Xiao En's body was stabbed up and down like a needle, his muscles began to tear, and tiny black scales grew on the surface of his skin. As his body grew, the scales also grew larger.

　　 The creature that he was about to become began to appear in his mind automatically. The transformation of Animagus was random. Before that, Sean didn't know what he would become.

　　 "This is a dragon? A two-headed dragon?" The image in his mind is already clear, it is a black two-headed dragon.

Sean has never heard the legend of the double-headed dragon in this world. All the known fire dragons in the magical world are recorded in the book "Types of Fire Dragons". The double-headed dragon he is about to transform is more dangerous and more dangerous than all fire dragons. A strong presence.

The pajamas on 　　 melted into the skin at a speed visible to the naked eye, replaced by hard black dragon scales.

It took about 10 seconds to transform into Sean for the first time. From a one-meter and seven-meter person to a three-meter-long double-headed magic dragon, it has yellow eyes, metallic horns, and a long tail with sharp swords protruding. Like a tail stab, from the fierce appearance, it is enough to stun some timid wizards.

　　 Sean had a sense of unreality at this time. He tried to swing his limbs, but he just couldn't adapt to this new body after he had just transformed, and every step of the movement was very laborious and slow.

The two dragon heads slowly opened their mouths, and the sharp teeth were glowing with cold light. Sean wanted to spray a fire. He raised the dragon head to charge up the launch. However, the first attempt obviously failed, and only a little bit came out of the dragon's mouth. Black smoke, but no flames.

　　 Sean once again set up his posture to spray flames, but from the dragon's mouth on the left, a cloud of white mist came out with snow and ice **** in the mist.

　　 "This, this is the breath of the ice dragon." Xiao En was surprised, didn't he transform into a fire dragon, but an ice dragon.

　　 The Longkou on the right immediately denied Xiao En’s conjecture. A fire spurted from the huge dragon’s mouth, and Xiao En was overjoyed. This is an ice and fire dragon.

　　 There is ice on the left and fire on the right. This is too strong. With the powerful magic resistance, if Sean fights with a dragon body, he can easily deal with an Auror-level wizard.

　　 After experiencing the new body for three minutes, Sean concentrated on his human form. After a while, his dragon body began to shrink and the dragon scales disappeared.

　　 Shaun, who turned back into his body, picked up the magic wand on the ground. He had successfully mastered Animagus, but it would take some time before he was transformed into an instant without a wand like Professor McGonagall.

　　 Xiao En slipped back to the dormitory from the exit girl’s bathroom. After experiencing a painful transformation, his pajamas were already soaked. He took a shower again, put on clean clothes, and immediately entered his dream as soon as he lay down.

　　 In his dream, he saw Chris who had been taken away. Quirrell tortured her with a heart-piercing curse. Sean looked at Chris who was heartbroken for help and suddenly woke up from his dream.

　　 He glanced at the wall clock on the wall. It was only four o'clock in the morning. He only slept for three hours, but he couldn't sleep when he lay down again.

　　 staying awake until 7:30 in the morning, Sean got up to wash, and today the defective Sorcerer's Stone arrived. He came to the auditorium early, wanting to know the rescue plan for the day after tomorrow from Dumbledore.

　　 Sure enough, Dumbledore also looked at Sean and motioned for him to come to the office later.

　　Cassius looked at Kris's position and said, "How many days did Kris ask for leave? When will I be back?"

　　 Xiao En muttered, "I'll be back the day after tomorrow, yes, the day after tomorrow."

　　 Shaun was the principal's office that followed Snape. When he entered, there were already two people in it, one Dumbledore, and a middle-aged man with blond hair and beard. Shaun probably guessed that this person was here to send the defective Sorcerer's Stone.

　　 Dumbledore introduced the beard, "This is Hoff Stark, a student of my good friend Nicole May. He brought the defective Sorcerer's Stone, and he will also participate in the rescue plan the day after tomorrow."

　　 "Sean." Dumbledore called, and then handed him a bright red shining stone.

　　 The first time Sean saw the Sorcerer's Stone with his own eyes, he immediately opened the eyes of the magic. The white light emitted by the Sorcerer's Stone was not as dazzling as Sean had imagined, and was not even half of the wizard's heart.

　　 "Probably the production method and the effect are different." Sean guessed.

　　 Wizard’s Heart is used to increase magic power. It is a source of pure magic power. The Philosopher’s Stone can turn stones into gold and can make elixir. From a functional point of view, the Philosopher’s Stone is more diversified.

　　 "This is the inferior Philosopher's Stone. Voldemort wants to use the Philosopher's Stone to restore his body. This inferior product will make him fall short at the last minute."

　　 Dumbledore looked at Sean and said, "You need to take it to trade with Quirrell the day after tomorrow. When he sees it is a student, he will not be so vigilant. After changing back to Chrissy, the professors will protect you back."

　　 At this time, Quirrell took Chrissy to hide in a corner of London. In order to prevent Helbo from knowing that he wanted to resurrect with the Philosopher’s Stone, Quirrell did not even go to Knock Down Alley.

　　 "After getting the Philosopher's Stone, I summoned all my subordinates, and the British magical world will once again be under my rule." Voldemort said.

　　 "Great master," Quirrell said humbly.

　　 Christmas is still a few days away, Trafalgar Square is full of Christmas atmosphere, red and green decorations with various Christmas elements can be seen everywhere.

　　 The five Hogwarts were scattered around the square, and Sean was standing in the middle of the square, looking around with the defective Philosopher’s Stone in his cotton-padded jacket pocket.

　　 "Quiro!" A person wearing a purple turban appeared in Sean's sight. Although he changed his face, Sean was sure that he was Quiro.

　　 The hooded man also saw Sean. He walked through the crowd and walked straight towards Sean.

　　 "Where is the Sorcerer's Stone?" Quirrell asked straightforwardly.

　　 "Where is Chris?" Sean asked rhetorically.

　　 "You are not qualified to negotiate terms with me. Give me the Philosopher's Stone first, and then I will hand over the girl." Quirrell said.

　　 How could Sean believe his nonsense, doing everything to revive Voldemort, but Sean had no choice.

　　 "She is just a child. I hope you will keep the promise and let her go when you get the Philosopher's Stone."

　　 Quirrell replied with disdain, "Give me the Philosopher's Stone, I will save her life, don't play tricks, or let Old Crouch come and collect the body for his granddaughter."

　　 Xiao En pretended to hesitate and took out the Philosopher's Stone from his pocket. When Quirrell saw it, he snatched it, his expression was ecstatic, and he immediately disappeared in place when he cast his Apparition.

　　 Several people around the Muggles noticed this magical scene, but Professor McGonagall and Snape who came here quickly erased the memory.

　　 "Hough, can you trace the location of the Philosopher's Stone?" Dumbledore asked.

　　 Hoff looked at the metal compass in his hand and said, "Yes, now the Philosopher’s Stone is fifty kilometers southwest."

　　 Before this inferior Philosopher’s Stone was sent, Nicholas Lemay cast him a magic mark, which was so concealed that even Dumbledore could not see it.

　　 And the compass in Hoff's hand is a magic item to track the imprint. Now Voldemort must have returned to his hiding place, preparing to resurrect, and Chris must be there.

　　 But none of the five have been there, so there is no need to apparate, only flying.
