"Let him in".

As soon as this voice reverberated, the shark guard hovered in the water while making its body straighter as it obediently opened a path to let Sebastian through, leaving him dumbfounded.

"How did the elder know I was coming?" Sebastian asked this in his mind but it did not slow him down as he was already on his way inside.

Going through the entrance, he immediately noticed the difference between this chamber and other chambers in the cave.

Apart from the more perfect caving craftmanship on par with that in the throne chamber, inside was a long spiraling passageway that led downward. The water in this passageway flowed faster, just like water rapids.

Seeing this gave Sebastian weird vibes but it could not stop him as he continued inside the passageway.

Whoosh!

As soon as his head entered, he was shockingly pulled downwards by the water force despite his weight. His body spun, following the patterns of the spirals in the passageway as he soon disappeared from sight.

[You have activated skill: Advanced Electroreceptors.]

With his electroreceptors active, Sebastian finally escaped the feeling like he was stuck in a washing machine. He tracked his movements from here in the spiraling passageway until he entered normal flowing water again.

Immediately after his body stopped, Sebastian's eyes widened as through his electroreceptor vision, he felt like he just entered a new world.

A world under the clan cave presented itself before Sebastian.

Dozens of sharks were in this place, and different from other sharks, they had a brown earthen armor film covering their body as they engaged in different activities, mostly working.

This was an underwater vacant space inside the cliff walls. Pillars were made at different locations of the space to hold the earth ceiling.

Some of the sharks worked on the cliff walls, using their control over earth magic to manifest various effects. Some worked together to soften the walls, while others-controlled boulders and threw them at the wall.

This action made the cliff walls have depressions and break, a chip at a time.

Before Sebastian's eyes, after consecutive breaking from the sharks' teamwork, they succeeded in extracting a glowing orange orb which another group of sharks came to take away.

The sharks didn't just break from one point. They formed various teams that broke the cliff walls from other locations.

Sebastian didn't know the use of the strange orange orb, but he felt immediately that they contained magic power.

Apart from those working on the walls, other sharks engaged in other activities in this expanse. Another which caught his attention was those that worked at a remote corner of the expanse.

This group of sharks manipulated the cliff walls, using some strange earth magic technique to extract hot flowing magma from the walls.

While they did this, other sharks collected this hot flowing magma in iron plates. Even as others did this, others controlled specialized hardened rocks, using them to hammer the flowing magma into shape before they solidified completely.

Seeing all these, Sebastian felt like he entered a medieval blacksmith workshop. He was awed. Apparently, this was the construction department chamber under Elder Marble's leadership which he couldn't see the other time.

After taking in and digesting all the eye feast before him, he finally turned to look for who he came to meet.

He didn't have to look long, the elder's much bigger size than the other sharks easily revealed his identity. This enormous shark was currently hovering before the cliff walls, he was working too.

With eyes filled with focus, the shark looked at the wall as it shook to his will with rock fragments falling like an earthquake was imminent in the walls.

While the others cooperated to do it, he broke through the cliff walls alone, showing his power as a purple tier earth domain magician.

Seeing that the shark was focused, Sebastian kept quiet, not knowing if speaking would disturb but his worries were misplaced as elder Marble spoke first.

"Nanga already told me about your proposal".historical

Hearing that, Sebastian immediately became excited but what the elder said next brought him straight from heaven back to Oceania.

"My answer is, No!"

".."

The elder continued. "I don't know what induced such fantasy in you, but creating and maintaining a department is not as easy as it seems".

"Besides, before creating a department, you have to bring evidence that it would bring tangible benefits to the clan. We don't just create departments; we create departments with a goal to benefit the clan".

"You've seen the benefits that my construction department brings, you've seen the benefit of the healing department, what benefit does your department idea brings to the clan?"

"By the way, what is the name of the department that you want to make?"

"Anatomy department!" Sebastian blurted out.

The elder's non-stop talking and reprimanding seemed to have affected him, causing him to answer immediately after being asked.

"Hmm". Elder Marble turned to face the shark. "Anatomy.., what's that?"

"It's.."

"See kid, you need to stop living the life of your dreams and start living a realistic life. I heard of you taking Shanks out to hunt, the fact that he survived and even benefited does not mean your action is justified".

"Be warned!"

"Talk about creating a department only after you have crossed into the purple tier, just like me".

"Leave my chamber, I have a meeting to catch up with".

".."

Sebastian felt it once more, from his heaven, the elder's ruthless reprimanding words grabbed and threw him back to Oceania.

He felt like laughing at himself. For years or even decades, only these departments have been in the clan, what gave him the fantasy of believing that his idea would be accepted once he proposed it?

Besides, as the elder said, he had no idea what anatomy was. Adopting a department for it without even knowing what it meant was plain stupid.

The elder's words a moment ago showed how intelligent he was, but it also showed how different his thought process was from Sebastian.

Compared to him who lived through a world where every child went to school where they learned every basic knowledge, in Oceania it was vastly different, perhaps the only exception being Atlantis and Atlantians.

This was a predator world, not a diplomatic and political world.

"How many times do you want me to repeat it? Leave my chamber!"

"Sorry elder". Sebastian apologized and turned to leave the chamber.

As he left, only one thought was on his mind.. "I'll prove to you that anatomy can benefit this clan".
