Demon Lord's Reincarnation

Erste was the first to make a move as he raised his sword upward, origin style swordsmanship first form [God Slayer]. Everything in the path of the sword even those in the distance was sliced in half, as it was about to land on Largen, he raised his shield and shouted.

"Sing the hymn of war!"

Largen parried the incoming strike using his shield, and then he threw his spear towards Erste. Everything in the path of the spear was torn asunder, the bodies on the ground were reduced to nothingness.

Erste intercepted the spear with his sword and then deflected it. The very second the spear was deflected Largen appeared in front of Erste and the spear reaped in his hands.

Erste made a horizontal slash which Largen blocked with his shield and countered with a forward thrust of his spear. Erste evaded the spear and tried to grab hold of it, but before could do so the spear's trajectory changed and pierced upward, Erste was barely able to evade that strike.

Erste quickly kicked Largen to make some distance between them, but Largen's shield blocked his kick and pushed him back making Erste unbalanced. Using the single nanosecond of an opening, Largen thrust his spear aimed at Erste's heart, but then Erste lifted his sword and barely deflected the strike and he pushed backward thus creating distance between him and Largen.

Erste regained his balance and got into another stance were his center of gravity was lowered putting all the weight he had onto his sword. Origin style swordsmanship second form [Milky Way].

Erste did a horizontal slash and from that slash numerous tiny stars were born that made the attack look like the literal Milky Way. Those tiny stars then exploded with the power of millions of supernovas.

Just before the explosion happened Largen knelt on the ground and then used his shield to cover his entire body. The explosion that should have broken through this dimension did not do so and the target that it should have disintegrated was alive and well without a single scratch on his body.

"Hahaha! That was amazing, as expected of someone who understands the hymn of war! Now let the voice of our blades make the song louder for the entirety of the omniverse to hear! Let our dance of battle show our utmost praise to war!"

The more Largen spoke the more powerful his presence became, some of the Old Gods who were watching from different dimensions found it hard to remain standing. On the other hand, Erste who was standing right in front of Largen got even more excited as the smile on his face looked even more vicious than normal.

Seeing the expression on Erste's face Largen laughed heartily. This human was the one he had been waiting for his entire existence.

Unlike the other Ancient Ones, Largen did not exist just to find a way for the ORIGIN to praise him. Largen had only one thing in his mind and that was war, but to wage war one needed an opponent. Largen was unable to wage war on his siblings, and it would not mean anything to wage war on the Old and New Gods.

So to him, Erste and his group were a treasure he had been looking for his entire existence.

Erste created several blades made of pure mana. Erste threw each blade to the sky and after a while, they started descending onto the ground. As they descended the swords made of mana absorbed the mana of the surrounding area and grew in size, this was the third form of the origin style swordsmanship, [Falling Stars].

Largen stomped onto the ground making it tremble, and then he got into a throwing position. The muscles of Largen's body tensed up as power started gathering into his spear. Largen threw the spear towards the mana swords falling towards him. The spear pierced through the mana swords like they were paper, but as that was happening Erste had already appeared behind Largen.

Erste had attacked from Largen's blind spot but before his sword could reach the shield once again blocked his attack. Erste who failed his surprise attack backed away as Largen retrieved his spear.

"What's with that shield, no matter what kind of attack I make it seems like you'll be able to block it."

"This spear and shield have no name, but they are the strongest shield and spear in existence. For as long as my heart stands firm my shield will be able to withstand any damage, as for my spear it can penetrate through any defense. This is why I can openly praise you for evading and deflecting the spear, since if you blocked it this battle would end."

"An unbreakable shield and a spear that can penetrate anything. If I beat you will you give me those things?"

Largen looked at Erste with a dumbfounded expression, and after several seconds of silence, Largen laughed.

"HAHAHA!!! You truly are an interesting human. If you're able to win as per the rules of war, the winner takes all."

"I see, then what will you take if you win?"

"I already told you the winner takes all."

Largen threw his spear but this time he didn't aim at Erste but on the ground near Erste. The ground broke and several pieces came flying towards Erste who sliced through each one, but then as he sliced through another one a thud sound echoed as his sword was pushed back. Beyond the dirt, Largen appeared with spear and shield at hand.

Largen's spear was aimed at Erste's head and in his position he would not be able to deflect it, so Erste moved his head. Erste could not fully evade the strike a wound appeared on his neck. Erste kicked Largen's shield but in their current position he could not swing his sword so instead he let go of it and punched Largen.

Largen could not block the incoming strike with his shield and his spear would not be able to get into position fast enough so like Erste he let go of his spear and instead of trying to block the attack also attacked at the same time.

Erste and Largen hit each other at the exact same time, Erste hitting Largen's abdomen and Largen hitting Erste's face. Each other's attacks blew away the two of them. Once the dust settled, Erste's nose was bleeding while Large was puking a bit of blood.

"This was a fun battle, but it seems we could not determine the winner so it's a tie," Largen declared.

"Hmph, it's a tie because you were holding back."

"Well weren't you holding back as well?"

The two who were glaring at each other smiled and started to laugh heartily.

"We might be in different positions and are enemies, but I do not hate you," Largen spoke as he hid his shield and spear while approaching Erste.

"Yeah, I feel the same way." Erste also hid his sword in his pocket dimension. Largen then extended his hand forward and Erste grabbed it, the two shook hands.

"The next time we meet will be the true battle."

"I look forward to it."

That's how the first battle between the two sides ended.
