As soon as the stone door vibrated, the ten people standing in front of the stone door immediately retreated and stayed far away.
Before the stone door opened, the hundreds of cultivators here were still thinking of charging in as soon as the stone door opened.
But now, they all retreated as if there was some powerful mutated beast behind the stone door.
Amidst the intense vibrations, the stone door slowly sank.
A few minutes later, a crack finally appeared at the top. Intense light shone out from within.
Light always made people feel at ease. Seeing the bright light shining out from within, the cultivators could not help but heave a sigh of relief.
At this moment, everyone began to look forward to it.
In the universe, there was no lack of wealth left behind by the previous generations. Most of them existed in various corners of the universe. Some existed on planets, some in meteorites, some in the stars … There were many ways to exist.
However, the powerhouses who possessed these riches did not want their descendants to obtain them so easily. Therefore, before they died, they would create such a secret realm and leave behind their riches.
These secret realms were not only difficult to find, but they were also equipped with various mechanisms.
These mechanisms were, of course, very powerful because they were also a way to display intelligence.
The riches left behind by the powerhouses were mostly used by the cultivators to cultivate. There were all kinds of rare energy, such as Stellar Crystals and Beast Cores.
There were also some armors and weapons …
What was in this palace?
Before the stone door opened completely, the cultivators guessed.
Under the gaze of hundreds of people, the stone door finally sank completely into the ground. The situation behind the stone door also appeared before the eyes of the cultivators.
Behind the stone door was a passage about ten meters wide. Although it was bright, they could not see the end. The bright light was released by some glowing spots at the top.
Seeing this passage, all the cultivators widened their eyes.
The few cultivators standing at the front rushed in first.
"Roar!"
As soon as these cultivators rushed in, a beastly roar could be heard from inside.
Hearing this beastly roar, the cultivators could not help but feel their hearts skip a beat.
Indeed, there was a price to pay in order to obtain benefits.
The cultivators who rushed in immediately retreated and left the passage.
"Boom … Boom … Boom …"
The ground suddenly started shaking, sounding very rhythmic. It should be the sound of a heavy exotic beast walking on the ground.
At the same time, a powerful energy wave spread out from inside.
A Star-domain Lord-class alien beast!
This strange beast had yet to appear in their line of sight, but the cultivators had already determined its level.
The several hundred cultivators became nervous. They gripped their weapons tighter and tighter as they slowly retreated.
Some people, especially the cultivators who had fought with the giant beast, retreated to the entrance of the passageway they had come from.
"Boom boom boom boom …"
All of a sudden, stone doors that were several feet thick were placed at regular intervals along the passageway they had come from, sealing off the passageway.
If these stone doors were purely made of stone, they would not be able to stop cultivators from leaving. The key was that there were countless runes on them, making it very difficult for cultivators to destroy them.
"Boom … Boom … Boom boom boom …"
The giant beast in the tunnel walked faster and faster.
Finally, the massive beast appeared before the cultivators.
If Yang Tian were here, he would think that it was an exotic beast that looked like a rhinoceros. Its body was covered in silver-white scales, and there were three sharp horns on its ugly head.
This exotic beast's body was almost touching the sides of the tunnel as it moved forward. In other words, its body was ten meters wide.
Its four thick legs caused the ground to rumble with every step it took, giving off an incomparably heavy feeling.
It was indeed so. It was too heavy. The size of the mutant rhinoceros on Earth was far from comparable to it.
In fact, it was not just the size that mattered. The most important thing was the quality of the cells that made up the body.
As it moved forward, the eyes of this' rhinoceros' were still a little dazed.
With a glance, one could tell that it had just woken up.
As it walked, when it saw a large number of 'mutants' outside, a ferocious and bloodthirsty look appeared in the eyes of this' rhinoceros'.
Therefore, it increased its speed and quickly rushed out of the tunnel.
At this time, the cultivators also saw this giant beast clearly. When they saw the runes on the body of this giant beast, their eyes widened in shock.
The size of the exotic beast wasn't scary, nor was its weight. What was scary was that these beasts had been 'modified' by cultivators.
The cultivators who modified these exotic beasts naturally understood the fighting style of humans, as well as the weaknesses of these exotic beasts. They used all kinds of methods to make the weaknesses of these exotic beasts no longer be their weaknesses.
Exotic beasts were powerful to begin with, especially when it came to their bodies. They were much stronger than humans. If they were modified, their attacking power could only be described with the word 'terrifying'.
Runes were engraved all over the horns of the rhinoceros beast, and even on each of its scales.
After rushing out of the tunnel, this huge rhinoceros only paused for a moment. Then, it rushed towards the place with the most people.
Its speed didn't seem to be very fast. When they saw the exotic beast charging towards them, they all dodged to the side.
If this exotic beast only had this kind of speed, it would be impossible for it to bump into a cultivator even if it ran for several days and nights in this underground space.
While it was charging, the runes on its body suddenly lit up.
Immediately after, the speed of this exotic beast increased by tens of times!
An unlucky cultivator couldn't react in time. Suddenly, a white shadow flashed before his eyes. Then, he felt a sharp pain in his chest.
The longest horn of the rhinoceros had already pierced through the black armor on Kieran's body, tearing his body apart.
This horn was thicker than a person's waist. Getting hit by it was the same as getting dismembered.
After stabbing that cultivator to death, this exotic beast shook its head and rushed towards the next person.
After this exotic beast killed two cultivators in a row, the others came to their senses and started to climb up the stone walls.
Some cultivators even used the power of the air to directly fly into the air.
They thought that if they could get hit on the ground, then this exotic beast shouldn't be able to hit them in the air, right?!
After feeling that they were safe for the time being, the cultivators all made their moves and started to attack this exotic beast.
"Puff, puff, puff …"
The weapons and energy of the cultivators all bounced off after landing on this exotic beast's body. They weren't able to cause any damage to its body.
Moreover, this big fellow's speed was very fast. When the runes on its body started to activate, its body seemed to have become lighter. When it ran, there were no longer any rumbling sounds.
Most of the attacks were unable to land on its body.
