Invicinble Colorless Butler

While Kalya and the girls were enjoying their dinner, Ziel sat in his room and carefully dismantled the cube. It was an artifact he would use for the girls' training tomorrow.

Even though Ziel was focused on his work, he could still hear Kalya's and others' chatter because he didn't cover his room with a barrier. After the final inspection, Ziel heaved a sigh of relief and stored the artifact in the space storage.

"Haa... Today's training went well, and I hope it will continue like that in the future." Ziel leaned his back on the chair and closed his eyes. He had to admit that today's training results were beyond his expectations.

The girls, except for Azalia and Lilith, had a breakthrough to a higher level. Of course, the first two people also experienced a drastic increase in strength. But they were already at the true god level, and it would be difficult to notice unless they broke through to the primeval god stage.

Ziel hoped that the second stage of training could also make their strength skyrocket and greatly help them in future battles. He opened his eyes because he no longer heard the girls' chatter from the living room.

He thought they had returned to their respective rooms to rest and optimize their condition for tomorrow's training. But Ziel suddenly heard a knock on the door as he got up from his chair and was about to lie on his bed.

Knock! Knock! Knock!

"Who?" Ziel asked.

"It's me." Azalia quickly replied from behind the door.

Ziel opened the door and saw Azalia in a transparent black nightgown, which made her look erotic. She is not alone because Kalya is with her wearing a white negligee. Ziel had to admit that Kalya and Azalia were the prettiest among the girls in the cottage, and their current appearance was very seductive.

"Come in." Ziel invited the two to enter his room.

Clara and the other girls would be shy when faced with such a situation. But Azalia and Kalya boldly entered Ziel's room with flirtatious smiles and deliberately stimulated Ziel with their sexy gestures and sweet scent that could drive any man crazy.

"So, what do you want? Shouldn't you guys sleep early and rest your bodies for tomorrow's training?" Ziel asked. He sat on his bed and looked at Kalya and Azalia. Ziel did not invite the two to sit down, knowing that their purpose in coming to his room was not to chat with him.

"Are we not allowed to come to your room at night? I am your fiancé, and we will be your future wife. So it's only natural that we accompany you to sleep." Kalya replied, blushing.

"Yes, this has been agreed by Helena and the others. So there will be no problem with them." Azalia added.

"I never said I would not allow you to sleep with me. I want you to rest early to be fresher when you wake up tomorrow. Then, what do you mean by it has obtained the approval of the others?" Ziel looked at Azalia and didn't understand the meaning of her words.

"During our dinner, Clara kept repeating her questions to Freya and Aishia. Then she suddenly pulled Cordelia, Irene, Kyouka, and Iris to pressure the two girls to answer. Clara wants to help Cordelia and the other three girls learn from Aishia and Freya's experiences." Kalya explains at Azalia's place.

"What do they want to learn from it? What does that have to do with you and Aze coming to my room?" Ziel massaged his forehead after he heard Kalya's words.

"Of course, it has something to do with it. Helena helped Freya and Aishia explain to Clara and asked two of the four girls to come to your room tonight, but neither dared to do that. Clara and Lilith wanted to take their place, but Queen Helena stopped them because it was unfair to the others. Then Helena suggested that the one who could come to your room tonight was the winner of today's training, and they agreed." Azalia finished her sentence.

"I understand. If you guys have decided on that, I won't mind. If so, how long are you going to stand there? Don't you want to sleep with me tonight?" Ziel smiled and patted his bed several times to invite them.

Kalya and Azalia nodded and smiled sweetly when they got Ziel's approval. They slept on the bed with Azalia on Ziel's right and Kalya on the other side. Each of them deliberately pressed their plump breasts against him.

"You guys will only accompany me to sleep and not do anything else, right?" Ziel teased them.

"Hmm… that might depend on the circumstances. Isn't that right, Aze?" Kalya said shyly and threw the question to Azalia.

"Yes. Isn't that also part of accompanying you to sleep?" Azalia replied in a barely audible voice.

"Then what do you want to do?" Ziel whispered and squeezed the two girls' breasts gently.

"Ahnnn..."

"Hnnn..."

Azalia and Kalya let out an erotic moan at the same time. They were caught off guard by the sudden pleasure from Ziel's touch.

"That's up to you." Azalia said and looked at Ziel with moist eyes.

"We will follow whatever you want, Ziel." Kalya spoke in a seductive voice.

"If that is your request, then I will grant it. Don't blame me if you guys can't sleep till morning." Ziel hugged the two girls and gave them passionate kisses. After that, their night activities began, and their moans filled the room until the three were satisfied to share their love and enjoy each other's bodies.

The next day, the girls had gathered at their training ground yesterday, but Ziel still hadn't come because there was something he was doing. Princess Irene and the others didn't know what training they would be doing today, but they were looking forward to it because they wanted to get stronger as soon as possible. Ziel only said that today's second stage of training wouldn't be as challenging as the first stage. While they were chatting, Ziel suddenly appeared with a cube in his hand.

The girls were confused when they saw the cube, while Kalya and Azalia blushed as they recalled what they had done with Ziel all night.

At first, they just wanted to accompany him to sleep. But they didn't expect their desire to be so stimulated when sleeping beside Ziel, and they became so aroused when he touched their intimate parts. After that, they did it very fiercely and looked like an animal. Fortunately, both had great vitality and could accompany Ziel until morning.

On the other hand, Ziel obtained fragments of his memory as the origin god every time he had sex with Azalia. He might remember his past someday if he continued to do that with her.

"What will we do in the second stage of training?" Princess Cordelia asked.

"Before I answer that question, I will explain about energy sources to you. As you already know, there are many kinds of energy sources. The most commonly used by the natives of the Clorius continent were mana and aura, while the elves used spirit power to fight. In addition, there is also divine power which is the exclusive energy source of the divine race." Ziel explained.

Kalya and the others nodded as they already knew that. The girls were silent and waited for Ziel's following words because they knew the explanation was not over.

"You must also know that each energy source has its characteristics, but that's not what I want to explain this time. I want to tell you about the energy source's level. The weakest are mana and aura, and the strongest is divine power, while spirit power is in the middle." Ziel stopped his words and looked at them.

The girls' expressions were severe, and their eyes focused on him. Neither of them interrupted his words before he finished explaining. Ziel smiled and opened his mouth again.

"When you fire the same attack with different energy sources, the damage will also be different. After hearing my explanation, you must know which is weaker and which is stronger. The primeval gods, who will be your opponents in the future, use a source of energy called primordial power, which is much stronger than divine power. So you can imagine how hard it would be to fight them." Ziel ended his explanation.

Even though Ziel hadn't regained his memories as the origin god, he got that information from the Chaos Titan that had been fully assimilated into him. He had learned a lot of essential things about primeval gods that he didn't know and might be helpful in their future battles.

"Then what should we do, Ziel?" The girls, except for Azalia, panicked after hearing Ziel's words. They would lose heavily in that battle if they used their energy source against the primeval gods.

On the other hand, Azalia already knew how terrifying the primeval gods were because she had faced them. She clenched her fists tightly as she recalled her helplessness and the tragic incident in the past.

"Of course, you will use the same energy source as them or even stronger." Ziel looked at the girls and smiled mysteriously.

Princess Aishia and the others frowned upon hearing his words and looked worried about something.

"You can still use your special abilities even if the energy source changes." Ziel added. He knew what they thought when he saw their expressions. The girls let out a sigh of relief after hearing Ziel's explanation. But then another problem came to their mind.

"How do we change energy sources? Isn't that something you are born with? I know that we can use other energy sources. But that would take years to learn, wouldn't it?" Kalya and the girls were confused by Ziel's sentence. But they were sure that Ziel wouldn't carelessly talk about it for no reason.

The source of energy is the power possessed by every creature since they were born. If they practice using their innate energy source, their progress will be much faster and easier than studying other energy sources. But it is possible if one trains hard—for example, Princess Cordelia can use aura, and Kalya learns mana.

"I can change your energy source by using this artifact." Ziel threw the cube in his hand into the sky, and it spun around while releasing a blinding light. Not long after that, the shape of the cube changed into an undecagonal prism.

"This is..." the girls looked at the undecagonal prism in amazement.

"We will start this second stage of training. Please sit cross-legged in a circle with the undecagonal prism in the middle of you. After that, focus on the artifact. Release your source of energy and leave the rest to me. I will help you change your energy source." Ziel gave instructions to them.

The girls nodded and quickly did as Ziel had said. They formed a circle and sat cross-legged with the undecagonal prism in the middle. After that, they released their aura, mana, spirit, and divine power.

"Focus on releasing your energy source. Keep doing it until there is nothing left in your body. I will help you change that energy source with the help of that artifact." Ziel said seriously. He released his origin power and channeled it to the top of the undecagonal prism.

The artifact swirled in the air and sucked in the energy source of the eleven girls. Each of their powers entered each side of the prism. Then Ziel's origin power flowed from the underside of the prism and was injected into the girls' bodies.

"Aaaaaaahhhhhhhh!" Kalya and the others roared in pain as a foreign power suddenly entered their bodies. Their faces were distorted, and the process seemed to be extremely painful from their screams.

The girls felt like a million needles were stabbing them. Not only on the outside, but they also feel pain in their internal organs. Some almost lost consciousness when Ziel infused origin power into their bodies. Fortunately, they maintained their consciousness thanks to their determination and willpower.

"I did say that this second stage of training isn't as hard as the previous one, but that doesn't mean the pain you feel is less than the first stage." Ziel said calmly and increased the intensity of the origin power he injected into the girls' bodies.

"Aaaaaaaaaaaaaaaaahhhhhhhhhhhh!"
