Days to grind friendship at Hogwarts

Everyone climbed up the steps, and Dumbledore walked slowly to the center of the cave. He raised the hand holding the Elder Wand high and slowly turned in circles, carefully examining the rock walls and the cave ceiling.

After a moment, he said softly: "Yes, this is the place."

"How did you know?" Harry asked, confused.

Dumbledore smiled slightly and simply explained: "There are traces of magic being used here."

He continued to observe for a while, with deep blue eyes flashing from time to time.

After a moment, he spoke again: "This is the front hall. It can only be regarded as an entrance. We still need to go inside. What is blocking us now is no longer an obstacle set by nature, but a mechanism set up by Voldemort."

"I think you should have discovered something, Glenn?" He gently stroked the cold and damp wall and said again.

Glenn closed his eyes, but instead of seeing darkness, his eyes lit up, like a camera with thermal imaging mode turned on.

However, the different colors do not reflect a person's body temperature, but the intensity of the magic power in the body.

Not only was Dumbledore's red color obviously not of the same grade as theirs, but Qiu's red color was much darker than Harry's.

As for Glenn himself, although there is still a gap between him and Dumbledore, he is no longer as unreachable as before.

In addition to the four people, there was also a gray-black, cloud-like magic group concentrated on the wall in front of them, outlining the shape of a door frame.

"Here..." Glenn opened his eyes and pointed to where the door frame was.

Dumbledore leaned over, with a somewhat satisfied smile on his face.

"How did you do that?" Harry asked dumbfounded.

"Observe more, and you will slowly feel the changes in magic power." Glenn simply explained that he had a big plug-in called the system. No matter how talented Harry was, he would never be able to replicate such success. "My family has a book called

I can lend you the ancient book "The Source of Magic" to read when you get back."

"Thank you so much!" Harry nodded repeatedly, allowing him to spend another wave of favorability and exchange coins in vain, even though all of his spells had basically been upgraded to the master level.

Dumbledore, who was not far away, waved his wand, and the outline of the doorframe immediately appeared, but disappeared in the blink of an eye.

After he pondered for a few minutes, he smiled again.

"It seems that I still overestimated you, Tom. This is really low-level..." He whispered to himself.

"What did you say, Professor?" Harry asked again, not hearing clearly.

Dumbledore shook his head slightly and said: "It seems that Riddle has placed a restriction here, and we need to pay a price to pass."

"The price?" said Harry. "We have to give the door something?"

"Yes," Dumbledore nodded, "if I'm not mistaken, it's blood."

"Blood?"

"That's why I said, it's too vulgar." Dumbledore said, his tone full of contempt and even disappointment, "I believe you also understand this truth - only by weakening yourself can you move forward. It seems that Tom is again

For once I failed to understand that there are many things that are much more terrifying than physical harm."

"Yes, but you should have a way to avoid..."

Before he could finish speaking, Dumbledore shook his head again and said, "Sometimes it's unavoidable."

As he spoke, he took out a silver knife from his arms and pointed it at his left hand, which had recovered a lot.

"professor..."

Qiu tried to stop him, wanting to provide the blood needed to pass through the entrance on his behalf.

Dumbledore shook his head gently at her, and the knife slowly but surely slashed across his arm, blood gushing out and sprinkling on the rock surface.

The wound was deep and long, and Dumbledore lost more blood than Glenn imagined. Under the dim fluorescent light, his face was obviously pale.

If you think about it carefully, this makes sense. If only a small amount of blood is needed to open the entrance, it will not have the effect of weakening the entrants at all.

Glenn gently raised his hand, and several flashing fluorescent balls floated into the air.

Dumbledore looked at him slightly surprised, showing a bit of satisfaction.

Qiu also took out the wand, pointed the tip of the wand at the wound, and the silver light flashed, and the bloody and horrific wound healed as before in the blink of an eye.

At her level as a master therapist, this most basic wound treatment is as simple as eating and drinking.

Blood soaked into the rock wall, and an archway with dazzling white light emerged. The blood-stained stone in the door also disappeared, revealing the long and narrow corridor behind it.

The range of fluorescence illumination is limited, and only darkness can be seen at the end of the corridor.

"Thank you, Qiu, we can continue our journey." Dumbledore put down the sleeves of his robe and stepped into the arch first.

Several people followed immediately, and the fluorescent balls summoned by Glenn floated around them.

The scene at the end of the corridor is a bit strange.

They were still in the cave, with an endless black lake in front of them, and the other shore could not be seen at all in the darkness.

In the distance, as if in the center of the lake, there was a vague and strange green light, reflected in the dead lake below.

The darkness here seems denser and thicker than ordinary darkness, as if you are in a fog. Neither the tip of Dumbledore's staff nor the ball of light summoned by Glenn can completely penetrate this thick darkness.

Dumbledore lowered his head and looked at the faint lake water, and said: "You need to be careful here, don't touch the lake water."

The three of them nodded and followed him along the lake shore.

On one side is a rough rock wall, on the other side is a lake shining with black light, and in the center of the lake shines a mysterious green light. Except for the sound of footsteps, there is silence.

Such a mysterious and depressing atmosphere obviously made Harry feel uncomfortable. He hesitated for a long time, but couldn't help but said: "If the Horcrux is indeed here, Professor, can we try to use magic? I remember Glenn mentioned one

...Flying curse.”

At this time, Harry had not experienced the dragon battle in the Triwizard Tournament, and his understanding of the Flying Curse was only based on "hearing" about it.

"Of course," Dumbledore stopped, "it's worth a try."

Seeing his gaze, Glenn took out his wand and chanted a spell.

"The Horcrux is coming!"

With a loud bang like an explosion, a big white guy jumped up from the dark lake twenty feet away and headed towards the crowd.

Harry was obviously shocked. Although Qiu had been through a lot, she was still a girl, so she subconsciously took a few steps back.

The pale monster twisted in the air for half a second, then fell down again, breaking the calm water with a "plop".

The water splashed and rippled in circles.

"What is that?" Harry asked with lingering fear.

Glenn's eyes stayed at the center of the ripples, and he said slowly: "Inferi..."
