"It's a pity that these secret arts are not recorded in detail in ancient books," Qin Yun said, his expression full of regret and disappointment.
If he could have recorded the secret arts in detail, he couldn't even imagine how much stronger humanity would have become.
Leaving aside other secret arts for now, just look at the Soul-Snatching and Spirit-Extracting Secret Art.
It could obtain a Spirit Essence from a demon with 100% certainty.
The value of this secret art was simply immeasurable!
If this secret art had not been lost, Spirit Essences would not have been scarce at all, and everyone's magic could have been strengthened to Level 5 or even Level 6!
From this, one could further imagine how many powerful secret arts and forbidden arts humanity once possessed.
So powerful that they were enough to make those totem creatures that ruled the world either die or be injured, almost disappearing from this world.
If it weren't for Mo Fan's in-depth excavation of totems in the future, most people would probably never know of the existence of totems.
Looking at it this way, history seemed to have been deliberately erased by an invisible hand, becoming fragmented and incomplete.
Jiang Yuan always felt a chill down his spine when he thought of this.
There were simply too many secrets in the world.
"Forget it, let's not talk about these upsetting things anymore. You haven't contracted an Undead yet, have you? Let me tell you about the Undead Contract."
Qin Yun composed himself and changed the subject.
Jiang Yuan had previously told him that he hadn't undergone an Undead Contract yet.
"The Undead Contract is actually similar to the Summoning Contract, but there are also differences. You can create your own Undead, and the Undead you create are not restricted by contracts, but the creation process is extremely complex and the cost is quite high."
Only those Undead Mages from Egypt, relying on their abundant Undead resources, had the ability to create Undead.
Qin Yun said, "For the current Undead System, the most typical characteristic of the Intermediate-Level is the opening of the Netherworld Space, which allows for the signing of an Undead Contract."
"The Netherworld Space and Summoning Space have similar names and functions, but they are actually very different."
"The size of the Netherworld Space will expand as your magic level increases, so even if you contract more Undead, a second Netherworld Space will not appear. This is a fundamental difference between it and the Summoning Space."
"Generally speaking, an Intermediate-Level Mage's Netherworld Space is about the size of a basketball court, reaching the size of a football field at High-Level, and ten football fields at Advanced Level."
These words made Jiang Yuan fall silent.
He secretly glanced at his own Netherworld Space.
Good heavens!
The size of his Netherworld Space was as large as twenty football fields.
It was twice the size of a Advanced Level Netherworld Space!
It seemed that the Netherworld Space granted by his innate talent was indeed very different from an ordinary Netherworld Space.
Jiang Yuan understood in his heart that it was best to remain silent at this time.
"The Netherworld Space is filled with Undead aura. This aura can not only nourish Undead but also, to a certain extent, repair the damage suffered by Undead. As long as it's not a fatal injury, they can basically recover," Qin Yun continued to speak.
After finishing his explanation of the Netherworld Space, Qin Yun erased the writing on the blackboard and began to explain the Underworld.
"The Underworld belongs to the Dark Plane, and the source of Black Magic comes from there. The entire Dark Plane is ruled by the Dark King."
"No one knows how powerful the Dark King truly is. There are Black Mages among Forbidden Spellcasterss. As the birthplace of Black Magic, one can imagine that the Dark King's strength is beyond our imagination."
The chalk in Qin Yun's hand paused on 'Underworld', and after a moment, he crossed out 'Underworld': "Unfortunately, we know very little about the Dark Plane. We haven't even figured out our own plane, let alone exploring other planes."
Rewriting "dark matter" on the blackboard, Qin Yun said, "You'll be coming with me to the Ancient Capital in a while. Let me tell you about dark matter."
"All Black Magic relies on dark matter for enhancement, just as elemental magic relies on elemental seeds. How much do you know about dark matter?"
Qin Yun recalled that Jiang Yuan had previously brought up dark matter, so he assumed he knew quite a bit.
Jiang Yuan replied, "To absorb dark matter, one must sign a contract with it, and then one can gain some special abilities."
Qin Yun shook his head: "You're only half right."
Only half right?
Jiang Yuan was a little confused. Was there something he didn't know?
Qin Yun continued to explain.
"What you said earlier is correct; absorbing dark matter is essentially signing a contract with it, exchanging a certain price for power. But the latter part is incorrect; special abilities are not so easy to obtain."
"Many Black Mages, after signing a contract, only get an enhancement to their summoned or contracted Undead. Special abilities are extremely rare, and only those with extremely good luck can possess them."
"Hmm?"
Upon hearing this, Jiang Yuan's pupils slightly contracted.
So, by signing a contract with the dark matter given by Dean Xiao, his luck was considered off the charts?
Qin Yun noticed the change in his expression and asked with a smile, "Judging by your expression, did a Black Mage by your side gain a special ability after signing a contract with dark matter? Haha, that person's luck is really good."
"Me." Jiang Yuan extended his finger and pointed at himself.
"What?" Qin Yun didn't react for a moment.
Jiang Yuan explained, "What I mean is, I gained a special ability."
"Ah?" Qin Yun's eyes widened, his face full of shock. "Where did you get dark matter? Didn't I not give it to you yet?"
dark matter was quite valuable, costing tens of millions, so how could Jiang Yuan afford to buy it?
Jiang Yuan quickly reminded him, "The reward from the arena challenge."
Qin Yun then had a sudden realization: "So it was Dean Xiao who gave it to you. I almost forgot about that. But you actually gained a special ability the first time you signed a contract. Your luck is much better than mine was back then."
dark matter and absorbing elemental seeds have similarities; neither can be stacked.
Subsequent absorption of dark matter would overwrite previous ones. Although the gained bonus would certainly be higher, it was unclear by how much.
Moreover, the probability of gaining a special ability would only slightly increase.
Qin Yun recalled that he only managed to acquire a special ability at the High-Level.
Although dark matter in the Ancient Capital was relatively easier to obtain, the price was still very expensive.
Thinking of these things, Qin Yun felt a pang of heartache.
He couldn't suppress his curiosity and asked, "What special ability did you gain? And what was the price you paid?"
Jiang Yuan explained, "It's called Undead Tentacles, and the price is magic energy. Would you like me to demonstrate its effect?"
After getting Qin Yun's consent, Jiang Yuan circulated his Undead aura, condensed Undead Tentacles, and demonstrated them in front of Qin Yun.
The power of these Undead Tentacles was indeed impressive.
However, Qin Yun's attention was not on the power at all, but was drawn by the price Jiang Yuan mentioned.
"Are you saying that the price you paid was merely a bit of magic energy?"
"Yes."
"Hiss!" Qin Yun gasped, "It seems you don't realize that in the eyes of Black Mages, a contract with magic energy as the price is considered a top-grade contract!"
Upon careful thought, one could understand why it was a top-grade contract.
Magic energy could be restored, almost like an inexhaustible resource. Using magic energy as the price was simply too cost-effective!
"You don't even know what the price for my contract was, Teacher, it was Spirit Essences!"
