Worldly Overlord

"It seems like I underestimated your ability, boy."

Josh pressed his hand against his broken nose and wiped off the blood trickling from it, his face turned completely serious.

"This is going to be fun."

Devon took a step forward leisurely as he pointed his finger at him, giving him the come over here sign.

A frown appeared on Josh's face, but he said nothing else, he raised the Katana and shot towards Devon's abdomen. To Devon the attack was very slow, he spun to the left side letting it pass by, and grabbed the handle of the Katana with his right hand while throwing another full-force punch straight at Josh's nose.

Cosmic energy burst out from the Katana and curled around it while also repelling Devon's right hand, unlike the first time, Josh saw this punch coming and crouched to evade the blow.

Josh readjusted his position again and waved the Katana towards Devon's abdomen again.

But this time he got lucky and tore through Devon's abdomen, only to realize that what he had struck was nothing more than a mirage. The original Devon had already reappeared behind with a kick towards his skull.

*Gbam* Gbam* Gbam*

This time Josh didn't avoid the blow, he faced it directly blow with blow. The fight continued for a long period with no one taking advantage of the battle.

"Ding..... Contractor weapon is ready!"

Devon's lips curled into a bone-chilling smile as he looked at Josh, who was 5 meters away from him and was becoming thinner by each minute.

A sword appeared in Devon's hand, it was a Celtic long sword, a large straight-bladed double-edged sword. It was around three feet in length, the hilt had a very small guard, a single-handed grip, and two backward-curving quillons near the pommel.

"Okay, Okay, Playtime is over."

Devon took a step forward and disappeared right after, in the blink of an eye he appeared right behind Josh and waved his sword directly at his arm, cutting it off.

Arrgghhhh!

Though the Demon Slayer Katana had taken over Josh's body, it was still in the body of a human, meaning it could feel pain.

He flew 50 meters away from Devon, but that didn't help at all cause Devon kept on disappearing and appearing beside him attacking him with a sword, punch, kick at one point Devon even delivered a knee blow to him

"You, piece of shit, face me head-on like a man and stop attacking like a pussy!"

Josh roared, his whole body was trembling. There were numerous cuts on the cloth he was wearing and injuries covered his body.

"Alright."

This time Devon appeared in front of Josh, he looked him in the eye grabbed him by the neck with his right hand, and lifted him. Unlike the other time when he didn't know what he was doing, this time he did as he absorbed what remained in Josh's body.

Both the energy and the life source remained in his body.

The Demon Slayer Katana was always the one that delivered torture to both Humans and Demons, but this time it met its match.

The Katana dropped to the ground as nothing remained of Josh's body, not even his bones, as everything was absorbed by the person in front of him.

Devon sat on the ground abruptly, as what he did was hard to digest even for him. He had seen people dying, but it wasn't this way.

Seeing the atmosphere was tense, the voice decided to help out.

"Main Task Completed- Kill Josh Allen(Level 10) of the outer compound.

Reward- Ability to Absorb Celestial Energy and Body Regeneration.

Body regeneration: It grants the contractor fast healing and body regeneration. The speed is based on the contractor level.

Hidden Task completed- Defeat the Demon Slayer Katana and Obtain it.

Reward- Contractor level increased to Level 5.

Right after the message, Devon could feel warm energy passing through his body into every one of his organs, bones, and muscles. The feeling was close to being as good as the one he got from absorbing a human being.

"Ohhhhhh yeah, that's what I'm talking about, it feels so good!"

The Celestial energy was the energy of life in the underground world, it was what the humans called oxygen in the Mortal World. But unlike oxygen, celestial energy could extend one's lifespan by thousands of years, if not millions.

Oxygen was for the Mortal World, Celestial Energy was for the Underground World, and Cosmic energy was meant for the Demons World.

Seeing Devon's overjoyed face, the voice decided to crush it.

"The only reason contractor won that battle was because the other party body was almost drained out completely. There wasn't much the Demon slayer katana could absorb, which made it develop weakness all over."

"If the contractor was as strong as he believes he is, then the contractor could have ended that battle within minutes, so anything less than that is just pathetic."

"... Also, contractor fights like a baby."

All of Devon's excitement died in a heartbeat, he clenched his fist hard. He knew the Voice was right around this time around, so he didn't counterattack back. A Devil shouldn't be excited over little things.

Knowingly, he thought of himself as a Devil.

"Voice show me my stats."

"So, what's the next task going to be about."

"Contractor will find out tomorrow."

Devon cracked his knuckles, he returned to his original appearance and went home but this time he didn't go to sleep or to eat, he went to his backyard and began his training. Which was organized by the Voice.

That night, the world didn't know, but a Devil was born.
