Transmigrate inside a Web Novel as a Side Character.

Two major forces began to clash, creating a magnificent view in the darkness of the night. The brilliance of golden lightning danced across one side, and a dark, towering aura covered the night with its ominous aura.

Soma and the copy began their showdown. Simultaneously, both of them accelerated, but Soma was in the lead in speed because of the buff from his technique.

He arrived in front of the stunned copy before unleashing his straight kick that aimed at his face. But the devil, with his godly reflexes, jerked his head to the side and managed to dodge the kick in time. However, it was not completely avoided because a trail of red liquid streamed down his cheeks, forming a line across his cheeks to his ear.

The copy's cheeks felt throbbed. He realized his cheek was injured. So he stretched his right hand to grab Soma's raised legs. With the current difference in speed, the copy could only grasp air. Soma retracted his legs, and then he began to shift his attack to his fist and launch a straight punch toward the copy faces. A cracking sound resonated within the land.

Soma's punch directly crushed the copy nose, blasting him a couple of meters in front.

"There is more to come".

Then, from there, the flow of battle changed as Soma began to attack the copy relentlessly, giving the copy a hard time catching his break. Punch, kick, elbow, knee, Soma utilized all of his limbs as a weapon and increased the injury on the copy's body.

Every time his attack connected, skin tore, muscles were torn, and bones crushed, creating a creepy rhythm that made the audience knit their faces. The ominous aura from the copy also began to be dismissed as it was being purified by Soma aura.

The copy, maybe tired after being barraged by the storm, as blood began to smear his vision, the copy retaliated, letting out a howl that shook Soma's eardrums, halting him briefly, before he jumped back.

"Aaah!".

Then, from within him, a flash of ominous black lightning began to burst from his skin before it condensed itself, imitating the techniques Soma was doing.

"...How much is his limit of growth?".

Soma suddenly had a hunch that everything must be finished soon, for he couldn't fathom how far the copy would grow. The copy whose power had undergone a change began to strike first. He disappeared from his place and reappeared before Soma, releasing a straight jab. Soma reacted as he thrust his fist forward and clashed with his fist to fist.

A shattering boom resonated as the surrounding area where the battles upheld turned still. A chaotic ripple began to happen around them, blasting the surrounding air. The earth below their feet cracked before being pushed down, creating a crater that gradually got bigger and deeper the longer their power clashed.

However, Soma noticed that the aura from the copy began to dim as he made contact with Soma.

"Haaa!".

Soma let out his howl, making the copy slightly pushed back. The copy stance crumbled, and Soma tensed his right leg. He concentrated every power he got into his legs. His leg let out a crackling thunder that shone in golden light, alarming the copy's upon the danger from Soma's incoming attack.

A straight thrust from Soma's right leg collided with the copy abdomen. Spurting black blood from the copy mouth before he was blasted away from the place and embedded himself toward the crater.

Soma put away his raised legs as he stared at the cloud of dust that covered the copy's body.

"Ahhh!".

The copy managed to stand up as he uttered his desperate shout toward the sky. Above him, the sky, as if responding to his will, began to attract black clouds, gathering at a rapid speed.

Then, the sky above him was completely shrouded with black clouds, with a black serpent dancing across the surface of the clouds, letting out a thunderous roar before its descent toward the copy bathed him with its ominous might.

"Now what? How far is he going to evolve?".

It seems Soma's perception was not wrong. The copy, bathed by the black lightning, came out unscathed while his body was coated with a tremendous force of nature lightning.

Soma felt a tingling danger upon the sight of the copy, perfecting his imitation of Martial Saint's first technique and the complete one at that. He indeed had the power he lent from Martial Saint, but Soma still couldn't fully exert its full potential. There is also a matter about Martial Saint's dismissing power.

He began racking his brain, trying to find a solution to intercept the copy, which is being evolved every time Soma gains another power. Then, when his gaze met with the crazed gaze of the copy, his eyes accidentally caught the sight of the horn on its skull.

"...No time to hesitate".

[Extra Skill Puppeteer activated]

[Extracting the devil's power within you]

{...Kid, what the hell did you do?}

A slightly hoarse and irritated voice echoed inside his brain, but Soma ordered his puppeteer skill to close off the communication between him and the other two being inside him.

[Two opposite forces that shouldn't coexist in one body clashed; the user will receive its backlash]

"Gurk!".

A trail of red began to appear from Soma's corner lips. Soma's body trembled. His eyes, once vibrant and full of life, began to flicker for the power inside his body, crackling with uncontrollable fury.

His hands clenched so hard that an intense searing light of red and yellow began to clash with each other, bursting his veins, tearing his skin and tendons, and letting out a fountain of blood from his pores. Each breath he took felt labored, struggling to contain the immense power within him.

"...This is truly hard".

[Extra Skill Adapt activated]

[Harmonizing the two forces within the user body]

[The power of Holy and Demonic begin to mix together, creating an *****]

"...Finally".

A skill that he believed would help him in the situation appeared, and the searing pain and the uncontrollable force inside him tamed. Soma, with a rough breath, held his gaze high and let loose his harmonized Aura that made the surrounding air scream. His body was wrapped by a black aura that made the space surrounding him crack.

The aura was slightly thinner from the copy, but it radiated a destructive force that made even the space evaporate.

"...This is the end!".

Soma exhaled every hesitation he held within his heart before placing his stance firmly on the ground, waiting for his enemy to react. The copy who saw the Soma exudes his whole body trembling, but he couldn't disobey his creator's wishes, so he grits his teeth and raises his battle spirit while letting out a warcry.

"Aaah!".

The devil, as he is desperate for his choices, accelerates forward while gathering his power on his legs.

"Come!".

Soma calmly observed his opponent's movement, who dashed forward in a straight line. Time stretched infinitely as the copy movement felt so slow in Soma's line of sight. He began to concentrate his whole power on this final strike and was convinced that this would be the end that Soma wanted.

As the copy had already passed the half distance between them. Soma began to make his move.

"Fuu, Third steps…".

In this stretched time, Soma casually runs while holding an immense Destructive power on his right leg. Each time his legs touched the ground, it disintegrated into tiny specks of atoms.

Soma found himself entering the copy range of attack. He planted his left leg firmly on the ground, then thrust his other legs, making the space around him twist.

"...Lightning Strike".

The world muted before the ripple of disaster began to show its roar. A huge black vortex, because of the warped space created upon his leg making contact, stretched far away, devouring everything that stood in its path.
