Facing the overwhelming barrage of gunfire, Quirrell immediately cast a powerful version of the Shield Charm on himself.

Then he spun around, seemingly intending to Apparate away from the location.

In his panic, Quirrell seemed to have forgotten that this area was still within the anti-Apparition charm of Hogwarts Castle, making it impossible to Apparate to escape.

Countless bullets struck the powerful shield formed by the spell, sparks flew everywhere, and the sound of "clang, clang, clang" was incessant.

But there were simply too many bullets, and the collision sparks were rapidly diminishing.

Feeling the magic within him rapidly draining, Quirrell panicked again. He knew that Lord Voldemort had more important things to do this time and could not spare any attention for him.

"Chen Yu, stop! I have many Galleons! I can give you many Galleons!"

Quirrell thought Chen Yu was in dire need of money; otherwise, why would he sell those miscellaneous items at Hogwarts?

Seeing that Chen Yu was not interested in Galleons, he immediately changed his offer: "While teaching Defense Against the Dark Arts Class, I used my position to acquire many magical items. As long as you spare me, all these things are yours!"

The roaring sound of ten M61 Vulcan cannons prevented Chen Yu from clearly hearing Quirrell's pleas.

He could only see that Quirrell was still stubbornly resisting, so he naturally wouldn't stop until the entire magazine of bullets was expended.

By the time Chen Yu saw Quirrell raise his hands in surrender, it was too late.

The metal torrent had already broken through Quirrell's protective spell. In just a few seconds, hundreds, even thousands, of bullets struck Quirrell's body, directly turning him into a bloody mess.

Even a wizard with strong vitality, their flesh and blood could not withstand the power of a Vulcan cannon.

Quirrell was dead beyond dead.

Looking at the blood-splattered, bloody human flesh, Chen Yu also felt a wave of nausea.

He withdrew his clone, put all the M61 Vulcan cannons back into the Serenitea Pot, and used a Cleaning Charm to clean up the disgusting pile of flesh.

With a gentle wave of his wand, the splattered blood, brain matter, organ fragments, minced meat, and bone fragments on the ground all vanished.

The Cleaning Charm truly was a good helper for wizards in murder and robbery.

If one were to use the Fiendfyre Charm beforehand, even the ashes would be completely removed.

Chen Yu's thoughts were correct; with Quirrell's death, the black mist began to dissipate rapidly.

The empty room returned to normal.

Chen Yu turned around and saw Harry.

At this moment, Harry stood before the Mirror of Erised, struggling with himself.

"Take out the Philosopher's Stone!"

"No! I won't let you succeed!"

Harry's right hand was gripping his left hand, and his left hand was trying to pull something out of his wizard's robe pocket.

Harry's face alternated between ferocious and anxious expressions.

"Potter, don't you want your parents to be resurrected anymore?"

"You liar, scoundrel, murderer, I don't believe a single word you say!"

Through the reflection of the Mirror of Erised, Harry saw Chen Yu and immediately shouted, "Chen Yu, come quickly and stop me! I've been possessed by Lord Voldemort! The Philosopher's Stone is in my pocket, and Lord Voldemort wants to get it!"

Harry's voice became somewhat high-pitched. He immediately turned around and continued to shout at Chen Yu, "Quick, quick, use a spell to control me! I can't hold on much longer! Then go find Professor Dumbledore; he definitely has the ability to extract Lord Voldemort from my mind!"

"Hehehe, it's useless, useless, useless!"

"Harry, that old immortal Dumbledore isn't as deeply knowledgeable in soul research as I am. It's impossible for him to remove me from your brain! Just accept your fate, Harry. Once Dumbledore knows I'm possessing you, he'll kill you without hesitation! Don't resist anymore; why not let me take out the Philosopher's Stone and then use its power to mold a body for me? That way, everyone will be free!"

"Lord Voldemort, you're dreaming! I won't let you succeed!"

"Since you don't agree, then offer up your own body, Harry!"

Harry was arguing incoherently with himself.

Chen Yu was not clear on how Lord Voldemort's soul had possessed Harry during the time he was trapped by the black mist.

Either Lord Voldemort used sweet words or hypnosis to deceive Harry, causing Harry to temporarily open his heart and agree to Lord Voldemort's possession.

Or, after Lord Voldemort's soul emerged from Quirrell's body, he sensed his own soul fragment on Harry's forehead, found a gap, connected his soul with Harry, and thus invaded Harry's mind and was corroding him.

But no matter what, Lord Voldemort, freed from the constraints of Quirrell's body, was no longer afraid of Harry's touch-face kill.

After all, Lord Voldemort was now almost completely controlling Harry's body, and the power of "love" left by Lily could not harm Harry himself.

"Harry, hold on a little longer. I'll be right back."

When Chen Yu thought about matters of the soul, the first thing that came to mind was the Ancient One's slap to Doctor Strange.

One slap separated Stephen Vincent Strange's soul from his body, making Strange realize for the first time that magic truly existed in the world.

This ability is called Astral Projection, also known as soul projection.

Chen Yu quickly went offline, logged into the Iron Man Game World, then swiftly canceled his clone in that world, retrieved the knowledge he had recently learned, immediately went offline, and logged back into The Magical World of Hogwarts.

Harry only felt Chen Yu disappear instantly and then return instantly.

This time, the clone did well; it actually learned the ability of Astral Projection in the Iron Man Game World.

Chen Yu quickly approached Harry and slapped him on the chest.

Huh, the feel was not right... Just as Chen Yu was a little surprised, he saw three spirits rolling out of Harry's body.

The one wearing a Gryffindor Little Wizards robe was Harry's soul.

Another was Lord Voldemort, with only a face remaining, his eyes closed, emitting black mist, and unresponsive to the outside world; this was the fragment of Lord Voldemort's soul hidden within Harry.

The last one, with all four limbs complete and also composed of black mist, was Lord Voldemort's main soul, which had possessed Quirrell.

"My soul was slapped out of my body by you? That's too amazing, Chen Yu! How did you do it?"

Harry looked at his transparent body in disbelief, then gave Chen Yu a thumbs up.

When Chen Yu saw the Oath Ring exposed on Harry's arm as he gave him a thumbs up, he realized why the feel had been off earlier.

It turned out Harry had become Harley.

However, Harry was still young at this time, and the changes in her body were not significant; her features were a little softer, her hair a little longer, but otherwise, there didn't seem to be much change.

Chen Yu looked at Harry's soul and asked, "You put on the Oath Ring?"

"While you were gone, I was no match for Lord Voldemort. If not for it, I wouldn't have lasted that long. Thank you for lending me such a powerful magical item. The Oath Ring truly granted me powerful magical strength, just as you said."

As Harry's soul spoke, it materialized two Desert Eagles: "These are the two weapons the Oath Ring granted me. One is called Black Rose, and the other is called White Rose. They respectively have the effects of cutting and combining."

"The bullets fired by Black Rose can sever any magical effect, and the bullets fired by White Rose can violently stick two unrelated things together."

"As long as I have enough magic, I can pull the trigger and fire bullets indefinitely!"

"It's just that now that I've put on the metal bracelet, I can't take it off to return it to you."

Hearing that Harry still wanted to return the Oath Ring to him, Chen Yu quickly shook his head in refusal.

"No, no, no, I don't need this. Since it can't be taken off, then you just keep wearing it. As long as you like it."

After speaking, Chen Yu began to ponder: Cutting and combining, did the Oath Ring take a shortcut and give Harry the abilities of the origin bullet he had given him, but split them?

While Harry was introducing his newly acquired abilities, Lord Voldemort was not idle either.

In his shock, he quickly flew to his soul fragment and immediately swallowed it.

With the nourishment of his own soul fragment, Lord Voldemort's main soul immediately appeared much more solid.

No longer as ethereal as before.

Seeing Harry chatting with Chen Yu, Lord Voldemort immediately rushed towards Harry's body, wanting to enter Harry's body one step ahead and then manipulate Harry to retrieve the Philosopher's Stone.

Chen Yu had been keeping an eye on Lord Voldemort's movements. Seeing him rapidly approaching, he decisively put Harry's body into the Serenitea Pot, making Lord Voldemort's plan come to naught.
