The soul acts as a vessel, and the energy it contains is referred to as soul energy, which can be transformed into a **Soul Crystal**.
In the eyes of many wizards, soul energy is one of the most versatile energies in the multiverse.
Unlike elemental energy, which many beings cannot absorb, soul energy is universally absorbable and usable.
Soul energy can be said to be the most widely applicable energy across the multiverse.
A Soul Crystal, on the other hand, is the product of a soul dissipating after a life ends, a condensed form of soul energy.
Unfortunately, Soul Crystals are difficult to produce naturally; only certain special entities drop primitive Soul Crystals.
In most cases, wizards obtain Soul Crystals through artificial means.
To artificially create a Soul Crystal, a vessel must be prepared.
The most commonly used vessels are various gemstones.
What Sunan was currently doing was the process of artificially creating a Soul Crystal.
Amidst the unwilling shrieks, one ghost after another was drawn into the gem, causing its color to gradually shift towards gray.
In just a short time, the vengeful spirits surrounding Sunan were completely absorbed.
"Is that all?"
Sunan looked expectantly at the evil spirit.
Only this few vengeful souls were insufficient to fully transform the gem into a Soul Crystal.
Seemingly provoked by Sunan's gaze, the evil spirit let out a piercing scream and unleashed a wave of negative energy.
Unfortunately, the attack was intercepted by his Shield spell.
Seeing this, the evil spirit leaped into the air and lunged at Sunan.
"Is this all the vengeful souls you have?"
Sunan frowned in dissatisfaction. Ignoring the charging evil spirit, he began to chant complex and obscure syllables.
He currently had three layers of protection set up.
Shield spell, energy particles, and the Protective Ring.
Additionally, a Rune Gem was ready in his palm, prepared for activation.
He had no concerns that the evil spirit could breach his defenses in a short time.
As expected, when he was ready to cast his spell, the evil spirit's claw-like hands couldn't even break through the Shield.
**Magic Missile!**
Three fist-sized missiles shot forth, piercing through the evil spirit's ethereal body like bullets. The spirit emitted a horrendous shriek, and its form visibly dimmed.
Sunan remained unfazed, calmly unleashing a second Magic Missile.
The combat quickly escalated.
The evil spirit completely abandoned defense—though, in truth, it couldn't defend—constantly changing direction to attack Sunan, desperately trying to break through and tear him apart. Unfortunately, every attempt was thwarted by the Shield.
Sunan focused on launching his Magic Missiles.
By the time the evil spirit managed to tear through the invisible barrier, it had already taken four hits from the Magic Missiles. Its once semi-transparent form looked even more insubstantial, as if it might dissipate at any moment.
At this point, the evil spirit finally realized the danger and attempted to retreat.
Unfortunately, it was too late.
Releasing the fifth Magic Missile, Sunan then raised the gem in his hand.
Before the evil spirit could regain its composure after being hit by three more missiles, it was pulled toward the gem by an overwhelming invisible force.
Despite its frantic struggles, it was unable to resist the gem's power, ultimately being drawn entirely into it.
With the soul's absorption, the gem transformed completely, becoming a gray crystal!
"Got it!"
A smile of satisfaction appeared on Sunan's face.
Under normal circumstances, he would need the souls of dozens of knights to create even the lowest-grade Soul Crystal.
However, with his current mental power, he couldn't extract souls from corpses directly; he could only rely on certain magical items or formations—unfortunately, he had none.
But with the vengeful evil spirit, it was much simpler: weaken their power with a beating and then forcibly absorb them.
One evil spirit was worth the souls of twenty to thirty knights.
Stowing the crystal away, Sunan turned his gaze toward the Bloodstained Mandrake nearby.
The evil spirit was essentially a manifestation of the Bloodstained Mandrake's concentrated power, free from the constraints of its floral form.
Thus, with the evil spirit's demise, the Bloodstained Mandrake suffered a heavy blow, visibly wilting.
Its size shrank significantly, now standing less than twenty centimeters tall.
When Sunan pulled it from the ground, the Bloodstained Mandrake emitted a sharp, piercing scream, struggling violently to burrow back underground. However, its weakened state couldn't resist Sunan's strength, and he forcibly stuffed it into a silver-plated box.
The box's surface was engraved with a sealing array that could contain the Bloodstained Mandrake's mental energy.
As long as the box remained closed, the Bloodstained Mandrake wouldn't pose a threat.
Having completed these tasks, Sunan dusted off his hands and surveyed his surroundings.
With the lurking evil spirit eliminated and the Bloodstained Mandrake sealed, the other Mandrakes in the estate began to wither and die in large swathes.
Soon, the environment returned to normal; aside from some dilapidation, there were no signs of abnormalities.
However, the air still contained a significant amount of negative energy particles, making it uninhabitable for the time being. Naturally dissipating, it might take four to five months to return to normal levels.
Of course, if a witch apprentice were to purify the area, it could return to normal in just a few days.
But Sunan wasn't willing to undertake such a task without compensation.
To be honest, a thousand gold coins for taking down an evil spirit was quite a bargain.
Were it not for the Bloodstained Mandrake and the Soul Crystal, he wouldn't have accepted such a job.
Outside the estate, the Silvermoon Viscount paced back and forth, occasionally glancing at the estate, his anxiety palpable.
Not long after Sunan entered, flames erupted within, followed by a cacophony of screams that left him on edge.
He considered sending people in to investigate but hesitated, fearing the risks.
He was sweating nervously.
Fortunately, it wasn't long before Sunan emerged from the estate.
"Sir Ang."
The Silvermoon Viscount rushed to greet him, seemingly hesitant to speak.
Sunan stated calmly, "The evil spirit has been eliminated."
Upon hearing this, the Viscount let out a long sigh of relief.
"There are still many negative energy particles lingering in the estate; it shouldn't be inhabited for at least six months," Sunan added as a reminder.
The Viscount nodded, understanding.
In truth, he wouldn't have considered reassigning the estate anyway.
Given the bizarre events that had transpired, it would likely remain closed and abandoned.
But it didn't matter; as long as Clockstone City remained unaffected, he wouldn't mourn the loss of a mere estate.
"Thanks to you, Sir Ang, I've arranged a banquet in your honor. I hope you'll grace us with your presence."
The Silvermoon Viscount spoke warmly.
Having encountered such a powerful wizard, he certainly wouldn't let him leave so easily.
If he could recruit Sunan to his territory, he would gladly grant him a town even if it meant losing a small fortune.
Unfortunately for the Viscount, Sunan declined without a second thought.
"No thanks, I have matters to attend to."
With that, he turned and left without waiting for the Viscount's response.
At that moment, a guard rushed over from a distance, brushing past Sunan.
Before Sunan had gone far, his keen hearing allowed him to clearly catch the guard's hushed report to the Silvermoon Viscount.
"My lord, the Baron Shining has declared war on Blackstone City!"
