Lucifer wanted to merge his attacks, planning to increase his strength even more.

He knew that if he could at least merge two of his powers together, starting from the ones that could easily be merged, he could then move over to the harder ones.

That's why he wanted to merge his wind and his lightning when attacking.

Both his skills had different advantages which could certainly complement each other.

His lightning was fast and dominating. It could destroy anything it hit. On the other hand, his wind was swift yet versatile.

Wind attacks could easily be controlled, and their trajectory could be changed mid-way. That wasn't possible for lighting.

Lightning was so dominating that it was impossible to change its direction once the attack was made. Lightning could destroy anything in its path, but it was useless if the attack was dodged.

For a person, it was comparatively easier to dodge the attack of lightning with their quick speed than it was to dodge a wind attack that could chase after them.

On the other hand, it was much harder to dodge the wind attack, but it was much easier for them to protect themselves even without bothering to dodge the attack.

Any decently powerful shield could protect from wind attacks, no matter how versatile they were.

Wind couldn't cut metal either. At least he hadn't been able to make his wind attacks as strong. No barrier could stop the attack of lightning.

Both these skills had their own advantages and disadvantages that made them imperfect. And Lucifer wanted to remove that imperfection.

Moreover, it was only his initial plan. He wanted to start with something more manageable. His actual plan was to merge wind and his decay, if possible.

Unfortunately, that was just a distant plan at the moment. Even he didn't know if he could actually do it or not.

As he practiced, with one hand, he cast his lightning bolts while casting his wind blades with his other hand.

As he targeted the walls, they kept being damaged more and more with each attack.

Each attack created a vibration in the surroundings. The subtle vibrations woke Yaliza from his sleep. He slowly opened his eyes to see Lucifer's back facing him.

Lucifer was attacking the wall in front of him again and again.

Yaliza wondered what Lucifer was doing—attacking at the same time with different powers again and again. He assumed that this guy was practicing.

He stood up and stretched his arms. Even though he didn't make much noise, Lucifer heard the sound of his footsteps in the silence of the Dungeon.

He turned around, noticing Yaliza. "You're up."

"Were you practicing?" Yaliza asked.

"I was trying to test something. So far, no luck," Lucifer replied, walking back. "I wonder when others will wake up. I've already started getting bored."

"I doubt they'll wake anytime soon. If they were to wake up, they would already be up by now." Glancing at Alicia and others, Yaliza shook his head.

"How about we practice then? A battle between the two of us just to remove some boredom? We already have plenty of time?" Lucifer suggested.

"You want to fight me?" Yaliza asked, surprised.

"Yeah. I heard a lot of good things about you, especially related to your speed. Fighting you would only improve me. Let's go through one round?"

"Alright. If that's what you want. But what if the sleeping ones get hurt in our battle?" Yaliza asked.

"We can't go too far for our battle since we need to keep an eye on them. And if we fought close, one of your stray attacks might hit them."

"I won't be using any long-range skills. I'll only use wind for movement. I won't even use my strength. You can also use your speed and your strength. That should be fair. That way, they won't get hurt either," Lucifer replied.

Yaliza nodded as he moved away from the sleeping youngsters.

Lucifer also moved away from them. They were going to fight ten meters away from the ground so as not to hurt them.

"Are you prepared?" Lucifer asked.

"You can start when you feel like it," Yaliza replied.

"On the count of three... One... Two... Three!"

Lucifer's figure flickered as he moved with the wind, appearing in front of Yaliza within the blink of an eye. He attacked with his right hand.

"You're fast. But I'm faster," Yaliza's voice appeared from behind Lucifer.

Lucifer's attack clashed with empty air as Yaliza had already switched places.

Seeing Lucifer's back, Yaliza reached out his hand to grab him by the shoulder to throw him away.

As soon as Yaliza's hands touched Lucifer's shoulders, Lucifer placed his hand over Yaliza's hands, holding them in place.

Using his wind, he swiftly jumped to land behind Yaliza while still holding his hands.

Yaliza found himself in pain as his hand was twisted by Lucifer in a painful manner. He didn't make any noise and instead kicked back.

Lucifer also used his right foot to block the kick of Yaliza before hitting the back of his knees, bringing Yaliza down to his knees.

"Well, that was underwhelming. Yaliza, why were you trying such lame skills on me? Did you really think they'll work?" Lucifer asked, freeing Yaliza's hands. "I didn't even need to use my left hand to bring you down."

"You've gotten good since the time I trained you," Yaliza let out, standing up. He couldn't help but rub his shoulder.

"Yeah. You and Kellian were the ones at that time who taught me about the importance of battle skills that don't depend on powers. I now understand what you meant. Fortunately, I had an opportunity to learn more in this field," Lucifer responded, talking about his time at the academy.

"So you really should take my skills seriously. I'm not just a Warlock but a decent fighter as well," he added as he walked back again.

"Is that so? Let's make it the best of three then. I'll take you more seriously now," Yaliza said, smirking. He cracked his knuckles as he actually decided to have some fun.

"Is that so? You can go first this time." Lucifer nodded as he prepared for a serious battle.

This time, Yaliza attacked first. His speed was much faster than before. It didn't look like he was moving; instead, it seemed like he had simply teleported.

He appeared in front of Lucifer within the blink of an eye and attacked. His attack was pretty ordinary as it seemed no more than a simple punch.

The speed of this punch was much faster though. Strangely enough, Yaliza stopped before his attack could even land on Lucifer's face, while another grin formed on his face.
