Where the shout came, Dumbledore appeared outside the wall of fire that Quirrell had unleashed.

Facing the barrier of the fire wall, after Dumbledore shouted to stop Kewen, a 'Apparation' passed through the fire wall and appeared beside Kewen.

First, he glanced solemnly at the remnant of Voldemort's efforts to gather, and then Dumbledore said to Cowan sternly: "You can't use that magic!"

Just when Cowan thought Dumbledore would continue to reprimand him, he didn't want the other party to suddenly raise his hand.

The wand in the shape of a phalanx was lifted by Dumbledore, and a green light suddenly shot out from the tip of the wand, instantly hitting Voldemort's remnant soul.

It was only at this point that Dumbledore's voice sounded again: "Avada Suo!"

Bang!

After the green light of the death curse hit Voldemort's remnant soul, the green glow from the inside out suddenly burst Voldemort's remnant soul.

After a faint, short scream, Voldemort's remnant quickly melted into the air, and finally there was nothing left.

Dumbledore's actions not only stunned Cowen, but even Harry, who was always confused by the situation, was stunned.

At this time, Dumbledore was inexplicably relieved, slowly put down his wand, turned his head to stare at Cowen and said solemnly: "How could you use the Death Curse just now!?"

Kewen was stunned and recovered, and then said apologetically: "I'm sorry, Mr. Principal, I have tried almost all spells, but I can't destroy Voldemort, so..."

Dumbledore raised his hand, patted Kewen on the shoulder to interrupt, and then said with a sigh, "Don't forget me and the professors."

His eyes became a little complicated. Dumbledore looked at Cowen and said in a low voice, "You just need to keep trapping him and wait for us to deal with it, instead of using the Death Curse yourself."

After a pause, Dumbledore shook his head: "No matter how many reasons there are, you can't use any black magic!"

"Feel sorry……"

Cowen heard it, and it was obvious that Dumbledore didn't mean to be harsh, and was really thinking of him.

Therefore, Kewen felt that he should explain, so he said: "I actually wanted to notify the professors first, but my 'Guardian Charm' has been keeping Voldemort in check, and there is no way to notify the professors."

"Okay, let's not talk about that."

Dumbledore raised his hand on Corwen's shoulder, lowered it again and patted it lightly, then turned to look at Harry Potter, who was still stunned there.

"How are you, Harry?" Dumbledore asked softly. "Is there any injury? I don't think you're in good shape."

"No, I mean...I'm fine! I'm fine!" Harry Potter finally regained his senses, and then hurriedly said with some confusion: "It's Professor Quirrell and Senior Quinn! I mean before! Here they are...and Voldemort..."

Listening to the other party's inconsistency, Dumbledore shook his head, walked to Harry's side, and said softly, "Okay, okay, calm down, let's talk slowly."

"Yes, yes, Mr. Headmaster!" Harry Potter took a deep breath, then glanced at Cowen with some fear, and quickly retracted his gaze.

"So." Dumbledore asked warmly, "Have you got the Philosopher's Stone?"

"The Philosopher's Stone?" Harry was stunned for a moment, then shook his head quickly: "No, I haven't seen the Philosopher's Stone! Professor Quirrell was going to take me to find it just now, and then..."

Glancing at Kewen again with some fear, Harry continued: "Then Senior Quinn...the professor's hand suddenly...I don't know what happened, after the professor touched my hand, it suddenly became like that... …”

Finding that Harry Potter still couldn't calm down, Dumbledore sighed secretly, then turned to look at Cowen: "So, where are you?"

"No." Kewen shook his head: "Professor Quirrell used the 'Illusory Body Charm' to go to the dormitory to control me,

But his Imperius Curse was blocked by my Occlumency. "

Kewen started to narrate clearly: "Afterwards, I came here with him pretending to be a hit. Because I have been maintaining Occlumency, I didn't see anything in the magic mirror."

"So it is." Dumbledore sorted out the cause and effect, and understood why Kewen was here.

After thinking of something, Dumbledore asked jokingly, "Is Quirrell the level you left behind?"

"Yes." Kewen was a little embarrassed: "After that, I deliberately kept the floor tiles open, in order to save some time for later supporters."

Dumbledore recalled the deception Kewen left behind, and couldn't help curling the corners of his mouth. He looked back at Harry again, and there was a hint of helplessness in his eyes.

"Okay." Dumbledore made a decision: "Kewen, take Harry and the two students who stayed above to the infirmary, and help me inform the professors."

With that said, Dumbledore looked at the ashes and clothes that Professor Quirrell left behind, and said with some regret, "I have to stay and deal with it."

"Okay professor." Cowan obediently walked to Harry's side and greeted, "Let's go, Mr. Potter."

Harry was a little reluctant to leave, all because of Cowen's previous actions, which left a terrifying impression on him.

Dumbledore noticed Harry Potter's hesitation, and said warmly: "Go, Cowen will arrange for you."

"Okay, okay." Harry Potter nodded helplessly, raising his legs to follow Kewen's footsteps.

The wall of fire caused by Professor Quirrell was just an ordinary flame, and it was fine to scare a wizard of Harry's level. With just a wave of his hand, Cowen extinguished the wall of fire with the Extinguishing Charm.

Passing through the potion room and the troll room, in the chessboard room, Cowen saw Ron in a coma and Hermione who was taking care of Ron.

Use the transformation spell to turn the broken pieces into a stretcher, and then use the floating spell to control the stretcher, and take the protagonist trio to return the same way.

Walking behind, Hermione looked at Kewen's back, then leaned over to Harry, winked, and asked silently, "What's going on?"

Harry glanced cautiously at Cowen's back, then shook his head quickly, and answered equally silently, "We'll talk about it later."

Not long after, the group completely left the forbidden area.

Kewen sent the news to Professor McGonagall with the 'God Guard' for the first time, and then took the trio all the way to the infirmary.

After handing the three to Madam Pomfrey in the infirmary, and briefly explaining the situation, Cowen simply stayed in the infirmary to prevent Dumbledore or the professors from looking for him in the future.

After finding an empty bed and sitting down, Cowen asked Harry and Hermione. "Want something to eat?"

The two were stunned, not knowing how to respond...
