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

The more times that Floid uses his mana core, the more it would also grow. And the more mana he would be able to absorb at once. No wonder his spells didn't just go straight into the S class when he was using them. Floid knew that his skill was supposed to absorb an unlimited amount of Mana from the surrounding, so why wasn't he just absorbing enough Mana to take any of his skills into the S class or even the SS class? That is because his Mana core wasn't large enough to hold that amount of Mana yet. The reason this particular restriction was placed on the mana core was that if Floid used too much mana before the core was mature enough then the mana core would have cracked or broken and that would be one of the most painful experiences of his life.

But I wonder how much Mana I can hold now? I think my Mana core doubled in size since I last used it.

Dragonnel told Floid that he has to learn how to constantly allow Mana from the atmosphere to enter and exit the core as he breathes to allow the core to grow. That way, he won't be killed no matter how much Mana he takes from the atmosphere next time. Basically, he would have unlimited Mana.

Floid nodded and then Dragonnel told him to sit down so they can start. Dragonnel told Floiid to watch him and try to copy what he was doing. It was just breathing. That was what Floid thought immediately after Dragonnel started. Dragonnel was literally just breathing in and out in equal intervals. But Floid didn't just disregard it! He closed his eyes and he also tried to do what the dragon was doing.

After only two minutes, Floid felt something cold flowing into his body. It was the same feeling he gets just before he uses a skill. Mana was entering his core.

Dragonnel was no longer on the floor. He was standing to one side and watching Floid. He was actually shocked when Floid started to take in mana already! It takes a baby dragon about a full hour before they learn how to take in mana and Floid was already doing it in this short time. His potential is so huge that it's a little scary!

Floid stayed in that position for the whole day and Dragonnel was relaxing while Floid worked. When Floid opened his eyes it was to the sight of Dragonnel sitting on a recliner chair while drinking something that looked like liquid nitrogen. It was releasing cold smoke that made the room temperature very low! This lazy dragon.

Dragonnel didn't know that Floid's eyes were already open. And he gave a large sigh as he relaxed some more. Maybe he should transform into his dragon form and go catch some sheep later? They always taste nice! I haven't eaten anything in so long and now I won't hold back at all! Floid cleared his throat and Dragonnel almost fell off his chair in shock!

"Oh, you're finished, master!"

Dragonnel cleared his throat as he stood up quickly and walked up to Floid. He snapped his finger and the chair and cup disappeared. Floid rose a brow as he immediately recognized a new skill appear in his tab.

[Spatial Magic]. A type of spell that can transport anything you want into a space that only you control. You can bring the material out anytime you want as well. How convenient!

"You were in there for a long time master. I think your mana core should have grown by at least 300% over the last few hours. I would have brought you out earlier, but you just seem so peaceful that -"

"You forgot about me, did you?"

"Haha. You're so cruel, master. I would never forget about you!"

Dragonnel was shocked when Floid suddenly said that he forgot about him and he felt sweat run down the back of his neck. Okay, maybe he forgot! It's not like Floid was doing anything dangerous! It was just breathing! Why should I just keep watching you for five hours while you breathe!?

Floid narrowed his eyes at Dragonnel and the dragon looked to the side with a nervous smile. Floid sighed before he looked down at his tab and he saw that he already made a lot of improvement.

Name: Floid

Lvl: 51

HP: 1050/1050

MP: 35000

Job Class: Demon Lord

Artifacts: Nil

Skills: [Fireball - F] [Earth Lance - D] [Rapid Strike - D] [Greater Hardening - C] [Familiar Summons - A] [Spatial Space - B]

Hax: [Duplicate] [He who is loved by Mana]

Floid already leveled up a lot since he fought in the trials. His Mana was way higher than it used to be and even his HP improved. The skills that Floid saw Rosavellt and Andromeda using were also put into his system. [Familiar Summons] was what it was called. Floid decided he would look at it some other time.

After that was done, Floid thanked Dragonnel for his time and then turned to leave. Dragonnel watched his master going and he couldn't help but smile. The improvements that Floid made in just one day were extraordinary. If anyone has more than thirty thousand Mana points after ten years of practice they will be the envy of the entire world and Floid was able to get that many points in one day. In terms of power in this world, Floid should already be a stable A rank. When compared to where he was supposed to be, it isn't that much at all. But if you consider the fact that he has only been here for a day, it is an absurd speed of growth.

I wonder how far he will go in a month! Or even a year!

.....

Later that day, Floid was sitting in an office and signing some papers. They were payments for the products that Andromeda bought for the farm and Floid has to admit that there were a lot of them! The farm was huge though, so he expected it. Floid would have to find a new way to source more income for the castle. According to Alucard, they have been using the money that the previous king left behind before dying, and none of them knew when it would finish. Floid didn't like such an uncertain source of income so he was already thinking of how to make more money for the castle. Floid hummed. Maybe the mana crystals?

Knock! Knock! Knock!

There was a knock on the door and Floid didn't bother looking up as he told Alucard to open the door. Rosavellt entered and bowed to Floid as she spoke up.

"Master. We have gotten news that there is an attack at the village of Hampshire by a small army of demons,"

Floid finally looked up from the papers and regarded her. Hampshire? Isn't that the town that his system told him to save? So the quest is about to start? Floid dropped the paper and asked Rosavellt to explain more.

Rosavellt told Floid that Hampshire was once a demon village, but the hero defeated all the demons there and it is now a village occupied by humans. The village was the closest one to the demon castle. So it is very important to the demons!

Lately, there have been a lot of talks that a small army of demons were gathering to try and take back the village. They also said that it was being led by the former right hand of the fake demon queen. The succubus, Lilith.

Once she finished telling Floid all about it, Floid stood up and grabbed his coat from the back of his chair. How can a demon attack be happening without the permission of the demon lord? At least if you're going to do something that much fun then invite your leader.

"Rosavellt, Alucard. Let's go. It's about time I announced my presence to the rest of the world, don't you think?"

The joy that filled Rosavellt at that sentence was shown obviously on her face! Yes! The demon lord should not be an unknown person! It is time to announce his presence to everyone! I wonder what weapons I should bring with me. As his maid, I can't possibly be lacking on the battlefield. Oh yes, I definitely have to take the battle shield to protect my Lord and maybe also the sword of infinite destruction!? Rosavellt almost shivered in pleasure! She was completely stoic on the outside but on the inside, she was too excited!!

.....

The town of Hampshire was located close to the demon castle. The population was just under two thousand people and it was considered one of the most important towns in the human kingdom. Ever since this town was saved from the clutches of the demons, the number of adventurers here has grown to an absurd number! Since this village is close to the demon castle, it is easy to find demons and monsters that they can hunt for money! This town is an adventurer town!
