Demon Lord's Reincarnation

When Ren answered the princess with an affirmative he shrugged his shoulders and turned around. The princess who saw Ren was walking away felt relieved. She was unsure if her proposal would even get through to him. Now watching him walk away, Ashley thank whatever God was helping her. As she was about to turn around and talk to Rika, Ashley suddenly felt a weird aura.

It was not mana nor was it a sword aura it was something else entirely. Ashley started searching for where the weird aura was coming from, it was at that moment she felt a sharp wind pass by her cheeks. Her beautiful white cheek had a little cut and was now bleeding.

She looked at the person who attacked and saw Ren was now pointing his scythe at her. Ashley was still unable to understand what happened when suddenly it started to rain. At first, she wasn't bothered by the droplets but then the downpour became heavier. That was when Ashley noticed that it wasn't water that was falling from the sky it was blood.

"You know on second thought I change my mind. Though I do think governing a kingdom to be bothersome... But those who attack what's mine all deserve to die."

Ashley who heard what Ren said looked behind her. The body of her older brother had exploded from that attack not only him even the soldiers that were close to Reynold's unconscious body all burst into a rain of blood.

"I don't need him to sit on the throne, Iselv would fit just right... Or if you want you could be queen. Think about it, while I clean up the trash."

Ashley was about to give her answer but Ren was no longer there.

...

The fleeing soldiers were still running for their lives when they suddenly heard someone whisper in their ear. "Do you really think that you can escape? If you have stayed and fight, I would've considered you guys joining my troops, but seeing you flee in terror like this all of you should die, [Shadow Bind]"

Hearing Ren's voice whispering in their ear the fleeing men started to run even faster. As they tried to flee further away they noticed that they could no longer move. A black shadow had surrounded them binding them to that one spot.

"As expected that guy wasn't good in a one on one match but his skills were meant for large battles against multiple foes." Ren who used one of his past incarnations skills for the first time was amazed by its effect.

When he fought the weakest of his incarnations after powering up his mana, he noticed that most of that incarnation's skills were meant for a battle such as this. This might be the reason why he was considered the weakest among the incarnations since most of them were powerful not only in group battles but they were especially powerful in a one on one scenario.

While Ren was casually walking towards the now stunned soldiers, he noticed that some of them got away from the shadow bind. Ren wasn't bothered since no matter how far they run they can never escape from him. Ren then proceeded to behead all of those that were bound by his skill. Once he was done with that, Ren proceeded to chant some spell words.

"Hear me o spirits of icy frost. Show me thy bone-chilling might. Show me thy will that not even time itself could thaw. Show unto my enemies the unforgiving ice! [Eternal Ice Prison]!"

Ren used another spell he acquired from the past incarnation he beaten. Ren used his mana sensing to spot the fleeing soldiers. Once he was done chanting the spell words he activated his spell targeting those fleeing soldiers.

...

The soldiers who were running away could no longer see Ren behind them. They were also pretty far away at this point, and they even scattered and were running away in different directions. Surely some of them would be able to escape from that monster.

As they were running they felt the air around them suddenly turning colder and colder. Their movements were now slowing down as they could feel their bodies slowly freezing. Then out of nowhere, they were all encased in ice.

...

Thousands upon thousands of crystal coffins sprung from all over the place. Each one trapping a fleeing soldier. Such powerful tactical level magic was done by one person. Those that knew Ren were already expecting him to do something like that. On the other hand, those that only heard rumors about Ren were both amazed and scared as they witnessed the scene before them. Such a young man was able to use such a powerful spell, what kind of monster will he become if he grows further.

...

Ren who had confirmed that he was able to encase every soldier that tried to flee, was now thinking about what to do next. He could kill them using the scythe so that they could become a part of his mana pool, but moving towards each one of them and killing them one by one was too bothersome.

'It's not like killing these weaklings would help increase my mana that much. Let's just end it all in one swoop.'

Ren extended his hand forward and clenched it, "[Break]." The moment he did that the ice that were encasing the thousands of soldiers started to crack. After a few more second the ice broke into millions of tiny pieces. The deaths of most of the soldiers and mages that attacked New Grenton happened in but an instant.

Still, there were some Ren deemed worthy to be kept alive. Those people were now unconscious unaware of the hardships that they were about to go through in exchange for being spared.

...

Once he was done killing those that needed to be killed Ren returned to where the sword princess was. He then looked at Ashley and saw that she wasn't shaken by what she just witnessed. Ren smiled at her before asking, "So what do you say?"

Ashley smiled back at Ren with confidence as she already knew her answer even before Ren darted off. "Being queen doesn't suit me, you can give the throne to my supposed brother Iselv. I don't really care that much as long as the Reschbeauch kingdom can survive. Truthfully I don't really like the current nobles of the kingdom, only my father was acceptable. So removing those cocky old b*stards from their high horses is very much welcomed." Ashley shrugged her shoulders no longer caring about anything. Witnessing Ren's power she knew that keeping up appearances doesn't really matter anymore. Rika who heard Ashley's answer was surprised by how the princess was speaking.

On the other hand, Ren upon hearing Ashley's answer couldn't help but laugh. He then looked at Ashley and asked a question while extending his hand.

"I didn't fulfill the conditions of our prior agreement and created a new one. Knowing this, do you still wish to be mine?" Ashley grabbed hold of Ren's hand and answered with a charming smile on her face, while she was emitting her sword aura.

"It would seem that you're the only man who can handle me, so I'll be with you until you can no longer control me."

"Then you'll be with me forever," Ren answered while overpowering Ashley's sword aura with his own.
