The degu energy in this world was really meager and thin. While the one in the Secret Realm was 100X richer and denser. This must be the reason why the average monsters there are all stronger, and it's also the cause why the number of degu users was scarce. Fein theorized after analyzing the difference between the world and the Secret Realm one more time.

They walk for a few minutes before they saw Lucius. He stood in front of the door and wore his iconic smile. He first looked at Fein, when he saw her missing hand his eyes turned deep before he shifted his attention to his beautiful daughter. His gaze softened when saw that she doesn't have any scratches on her.

"You must have experienced intense battle in the Monster World. I'm grateful to you as you kept your promise. I would let someone heal your right hand as a return." Lucius said solemnly.

Fein didn't expect Lucius to behave like that.

He really cares for his daughter huh, as expected of a Father...

Fein smiled and says. "No, you don't have to thank me. Your daughter had help me a lot during our journey. If not for her, we won't be able to defeat the one who took my right hand."

Sofia beside him smiled after seeing Fein subtly praise her.

Lucius on the other hand shook, his eyes widen for a second before his expression returned to normal.

"Is that true?" Lucius looked at his daughter deeply.

My daughter just left for a while and she already grew that strong!?Lucius felt a complex feeling in his heart.

Lucius began to examine his daughter more carefully, and he really noticed a difference in her aura and countenance. Seeing his daughter had finally started to grow her confidence, Lucius began to appreciate his future son-in-law more.

"Yes, I just happened to master some peculiar energy." Sofia condensed one ball of destruction energy.

In her right hand a purple energy rest, but the spatial fluctuated greatly, and an ominous aura of destruction spread on the surroundings.

Lucius who had a fine instinct felt danger from the small purple light on her daughter's hand.

"What's going on!?" Beside Lucius, a black phantom appeared as he looked at them with vigilance.

Lucius smiled after seeing his most powerful servant appear. "Don't worry Zukoa, it's my daughter's stuff."

Fein felt a weird feeling of satisfaction after seeing their surprised faces.Zukoa looked at Sofia with surprise, and at the purple ball of energy in her hands. He felt a bit perplexed because he knew that her master's daughter had finally grown stronger than him. Because he felt that he would not end well once he was hit with that small purple ball in her hands.

As expected of the Master's daughter... Zukoa attributed it to his master's greatness.

Seeing that there was no problem, he bowed to his master and greeted Fein and Sofia before he disappeared.

"We will talk about your matter later." Lucius smiled at his daughter.

Sofia smiled and nodded, she felt proud after seeing her father's reaction earlier.

Lucius entered the mansion with Fein and Sofia following him behind.

Fein gave her a teasing smile from time to time, which made Sofia redden in embarrassment.

Sofia leaned closer to him and whispered. "Hey stop..."

Of course, this scene didn't escape Lucius's perception, but he just turned a blind eye.

p 'They have really gotten closer to each other aren't they?'

Fein smirked at her, it's been a while since the last time his teasing have worked, and now he felt satisfied that he had gotten a comeback after she had trolled her. Yes, this how petty he was.

Just like that, the three of them entered what seems to be Lucius' office.

Fein saw the difference between this place and the rest of the mansion. Because this place was simple and minimalistic. Unlike, the grand and luxurious design on the outside.

Lucius sat on a black chair that and looks comfy.

He felt the temperature was significantly lower than the outside, he scanned the surroundings to find if there was an aircon but he instantly remembered that he was in a Medieval era.Lucius took one book on the shelves beside him under the gaze of Sofia and Fein.

Fein looked at the shelves, his eyes shined for a moment before they vanished quickly.

"Do you want to read the books here?" Lucius stared at him with the corner of his lips raised.

"What?" Fein couldn't help but blurt out.

He didn't expect Lucius could sense his intention just like that.

"Don't underestimate me kid, I have already lived long to read the smallest details, even your micro facial expressions won't escape under my gaze." Lucius snorted.

'Damn, he's too observant. As expected of an old shit who lived for hundreds of years, or even thousand?' Fein felt turbulence in his heart.

Fein scratched his head awkwardly after seeing that he got caught red-handed.

"Well, don't worry you can read those books. I admire your thirst for knowledge, few people are like you. And don't worry I already know that you are aware of our race." Lucius looked at him with a meaningful smile. "Even with my long life, I only witnessed a few geniuses like you. The last person who shocked me became the leader of the most dangerous criminal though..."

Lucius' eyes deepened as if he recalled the last kid who left a deep impression on him.

"That kid, he managed to surpass me earlier than I have expected, really a genius."

Fein looked confused. 'What is this old fox talking about? And he already knew that I know that they are a vampire? Is it because I'm with Sofia for months?'

After Fein analyzed his words, a light of understanding flickered on his pupils.

Lucius saw his eyes brighten, and he knew Fein must have guessed who he was talking about.

"Are you perhaps talking about Niki? The leader of the Laughing Phantom?" Fein asked hesitantly.

Hearing his speculation, Lucius nodded his head with satisfaction.

"You've guessed it, you really are smart! No wonder you became popular in the scientific community in just a few years."

"No, I just knew something about that person, after all, he's really eye-catching." Fein chuckled.

"But not as eye-catching as you... You literally surpassed all his previous records. And in a few years, you would become the youngest S-rank degu user." Lucius stared deeply into his eyes.

'Not years... I only need a few months!' Fein thought so, but obviously, he can only keep this inside him.
