"What's the situation?"

The half-demon and Hasser were confused, completely unaware of what was going on. But when they saw Frankenstein next to them also start running wildly, they immediately ran as well.

Under the light footwork bonus of rising to the third level, Zhang Luo's movement speed was no slower than the three monsters behind him, and it only took a minute to soar nearly a thousand meters.

Still, there was no boundless darkness in front of him, and he immediately realized that the road was much longer than he had imagined.

"Damn, run out of time?"

Seeing that the time had reached twelve o'clock, and there were less than two minutes left before the time written in the notebook, Zhang Luo bent down slightly, lowered his body, and continued to sprint forward at a faster speed than just now!

After fusing demonic blood in his body, his physical fitness was a notch higher than before, and the explosive power of his legs was not at all comparable to before.

However, in the state of "full fire", the consumption of physical strength is also much greater than usual. Less than a minute later, he was already running out of breath.

At this time, at the end of the dark tunnel, a "light of hope" finally appeared.

It was a stone wall in front of it, which looked like it had completely blocked the tunnel, and unlike the smooth walls, this one was potholed, a bit like an artificial stone wall for beginners.

Seeing this stone wall, Zhang Luo didn't say a word, rushed over with a hungry tiger-like action, directly grabbed a dent on the stone wall, and the whole person was almost attached to the cold stone wall.

Seeing what he did, the other three immediately imitated his movements and leaned against the stone wall. And then......

"Buzz!"

A faint tingling pain burst out from his brain, Zhang Luo's hearing was suddenly swallowed up by the sound of tinnitus, and his body, which was originally leaning on the stone wall, actually "fell" in the direction of the top of the cave under the drive of gravity.

"It's ...... Is gravity reversed? The half-demon man's voice was filled with irrepressible surprise.

Zhang Luo, who was originally at the bottom of the cave, suddenly became in a state of hanging on the "edge of the cliff", but fortunately he grasped a depression in the cave wall in time, otherwise he would have "fallen" directly.

"There's big machines working." Frankenstein, who was hanging next to him, whispered.

After the brief tinnitus disappeared, Zhang Luo could finally hear her words, and nodded: "That's why those four people will die on the top of the cave." ”

- Obviously, the poor expedition team must have strayed into this mysterious cave by accident, and then while looking for a way out, they happened to encounter this terrible gravity reversal, and all of them fell to their deaths on the roof of the cave.

However, if it was just a simple gravity reversal, then their corpses should not be embedded in the stone wall at the top of the cave......

Thinking of this, Zhang Luo noticed that the weight of his body seemed to be a little larger than before.

"Do you feel like you're getting heavier?" He turned to Frankenstein beside him.

"Hmm."

At the same time, the girl in the black combat uniform had already let go of her hands and fell towards the top of the cave!

"Boom!"

There was a loud bang, the smoke was filled, and the impact caused by the moment the "girl" with a body weighing one ton landed on the ground, shaking the entire cave as if it were trembling slightly.

Seeing her jump, the half-demons and Hassin, who were hanging on either side of the cave, glanced at each other, and let go of their grips on the stone wall.

"It's really ...... convinced"

Although he wanted to imitate the movements of these guys, Zhang Luo knew that with his human body, he could jump directly from a height of more than ten meters, and even if he didn't fall to death, he could only end up crippled, so he could only "climb up" slowly......

It took a minute to climb to the top of the cave, and after his feet landed on the top of the cave, Zhang Luo patted the dust on his hands and looked around with the aperture of the flashlight.

His current state is like hanging upside down on the roof of the cave. Even if you jump hard, you just fall back to the top of the cave again.

"Let's get out of here." He said.

If it was just in an upside-down state, what worried him even more was that the gravity in this cave was not only changing direction, but also increasing at an extremely fast speed.

- I had only been standing on the top of the cave for less than a minute, and my legs were much heavier. The strong force of gravity directly negates the effect of the "Light Footwork" skill. If you stay a little longer, you will probably be crushed into the rocks like the corpses of the four explorers!

"There's an exit over there." Frankenstein raised his small hand and pointed to the stone wall behind Zhang Luo's side.

It was a rectangular gap, about two meters high and one meter wide, and just looking at the incomparably standard outline, you knew that it could not be a "miracle of nature", but was built.

With no other way to go, the four "adventurers" made a decisive decision and walked towards the gap that led to the back of the stone wall.

Walking through the narrow gap, there was a feeling of sudden enlightenment, and when he saw the scene in front of him, even Zhang Luo, who had seen all kinds of strange events in these days, thought that he would not be surprised anymore, couldn't help but exclaim:

"I'll go, this one is really handsome......"

What they entered this time was a huge underground "cavity", more than ten times wider than the tunnel just now.

This time, the giant cave is not like the cave just now, and on the arc-shaped wall, a mysterious light blue fluorescence lights up, illuminating everyone's sight.

The first thing that comes to mind is a cone-shaped building made of earthy yellow boulders, casting a huge triangular shadow under the light of the blue light.

Just seeing that majestic appearance, a huge sense of awe rose from Zhang Luo's chest.

There is no doubt that this building is familiar to mankind all over the world - the giant pyramid!

As a member of the "Eight Wonders of the Ancient World" and one of the most astonishing architectural achievements of antiquity, the Egyptian pyramids are a famous tourist attraction and a topic of conversation even today.

These cone-shaped buildings with spires were used as tombs for the pharaohs of ancient Egypt. It is widely accepted that the pyramid was built over a long period of time by a large number of workers, and that it embodies the exquisite craftsmanship and technology of the "ancient working people".

However, that theory was only established when the underground pyramid had not been discovered. Because-

"Oh my God, is this pyramid hanging upside down in the ground......"

Seeing the scene in front of him, the half-demon thought that he was hallucinating, and immediately reached out and rubbed his eyes.

In the case of gravity reversal, the four people are still standing on the top of the cave, and the "ordinary pyramids" they see from their perspective are obviously not the same as those pyramids on the ground.

That is, this miracle building, made of huge stones and at least a hundred meters high. It was hanging upside down in an underground cave!

Shocked by the amazing scene in front of her, the bronze-skinned Egyptian royal sister also froze in place in shock. Frankenstein, on the other hand, immediately opened the storage space, took out a strange-looking black "camera" and began to shoot.

“……”

Zhang Luo clenched his fists slightly, and a flame of excitement seemed to ignite in his chest.

This underground structure, which will immediately subvert existing theories as soon as it is made public, should not have been built by humans. Other words......

"Let's see what's inside, shall we?" As he spoke, he began to walk towards the magnificent building in front of him.

Because of being too excited, the voice of this strange talk lover was trembling slightly.
