"Hehe… you seem unusually optimistic today." Immortika wrote instead of answering what Jacob asked it.
Jacob frowned, "Do I sound optimistic to you? I'm not in the mood to play your riddle games."
"Come on~ if you act like this, where is the fun in that? You only have one life, and being so cold all the time is greatly harmful to your mental health. I like it when you're going all psychopath, letting your true nature out…hahahaha!"
Jacob didn't find this funny and stiffly replied, "It appeared I've summoned you nothing."
"Heh, alright you, heartless man, I'll bow to your wishes this time since I can. The Mystic Signature information you acquired from your new friend is accurate but limited.
"First, if you want to etch the Mystic Signature onto a magic core, you need to discover the Mystic Signature from within. Now, this is the trickiest part; to find a Mystic Signature, you need to have an innate ability called Inner Espy, or you need to find a magic scripture to learn the limited version of it or something that works like it.
"Only then will you be able to see your magic orbits, magic core, or anything supernatural that can't be seen with the naked eye, and then you can discover the Mystic Signature. But only if it is fully formed, not if it's in a disarray state.
"However, the next step, etching, it can be done in a curd way, like carving your magic core with the help of another extremely rare innate sorcery ability, Matter Manipulation. Anything besides it, even its imitation, won't work, and you will be dead before you know it.
"Then there is a gentler and safer method, and you won't even need to do anything that is directly achieved the Unique Magic Core Rank, and as long as your Mystic Signature is not in disarrayed state, it will innately be etched onto your magic core and manifest!
"The last thing you are confused about is why that Demi High Orc had a Mystic Signature despite being only an extraordinary rank. It's even more simple, you see, a descendant of a legendary rank had a massive advantage over those who have no destiny with such a being.
"That is, as long as they can form their Mystic Signature, it will automatically be etched onto their magic core without them needing to do anything at all!
"Is this infuriating? Hahahaaha… the commoners have to work their ass=off, and even then, they will not escape their miserable fates, while nobles will just have to eat and grow, and they will get everything!
"The same rules apply here, Legends will remain, but those who made them Legends will forever be forgotten… hahahahahah…
"Oh, your theory about the etched Mystic Signature vanishing from the magic core once the bearing died is absolutely accurate. Well done, I guess…hehehehe…"
Jacob wore an astonished expression at this moment because, just as Immortika stated, this was indeed infuriating. Although his doubts were cleared, he learned even more mysterious things about those strange innate abilities and how the magic scriptures seemed to be a copy of them.
Jacob knew he should dread the day when he met with such an existence, or he might already have in the face of Captain Free Sword and his crew. The Unique Rank was called unique for a reason, and now that he had learned the truth about the Mystic Signature, he felt even more dreaded by the unknown Legendary Rank.
Nevertheless, he knew there was no point in thinking about something which was simply too far away from him.
"Then what about me? Since I've already opened by solar plexus, and you once said Autarch had my mystic mark, can it be considered that I've already formed and etched this mystic mark? But it shouldn't be possible since I clearly don't have any magic core at that time." Jacob questioned sternly.
"Tsk, tsk, always asking logical questions without missing even the slightest gap, making my life difficult but interesting. Hah, in your case, when you opened the solar plexus, you have indeed formed your mystic signature.
"But do you know why solar plexus is connected with mystic signature, to begin with, and why this method is considered legendary? The mystery lies with the solar plexus, and why it can contain lifeform within, and trust me, this entire topic is way out of your league and from what I can disclose right now with all the information you've acquired.
"All I can comment on this is the solar plexus is where you will find your unique mystic signature, so anything that goes there will naturally contain your mystic signature. But you are far, far away from controlling your solar plexus and discovering its wonders. The Brain Hunter is a special case, and you know exactly why.
"But you have taken a huge step forward after opening your solar plexus and how to walk forward. It's up to you to discover just like you always have. If you need my guidance, then you know how to seek it, hehehehe…"
A contemplating look appeared in Jacob's eyes as well as a helpless light gleaming into his eyes, and he sighed ruefully, "If you could just properly reveal everything, then I don't think there is anything in the world that can be our match. But you insist on putting on all these restrictions. I'm starting to understand why your inheritors always ended up dead and you in some ditch afterward."
"Hahahaahha… that kind of hurts, you know. But trust me, these restrictions are real, or where's the fun in revealing everything and making things easier and walking on a flowery path?
"Are you sure you want immortality, not some cabbage that you can buy with money? Besides, going through all these hardships will make you someone worthy of immortality and cherish it.
"If you don't have the will to suffer hardships and overcome them, then you better just give up now and enjoy the remaining lifespan you have earned…"
Jacob, for the first time, felt Immortika was serious, but he couldn't tell just by writing. Nevertheless, those words were enough for him to understand that there was no point in pursuing this stubborn yet eccentric book.
In the end, he sneered, "I'll have all the time to enjoy once I become immortal!"
