Although Darren temporarily refused Hermione's request to order a wetsuit under the pretext that there was no time, this was only temporary, and without using spells and potions, it was better to expect Hermione to forget something, and it would be better to find a way to dry up the black lake......

However, in the face of Hermione's request to "increase practice opportunities", it is difficult for Darren to refuse, on the one hand, judging from the current situation, he really has no excuses, and he can't just say "This is dangerous, you are a girl, don't go", that will definitely be shot to death by Hermione!

On the other hand, although Darren was reluctant to let Hermione get involved in the battle with Voldemort in the future, it was only his fantasy in any way, and with what he knew about Hermione, unless she kept everything about Voldemort and the Horcruxes a complete secret, she would definitely follow her to "defeat" Voldemort as long as she had the slightest contact with the situation......

And think about the other two people around Hermione, Ron and Harry, and now Darren can see that they can be a riddle when they stand together, and the name of a cartoon is "brainless and unhappy". Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

With that brain, expect them to be able to control themselves and not mention Voldemort's affairs to Hermione, forget it, and in addition, add a Dumbledore...... To a certain extent, this is also the reason why Darren is desperately trying to improve his strength, that is, if he really gets to that point, even if he can't beat Voldemort, at least he can compete with the Death Eaters, no matter how bad he is, he has to be able to escape.

So, I'm afraid Hermione has to have enough strength to protect herself, thinking of this, so that Darren is also helpless, no way, "manpower is sometimes poor", compared to his wishes, the power he has is too weak, "do whatever you want, that's something that God can do", you know, even if it's just "don't do what you want", it is also regarded by Kant as a sign of "freedom", for the vast majority of people, it is still "what you can do", among them, naturally includes Darren……

Fortunately, going to the Black Lake to find Grindillo's bad luck, with Darren's current strength, it is not a dangerous thing, as he himself said, the last time he was injured was completely because he was too careless, if he brought Hermione, he would definitely be 120,000 careful, no matter what, he would not be attacked!

After much hesitation, Darren agreed to Hermione's request and asked Penelope to help order a wetsuit, and at the same time, as Lupin did last year, he used his spare time to guide her to practice the "Bubble Head Charm" and the "Fire Charm", both of which had proven to be very useful for underwater activities, and he didn't have to take the exam this year anyway, which in his opinion was one of the few treatments in the Triwizard Tournament that really appealed to him.

In addition to the "Bubble Head Spell" and the "Flame Spell", the most powerful "Impact Spell" underwater, the situation is a bit special, except that its lethality under the water is too great for him to control well, but also because the "Impact Spell" is still not completely completed!

Although, under Professor Flitwick's guidance, Darren is now able to cast the "Impact Charm" with a relatively fixed spell , but there are still many problems in the magic transformation and body sensing of casting spells, fundamentally speaking, many of them are specifically for him, or, just like the instinctive movements of the human body, after a long time of practicing casting spells, his body will automatically complete some of these steps in the process, and this habit is not the same for every wizard, so from a certain point of view, the "impact spell" is an exclusive spell for Darren.

Although this may sound cool, from the perspective of spellology, it can only be said that the "Impact Charm" is still an incomplete spell, in fact, except for Darren, there are only two ways for others to master the "Impact Charm", one is to generate a shockwave by creating a magical conflict at the beginning, which is dangerous and inefficient in mana transformation, and the other is to solidify a suitable "spell" for their own magic fluctuations and transformation methods under the guidance of a master like Professor Flitwick! Even Professor Flitwick is no exception to this, because he doesn't really understand the physics of shock waves.

Compared with the half-finished "impact spell", a truly complete spell should be like the spell recorded in the spell class textbook, any wizard who has magic power and knows how to cast a spell can cast it in the same way, by chanting the spell, which undoubtedly requires the person who created the spell to be very familiar with the magic transformation method of the spell, and can express it with the spell, and at the same time get rid of their own unconscious operation of the magic transformation process, making it a spell suitable for anyone to use.

Therefore, Professor Flitwick can only guide Darren to better complete the magic transformation, but he can't express it in spells, because he doesn't understand the principle of the generation and propagation of shockwaves, and although Darren knows the mystery, his magic theory is too poor to express it in the language of spells......

This shows how difficult it is to invent a spell, and only a generalist who understands the whole workings of the spell, actually operates it, and is familiar with the language of the spell can create a spell that can be cast by anyone who learns it!

Darren thinks that he will probably have to get together with Hermione, and then add at least half of the Hogwarts library to do that, but he doesn't plan to do magic research, so the "Impact Charm" can be used, and as for standardization, isn't Professor Flitwick researching......

Soon after, Hermione's wetsuit was ready, and Darren's new ones were also sent to Hogsmeade by Penelope, and Darren picked them up, but, at this time, a new question arose, how to wear them?

This time, because Darren ordered a large number of wetsuits, considering the season, in addition to the same dry wetsuit as last time, he also asked for a wetsuit, and Hermione was no exception, there were several sets of them.

The wet suit is relatively simple to wear, just a little explanation, but the dry suit is much more troublesome, and after Darren's practice, he has summed up some new tricks to improve the performance of the wetsuit and avoid water, some of the main points, just by lip service, Darren is not sure if Hermione can master it all, some things, after all, still have to "practice" it.
