Cautiously, Sebastian's tail flapped left and right as his enormous body moved through the catacombs while he observed keenly with both his eyes and his electroreceptor skill.

  On one side of the tunnel were the normal walls, while the other side had its walls formed from the pile of human skeletons.

  The more he observed the tunnel, the more it seemed like a hall to him. After more careful observations, he deduced that the main body of the hall was the part already covered by the pile of human skeletons.

  Due to how the skeletons were piled and arranged, he could not deduce exactly how they died.

  "Did a huge war erupt here or something?"

  As he thought to himself, his eyes became sharp as his electroreceptors just warned him of another group of Giant Worms ahead.

  This time, they were 3 of them, slithering on top of each other like they were doing inexplicable things. They were so focused on their little fun playing that they didn't notice the incoming danger.

  Already experienced with dealing with them, Sebastian did not rush as he found a better angle to better observe the 3 siblings.

  Though he just had a feast before entering this underground catacomb, he knew that his dimensional storage stomach would not complain of more food.

  He already knew the squelching sound that they made to communicate with themselves, and his strategy this time was to take advantage of it.

  Even if the one made by him wouldn't make sense, he believed that the 3 Giant Worms would at least react to it.

  [You have activated skill: Sound Control.]

  This was Sebastian's first time using this skill but for some reason, he felt like he was already a veteran in controlling it. He knew that this was a specialty of his system, so he was calm.

  He controlled the vibrations in the water, tapping into the residual sound waves that were left in the water to form a sound of his own.

  Squesh! Squash!

  Suddenly, a sound that was extremely unpleasant to the ears reverberated. He even flinched slightly when he heard the sound.

  The 3 Giant Worms stopped their activities at the same time, then they all turned to face the direction of the sound.

  They didn't have eyes, only an adaptation that was like antennas on their foreheads waved in the water like they were trying to pinpoint where exactly the sound came from.

  Squish! Squosh!

  This time, they finally moved to go check out the fool who was disturbing them who could not even form a coherent communication sound.

  With the help of his camouflage organ, Sebastian's enormous body slightly blended with the walls of the catacomb tunnel, preventing neither of the 3 Worms to detect the anomaly.

  At this moment, the first Worm was already directly below him, granting him the perfect opportunity to strike and he took it.

  [You have activated skill: Battering Ram.]

  [You have activated skill: Shredding Bite.]

  [You have activated skill: Sonic Drill.]

  Boom!

  His enormous body quickly moved with the skill, crushing the body of the first Giant Worm to the wall. In this process, he quickly disengaged and opened his mouth, biting at the second Giant Worm.

  While doing this, the familiar sound waves in the air quickly converged together, forming the dangerous sonic drill before firing at the last Giant Worm.

  Crunch!

  While he repeatedly bit at the Giant Worm in the middle, the damage that he dealt to the other 2 made them want to instinctively roar in pain but he reacted before they did.

  [You have activated skill: Sonic Reflection.]

  As soon as both Giant Worms opened their mouth, the sound did not get to come out as it was stuck in their throat before hitting back at them.

  While doing this, he finished the Giant Worm in the middle with one final bite before going back to the one at the front.

  Just 2 consecutive bites and the fellow also succumbed. Then, he finally turned to deliver the last blow to the fellow who was still suffering from the sonic drill damage to its brain.

  [You have killed 3 Poison Worms- {Level 14,12 & 11}: You have gained Experience.]

  [You have gained 8 Skill points and 15 Adaptation points.]

  Not seeing it as much of an achievement anymore despite the speed at which he killed them, he quickly gobbled down the meat of the 3 Giant Worms before continuing his exploration.

  In that same tunnel, as he explored, he met other groups of Giant Worms which he easily killed after chaining a few skills against them.

  Of course, the main thing that allowed him to continue his exploration while killing was the fact that he didn't make much of a commotion during all the killing.

  At this point, he more or less confirmed already that the skeleton snake appearing was a result of him staring directly at the pile of skeletons.

  This brought him another question that he had no answer to, what was special about the skeletons? Is it something that he could dissect to know the answer?

  Putting that behind him for now, he continued observing carefully. Another fact was that farming Skills and Adaptation points so easily left him in a good mood, which prompted him to continue exploring.

  A few minutes later, amidst the gloominess of the catacombs, he finally saw something different.

  At the very end of the tunnel where it branched into other tunnels sat a blueish white box. The box pulsed in a lifelike manner, while the white slowly dissipated from it, spreading coldness to the surrounding.

  Seeing this, Sebastian did not become rash and go directly, he instead decided to observe from afar with his electroreceptor skill first.

  Manually controlling his electroreceptors, he focused it on the box. Immediately as he narrowed its range down, he felt a painful prick in his brain.

  [You have been tainted by the Poison box: You have attracted the attention of the Wandering Hound!]

  "Tainted? Wait, I attracted attention?"

  Tap! Tap!

  Suddenly, he heard a sound that he was extremely familiar with from one of the tunnels connected to the one he currently was, the sound of a lady walking with high heels.

  This was an extremely normal sound in ordinary circumstances, but this was clearly not an ordinary circumstance. This was Oceania not Earth, and besides, he was inside a strange mausoleum.

  He wanted to turn and escape immediately but he held his nerves and decided to wait. He wanted to see the source of the sound first, he didn't want to escape without even knowing what exactly was happening.

  As the tension grew in him, the source of the sound finally appeared.

  Tap! Tap!

  Sebastian subconsciously looked down, his eyes focusing on the beautiful pair of high heels and the fair legs on them. He was about to heave a sigh of relief but when he traced this up, he stiffened.

  The delicate female legs went up to a point before being replaced by black fur, the remaining part of these beautiful legs was a bloodthirsty hound.

  The enormous hound had 3 heads, the ones on the left and right were normal dog heads, while the one in the middle was that of a beautiful girl.

  The human head suddenly turned to look at Sebastian and asked in an extremely feminine tone that should induce pity, but could not to the current Sebastian.

  "Why did you disturb my sleep?"

  "Me?" Sebastian felt a chill down his spine.
