Lust Knight (Web Novel)

Lucien knows Amelia is a fantastic swordswoman, so he summoned his katana, to show her that he has a soul weapon just like she does.

But why did he stabbed the katana in the ground? Because he wants to show her that he is limiting himself, but still confident enough to beat her without a weapon.

He knows that Amelia is very powerful, but he wouldn't be able to fight her with a weapon while holding back enough to not harm her. He doesn't want to take any chances of hurting her.

Still, Lucien had hopes of winning, or rather, confidence in his speed. Because it increased even more after he reached the Mortal Realm and absorbed Aylin's Naginata into his soul.

Of course, the difference between Lucien, who is in the first layer of the Mortal Realm, and Amelia, who is in the seventh layer, is still quite significant.

Lucien kissed Lust while she mentally asked him. 'Are you going to use that?'

He replied. 'Yes. I need to show her that my methods are the most effective.'

Lucien was only at the beginning of the Mortal Realm, but there was already a lot he could do. Lust had been teaching him how to use his demonic energy in many different ways, whether to attack, defend himself, or improve his natural capabilities.

Of course, the use of the demonic energy is limited by how much demonic energy a person has, but that's not a problem for Lucien. He generates large amounts of demonic energy from giving pleasure to his women.

"Let's start." Lucien looked at Amelia, smiled, and started running towards her. He left the katana stabbed in the ground, confusing Amelia.

The distance between them was ten meters. Still, Amelia has very high agility and hoped to have plenty of time to react, taking into account the supposed speed of Lucien.

But she was surprised when she realized that his speed was very similar to hers. The fact that he was unarmed caused Amelia to be unsure of what to do.

She just wanted to prove that she was a lot stronger than him, but she didn't want to hurt him. Although Lucien's speed seemed incredible, she could still clearly see his movements, so she tried to trip him.

She crouched down and spun around, trying to use a sweep kick to trip Lucien.

Lucien and Amelia were using approximately eighty percent of their maximum speed, so he could easily dodge the sweep kick.

Then he forced his body to its limit and jumped over Amelia.

Amelia was shocked when Lucien passed over her, avoiding her movement. Of course, she wasn't trying her best, but still, the difference between two warriors focused on physical combat of the Mortal Realm and Zero Realm is vast.

That meant that Lucien had definitely reached the Mortal Realm, proving Envy's guess.

Amelia didn't think twice and forced her body even harder. Her skin started to glow with blue sparks while she quickly turned around to face Lucien and tried to hit him with the hilt of one of her swords.

Because Lucien was already using his body and senses to their limits, he noticed Amelia's movement and tried to grab her arm while he was still in the air, falling towards the ground.

But her speed was higher than his, even if by a small difference, it was still enough for Amelia to be able to hit Lucien's shoulder with the hilt of one of her swords.

Everything seemed to be happening in slow motion for Lucien and Amelia, who forced their bodies and senses to the limit quickly.

As soon as the handle of the sword touched Lucien's body, the blue light that sparkled on Amelia's body ran towards him along with all the force she put in the strike.

Lucien's senses were even more incredible than the speed of his body, so he could clearly see the blue energy flowing from Amelia's body to his through her sword.

The energy spread through his body in a few hundredths of a second and pushed him back.

*Thud*

Lucien heard the sound of the impact before being thrown several meters into the air.

He fell fifty meters from Amelia and rolled on the ground for another ten meters before he managed to regain his balance and stop. Lust returned into his body again.

Although Amelia controlled her energy so that her force spread over Lucien's body, thus avoiding piercing his shoulder with the sword hilt, he still suffered some internal damage.

Lucien spit some blood on the ground as he heard Lust's voice in his mind. 'You knew it would happen.'

'I wanted to test my limit before using that.' He replied.

'Don't hold yourself back.' Lust spoke in a confident tone.

Lucien stood up, stretched his arms and legs to get rid off of the numbness, and looked at Amelia. "You're still as fantastic as always, sis."

Amelia tried to contain her surprised expression. "You have successfully reached the Mortal Realm. Congratulations, brother."

Reaching the Mortal Realm was the least expected of Lucien after making the soul contract with a great demon, even if it was Lust, the supposedly least talented sin.

Still, he did it very quickly, and now, supposedly in the first layer of Mortal Realm, he was almost as swift as Amelia, which surprised her and Envy a lot.

"Take your weapon. I'll not go easy on you." Amelia swirled her swords as the blue energy started to sparkle around her body.

It is a skill that Amelia copied from a Light Empire mage with Envy's ability, copy. She could infuse electric mana in her attacks and improve her speed for a few seconds.

Of course, just like Lucien. Amelia's ability to use Envy's abilities is limited to how much demonic energy she has. Unfortunately copy also has other limits, such as only being able to use the copied ability several times.

Also, she wouldn't be able to use copy on the same ability until she used up all of the copied abilities uses, in addition, the cost of demonic energy rises with each use of the copied abilities till the uses run out.

So, like Lucien, Amelia and their sisters will be improving the great demons prime abilities as they increase the quantity and quality of the demonic energy they possess and produce.

Lucien summoned his red katana again, which like Lust and his demonic energy, couldn't be too far from him.

He again stabbed the katana in the ground while smiling at Amelia. "Okay, I'm not going easy on you either."

Then he started using his new trump card. Like Lust manipulated demonic energy in her body, Lucien began to create a purple haze around him while using his demonic energy to boost his physical capabilities significantly.

Lust explained to Lucien that this way of using demonic energy is very effective, but also very difficult to master and also quickly consumes his demonic energy. So hosts shouldn't really use this ability until they are more powerful.

Still, Lust thought that Lucien could already use this ability, not only because they had a lot of demonic energy but also because he has excellent control over it, possibly because he's half-demon.

And now Lust's theory was being confirmed as the purple haze circled around Lucien, making his clothes and hair sway as if in a strong wind.

His eyes started to change from blue to bright purple as Lucien felt his body grow more powerful than ever. His senses were bein. amplified so much that he can hear something from five miles away.

Of course, Lucien also felt his demonic energy reserves rapidly decrease, so he knew he has less than a minute to make his moves before he is exhausted.

Amelia was a little confused but only thought that the purple fog was a simple ability of Lust until Envy warned her mentally.

'Watch out!! He shouldn't be able to do that yet. He's using demonic energy to get a lot stronger, but it will only last for a while, so try to defend yourself.'

Amelia held her swords firmly while she was on high alert, waiting for Lucien's next move, but nothing prepared her for what came next.

"WH-" She hadn't even blinked, but Lucien disappeared from her vision with the quickest movement she had ever seen, or rather not seen.

Then in less than a second, she noticed a shadow beside her, but before she could make a move, she felt Lucien's hands... touching her ass.

"KYAAAA!!!" Amelia panicked and jumped forward while yelling.

Her soul weapon, the white swords, disappeared along with the electric energy that sparkled around her body and all her concentration.

Amelia was totally of balance and started to fall when she touched the ground with her foot.

But she didn't fall to the ground because of Lucien, again using his super boosted speed. He appeared beside her. Then he held her, making Amelia panic even more.

"YOU IDIOT!! Why are you doing these weird things to me?!?!" She punched Lucien in the chest. Of course, without force, as she was too embarrassed to do anything right.

Lucien helped her to stand as he stopped using his demonic energy, and the purple haze around his body disappeared. "Okay, I'm not doing anything else."

Amelia was still very embarrassed and continued to punch Lucien. "Dammit!! Why did you do that?! You are a pervert!! We are siblings!!!"

Envy rolled her eyes as Lust materialized beside her and laughed at the situation. "I hoped this was going to be a good chance for him to test his limits, but things ended like that..."

"Fuck, Lust! It wasn't fair. He's not supposed to be able to use demonic energy like that, and it was supposed to be a decent fight and not him to bullying his sister." Envy responded

Lust shrugged. "What blame do I have if she is so shy? How could he win the fight without touching her?"

Envy looked seriously at Lust. "Tell me, what did you do? How can you have so much demonic energy?"

Lust pointed at Lucien, who was trying to calm Amelia. "It was all him. He is the most fantastic person I have ever met. He always surprises me, so don't ask me difficult questions, because I can't explain it either."

Envy's eyes sparkled as she gazed at Lucien. She very much wanted to find out his secrets and cooperate with him in every way possible, of course, she was craving for the enormous amount of demonic energy he could produce.

While Lust explained everything that happened to her and Lucien, to Envy. He kept trying to calm Amelia, who was still furious.

"Shit, shit, shit!! What kind of brother does that to his own sister? I'm going to beat you up!!" Amelia continued to punch Lucien, who didn't react.

Lucien did not want to bully Amelia, but when he approached her, he was unable to hit her, and only a simple touch would not prevent her from striking him again, so his only alternative was to attack her shyness.

And well, squeezing her ass worked better than he expected. With that simple action, Amelia lost all her ability to concentrate and fight. But now she kept punching him…

"Calm down, sis... or... I'll do it again." Lucien tried to threaten Amelia, but it didn't work out as he planned.

She started to hit him harder. "Do you dare?!?! Are you really going to continue bullying your sister??!!"

In a quick movement, Lucien pushed Amelia against the carriage and held her arms against the door. "If you don't calm down... yes, I dare do that again."

While Lucien held Amelia's arms, she felt that comfortable warmth that she felt only in his embrace again.

He had his face so close to hers that she could smell his breath. And damn, that fantastic scent was making her body feels weird.

Amelia turned her face to the side while blushing. "Y-you d-don't dare!"

Lucien slowly brought his face even closer to hers. "Are you sure?"

Amelia started to panic again and had to use all her will to gather enough energy to try to kick Lucien.

*Woosh*

He quickly jumped back, dodging her kick. But not without making a last move.

Amelia blushed more than ever. She looked at her left breast, which was a little warmer than usual, and then looked at Lucien with an expression both embarrassed and furious.

"YOUUUUUU!!!! STUPID BROTHER!!!!!"
