As soon as Sebastian came out of the construction department expanse, he silently swam leisurely as the conversation with the shark elder came back to him.

  Though he declared confidently that he would show the elder that anatomy could benefit the clan, he wasn't exactly sure how he could prove that when nobody even believed him.

  It was frustrating, but he had no choice but to take the stabler choice.

  After thinking, he decided that growing his hunting team further and engaging in more hunts with them was the most stable choice right now.

  That way, while accumulating shark points, he could also prove to the sharks that he had no ill intention with joining the clan. It may prove difficult but he believed that he was up to the task.

  But before all that, he needed to address the problem of his evolution.

  Like the elder told him, if he became a purple tier shark was when he would have more talking power in the clan.

  Then, the idea of him creating a department in the clan would no longer seem as alien and would be better received by both the normal sharks and the elders alike.

  Still, this was the problem, because he felt afraid of going ahead with his evolution without receiving guidance first. The example of the now Goblin Shark, Teeth was still firmly ingrained in his mind.

  As he thought of this problem, he soon discovered that it was not much of a problem Afterall since he now had shark points.

  When the rules were explained to him, he was told that shark points could enable him to register into any of the domain departments of the clan. And with enough shark points, he could also seek the guidance of any of the elders.

  Of course, as he shared the same magic domain ability with Elder Dangle, he was more inclined to go seek her for help.

  As soon as this thought settled in his mind, it could not be stopped as he turned to swim towards another part of the working segment of the cave where the sound domain department was located.

  It did not take him long before he arrived at his destination.

  As Sebastian swam closer, he saw 2 sharks standing guard at the entrance inside the department expanse. There, he was stopped. He revealed his motive before he was allowed entry.

  For some strange reason, even though this department was not like the other main working departments, it was still filled up with sharks.

  Apparently, the sharks already mostly recovered from the blow dealt by the news of what happened to the Gigantic White hunting team as they chattered on, engaging in different conversations with themselves.

  In the end, though they were intelligent, they were sharks, not humans. Even humans forgot things easily, not to talk of sharks.

  Through their conversations, though some were mostly random, Sebastian was still able to sieve through them to deduce that a lecture by Elder Dangle was scheduled to commence in 30 minutes.

  For some reason, he felt relieved on hearing this as he was once again already worrying about how he could secure a meeting with the elder.

  "50 Shark points to register into the sound domain department".

  "This is but a discount, after the lecture from the elder today, the price would be brought back to 100 Shark points so take advantage of it".

  Hearing this, Sebastian's face became weird. If he had lips, they would have already started twitching furiously as he felt vibes from his previous world here.

  "Are shrewd marketers in every world that I go to?"

  He ignored this and swam closer. "I want to register".

  "Welcome, young shark. You just made the best decision of your life".

  Through a machine, the enthusiastic fat Great White Shark immediately went through with the procedures and confirmed Sebastian's shark points. Through the machine, 50 shark points were extracted for the registration.

  "Congratulations lad! You are now part of this department".

  Sebastian smiled back at the fat shark as his system confirmed it to him. For some reason, he felt fat merchant vibes from this shark which only made the current situation all the more weirder.

  "Do you want to attend the elder's lectures? You need just 15 Shark points".

  "Yes, extract the points".

  Sebastian already knew of this beforehand, so though he felt like he was being scammed due to the shrewd smile from the fat shark, he smiled back as he knew that this was the normal procedure.

  After he paid, the fat shark used what seemed like a magic stamp to put an imprint on his body which was his ticket to the lecture.

  After that, Sebastian waited with the other sharks.

  "The Elder is here!" "The Elder is here!"

  Exactly 30 minutes later, Elder Dangle arrived at the department expanse. With her entering, the 2nd gate to the lecture chamber was finally opened to allow the sharks with tickets in.

  …
A few minutes later, after everything settled down, with all the sharks scheduled to receive the lecture in the chamber and the elder hovering above, Sebastian finally had a close-up view of this shark elder.

  Apart from her enormous size, another defining factor of the elder was that her upper body was a light blue color. 

  If not told beforehand, Sebastian would have found it hard to know since the elder had no defining factors pointing out that she was a female shark.

  In conclusion, Sebastian felt a sense of oppressive suppression from her. This was a formidable predator that already experienced the tribulations of numerous battles and a survivor of near-death experiences.

  The elder did not waste time as she started her lectures soon after.

  "…Sound is everywhere, sound is omnipresent!" 

  "…To be the ideal sound domain magician, you need to be imaginative and swift in harnessing the sound around us…" 

  "…When we breathe, we make sounds. When we eat, we make sounds. When we kill, we make sounds. Practically doing anything induces sound, which means that we sound domain magicians can never truly be restrained…"

  "…To be the ideal sound domain magician, you need to be proficient in sensing vibrations. They are the key to fulfilling your potentials with sound magic…"

  "…Here with you in this lecture, I can feel dozens of beating hearts. I don't need to attack you physically; I can kill you all by just tempering with the sound beats of your heart…"

  "…This is the power of Sound!"

  "…All you need is an imaginative spirit and you can excel as a sound domain magician. Think beyond the boundaries of your brain, try to be a trailblazer all the time as this is the way to excel with sound magic…" 

  "…When swimming, think of how you can make your peers quake in their tail fins without them knowing that it was caused by you. When in battle, think of how to attack your opponent without them even knowing they are being attacked…"

  "…Be daring! When your elders speak, think of how to sound-slap them without them knowing that you did it…"

  "…In your everyday life, let your thoughts be 'how can I turn the growling of my enemy into the most lethal attack ever?"

  "…Always remember this, sound is everywhere, all you need to do is to be imaginative and harness it. Only the swift sound harnessers are the real sound domain magicians…"

  "This is the end of today's lecture. Next time, we'll be going deeper on the techniques to identify and swiftly harness sound around us".

  With that, the shark elder finally flapped her tail fin to swim away after a long lecture that left every of the listening sharks in a trance.

  "Thank you elder!"

  "Thank you elder!"

  The sharks hastily recovered and expressed their gratitude. Apparently, they learned a lot from this lecture including Sebastian.

  Though Sebastian badly wanted to find a quiet environment to devour and properly understand the knowledge that he just got, he swam out of his position as meeting the shark elder was still his priority.

  "Shark sensei, please wait".
