How to become a Demon Lord: The Former Hero's Journey as a Demon Lord!

Rosavellt was still trying her best to fight off the horde of familiars, but there was only so much that she could do since she didn't have her own Resonance yet! If she had her own resonance, then it would be easy to counter this attack! Her resonance wouldn't be incomplete like Reginald's, instead, it would be a complete [Magic Resonance] and there is no way that an incomplete Resonance will be able to fight against a complete one!

Rosavellt could also forcefully create an incomplete Resonance if she wanted to, but she knew just how dangerous it is for your Mana core. Forcing an incomplete Resonance will make it harder for you to use normal magic afterward! She wouldn't do something so stupid!

Reginald smiled wickedly as he saw one of the skeleton knights stab Rosavellt in the thigh! She grunted and fell to a knee as she cursed! The skeletons were too much! How many of these things can Reginald make!?

Rosavellt gave up on attacking and she just held the shield above her as the skeleton knights started to dogpile on top of her! Reginald wondered if he should just make them kill her? I can just tell my uncle that it was an unfortunate mistake. She tried to kill me first and that was why I couldn't hold back. That sort of excuse will surely be enough for uncle!

[Flash Freeze]

Reginald looked up in shock as the entire cave began to freeze over all of a sudden! The water in the middle of the cave froze into solid ice and even the skeletons on the ground froze and they couldn't move again! Then everything cracked and disappeared into snow dust as his entire magic construct was destroyed! Reginald's eyes were wide as he looked around him. What the hell is going on?

Once the cave disappeared, they appeared in the guild house again and Reginald saw two men standing in the guild house. One was a young man with white hair and red eyes and the other one was a bored-looking man with blue eyes and blue hair. Reginald immediately knew that the two men were extremely dangerous! He could just feel it! He could feel a lot of power coming from that blue-haired man, but he could feel as much power coming from the white-haired one. He could also feel a lot of demonic power coming from the white-haired man. There is no way. Is this the demon lord!? This child!? He doesn't even look a day above one hundred years and I can feel that he is not even trying to hide his age! He is only twenty years old!?

Floid walked forward and stood in front of Rosavellt. She was trying to get herself up from the ground while healing her injuries, but once she saw her master she immediately froze. Floid had a slight frown on his face as he looked down at Rosavellt. Rosavellt didn't know what that look meant, but she knew that it was shameful for her to show her loss to her master. Rosavellt immediately looked down.

Floid noticed that her clothes were torn and she was injured but he knew she would be fine after some healing spells. She should have called for help. Why didn't she ever think about calling for help like I told her to? It was Dracula that informed me about what was happening here through a communication circle. Dracula arrived at the town a few minutes ago and he noticed that there was a fight occurring. Dracula knew that Rosavellt couldn't handle any form of Resonance yet and so he immediately called me. Rosavellt could have easily called me a long time ago.

The moment she realized that the enemy in front of her is too much to handle then she should have either run away or called someone to help her. Not calling for help was her most idiotic trait. Even back in the castle when she is doing her job as a maid, she will always try to do everything herself and she never asks the other maids for help.

Floid was feeling a lot of annoyance towards Rpsavellt, but he didn't know that the annoyance he was feeling was just another form of worry. He was worried about Rosavellt! When he saw her state, he knew that she would have died if he didn't come so quickly! But Floid isn't used to caring about people so the only emotion he recognized at that moment was annoyance!

....

​ Reginald was standing behind Floid and he was watching Floid, but Reginald didn't even dare to attack. Dragonnel was staring at Reginald with an intense look and Reginald knew that Dragonnel would attack him if he even moved a muscle. Reginald looked towards Floid again and wondered if this was really the demon lord. He was so young! Too young! Someone like this is a toddler in Reginald's eye!

Reginald watched as Floid said something to Rosavellt and she grit her teeth as she looked down in shame. Reginald could tell that it was something disapproving! Was Rosavellt being scolded by a child!? Reginald felt like laughing his ass off!!

Floid then took off his coat and put it on top of her shoulder and Rosavellt looked up sharply in shock!

Floid was wearing a simple black shirt and trousers so he didn't need the coat, but it was still a big deal for Rosavellt that the demon lord used his coat to cover her! Floid told Rosavellt to stand up and step back to Dragonnel and Rosavellt nodded and simply stood and stepped back. Her leg was still hurting, but she didn't even flinch as she moved away because Floid ordered her to step back. Floid finally turned to face Reginald.

Reginald looked at Floid with a critical eye and he tried to figure out how this child was the demon king. He was still doubting it! This demon lord is so weak! I can't even feel any kind of power from him! Is he a new demon lord? A child that suddenly got thrown into the position of a demon lord!? How laughable! I thought the demon lord was a dangerous man that ruled with an iron fist, but it turned out to be a mere child!! Is this the sort of person that Rosavellt went to serve for eternity!? What a joke!

"I don't know what you think you'll do here, Baby-demon. This is a matter between family, don't interfere. Do you think you can handle me if I get serious? You look like you aren't even done sucking your mother's breasts! How stupid are you!?"

Flood only sighed as he looked to the side. It was like Reginald wasn't even worth his time.

"Rosavellt is a member of my household, so that officially makes her family. If you have a problem with a member of my family then you have a problem with me. I hope your low intellect can at least understand that correlation,"

Reginald grew annoyed at the jab that Floid threw at him. Floid knew that this is exactly how the undead would react. Reginald looked like a petty person who always felt like he had to have the upper hand in any situation. If there is ever a situation where Reginald feels like he is not the one with the upper hand, then he tries his best to level the playing field! And that was why Floid wasn't surprised when Reginald immediately snapped his fingers.

[Magic Resonance: Dance Of The Undead]!!

Magic Resonance allowed someone to manifest a power using Mana. The power would be far stronger than anything they could achieve using only skills. Reginald looked towards Dragonnel as he activated his Resonance. Reginald thought that Dragonnel was eh most dangerous person here so he needed to keep his eye on him!

Reginald believed that Dragonnel was the one that froze his resonance the first time. There is no way that child-demon will be able to freeze a resonance. That means that Dragonnel was the person he had to attack first! And since Dragonnel froze his resonance once, Dragonnel is definitely going to be low on Mana now! It takes a lot of Mana for anyone to break a resonance so Dragonnel won't be able to freeze my resonance a second time!
