Reincarnated as the Demon King's Son

After being satisfied with looking at his status screen, Aldred pulled the Mana Ruby Crystal out of his inventory.

It was larger than the size of his hand. Of course, since he was still a ten-year-old. But what use would he have for this crystal?

[Mana Ruby Crystal (Rare) let the user amplify the damage for fire type spell]

'Oh, so with this my fire spells will become stronger?'

[Yes. There are other types of crystals; Sapphire, Diamond, Emerald, Heliodor, Amethyst, Onyx, and Opal. Each crystal can amplify different elements]

'That's interesting.' Aldred looked at the crystal. 'How do I use it?'

[User must absorb the mana from the crystal and use that mana to cast the spell]

Aldred did as instructed. The crystal glowed then red mist entered his body. He could differentiate the different types of mana in his body. One was his limitless mana, while the other was much stronger.

His eyes glanced at a boulder and decided to use it as a target. Raising his index finger, Aldred cast a fire arrow. His finger sparked, and then blazed in flame before three powerful flaming arrows shot towards the boulder with the speed of a bullet. It punctured through the boulder, creating three large holes with burnt marks.

"Wow." Aldred was impressed by the effect. His normal-looking flame arrows turned into something so powerful and fierce. He looked at the crystal again. It reminded him of the marbles that light up The Jovial Harlequin.

"What is that?" Pongo asked, looking at the crystal. He tried to grab it, but Aldred reacted quickly.

"Keep your filthy fish hand away from my crystal."

"Cih." Pongo crossed his arms.

They returned to the real world. One day there was one hour in real life, so when he returned, everyone was still sleeping tight.

Aldred made himself comfortable in Mary's breast. Mary gently hugged him even though she was still sleeping. He gave her cheek a kiss and closed his eyes. Pongo made his way and slept in the middle.

The next day.

Mary woke up and looked at him in shock.

Aldred rubbed his eyes still slightly sleepy. "What's wrong, Mary?"

"Aldred, are you at silver rank already?"

Aldred recalled that he had leveled up to level 30 yesterday. He nodded. "Yes." He sunk onto her breast and slept again. Saliva poured out of his mouth.

Mary couldn't believe her eyes. How did Aldred reach Silver Rank this quick? Only a few weeks had passed, so how was this possible?

She kept the thought to herself and hugged Aldred close to her body. Her hands moved and caressed his head softly. Mary recalled her talk with the fairy. She said that the boy would help her take over the empire. After seeing his progress Mary was convinced.

'The boy will change the empire in the future. I have to protect him at all cost.'

Aldred unconsciously moved his lips and went to her nipple. He sucked in the milk. Mary giggled as she caressed his head. 'No wonder the fairy said she spoiled you too much. You act like a baby. But I think you deserved it because you have a great burden on your shoulder.'

Mary thought of the future when Aldred will topple the emperor. 'I hope that day can come.'

Bartrem came a few hours later, shouting to wake the soldiers and brought them to train. Aldred woke up as well along with Mary. Both of them did not have to train because Mary was a gold rank while Aldred was a magician, so Bartrem did not force them to train.

Aldred wanted to increase his strength and vitality, so he had always trained with the soldiers. But today, Mary looked so beautiful. Her smooth and pink nipples lay bare without cover in front of him. A drop of milk leaked out. Mary looked at him with a smile. Her sky blue eyes were like a world of wonder. Aldred could stare at them for hours and he wouldn't be bored.

Suddenly, he felt a pain in his gum. He felt sleepy, and his eyes gazed at Mary's neck. Aldred immediately pounced on her. His fangs grew and penetrated it.

Mary moaned as she held his head. Her cheeks blushed and her big breast trembled. She wiggled her curvy hips. Aldred's bite tickled her, making her whole body shake uncontrollably. But she did not feel pain. Only pleasure. Thankfully the soldiers had gone out to train. Though she was fine with showing her breast, letting other see her moaning was a different thing.

Aldred kept on sucking her blood, making her moan repeatedly. His hand went on her left breast and squeezed. Milk spewed out.

"Ahh." She hugged Aldred ever tighter.

They kept doing this. Mary felt weak. Her cheeks were still blushing, and she kept moaning throughout. Her life sapped out as her hand weakly released its hold off Aldred's head.

"Aldred?" An angelic voice called.

Aldred turned around with crazed crimson eyes. His mind was blank, and only his instinct made him act. He pounced on the woman that came out of nowhere.

Eve raised an eyebrow as Aldred pounced at her in mid-air. The scene was in slow motion for her. She looked at her boy who had grown mentally strong these past few weeks. Her heart thumped in pain when she recalled how Aldred fell from the sky. Though she knew where Aldred would fall, it still worried her to death.

Eve cried with a smile and embraced her son as he fell onto her chest. Aldred bit onto her neck. It wasn't supposed to be possible, but Eve softened the skin of her neck and let his teeth penetrate it. He sucked in her blood. She transformed her blood type. If her son drank her pure blood, then he would die. Eve closed her eyes and hugged him. She caressed his head like she always used to do.

Dina and Mary flinched.

Mary was shocked. Who was this woman?

Eve smiled at her and transmitted the message through her mind. 'I am his mother. The fairy that you saw that day was my spell. Please be quiet while my son is drinking my blood.'

Mary blinked in confusion but nodded nonetheless.

Aldred felt the sweet taste of the blood and sucked even harder. Eve blushed. Her boy seemed to be the aggressive type. Even though she had lived for millenniums, she still felt embarrassed and aroused. The main reason was that this was the first time she got her neck bit and her blood sucked.

Her cheeks turned even redder as Aldred sucked harder. His hand then moved inside her clothes and pinched her nipple.

Eve closed her eyes and held herself from moaning. Her body trembled. Eventually, she couldn't hold herself and—

"Ahh."
