Just as Lucifer stepped out of his room, he heard the knocks on the door. It seemed like those people were here finally to take him.

He walked over to the door and opened it only to be greeted by Draco. He didn't even bother asking this time since he already knew what Draco was here for. Whenever he came, it was to take him to the higher floors.

"Sir Lucifer, I brought food," Draco replied, breaking Lucifer's perception. Draco stepped aside to reveal a woman standing behind him with a tray.

"You aren't here to take me for training?" Lucifer asked.

"Hahaha, I don't dare take you without feeding you. I made the mistake yesterday, and that once is enough. Even if I took you for training, you'd ask for food there before starting anything, and I'll be scolded for forgetting the second time," Draco replied as he smiled wryly.

"That's true." Lucifer nodded before he walked back to the bed.

The girls placed the tray before Lucifer and left, leaving Draco behind, who waited for Lucifer to finish eating.

Even though the Level Five members were waiting for Lucifer, he still ate while taking his full time. He didn't seem to be in any hurry.

After what seemed like an eternity, Lucifer finally finished eating before he stood up.

"Shall we leave now?" Draco asked patiently.

"Yeah."

...

Lucifer and Draco left the room and went up through the lift; however, unlike before, the two went to a different floor. It was a floor that Lucifer had never stepped foot on.

The floor had nothing except the four walls far away from each other.

There were no rooms on this floor. As for the floor, it seemed to be heavily reinforced, whereas the walls seemed exactly like the walls that were in the Training Rooms that Lucifer had already seen previously.

"Lucifer Azarel, welcome."

Kellian approached Lucifer as he greeted him.

Lucifer wondered why he was alone. Where was Yaliza? He looked around, but he couldn't find Yaliza anywhere.

"Are you looking for Yaliza? He isn't here. We'll be taking turns training you so as to not be overwhelming. Today is my turn. Tomorrow, he would be here," Kellian said, realizing what Lucifer was trying to find.

"Come, let's start your training," he said to Lucifer before he glanced at Draco. "You can leave. Come back after four hours with lunch for Lucifer."

"Yes, Sir." Draco turned back and left.

...

"So Lucifer, let me start. What do you think is most important for a Warlock?" Kellian asked Lucifer when only the two of them were present in such a massive hall.

"Strength," Lucifer answered.

"Wrong," Kellian said, shaking his head. "Strength is important, but it's not the most important. Many strong warriors have perished in the hands of weak ones throughout the years."

"Brain?" Lucifer asked, curious. He was attempting to say what Caen had said. That schemes were important for a Variant?'

"No. We all have brains, actually. But not a bad try. We do need to use our brains a few times to be successful, but that isn't the answer either. So no," Kellian answered.

"I don't know then," Lucifer answered. He had already said what he could think.

"The most important thing for a Warlock is his control of his strength. A loose warlock can destroy even himself in the process if he doesn't know how to control his strength," Kellian answered.

"That's why, today, you'll train your control," he added.

"My control?" Lucifer asked as he glanced at his hands. "Can I control my Decay and stop it from making my life difficult?"

"Decay is a bit different. I don't know much about it, but I doubt you can completely stop it. You can decrease or increase its intensity if you have control, but you can't stop it from working," Kellian answered.

"I'm sure you used Decay many times. But you must have seen it yourself. Sometimes things decayed faster while other times the same thing decayed slower, right?" He asked.

Lucifer nodded in response. He had seen that plenty of times, and he was also curious about this.

"That's because of your control. Since you can't control it, you can't control its intensity. Its intensity is working depending on your subconscious and your mood."

"That's why these things happen. There's one more factor, though. The life energy inside the objects which contribute to how fast or slow they decay."

"You can't control the life energy inside the objects, but you can control the intensity of your decay to help you," Kellian said. "Anyway, that's for later. Today, I'll focus entirely on your strength."

"Come with me," he told Lucifer as he walked towards the wall.

Stopping before the walls, Kellian turned back as he glanced at Lucifer.

"I'm sure you've seen this wall before, right? It's much harder than normal walls, and up to some extent, it can decrease the intensity of attacks to keep itself safe."

Lucifer once again nodded.

"Even though this wall is strong, it can't do anything against your S-Rank strength, but it's a perfect test to help you control your strength," Kellian said before he brought out his Sword.

"Two inches," he said to Lucifer before he made a slash with his sword towards the wall.

As the sword moved, it left a scar behind on the wall that seemed pretty deep.

Kellian kept his sword back before he said to Lucifer. "You see that mark? It's actually two inches deep. That's my control. I could have made the mark deeper or smaller, but I knew exactly how much strength I needed and how much control I needed to achieve this feat. That's what I want from you."

"I want you to use your strength to punch the wall and leave a two-inch deep mark on the wall. Exactly two inches! Not an inch more or an inch less. Can you do it?" He asked. "If you do this, you'd have taken a step forward in controlling your strength to a great level."

Lucifer observed the wall and the deep mark made by the sword before he looked at his fist.

He knew he could use his super strength to leave a mark on the wall. He could even destroy it, but could he control it to that precision? He doubted he could, but he still nodded.

This was good. He needed control, and if this could help him, it was good.

He was able to control his strength up to some extent as he needed, but if he received this kind of precision, things were going to be easy.

"That's good. Get to it then. You have four hours and this entire place. I don't care how many times you try, but I want that exact depth of damage," Kellian said to Lucifer before he stepped back.
