As we defeated three two of the four powerful bosses there were, we were about to go slay the other two and end this to get to Jeremias!

However, the Cultists remaining over the Crystal Turtle and the enormous Crystal Guardian Rhinoceros Beetle began speaking some weird nonsense, as magic surged from within their staves and bodies.

"You've forced our hand, you abominable monsters!"

"The Souls of our fallen comrades will become our new strength!"

"[Miasmic Monster Synthesis]!"

FLAAASH!

Suddenly, an enormous, Black-colored magic circle covered the entirety of both Monsters they were mounting, as we all saw with horror as the souls of the Cultists we had slain alongside the many monsters we killed flew towards the Cultists on top of the Turtle and the Beetle, an enormous magic circle emerged atop them, as black gooey miasma covered both behemoths and then forcefully merged them together with the cultists themselves?!

TRUUUUMMM!

Souls, flesh, and magic, everything merged with the disgusting black miasma the surged out of the black magic circle, and everything started converging together into something abominably gross!

"What in heck did those guys made?!" Rita cried in surprise.

"Holy shit this is gross as fuck!" Titan said.

"W-What am I even looking at?!" Lily cried.

"Uwaah! Flesh and miasma and countless souls all tied together" Acorn cried.

"I don't think Lily was asking a literal question, Acorn" Sighed Nieve.

"This is the power of the Demon King of Miasma! They're harboring it into creating a powerful chimeric abomination!"

CLAAAASSSHHH!

Suddenly, enormous black tentacles made of miasmic flesh hit the ground. The mass of pulsating flesh, goo, eyes, and crystals growing all over its body began to move. It was amorphous in shape and we couldn't even know what the heck it was at mere sight!

But it surely was enormously strong! The Cultists were not even here anymore, they sacrificed themselves to merge with the two Boss Monsters into this aberration forsaken by god!

And its stats were

[Aberrant Chimeric Miasmic Spawn: Lv55] [Status: Hungry]

Description: An Aberration born from the Miasmic Secretions of the Demon King of Miasma. However, this special entity was born through a special ritual, utilizing the lives of the Cultists and the powerful Monsters, alongside over a hundred Souls to create it.

An Aberration with no proper shape that originally inhabits the Demon King Continent and devours anything it sees with its enormous body. The Liquid Miasma over its entire body can slowly digest anything it touches, draining its prey vitality and mana in the process.

Its weakness is its speed and sluggish movements. Its weight is too heavy and its body too big, it moves at a slow pace. However, it possess great regeneration and enormous defenses. Only by targeting its Miasmic Core within the internal body, it can be defeated properly defeated.

Skills: [Abyssal Great Crystal Fortress] [Abyssal Miasmic Elemental Crystal Projectiles] [Shadow Meteor] [Dark Shredding Storm] [Black Crystal Blast] [Miasmic Water Torrent] [Super Great Defense] [Heavy Slam] [Super Self-Regeneration] [Hastened Digestion] [HP/MP Drain] [Miasmic Ooze]

Title: [Spawn of the Demon King]

"Uuuaaggh! It is deadly strong too!" I cried, as everyone quickly noticed the monster's stats as well!

"LEVEL 55?!" Asked Titan in shock. "W-We are only just Level 45!"

"T-Ten Levels above us" Acorn was about to pass out.

"This is No, we have fought worse things!" Nieve said.

"Yeah We fought that giant snake; she was even stronger than us back then and we won!" Rita said, hitting the ground with her staff, darkness quickly began pouring from her shadows.

"We can win! If we work together." Titan said, quickly feeling motivated.

"I'll help however I can! If it's big, heavy, and slow, it might be very weak to obstacles!" Lily said.

"Alright Let's do this then!" I quickly was snapped back to reality as I slapped my own face with my hands to snap out of my fear. I didn't had any time to be fearful anyways. "However, we have to find a way to not overuse our strength! Jeremias wants us to use all our energy so he can catch us at our weakest, let's not exhaust ourselves too much!"

"Then let me take the lead." Lily said. "My powers are ideal for this situation."

"They are?" I wondered.

"GROOOOOOAARRRRR!!!"

The Miasmic Aberration began to move. Its enormous body was incredibly sluggish, but because it was so big, every step it took would be several dozens of meters. This thing easily surpassed a hundred meters and reached all the way to the cavern's ceiling.

The monster's tentacles began hitting the ground constantly, shaking everything around furiously.

BAAAM! BAAAM! BAAAAM!!!

"That thing's going insane! We have to quickly take it down." Titan said. "Lily, can we trust you?!"

"I've got a plan, follow me!" Lily said, suddenly thinking about something.

"Alright then, let's trust her." I said with a nod. "She's not someone to mess around with things like this anyways!"

We quickly rushed forward over our Familiars, flying above the skies. The Aberration quickly noticed us approaching, as it started conjuring powerful magic it inherited from the Crystal Turtle, but that was now "corrupted" and became imbued with darkness, becoming stronger.

"GROOOHHHH!"

The Aberration's body was covered on black, purple, and red crystals, and they all suddenly began trembling, detaching themselves from its aberrant body that continued making them grow as they flew towards us like enormous projectiles imbued with darkness!

FLAAAASSSSHH!

"This is just a big crystal!"

I began convincing myself to take on the challenge as I shapeshifted my weapon into an enormous pickaxe and unleashed the combined power of Mining at Level 10 and Spiritual Farming Tool Mastery together.

"Even if it's just a thirty-meter big crystal, you're still an item I can mine! HYAAA!"

I jumped in midair by shaping my legs into spring-shaped plant sterns, and swung my Pickaxe with all my strength, closing my eyes.

CLAAAAASSSSSHHHH!!!

My pickaxe quickly reached the crystal, impacting it with great strength! The Crystal quickly began gaining countless cracks all over, shattering into pieces in an instant!

CRAAASH!
