The spell flew out and didn't hit Malfoy, but it bounced off the wall behind Malfoy's ear, shattering the toilet bowl beneath the weeping Myrtle.

Myrtle screamed loudly, the water flooded the ground, and Harry slipped.

Malfoy twisted his face and shouted, "Dig into the ......"

"Blade!" Harry roared on the ground, frantically waving his wand.

White light struck, and Malfoy's face and chest were filled with blood, as if he had been slashed by an invisible sword. He staggered backwards and fell to the waterlogged ground with a thud, making a large splash and his wand falling from his limp right hand.

"No!" Harry looked at Malfoy in disbelief, his mind blank.

He, what did he do? Horse, Malfoy......

He slid and staggered to his feet, running towards Malfoy.

Malfoy's face had turned bright red, and his pale hands clutched his blood-soaked chest.

"No, no, I don't have ......"

Harry felt a pang of remorse that he didn't know what he was talking about, and he knelt beside Malfoy.

Malfoy lay in a pool of blood and shivered uncontrollably, as if he wanted to say something, but he had no strength at all, life was flowing through him, and the weeping Myrtle let out a deafening scream, "Kill! Kill in the bathroom!"

"Don't, don't shout ......"

Bang!

The door slammed open behind Harry, and he looked up in horror: Snape rushed in, his face pale.

He shoved Harry aside, knelt down in front of Malfoy, drew his wand, and moved along the deep gaps caused by Harry's spell, chanting a singing incantation, the bleeding seeming to lessen.

Snape wiped the dirt off Malfoy's face and recited the incantation, and now the wound seemed to heal.

Harry was still watching, stupefied by what he had done, barely realizing that he was also drenched in blood and sewage, and that the weeping myrtle was still sobbing and wailing above their heads.

After Snape finished casting the Spell for the third time, he helped Malfoy up, half-dragging and half-hugging.

"You need to go to the school hospital, there may be some scars, but if you use white fresh in time, maybe even the scars can be avoided, let's go......" Snape said in a cold, angry tone as he walked out with Malfoy in his arms, turning back at the door, "You, Potter, are waiting for me here." ”

Harry didn't think of disobedience in the slightest, and he slowly stood up, trembling all over.

He looked down at the waterlogged ground, which was covered with red flowers, and he didn't even have the courage to tell the weeping myrtle to stop making noise.

She continued to cry and cry, but it became more and more obvious that she had a playful taste of enjoyment.

The feeling of loss slowly returned to Harry, and he realized what he had done, the spell he had used on Malfoy.

The Shadowless Spell of the Blade, it turns out that this is the effect of this spell.

Evan had reminded him a few weeks earlier not to use this magic lightly on his students, and Harry had never thought of it......

He never thought that the power of "Divine Blade" would be so strong, this is black magic!

Will Malfoy be okay? What should he do now?

Before Harry could think about it, Snape returned, walked into the bathroom with a gloomy face, and closed the door.

"Go away. He told Myrtle that she stumbled back into the toilet, leaving an ear-ringing silence.

"I didn't mean to. Harry said immediately, his voice echoing through the cold, wet space, "I don't know what that spell is for, Evan reminded me, but I never thought ......"

But Snape ignored it, and he looked at Harry with half-squinted eyes.

"I obviously underestimated you, Potter!" he whispered, "who would have thought you would have such dark magic? Who taught you that spell? Evan Mason?"

"No, it's not him, it's me, it seems to me. ”

"Where?"

"Yes, it's in a book in the library. Harry scrambled, "I can't remember the title." ”

"Lying. Snape said without hesitation.

Harry's throat was dry, he knew what Snape was going to do, and he could never stop it......

In an instant, the bathroom shook in front of him, and Snape entered his thoughts, and he tried to get rid of all thoughts, but no matter how hard he tried, the Half-Blood Prince's Advanced Potions Maker still vaguely floated in front of him......

Then he saw Snape again, in the middle of the messy, waterlogged bathroom.

He looked into those unfathomable black eyes, hoping that Snape hadn't seen the memory, but ......

"Bring me your bag. Snape whispered, "And all your textbooks, all of them, get them here, quick!"

Arguing was useless, and Harry immediately turned and ran out of the bathroom.

As soon as he reached the hallway, he ran towards the Gryffindor Tower, most of them were walking in the opposite direction, and he was shocked to see him covered in blood, but he only ran forward, not answering the questions that were thrown at him.

To be honest, he was stunned, as if a cute pet had suddenly become ferocious.

Harry didn't understand what the prince had in mind when he copied such a spell into a book.

He had too many questions, and what would Snape do if he saw it?

Would Snape tell Slughorn about this, Harry's stomach churned at the thought of this.

How did he get good grades in Potions this school year?Would he have confiscated or torn up the book that taught Harry so much, the book that had become like a mentor and a friend? Harry couldn't let that happen, he couldn't ......

He had to do something, he had to hide the book.

"Oh my God, Harry, where have you been? Why is it wet, is that blood?"

Ron stood at the top of the stairs, looking at Harry in confusion as he had just finished vomiting and had come out of the boys' bathroom.

"I need your book, hurry. Harry panted, "Your potions textbook, bring it to me, get it to me......"

"But the half-blood prince ......"

"I'll explain later! It's too late!"

Ron pulled Advanced Potions from his bag and handed it to him, and Harry rushed into the common room, grabbed his bag, and despite the surprised gazes of several people who had finished eating, he slipped through the portrait hole and scurried down the eighth-floor corridor.

He suddenly stopped in front of the tapestry where the trolls danced, closed his eyes and began pacing back and forth.

"I need a place for me to store my books, I need a place for me to store my books, I need a place for me to store my books......"

He walked back and forth three times in front of the empty wall, and when he opened his eyes, he finally saw the door of the Room of Requirement.

Harry pulled it open and rushed inside, slamming the door shut, revealing him ......
