After regaining control over his emotions, Yunan stored the shark and swam forward to try a new idea that popped into his head, if it worked he would not need to use his crossbow anymore.
Integration was an ability Yunan has forgotten about, what if he made the tip of the ice spear into toxic capsules that would shatter inside the body of the target with the rest of the ice spear, cause both poison and frost damage, if he added lighting and wind attributes, he would cause both nerve damage and guarantee a successful piercing and delivery of the poison.
With that Yunan started moving further away from the shoreline at the depth of 1500 meters, here he could train diligently and still survive with his spells if push came to shove. Yunan did not slow down as he encountered more and more sharks, their size and numbers did not matter much since Yunan could aim using echolocation and him using weapons in this place was not as much of a danger since he could trim the numbers to keep from being overwhelmed.
As Yunan kept swimming forward he reached the end of floor, he found a wall blocking the way and as he swam up he found himself in another reef that was deeper than the one near the entrance, and had a higher variety of wildlife, Yunan made Drogon swim along the reef with the aid of the genie to scan and collect anything noteworthy, to Yunan's surprise the reef was a wall that surrounded a big pool the with a radius of 100 kilometers, the pool was half a circle that connected to the walls of the floor, inside that pool was only one thing, a shark of titanic proportions.
The boss of the floor Yunan thought to himself the shark was titanic it was 500 meters in length and 50 meters wide at the jaw, Yunan stood still as he watched the sonar image of the shark swim gently around its cage while the colossal sharks of up to 100 meters long just floated into its maw, the big ones were split into pieces by the massive triangular saw teeth as the jaws clamped shut on the prey, turning the water near it into a cloud of blood and gore denoting the leftover pieces of a once great shark.
Since Yunan was still over the reef it could not swim to him but it could flap its tail at him creating a tsunami that would crush Yunan if he was not clad in his armor, Yunan doubted there were records about this place, because a boss of this scale would be too enticing for the guild and any other organizations, this thing could feed a city for months and it was basically a fish in a barrel, it was just waiting to be killed, and Yunan would never let this chance go without trying something.
First Yunan got closer to it, and not until he was far away from the reef did he understand his mistake because after a fraction of a second, the bloody maw that looked like a portal to hell greeted Yunan from the depth and swallow him whole, it was too fast for Yunan to teleport, however that made things easier for him. He used his claws to hook himself to the throat of the monster before he could be swallowed into the digestive system, he then made his toxin flow through the claws to the flesh it latched into, Yunan could feel the pulse slow down bit by bit, his poison was not as effective because the size of this thing was beyond what one would think can exist in a dungeon.
Yunan used his spikes to crawl along the mouth of the shark sending a dose of poison with each handhold or foothold he sank his claws into, it took around 3 hours for Yunan to reach the teeth and another 3 before the shark succumbed to the poison and finally died, with the death of the boss, the smaller sharks dispersed and the place turned gastly quiet, if not for some luminescent things along the walls of the cage Yunan would have ran away from terror.
Diving down to the bottom of the cage, Yunan found many treasure chests scattered around the floor, each treasure chest was sitting on top of a giant clam that had pearls overflowing from it and the floor beneath was covered a foot deep in pearls. According to the Black Fate, treasure chests spawn regularly with every new boss, if the boss remains undefeated it would spawn more and more chests, it happens that this boss would spawn a chest on top of a pearl making clam as an added reward since the clam can be claimed and raised, and this cage here had all the types of clams that could be found in all the water floors, this boss cage became a treasure trove since it has never been cleared before.
Yunan cast enough mage light spells to light up the whole area, although it was not enough to shed light on the whole cage, however the portion under the light was beyond a doubt what Dustan had wet dreams about, Yunan sent a live video to Debauchery asking them "how busy are you?" As he showed the the place he had shed light and "this is just 1% or less, the pearls you can see are at least 1 foot from the ground" Yunan could see Debauchery change their faces from confusion to doubt and finally there was a unanimous "i want to see it before you pocket it, as it is now, i promise not to touch"
Yunan chuckled to himself and told thr genie to bring them here, but if anyone dares to touch send them back. As expected Dustan and Bai broke the promise immediately but were sent away the moment they lunged forward, Balin asked for permission to inspect some fist sized pearls while Leader and Fae pulled a Scrooge McDuck and dove into the pearls, as for Lucian he was to take pictures of the two girls as they satisfied their vanity.
Yunan now had the right to take away all the clams and chests in the cage but one of each so he began the task of using his automated looting at the maximum range of 5 kilometers and made lap after lap along the most optimal path indicated by the genie leaving behind Debauchery in the lighted area for last, he then brought the rest of the family to take a look and enjoy without stealing anything.
