Seeing the unnerving sight of human skeletons piled on top of each other before him and the skulls looking straight at him, paired with his conclusion, Sebastian could not help but shudder a bit.

  As an anatomist, he was not scared of blood, gore, and anything related, but things related to death, catacombs, and mausoleums were scary to him.

  This was even more obvious when he was experiencing it from a first-person perspective. This was unlike horror movies where he watched behind a screen, this was the real deal.

  He could not help but lampoon that this world was rapidly becoming more fantasy-like in a dark manner that he did not like, which scared him.

  The only thing that prevented him from running with his tail behind his fins immediately was the fact that he was not a human weakling anymore, he was now a young Megalodon with magic and battle skills.

  At this moment, he really wished that he could make use of his ultra-range electroreceptors skill immediately. With that, he could penetrate obstacles and see much further.

  Despite this unfortunate shortcoming, he still made use of what he had.

  [You have activated skill: Advanced Electroreceptors.]

  [You have manually manipulated your electroreceptor skill.]

  Doing this, Sebastian was able to narrow down the point of focus of the skill towards the direction where he detected the 2 Giant Worms.

  Observing through that specific tunnel, he didn't see any other predator except the Giant Worms. Giving himself some psychological confidence with that, he finally moved forward slowly.

  As he slowly moved through the tunnel, his keen observation enabled him to notice much more human touches in this strange catacomb.

  Through the help of his camouflage organ, he was able to get extremely close without alerting the 2 Giant Worms, enabling him to observe the pile of skeletons more closely.

  As he observed the human skulls, he suddenly saw a green light flash through one of them, spooking the hell out of him.

  Whoosh!

  One skeleton suddenly stood up from the pile of bones, revealing itself to become what seemed like a skeleton snake with 4 legs.

  Due to the movement of the skeleton, the Giant Worms were alarmed. While discovering the skeleton, they also discovered the predator that was now dangerously close to them.

  Even though he was spooked by the skeleton snake, Sebastian was able to react on time, attacking first before he was attacked.

  [You have activated skill: Shredding Bite.]

  [You have triggered Adaptation: Spikes!]

  [You have activated skill: Spike Attack.]

  [You have activated skill: Empowered Tail Fin.]

  Crunch!

  Sebastian's deadly sharp row of teeth immediately came down at the nearest Giant Worm, pulling and shredding a sizeable amount of flesh in the process.

  As soon as his row of teeth bit into its flesh, he turned his body, stabbing his spikes into its side in the process while using his already stiffened tail fin to slash at the other Giant Worm who was in the process of attacking.

  In a moment, he dealt 3 attacks. Almost at the same time, he activated another skill as the skeleton snake rapidly swam to his face.

  [You have activated skill: Magic Shield.]

  [You have activated skill: Magic Teeth.]

  Bam!

  The skeleton snake rapidly collided with the magic shield, the impact spreading cracks through its bony body as it shriveled like a smoked Shrimp while being repelled backward.

  It tried to retaliate but Sebastian already chained another attack against it. He removed his row of teeth from the first Giant Worm and opened his mouth.

  Pu! Pu!

  His magic empowered teeth shot out in clear already defined trajectories, rapidly impaling the skeleton snake and in moments, it was shattered into fragments of bones.

  Ignoring the system notification, Sebastian rapidly turned to face the 2 Giant Worms as they were already in the process of using their strange Silk magic.

  Hitting and crushing one with brute strength with his Battering Ram skill, he killed the other by firing a Sonic drill through its brain.

  After doing this, he started observing his surroundings for any other danger while making sure not to focus on the pile of bones again.

  He wasn't sure if the skeleton snake was a result of him focusing on the pile of bones, but prevention was better than cure. This encounter already made him lose interest in this catacomb, but a strange curiosity made him stay.

  After waiting for about a minute and not detecting any danger, he finally heaved a sigh of relief while going through the system's notification.

  [You have killed a Mutated Poison Worm- Level 11: You have gained Experience.]

  [You have gained 3 Skill points and 5 Adaptation points.]

  [You have killed a Mutated Poison Worm- Level 12: You have gained Experience.]

  [You have gained…]

  [You have killed a Tainted Skeleton Snake- Level 8: You have gained Experience.]

  [You have gained 2 Skill points and 2 Adaptation points.]

  [You have obtained a special system clue: Experimental Ground.]

  [This Seamount was once an experimental ground of the Atlantian Mage Professors. The Experiment failed, and an abomination was created here, forming a terribly dangerous substance.]

  [Experiment Name: ???]

  Seeing this, Sebastian was once again stunned. This was his first real clue to other humans since coming to this world, he could not help but feel his taking in liquidated oxygen become rapid.

  From this, he also got another discovery, Atlantis humans could become Mages, which meant that the sea creatures were not the only ones with magic.

  Going to the experiment train of thought, he could not help but associate the experiment with the Necromancy King.

  Not only was he inside a catacomb related to death where he encountered a strange skeleton snake, the 2 Death Dragons that he saw may imply that a nest of those abominations was close by.

  And all these paired with the experiment pointed to Necromancy.

  He badly wanted to explore deeper to know the truth, but the terribly dangerous emphasis from the system was rare, which gave him trepidations.

  In the end, he decided that before leaving, he should just explore the periphery of the catacombs, if possible just this tunnel to its end to understand the overall situation a bit.

  He just had a breakthrough, pairing this with his trump cards, he did not believe that he could die so easily.

  Despite this, he repeatedly cautioned himself in his university lecturer's tone. "Sebastian, only the periphery. You are too young to court death".

  He knew that if he used his voice, his subconscious may decide to ignore it, but definitely not the Mathematics Professor's voice.

  "Mathematics Professors were King".
