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

"Prepare for combat!!"

Dulla shouted out to all her soldiers and the formation tightened. They all pointed their spears towards Floid and their shields were gripped tightly until their knuckles turned white! They could only see one man in front of them, but from the way Dulla was shouting, all the men in the army knew that this man was dangerous! They just waited and anticipated Floid's move!!

[Bloodlust]!!

Then all of a sudden, Floid released his BloodLust! A wave of hatred blasted into the army and their knees shook! The bloodlust was thick enough to choke on! Floid's bloodlust was stronger than anything they had ever felt in their lives. Even Dulla was stunned for a moment as she tried to slow her heartbeat down! What is this!? This can't be the bloodlust of a single man!

Floid continued to feed more and more mana into his bloodlust skill and the army under him started to doubt themselves! The bloodlust that he was released was at least EPIC-class and it was still rising!

The army had no idea how strong Floid was, but with his bloodlust alone, they could only guess that he was higher than EPIC!!

But Floid wasn't higher than EPIC-class. In fact, Floid wasn't even EPIC-class at all. Floid was only an SSS-class. But his unlimited Mana allowed him to cast his bloodlust skill at a level that was higher than his class and so the army below was already starting to doubt themselves! Asmodeus started absorbing Mana at an immense rate and Floid tightened his hold on it. His Title as the [Virtue of Content] allowed him to absorb Mana at a rate that was 20% faster than before so Floid could feel his magic core expanding and contracting very quickly! Floid kept his BloodLust active for a few more seconds before he finally made a move as he took a giant leap off the mountain!

Boom!!

Dulla was one of the only soldiers that reacted in time and she shouted out to the other soldiers and told them to brace themselves! Floid landed like a comet in the middle of the army! Just his landing killed more than ten soldiers and hundreds of them were thrown away by the shockwave! Floid didn't waste a second before he began to fight.

Phwoom!!

From the very beginning, Floid already used his trump card. For the past month, Floid has been making research about the best skill to use against the undead and he found out that the former demon lord used the skill [Internal Combustion] when he was fighting against the undead during the war! Floid easily copied the skill from Alucard and he trained it to the point where it could be considered an SSS-class skill on its own!

Immediately Dulla saw yellow flames leaking from around Floid, she knew that there was something wrong! Was he going to use a fire-based skill? Dulla knew that Fire-based skills were dangerous to the undead, but that doesn't mean they are helpless against it! If Floid uses [Blessing of Fire] then we don't need to be worried. Every undead is taught how to counter that skill once they join the army and they can easily counter it.

But Dulla noticed that there was something wrong with the skill. [Blessing of Fire] was a holy skill and so it was made up of white flames, but why is this flame yellow? Dulla's eyes widened once she realized that she got it wrong! This isn't [Blessing of Fire]!!

"He is going to use [Internal Combustion]!! Raise your shields!!"

Dulla shouted this frantically to everyone but it was already too late!! A lot of the soldiers close to Floid were disoriented and they weren't able to bring up their shields fast enough as Floid covered his sword in fire and he swung it!! The aftereffect was like a solar flare!

A wide arc of fire shot out from the sword and traveled through the army! The lucky few that were able to bring up their shields were able to survive the attack but those that were very close to Floid screamed as their entire body was engulfed in the intense fire! Floid dashed forward with his flaming sword and Dulla screamed for the remaining men to attack!

[Advanced Sword Arts]

[Ice Lance]

[Flash Freeze]

[Horizontal Slash]

Floid clashed with the army and he used skill after skill to destroy tens of enemies at once! The army was all running towards him, but since he was only one man, they couldn't swarm him all at once! Floid was destroying all the enemies around him before he would use the [Internal Combustion] to destroy another large number of them and create more space for himself! There was a lucky soldier that managed to get close enough to stab Floid in the back, but the soldier didn't even get to enjoy the victory before he was impaled by an [Earth Lance]. The injury on Floid's back started to heal immediately and Floid never stopped fighting!

[HP: 3500(+5900)/3500(+13000)]

[MP: 2,100,444/3,700,000]

The [Virtue of Content] title gave Floid an additional 50HP temporarily for every 100HP damage he dealt to an enemy! That means that the more people he kills, the stronger Floid becomes for that fight. After killing more than five hundred enemies, Floid had gained more than five thousand HP. All the damage that they were dealing to him was shaving away at his HP, but Floid was also gaining HP at a phenomenal rate so he wasn't even bothered by the damage!

Floid stabbed his sword into the throat of a soldier in front of him and he slashed to the side and sprayed the soldier's blood into the eyes of the other soldiers by the side! Floid then used them as a shield to protect himself from a low-level water skill that would have hit him. The soldiers were thrown to the ground and they were not able to stand up before they were trampled by other soldiers that were also trying to get to Floid! Floid activated his [Internal Combustion] again and he felt his heart heat up before flames surged to life on his sword.

Only two more left.

Even though Floid already learned the skill, Floid couldn't use the [Internal Combustion] skill more than five times before he would cause serious damage to his Mana core. The [Internal Combustion] skill was very strong and even though his core was already very large, it was still not able to withstand that much Mana surging and burning through it.

If only I had Givalich, then I would have been able to use this skill infinitely.

Givalich was the dragon of fire, so it would give Floid the ability to use all flame-based skills without repercussion. Floid would have been able to cast [Internal Combustion] forever if he wanted! But for now, Floid will have to make do with only this much.

Phwoom!!!

Floid unleashed the skill and the fire surged straight towards the army, but a large stone wall rose from the ground and protected them as Dulla finally arrived at the front as well. She has been trying to get to Floid but there have been too many men in her way and she finally managed to find her way through. Once the stone wall blocked his skill, Floid shot his hand out and activated [Flash Freeze]! All the undead that were protected before were immediately frozen in a large block of ice and Flood threw his sword like a javelin and allowed it to slam into the ice! The ice broke and all the people inside were shattered into millions of pieces. Floid gave Dulla a condescending stare. Who the hell do you think you are trying to protect? Did you think I would let you protect someone that I'm trying to kill?

Dulla roared in anger at Floid and she charged in with her sword held high! Floid dodged her swing and kicked her back. She turned around and used her sword to throw up dirt into his face! Floid dodged it and he kicked her away when he felt that she was gathering a large amount of Mana.

Dulla was about to unleash a skill, but when Floid kicked her back, her skill was sent to the side, and the wave of electricity that she released destroyed some of her own men. Dulla got her feet back under her and she wanted to run in again, but a wave of electricity from Floid suddenly slammed into her chest! The shock that passed through her was immense and she blasted back into the crowd!

Dulla was stunned! She coughed and a blob of blood fell out of her mouth. Her right hand was shaking and she didn't think it would stop anytime soon. The skill that Floid just used was her own. How was he able to use her skill against her!? And not only was it the same skill, but it was also even stronger! Dulla struggled to her feet and she saw that Floid wasn't even paying her any attention once he got rid of her. He was busy decimating her army. Floid coated his sword with fire again and he used [Internal Combustion] to kill hundreds of men! The fields caught on fire and it became hard for anyone to see because of how much smoke was rising in the air. The men were trying their hardest against Floid and some of them were even managing to hit him, but no matter what they did, he would retaliate with even more force and he would destroy them with overwhelming power.

For the first time since she started this crusade, doubt crept into Dulla's mind. Is the demon lord really this strong? Has he always been this strong? I heard about what the former demon lord did to the undead, but that happened when the former demon lord was already an experienced demon lord. This boy is too young. He isn't even up to thirty years and yet... He is this strong?

Dulla shook her head and steeled her heart as she stood to her feet. She watched as more than one hundred men were slaughtered in front of her as Floid used his [Advanced Sword Arts] and the rest of her army started to step back out of fear for their lives. They all realized as one that this isn't a battle they can win. The number of bodies that Floid was now standing on was enough to make a small mountain under him and the entire valley was flowing red with blood. Every step the army took would make a squelching sound on the ground because of the amount of blood that was already soaked into the ground. This wasn't a fight. It was a one-sided massacre. A single man was killing them all.

"Wait!!!"

The army all stopped as Dulla shouted this. There were only five hundred men left alive and they all moved to the side as Dulla stood opposite Floid. Dulla now knew that she messed up. She was too rash when she challenged the demon lord. Dulla squeezed her palm in anger. Kronos warned her against this. He said that the demon lord is too strong for her to handle and he was right. Kronos told her not to rush into this. Dulla thought Floid would be weak because he was still a child, but that wasn't true. How can this boy be so strong? How strong will he be once he grows?

Floid was still standing on the hill of bodies and he was looking down at Dulla with bored red eyes. It didn't even look like he had exerted himself at all. He wasn't even breathing heavily. There was blood staining his clothes, and his hair and face had splatters of blood on them as well. He held his sword in a loose grip, but there is no way anyone could take the sword from him because of the red rope that tied itself around his arm. Dulla came forward and stabbed her sword into the ground in front of Floid. She knew that there was no chance here anymore. Even if she managed to get reinforcement, she didn't think there was any chance. The only sort of person that can stop this beast was someone above EPIC-class and Dulla knew that no one above EPIC-class would even listen to her call. She grit her teeth in anger as she bowed her head.

"We surrender,"

Floid stayed silent and he just looked down on Dulla and the other undead as the army followed Dulla's lead and they all started to drop their weapons one after the other. They took a knee in front of Floid and they surrendered.

Dulla hated this. She truly wanted to kill Floid and she wanted to make him suffer as Reginald suffered, but there was nothing she could do here. After watching him kill more than a thousand men singlehandedly, she knew that there is nothing she can do against him. She underestimated him too much.

Dulla spoke up loudly.

"I acted blindly in my anger and I involved other people in the business that was only between the both of us. Since I've come this far, I won't run and I will receive any punishment you give me. But let the other men go,"

Dulla asked for this one small mercy so that the other men would not suffer anymore. Even if she was angry, she was still a soldier and she understood how bad the situation was right now. Losing these many soldiers was bad for the Undead army. Dulla didn't want the army to lose any more soldiers.

Floid was silent as he looked down at them with a cold stare. He could recognize that her request was sincere. She really wanted to spare the other soldiers. But that just made him angry! Is this woman a fool?

"Why should I care about such nonsense? Do you think I will let them go just because they didn't commit any sin? Who decided that,"

Dulla looked up angrily!

"They didn't do anything wrong! I was the one that forced them to fight!"

"And that is their sin. They chose to follow the orders of a foolish commander. This sin is greater than any other that they could have ever committed,"

Dulla grit her teeth in anger as the men around her all paled in dread.
