The Fallen Hero Reincarnates as the Demon King's Son-Chapter 2 - 1 - Demon System

'There really is nothing I can do about this... not right now, at least.'

Caliste could only shake his head.

For the last three weeks, ever since he was revealed to have a corrupted mana circuit, he had been working his absolute hardest to fix the situation. However, with the resources he currently had, nothing could be done.

Still, he had learned very interesting things over those past weeks.

The first thing he quickly grasped was the amount of time that had passed since his death.

It had been at least 100 years since he had died. He learned of it by spying on one of the history books his sister, Aleia, had been reading.

That explained a lot of things. For one, the fact that the Demon King's castle was completely intact and peaceful. The overall easygoing behavior from everyone was also something that Caliste had noticed, something he found quite strange.

But now, everything made sense.

The war was over.

As for how it finished, Caliste was still in the dark.

There was one thing that had been on his own. What had happened to the ones he had previously called his friend? Were they still alive? If so, what were they now doing?

Those questions were the reason why, for the past three weeks, Caliste had tried his best to sneak out of his room at night and go into the library.

But every time he tried to do so, his mother was there to bring him back to bed.

It was honestly scary; the moment Caliste even tried to leave, she would wake up.

'Ah... having this small of a body is annoying. I can't even walk yet.'

And there was still something that Caliste had yet to receive. The heavens had told him that he would receive help from them to make him grow faster than his peers, but as far as he had seen, nothing had been sent to help him.

'Scammers...'

Nevertheless, as night fell, Caliste made his way toward the library. He managed to make it out of his room this time, which was almost a first since it had only happened two times in three weeks.

'Maybe tonight will be the night...'

But then, just as he was about to reach the library's door, he felt tender hands lifting him up.

"Tsk, you little prankster. Come into your mother's arms."

Ava hugged Caliste as usual; however, she noticed him making all kinds of baby noises. She thought that he wanted something.

"Hm... is my baby hungry?"

Without wasting any time, Ava removed a part of her nightgown, revealing one of her breasts, and began breastfeeding Caliste, who couldn't complain.

Getting fed was probably his favorite moment of the day.

'Hm... this is the best!'

[You have finally drank enough breast milk to unlock the heavens' helper.]

[You have unlocked access to The Demon System.]

[The Demon System is divided into 8 stages.]

[Activating the first stage...]

'Finally, about damn time.'

[Activation complete.]

[The first stage has been unlocked.]

[The first stage is now activated.]

[Unlocking the Baby Demon System.]

[This system makes it possible to carry out simple life activities such as breastfeeding, eating, physical exercise, and more while converting those activities into experience to gain attributes, skills, and many more.]

Caliste frowned slightly.

'This system...' He couldn't believe it. 'It's completely overpowered! I—I can become stronger by breastfeeding? Eating? Just by living? Finally! The heavens aren't scamming me!'

If what was written was actually true, then it meant he could just enjoy his life and also become strong at the same time.

This was exactly what he needed.

[To reach the next stage, you will have to reach level 20.]

[Current level: 1]

[Experience needed to level up: 100]

Caliste wasn't too sure how hard it would be to reach level 20. But he finally had a goal to reach; still, to reach that goal, he would have to fix his corrupted mana circuit—an element that could be detrimental to his growth.

"Is everything okay, Caliste? Are you not hungry anymore?" Ava asked as she watched her baby's empty gaze.

However, as Caliste heard those words, he immediately woke up. It was time to test out this new system of his.

He closed his eyes and began sucking Ava's breasts like never before. Her perky pink nipples were hard to resist, and now that he had an incentive, there was nothing that could break them apart!

He would suck them until he milked them dry!

Within seconds, a warm, delicious liquid made its way into his mouth, flowing directly into his throat and filling him with energy he had never felt before.

It felt so good and so peaceful.

[Congratulations! You have obtained 1 EXP! You have obtained +1 Vitality!]

A few more seconds passed, and the same messages entered Caliste's mind.

"Hehe! You certainly were hungry, weren't you?"

Ava smiled, happy to see that Caliste seemed to enjoy being so close to her. She wanted him to have the best possible life for as long as possible. She knew of the pressure he would have on his shoulders once he grew up, so she at least wanted to give him the best possible time.

While Ava was having pure thoughts, Caliste... wasn't.

'Mhm, those breasts. They're perfect! I love them!'

His hands moved on their own as he touched them with his small hands.

The sensation was amazing. They felt soft yet firm. It was a sensation that Caliste had never felt in his past life. After all, he had dedicated his entire life to becoming stronger; he had never given a second thought to women.

He simply never had the time.

But now that he had discovered just how beautiful women were, he would never let them go out of his sight ever again!

Then, after a few minutes, fatigue took over Caliste's body as he closed his eyes on his own, his small head falling onto his mother's chest.

Ava smiled and began caressing the top of her child's head, enjoying those moments like never before.

'I hope you stay pure forever. Don't become like your brother...'

In this short breastfeeding session, Caliste had already earned over 10 Vitality Attributes and 20 EXP.
