A New Demon Lord

Rimuru was thinking about starting his favorite hobby—naming monsters—when Great Sage spoke in his mind, interrupting his thoughts with its usual calm yet analytical tone.

Master. The 200,000 Orc bodies remaining on the battlefield can be used as a sacrifice to summon powerful demons. A strong demon could be a valuable addition to your forces."

Rimuru nodded. "Great idea.

Rimuru returned to the battlefield, where the 200,000 Orc bodies lay scattered. His generals—Benimaru, Shion, Souei, and Madox—watched as he prepared to use his unique ability.

"Rimuru-sama, what are you planning to do?" Benimaru asked, curious about the sudden change in atmosphere.

"I'm going to summon some demons using these Orc bodies. They'll be useful for protecting the village, especially while I undergo my evolution."

The generals exchanged glances, impressed by Rimuru's boldness. Shion smiled brightly. "Leave it to you, Rimuru-sama, to turn even corpses into allies!"

Rimuru chuckled. "Well, it's a waste to leave them lying here. Might as well make good use of them."

With a wave of his hand, Rimuru activated Predator and began absorbing the Orc bodies. They vanished into his Stomach one after another until the entire battlefield was clear.

Rimuru returned to the cave where he first awakened as a slime. The air was heavy with anticipation, and his generals stood watch outside the entrance, ready to protect their leader from any interruptions. Inside, Rimuru collected the remaing souls then The VOTW made an announcement:

NOTICE: THE HARVEST FESTIVAL FOR THE INDIVIDUAL RIMURU TEMPEST IS ABOUT TO BEGIN."

Rimuru, feeling the pull of sleep as his evolution began, struggled to stay conscious.

He extended his hand and chanted, "Hear my call, demons of the abyss. I offer 200,000 souls and bodies as tribute. Come forth and serve me."

A dark vortex appeared, and the temperature dropped sharply. From the portal, three demons emerged:

A crimson-haired demon with piercing golden eyes and a sinister smirk.

A muscular blue-skinned demon, radiating raw physical power.

A black-haired demon with eyes as dark as night, faintly glowing with gold. He stood calmly, his presence unnervingly cold and calculating.

The black-haired demon stepped forward, his gaze sharp. "Such an offering… This is no ordinary summoning. How can i serve you?"

Rimuru, already feeling the pull of sleep, struggled to remain conscious. "Prove your strength. Protect my village while I undergo my evolution."

The demon bowed. "Consider it done."

As Rimuru fell into a deep slumber, the Voice of the World echoed:

"NOTICE: THE HARVEST FESTIVAL HAS BEGUN FOR THE INDIVIDUAL RIMURU TEMPEST."

"BODY RECONSTRUCTION: TRANSFORMING INTO A NEW SPECIES."

"TRANSFORMATION FROM SLIME INTO DEMON SLIME COMPLETE."

Guy Crimson (Ice Continent)

In his grand palace of ice, Guy Crimson, the strongest of the Demon Lords, leaned back on his throne, a mischievous smirk curling on his lips.

"A new Demon Lord, huh? Rimuru Tempest... Interesting. I'll have to pay this one a visit. He might even prove to be a decent challenge."

Deep in his Castle, Clayman was seething. He slammed his fist against his ornate table, shattering it. "Impossible! My plans were flawless! How did this upstart slime manage to ascend?!"

Tears of frustration and rage streamed down his face. "Gelmud's failure was just the beginning. I'll make sure this Rimuru pays for ruining everything!"

In the Beast Kingdom Eurazania, Demon Lord Carrion sat on his throne, stroking his chin thoughtfully. "A slime ascending to Demon Lord? He must be stronger than I thought. I might have to send someone to check him out."

Meanwhile, in the Sky Queen Frey's territory, Frey gazed out over her kingdom, intrigued. "Another Demon Lord... This could upset the balance. I wonder how Milim will react to this."

Milim Nava laughed gleefully. "A slime Demon Lord? This sounds fun!"

After receiving their gifts, the generals fell asleep.

After a little while, Rimuru woke up, he clenched his fists and felt the overwhelming surge of power coursing through his body. His gaze hardened, and a grin spread across his face.

"Let's see what this Demon Lord is capable of."
