Ocean Master

On entering this familiar and gloomily dangerous region where most of the area was filled with darkness, Sebastian was left shocked. 

"The Catacombs?!"

His mind was thrown into chaos as he experienced mixed emotions.

Outside the inheritance ground when the battle to secure the entrance was still ongoing when he saw the deadly predator called the Speed Demon become the first to enter the inheritance ground, he confirmed the location of the entrance.

The Sea King Inheritance was unexpectedly planted in a region of this seamount where he originally half-explored once.

Immediately as he knew this, he was happy, thinking that he had some form of information advantage over others. But when he finally entered the inheritance ground, his advantage hopes were ruthlessly crushed.

When his system indicated that he was trapped inside a Virtual-Reality domain, optimism returned, but he tried to suppress it to avoid being disappointed.

Now, he could finally feel the joy of having a unique advantage over others.

Sebastian of course double-checked to confirm and he was not wrong. 

The huge network of underground tunnels and passages that were built in the style of humans and the piles of human skeletons that were piled on top of each other could not be easily faked. This was the catacomb.

Not only that, he appeared at the exact same place where he once did during his first time when he explored this spooky catacomb.

The only difference was that he entered through a different tunnel entrance that the Sea King\'s will already modified into the entrance of the inheritance.

Like before, from his position of this underground water hall that he was, 5 tunnels extended into different directions.

Sebastian didn\'t pay attention to these though; his attention was more on the memories that he gained from his previous visit here which were the unique advantage that he now had over the others.

At this moment, he had already become serious again. He knew that as the last round of the first test of this inheritance, it would probably be the hardest also.

His brain went into overdrive as he started rapidly recalling.

If he remembered correctly, his system gave him a system clue that this seamount as a whole was once a large experimental ground of crazy Atlantian Mage Professors during his last visit.

This place was the heart of the experiment ground, and due to the experiment failing, an abomination was created here, forming a terribly dangerous and extremely desirable substance.

Apart from this, Sebastian remembered other matters. These were not told to him by his system, he experienced them himself.

During his last visit, the things that gave him the most impression of this place were the skeletons that filled everywhere which one of them later turned to a skeleton snake, the Poison Worms, and of course the Abomination Hounds!

The Abomination Hounds were an encounter that Sebastian would probably rate among the most bizarre of encounters since reincarnating into this world.

The strange monster that was formed from a mixture between a delicate Atlantian lady and a mutated Hound was so bizarre that he had nothing to describe it with. He simply referred to it as an anomaly.

Another horrifying fact was that the strength of this monster was the real deal. Their impeccable control over earth magic, their almost instantaneous movement speed skill, and their undead magic made them terrifying opponents.

Putting this all together formed the most bizarrely powerful monster ever. Just thinking back on the encounter now left Sebastian shuddering in fear.

But, why was this the location of the endurance test?

Almost immediately after Sebastian thought of this, his eyes opened as wide as they could, forming what seemed like giant glowing lanterns as a frightening possibility emerged in his mind.

Sebastian was shocked. "Don\'t tell me…"

While he still spoke, the familiar writing appeared before him once again.

"Hahahahaha!"

"The endurance test is endless! The same way life challenges are endless!"

"You know how inside here is, the only exception to this rule is if you manage to annihilate all the dangers that are inside which you know is impossible".

"Let the race…"

While the writing was still materializing, somewhere deep and dark inside the catacomb, a faint white glowing light that seemed like a spirit manipulated something as a green tonic was dropped inside a pure white orb.

As soon as the green tonic was dropped on it, the pure white orb vibrated like it was resisting the green invasion before it became tainted the next moment.

The white orb no longer resisted, the green invasion succeeded, the orb was no longer white, it was now a gloomy green color.

It became evil, then this evil spread everywhere, through the whole catacombs, affecting the warped ecosystem that already adapted here.

The Poison Worms, the experiment skeletons, and the Abomination Hounds were all tainted. Their eyes all turned an evil green color.

The next moment, all these monsters that resided inside the catacomb went berserk. It was like, the catacomb finally woke up from a deep slumber.

"Let the race of survivors begin!"

When the writing finally finished materializing, the catacomb also finished waking up from its slumber, then its horrors were unleashed.

ROAR!!!

A deep guttural roar reverberated through the catacomb the next moment.

"Let the race of survivors begin!"

"Let the race of survivors begin!"

This sentence kept on echoing in Sebastian\'s mind, followed by the deep guttural roar, then he finally came to a realization.

The endurance test already started.

[You have activated skill: Advanced Electroreceptors!]

As soon as his electromagnetic sense blasted out, from the 5 tunnels, Sebastian detected a despairing number of terrifying monsters emerging.

Poison Worms, Skeleton Monsters, and Abomination Hounds, came out like an unstoppable tide of beasts.

Creak! Creak! Crack!

While this was still happening, Sebastian heard spooky creaking sounds. Once he turned his head, he saw yellow flickering lights from the skulls of the skeletons that were piled up in this hall.

All the skeletons were awakening!

The Catacomb Disaster was finally awoken!

"Oh boy!"
