After dealing with the crab boss faster than expected, Yunan decided to move to the 33rd floor simply because there was very little gain from the 32nd floor anymore, maybe some spare change in return for hunting crab but what Yunan needed was a higher challenge, and so the 33rd floor might have what he was looking for.
Before Yunan could descend to the 33rd floor he was tasked by debauchery to do a mercenary job they thought he was best suited for, there was a client, seemingly an alchemist or a pharmacist that required intact corpsed from both sharks and orcas, he was offering a hefty sum per corpse, his only requirement is that there were no death wounds on the body and there were no damages to the organs of the monsters.
Yunan thought about it for a while and came up with a surprisingly childish idea, he could put the paralytic toxin in a ball of mana that gets absorbed by the body once it enters the digestive tract, allowing the toxin to spread unhindered to the body without the need for a puncture wound, and also allowed Yunan to control the amount of toxin to be the minimum effective dose instead of just sending many ice spears or having to manually stab the target.
Yunan spent the next week accumulating 100 specimen of each size starting from the smallest at 10 meters long to the largest at 200 meters long. Yunan thought that should be enough to get whatever results were needed, if not he could always catch a few hundred more to fulfil the needs of the clients. Unfortunately, Yunan had forgotten something, no matter how advanced a laboratory was or how skilled the alchemist they did not have the infirmary made by Hephaestus where almost anything is possible with only mana required, thus the ability to handle crates worth of anything was out of the question.
When Yunan went to the guild to submit the quest he was told to meet up directly with the client, so he just went to the man's house and identified himself as a mercenary who has come for the reward posted in the guild. Yunan was led by an ageing butler who eyed Yunan with extreme suspicion, he looked too young to be a merc of any capacity.
They arrived at a spacious laboratory by some standards, it was filled with all kinds of items that Yunan did not recognise or look at too much he just cleared his throat and said to the man behind the desk "I have with me some intact corpses, both sharks and orcas, all without damage, and I would like it if you confirm the condition of the corpses and pay me if the work is done to your liking". The man behind the desk nodded and stood up, "alright just take out the biggest corpses you have and let's check on them".
Yunan looked around and found that even though there was lots of space in the lab it would never accommodate the 200 meter long monsters so he scratched his head in embarrassment "there is not enough space here for the biggest ones I have, maybe we should start with the smaller ones, like maybe the 10 meter long ones or the 20 meters long, I would recommend you to get a bigger space to work with if you want to work on the biggest ones".
The man behind the desk thought the biggest ones that could be found are the 20 meter long ones but he now heard that they were considered small by this absurd Young man, so he decided to humour Yunan on a whim, not every day can a man like himself be subject to cheating or deception. "Alright let's go to my warehouse, it should be big enough to accommodate all your merchandise" however he was cut off by Yunan "if you don't have anything that is at least 1 cubic kilometre in volume let's not bother with all my merchandise, it seems I over hunted".
Yunan put one of each size from the 10 meters long to the 200 meters long inside his biggest storage ring and flicked it to the man " I have 100 of each size, perfectly preserved and all intact, the cause of death, heart failure or brain death. If you think you have a place where to store them then let's do that, otherwise lets only fill your warehouse". As the alchemist looked inside the ring he had to make sure he was not dreaming, 20 pairs of corpses each pair was a shark and orca of the same size, he looked again and again not being able to believe those huge corpses that were as big as hills laying there for him to watch.
"How much? You said you have 100 of each? How did you kill them, where did you find them, is this even possible, not even monsters should be able to grow this big" the man droned on and on asking endless questions from Yunan without allowing him to answer, Yunan waited until the man calmed down "they grow in size the further away you get from shore and they stop at 200 meters as for how I killed them, that, I cannot answer"
The man looked around himself for a moment before half dragging Yunan back to the guild for an appraiser because he thought that this must be a most elaborate scam and that the corpses inside the ring were faked. Inside the guild, the man used his privilege as an alchemist to bring out the highest level appraiser in the guild, a level 85 old monster. And did not forget to accuse Yunan with forgery and deceit, and trying to cheat his way into accomplishing a quest.
Yunan simply followed by and said nothing, he would pay the man back hard for this and he would certainly make him suffer, he just needed to wait for the acclaimed appraiser to clear his name and then it was time to make the man despair.
