Hogwarts Summoning Guide.

Bai Lin had just climbed the small hill when he saw two wizards coming swiftly from the direction of Hogsmeade on broomsticks. Upon seeing someone on the hill, the two wizards lowered their broomsticks and landed.

Bai Lin noticed that the two were dressed in the standard robes of the Aurors. One had squinted eyes, while the other had a shallow scar on his face that had severed his beard.

Looking closer with his small eyes, he recognized Bai Lin by the moonlight and said, "You are... Mr. Kelin? What are you doing here so late?"

Bai Lin glanced in the direction of Hogsmeade out of the corner of his eye, but saw no other wizards. He asked, "Are you here for Antonin?"

Scarface's expression immediately turned serious. He drew his wand and said, "I'm afraid we'll have to ask you to return to the Ministry of Magic, sir. Please do not resist!"

Bai Lin chuckled and said, "I'm afraid I can't let you have your way, gentlemen. I have to inform Headmaster Dumbledore."

When the little-eyed man heard Dumbledore's name, he was startled and his eyes widened considerably.

Just then, two more figures flew over from the direction of Hogwarts on broomsticks. From a distance, Bai Lin recognized one of them as the poker-faced Snape, and Bai Lin immediately frowned. The other person was also wearing an Auror's robe and had a bright red onion nose.

Snape always spoke first: "Kelyn White, you'd better explain why you're outside the castle." As he spoke, he pointed his wand at Whitescale intentionally or unintentionally, but his eyes flickered as he looked at Scarface and Small Eyes.

Bai Lin narrowed his eyes. He noticed something unusual in Snape's gaze and suddenly realized that he recognized the two wizards in Auror uniforms. At this time, Snape was a double agent; if he recognized Scarface and Small Eyes, then these two were very likely Death Eaters.

The three groups faced off. Just as Bai Lin was about to speak, a scream came from Hagrid's hut. Bai Lin thought to himself, "Oh no!" It must be that Harry's kindness led him to decide not to let Black kill Peter, and Peter took advantage of the three's inattention to turn into a rat and escape.

Sure enough, Hagrid's door was kicked open, and Black rushed out first, only to be seen by the three Aurors and Snape.

"Expelliarmus!" Bai Lin aimed at Little Eyes and immediately followed up with "Stun!" to Snape. The speed of the spell was as fast as thunder.

Snape's attention had just been drawn to Black when he was caught off guard and his wand flew out of his hand. But Snape was on guard and tumbled off the broom with surprising agility.

The Auror with the scallion-nosed nose, who had just been looking lazy, was now on high alert. He aimed at Bai Lin and unleashed a "Disarm" spell. Bai Lin was stunned. His hands were empty. What weapon did he have to disarm? After casting the spell, Bai Lin immediately put his wand back in his pocket and retreated towards the hut.

Scarface roared and unleashed a Cruciatus Curse directly at Black! It wasn't that many Death Eaters would hold back and not kill someone outright, but rather that the Cruciatus Curse's incantation was very short and easy to read in battle, yet its effects were extremely cruel.

Lupin, who was following behind Black, shoved Black aside and was immediately struck by the Cruciatus Curse in his place, letting out a scream as he fell to the ground.

"You're all in cahoots!" Snape screamed.

Bai Lin knew that no one would listen to his explanation at this point, so he quickly summoned Xuefeng and rushed towards Snape. Apart from Aurors, no one else could legally use the three forbidden spells. This can be seen from the episode of Goblet of Fire where Mad-Eye Moody demonstrates the three forbidden spells in class. Therefore, Snape could not subdue Xuefeng for the time being.

Bai Lin said to Blake, "Go after Peter!" Then he immediately used "Petrify All!" on Scarface. Blake roared and transformed into a big dog, running after Peter's scent.

However, Bai Lin's petrification spell failed again, and the scarred face showed no reaction. Bai Lin remembered what Antonin had said about the snake monster's blessing, and immediately cursed himself for being an idiot.

Onion-Nosed jumped off the broom, hid behind a rock on the hillside, and cast a Stunning Spell at Bai Lin from a distance. He didn't go all out, so he was probably not a Death Eater, but an Auror who came to Hogwarts because of the Fat Lady incident.

Bai Lin swiftly drew his wand and shouted "Epatimanta (Obstacles)" at the earthen mound in front of him. Instantly, an earthen wall rose up in front of him, blocking the Stunning Curse.

Lupin was writhing on the ground in pain, and Harry behind him was terrified, not knowing what was happening. But then, the suffering Lupin began to change. White hair grew all over his body, his eyes turned red, his face grew longer and longer, and long fingernails grew on his fingers.

"Harry, watch out! Lupin is about to turn into a werewolf!" White Scale shouted to Harry, leaning against the earthen wall.

Harry received too much unbelievable information that night. First, Black, whom he thought was his mortal enemy who killed his parents, turned out to be his godfather who had been wrongly accused for twelve years. The rat pet that Ron thought was sickly turned out to be the traitor who betrayed his parents. Lupin, the teacher who he thought was just teaching him Defense Against the Dark Arts, turned out to be a dark and cruel werewolf.

But the summer training paid off at this point. Harry didn't falter for long; instead, he retreated to Hagrid's hut and pulled out his wand.

From behind the rising earthen wall, Bai Lin called out towards the man with the onion-shaped nose, "Mr. Big Nose, do you know those two Aurors? They could very well be Death Eaters!"

Onion-nosed man paused, stunned, behind the rock. Things had happened so fast. He realized he hadn't seen the two wizards in Auror uniforms before. And they'd just met and immediately used a forbidden spell, which, even against the fugitive Black, didn't conform to Auror law enforcement procedures.

Snape hid behind Onion Nose, his eyes darting around, unsure whether to help Scarface take down Onion Nose or help Onion Nose deal with Scarface.

At this moment, the little-eyed man had retrieved his wand and stepped forward, pointing it at the white-scaled earthen wall as he shouted, "Redktoo! (Shatter to pieces!)"

With a loud bang, the earthen wall exploded violently, as if hit by a grenade.

Bai Lin protected his head and rolled aside in the explosion, a surge of anger rising within him. Although he didn't want to use forbidden spells lightly, especially since he couldn't confirm that the other party was an imposter Auror, he took advantage of the huge cloud of dust generated by the explosion of the earthen wall and aimed at the room with the small eyes, shouting: "Divine Edge Without Shadow!"

A wind blade slashed towards Little Eyes. Little Eyes quickly cast a protective spell on himself, but Bai Lin's casting speed was much faster. Immediately afterward, "Blazing Fire! Blazing Fire!" Two fireballs flew towards Little Eyes from the left and right sides. Little Eyes rolled on the spot, but was still grazed by one of the fireballs.

"Avada Kedavra..." Scarface took a few steps forward and unleashed a deadly curse at the white scales emerging from the dust.

"Expelliarmus!" Before his killing spell could even be fully uttered, another curse struck his wrist. It was the onion-nosed Auror who peeked out from behind the rock and cast the spell on him.
