In the dark and oppressive depths of the underground tunnel.
The pure white fluorescence that originally illuminated the tunnel transformed into a chilling green in almost an instant, which is the Unforgivable Curse released by Ian in a state of anxious fright.
No other choice.
After all, who wouldn't immediately recognize the face atop that deformed creature!
Nose-less Tom!
As the saying goes, in a close encounter, hesitation leads to defeat. Ian certainly didn't want to give the other side a chance to strike, especially since nose-less Tom was, after all, a genuine Black Demon King.
Even if it's just a lingering remnant of a soul, it still remains an evil figure not to be underestimated. Ghosts know if this guy can still cast some insidious and terrifying curses or magic in a soul state.
This was also Ian's first time facing a revived Voldemort in the human world.
"Avada Kedavra!"
Accompanied by Ian's decisive incantation.
The green light arced through the air perfectly, like the scythe of the God of Death, carrying an irresistible aura of death, directly targeting the deformed monster and the remnant soul of Voldemort atop it.
Intending to possess and usurp the little wizard to sneak into Hogwarts and probe how many Horcruxes were found, Voldemort's remnant soul was completely baffled in the face of the familiar green light.
The Killing Curse!
How many years have I been dead?
Since when has Hogwarts become so avant-garde!
To see my signature move on a seemingly half-sized lower-year student? Is this dwarf pretending to be a little wizard or an old man with gnome blood!
"Hiss~"
Voldemort's remnant soul never considered defending, after all, he felt he was facing a little wizard who could only play with the Wingardium Leviosa spell. This led to him being unable to cast any responsive measures in time.
The creature he possessed had no escape in the underground tunnel, and as the green light approached, the deformed monster seemed to sense the impending doom. Its massive body began to shudder violently, the deformed limbs flailing helplessly, trying to block the incoming fierce magic beam.
However.
The death-representing spell wouldn't stop for this. Everything was destined, and even if it only hit the limbs, the deadly "web" would still instantly spread across its entire body.
It infiltrated the soul like maggots on bones.
Perhaps this was a kind of relief for the creature, after all, being possessed by Voldemort's remnant soul, the experience was definitely more painful than a terminal cancer patient. Its body was twisted and deformed, its skin covered in strange lines and lumps, like a ghost crawling out of hell.
"Bang~"
The domineering and irresolvable nature of the Unforgivable Curse was showcased at this moment. Although the massive deformed creature might have considerable magic resistance, it still couldn't even let out a cry of despair.
With a dull thud, the deformed creature collapsed to the ground, splashing a large puddle of foul-smelling water, which Ian blocked with an umbrella in his other hand as a shield.
"Hu~"
As the green "web" enveloped further into the soul, large plumes of black fog fumed from the corpse, and Voldemort's remnant soul clearly used the soul of the creature it possessed as a shield.
Billowing black fog.
The black fog rolled and swirled, oppressive and filled with a terrifying gloom like an endless dark ocean, carrying an indescribable eeriness and malevolence.
"Impossible! The Killing Curse!! You're not a student of Hogwarts!!!"
Voldemort's remnant soul was hidden within it.
He had no intention or plan to attack Ian. After leaving the carcass, he dashed out immediately. This very decisiveness also stemmed from the Black Demon King's caution and keen magical intuition — Voldemort's remnant soul discovered that the Killing Curse, which killed his "temporary body," did not disappear after the creature's death.
"How can this be!"
Feeling the web above coalesce again, poised to attack, Voldemort's remnant soul realized he had genuinely encountered something ghostly in this dark place today!
"What did you do to the Killing Curse!"
Indeed, Voldemort's remnant soul's perception wasn't wrong. As his soul barely escaped, the green web on the deformed creature's corpse already converged and shot forth.
It only took two seconds either way.
"Boom!"
As the eerie green light once again rushed towards him, Voldemort's remnant soul dared not be careless, directly manipulating the surrounding billowing black fog to topple the walls of the underground passage.
The deadly green light got blocked by the shattered wall and displayed a web-like image on the wall; however, this time it did not regroup but gradually disappeared.
"Phew, phew... thankfully my Avada Lightning Chain has just reached an initial stage." Not only did Voldemort's remnant soul flee in shock, but Ian, in relentless pursuit right behind him, was also taken aback. Through the simple confrontation earlier, the little wizard had sharply realized that probably not much strength was left in Voldemort's remnant soul.
Otherwise.
They wouldn't be so hilariously dodging a Killing Curse. Probably in such a lingering remnant soul state, Voldemort's soul would only know some techniques that don't require much magic power?
This was the hypothesis Ian's mind conjured.
This even awakened his yearning for magic.
