Another half a month passed.
Feng Zhoulong called in a hurry, sounding like he had something urgent.
Jiang Yuan thought it was about the Fusion Magic making progress, so he rushed to the Research Institute without delay.
In the laboratory, the imperial jade seal was enveloped by a mass of deathly liquid, and even the surrounding vessels showed signs of corrosion.
"Brother Jiang Yuan, I've already figured out the secret of the imperial jade seal. Do you want to know?" Feng Zhoulong said mysteriously.
Indeed, Feng Zhoulong's talent in magic research was too strong; it hadn't been long, and he had already uncovered the secret.
Jiang Yuan quickly asked, "Old Feng, stop teasing me. What's the secret of the imperial jade seal?"
Feng Zhoulong was very easygoing; even with a significant age difference, calling each other brothers seemed like a common thing for him.
Feng Zhoulong didn't answer immediately, instead asking, "Do you know the levels of demons?"
Of course, he knew.
From Servant to Emperor, Mingzhu Academy's classes had covered it.
Jiang Yuan immediately stated that he knew.
Only then did Feng Zhoulong say, "Knowing is enough. According to our research, the imperial jade seal is a Heavenly Vessel, and it's an Undead System Heavenly Vessel. This aligns perfectly with its legends."
If it were the imperial jade seal that had been passed down to this day without ever being damaged, it would certainly correspond to an Emperor-level magic tool, like the Black Dragon Emperor's set.
However, a corner of the imperial jade seal was once damaged, and later monarchs had it inlaid with a golden corner.
So, it could only be considered a Heavenly Vessel.
But even this was already a rare and unique treasure in the world.
However, that wasn't Jiang Yuan's focus. He continued to ask, "Then have you researched what it's attracting?"
Feng Zhoulong shook his head, "We don't know exactly what it's attracting."
"Didn't you say you'd already figured it all out?" Jiang Yuan asked, puzzled.
Feng Zhoulong felt a bit awkward hearing that, "I did speak too soon, but we really don't know what it's specifically attracting. The only thing we can confirm is that it's related to the Ancient King; the spatial coordinates on it are guiding an unknown object related to the Ancient King."
This was like attracting an iron object with a magnet through a curtain; no one could be sure if it was attracting an iron ball or an iron pot.
"..."
"Then is there any way to stop the imperial jade seal's guidance?"
Jiang Yuan's question hit Feng Zhoulong right in the heart. He swept away his previous awkwardness and confidently declared, "Of course there's a way! As long as the imperial jade seal recognizes you as its master and you place it in your Netherworld Space, it can be stopped!"
"The imperial jade seal is currently masterless!"
"Have the imperial jade seal recognize me as its master?" Jiang Yuan was slightly stunned.
A Heavenly Vessel just given to me like that?
Does Old Feng's authority extend that far??
Jiang Yuan didn't understand the exact status of the Research Institute.
In fact, their authority was precisely that great.
Any research materials that entered the Research Institute could be freely disposed of by them.
Although they focused solely on magic research, their magic cultivation was not weak at all.
For example, Feng Zhoulong was a Super-Order Mage.
Another example, Dean Xiao, who was seen as a scholar by many, was a top Forbidden Spellcasters.
However, only Feng Zhoulong had the authority to dispose of a Heavenly Vessel. Those above him would at most question him, but they wouldn't make things difficult for him.
Heavenly corresponds to Commander-level. An Emperor-level vessel would not receive much attention.
"That's right! If you put it in your Netherworld Space, not only will the Netherworld Space expand tenfold, but it will also greatly accelerate the growth rate of your contracted Undead!" Feng Zhoulong said excitedly.
Then he changed the subject and said, "But you have to promise me one thing: research the feasibility of Fusion Magic with me in the future."
He was interested in Jiang Yuan's creative thinking.
Although it was somewhat naive and simple, it might produce unexpected results!
Upon hearing this, Jiang Yuan thought, was there any reason to refuse?
"Okay, I promise!"
"Good! You can prepare to make it recognize you as its master now. I'll teach you how to do it!"
Subsequently, Feng Zhoulong immediately pulled Jiang Yuan to the imperial jade seal and meticulously taught him how to perform the recognition ritual.
An entire day passed.
As Jiang Yuan exhaled a breath of stale air, the imperial jade seal in the laboratory vanished without a trace.
Recognition successful!
Jiang Yuan's Netherworld Space instantly expanded tenfold.
After reaching High-Order, the size of the Netherworld Space was already almost boundless.
With the addition of the imperial jade seal, it became even more vast and endless!
At this terrifying size, Jiang Yuan felt that accommodating the Sha Abyss would be effortless.
If he reached Advanced Level, how many Undead would he be able to accommodate?
Jiang Yuan felt that his development of the Undead System was still too limited.
He could completely desperately create Undead and throw them into the Netherworld Space.
What about the Sha Abyss?
His Netherworld Space was another Sha Abyss!
"How is it? Has your Netherworld Space changed?" Feng Zhoulong asked with concern.
Jiang Yuan nodded, "There has indeed been a change."
Feng Zhoulong laughed heartily, "The imperial jade seal was once a supreme treasure in the hands of the Ancient King. Now that it's in your hands, you might also become a figure like the Ancient King."
"Thanks for the kind words, Old Feng." Jiang Yuan had already decided to transform his Netherworld Space into another Sha Abyss.
"Oh, right," Feng Zhoulong remembered something and said, "Your Three-Eyed Underworld General has successfully advanced to Commander-level, but it has now lost contact with the Underworld and cannot return there."
"Huh?"
The head of the Three-Eyed Underworld General had accompanied Jiang Yuan to the Research Institute.
The generous Feng Zhoulong, upon hearing about the Three-Eyed Underworld General's peculiar state, wanted to study it. With a wave of his hand, he covered all the advancement materials.
So, the Three-Eyed Underworld General had remained in the Research Institute, calmly advancing to Commander-level.
"However, this is also a good thing. It no longer needs your magic energy to maintain its existence in the main plane," Feng Zhoulong said.
Despite this, Jiang Yuan still couldn't understand, "How is this a good thing? If it can't return to the Underworld, won't it have to stay by my side all the time? That's too inconvenient!"
"No, you can break the previous contract with it and re-sign an Intermediate-level Undead contract. That way, you can put it in your Netherworld Space," Feng Zhoulong said, shaking his head.
"That's good, that's good." Jiang Yuan smiled.
Feng Zhoulong took Jiang Yuan to see the advanced Three-Eyed Underworld General.
The Commander-level Three-Eyed Underworld General's physique had once again undergone a tremendous transformation.
Its body soared to an astonishing height of twelve meters, its bones becoming increasingly thick and sturdy, with every inch of white bone exuding a chilling sense of power!
Above its head, mysterious purple patterns like ancient runes spiraled into view, its two eyes glowing with eerie green fire, emanating endless gloom and strangeness.
And the third eye in the center of its forehead now blazed with purple flames!
The purple flames of the Specter bestowed the Three-Eyed Underworld General with power from the Psychic!
