Don't worry, brother, your sister will accompany you wherever you go!

Underworld.

Currently, in the temple of Goddess Hecate, Jason is learning magic under the guidance of Hecate.

And Hecate is teaching while sitting in a clearly lazy posture, by leaning halfway on the side of the chair and lying on her side, facing the light emitted by the sword of the God of Light Apollo hanging in the hall.

While showing her beautiful figure of a goddess, due to sitting on her side, her vermilion eyes are observing Jason, who is drawing a magic spell in front of him.

And, every now and then, Hecate is also yawning.

"Teacher Hecate, be more serious..."

Jason helplessly looked at his teacher who in his words is acting like a lazy cat goddess.

Because Jason doesn't know what should he do except for saying directly to her.

'Sometimes she looks like a graceful and noble goddess, but sometimes she becomes lazy and casual.'

'Sometimes she stops caring about everything else, but sometimes she becomes gentle and patient.'

"Serious?... I want to be serious too."

Hecate lazily replied to Jason: "But, my student, you can't blame your teacher for not being able to do it yourself."

"Someday, if you can hold on for a long time, come back to me. "

"Hold on for a long time?... Teacher, can't you just do it slowly?"

Jason said helplessly: "Being so fast, you don't even give me time to adapt, of course, I can't hold on."

"But Medea can do it." Hecate looked at Jason and said, "Even Medea's senior, she's even really good at it too."

"They are my senior... and are geniuses, but I'm not."

Jason explained in a contemptuous tone: "Teacher, you must know that people cannot be generalized."

"Moreover, both of my seniors are different from me, and they are not even human! "

"You are not a human."

Medea, who is wearing a long purple dress and unknown to Jason has been back for a while, just heard Jason speak ill about her, so couldn't help but lightly knock Jason's head with the Magic Staff in her hand.

After all, because Jason is taller than her, she can only use her Monk Staff to tap his head.

Jason turned his head to look at Medea.

A fourteen-year-old beautiful girl, although there is still some immaturity on her face, her overall appearance is already that of a young and elegant princess.

Originally, at this time, Medea should have been a polite, innocent, and lovely young girl.

However, Medea faced circumstances not foreseen by even her teacher.

So, being under the influence of Jason for such a long time, Medea is no longer pure, she has been tainted.

"Teacher, what are you talking about?" Medea asked while walking over, then sat beside Hecate and began combing her hair that are scattered on her shoulders.

"Talking about the progress of this idiot in learning magic." Hecate pinched Medea's face and said: "Completely unlike you, I just have to give you a few tasks then you are able to complete them all on your and even understand everything, and now, you are about to graduate in a few days."

"But he... let alone doing the same, he doesn't even last long."

Hearing this, Jason retorted angrily: "Nonsense, I can obviously endure for long, I haven't slept in three years!"

"Then, do you dare to spend three whole days and three whole nights with me?" Hecate's eyes are slightly slanted as if she is asking with a smile but also not a smile.

"...Cough, Medea, I seem to have run out of the sleepless potion, so, see if you can make some more for your brother."

Seeing Jason, who is seriously changing the subject, Medea giggled.

But Jason is also feeling very helpless about this: 'Spending three whole days and nights together with teacher Hecate?'

'Isn't that just asking to be squeezed dry!'

'How could I have ever guessed that learning magic is comparable to learning advanced mathematics, and the higher the level of a spell, the more things must be calculated.'

'Making potions feels like doing chemical experiments, and learning spells feel like learning mathematics.'

'Damn it!'

'There is definitely something wrong with this world!'

"It's not like magic is too complicated..." Medea commented

"Complicated? Is it really?" Hecate looked at Medea.

Medea tilted her head and replied.

"Is it?... I also don't think so."

"...I can feel deep malice from both of you!"

"It's only maliciousness yet... In these past three years, your younger sister has learned enough to graduate." Hecate sighed: "And I have tempered your soul with unquenchable flames, but you have only reluctantly mastered the basics by now... do you have something to say about this?"

Jason looked up and decided to ignore Hecate.

It is an obvious fact that in the current world, whether it is the gods or most of the heroes, they mainly focus on exercising their bodies, practicing archery, swordsmanship, and other combat skills.

Because in the current era, this is the easiest and most practiced way of turning one's own potential into strength.

This is also the reason why most of the powerful existences, if they are not Gods, then they are demigod heroes; after all, Gods and those with their bloodline really do have powerful bodies with very high potential.

But, Hecate has accepted Jason precisely for the purpose of experimenting with this belief, she wants to experiment that using her magic, is it possible to reach the same height without possessing divine power.

Because it is exactly because of her magic that she is considered so powerful and terrifying.

As for exactly how strong Hecate's magic is...

Just the fact that Hecate has created a spell that can make her easily enter and leave the Underworld at will, something even God-King Zeus is incapable of doing, and she has also created a spell to copy the effect of the Invisibility Helmet of Hades, are enough to show the capabilities of Hecate's magic.

Moreover, these are just two of the high-level spells Hecate has carved on the Magic Staff, that Jason has begged Hecate to make.

In Hecate's case, her most powerful thing is neither her physical strength nor her divine power that has already reached a level comparable to many of the Olympians.

Rather, it is the magic she has been studying until now, and even then her research hasn't stopped.

The power possessed by the gods can actually be regarded as a kind of authority to manipulate a set of laws of the world to their will, which is why the gods of this world can easily perform disaster-level actions.

Like Demeter's action of making the whole land dry up and everything start withering.

However, if Hecate wishes to, although partly, she can also do the same by just using her magic.

Because her attainments in magic have already reached the point where she can partly manipulate the laws of the world that don't even come under her divinity.

Otherwise, Hecate would not have been able to immediately hide the path of God slaying she has observed in Jason by using her divinity, especially from the three Goddesses of Fate.

And as a matter of fact, it is exactly because of this that Hecate has no interest in the rights of gods, nor does she care too much about beliefs.

Simultaneously, it is because of this, that after thinking deeply for a while, she believed that it is not exactly impossible for Jason to create the miracle of killing gods.

Because she has long known, just like Titan Prometheus also knows, that it is not impossible for the Age of Gods to come to an end.

After all, both are aware of the fact that the Age of Gods is continuing only because humans, unconsciously or consciously, don't believe that the Age of Gods can come to an end.

The only thing needed is a big trigger, that she and Prometheus have no idea about.

"Speaking of which...it's been four years." Hecate, who had just dealt a blow to Jason's confidence, said as if she has suddenly remembered something.

"Well, it's been four years for me, teacher." Medea nodded.

"It's been four years...you should go back too." Hecate touched Medea's head, then looked at Jason and said: "And you, it is almost time for you to go out for a walk... Athena and other Gods are impatiently waiting for you."

"Teacher, please, don't tell me about such horrifying facts, okay?"

"It's no use asking me, although horrifying, they are facts."

Looking at Jason, whose face is full of unpleasantness, like always, Hecate is inevitably amused, and couldn't bear teasing while narrowing her eyes and smiling: "Anyway, you have to face them sooner or later... Wasn't it you who has said that knowing a problem you shouldn't sit still and must take the initiative to attack?"

"I really can't sit still just to die because of encountering an unknown accident, but if I know that I will definitely die upon going out, then it is not taking initiative to attack, it is called taking the initiative to die!"

"Look at what you are saying, Athena and other Gods won't eat you."

"No, Hera will."

"It's safe." Hecate waved her hand and said: "Even if Hera wants to, she can't eat you while everyone is watching, at most... she will catch you and lock you up in a small dark room, then... educate you properly; anyway, you just have wait for me, when I think of you someday, I will pick you up."

"After all, your soul is immortal, so unless Zeus allows it, which he will not do at this stage, you won't die."

"...Teacher, let me ask you a question. After we leave, you will start doing your own experiments, right?"

"Um, right." Hecate nodded: "You two little rascals have been pestering me for several years, I have long wanted to especially throw you out."

"For how long will you be doing that experiment?"

"Um...probably for a few days or months?"

"Teacher, I've already asked Sister Persephone, so don't lie to me." Jason gritted his teeth: "The shortest time you have disappeared for is decades! And the longest, according to God Hades is even a century-long!"

"Oh... so what?"

"I won't go out!"

Jason said firmly: "I am definitely not going out!"

"Like it matters to me what you want to do." Hecate looked at Jason in exasperation: "Anyway, I'll throw you out tomorrow, goodbye and have an adventurous journey!"

After speaking this, before Jason could say anything, with a soft bang, Hecate's body scattered into ghost butterflies and disappeared.

"It's over..."

The expression on Jason's face became desperate, showing that everything he loves has been lost.

"That... brother Jason, don't worry too much."

Finally, Medea couldn't bear it and said to Jason: "If you are really captured, I will definitely find you and accompany you, you can rest assured!"

Jason looked at Medea who is trying to assure him with a serious face.

But, Jason didn't feel reassured at all, rather, he even had an urge to cry.
