Epic Of Caterpillar

-----

As the Rainbow Slime took the form of a humanoid woman, she summoned a powerful dark armor, resembling heavy equipment that a Death Knight would use, contrasting with her cute and beautiful appearance. As the armor finished its creation, she quickly took two weapons from the Slime Cores inside of her chest area, she wielded a long and scarlet blade and a blue ax.

FLASH!

With immense speed, the Rainbow Slime, which was a fusion of six different Slimes used its amazing power to pounce towards the Elemental Knight of Fire. As she jumped over him, a trail of several colors was released, which had a high magic density.

David received her head-on, even if she was almost three times his size, he enveloped his body in undying red and orange flames as he raised his blade, releasing a powerful slash made of pure and concentrated fire.

The Rainbow Slime received David's attack as well, covering her two weapons with several colors, she clashed against David's with amazing momentum.

CLASH!

As the Rainbow Slime kept infusing its strength into her attack, David was suddenly overwhelmed by an immense strength, which made his knees tremble, barely having the strength to hold on.

"Everyone! Please give me your strength! Fiery Heart Embrace!"

FLUOSH!

As David shouted these words, all his soldiers looked at him with confident smiles, and strange red energy was released from their very souls, increasing David's stats. Suddenly, his muscles became tougher, his veins pumped blood at amazing speeds, his eyes turned red while releasing undying flames, while his entire hair seemed to be made of pure fire.

"Uuuoooooohhh!!! Inferno Art; Rising Phoenix!"

As David shouted these words, his blade suddenly released immense golden flames that quickly became a blazing phoenix made of fire, which quickly jumped over the Rainbow Slime as it tried to burn her giant black armor and weapons.

"Screeeeecch!"

Suddenly, the six minds inside of the Rainbow Slime quickly realized the tenacity of the beast, as it tightly grabbed their chest, without having a quick way to repel the phoenix, the Rainbow Slime resigned itself to retreat while shapeshifting into a Rainbow Slime, retrieving her armor and weapons.

However, the phoenix followed her as it started shooting blazing feather arrows from its wings, which showered the slime with massive explosions of pure and concentrated Fire Magic.

BOOM! BOOM! BOOM!

In the distance, David's controlled the phoenix with his mind, while infusing MP and the energy that all his comrades and subordinates give to him.

"Rising Phoenix! Attack with everything you got! Inferno Arts: Golden Flames Tornado!"

As David commanded the Arts, the Phoenix quickly received his order and extended its massive wings, which covered over sixty meters each, and released a massive blaze of golden flames, that took the form of a tornado, directing it to the Rainbow Slime.

The Rainbow Slime had no time to dodge as it took the spell head-on.

FLUOOSH! BOOOM!

Just as the fire tornado exploded, suddenly, something strange happened! The Rainbow Slime extended its entire body over the explosion as if it were eating it like a snack!

"Sluuurp!"

In less than three seconds, it ate it whole. And after receiving such amazing power, the Slime's strength increased as its body started to shine in bright colors more intensively.

"Guuuu!!!"

The six Slime minds quickly commanded their body to release the energy obtained into a powerful yellow beam, which was directed towards the Phoenix, completely vaporizing it as it cried in agony.

"Screeeeeech!"

BOOM!

The explosion caused by the Phoenix being destroyed extended all over the battlefield, instantly killing most of the surrounding soldiers that had no meaning of protection against magic.

Their bodies were burned as they agonized in pain until completely turning into ashes.

After seeing this, David's mind took a big hit, suddenly fearing his own strength, as it caused such a catastrophic attack, he doubted for a moment.

This small moment was enough for the Rainbow Slime to take advantage of, rushing towards David like a giant wave of rainbow liquid, it extended its body into tiny tentacles that started to shoot powerful magic spells. Fire Balls, Lighting Strikes, Ice Lances, Holy Light Arrows, and Dark Swords were released from the giant Rainbow Slime tentacles, devastating David's and his surroundings.

BOOM! BOOM! BOOM!

Each attack was enormous and held tremendous power, falling over David's subordinates and turning all of them into minced meat or puddles of blood and bones.

As David spectated the horror of all his comrades dying horribly, he suddenly froze in time, while his powers barely protected him with an automatic fire shield.

However, the six minds inside of the Rainbow Slime quickly noticed David's state and rushed towards him while shooting countless multi-elemental magic projectiles.

Suddenly, the figure of an old wizard jumped in the front of David, as he conjured a massive non-elemental magic shield in mere seconds, without the need of chanting a spell or creating magic circles beforehand.

The massive magic shield protected not only them from the attacks, but all the surviving soldiers too.

The Old Wizard quickly approached David with an angry expression and grabbed the young man's arms.

"David!"

"…"

"David! Wake up, you naïve idiot!"

"Ah…!"

SLAP!

The Old Wizard, although old and weak, held enough strength to slap David's cheek, leaving it completely red.

"Ugh…! Ah! Sir Wallace!"

"David, there is no time to be grieving for the dead, they are gone! Concentrate on the present, currently, our lives are in danger, we must protect our lives and those who we hold dear and are still alive!"

"Sir Wallace! It's true… I'm sorry!"

Just as David realized his mistake, he saw the Rainbow Slime penetrating Wallace's magic smiled with a giant black sword on her humanoid form, as she rushed towards him with tremendous speed.

"W-Wallace!"

"Huh?!"

The Rainbow Slime suddenly appeared behind the Old Wizard as it mercilessly impaled his body with its massive black blade, penetrating its entire chest, which sprouted a massive river of scarlet blood. His innards were completely blasted and so did his heart.

As the Rainbow Slime glanced at Wallace's last struggles, David was once again frozen in time.

"Ah…! Aaaahh!!! W-WALLACE!!!"

Wallace, while looking at David's cries, struggled to say his last words.

"Ggha… Da… vid… B-Be strong… F-For… Every… one…"

While vomiting mouthfuls of blood, Wallace smiled as it glanced towards the Rainbow Slime beautiful face, and suddenly activated several magic circles he had long made inside of his entire body, which quickly detonated all his magic veins into a powerful explosion, that completely vaporized the Rainbow Slime black blade and half of its humanoid body.

BOOOOOOOM!

However, David was too shocked to hear Wallace's words, he was still frozen, with a desperate and pale face, suffering in despair over the death of his friend, comrade, and teacher.

"Aaaaah!!! N-Noooooo! Wallace!!!"

Although the Rainbow Slime took heavy damage from the Old Wizard sacrifice, it quickly began to reform its humanoid body, until it came back to normal in less than three seconds. As it looked with her beautiful face over David's.

"Guuu… That hurts… You, humans, are full of surprises" It said.

David was once again taken aback as he discovered that the terrible monster could speak.

"Y-You can talk…?!"

"Well, it's not like matters, you're dying now"

The Rainbow Slime quickly transformed its left arm into a sharp dark blade as it enhanced its liquid body power and speed, rushing towards David with threatening killing intent.

FLASH!

David, who regained some of his sanity desperately tried to receive the Rainbow Slime attack with his blade, enveloping it in golden flames, as his hair once again transformed into fire.

"Inferno Arts; Phoenix's Golden Talons!"

Just after chanting these words, the golden flames that covered the Fire Knight blade extended almost ten times their size, and quickly transformed into the talons of a fierce bird, with four massive claws, it intercepted the Rainbow Slime Black Blade with ease.

CLASH!

However, the six minds were cunning and quickly extended their right arm into a massive tentacle that absorbed the entire Phoenix's Talon like a delicious snack.

"Sluuurp!"

David was surprised by the Rainbow Slime, which showed the ability to eat his Arts as if it were immune to fire and could even devour it to become stronger! It was a perfect counter for all his techniques.

Since David started training, he has never fought such an opponent that could just eat his attacks, such a thing was never seen possible for him.

"H-How?! Tch! Let's see if you can eat this! Inferno Arts; Blue Fla-"

However, David committed a terrible mistake, thinking that what he was fighting had any type of humanity in it. He thought that it would wait for his attack and take it like a chivalrous knight or the humans he fought every day would.

But this wasn't the case, as the Rainbow Slime didn't await any moment after eating the Phoenix's Talon and released all the energy is absorbed into a massive yellow beam towards David, which blasted him like a bullet into hundreds of meters away.

BOOOOOOOOM!

"Guuuaaaaaahhh!"

David quickly felt its entire armor being completely vaporized as he took the beam head-on, even with all his passive skills making his skin, flesh, and bones stronger, he felt a terrible burn enveloping his entire body, even if he was the Knight that represented Fire, he wasn't immune to it yet, as he hasn't received the complete blessing of the Demi-God of Fire.

After losing consciousness, David was woken up by a sudden chilly feeling that covered his entire body. Which quickly recovered all his burned skin and flesh, and he even felt as if he regained new Stamina and MP.

When he opened his eyes, he found the cute but worried face of the Half-Salamander Girl, which was surrounded by his demi-human subordinates. Suddenly he remembered Wallace's horrible death and the massacre of all his troops due to that Rainbow Slime. It wasn't a dream at all, all of this really did happen.

"Blaire… How are things going? What about the monster?!"

"Sir David! I'm so glad you're still alive!"

Instead of answering his questions, David was suddenly embraced by Blaire's warm arms, as she started to cry on his shoulders.

"Uuhh… W-We escaped! Lady Emma and Beatrice sacrificed their lives for us! That monster was too strong… The ladies knew that something odd was going on as the soldiers began attacking and raping each other… Only us demi-humans were unaffected… The ladies said that the Kingdom was doomed and that we needed to escape! Snif… So, we are going back to your family, and then going very far away! Snif… Snif…"

Due to all this news, David was destroyed inside. The thought of his two beloved wives sacrificing their lives for him made him want to kill himself in impotence over his weakness. Even worse was the fact that he was carried unconscious by his subordinates to quickly escape, saving his life and sacrificing that of the ones he wanted to protect.

David never wanted for others to sacrifice his life for him, but always saw himself as their shield, and that one day he would be the one who would protect their lives with his own.

However, things were different, he barely survived, and while being unconscious, his friends and subordinates sacrificed their lives to carry him towards a caravan, while his two wives fought the monsters on his place, creating some time for him to survive.

David's body was extremely tired, even after Blaire's healing, his muscles itched in pain and he could barely breathe, yet, in his efforts, he tried to move. However, he was received by the bones on his knees quickly cracking and breaking apart, causing him immense pain.

At this, Blaire yelled at him while her tears covered her red cheeks.

"S-Sir David, please be careful, you need to rest! Almost all your bones were completely turned into ashes! It took so long for you to recover, even after using every drop of my MP, it wasn't enough to regenerate your body completely, please rest! Your body is in a very delicate state, you will break apart at any moment!"

"B-But I!!! I need to do something! I can't keep being here, while Emma and Beatrice… I need to save them!!! I can't keep being in here! I JUST CAN'T!"

For the first time, David began to cry intensively, releasing a river of tears, and tightly hugging Blaire. As Blaire, received his sudden embrace, she caressed his back as she slowly conjured a spell to make him fall asleep.

"We cannot let you die, Sir David… You are our only hope…"

Meanwhile, back on the battlefield, a terrible scene unfolded. After an impressive battle were the twins showed their amazing talent and skills, gaining enough time for David and Blaire to escape, the Rainbow Slime managed to defeat Emma and Beatrice, impaling both with a Dark Lance and a Blue Blade.

The power that the combination of Kireina's six Slimes showed was beyond anything these humans have ever seen and were quickly overwhelmed by her might.

The blonde twins died with a happy smile, as the last thing they saw was their beloved husband David escape from this horror.

"David… Please, you must live… Our hope…" Said both, as if they were the same person.

The Rainbow Slime celebrated its win as it quickly digested the twins with its liquid ooze, dissolving them into nothingness in half a minute.

"Hmm…! Delicious!"
