Magic System in a Parallel World

After breakfast, Lia requested for Leo to use Mana Drain on her again.

Leo didn't even bother trying to talk her out of it and treated it as though it was part of his daily routine.

Several minutes later, the two of them would lie on the bed to rest until Lia wanted more.

The two of them would continue this routine until lunch, where they took a short break, then they would continue until it was sundown.

Once Lia felt her body heating up, she warned Leo, who would proceed to drink a high-grade energy potion before using Mana Drain on her.

Leo quickly realized how much easier it was to absorb Lia's mana compared to yesterday, most likely because of his increased Mastery Rank with Mana Drain. With that being said, it was not an easy task to constantly use Mana Drain, and he would still be on the verge of passing out by the end of their session.

Furthermore, his Mana Drain Mastery Rank increased to 'C' towards the end.

"How are you feeling?" Leo asked her after their session.

"I'm fine. My bloodlust is under control," she responded in a calm voice.

"Great. Do you mind if I go clean myself?"

"Go ahead."

"Thanks."

Leo exited the room and went to take a hot bath.

Edwin came to check up on them shortly after Leo left.

"D-Did you finally kill that brat?" Edwin trembled in joy when he couldn't see Leo inside the room when he entered.

"No, he's still alive. He's just cleaning himself in the other room." Lia nonchalantly said.

Edwin's eyes widened with shock after hearing her words.

"You allowed him to leave this room by himself?! What if he ran away?!"

Upon realizing this, Edwin rushed out of the room and went to the other room to see if Leo was actually using the bathroom.

Meanwhile, Leo was enjoying the experience of taking a hot bath inside a luxurious bathroom that was the size of a spa, not to mention the bathtub that was also a jacuzzi.

However, his peace would not last long, as Edwin would suddenly barge into the bathroom without warning.

"Hey! Don't you know how to knock?! What if I had been doing some private business here?! Are you trying to kill me with shame?!" Leo exclaimed.

"You didn't run away…?" Edwin muttered in a dazed voice.

"Why would I run away?" Leo frowned.

"Although I may be a sacrifice, I am enjoying life right now. Not only am I being fed first-class food three times a day, but I even get to be with a beautiful girl like the Young Lady all day long. Of course, these bathtubs are also great. It's like a massage chair and a bathtub combined!"

Edwin's eyebrows twitched, and he spoke in a cold voice, "Once again, you're getting way too comfortable. Don't you dare treat this place as though it's your own house! Now get out and return to the Young Lady at once!"

However, Leo remained in the bathtub, and he said, "I would love to leave, but I can't do it with you standing there and watching me like a hawk. Also, I don't understand why I must be with her at all times. Her bloodlust has already been quenched for the day, so we don't have to worry about it until tomorrow."

"You don't need to understand anything. You only need to follow orders and do your job properly!" Edwin growled in a low voice before leaving the bathroom.

Leo got out of the bathtub and returned to Lia's room shortly after, and once again, she was nowhere to be found.

A few minutes later, she would come out of the bathroom with a towel on her head.

Leo quickly turned around and asked, "Are you really cleaning yourself in that red water? Isn't that… unhealthy?"

"The water is clean. The water is red because it's dyed."

"Seriously? What's the point? To make it feel like you're bathing in blood?"

"No, I just like the color red."

"I see… What about the blood? Are they fake—"

"They're real."

"..."

Leo immediately regretted asking her that question.

"Anyways, let's go to sleep. Tomorrow is the last day of your rampage, right?"

She nodded.

Once Leo entered the bed and laid his head on the fluffy white pillow, Lia approached him and rested her head against his chest without asking, almost as though it was a natural thing to do.

"..."

Leo didn't say anything, mostly because this was his last night in this place.

'Just one more day… Endure it…' he convinced himself as he tried to sleep, but the fragrance coming from Lia's body made it a lot harder for him to sleep that night.

The following morning, Leo woke up before Lia and gently moved her head off his chest.

Edwin showed up at the same time with breakfast, and his eyebrows twitched a little when he saw how Lia was still sleeping.

'Two days in a role… Something is wrong here.' Edwin thought to himself, but he couldn't imagine what was happening to Lia.

'If only the Young Lady didn't forbid security cameras inside the room…' he sighed inwardly.

Fortunately for Edwin, Lia woke up shortly after he entered the room, so he didn't have to make breakfast for a second time.

After breakfast, Edwin returned to clean up the mess.

"Young Lady, how are you feeling? You haven't satisfied your bloodlust for two days now. I'm afraid that you might go on a random rampage later." Edwin asked her after cleaning up their breakfast.

"I am fine," she calmly said.

"That's good, but just in case, I have brought another sacrifice for you."

Leo raised his eyebrows after hearing Edwin's words.

"I don't need another sacrifice." Lia spoke with a slight frown on her face.

"If that's your decision, you can get rid of him. However, he's already here, so there's no point in sending him back now. I will send him here in a bit."

Edwin glanced at Leo before leaving the room.

"Are you going to kill him?" Leo asked her once they were alone.

"You can't use Mana Drain if he's here, right? I will give him a swift death." Lia said in a nonchalant voice.

"That old man is doing this so Lia could recall the thrill of shedding blood and hope that she might lose control and kill you as well— probably." Lilith said.

"That is not going to happen. I am not going to let Lia shed blood before me. That old man is going to be disappointed." Leo said with a resolute expression on his face.

"And how are you going to stop her from killing this sacrificial lamb?" shed asked.

Leo suddenly approached Lia and said, "Lia, can you do me a favor and not kill this person?"

Lia tilted her head in a puzzled manner.

"Why?"

"Well… You may like killing, but I actually don't like to see dead people. If I see corpses, I might not be able to use Mana Drain even if we're alone."

"Oh. I see. Then I won't kill him."

'That was easier than I thought…' Leo thought to himself, but he didn't complain.

"Thank you."

Sometime later, somebody knocked on the door.

"Hello, I am Devin, and I am here for the special quest." A young male voice resounded after the knocking.

The door opened the next moment, and a young man who had many semblance to Leo with his dark blonde hair and hazel eyes walked into the room.

Leo was speechless after seeing this new sacrifice.

'That old man is definitely doing this on purpose!' he cried inwardly.

Once the door closed, Lia left the bed and turned to look at Devin, whose eyes widened with shock upon seeing red eyes.

"Y-You?! A vampire?!" Devin subconsciously withdrew his weapon.

Leo felt like facepalming at this moment, but he had to keep an eye on Lia so she doesn't kill him.

Lia narrowed her eyes slightly, seemingly annoyed by Devin's presence.

"You're lucky that I cannot kill you. However, I can still torture you." A cold smile appeared on Lia's doll-like face as she retrieved her black dagger.

Leo swallowed nervously after seeing this, and he said, "Lia… I dislike torturing more than killing…"

Lia's body froze when she heard his words, and she turned to look at him with a profound expression on her face.

"Just endure it for today, okay? I will make it worth your effort." Leo continued.

Lia turned to look at Devin, who was trembling from fear.

"Get lost before I change my mind."

"Thank you!" Devin immediately turned around and ran outside the room.

However, he didn't get very far, as Edwin was waiting in the hallways.

When Devin saw Edwin, he stopped and shouted in a panicked manner, "W-Why is there a vampire here?! What is going—"

Edwin's arm disappeared for a second.

The next moment, Devin's body fell to the ground, his head removed.

After decapitating Devin with his bare hands, Edwin stared at the corpse with a pondering expression, 'The Young Lady allowed him to run away? No… This wasn't done by the Young Lady! It's that brat! He's the reason she's been acting weirdly recently! He's a bad influence on her! I must remove him before he could defile her any further!'

Edwin's eyes emanated intense killing intent.

Back inside the room, Leo said to Lia with a smile on his face, "Thank you for holding yourself back. As a reward, I will Mana Drain you as much as you want today."

"Okay."

Although her expression remained nonchalant, Leo had a feeling that she was happy.

They entered the bed shortly after and Leo began using Mana Drain on her.
