Of course, not everyone is so weak, for example, Harry often spends his days outdoors in cold weather, rain or shine......

Apparently, Oliver Wood's Seven Wheels 2001 had greatly irritated Oliver Wood, who spent almost all of his free time training in Quidditch, so much so that both Fred and George complained to Darren that they simply didn't have time to study the "Living Point Map" and made no progress.

And Darren also gained very little, although he managed to enter several secret passages, but he was disappointed, because these secret passages looked really secret passages, not at all as complicated as the secret room used by Slytherin to hide the basilisk, it was completely built with magic, at least after a holiday of civil engineering, Darren was able to distinguish the traces of Transfiguration, small wavy ripples on the rocks, which were created by the fluctuations of magic when the soil was transformed.

However, although there are no clues in the secret passage itself, Darren found some fragments and small things in the secret passage, which should have been left by people who had operated in the secret passage, and through the magic judgment of Fred or George, it is believed that these things are about hundreds of years old, which proves Darren's conjecture from another aspect, that is, these secret passages were built between the Slytherin Chamber and the secret passage of the pig's head bar.

"What, interested in this spell?" Fred said with a smile as he stared intently at the way they cast their magic.

"Well, this spell is so handy that you can know when the item was made at once. Darren admitted without hesitation, this spell is simply a "leak" weapon, learn this, it is not unfavorable in the Pan homeland, if you really can't beat Voldemort, it's not bad to go to the big TC to be a foreign "touch gold captain", at least you have a magic wand in hand, don't be afraid of zombies or anything!

"Actually, it's not as convenient as you think, this spell is very restrictive," George said, wiping his hair, as both he and Fred had just returned from Quidditch Training, even though it was still raining bullets outside.

"This was researched by Dad when he was at home, and he was going to use it to determine when those magical items were made, you know, he worked in the Department of Magic for the Prohibition of Muggle Objects, where it was sometimes necessary to determine when the item was enchanted, and it turned out that the magic on the item that was released would conflict with the spell, and when the spell was used, either the spell was invalid, or the item 'boomed'. George made a gesture with his hands in a circle, then abruptly parted.

"But when Dad was studying the charm, we learned it and thought it was an explosive charm, but it turned out that at Hogwarts, the spell worked quite normally, but it was also limited to non-magical items. ”

"I think it's the magic of Hogwarts that works on these things, and it just works to get the spell to work. At that moment, Hermione suddenly interjected.

"The magic of Hogwarts?"

"Yes, it is recorded in "Hogwarts, a School History" that Hogwarts has been established for a thousand years, during which it has experienced many rests, renovations, and even serious damage, the wizarding world back then was not as peaceful as it is now, and the dark magicians were much more powerful, so many headmasters would put various protective charms on Hogwarts, many of which are still in operation today, for example, Hogwarts is one of the few places in the United Kingdom where you can't use "Phantom Transfer" and "Apparition Manifestation", which has a large area' Muggle banishment' spells, and so on. It can be said that Hogwarts is one of the places with the highest magic in the whole of Britain. ”

Hearing Hermione's words, Darren suddenly felt that he had grasped something, but he didn't know what it was, and he couldn't help but ponder.

In comparison, Hermione has gained the most, and with her extraordinary memory, she specializes in "living point maps" The patterns and streamers shown on the show were searched, and the results were searched through the common sense area of life in the library, from which the approximate time period was determined, although there is no so-called fashion in the wizarding world, but the magic spell and writing style still have the characteristics of the times, people will always like new things, wizards are no exception, the old style will be slowly forgotten, until it is almost extinct, and then turned out by the new and new humans who are unconventional as new targets......

"So, the 'Living Spot Map' is about the product of the nineteenth century, a hundred years ago, and of course it may be a little newer, but it will not be more than 1850 at the earliest. Hermione confidently said to Darren and the twins.

"Why are you so sure it won't be earlier than 1850?"

"Because before 1850, there had never been any lace and ornamentation next to the 'Living Point Map' in literature, and then it began to appear in all kinds of books, and until now, there are some antique books that have them, such as Lockhart's work. ”

"Alright, so we'll study magic after 1850," George said happily.

"If Oliver gives us free time," Fred added, and both of them hung their heads.

"Or is it because of Slytherin?" Darren asked, knowingly.

"Yes," said George, "those new broomsticks, the Halo 2001 is very fast, and the Slytherin players riding on it are now just seven faint pale green shadows, and we can't fight them at all, after all, the performance gap between brooms is too great." ”

"Probably Slytherin will win the House Cup this year, Ravenclaw and Hufflepuff are no different, their broomsticks are similar to ours. Fred added, listening to his tone, even if the other two houses won the House Cup, it would be better than Slytherin, who made the lion and the snake already a mortal enemy, like fire and water.

"Oliver looked at several tactics, but we all thought it didn't work because the difference in speed was so big that we couldn't catch up or avoid the Slytherin guys, we were always intercepted or thrown away. ”

"Didn't you look at the previous history and see if there were any teams that had the same problem and how they solved it?"

"To make matters worse, according to Oliver's account, in a Quidditch World Cup match in 1473, one of the players suddenly changed to a new broom before the game, gaining an overwhelming advantage in the performance of the broomstick, and as a result, there were 700 fouls in that match......!

"Moreover, the other side still lost, but they managed to delay the game for two weeks in order to come up with a new way to foul them. ”
