Demon Lord's Reincarnation

Ren looked half-dead and shouldn't be able to stand much less fight. But the truth was Ren only suffered minor wounds and small scratches. Fean who was given the seed of the ORIGIN was indeed strong, stronger than the current Ren, but that was all he had. He was just a beast with strength. All his attacks were linear, with a lack of techniques or feints.

Even though Ren could barely dodge them, he managed to avoid getting any critical damage. He was only bruised all over, with some minor cuts on his hands.

...

Fean's barrage of attacks was neverending which gave Ren little to no time to catch his breath. The situation was unfavorable for him in every possible way, but instead of showing a negative emotion Ren's face was brimming with joy.

The tension of death if you make one mistake. The concentration needed to find that one chance for victory and the tenacity needed to keep on going even though winning was close to impossible.

It has been ages since Ren felt like this. It reminded him of his first-ever battle against the demon lord before him. Ren at that time was also having a hard battle were he could die at any moment, but the difference in power wasn't as much as this.

'This is it! This was the kind of fight I always wanted!' While Ren was dodging Fean's attacks, he finally unleashed everything he currently had. Though his mana was not as much as the time he defeated Alfred, since the effects of eating the young dragon's heart wore off, Ren's current mana was still much thicker and stronger than his mana when he fought Alfred for the first time.

After unleashing the full extent of his mana, Ren also coated himself with the entirety of his Spirit Aura. Yet even with using the full extent of his current strength, Ren could barely keep up. He was now able to dodge a bit better but that was it. Ren could not find a way to counter-attack but that didn't make Ren feel hopeless, instead, it just got him even more excited.

'If I can't find the perfect chance to counter, then I just need to attack!' Ren decided to no longer bother with evading or defending and went back to his original style that leans more into attacking.

Ren who was covered with mana and Spirit Aura took one of Fean's attacks head-on. After receiving the attack Ren felt like his innards wanted to come out, but he pushed the feeling of pain aside and attacked as well. His fist finally landed a blow on Fean's face. That attack was the best he could do at the moment, but it barely scratched Fean.

The damage dealt and damage received was not in Ren's favor but he continued to fight with that vicious smile of his. The attacks of the two were making the cave they were in that was already cut in half shake by the shockwaves of each attack.

Lance cut any debris that fell his way, while Silika pushed the debris that fell onto her using mana.

...

The battle between Fean and Ren continued as fist and leg hit every part of the human body that could be hit. But then a change started happening. Ren was now able to divert some of Fean's attacks, but every time he did so, he could hear his skin being ripped apart. But Ren wasn't bothered by such a trivial thing as he gave Fean a counter to the gut.

Ren was truly having fun right now, facing an opponent that could overpower him so much was exciting. He was being given incredible damage by the enemy, while he could only give minor cuts onto his enemy. Still, he felt that his martial prowess was actually increasing as the fight went on.

It was at that moment when he was finally able to evade and divert an attack perfectly, Ren took that chance and kicked Fean's head. He placed all of his Spirit Aura he had surrounding his body into the shin of his legs, he even used all of the body enhancing spells he could use at the moment and focused it all on his legs.

That strike of Ren's was able to blow Fean's body onto the wall even drilling through it. Of course, Ren didn't let his guard down, but then Fean did something out of the usual.

Fean like the beginning once again charged at Ren. Ren who saw the incoming Fean was about ready to parry and counter, but then the attack Ren was waiting for turn out to be different. Fean who was using his hands and legs awhile ago suddenly used his teeth to attack.

Ren didn't see that coming and wasn't able to evade in time. Fean's teeth sunk into Ren's shoulder. Ren then tried to pull Fean away from him, but Fean hugged him tightly as his teeth sunk even deeper into Ren's shoulder making it bleed like a fountain.

Ren could easily push Fean by using a spell, but except for the time he used one spell to cushion his landing, Ren never used any spell aside from body strengthening. He already regretted using the wind spell at the beginning, so he decided that he wouldn't use any spell that wasn't body enhancement in this kind of fight.

So instead of using a spell Ren started to headbutt Fean repeatedly until he finally let go of Ren. Once there was some distance between them Ren punched Fean in the chest pushing him a few feet away.

A chunk of Ren's shoulder was bitten off, and his head was now bleeding profusely which got into his eyes and blurred his vision. On the other hand, Fean only had minor wounds on his face and a few bruises on his chest.

It was at that moment Ren sighed. Fean once again went into his offensive, but this time Ren retreated a bit.

"Lance hand me a sword!"

Hearing his master's voice Lance reacted almost unconsciously and threw one of his swords at Ren.

After Ren caught the sword he stopped retreating and took a stance. The sword was inside the sheath and Ren took a deep stance.

Fean who saw his opponent finally stopped retreating charged at Ren at full speed. Ren who saw the incoming Fean stabilized his breathing then muttered.

"[Moon Edge style- Cresent moon]" Fean who was charging at Ren missed his target, and was about to turn around and attack. Fean was going to use his right hand to swipe at Ren, but he could no longer feel his right hand. Even though he was in a frenzy Fean unconsciously looked at his right shoulder. Blood started spurting from Fean's right shoulder.

Lance was amazed to see Fean's right hand was on the floor. No one could see Ren even draw his sword, not even Silika was able to follow the attack Ren made.
