How To Be A Demon lord: The Former Hero's Journey As A Demon Lord!

Once Rosavellt out her hand into the spatial space, Reginald grew even angrier! So she is even going to attack me because of that demon king!? What sort of loyalty does she have!? She is willing to fight her own family because of a child king!! Well, then fuck you! If you won't come with me by yourself then I'll drag you to hell while screaming and crying!

Reginald shot off the ground and Rosavellt immediately pulled her sword out of her spatial space! She knew that he would attack her!

Clang!

The clash of two swords rang out across the entire building and Reginald snarked in Rosavellt's face! He pushed her back and then kicked her with great force! Rosavellt was pushed back a little, but she easily caught herself and brought up her shield as she saw him charging for her again! Reginald slammed his sword against her shield and Rosavellt braced her legs against the ground!

Boomm!!

A deep crater formed under her once she received the attack before she used the momentum of the attack to turn to the side! The shift of balance made Reginald lose his footing and he has to rush to balance himself again!

Reginald felt Rosavellt grab him by his cape, but he immediately turned around and grabbed her hair before sending his knee up to her face!

Crack!!

A great crack resounded across the room as he broke her nose! Reginald jumped back with a victorious smile, but he grimaced when he felt something painful on his right hand! He looked towards it and his eyes widened! Oh, his hand was gone?

Rosavellt stood up and slammed her shield into the ground so it stood on its own. She then touched her broken nose with one hand to activate [Healing]. In her other hand, she held the severed hand of her brother. She managed to cut it off when he rushed in and used it to grab her hair.

Rosavellt has always been stronger than Reginald. Even if Reginald tried to overpower her physically, she was far more agile and she could also use the sword better than him. She knew that she wouldn't lose when it came down to swords. Reginald, meanwhile, scowled at the hand he lost before he used [Healing].

The stump immediately grew into a new hand and he flexed the hand to make sure that it was good. How could he make a stupid mistake like that? He knew she was better at fighting with swords so why the hell is he allowing his emotions to get the better of him? He would have to be more careful from now on.

"I'm just going to keep on cutting you. You can't beat me and you can't run away. So just give up. The demon lord wants me to bring you back to him and if you resist then I'm meant to kill you. And I will. So please give up,"

This was the only time that Rosavellt has ever begged her brother. She knew that if things kept on escalating then she might be forced to kill him. She still hasn't gotten serious in this fight and she knew that he was not the sort of person to back down from a fight, so he will keep on trying to attack her. Even if she was loyal to Floid, she still didn't want to kill her brother without a good reason so she just wanted him to surrender on his own,

But she was shocked when Reginald suddenly put away his weapon. Reginald was looking at her with hardened eyes as he spread his hands and spoke.

"I already knew I wouldn't win against you in a fight. You were always faster than me so I'll give you that win, you cunt. But while you were wasting away as a slave to the demon lord, I've been training. Can you even measure up my current power anymore!?"

The ground suddenly started to shake as Rosavellt felt dread pool inside her heart! Something was wrong! This isn't a skill! Rosavellt would know if Reginald activated a skill since she would feel the mana, and this is definitely not a skill!

The entire guild house vanished and Rosavellt suddenly found herself inside a dark cave! There was a large river running through the middle of the cave and Reginald was standing on the other side of the river.

Rosavellt stepped back before her legs touched the water. She didn't know what was inside that water and so she decided to be careful for now.

Reginald's appearance also changed. He was no longer shirtless. He now wore a long black cloak over his entire body. He had both hands folded In front of him as he looked down his nose at his sister. He smiled viciously when Rosavellt avoided the water. That water was the Styx. If she touched it then she would have suffered the full curse of his magic.

"Magic Resonance? How?"

It didn't take long at all for Rosavellt to know exactly what this was. It was [Magic Resonance]. An advanced spell that someone can only perform when they go past the realm of SSS-class mages. It was a special spell that gave every person a different ability that no one else could possess. Before you can achieve it then you have to possess at least a million MP!

But then how does Reginald have it!? He was still an SS-class! Has he already broken through the million MP mark? No! I would know if he did! He doesn't fight like someone who has passed through the million MP mark! Then how did he get his resonance? Did he do something to himself!? A pat of Rosavellt was actually worried about her brother. It was very bad if someone forced resonance to activate before they were ready! They could die!

The entire room released a deep groan and then it shook like an earthquake was going through it! Roosevelt saw the water speed up and she finally understood that Reginald didn't have full control over this place. He was forcing himself to entire resonance! He is still not strong enough to keep it active.

"Are you mad, Reginald!? What do you think will happen to you if you make a mistake here! This Resonance can kill you!!"

Reginald smiled! He didn't care what Rosavellt says! He knows she is just jealous of him!

"I don't have full control as I should, it's barely an F-rank [Magic Resonance]. But something like this is more than enough to defeat you. It doesn't matter how strong you are. If a regular swordsman goes against a Resonance, then they will lose. You are the first person to see my resonance! [Dance of The Undead]! You'll realize the difference in power between you and me when we're done here!"

Once Reginald said this, Rosavellt felt something grab her foot. She looked down to see a Skelton familiar dragging itself out of the ground with a scream! She used her sword to stab it, but more and more of them just kept on appearing!

Resonance was a power that granted the caster absolute control over one aspect of his ability. When you use [Magic Resonance]. You will only be able to use one ability, but that ability would be stronger than any skill that you can cast without [Magic Resonance]. Reginald's Resonance was named [Dance of The Undead]. Without resonance, Reginald could only summon about two hundred familiars at most, but inside his Resonance, he could summon hundreds of thousands!!

Rosavellt was cutting down skeletons like her life depended on it! They just kept on coming no matter how many she cut down! She had to get rid of the skeletons so she can get to Reginald! He needs to stop this Resonance or he might die of Mana Exhaustion! He doesn't have the strength to make this Resonance yet! Rosavellt got rid of most of the skeletons and she was about to jump over the river, but one of the skeletons managed to grab her leg again and she wasn't able to move out of the way as another one bit her leg hard! She used her sword to stab it in the head and then kicked them away from her!

Reginald just stood and watched. He didn't care how many injuries she got, he just needed to weaken her enough to take her back home. He wouldn't kill her till he took her back to their uncle so she can answer for her crimes!

Reginald was amazed at the power of [Magic Resonance]. Even when the Resonance is incomplete and failing, it was still stronger than an SSS-class mage can handle! How strong will a fully realized Resonance look!? It would be amazing!

Rosavellt summoned her shield and stabbed the end of it into the ground to block one of her blindspots from the skeletons! There was nothing she could do here other than defending! She has probably killed a thousand familiars, but even if she managed to fight off a thousand skeletons, there will still be more and more that come! She used the skill [Flame Arrow] and destroyed ten skeletons that were trying to rush her from the right side before she stabbed her sword into a skeleton on her other side!

Reginald was pushing himself very much to keep the Resonance active but Rosavellt knew that if she can hang in for a while he will eventually run out of Mana. He won't be able to keep it active for long since it is not complete. Reginald still hasn't perfected his Resonance, so he is using a lot of Mana to keep this one active!

Reginald grit his teeth when he saw that she was still fighting very well! Even with all these monsters, how is she still fighting!? He immediately gave a mental command to some of his familiars and a new wave started to appear! The new wave had swords in their hands and Reginald knew there was no way that Rosavellt will be able to keep up with this horde as well!

The former horde of skeleton soldiers was on the same level of physical strength as A-class knights, but this horde had the same strength as an S-class! Rosavellt frowned as the new wave started to rush her! She immediately activated a wide-area attack spell and waited for the right moment to use it! she knew she won't be able to fight all of them in a head-on battle so she has to keep them away from her! The only thing that was keeping her alive was the fact that this was an incomplete Resonance. If it was complete then she would surely be dead already!
