These murals are full of a strong mythological color.

"Aren't these some religious places in ancient times our humans?"

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

"No, I entered the cave before and saw these murals. I even took some photos to go back to study for some historians. They unanimously determined that this is by no means a religious mural from ancient humans!"

"And you may be surprised by the identification of some rock elements on the murals. These rocks have a history of more than 300 million years!"

Lin Feng was shocked. Humans have not appeared for 300 million years. After all, human civilization has only been a few thousand years. Even if humans have appeared, it has only been a few million years.

It is impossible to have a history of 300 million years.

Unless, this is left by ancient civilizations.

"Ancient civilization?"

Lin Feng narrowed his eyes slightly. He had seen the third and seventh civilizations, both of which were technological civilizations. As for other civilizations, he had never seen them.

"Yes, according to our calculations, this should be a ruin left by an ancient civilization. Moreover, there are no traces of technology in the caves, which means that this is not a science and technology civilization. It is often more dangerous, so we have to be careful."

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

The grottoes are very tidal, and I don’t know what’s going on. They are not only wet, but also very stuffy.

Following the murals in the cave, Lin Feng and the Invincible Fist Saint slowly walked forward. Suddenly, the front suddenly became clear and a huge hall appeared.

There is an altar in the hall, and thick stone pillars, and some stone chairs under it, but they all disappeared because of the air drying. The entire hall has an ancient and desolate feeling.

"Rumbling".

Suddenly, the cave started to shake violently again, the earth was shaking, and the cave seemed to collapse.

"The source of the vibration is still below."

The Invincible Fist Saint immediately felt that the source of the vibration should not be in the Sixth Grottoes, but it was still a little further below, and it was still a little further away from the Sixth Grottoes.

However, the vibration became more and more intense, and suddenly, a strange stone sculpture on the altar fell down.

"Bang".

The stone sculpture was broken, and black beetles crawled out from it. What's even more strange is that the black beetles also had blood-red patterns on them.

"call……"

These black beetles almost grew in the wind. After a few breaths, they had grown to the size of a baby one or two years old, and looked very ferocious and terrifying.

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

These black beetles flew directly towards Lin Feng and the Invincible Fist Saint. When the Invincible Fist Saint reached out and a ball of flame flew out, wrapping dozens of beetles and burning.

"Squeak squeak".

"Hey, can't be burned to death?"

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

But how could the Invincible Fist Saint be just flame?

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

"boom".

The earth was shaking, and a big pit was photographed on the ground. The black beetles photographed had turned into a mass of flesh and blood.

Lin Feng did not slap these beetles to death. His body suddenly swelled and instantly turned to more than ten meters high. Then he grabbed all the beetles with his hands.

“It is corrosive and toxic.”

Lin Feng felt that the war body was damaged. Although it was very rare, it was indeed damaged. These beetles were highly toxic.

He was no longer polite, and he easily pinched the beetles to death with just a pinch.

"Rumbling".

At the same time, an even more shocking scene appeared. The tall and strange sculptures around the altar seemed to be touched, and they began to emit green light, as if they had "come alive", and quickly turned into ferocious monsters, staring at Lin Feng and the Invincible Fist Saint.
