Zhang Hao had already said the origin of the basilisk, so the others were nodding their heads as Hermione spoke, they didn't want Professor McGonagall to think they didn't know anything about it.

However, Professor McGonagall seems to disagree with the origin of the basilisk.

"My silly children, in fact the conditions for the birth of the basilisk are even harsher. She said with a grim face, "To be exact, the egg that hatched the basilisk was originally a demon egg. It was produced by a seven-year-old rooster when Sirius was in the sky, otherwise how could the basilisk have such a powerful magic? To kill the basilisk, one must find a rooster that hatches when Sirius is in the sky. Only its cry can kill the basilisk in an instant!"

It was the first time Zhang Hao had heard this statement, and the book did not record it in such detail at all.

Sure enough, the professors all hold secrets that no one knows.

"Professor, is there really no magic to deal with the basilisk?" Hermione was a little difficult to accept, in the little girl's mind, magic was almost omnipotent.

She had always thought that she couldn't cope with something because she didn't learn enough magic, and she didn't expect that there would be times when a knowledgeable professor couldn't solve something with magic.

"I'm afraid not...... At least I don't know of any magic against the basilisk. Professor McGonagall said worriedly, "I thought Hagrid would have a rooster that hatched in Sirius, but it doesn't matter if it's there or not. I'm going to have to get him some roosters and at least curb the basilisk activity first. ”

Zhang Hao was a little puzzled, did Professor McGonagall forget the Sword of Gryffindor, or didn't he know the Sword of Gryffindor at all?

The Sword of Gryffindor can also kill the basilisk!

The threat of the basilisk is too late, and it was just a fluke that no student died before, and who knows if something truly terrible will happen in the future?

"Even if magic doesn't work, isn't there any powerful weapon that can kill the basilisk?" Zhang Hao reminded, "I heard that Gryffindor House has a sword, can that sword kill the basilisk?"

Hope burned in everyone's hearts, especially Harry, Hermione, and Ron, who remembered that Gryffindor had such a treasure.

"The Sword of Gryffindor?" Professor McGonagall said, purssing her lips, "it may be able to kill the basilisk, but only those who truly possess the qualities of Gryffindor will be able to get it when they need it." ”

It was the first time Harry and the others had heard this, so they were a little confused for a while.

"But we need it now. Harry asked eagerly, "Didn't the sword be kept by Professor Dumbledore?"

"Who told you?" said Professor McGonagall, surprised, "The Sword of Gryffindor has been hidden at Hogwarts, but no one has been able to find it. This has been going on for a long time, and I've never heard Dumbledore say that the Sword of Gryffindor is in his hands. ”

Everyone was disappointed when they heard this, and the hope that they had finally found was gone!

Zhang Hao was suspicious: "Old Deng's scheming is too deep, did he get the sword of Gryffindor?"

"Perhaps, we can ask Professor Dumbledore. He guessed, "The headmaster probably didn't mention the Gryffindor Sword because he didn't need to use it." But now, we need the Sword of Gryffindor. ”

"You have a point, then go and ask!" Professor McGonagall thought about it for a moment, nodded and said, "It's not appropriate for so many people to go to him together, you and Harry come with me." ”

......

In the Headmaster's office at Hogwarts, Dumbledore was sitting at his desk writing something.

"Albus?" Professor McGonagall exclaimed softly, "our students have made a major discovery, about the recent attacks. There's a basilisk at Hogwarts - it's hidden in the secret room left behind by Slytherin. ”

Dumbledore was stunned for a moment, his face more serious than ever. He asked in a deep voice, "Really, you can speak slowly." ”

Professor McGonagall didn't speak, but looked at Zhang Hao and Harry encouragingly.

Zhang Hao deliberately downplayed the influence in front of Dumbledore, so he gave the opportunity to Harry.

Harry worked on and on, and after all, he finally made things clear.

"So, you want the Sword of Gryffindor?" Dumbledore whispered, "You want to use it against the basilisk?"

"Yes, Professor. Harry said firmly, "There's no time to find a rooster now, the Sword of Gryffindor is the only hope." ”

Zhang Hao wanted to speak and stopped, he said in his heart: "Where does this 'only hope' start?

Dumbledore didn't refute Harry's claims, he looked a little embarrassed.

"The only hope?" he said with emotion, "yes! Unfortunately, I can't summon the Sword of Gryffindor. ”

"How so?" said Harry excitedly, "You're the Headmaster of Hogwarts, and you're a former Gryffindor, so how could you not summon the Sword of Gryffindor?"

"What's so strange about that?" said Dumbledore casually, "It only comes when you need it most, and I don't need it right now." ”

Zhang Hao and Harry glanced at each other, both feeling a little helpless.

This old man's attitude is too calm!

It's about the basilisk and the safety of the students, can you be a little nervous?

"I know your thoughts, but I would advise you—" Dumbledore said kindly, "If there is a basilisk at Hogwarts, it must not be something you can deal with...... Not even the Sword of Gryffindor. So leave that alone, I'll ask Hagrid to buy some more cocks as soon as possible. Go about your business, don't wander the hallways, I don't want any of you to get hurt by the basilisk again. ”

In this way, Zhang Hao and Harry were kicked out of the principal's office.

The two were silent, and the atmosphere was a little better when they met their friends.

"How?" Hermione asked anxiously, "What did the professor say?"

"It's hard to understand that he wouldn't let us do this. Harry hung his head and said, "He's afraid we're in danger, but aren't we in danger if we don't deal with the basilisk?"

"It's not that the professors don't solve it, they just can't solve it for the time being. Zhang Hao said leisurely: "The easiest way to kill the basilisk - to find a rooster that hatches when Sirius is in the sky, aren't the professors working hard? Or do you want them to fight to the death with the basili......sk? The professors also have to fight the basilisk with their eyes closed. Can you imagine the danger?"

Everyone looked at each other and finally realized the crux of the matter.

Sometimes it is not difficult to win a war, but it is difficult to reduce casualties.

The professors had to consider more than just how to destroy the basilisk.
