"I have improved my evaluation of you as much as possible, but now I find that I have underestimated you, Silver 1ka," Dumbledore said in a deep voice, "Who is behind you? How could he know about this!"

"Who is behind me? There is no one behind me." Silver sneered. "The Silver family is one of the school managers of Hogwarts. Do you know a little bit about Hogwarts' secrets? Now is not the time to explore this issue. You'd better turn on Hogwarts' defense facilities as soon as possible. If you're a little late, there's no need to turn on it in the future."

"But the school director is not qualified to know this." Dumbledore spoke faster, "This is Hogwarts' biggest secret. Only the previous principals have the right to know and keep this secret. After learning this secret, the previous principals have made a vow that they will not mention this matter to anyone except to tell the successor. It is okay to open the defense facilities, but you must tell me who is behind you? Even your great-grandfather Richard doesn't know the secret about the Hogwarts defense facilities..."

"That's right! How could you know about this matter from the Silver family?" Phoenix Nigerus Black, who was hanging on the wall, looked very surprised. Yishu Shushu·The great-great-grandfather of Sirius Black, the most unpopular principal in Hogwarts' history, turned into a messenger of justice. "No one else knows this secret except the four founders and previous principals! Your question must be explained clearly!"

In an old portrait next to him, a yellow-faced witch with short black bangs said helplessly: "Phenias, don't be so loud, you are no longer the principal."

"Shut up! Ever!" Phineas Nigerus Black suddenly showed some inexplicable excitement, "I'm for Hogwarts!"

"For Hogwarts? I don't know that the most unpopular principal in Hogwarts history is such a principled wizard." Silver said, "but I think you will change your mind soon."

Xue Yuan took out a fake Gallon gold coin, and the number on it was changing slowly. "My companion told me that Sirius Black, the last direct successor of your Black family, has also come to Hogwarts, and is now fighting fiercely with the minions under the devil. The situation is not very good now. Do you really want to agree with Dumbledore and get involved in these details than considering your own descendants?"

"Sirius?! This damn kid actually came to such a place." Phineas Nigerus Black's face darkened in the portrait.

"So you should be on my side now. Do you care about where I know the news?" Silver said angrily.

Phineas suddenly stopped talking.

He said to Dumbledore, "You have your ideas, okay, I can not interfere. But even if you don't go to the battle, at least you can activate Hogwarts' defenses. Although you let Slughorn be the principal, you did not pass on the authority and this secret to him. Then it's time for you to use this authority. Dumbledore, please answer me! Do you want them all to die?"

"Can we win?" Ron didn't know whether he was talking to himself or asking someone else, but he used a spell to repel a vampire that rushed up.

"I don't know, child." Sirius was also panting. He stepped on two bats that were already dead.

The enemy surrounding Hogwarts took a second wave of offensive after casting spells and bombings from a long range. The vampires who transformed into bats caused them a lot of trouble - although the combat power of vampires was average, the number was too large.

Harry was about to speak, but when he was at his mouth, he suddenly felt a chill surge in his heart, fear grabbing his heart—

"Look down quickly!"

He had only had time to say this.

The air suddenly exploded and the world was torn apart. Harry felt that he had flown into the air, and he could only grab the thin wooden stick, his only weapon, and protect his head with his arms. He heard the shouts and screams of his companions, but could not know what was wrong with them-

Then the world gradually turned into pain and blur: half of his body was buried in ruins, and the corridor was just terrible attacked. The cold air told him that one side of the castle had been blown away, and the warm and sticky feeling on his cheeks told him that he was bleeding heavily.

Sirius and Ron struggled to stand up from the ruins, and the two stumbled past the gravel and the chips of wood to rescue Harry.

"Harry, are you okay?"

"I can't die." Harry finally breathed a sigh of relief when he saw the two of them.

"What was that just now?" Ron pulled the bricks that pressed Harry's body, and his whole body was trembling slightly.

"I think it was the devil who took action. I could never imagine such amazing magic in my dreams." Sirius smiled bitterly and pulled Harry out of the ruins with Ron.

"Can we still win?" Sirius looked a little confused. The unparalleled magic just now shattered Sirius's confidence.

"I believe we will win," Harry said.

At this time, Harry felt the entire ground shaking slightly.

"What is this? Is it the magic of the devil again?" Ron was a little panicked, because the vibration was getting bigger and bigger, and they were all a little unsteady.

Their enemy vampires were also in trouble at this time. The bats they turned into seemed to be attacked by invisible forces in the air. They suddenly stiffened their bodies and then fell directly to the ground.

"No, no, it's not that devil is messing around." Sirius's face suddenly became bloody. He rushed to a window that was only half blown away and looked down.

"We are flying! Hogwarts are flying!"
