"Tell me, Kreacher!" Sirius clenched his fists and roared, "how the hell is it going to get through here." ”

"Need blood, young master!" Kreacher said intermittently, pointing to a large smooth rock in front of Dumbledore, and in a crying voice, "Kreacher saw the Dark Lord spill blood on that rock, and Master Regulus did the same at the time, he cut his arm open, and"

Sirius was stunned for a moment, not seeming to understand exactly what Kreacher meant.

Behind him, Harry and Hermione looked at the rock in horror with uneasy expressions on their faces, as if something was about to crawl out of it. When they heard Kreacher mention blood, they couldn't help but think of a lot of terrible things.

Unlike them, Evan took two steps forward.

He stood behind Dumbledore, taking a closer look at the rock that Kreacher was pointing to.

In fact, from the moment he entered the cave, he felt a slight difference in the location, even though the rock looked indistinguishable from the surrounding rock faces.

However, Evan could sense that something was wrong. It was a strange feeling, he didn't know how to describe it, not in the senses such as sight and touch, but in the magic there was more abnormal than the magic reaction in other places.

It's like a normal light that suddenly disconnects at a certain point.

"All magic leaves a mark, you have to feel it with your heart!" Dumbledore whispered, taking a few steps back and looking at Evan with understanding.

"Mind to sense?!" Evan didn't know what to do.

He just instinctively felt that there was something abnormal about the magic reaction on the rock in front of him, but he couldn't say where the specific anomaly was.

Dumbledore didn't continue, pointing his wand at the rock in front of him.

Suddenly, the outline of an arch appeared there, radiating a dazzling white light, as if there was a strong light shining behind the crack.

"You've succeeded, Professor!" Harry cried out in delight.

He had just been disturbed by Kreacher's words, and a glimmer of hope rose up at once.

With Dumbledore here, they didn't want to spill blood on that rock at all, and they could pass through here.

But before he could finish his words, the outline was gone, and the rock was as hard and thick as before, and there was nothing on it.

"Professor?"

"Kreacher is right, it does take blood to get through here. Dumbledore looked at it and said calmly, "He thinks he's successful, but he's too low!"

"I don't understand, why do we need blood to get through here?" Harry said confusedly, "And what do you mean it's too low?"

"To be precise, Riddle's magic requires us to pay a price, and we have to weaken ourselves to get through here, so that's why I say it's too low!"

Dumbledore's tone was one of contempt, even disappointment, as if Voldemort had failed to live up to his expectations, "Once again, he failed to understand that there were many things that were much more terrible than physical injuries." ”

"But you can avoid it"

"Sometimes it's unavoidable, and we have to deal with it according to the rules of magic. ”

Dumbledore said, shaking the sleeves of his robes upwards, and suddenly a short silver knife appeared in his hand, the kind used to cut potion materials.

"Don't, Professor!"

Seeing Dumbledore raise his dagger, Aven, Harry, and Hermione rushed to stop it.

Everyone knew what Dumbledore was trying to do, but they didn't know what to say, and if they had to bleed, they should choose one of them instead of letting Dumbledore do it.

"Let me come, I can," Harry said scrimbly.

But someone was faster than him, and just as they could stop Dumbledore, Sirius had already made up his mind, and he quickly rushed to the rock, and a flash of light flashed at the end of his wand, and his arm erupted a stream of crimson, and the surface of the rock was suddenly sprinkled with shiny, dark red blood beads.

"Sirius!" Harry turned his head slowly, looking at all this in disbelief, his face instantly turned pale, and he rushed to Sirius's side in a panic.

Dumbledore, Aven, and Hermione also hurried to follow, and they saw that Sirius's arm was a large wound, and a large amount of blood was gushing out uncontrollably.

"You should let me do it, Sirius, your blood is worth more than mine. ”

Dumbledore slashed the tip of his wand through the deep cut on Sirius's arm, and the wound healed instantly.

"No, it's up to me, it's for Regulus," Sirius replied weakly, looking up, "don't worry about me, I'm fine, is this blood enough? ”

"I'm sure that's enough!" Dumbledore said softly as he looked at the changing walls, "the effect is very noticeable. ”

The outline of the dazzling white arch appeared on the cave wall again, and this time it did not disappear.

The blood-splattered rock in the arch suddenly vanished, revealing a doorway that seemed to be endless darkness inside.

"Let's go in, you'd better follow me and get your wand out!" Dumbledore said, walking through the doorway.

Sirius, Aven, Harry, Hermione, and Kreacher followed him in, hurriedly lighting their wands.

In front of their eyes, it was a very strange sight.

Although I had heard Kreacher tell it before, the real scene I saw with my own eyes was much more shocking than all words and imaginations.

At this moment, they were standing on the shore of a large black lake.

The lake is so wide that you can't even see the opposite shore in the distance.

The cave they were in was so high that they couldn't see the roof of it when they looked up.

In the distance, as if in the middle of the lake, a hazy, green light flickered, reflecting in the dead water below.

Except for the green light and the bright light emitted by the five wands, there was a completely dense darkness that could not be dissolved, and the penetration of these bright lights was not as strong as expected, and the darkness here seemed to be denser and thicker than the ordinary ones.

It's hard to imagine that they are in a cave inside the cliff.

Through that arch, Evan thought they had come to another dimension, and he didn't know how Voldemort did it in the first place. He couldn't imagine what it would take to transform an ordinary cave into what it looked like.

"Kreacher, the corpse of Regulus," Sirius said suddenly, his voice sounding strange, not the usual shouting, on the contrary, there was a hint of irrepressible sadness in his voice, "Tell me, where is his body?"

"There's an island in the middle of the lake, young master!" he choked as tears flowed uncontrollably from Kreacher's big eyes, "Kreacher was there at the time, and saw Master Regulus being dragged into the lake by the hands of those dead men. (To be continued.) )
