In fact, as Black and White expected, after returning from Hogsmeade Village, the mood of the mischievous trio was not high. Harry, in particular, had something called hatred in his eyes. This kind of black and white look has been seen in the eyes of many quest NPCs.

"You think there will be anything wrong with this plot, after all, there are still a dozen players in this Hogwarts! And who knows if there will be any players out there who will do something that affects Hogwarts. Gao Wu scratched the door frame with her cat's paws, and the snow on the ground made her a little uncomfortable.

Black and White looked upstairs at the trio with his hands on his chest, and said indifferently, "Like Hawkins said, they really seem to be here to learn magic, at least until now I haven't seen them behave out of the ordinary, and I haven't even had very little contact with Harry." ”

"Huh, how do you know?" Gao Wu's cat face was surprised.

Black and white pouted, "I inquired when I was helping Ron with his homework." ”

"You've done this before, he looks like a third-grade homework, you know?" Gao Wu's face was not very good-looking.

Black and white grabbed it and hugged it in his arms, "If your sister told you about it, you should know that my academic performance in reality is not bad, and I am even shocked by my talent for knowledge in magic." Of course, I must admit that it was difficult to give Ron an homework because he was so poor and I had to use some very childish vocabulary with a lot of holes!"

Gao Wu was unhappy, feeling that he was being shown off by Xueba.

At that moment, Harry reached out and punched the wall, then screamed and jumped to his feet. Black and White almost laughed when he saw this, and walked downstairs step by step, seeing Hermione from a distance as if she was going to treat Harry, but was stopped by Black and White's voice.

"If I were you, don't use spells!"

The trio was stunned for a moment, then smiled at Black and White a little secretly, and Black and White continued: "Although the spell can be called omnipotent, it is not out of nowhere! The healing spell you cast is used for emergencies, although it can make the wound heal quickly, but it consumes the mana in Harry's body, and once this mana is consumed, it will absorb the energy in Harry's body, which will make him feel very hungry." If you don't replenish your food quickly, you'll feel hungry, but it takes time to digest things, so it will also quickly burn off the fat in Harry's body. And we know that overeating hurts the body. It also makes Harry's routine irregular, and it takes a long time to recover. ”

Hermione looked at her wand and didn't know whether to believe him or not, it stands to reason that she is in the third year where the first year can be taught, but the speech is in black and white, you must know that the reputation of black and white is now a top student in the house, and the score given to Slytherin in the class alone is more than one hundred and fifty points! It can be said that unless Harry can lead Slytherin House by two hundred points in the Quidditch Cup, the final House Cup must be in Slytherin's bag.

"Oh, you're saying this spell can lose weight?" Ron's eyes flickered slightly.

Hei Bai's mind suddenly recalled the child's obese appearance in the later stage of the film and television version of the original book, and he almost burst out laughing, and could only say: "In fact, some weight loss spells and curses are developed according to this principle." But I'm not a professional, so I can't give you professional advice. Just like this healing spell, a real doctor can adjust his mana according to the condition, so I suggest you go to the infirmary and find Madam Pomfrey, she shouldn't have the leisure to care about how you hurt yourself or what hurt you. ”

Harry opened his mouth, looked at his stabbing fist and sighed, "Well, thank you!" and walked towards the infirmary with his head down.

Ron and Hermione wanted to follow but let Black and White stop them for some reason, seeing Harry walking away, Black and White suddenly looked back at the two, "Did you have blood on your hands?"

The two of them were stunned for a moment, looking at black and white in some surprise, and the wizard's intuition suddenly made them feel that black and white were a little dangerous. Hei Bai laughed secretly in his heart, in the end, he was a child, and he should be very easy to fool.

"I've had blood, and more than once! So I know what the emotion is in Harry's eyes, and I don't know what he's been through, but trust me. With your current abilities and awareness, I am afraid that even if you have the opportunity to kill, it is very likely that you will mess up. At least, in my opinion, you don't fight!" black and white hands in the cuffs, slightly turned his head with a serious and solemn expression, and then turned his head towards the other half of the corridor, "If you really have any trouble, you can come to me." At least, I have more say than you when it comes to fighting!"

Black and white left, leaving only two fooled children in a messy mess.

Ron: "Do you think he's telling the truth?"

Hermione: "Do you mean the healing or the killing?"

"Of course it's the killing part!" Ron looked confused, at this time, you can still notice the healing part?

Hermione rolled her eyes and looked at Ron with a look of hatred, "When he was in school, he killed a lot of Dementors with a pistol, is it surprising that he said he had killed people?"

Ron was shocked, "Is that part of the healing technique worth studying?"

"Of course, he said that he had developed a weight loss spell based on the principle of healing, isn't that worth paying attention to?"

Hermione's reasonableness made Ron feel like he couldn't understand the world again.

......

"Are they coming back for you?" Gao Wu asked, following Black and White's feet.

Black and White laughed, "They may not, but Harry will!"

"Why?"

"Because Harry already knew Sirius Black had betrayed his parents, he was murderous. But Professor Lupin can teach him the Patronus Charm, but he will never teach him a spell that takes a person's life!, so is there anyone else in the academy who can teach him how to fight?"

It's a pity that the person who slapped his face came at dinner, "Black and white, excuse me, you once said about weight loss spells before......"

Black & White: "......"

Two more days had passed, and Harry's patience was much better than he had expected. Unable to get an attack spell from Lupin, he endured it for two days before coming to him.

Late at night, forbidden book area.

Hei Bai waved the note in his hand with a little crying and laughing, "Actually, I don't care too much about the identity of a Slytherin student, you don't have to sneak a note to me, let alone make an appointment to meet here." ”

Harry shrugged his shoulders and found a corner of parchment from the corner of his robe, this thing must be a living map, maybe it was this thing that gave Harry the confidence that he would not be caught!

Black and White shook his head amusedly, "Is there anything you asked me out about?"

Harry seemed a little hesitant, but finally looked up and said, "Ron said, can you help me in the fight?"

The black and white eyebrows were raised, and then he nodded as a matter of course, with Hermione's personality, he would not tell Harry this, but Ron was very reckless.

"I see, well, then if you want to learn to fight, you always need to find a place where you can practice!" said Black and White Booth with a smile.

Harry turned around and said, "I've thought of this. Then he took Black and White and walked deeper into the hallway.

Hei Bai went up and held him down, crying and laughing: "You don't want to take me to the Room of Requirement, do you?"

Harry took it for granted that "isn't that the best place to practice?"

Hei Bai sighed, a child is a child! He asked with a serious face, "Have you ever expressed to the professors that you want to learn to fight?"

Harry nodded helplessly, "But the professors won't teach me." ”

Heibai said again: "Then why don't you teach yourself some black magic?" Stretching out his hand, "There should be a lot of them in the forbidden book area!"

Harry looked at the forbidden book section with some embarrassment, and then reluctantly, "Do you think I haven't tried......?"

"But the spell in the forbidden book area has changed, you can't get in, right?" Black and White said funny, since he had a magical bloodline, he was now very sensitive to magic fluctuations. Just like Professor Snape didn't know what spells were on the Living Map, but he was still sure there were spells on it, because he could sense the magic fluctuations on the Living Map.

Black and white noticed it after entering the library, and the magic at the door of the forbidden book area was only an alarm in the past, but now the function of prohibiting entry has been added. It must have been Lupin who had told Dumbledore about Harry, and Dumbledore obviously didn't want him to lay out the pieces too much beyond his control.

In fact, anyone who has read the original book, whether it is a book fan or a movie fan, knows one thing, that is, Dumbledore had already used Harry Potter as a pawn when he knew about the Horcrux, a pawn that must be discarded when necessary, because part of Voldemort's remnant soul is in Harry's body, and if he does not die, Voldemort will never die!

Well, that doesn't sound like a bad thing, and if a black and white nemesis leaves some of his remnants with him, he'll die happy. What a wholesome activity it is to get up every day and whip the remnant soul and then perform the torture that can be thought of on it in the morning, noon and evening!

Of course, in order to do this, one must have some research into the magic that works on the soul, and this magic is ninety percent of the black magic. Maybe Dumbledore was afraid that Harry would become a Dark Lord, so he chose this method once and for all.

Well, in fact, if you think about it this way, Harry has been in hardship since he was a child, his parents died and he was abused, and his only relative godfather died tragically in front of him when he grew up. The worst thing is because Harry's magical talent is not bad, if he still has power after blackening, do you say it's terrible?

So under this kind of intentional "protection", Harry Potter will not use a few powerful attack spells even after the end of the plot, and even use a weapon to remove you when he confronts Voldemort in the end! Hehe, what a classic spell! Fortunately, Voldemort was finally pitted by the old wand in his hand, otherwise it would be interesting if he took out a troll or dart out of his robe or a throwing knife!

Another explanation, of course, is that Harry knew but didn't. If this is true, then Black and White doesn't want to waste time teaching him. If you don't kill you anyway, why do you still learn attack spells?

"What does that mean? It means that your matter has caught the attention of the professors. And the Room is an almost open secret to professors and upperclassmen, so wouldn't the professors have imagined that you were practicing in it?"

Harry froze, "That makes sense, but we should ......"

Hei Bai smiled: "What you need now is to go back to sleep, don't let anyone see the flaws, and then come to me tomorrow at lunchtime." ”

"Why not breakfast?"

"I don't have class tomorrow morning, I have to sleep in!"

The next day, Harry came over to Black and White while he was having lunch, and naturally Ron and Hermione were also there, which was completely expected by Black and White.

"You're here to learn to fight, you don't need to bring pets!" Black and White glanced at the mouse in Ron's arms, a little irritated, it's not that he hates this product, but the value of this product is only funny at present.

Ron turned his head to look at Hermione angrily, and accused him almost in an accusatory tone, "If I don't take Spotted with me, he'll be eaten by that stupid cat!"

Hermione glared back, "Crookshank wouldn't do that, it must have been your spots that provoked him!"

Black and white rubbed his temples and interrupted: "According to scientific research, the reason why cats eat mice is because cats can't synthesize taurine in their bodies, and if cats don't supplement taurine, they will become blind." It just so happens that mice are rich in taurine, which is probably the meaning of natural enemies! However, the food of modern cats is very diverse, and it is also very rich and nutritious, so domestic cats are not short of taurine at all, and they no longer eat mice. After all, rats don't look as good as cat food, right?" he said, reaching out and touching Gao Wu next to him.

Gao Mai (='ェ ́=;) I don't eat rats again!

The three of them were stunned when they heard this, what should they say?

"You heard it, it must be your spotty!" Hermione snorted coldly, Ron didn't know what to say for a while, the pain of the scumbag!

Black and White sighed, "Well, Hermione go take Crook Hill and Ron will put Blob back in his bedroom." After all, if you practice magic, you can't limit Crook Mountain and Madara, but if it's just Crook Mountain, Xiao Wu will look at him. ”

Gao Wu stepped on the black and white fingers, and you are looking for trouble for me again.

Ron agreed when he heard it, and in their eyes, the black cat was almost the most obedient and powerful pet in the whole academy, which was confirmed after Gao Wu flew a dozen cats in heat.

But Ron obviously didn't see the banter in his black and white eyes, in fact, what Spotted was afraid of was not Crookshan, he was afraid of Sirius! And Sirius turned into a big dog at Hogwarts at this time, hehe, the opportunity is created for you, whether you can end the plot early, it depends on whether you can give it yourself.

The four of them, holding the two cats, slowly came to the vicinity of the beating willow, there was a passage to Sirius's hiding place, and once he noticed that the four of them were here, then he must have known that Spotted was now unprotected. Well, black and white in order to do everything without leakage can be regarded as a fight.

"Okay, it's good here, there is a beating willow here to suppress it, and no one usually comes. Black and white spread hands and made a joke.

However, the trio did not have this kind of awareness, and Harry looked at Black and White excitedly, "Let's start, what spell shall we learn first?"

Hei Bai said disdainfully: "First of all, you must understand what combat is! Fighting is not just about waving a wand and then chanting a spell, there must be an end first, and then a means! So what is your purpose? Kill the enemy or catch it alive?"

The three of them were stunned, and Harry, who was originally very determined, suddenly hesitated, what he said before was categorical, and now he really wanted to admit who he was going to kill, and suddenly hesitated again.

Hei Bai rolled his eyes when he saw this, he already knew that you didn't have that awareness, a good citizen who had never killed anyone before, and it was not easy to suddenly make such a determination. "Well, then we'll aim first to subdue the enemy, you ...... Do you think Professor Snape is awesome?"

The black and white question suddenly surprised the three of them, and they looked at each other and wanted to despise and ridicule, but they had to admit, "It's amazing, he beat Harold in the second grade at once, and I didn't even see his movements clearly." ”

Black and white nodded, Harold is a character in the second part, and in addition to using the Oblivion Charm, he is simply a parallel import. straightened his collar and smiled lightly: "Then I am honored to tell you that if I want to kill him, I can succeed within a hundred moves! Of course, it is a head-to-head battle!"

"Cut!"

Unexpectedly, Black and White was unanimously ridiculed by the trio. It's just that the black and white expression hasn't changed at all, and it doesn't look like a joke at all. Seeing this, the three of them couldn't help but gradually converge their expressions, and Ron said in disbelief: "Are you serious?"

Black and White gently turned the bone staff in his hand, "Professor Snape's magical strength is indeed very strong, if you can only use magic, of course I am not his opponent." But if there are no limits, I am very responsible to say that he is not my opponent. If I allow a sneak attack, I can kill him with one blow!"

The trio's eyes widened for a while, and in the limited cognition of the three of them, although they knew that there were many strange abilities in the world, they were successfully brainwashed after studying at Hogwarts for three years, thinking that magic is omnipotent, that is, invincible!

Admittedly, a true master is really hard to fight, but you also have to be able to practice to that extent.

In the eyes of black and white, even Dumbledore is not a real master. Especially after meeting Anubis, he was impressed by the ability to stop time with a wave of his hand.

Seeing that the trio didn't speak, Hei Bai laughed twice, and then took out the dragon pattern pan, "This is a pot, you think he is an ordinary pot, but even the Dementors can't stand it slapping." Then he pulled out the Vanguard of Justice, "This is a gun, you can easily take the life of any wizard within sight!"

"Wait, wait!"

Hermione interrupted the black-and-white heretical speech at the beginning, "We know this weapon, but we can't get our hands on it, and we don't know anything about marksmanship." Besides, wizards can also withstand bullets!"

Black and White shook his head boringly, "Are you all brainless? With a gun, you still have to duel a wizard head-on?well, even if you don't talk ......about firearms," he said, pulling out his bone wand again, "Do you know how I used this wand to kill the Dementors?"

Harry was uncertain, "With the Patronus Charm?"

Black and white, "Use a stab!"

“......”

Black and White continued, "That's what I'm telling you, there are many ways to defeat enemies, and you don't have to use magic. Even if you want to use magic, you don't have to use the Death Curse! Although wizards have magical powers, their physical fitness is really poor, and of course they are limited to those who wield magic wands. As he spoke, the images of Gandalf and the Ancient One flashed in his mind, and then he said: "The physical fitness of wizards is similar to that of ordinary people, and even because they don't exercise regularly, they may not be as good as ordinary people in terms of physical strength. And ordinary people will die if they are hit by a car, they will die if they are shot, and they will die if they are stabbed with a knife, it can be said that life is fragile, and it is very simple to take a life. ”

Black and white said and waved his wand, and the two weeds flew in front of Harry's eyes, and for a moment Harry broke out in a cold sweat.

Black and White tilted his head and said, "See, all I did was wrap a layer of ice on the weeds to harden them, and then let them fly out." As soon as the weeds get into your eyes, you're dead!, and the mana I use is only one-thirtieth of the Death Curse!"

The three of them were stunned, looking at the black and white eyes a little solemn, but the black and white eyes glanced back, all kinds of mmp in their hearts! Just now when he cast the spell, he felt a faint sound from behind him, and his vigilant spiritual power spread easily found the little Sirius who had turned into a big black dog.

"Okay, I'll just say you'll get something this time, but it's a good thing you didn't bring Banban here, otherwise you wouldn't be scared away, hahaha!" Black and white laughed and talked about this information again, but the big black dog still hid in the hole in the tree and didn't leave, damn! You deserve to be stupidly in prison, this gives you a chance that you don't use it!

Hei Bai sighed helplessly, and continued: "The principle of the Death Killing Spell is to destroy people's vitality, sometimes it is effective, but most of the time there is a better way to achieve the goal. So with your mana and control, I won't teach you the Death Curse. I won't teach you any of the spells you know, what I'm going to teach you is to create your own spells!"

"Shhh

Black and white could clearly hear the gasping sound of the three people and even the big black dog, if they hadn't read the online article, they would definitely say something terrifying!

Black and white didn't give them time to ask questions, but continued: "Don't be so surprised, your own spell is lofty, but it's actually like that!"

"If you want to create your own spells, you first choose the effect you want to achieve, and it is recommended to choose the effect that you have experienced or are familiar with. Because then you have a deep understanding of the effects of the spell, including the beginning, the process, and the result. ”

"Then you have to calculate the mana, what kind of enemy to use what degree of mana, if the enemy is also a master of strong mana, then with your mana to achieve the effect of the spell, I am afraid that you will not be able to do it. So the effect must be proportional to the mana!"

Harry interrupted with a frown, "What does it mean that the effect is directly proportional to the mana?"

Black and white pouted, and looked at the big black dog without a trace, hey! This thing is still thinking about it, do you still want to go back to school and rebuild?, he replied, "For example, if your spell can make people lose their mana, then if you cast it on Dumbledore, you will not succeed." But if the effect of your spell is only a cut on Dumbledore's finger, then he can easily do it as long as he is under the spell, because this spell determines Dumbledore's skin defense, and Dumbledore's skin defense is not strong. ”

Black and white paused for a moment and explained: "Why is the Death Killing Spell so famous? Because the Death Killing Curse extinguishes the life force, it also determines the life force of a person! And because the life level of the wizard itself is not high, or the vitality of ordinary people is weak, it will take effect easily." ”

Of course, Hei Bai despised the Death Curse in his heart, and Gao Wu had used it before, but it didn't turn out to be very useful. Because there are many strong people in the big universe, such as Wolverine, if you want to use the Death Spell on Wolverine, he will drain your mana in an instant, and then stab you in the paw easily.

"So a good spell has to be done with simple effects. Professor Snape, for example, in the Herbology class, once created a Shadowless Charm when he was in school, and the effect was only to scratch the skin and make the bleeding stop. This is the principle of using the human body to lose too much blood and die. And the criterion for judging is the hardness of the human epidermis I mentioned earlier, but because it adds the effect of the ineffective healing spell, this is not a high-end spell, and it can neither accurately lock the target nor cause the instant death effect, but after all, it is a spell created by him when he was in school, and it is normal to have loopholes. He shrugged his shoulders as he spoke, "If I would target the throat, I don't need to add a restriction that the healing spell is ineffective, because if the throat is broken, the spell will not be able to be recited, and the blood that sprays extremely quickly will kill people, which is also based on the epidermis, but it is more efficient." ”

Ron swallowed, he didn't know what the Shadowless Spell was, but it sounded terrifying. Hermione looked at the frightened looks of the two boys, frowned and asked, "But what if someone performs a healing spell at this time? ”

Black and White raised his eyebrows and smiled: "You spoke for Snape first, you are right, so I have no idea of developing this kind of spell, because it can only be used alone, and it is not easy to use when there are other enemies next to me, and I will get a headshot with one shot with this skill! The easiest way to do this is to dig up the entire wound and then cast a healing spell. Of course, the premise is that the place where you hurt is not a place like your head that cannot be dug up. However, it is also possible to use the method of expelling dark magic to expel this effect first, and then heal it. ”

Hermione pursed her lips, "It's easy to say, but it's hard to get rid of the spell effect. ”

Black and white pouted, "This is what you want to ask, if you have to use difficult methods, what can I do." ”

In fact, there are many ways to exorcise the effects of spells, but it is much more difficult and requires more technology than direct healing, so doctors generally use spells such as healing to treat them. However, black and white has a variety of ways to exorcise spell effects.

For example, using the devouring effect of the Ba Snake Army Formation to suck away the spell effect, the gluttonous beast king can eat any energy. It is also possible to use the power of the Law of Death to annihilate the effect of the spell, although he does not understand the Law of Death, but the Vanguard of Justice and the Bone Staff have this power, which can be easily done.

"Okay, the third thing to note is the spell! your spell must have some connection to the effect you want to achieve. Moreover, language and writing symbolize the inheritance of civilization and have special powers, and the longer the inheritance and the more you understand the words, the more powerful the spells it casts!

There was a slight pause at this point in black and white, which can be regarded as time for the three of them to digest, and it is not difficult to create a self-created spell as simple as it is to do, the key depends on whether you have a flexible and changeable heart. Also, the spell effect changes depending on the enemy, so it can be difficult to create a spell that works with any enemy. After all, most of the mediocre people in this world are the same, but the strong have their own characteristics.

Although Black and White had mastered the method of creating his own spells, he did not succeed in creating his own spells, because he couldn't think of spell effects that could be applied to all strong people for a while! Of course, he was not in a hurry, in order to make the effect stronger, he planned to use the summer vacation to go to the history mission middle school to learn ancient seal characters. However, there is one more point he did not say, because it is not that the older the text, the better, because in some places the ancient language does not fully convey a meaning. This kind of writing is not as good as the one that was developed later, and Harry and the others are native English speakers, so naturally it does not involve this issue, so he did not say it.
