Hello there, Skylinemaster here with the final chapter of The Rise of the First Beasts.

CLAP, CLAP, CLAP

Everyone stared at the source of the noise. The Leviathans were curious as a rift opened up, with Cao Cao and a few other humans stepping out of the portal. The blue portal remained opened behind them, with Cao Cao surveying the scene at hand, a wide smile on his face.

"Cao Cao, how nice of you to join us. Although I don't think you came to be on our side."

Kokabiel grinned, looking at Cao Cao before narrowing his eyes towards a sickly, skelton looking boy at the back of the group.

"What's wrong with him?"

Everyone was thinking the same thing. No Human, regardless of who they are, should be radiating that amount of power. The boy's tall, pale, physique was cracking at the seams due to the power he's body is currently holding.

"Oh, Lycurgus? You'll find out shortly."

With that, Cao Cao and his two companions jumped back into the portal which disappeared in a great flash of light.

Lycurgus, his face stoic for the previous time, cracked an unnerving smile at everyone. He raised his right hand up, with his palm facing away from the supernatural beings.

"This life, was without purpose. I was nothing before Cao Cao rescued me. Gave me an identity, gave me a purpose."

He started laughing madly before he continued.

"..For Humanity, this shall be worth it. My death shall bring upon peace, a new era. They shall remember me, not as my ancestor of Sparta, but the one who cleanse the Earth of Devils, Angels, and the Fallen." He said, making a finger gun with his hand. He shot at the Devils, Angels, and then Fallen, before putting the finger gun to his head. "...I'll see you all in oblivion."

With this, he pressed his thumb and index fingers together.

His body shone with the light of a million suns as a tremendous shockwave rocked the Underworld. Everyone had to shield their eyes from the tremendous light, anyone who didn't had their eyes vaporized from the intense luminosity before them.

Anyone realized the danger that they were in tried to teleport out of there, but were blocked due to a barrier. All were trapped in an unfolding nuclear Devils and the Fallen were vaporized due to the immense light. As beings of darkness, they screamed in agony as they were consumed by the light. Their wings were destroyed, leaving absolutely nothing behind.

The Angels were killed due to the shockwaves and the unimaginable heat. The light overpowered their Angelic grace, causing it to curl up and die.

The Leviathans, on the other hand, smiled as the heat disintegrated their bodies, with the shockwave throwing what is left of them into the sky before plummeting back to the ground.

There, in a barren, post-apocalyptic wasteland, stood a puddle of black goo. There were droplets scattered around it, with the furthest being a hundred meters away.

The droplets suddenly flew through the air, and rejoined the puddle of goo. The goo began to rise, taking the form of a young man, before changing into a beautiful woman.

The Leviathan in the form of Rias Gremory, cracked her neck and stretched her body a little bit as she looked around.

She could see the rest of the Leviathans reforming near her.

"Hmm, that didn't kill you? I figured as much."

Cao Cao said as he appeared through a portal off in the distance.

"Nice try through that was really, explosive. What was that?"

Kokabiel asked, genuinely interested in such a powerful weapon.

"Thank you, it was not easy to come up with. What is a soul, hmm? A small ball of pure energy created by God. A ball of energy that can rival a nuclear reactor. Yes, gather enough of them together, use a self-sacrifice spell to trigger to go into a nuclear meltdown explosion for maximum effect, and you end up with a bunch of dead supernatural beings. It wouldn't kill you though, which would have made everything easier. But we'll remedy that now."

Cao Cao explained, rather smugly. Kokabiel smiled and nodded his head at the explantion.

"A soul bomb? How'd you get all the souls necessary for something of this size? And why before the battle? I thought you'd want us to kill each other off before you come in and save the day."

Kokabiel sarcastically said.

"It was rather simple. Hell had a lot of souls that were there for the taking. Those fools wouldn't have been able to kill you. The epic battle would have been a waste of time. Might as well get to the end result faster, shall we? I do have humanity to protect now." Cao Cao said, pulling out a bone in his left hand while pointing the spear at Kokabiel with his right hand."You've outlived your usefulness. Prepare to die."

"Wait, how'd you find us anyways? We've masked our presence, so it be impossible to find us."

Rias said, bring up a valid point. Cao Cao simply laughed and pointed at Georg.

"The river ends at the source, does it not? We knew that you were listening in, all along. An Etruscan spell correct? It was, I admit, difficult to find a spell to trace it back to the source, but Georg managed to find one. Let's just say we let it slip where you were to the factions. And the rest is history."

Cao Cao proudly explained.

"Wipe as many of them out with a nuclear weapon, then kill the survivors, you. I thank you truly, for allowing this to happen. I will be the one to rid all of you beings from here, to protect humanity."

Cao Cao continued.

"Why go through this trouble? Hmm, we could have worked together. You could have locked up Hell and we'd have gotten Heaven, in due time. Also, good on you for creating that bone. Must have taking some arm pulling to get all the blood need for that."

Kokabiel said, glancing at the bone in Cao Cao's possession as he tilted his head at Cao Cao, before a sad, pitying smile appeared on his face.

"I know what it is...Unchecked ambition, your pride and arrogance. I admire your tenacity Cao Cao. The little Human that was touched by God, the one that could. You should have not overstepped your abilities, you little maggot. You'll never defeat us."

Kokabiel taunted. Cao Cao simply closed his eyes and sighed.

"I agree. My pride is honor. I will not have pride with honor as long as there are things that threaten humanity. As for the Angels and Devils, cut off their leadership. Look around you, the Viceroys of Heaven and Hell are here. The Pillars of Hell and the Lieutenants of Heaven, converged here. New leadership will arise, I'm sure. Chaos before unity, war. Civil wars in Heaven and Hell, rival factions vying to take up the mantle. I frankly don't care, have them kill each other off for the rest of eternity, if that is their wish. The gates of both will be sealed up after your deaths, and they will be too busy killing each other to find out how to undue them for a while. Chaos in Heaven and Hell, peace on Earth. We'll have succeeded. Now it is just you and the Monsters, which will fall down like a house of cards. So in essence, you. You're strong, I can see that. All the more reason as to why you need to die. Your deaths will pave the way for humanity's everlasting peace."

Cao Cao said, looking at Georg and Leonardo beside him. Both of them nodded at him. He acknowledged them before turning back to the Leviathan.

"Enough of this. Time to die. Georg, if you will."

Georg nodded as he and Leonardo began to chant.

Cao Cao extended his True Longinus at the nearest Leviathan, which was Penemue. She launched a Light spear at him, to which he easily dodged.

Clouds suddenly formed above the battlefield and a downpour began on the battling forces.

"Argh!" "It stings!" "This again?!"

The rain of Borax hurt the Leviathan, melting through their skin as they screamed.

Cao Cao took advantage of the hurt Leviathan and stabbed Penemue in the stomach with the bone. Penemue stumbled back, in shock at being stabbed with a Bone of the Righteous Mortal.

Black waves emitted from Penemue as she started to laugh. She tried to lunge at Cao Cao, but missed as the human jumped back. The downpour caused intense pain for several of the Leviathans, who were in too much pain to move as Penemue exploded in a torrent of black goo.

"Interesting. It takes them with her as they die. Good to know."

Cao Cao said, narrowing his eyes at the 4 remaining Leviathan. Kokabiel, Rias, Dracula, and Ares, who was recovered from the rain of Borax, stared at each other before staring at the smug Human that just killed several Leviathan.

"You're out. Nice try though."

Kokabiel said, laughing as Cao Cao brought a dagger. The dagger was with an ornate pearl handle, with the blade being made of bone. The knife was no larger than 6 inches in total length.

"You know, the first was just to see if you would die. I got enough of these to finish you off."

Cao Cao said, throwing the blade at Ares, who dodged it easily.

"Chop up the bone enough to make several blades. The tablets didn't say that the bone had to be intact."

Cao Cao joked, pulling out another dagger. He rushed at Dracula, who tried to slash at him with his claws.

Cao Cao parried the attacks with his True Longinus, before turning around to push Ares away with a kick to the stomach. Dracula managed to hit Cao Cao in the chest, causing the human to wince in pain.

The human managed to spin around, stabbing Ares with the True Longinus before stabbing him with the dagger. Ares tried to pull it out as waves began to emit from him, but to no avail. He disappeared just as Cao Cao jumped out of range to be sucked in.

Cao Cao backflipped before landing on his feet, facing the two remaining Leviathan.

"I'm lucky, that explosion took out the other one."

Cao Cao said, sliding the True Longinus over his shoulder with his sling as he took out two daggers. He held the blades in a reverse grip as he lunged at Rias, who jumped back in surpise. Kokabiel tried to stab him with a light spear, but Cao Cao slipped his head away at the last minute, causing the blade to nick him in the face. Blood dripped from Cao Cao's face, but the human ignored it, punching Rias in the stomach before trying to slice her throat with the dagger.

Rias stumbled back from the punch before catching the Human's wrist. She easily held the wrist, preventing Cao Cao from pulling back or stabbing her. The Human headbutted her, causing her to pull back, allowing him enough time to thrust the dagger in the Leviathan's stomach.

He smiled at Rias's stunned face as he twisted the dagger in her stomach, causing her more pain. The human push kicked Rias back as he rolled to the side to prevent being caught in the coming explosion.

Cao Cao continued to roll, avoiding Kokabiel's light spear thrusts at the ground. Kokabiel's spear was kicked away, allowing Cao Cao enough time to get to his feet to face the leader, the last Leviathan left standing.

The two said nothing to each other as they circled each other. Cao Cao pointed a dagger at Kokabiel, who in turn pointed a Light spear at the human.

Cao Cao circled the other way, before zig zagging at Kokabiel as he lunged in with a wide slash.

Kokabiel prevented getting hit by blocking the arm with his arm. He released the light spear he was holding to punch Cao Cao three times in the stomach before hitting him in the face with an uppercut.

Cao Cao spit blood at Kokabiel, who grinned. The human stepped in with a kick to the leg, as he tried a stab to the face. Kokabiel slipped his head to the side, which was Cao Cao wanted. The human suddenly rotated his upper body, spinning around to stab Kokabiel in the side of the face.

Kokabiel grabbed Cao Cao in a bearhug before the human could get away. Cao Cao tried to get away, but the Leviathan's grip was too strong.

"Cao Cao!"

Georg and Leonardo said as they moved towards Cao Cao.

"Stay back!"

Cao Cao shouted. He knew what was going to happen. Kokabiel started to laugh maniacally as Cao Cao saw the black waves emit from the Leviathan who was holding onto him.

"Hehe. I'm taking you with me!"

The last thing Georg and Leonardo saw was Cao Cao closing his eyes as a sea of black came over him.

"...What now?"

Leonardo asked, tugging at the magician's sleeve.

"Let's finish what he started. He would have wanted us to close the gates."

Georg said, turning around and walking away. Leonardo stared at the spot Cao Cao was last at, before turning away and following Georg.

"Do you think he'll come back?"

Leonardo asked. Georg stopped and mused the question. He turned to the younger boy, a slight smile forming on his face.

"He always does."

Thank you for sticking around this long.

Please review and see you in my other works.

Until next time, Skylinemaster out.
