A Demon King Through The Worlds

But contrary to what Gyu imagined, the demons stopped the chase and the shooting, just standing in place.

Tap tap tap.

Faint sounds of footsteps could be heard, and then a figure gradually became visible.

The crimson armor on his body still had traces of soot from the explosion he had experienced.

His hair swayed slightly and his crimson eyes coldly scanned those present, his imposing posture shocking the demon slayers, who could feel this man's power even if they hadn't seen him act.

Even though this could have been a chance for them to flee, considering that the demons had ceased their movements, they didn't, their minds were simply paralyzed, they were unable to think about fleeing.

Lucian stopped his gaze on Gyu, before turning to his soldiers.

"Chase them!" He ordered, while stopping in front of Gyu.

The demons returned to chasing and shooting at the demon slayers, while they quickly came to their senses and fled, leaving only Lucian and Gyu, alone in the large, partially destroyed space.

"Who are you and what do you want?" Gyu asked, looking closely at Lucian with his sword in hand, 'Is it one of the kizuki?'

 But in any case, he didn't know why the enemy specifically came after him.

"I am Lucian, the demon king. Naturally, I am here to fight you." Lucian introduced himself in a courteous manner.

"Demon King?!" Gyu's pupils shrank upon hearing these words, he knew that no demon would dare to pose as a demon king.

Then his grip on the sword tightened, his fingers turning white from the force exerted, which showed his nervousness.

"Don't be too nervous, how about I make it fairer for you? If you manage to hurt me, all the demons present will retreat" Lucian said smiling.

"How could I believe your words?" Gyu asked, hardly a demon's words would be trustworthy, especially words like these.

Why would the demon king make such a proposal?

"Surely, after all, I always keep my promises." Lucian assured.

"Sigh" Gyu just sighed, he had no better alternative, so he simply accepted this proposal.

With his sword in hand, he quickly closed the distance, delivering a powerful horizontal strike.

Lucian raised his right arm, easily stopping the blow, which was barely able to scratch his tough armor.

"You still need more strength and speed if you want to hurt me." Lucian sneered, lightly glancing at his arm that blocked Gyu's sword.

The reasons why he had made such a proposal were simple, he wanted to test his armor and make Gyu demonstrate all the movements of water breathing.

Applying force to his arm, Gyu was thrown away in a spinning motion.

Stabilizing himself on the ground, Gyu readjusted his posture and used recovery breathing to ease his aching wrists.

'How can he use so much strength in such a simple movement?' He was amazed, this strength surpassed any demon he had faced, even far exceeding kizuki.

'My wrists hurt even though I have dissipated a lot of the strength, I will have to go all out.' His determination was strengthening, and his concentration was heightened to the maximum.

Running, he soon reached Lucian again. Spinning, his sword looked like a mighty dragon, which grew stronger with each turn.

This was the tenth form of water breathing.

Lucian dodged every blow, while using the transparent world to observe Gyu's every muscle, every breath, and even his blood flow.

By observing and memorizing such movements, he intended to replicate Gyu's techniques.

'After finishing here, what else will be missing? I already got the blue spider lily, the old generation demons have already been eliminated... I almost forgot about Tamayo!'

'With her abilities, it's very unlikely that she would have been killed by any of the kizuki, and she could be very useful if she worked for me.'

Lucian thought, while dodging Gyu's attacks, that they were not being able to bring any pressure to him.

'I think if I don't put some more pressure on him, I won't be able to get anything else out' he thought, restraining his urge to yawn.

Then he began to attack, throwing punches from multiple angles, which Gyu blocked with his sword.

Initially with difficulty, but as time passed, it seemed that Gyu became more and more familiar with this technique.

'Finally the eleventh form!'

Then Lucian's punches slowly intensified, becoming faster and harder.

'He uses fluid strikes along with the rotation of his body to build momentum and deliver powerful attacks, and by flowing and rotating with the opponent's strikes he dissipates the power behind those attacks.'

'A really subtle technique, which must be broken by putting force in the right place.' Concluding his analysis, Lucian opened his right hand, forming a hand knife, and then gave a strong vertical blow, breaking the blade of Gyu's sword.

"Water breathing truly is an incredible technique, and the mastery you possess is equally incredible." Lucian praised, even if he hadn't used his full power in this fight, the fact that Gyu had lasted so long was still commendable.

Right after that, he made a quick move, and cut off Gyu's head.

His arm extended and assuming a monstrous form, devoured the body that lay lifeless on the ground.

What Lucian sought was to combine the insights he obtained, along with all of Gyu's experience, thus obtaining all the knowledge of this martial art.

'I will use the principles of these various martial arts to create an even more powerful martial art.'

Combining various aspects of sun breathing and water breathing and creating a technique that fits a demon's body.

After all, not using the body control capacity that demons have would be a huge waste.

'I wonder what the other people's combat situation is like.'

Lucian knew that Kokushibo's victory was guaranteed, and Akaza also had a great chance of winning, Daki and Gyutaro are the ones who would have the greatest difficulty, even though it was 2 against 1.

But what about Kie? You may wonder.

She was riding on the back of Lucian's flying familiar, watching everything from a safe place.
