As soon as class was over the next day, Darren went to Ron's twin brothers, Fred and George, to help him build a Muggle system that had been used in every village fifty years earlier, the broadcasting system. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

The reason why I looked for them was because Darren knew that this pair of living treasures was definitely a high-achieving student who linked theory to practice, and his hands-on ability was first-class, which was known by looking at the magic props they made later, and they were the best partners to engage in entities.

What's more, they just had a suitable toy in their hands, although they may not have finished it now, but in the future, they just let them advance a little, of course, they also need to improve a little, this toy is, the telescopic ear, the tool that Fred and George will use to eavesdrop on the conversation of the Order of the Phoenix in the future.

Although Darren doesn't know if there is anything like cable broadcasting in the wizarding world, it is obvious that Hogwarts does not have it at the moment, so it is absolutely just needed, it is just whose equipment is used, and now his own students have a similar project at hand, which can solve practical problems, and allow students to practice by the way, so the fool will not agree.

Moreover, this time Darren bumped into the troll is definitely a disaster for the pond fish, what Snape said last night was right, it was indeed bad luck, but it was also partly because the speed of information transmission in Hogwarts Castle was too problematic, and the restaurant was in a mess, and Darren and Hermione, who were not in the restaurant, were completely unaware, fortunately this was a troll, if there was any other opponent with a little brain, I am afraid that Hogwarts would have to suffer heavy casualties.

So after Darren came back, he learned from the pain and decided to take this opportunity to quickly upgrade Hogwarts to avoid similar situations, and Hogwarts would not have to deal with trolls in the future.

Of course, Darren also has his own selfishness in doing this, that is, he has to find a way to start making money, he is not a rich second generation like Harry, nor does he have a middle-class father and mother like Hermione, even Ron is better than him, although the Weasley family has always been known for having no money, but the family has a strong connection, not to mention distant relatives, Ron alone is a master who can toss, so he looks poor, but in fact, the real strength is like an iceberg, hidden below the surface of the water.

And when it comes to making money, what is more profitable than engaging in public works? What's more, through this project, Darren can also participate in Fred and George's inventions, those are all magical inventions, there are no two brushes, don't even want to make them, Fred and George's academic performance at Hogwarts is quite good, the most important thing is to have an innovative spirit, absolute talent!

When Darren met with Fred and George, the twins hit it off with Darren's idea and went to Professor McGonagall together, and Professor McGonagall, after hearing Darren's idea, also greatly appreciated and expressed her full support, and immediately auctioned 50 Galleons as a start-up fund.

Of course, although the principle of the broadcast system is very simple, it is absolutely difficult to do it in the castle of Hogwarts, because the structure here often changes, so some equipment must also have the corresponding adaptability, fortunately, Fred and George know a lot of secret passages and tricks, so it is also twice the result with half the effort, plus the strong adaptability provided by the telescopic ear, the whole project is going well, in addition to going to Professor McGonagall from time to time to ask for funds, is waiting for the test after the project is completed, and the award.

According to Professor McGonagall, when the whole system is completely completed and working normally, even if they don't get the "Special Contribution Award to the School", there is no problem in getting a "model student", in that case, the three of them can add at least thirty points to Gryffindor!

For Darren, the biggest takeaway from this process is naturally not Galleons and rewards, but the magical knowledge learned from Fred and George, and the twins are definitely worthy of the words "mentors and friends".

Although throughout the project, in addition to the initial concept, Darren is completely a soy sauce character in the specific work, and always asks questions, but both Fred and George did not have the slightest dismissiveness, but patiently answered Darren's questions, of course, they also enjoyed it, after all, the communication between smart people is always pleasant.

In Darren's opinion, during this time, he gained more magical knowledge than he had in a few months after entering Hogwarts, of course, without the previous study, he could not understand the twins' explanations at all, and in turn, the twins further stimulated Darren's curiosity, so in addition to classes, he either worked with Fred and George, or studied with Hermione in the library, and was the last to return to bed every day, even the weather kept cooling, he didn't notice.

It wasn't until this morning, when Fred and George told Darren that they were going to play Quidditch tomorrow, so they planned to take a break from their work and relax, that he found out that the next day was Quidditch, and it was also the day Harry participated in Quidditch for the first time!

Darren suddenly realized, no wonder Hermione would be looking for Quidditch books in the library in the last few days, she would never read anything unrelated to study before, she should have found it for Harry. During this period of time, all his energy has been devoted to the campus radio system, and he has not noticed anything else at all, perhaps this state of work is also an ability of his.

During recess, Darren followed Harry and the others to the courtyard outside, only to find that the weather was already so cold, the mountains around the school were covered with ice and snow, and the lake around the school was also frozen.

Harry was so surprised that they didn't know what to say, and finally Ron asked him how long it had been since he had walked around the castle, and Darren replied that it had been Halloween......

Because it was too cold, Hermione used her magic to conjure a handful of bright blue flames and put them in the jam jar to warm their hands, while Darren used the spell he learned from the twins to turn the jar into a basin, and the flames burned in it, making them warm and comfortable, and agreed that the next time they went to Hagrid's, they would barbecue in the open space behind the cabin.

Darren recalls once seeing a method of grilling fish in Northern Europe, after the fresh fish is processed, it is directly nailed to the wooden board and roasted next to the fire, because the smell of wood will sink into the fish, so there is no need for seasoning, just a little salt, and the taste is very delicious, you can try it when the time comes, there are all kinds of trees in the Forbidden Forest.
