Merfolks who are not suited for land had their mages and priests cast water, flooding the land.
With a significant amount of water, the pitfall traps and the moat became useless.
"FIRE!!!"
Leon and Persephone continued to rain down the sea serpent with arrows, which eventually took a toll on it thanks to Aldo junior who was keeping the sea serpent in one place.
"Chief, the sea serpent is heavily injured!"
"Continue! Do not back down from a few humans!!! Avenge the princess and my heir!"
The merfolks' morale did not wittle down at all after the defeat of the sea serpent.
"They are getting closer now!"
"It's showtime then!!!"
Marco inhlaed deeply as he got himself ready in front of his weapon.
"Twinkle~ Twinkle~ Little Star~ How I Wonder~ What You Are~!!!"
As Marco begun to sang in front of a voice enhancing megaphone, the merfolks stopped from the tone deaf singer singing a song that had a paralysis effect.
Boom! Boom! Boom!
Three giant arrows was fired towards the merfolks from the forest.
The trolls who were waiting for the signal, Marco's singing, then started to fire the three ballistas from the forest.
"Up Above~ The World So High~ Like A Diamond In The Sky~!!!"
Each second that passes, the merfolks number decreased.
"Heilas. Gremoa. Tarron. Vuloes"
With a spell from the Blue Coral tribe chief after he managed to free himself from the effects of Marco's voice, the merfolks gained a sort of defense, making them immune from the horrid song.
Two small units of merfolks started to head towards the forest.
"Switch to phase 2"
"Okay!"
After quickly drinking, Marco went back to singing. This time, his allies receive buffs instead.
"The Wheels On The Bus Go Round And Round~ Round And Round~ Round and Round~ The Wheels On The Bus Go Round And Round~ All~ Day~ Long~!!!"
With the singal they received, Lexi and Anise raised the wire they created.
"AAAH!"
The wires laced with Anise's poison slashed those who run through it and corroded their bodies.
Meanwhile, the two small unit that went to the forest in attempt to stop the ballistas from being fired fell for the traps that was laid beforehand.
All sorts of boobie traps from simple snares to dozens of venomous snakes flying towards your face were experienced by the merfolks.
Seeing that they have underestimated their opponents and that they have fallen to their traps, the Blue Coral tribe chief became enraged.
"Do you all swear loyalty to the sea?"
"We do, chief!"
The nearby merfolks knelt down and had their vitality sucked from them, leaving them no different from dried corpses.
A surge of mana, converted from the merfolks vitality, swirled around the chief's webbed hands.
"You humans are-"
Bang!
They all turned around and saw Tony from the top of the castle with his rifle.
"You all are going all out. I can't possibly afford to rest inside the castle now, can I?"
"You sure are one resilient bastard!"
"I'll be taking a rest now. Make sure that I won't be in heaven once I open my eyes" Tony said as he closed his eyes from exhaustion.
By interrupting the magic being casted by the Blue Coral chief, the merfolk suffered internal injury.
"My daugher and son-in-law are dead. My people are dying all thanks to my incompetence. If I had sent a small party of elite to scout first, none of this would have happened"
Mad at himself, the Blue Coral chief cursed at himself as he forcefully tried to create another magic circle.
"Aldo said that a magician whose magic has been distubed won't be able to cast magic anymore... so how is he doing it?!"
Charlie who did not know that the Blue Coral chief is using his own remaining life force to cast one last magic, frantically looked for ways to stop him.
"Shoot him!"
"We can't! He is outside the ballista's range!"
As he quickly think of a way, Charlie saw Anise with a glance trying to go forward to rescue the frozen gargoyle whose time run out.
"ANISE!!!"
In the nick of time, both Anise and Aldo junior were thrown away by Lexi who used up all his remaining energy to cast that magic.
"FUCK OFF, YOU BASTARDS!!!"
With the chief's magic shield gone, the merfolks who were going for Lexi stopped momentarily.
"LERUM!"
"You... guys... are..."
Lexi then fell unconcious after being taken away to a safer place by the trolls.
"Seeing that our army is quickly dying, I might as well take you all with me down to the deepest abyss of the sea!!!"
The Blue Coral tribe chief had his skin tore by his own bones, his vessels ruptured, and his organs in the brink of exploding as he casted his final spell.
"ANANPHELION!!!"
His body exploded as a three headed hydra, made of water, appeared on the river.
"RRRRRRRRAAAAAAAAAAAAAAAAAAAAKKK!!!"
The hydra released a mind breaking screech that knocked out most of the remaining merfolks.
"Prepare another round! It's distance is more than two kilometers!"
The hydra that was about to charge froze in place.
"Hope I'm not too late for the fun"
As if ray of hope was bestowed upon them, they became relieved after seeing Aldo back.
"Take care of the remaining merfolks. I want to play with this one"
"H-how will you do that?"
"I'm a game designer. But I love leaving easter eggs, so I also know how to hack another person's program!"
