Calamity Upon This World

"What\'s wrong, feeling scared of a kid?" William asked as a wicked demonic smile found its way on his face.

"Step out of it; he\'s just a kid," Zaratul said as he shook Baratul\'s shoulders, trying to snap his brother step out of his trance state.

"Ah, yes, my bad," Baratul replied, finally waking up from his trance.

Finally, both men summoned a silver cutlass sword from their storage rings.

Baratul prepared his stance as he leaped towards William at an impossible-to-follow speed, even for William.

However, just as Baratul was about to reach William and slice his head off, he stopped right in his tracks as an extremely thin line impossible to trace appeared all over his body.

The next instant, before Baratul could even react, his body was sliced from where the lines appeared as his body parts fell apart on the ground.

Baratul had died, and before his blood or flesh could sully Williams clothes, a thin mana barrier appeared between them.

A 10-year-old had killed a veteran assasin with many years of experience, taking  life without even moving from his spot.

It was an unbelievable thing to believe, but alas, it\'s not possible for everyone to understand the actions of a genius.

Before the fight even began, William had used his [Strings of Mana] skill, which allowed him to create extremely strong strings of mana that are strong enough to even cut through steel and are almost impossible to see unless one has an extremely high sensitivity to mana or can see mana.

He had created this skill a while ago, back when he was still thinking about ways to efficiently use his wide array of skills and spells in proper combat.

However, despite the strength of the skill, William knew the same skill wouldn\'t work twice, so he undid his skill as he summoned his trusty blade of the Runnera sword as well as a dark hooded cloak that contained the properties of multiple armours he had fed his dark slime just in case.

Now donning a long black overcoat with a hood covering his head, along with thin red stripes running across the cloak and a matte black longsword with red runes on the blade, William looked like a warrior of night who was out for vengeance.

As William held his dark blade in his hand, he prepared his stance before he leaped from his position, prepared to swiftly end the life of his adversary.

Seeing the death of his brother Zaratul showed no emotion, and instead he just smiled eerily as he himself prepared to intercept the white-haired boy before he could build momentum.

BOOOOMMM!!

A loud boom sound was generated as both the blades of the white-haired boy and the brown-haired men met in the middle, with the shockwaves destroying their surroundings and even threatening to send them both flying back.

However, both of them just stood their ground, with neither being willing to back down.

Both the men and the boy kept pushing, trying to overpower each other. At first, they both seemed evenly matched, but that was just on the surface, as William was using a bunch of his mana along with the effects of his mana-enhancing coat just to barely match the strength of Zaratul, who only seemed to be using his  raw physical strength.

In a fair fight, it was easy to see that William was quite outclassed against his adversary,both in terms of pure stats as well as experience and skill with the blade. Thankfully for him, this wasn\'t a fair fight, as a sharp black spike emerged from Zaratul\'s shadow, aiming to wound him.

Which he easily countered by finally using a skill to enhance his strength to send William flying, before using his sword to break the spike heading his way.

As William was flying and was about to hit a wall, he swiftly activated his [Shadow Step] skill to jump in a nearby shadow, creating some good distance between himself and his enemy, as he thought.

\'Alright, let\'s try to just keep my distance from him,\' he thought as he summoned his Chaos servants and Chaos beasts.

William\'s shadow expanded a few metres, and from it, Nox, Golden Sting, and Machak, along with around 20 shadow wolves, manifested and charged at Zaratul while keeping his distance.

Zaratul remained calm as he eyed the beasts heading his way.

Before long, his blade clashed with Nox\'s beastly claws, which he was able to overpower and send flying.

After that, a giant bee stinger made its way towards him but managed to dodge it and used a fireball spell on the golden stinger to send it flying back in pain.

After that, Machak descended on him, planning to crush him, but he just used a (storm blast) spell as a small storm of wind sent Machak flying before it could get too close.

The shadow hounds all charged at him at once, but he was easily able to kill around three of them in less than a few seconds before he jumped in the air and made some distance.

Zaratul knew that his target was a summoner; according to his knowledge, the kid had a Tier IV aspect called Shadow Summoner, which allowed him to create creatures of shadows.

However, he didn\'t expect them to be so strong; if he wasn\'t careful, all the monsters summoned by the kid might be able to end him.

Which is why he used multiple speed and strength-enhancing skills to boost his stats as he charged towards the boy.

Attacking the user was the most common tactic against a summoner, and he had already tested the boy\'s strength and confirmed he was weaker than him.

However, just as he was heading towards the boy, he heard him mutter something.

"[Spirit Ascension:Dual Spirit Fire and Wind]" William muttered.

As soon as his words finished, a dual-colour crown of fire and wind manifested on his head, with the right side being made up of an orange fire and the left being made up of a bright teal colour.

His previous black overcoat was now gone, and he now donned a royal-like orange and teal robe.

On his back, two wing-like objects manifested both bright orange and teal respectably.

His eyes glew an orange and teal colour as the sword in his hand was burning in an orange and teal flame.

Activating dual-spirit ascension was his current limit, and he could only maintain that for a few minutes.

The only reason he was able to use all of his spirits to ascend at once as well as [mana ascension] against his fight against Zephyr was because it was an illusion.

Thankfully, two spirits were more than enough for his current foe as he muttered a spell he only developed a few days ago.

"(Set Your Heart Ablaze) "

As soon as his words fell, Zaratul felt a slow heat rising up in his chest, which before long devolved into a full-blown fire emerging from his insides. Before long, his whole body was engulfed in a violent fire.

"Ahahaahahhahaha" He screamed; however, his screams fell on deaf ears.

Before long, he was unable to scream, not because he was dead but because his voice box had been burned off.

Thankfully, after a few seconds, he finally died as his charred corpse fell on the now-destroyed restroom floor.

Both the assasins had died, with only a boy covered in an orange and teal royal robe, along with a similar-coloured crown and wing-like objects, surrounded by multiple monsters still standing.

After assessing that there were no more threats, the boy undid his transformation as well as cancelling the summons of his Chaos servants and beast.

This was his first intentional kill in his second life; however, due to his experiences in the past, he didn\'t panic.

Instead, he had a disappointed look on his face before he muttered.

"I\'m still too weak." William sighed in disappointment.
