After Zhang Xu left the principal's office, he returned to the Muggle Studies professor's office, and then began to call people.

Aside from Harry's trio, there shouldn't be too many people tonight.

So after some consideration, Zhang Xu decided to bring Neville Longbottom and the Weasley twin brothers.

Neville's family had a feud with Voldemort, and Neville had changed a lot in the past two years, and the cowardly look he had in his first year had disappeared from him.

Not to mention the relationship between the twin brothers and Harry, who belonged to Harry's family of relatives.

After considering the comprehensive strength, these three are the best candidates at present.

Ten minutes later, all six people who were called by Zhang Xu arrived.

"Professor Dumbledore has an action tonight, and he needs everyone's help." Zhang Xu said to Harry and the other six people sitting in front of him, "The professor needs to leave Hogwarts to find the items left behind by a mysterious person. There may be unexpected events in the process that he can't spare to solve, and that's when he needs our help. ”

"During the time that Professor Dumbledore was away, the other professors of the school had to patrol the castle just in case, so the other professors couldn't help."

"There is a certain danger in this matter, so it is up to you to decide whether to participate or not."

It's impossible to refuse, it's impossible to refuse such an interesting thing, it's impossible to refuse in this life!

Gryffindor is fearless!

Looking at the six little lions in front of him who were nodding vigorously in a flickered manner, Zhang Xu was ready to continue to tell them about the precautions.

Just then, the door to the office was opened, and Fleur and Scarlet walked in.

"What's the matter?" Zhang Xu asked.

"I'll go with you too." Furong said to Zhang Xu.

The corners of Zhang Xu's mouth twitched, it seemed that when he sent a message to Hermione just now, Fleur and Scarlet were with Hermione, and then the two of them came over to watch the fun.

When they saw more and more people coming into the office, they knew something was going on tonight.

If Scarlett wanted to eavesdrop, the office door wouldn't be able to stop her.

So when the two of them knew what was going on, they pushed the door in.

"We're not going on a trip this time," Zhang Xu said to Fleur, "and there's likely to be a fight tonight." ”

"I'm not afraid of any fight." Fleur said.

"This is a war against the mysterious people, and this is not a war for you." Zhang Xu shook his head and said.

"No, dear, this is our war." Fleur walked up to Zhang Xu's side, held his hand and said, "Now I'm not saying such things as a student of Beauxbatons, but as your lover, I will advance and retreat with you." ”

At this time, Zhang Xu's heart was very moved, what could be more satisfying than having such a life partner?

Then......

"Ahem!"

At that moment, Scarlet coughed twice next to them, alerting them that there were other people around.

"As long as Professor Dumbledore agrees, then you can go along." Zhang Xu said to Furong.

"So are you." Zhang Xu said to Scarlet on the side.

After telling everyone about some precautions for tonight's action, Zhang Xu waved his wand, and bowls of fragrant beef noodles appeared on the coffee table in front of everyone.

"Let's have a supper first, and then we'll be in Professor Dumbledore's office." Zhang Xu said.

After everyone finished supper, the appointed time was just up.

When Zhang Xu led everyone to Dumbledore's office, he happened to meet Snape and Lupin walking out of the office.

Snape gave Harry a hard look before leaving.

Everyone was surprised to see Lupin, and Harry tried to greet him, but Lupin smiled and shook his head before leaving.

In the Headmaster's office, Dumbledore looked at the row of people in front of him and nodded in agreement.

"I am taking you on one condition: you must obey any of my orders at once, without question." Dumbledore said solemnly.

A line of people nodded in agreement.

"If I tell you to hide, or to escape, you have to do it, can you do it?" Dumbledore said again.

A line of people continued to nod in agreement.

"If something happens to me, then you will all obey Mr. Zhang's command."

A row of people nodded in agreement.

After Dumbledore had said a few more words, they all left the Headmaster's office together.

At Dumbledore's signal, Zhang Xu cast a disillusionment spell on several other people.

"Very good illusion spell." Dumbledore said to the empty space on his right.

"The Invisibility Book of Invisibility is a good book," said Zhang Xu, who was standing on Dumbledore's right hand and had already turned on invisibility, "The book explains invisibility very thoroughly, and there are a lot of practical tips, I suggest that the school library buy a few copies back." ”

"I think Mrs. Pince will be distressed by this." Dumbledore said with a smile.

"As long as you are proficient in the Flying Spell." Zhang Xu also said with a smile.

The group left Hogwarts and headed for Hogsmeade.

After showing his face in front of the proprietress of the Three Broomsticks, Dumbledore first took the apparition-shifting Scarlet and Fleur to find his way, and then returned to take the others away.

There was no moonlight tonight, and on the seashore without light pollution, looking up at the stars.

On a huge rock, surrounded by rolling waves, Dumbledore tells the story of Voldemort's visit as a young man.

After the story was told, before leaving for the cave, Zhang Xu handed out equipment to everyone.

"This is the Iron Armor Charm amulet, everyone brings five, and there is no need to save if necessary. Professor, would you like to have a few too? Zhang Xu handed a few talismans to Dumbledore.

"Thank you, it's not too much to prepare." Dumbledore said after taking the amulet.

"You're welcome, I'll get the bill to the principal's office tomorrow." Zhang Xu said with a smile.

"We've got a long way to go, and we're probably going to have to wet everyone's robes." Dumbledore said.

"Then we'll just fly over." After Zhang Xu finished speaking, he took out a flying sword and four flying broomsticks.

"You're so well prepared, Zhang." Dumbledore said to Zhang Xu, "You really have everything in your bag. ”

"Just be prepared." Zhang Xu said with a smile.

Next, Dumbledore and Harry shared a broomstick, Ron and Neville, Scarlett and Hermione, and the twin brothers flew in front of them on broomsticks, and Zhang Xu followed Dumbledore with Fleur with his flying sword.

Everyone arrived at the cave without danger along the way, and the people who saw Zhang Xu's flying sword for the first time watched the flying sword for a while, and after Zhang Xu promised to lend them the flying sword to play after going back, everyone began to make the final preparations for the cave adventure.
