Isn't this a bad thing? The mermaids, they are all hoping for a positive outcome coming out after this visit of ours, instead, now we have to kill their king because we failed to save him from becoming a devil

The old frail mermaid king was no more. He still smell a bit of an old man, but his appearance now is that of a young looking person, though that's not all. He now possess two crab like pincers coming from his back, with the his mermaid tail becoming more like a elongated snake body, where in it, thick armor line up parallel to each other, boosting its defense

The important looking person, having seen all of it, run away as quickly as he can, and I heard his screaming, telling the castle worker to neglect their job and escape, while asking those who can fight to provide support from afar. That might be a great idea

As the mermaid king whip his armor tail like it was nothing, Mahsuri, almost resembling Mrs Khamishah, block it with her bare hand, while Kara, seeing this opportunity, use it to electrocute the mermaid king. It works as foam started to coming out of the king mouth accompanied by epileptic movement, but the pincer coming out of the king remain unaffected, like having a second independent nervous system, it started to attack Kara, which gracefully dodges the incoming attack before sending out wind gale magic into its direction. While part of it does pierce the skin of the mermaid king, causing him to bleed, the one sent to target the pincer cause no harm whatsoever

In response to Kara's attack, the bleeding part of the mermaid king heal itself, before a shell like a turtle appears. Strange, this must be his ability after gaining the power of a devil. He's able to borrow the properties of aquatic lives and uses it to his advantages. I'm sure by the end of this fight, he will be unrecognisable

Mahsuri start to unleash her wrath, swinging her sword, she peel off the shell like armor from the tail of the mermaid king, which kept flailing left and right, destroying the castle wall.

"Freeze!" [Charlotte]

In order to ensure he's not causing any more damage, and to keep in him check, I simply freeze him, encasing him in an iceberg like structure, but somehow, his body begin to change. There are corals like structure coming out from his skin, with an orange structure taller than the surrounding corals, coming out and start heating up his body, causing the ice to melts. That structure then unleash an underwater lava magic, which Elise gladly take control of to peel the coral from the mermaid king

The mermaid king extended both of his arms, and a harpoon with an anchor comes flying from both sides of the room. He uses the harpoon to stab Mahsuri, but Mahsuri fortunately saw it coming and block it with ease, and as for the anchor, that heavy anchor get swing like it was nothing before getting thrown at my direction.

"Adamantoise!" [Mahsuri]

Her golem shielded me. The sound of adamantoise shell and the anchor colliding produce a deafening bang, and I'm glad adamantoise shield me, if not, I will sustain heavy damage, or worse

The mermaid king start to went outside, and there the first thing it do is to take control of the Leviathan. The Leviathan tries it best to resist, it really does, but against the influence of the mermaid king, there isn't much for him to do but to abide the commands. Luckily, the blackish miasma that covers the Leviathan body didn't transform him any further, so I guess he still keep on resisting it

"Krakeny, Ice missiles shark! Go!" [Charlotte]

"Pseudo Leviathan" [Mahsuri]

Before the Leviathan starts to rampage and possibly destroy the kingdom, I decided to face him first. Without Mahsuri Pseudo Leviathan golem, I don't think I will stand a chance facing against this creature, but now, I'll try my hardest to beat it

The two monsters wrap around each other, with each one of them trying to constrict the other into submission. That sight alone is enough to send panic across the kingdom as I can hear mermaids left and right screaming. Other soldiers also comes to my aid, trying their best to beat Leviathan

"Freeze dry" [Charlotte]

Covering the Leviathan with freeze dry magic while carefully sparing the golem, the magic cause the Leviathan to get hurt and let out a roar, but it simply ignore it since a bigger threat than I am is still constricting it. That's good as I can keep sending this attack without getting

"Water cannon blast!" [Leviathan]

"!" [Charlotte]

A simple spell coming out from the Leviathan, but coming from him, it actually hurts a lot as I get blown away easily. If it wasn't for Krakeny for dampening the blow, and the ice armor I made, I will seriously get some bony fractures, though the soldiers, some were even unlucky

The Leviathan start to bite his brother now turn golem, and part of the golem started to disappear. This is bad... This is really bad. I need to support the golem ASAP, but how...

(That giant blue orb... She said it was a magic core isn't it...) [Charlotte]

Judging by her story, I get the feeling that I could utilize it, and so, I quickly swim toward the giant blue orb, touching it and

(So much mana!!!) [Charlotte]

This will be difficult to control, but rather than controlling it, what I should do is

"TSUNAMI! TSUNAMI! TSUNAMI!" [Charlotte]

Since the mermaid soldiers are there no more, I sent out giant waves one after another toward the Leviathan direction. At first, it simply resist my attack, trying it best to come towards my direction, but I simply increase the power output and create a bigger underwater tsunami which causes it to get swept along by the current.

"Now! Warships. Ram into the monster" [Charlotte]

Summoning legion of warships, it uses the water current to its advantages, ramming the Leviathan one after another. Since the influence of the mermaid king started to get weaker and weaker, I can see consciousness starting to appear from the Leviathan's eyes, and without missing a beat, I propel myself with water magic, and try to remove any blackish miasma from it all by myself

~Chomp~

I dodge, almost getting eaten alive by it, but that's not all, of course the blackish miasma don't want to let go of it precious specimen, so it still try to control the Leviathan. The Leviathan, still under control, blast a whirlpool magic, dragging me inside of it before getting slammed hard against it flesh, before getting attack by the blackish miasma directly.

"IT HURTS!" [Charlotte]

Feeling enrage, I simply activate my blessing to it full capacity, trying my best to destroy the blackish miasma. It's hard, and so

"Ice missiles shark! Just chomp his skull away!" [Charlotte]

I order my shark golems to eat part of the Leviathan. He try his best to ward off the sharks, but between the enrage me, the sharks, the Pseudo Leviathan and the warships ramming it non stop, Leviathan has a hard time countering it, and once the flesh is expose

"Here! Help yourself and stop your rampage!" [Charlotte]

I cleanse the Leviathan from the blackish miasma through the flesh. Sending all of my mana inside of his flesh, and just before my mana run out

"Princess! Please stop! I'm fine! I'm fine!" [Leviathan]

"Really...?" [Charlotte]

"Yes! Yes! Believe in me!" [Leviathan]

I guess I have to. I don't have any energy left to fight. If the fight was to dragged any longer, or the blackish miasma influenced on Leviathan i stronger than I thought, than I wouldn't have the chance to save him

"Leviathan, please... let me rest a bit" [Charlotte]

I'm dizzy. Me out of all people are now experiencing mana depletion symptoms. I just wanted to vomit right now, but I don't even have the energy to do that.
