The survival of the fittest is the unchanging law of nature, all kinds of organisms have evolved to adapt to the changing natural environment, each creature has a unique instinct, human beings can hear the normal sound of 20 to 2000 Hz. Anything above 2000 Hz is called ultrasound, while anything below 20 Hz is called infrasound.

Rats, creatures that have lived on the earth for hundreds of millions of years, have the ability to listen to infrasound.

The reason why the Animagus is considered the most complex and subtle spell in the history of magic is that the Animagus form of each individual is uncontrollable and unknown, some can turn into fierce carnivores, and some can become defenseless insects. For hundreds of years, no wizard has been able to solve the mystery of the transformation of the Animagus, a complex and ancient spell.

It is difficult for a fat rat with a body length of 20 centimeters to find a beetle the size of a fingernail in a dark forest with a radius of more than 100 kilometers. But if this mouse has human intelligence, it will be different.

Ron. Weasley often fed his pet Blob with breadcrumbs, fruit, and the magical 'Animagus' transformation spell caused Peter Pettigrew to eat the same amount of food as a normal mouse after turning into a mouse.

This obese spotted mouse cautiously weaves through the woods. If he is attacked by a predator at this time, then Peter Pettigrew will suffer. Hide in the dense bushes and listen to the movement around you. As the night receded, the Aurors, whose investigation had no results, could only appease the centaurs before retreating to the three cordons.

This ghostly fat mouse, after checking that there was no one around, hugged its head with its paws and squirmed violently, and the palm-sized mouse body swelled up as if it was inflated. The fur gradually falls off, the hind paws gradually become thicker, and the two front paws continue to extend. In the end, he became a short and bald man in his forties. His gray hair hung down his cheeks, and the cold sweat on his forehead seemed as if he had just suffered a great pain. Under the garlic nose is a thick lip that is turned outward to reveal two incisors the size of a thumb.

Due to the long stay in the form of a mouse. Peter Pettigrew, still lying on all fours, slowly stood upright. Peter Pettigrew, who hadn't walked upright for a long time, almost lost his balance. Panting, Peter Pettigrew gradually became accustomed to walking upright. Patting the suit that had long been indistinguishable, with a sad smile on his face, he used Animagus to turn into a mouse in order to survive, and had been hiding in Weasley's house for so many years. Living a life like a mouse, for a normal person, the suffering is unimaginable to ordinary people. In order to reduce the loss of mana, transform into Peter Pettigrew, the queen of the mouse. So he stayed in the cage all day and slept and ate, ate and slept.

Rolled up his sleeves, revealing the Dark Mark on his right arm, he became a servant of the Dark Lord by betraying his friends to get a chance to live, even if it was the Dark Mark tattoo, which represented the status of the Death Eaters, it could only be engraved on the right hand, not like the noble Death Eaters like Lucius. Draw the Dark Mark on your left arm. Clench your fists and pour the magic in your body into the Dark Mark. The pattern of the black snake wrapped around the skeleton suddenly came to life, and the black snake wrapped around the skeleton writhed. Peter Pettigrew silently called out inwardly, "Master... Master... I am Peter, I am your faithful servant master... Are you there..."

Although Voldemort managed to escape from Quirrell's body, it was not easy for him to escape back to his lair in the Albanian forest. If you encounter birds, a beetle the size of a fingernail is a rare delicacy, and it will be all over the British Wizarding World. Voldemort, who terrified countless people, died in the belly of the bird.

The little beetle, which was hiding in the dirt, seemed to hear Peter's call. Carefully crawling out of the rotting leaves, he spread his wings and stumbled up. Flew in the direction of the Dark Mark's call.

As the minutes ticked by, Peter, who had his eyes closed, heard a buzzing sound and opened his eyes to look. A black beetle flew in front of him, the Dark Mark was the way Voldemort used to identify the Death Eaters, and it was also a proof of the wizards' oath of allegiance to Voldemort, once the Black Mark was carved, the Death Eaters were able to call Voldemort through the Black Mark mark, and Voldemort was able to summon a Death Eater to his side through the Black Mark mark.

Peter excitedly opened his palms and let the black beetle land on his palm. "Are you, master?" stammered Peter. He hadn't spoken for many years, and now he was making a voice again, which was so weird to hear.

Voldemort's hoarse voice came to Peter's mind. "It's me Peter, my most loyal servant, that you have proved your loyalty to me by appearing in the dark forest when I need you most!"

"Oh... Peter, master, will not change your loyalty to you, even if Merlin is reborn, and I will send you back to Albania," Peter said tremblingly.

"Well, that damn leader of the 'Dragon Thieves' disrupted my plans, and now that Quirrell is dead, my plan to capture the Philosopher's Stone will not be able to proceed! After sending me back to Albania, you go to Malfoy Manor and tell Lucius to find a way to get the notebook I left at his place and into Hogwarts! Voldemort said hoarsely.

Peter Pettigrew was stunned, in order to survive and take refuge under Voldemort, in order to live better, he chose to be close to Voldemort, the Dark Lord, the Dark Lord is strong, then he can still act as James as before. Potter, Sirius Black, Remus. The three of Lupin are like, and they are in full swing. But only from betraying James. After the Potter family, Peter could no longer live in the sun, and could only rely on Animagus to incarnate as a rat and hide in hiding, unless Voldemort could return to the wizarding world, and then as Voldemort's servant, Peter would be able to live like a human.

And the leader of the 'Dragon Thieves Group' in Voldemort's mouth, even Peter, who has transformed into a mouse, knows that it is a group of powerful thieves, but for Voldemort's blind obedience to his strength, Peter does not think that the 'Dragon Thieves Group' will be Voldemort's opponent.

For the Horcruxes made by Voldemort, the older generation of wizards knew this secret, but the pain of splitting the soul was not something that everyone could do, and for normal wizards, Voldemort's extreme behavior for immortality, most people thought it was a madman's behavior.

"Yes... My master! I'll take you out of the Dark Forest in my Animagus form, and then we'll be on our way to Albania via Muggle World Transportation. That way, the Aurors won't be able to track us down," Peter said, holding the beetle in his palm.

A bizarre scene takes place in the dark forest, where a spotted fat mouse carries a black beetle through the dense forest.

Harry. The Potter trio followed the rest of the students to the next class's classroom, meeting students from the other houses along the way. Potter the savior was once again in the spotlight, and the Prophet Times reported that Harry was once again in the spotlight. Potter is portrayed as a brilliant teenager who helps the Aurors solve this case of poaching unicorns. The gaze of others pointed at Harry, who had not experienced the secret room and grew up. Potter felt uncomfortable.

Ron. Weasley kept complaining, "Damn Spotted! It's the fourth day!! Where the hell did it go? ”

"Don't worry, Ron! Didn't you say before that spots sometimes disappear for a while? "Harry. Potter comforted Ron by patting him on the shoulder.

Frowning, Ron. Weasley began, "Yes, when I was at home, Blob would sometimes disappear for a while, but this is Hogwarts, and I'm a little worried!" I'm afraid Filch will catch Spotted and feed him Mrs. Loris... That's miserable."

For the Filch who punished the student for breaking the school rules in a different way, Ron . Weasley had a shadow in his mind. And the black cat beside him, every time he saw his spots, he always showed a greedy gaze, and even Harry. Potter and Hermione. Both of Granger shuddered.

After several fruitless searches, Ron. Weasley could only hope that Spotted would come back on his own, or he would be in trouble when he got home. Lose the heirloom-like pet spots, Ron. Weasley could already imagine his mother furious.

In four days, Peter had already returned to London from the forests of Albania, and using the magical transformation spell of Animagus, a spotted mouse easily slipped into the luxurious Malfoy Manor.

Escaped the house-elves of the Malfoy family. Crawled through the crack in the window into Lucius's study.

Lucius, who was looking through the ledger, happened to be sitting at his desk with his back to the window. Although the body of a wizard is weaker than that of ordinary people, his five senses are more developed than ordinary people. The slightest movement made Lucius turn his head.

Lucius frowned when he saw the spotted fat mouse lying on the window frame, the name of 'Marauder' was a man of the year in Lucius's student days. The four nicknames, the Horned Fork, the Moon Face, the Big Foot, and the Tail Worm, represent the four Animagus forms.

"Tail bugs?" Lucius blurted out the nickname Peter Pettigrew.

The fat mouse jumped off the window frame and lay down on the expensive handmade Turkish carpet in Lucius's study. The body squirmed, and the twenty-centimeter-sized body swelled as if filled with gas, gradually regaining Peter's appearance.

"Lucius, I brought the master's order this time!" Peter Pettigrew said proudly. (To be continued......)
