In order to consolidate her strength, Catherine, with Snape's permission, created a combat training room under his potions material warehouse. To Snape's surprise, however, it took Catherine a week to get the groundwork done, and the props she had scavenged in the Americas had yet to be placed.

Since Snape also had a lot of potions to sort out, it wasn't until he had time to check it out that he realized why Catherine had spent so much time, because she had almost turned the entire 200-foot underground around 17 Spider's Tail Alley into a large labyrinth, simply because she didn't want a potential intruder to enter 17 Spider's Tail Alley from underground.

After studying the three-dimensional map of the underground labyrinth, Snape also put forward his opinion, and the two discussed it for three days before finalizing the final layout, and then it took more than a week to complete the general layout.

But what the two of them didn't expect was that in the more than half a month that they had almost turned a deaf ear to what was going on outside the window, a "conspiracy" had already started around them.

The "conspiracy" was caused by Harry's complaints about the lack of an address book and the inconvenience of connecting Ron and Hermione, the inability of the three of them to communicate at the same time, and Ron's constant use of yelling when talking on the phone, etc., which Dobby copied to Catherine as it was.

Because Catherine borrowed the magic of Hogwarts itself to function when she designed the address book, she lost all functions as soon as she left Hogwarts, so she took it back and upgraded it, but she didn't have time to transform it because of K's affairs.

So after hearing Harry's complaints, Catherine simply shrunk the simple radio wave transceiver system into it so that they could restore their communication function, and sent it directly to the three Gryffindors.

In order not to be scolded by Draco for favoritism, Catherine had to spend the night adding a function to the other address books that were resistant to magical interference radio waves, so that the three Slytherins could use them freely even at home.

But when the three Slytherins who received the "upgraded" address book half a day later opened it happily, they found that there were already thousands of messages in it, and when they looked closely, they found that all of them were Harry telling about his trip to the Americas, and he even had a lot of pictures attached to it.

Of course, Catherine has not yet added the function of sending photos to the address book, but relying on the direct input of the wand's consciousness, she can still draw the memories in her mind, although because of the solidity of the memory, it will deviate from the original scene, but Harry is practicing using the meditation basin to relive and summarize the harvest of the journey, and the picture drawn is naturally comparable to the scene.

This made the three Slytherins look very hot, especially after asking the elders in the family to confirm the prosperity of New York's Fifth Avenue, but because there were "seven orders everywhere, eight orders like lackeys, nine orders often seen, and ten orders are not a lot", so even Lucius was reluctant to bring Draco at the end of the seventh order, let alone Brayce and Pansy, the two sixth orders.

Harry was able to be safe and sound there because the four people around him were very strong: K was super sensitive, always able to detect anomalies at the first moment, and his identity was a little strange; Dobby seems unbearable, but he is a house-elf of free contract, which makes people completely confused about their strength; Catherine was only 13 years old when she reached the eighth order, and no one with a bit of brains wanted to offend this potential stock, and there were obviously no brainless people who could gain a foothold on Fifth Street; Snape was not easy to mess with at first glance, and he had personally experienced his mastery of potions, and this invisible and untouchable method was the most terrifying; Coupled with the jade pendant given by the turtle elder, so that everyone's attention was focused on Catherine, Harry would only be slightly harassed, otherwise he would be like an ordinary sixth-order outsider, his whereabouts are unknown or even his bones are gone.

This made the three Slytherins extremely depressed, they also wanted to enjoy the original scenery of South America, go to New York's Fifth Avenue adventure to treasure hunting, and go to Five Lakes Town to experience the hospitality of the water tribe, but they were not saviors, none of them traveled, and the treatment of four people was protected, but they were very unwilling to swallow this breath like this.

So the three Slytherins gathered at Malfoy Manor to discuss countermeasures, and finally they decided to make a trip that was not inferior to this, but the problem is that as a member of the upper class, they don't know how many trips to the country, how many places they have visited, how many famous attractions they have visited since they were young, and it is really difficult to find a place that has both primitive scenery, adventure and hospitable, and can also enjoy hospitality.

They flipped through the world map of the wizarding world several times, and finally pointed to Africa, which is definitely a feast for the eyes because of the natural landscapes that are not inferior to South America, the mysterious brilliance of the pyramids, and the exotic characteristics of the black witch people.

As a result, the three Slytherins began to "counterattack" in the address book, first belittling Harry's trip to the Americas, and then starting to talk about the benefits of Africa and discuss their itinerary exaggeratedly, which immediately provoked protests from the three Gryffindors.

Since Catherine designed this address book in the way the forum operates, as long as it develops, all holders can see it, so at first the three Gryffindors were still wondering why the Slytherins suddenly stopped speaking, how did they know that their "counterattack" would be so rapid, but although Gryffindor was caught off guard, they quickly reacted, and the two sides confronted each other on the address book.

Because you can type in immediately when you think of anything, the speed of the messages in the address book is, in Harry's words, more spectacular than the Nicaraguan Falls.

After arguing for more than a week, knowing that Ron had suddenly called Hermione and Harry to say that their family had won the Golden Galleon Award from the Daily Prophet, Arthur and Molly decided to travel to Egypt together with the family, and the time coincided with Draco's schedule.

Ron couldn't persuade his parents to change their minds, so he had to ask Hermione and Harry for help, he didn't want to fight three Slytherins in Africa alone, Hermione and Harry were soft-hearted by him, and the description of Africa by the three Slytherins also made them itch, and finally agreed.

Mr. and Mrs. Granger have only one daughter, and Hermione wants to change her route to Egypt, so they naturally have no opinion, anyway, they just accompany their daughter out to see; The Draco family was annoyed by what Harry had brought back, and when Harry was leaving, they almost raised their hands and feet in agreement, and Petunia even sponsored him a round-trip ticket.

On the other side, Gryffindor's dumb fire made the three Slytherins feel a little uneasy, but they discussed for a long time without the slightest clue, until the three Gryffindors broke the news that they were going to Egypt, especially after Weasley's family had gone, Slytherin instantly felt a dark cloud.

Thinking of the Weasley twins, who were comparable to the potion of chaos, the three Slytherins looked at each other and immediately made a decision - call someone!

Soon, all the third-year Slytherins except Catherine answered the call, along with Daphne's sister Astoria; After hearing the rapid increase in the number of people on the Slytherin side, Harry and Ron couldn't help but ask their roommates, but Dean and Seamus already had other arrangements, and in the end, only Neville agreed to go with them after getting his grandmother's consent, but after Ginny accidentally talked to Luna, Luna immediately said that she had always wanted to go to Egypt, and finally they even pulled Magan.

As a result, before the adults were aware of it, the number of underage wizards on this trip to Egypt had increased dramatically to 19, and the total number of adults reached 24, which made the SG team face a very serious question of whether to inform Catherine about the matter.

With the state of the SG group at this time, if Catherine had not been reconciled, the "war" would definitely break out the moment they met, and the adults might even be implicated in the end.

But Catherine hasn't said a word so far, obviously too busy to even open the address book, so informing her that she will definitely be scolded, but if she is not notified, the consequences will be even more severe, Catherine will definitely delay the punishment until after the start of school, and personally give them an unusually profound lesson in person.

So it was really just a choice between individual punishment and collective punishment, and the entire SG group eventually acquiesced to the latter option, because they were all at fault, so they all fell silent and waited for Catherine to find out for herself.

But until it was about to leave, Catherine still didn't make any move, and even Snape, who had always been the most disagreeable about it, didn't say anything, and the SG team was in a hurry, and they didn't care about the fact that the message would be seen by everyone, and openly discussed how to inform Catherine, and coincidentally, while they were discussing, a visitor came to 17 Spider's Tail Lane.

"Catherine! Severus! What the hell are you up to? I knocked on the door for nearly half an hour, and you didn't even hear it, and you had to set off the alarm before you came to open the door. A white-bearded old man, blinking his blue eyes, asked curiously about the two owners of 17 Spider Tail Alley.

"Albus Dumbledore! You'd better be justified! Otherwise, you don't want to have a sweet tooth this year! Snape shouted angrily that if Dumbledore had triggered the alarm for a second in the morning, the delicate trap he was laying would have fallen short.

"I just wanted to ask Catherine why my address book doesn't work?" Dumbledore's face was full of innocence, and of course he didn't bother to think of any other way to notify them to open the door.

"Sorry, Headmaster, I forgot to get it back for an upgrade." Catherine also had an innocent expression on her face, who called Dumbledore usually had little intersection with her activity trajectory, she naturally didn't bother to pay attention to the address book in his hand, not to mention that she was so busy that she didn't even deal with Snape's, only her own as a "terminal processor", and had to follow others to modify.

"How long will it take to get it right?" Dumbledore handed over his address book expectantly.
