The new semester has begun, and with it comes the news of Nicol Lemay.

"You mean...... The black aura left behind by Helbo is almost identical to the composition of Murphy?" Dracula looked at the bronze mirror in front of him carved with a phoenix float and said in surprise.

Lemay's old and thin face appeared in the bronze mirror, and at this time, his originally amiable and smiling expression was extremely solemn.

"That's true." "Whether you look at the amount of mana in it or the properties of the two energies, you can see that the two energies have very similar qualities," he said.

"I don't know if anyone else has ever thought of comparing these two energies before, but at least in the past six hundred years, I have never seen the energy produced by a dark magic item like a Horcrux, it is too rare."

"Silence may be more well-known than Horcruxes, but it's also less common, and wizards who have the opportunity to observe Silence's energy properties are even rarer......

Lemay's gaze looked through the bronze mirror into Dracula's eyes, "So I'm guessing Newt may be the first wizard to spot the similarities between these two energies!"

Dracula frowned slightly.

He held the phoenix float mirror in one hand, and pushed open the front door of the Defence Against the Dark Arts classroom with the other, looking at the young wizards who were sitting precariously in the melodious sound of the class bell.

"In this class, you will study on your own, and you will review what you have learned before, and you will have a class test in the next class." He said to the little wizards.

Dracula then slammed the classroom door and walked down the stairs connected to the classroom back to the Defence Against the Dark Arts professor's office, leaving only the young wizards in the classroom staring at each other.

"Hey, Potter, Wes, does Professor Dracula often let us study on our own?"

Rove Scamander, who had been removed from his first and second years by Dumbledore, sat in the Defence Against the Dark Arts classroom and asked the Gryffindor pair at the table next door.

"You're glad you be, Scamander." Ron quietly glanced at the front of the classroom to make sure that the classroom door was completely closed, and then said to Rove reassuringly, "Professor Dracula rarely asks us to study on our own, and if we do self-study class, there must be something else that has piqued his interest and made him too lazy to go to class."

"You may not have realized how cruel Professor Dracula's class is when you first arrived, but it's a stroke of luck to have a self-study class in the first period of the new semester!"

"Is Professor Dracula's class so cruel?" Looking at Ron's cautious expression, Rove was a little confused, "Are you overreacting, I heard my grandfather say that Professor Dracula is very powerful?"

So far, Rove has only taken Riddle's Defence Against the Dark Arts class at Hogwarts, and has not heard Dracula's class.

Not only the class, but also after Dracula gave himself a vacation very willfully, even the dueling club he hosted was in a state of suspension, and Rove had never seen the club's "pomp", so he didn't quite understand Ron's prudence.

"That's because you didn't participate in Professor Dracula's physical training!" Harry also turned his head to look at Rove and whispered to him, "Now that Professor Dracula is back, the dueling club should be reopened, you can come and see it." ….

"Trust me, as long as you participate in the Devil Training at the Dueling Club, you won't forget Professor Dracula's horror!" He patted his chest and assured Rove.

"Harry, Ron, it's class time!" At this moment, Hermione, who was sitting in the front row with unkempt hair, turned around and whispered a rebuke with a serious face.

Harry hurriedly picked up the quill and pretended to be learning.

Ron, on the other hand, was a little more annoying, elongated his tone, and responded in a procrastinating tone:

"Got it, Her-Min——!

When Hermione turned around, Harry and Ron gathered together and whispered again in a lower voice......

……

After returning to the Defence Against the Dark Arts professor's office, Dracula thought about it and felt that he couldn't tell it through a mirror, so he simply teleported directly to Paris.

51 rue de Montmorency, Maison de la Le May.

As a dark moon crept in, Dracula's figure appeared in the living room of the house, which had experienced more than five hundred years of vicissitudes.

As soon as Dracula stepped out of the dark moon, he walked to the left wall of the living room and pushed open an old door.

Inside this door is a studio, which has a lot of things and looks a little cluttered, but a closer look reveals a special order.

There is a cabinet in the studio, inside which large and small glass bottles and tubes are stored, and an open, padlock book engraved with a phoenix float stands upright against the edge of the cabinet.

The pages of the book are connected to the phoenix relief bronze mirror in Dracula's hand, and an elegant picture frame on the page connects to the mirror, showing Dracula's figure and the scene inside the studio.

"Nicol, how did you come to your conclusion?"

Dracula casually put away the bronze mirror and walked quickly to Nicol Lemay's side.

At this time, Lemay was sitting on a chair next to a workbench, looking solemnly at the countertop filled with intricate alchemical objects.

"Brad, come and see here." He glanced at Dracula and pointed to a metallic alchemy balance on the workbench, "You should know how useful this balance is, it can analyze the difference between two different kinds of matter."

"yes, I know." Dracula nodded, "As long as the volume of the two substances is the same, this balance will be able to distinguish the difference in their magic, mass, and composition."

"It seems that you haven't forgotten all the alchemy in the hundred years you have been asleep." Even though Lemay's expression was still a little solemn, he still couldn't help but joke with his old friend.

"Don't bother with you, I have a good memory." Dracula shrugged, "Tell me what you've done, I'm supposed to be in class right now!"

"You're still in class, you're here?" Lemay glanced at Dracula in surprise, but nodded in understanding the next second, "Oh, if it's you, it's normal?"

He picked up a glass bottle from the side of the scale, used his wand to pick out a wisp of black mist from the bottle, and placed it at the left end of the scale.

As soon as the black qi entered the range of the scale, it seemed to be enveloped by a magical power, and it was impossible to escape the balance tray with only one plane. ….

At the same time, the left tray of the scale slowly sank.

"This is something you sent, the black gas produced during the resurrection of Helpo collected from Mount Olympus." Lemay said.

He then closed the lid of the glass bottle and picked up another test tube, which also contained a black mist-like object.

"This is the silent sample I asked Newt for." Lemay introduced to Dracula, "But although Mooran has lost its host, he still retains a shallow consciousness, and there is still a possibility of ***."

"In order to prevent silence, I had to let Newt calm it down, and then very carefully collected a very small number of samples. That's all there is to the sampling here."

In order to prevent waste, he very carefully picked up a wisp of mist that had been sampled from Silent Ran's body with his wand, and immediately asked Dracula to help cork the tube, and then placed the sample on the right tray of the scale.

Lemay then gently rotated one of the knobs at the top of the scale.

Several different letters were inscribed on the knob, and he twisted one letter, "eight", in the direction facing him.

The tray on the right side of the scale is gradually descending, while the tray on the left side is slowly rising.

Eventually, the two pallets came to an almost identical level.

"The quality of the two samples is basically the same." Lemay said.

Dracula nodded, and reached out to reorient the knob above the scales for Lemay.

Now, the "M", which represents "mana (na)", is facing the front.

The trays on the left and right sides floated up and down slightly for a moment, and finally still

Almost the same height is retained.

"The mana content of these two samples of the same size is basically the same, right?" Dracula asked in a deep voice.

"That's right, and it's more than that." Lemay bowed his head slightly, and shifted the knob to the other direction......

In the end, Dracula saw on this alchemy balance that the samples on both sides were almost the same in terms of quality, density, toughness, and magic content.

This can completely prove that the black gas produced by Helbo is exactly the same energy component as the foggy object in Silent Ran's body.

"Did you find out what the reason is?" Dracula asked, somewhat confused, "I don't see any similarities between the two, except that they both belong to the realm of the dark arts."

"It's not clear." Lemay shook her head and said, "It's a pity that there aren't any more samples of other energies, otherwise we might be able to analyze the correlation between them."

Dracula propped his chin with two fingers and looked at the specimens on either side of the scale, frowning slightly.

Although these two different energies are both black, and although they are both gaseous or foggy objects floating in the air, the difference in shape and appearance is quite large-

The black gas produced by Helbo's repeated resurrection is a gas, similar if it had to be described as anything else, similar to the black smoke emitted from the chimneys of Muggle factories.

The silent black mist is different.

The black fog in the body is often wrapped by a layer of transparent oily substance, and after cutting through this shell, you can find that the black fog inside is not just foggy, and the black particles in it sometimes condense together to form flocculent objects. ….

Therefore, the difference between the two substances is fairly easy to discern when judged only with the naked eye.

However, with Newt's keen observation, its deeper forms of energy are unearthed. After weighing Lemay's alchemy balance, he found that the two substances that were originally unrelated to each other were actually the same!

Seeing that Dracula was lost in thought for a long time, Lemay made a move first, preparing to receive the two hard-won energy samples into the corresponding glass bottles and test tubes.

"Wait, don't take it yet."

Dracula spoke suddenly.

The wand that had already picked up the black gas came to a halt in the air, and Lemay paused in his movements and turned to look at Dracula.

"Anything new?" He asked.

"I'd like to make another comparison." Dracula looked at the alchemy balance in front of him and said softly.

He removed his left hand from his jaw and extended his long, white index finger to the left tray that had been emptied by Lemay.

A cloud of blood-red energy condensed in Dracula's fingertips, pouring out on the tray on his left.

Originally, without the support of the sample, the left tray, which had been raised high, slowly descended as the blood-red energy expanded and expanded, until it remained on the same level as the right tray.

Dracula withdrew his index finger, which was on the left side of the tray, with a rare look of confusion.

Lemay looked at the alchemy balance in astonishment, only to find that the volume of energy on the trays on both sides was exactly the same!

"It's ......"

"This is the purest dark energy in me." Dracula whispered.

He looked at the ends of the scales in a daze, then raised his hand to look at his fingertips, and slowly said his conclusion.

"That's the case...... Are all the energies that belong to darkness the same substance?" Dracula muttered.

[To tell the truth,Recently, I've been using a change source to read books and chase more,Change the source switch,Read aloud with more timbre,.huanyuan.Android and Apple are available.】 】

Lemay hesitated, then poked his wand into the tray on the right side of the scale.

"I haven't done all the comparisons yet, so I can't just draw conclusions." He said, "Try Mooran for Helbo's black gas."

The black gas that fluttered around the tip of the wand and had not yet had time to be filled into the glass bottle was placed on the tray on the right, and immediately, the black mist extracted from the silent body was picked up from the tray by Lemay's wand

Get up.

The scales shook slightly for a moment due to the energy fluctuations on both sides.

Time passed, and the shaking became smaller and smaller.

Eventually, both ends of the scale stop at the same level.

"Indeed, Brad, the dark energy in your body is almost the same as the black energy of Helbo." Lemay took a deep breath and said slowly.

"So...... Is that what it means that all the different kinds of dark energy are actually the same substance?" Dracula asked, frowning.

"Probably." Lemay smiled lightly, "If that's the case, then this experiment we made seems to have little practical meaning other than to add a definition on paper to the theory of the dark arts."

"Perhaps." Dracula pouted noncommittally, "I'd like to know more now why the dark energies are from the same source?" ….

"That's a very broad question, Brad." Lemay sighed, "But it doesn't seem like a problem for you. Your time is almost infinite, and you'll be able to figure it out one day."

"In the same way, if you really want to figure it out, then it seems that life that has been boring you has to add some other meaning." Lemay chuckled softly.

Dracula shook his head slightly.

His eyes were so deep that he didn't know what he was thinking.

……

The night of the Scottish Highlands is like a brush dyed with ink, and the sky is covered with a brush.

A cold moon in winter slowly outlines a floating shadow from the sky.

On the east side of Hogwarts Castle, there is a beating willow that had been damaged by two mischievous little wizards last semester, and it has been restored under the careful care of Professor Sprout, and its branches are shaking in the cold wind, as if it is dancing some trend.

The cold wind beat against the castle windows, causing the windowpanes to sway, making a clanging sound.

Two fiery red-haired, identical-looking little wizards passed by the swaying window, smiling and chatting with their dark-skinned roommates about the day.

"Lee, have you heard, Professor Dracula gave the students a day of self-study class today!" George looked unfathomable and put his arm around Lee Jordan's shoulders.

"Really?" Lee Jordan had a black question mark on his face and a look of disbelief on his face, "Professor Dracula disappeared for so long, and just came back to give self-study to his classmates?"

"Of course it's true." Seeing Lee Jordan's skeptical expression, Fred said with some displeasure, "Don't you still believe the news channels of the two of us?"

"That's not what I meant...... Lee Jordan hurriedly waved his hand and explained, "I just didn't think Professor Dracula would do this, did he get impatient with the lecture and start messing around?"

Even though he hadn't dealt with Dracula like the Wesley twins, Lee Jordan still had his own perception of Defence Against the Dark Arts professor.

In fact, after more than a year of getting along, almost every student at Hogwarts has gained some understanding of their Professor Dracula, and they have all learned several characteristics of Dracula -

First, Professor Dracula is very strong, very strong, and the weakest is not much weaker than Headmaster Dumbledore, because the old headmaster seems to have nothing to do with the professor's wayward behavior;

Second, Professor Dracula is lazy, he will never stand against a wall, and if he can lie down, he will definitely make a bed for himself;

Thirdly, and most importantly, Professor Dracula is bored and has always been interested in only interesting things.

According to the discoveries of the young wizards over the course of more than a year, they realized that Professor Dracula's coming to Hogwarts to teach was probably just a ticket in nature, and that when the day came when the job of teaching was not attractive enough for him, he would probably abandon his students and leave Hogwarts very willfully......

This is also the reason why Lee Jordan thinks that Dracula is starting to get impatient with the lectures.

"By the way, do you guess tonight's dueling club will take place on time?

Lee Jordan asked, "It's been two months since I participated in Professor Dracula's devil training, which is a good thing, but why do I feel a little missed?"

"I guess you might just have itchy skin, just get beaten up." Fred smirked and said, "I can help."

Lee Jordan's already dark face became even darker, and he kicked Fred's ass, looking a little depressed after being easily dodged by Fred.

"We don't think Professor Dracula will leave so easily." George was a little more reliable than Fred and answered another question from Lee Jordan, "We made a bet with Professor Dracula at the beginning of last school year!"

"Professor Dracula bets he'll teach us until we graduate. If he just leaves, won't those galleons be completely ours?"

Speaking of this, George smiled.

"Forget it, I knew I wouldn't be able to ask you two anything." Lee Jordan gave the twins a middle finger and continued to walk forward, "Let's go, when we get to the auditorium, we know that the dueling club can't be opened yet."

The three of them walked through the tall entrance of the auditorium together.

I saw that the dueling platform in the middle of the auditorium had stood up for the first time in a long time, and Dracula's tall figure was standing in the center of the stage.
