Became good friends with the Boy Who Lived

"Harry Potter!" A Slytherin girl pointed at Harry and screamed, "Catch him quickly and hand him over to the Dark Lord..."

"That's enough!" Professor McGonagall said angrily, "Slytherins don't have to join the battle, but you can't cause trouble either. Go back to your basements and don't come out! Do you have any objection to my handling of this matter? Severus?"

"No!" Professor Snape glanced at the students of his college with a sinister look, and said in a cold voice, "Slytherin prefects, organize your classmates to return to the basement. I will seal the basement temporarily. No one is allowed to enter or leave without my permission!"

Aes pulled out a palm-sized jade slip from his pocket and threw it on the ground without hesitation. With a "crack", the jade slip broke into pieces, and most people's attention was attracted.

The jade slip was a switch. As it was smashed, a mysterious feeling spread out, and the Hogwarts defense formation was activated. Everyone looked at the ceiling of the auditorium as if they were sensing something.

"Professors!" Aeris said loudly, "Students in grades six and seven, go to the open space outside the castle and use protective magic to reinforce the protective formation. I need some time to call for help!"

"Don't just stand there, you all heard what Professor Grindelwald said!" Professor McGonagall said loudly, "Deans of each college, organize the students to take their positions. If you need any help, just tell me, Aris!" Professor McGonagall patted Aris on the shoulder, her eyes full of pride and pride.

Professor McGonagall began to give orders: "Students below the fifth grade, hide in the secret passages... Mr. Clifford, you cannot participate in the battle..."

Harry, Hermione, Ron, and Draco gathered around Aris. "Is there anything you can do for us, Aris?" Harry asked.

"Follow me!" Eris didn't act pretentiously. He led the four people and walked quickly outside the castle. In an open area, Eris made some arrangements. They met many people along the way...

Alastor Moody was limping up the stairs with difficulty. He glanced at the few people and said in a rough voice: "Boys...stay alert at all times..."

Remus Lupin and Sirius were also looking for their own combat positions. Remus saw Aris and Harry and stopped them.

"Eris, Harry..." Remus took a deep breath, forced a smile and said, "Nido is pregnant..."

Hermione covered her mouth and said in surprise: "Congratulations... Remus..."

Remus nodded, and then said: "For my future child, I will fight to the death. If anything happens to me...Eris, I hope you can be the godfather of my future child..."

"I think Sirius is more suitable than me..." said Aeris, "You know, Remus, after all, I'm still a minor..."

"When Remus' child is born, you will be an adult!" Sirius said, "I am not sure whether I can survive after this battle. To be honest, the world without James is too boring. I want to find him earlier..."

"Sirius..." Harry said quickly, "Don't be silly, you still have me..."

"Unfilial descendant..." Phineas Nigellus Black broke into a picture frame on the wall, pointed at Sirius' nose and cursed, "You are the only direct descendant of the sacred Black family. Do you want the Black family to be erased from history? Even if you die, how can you face your ancestors..."

Sirius was not afraid at all and started to curse at a portrait.

"None of us will die!" Aeris said firmly to Remus. "See you later, Remus..."

Aris dragged Harry and the others out of the castle. It was a bit chaotic everywhere. Aris also saw Neville talking to his father and mother...

Neville: "Dad, Mom, you shouldn't have come. I'm enough here..."

Mrs. Longbottom: "You little brat! Do I really need your protection?"

Many people are cheering each other on and encouraging each other...

Aris brought Harry, Hermione, Draco, and Ron to a relatively open place. They were surrounded by professors and students who were casting protective magic into the sky to strengthen the protective formation. Aris ignored them and pointed his wand at the ground.

A huge and complex magic circle lit up its patterns. Aires asked Harry, Hermione, Draco, and Ron to stand on a node of the array respectively, and Aires stood in the middle of the circle of four people.

"Take out your wands, guys!" Aeris said, "Use magic on that array node. The spell is very simple...Magic Infusion..."

The four of them nodded at the same time, and four sounds of "magic infusion" rang out almost at the same time.

Aes stood in his place and muttered:

"...the great duke who made a covenant of pure silver and iron and foundation stone;"

"...the surging wind is blocked by four walls and the four doors are closed;"

"...released from the crown, wander at the fork in the road to the kingdom;"

"...fill it up...fill it up...fill it up...fill it up...fill it up...fill it up..."

"...repeatedly, the next is five;"

"...But when it is full, it is time to abandon it;"

“Declare:”

"Your body is at my command; my fate is at your sword;"

"If you are willing to follow my call, obey my will, and go along with my principles, then respond;"

“I hereby swear:”

"I am the one who has accomplished all the good deeds in the world;"

"I am the one who monitors all the malicious intent in the world;"

"You have been haunted by the three great word spirits for seven days;"

"From the wheel of restraint;"

"Appear, guardians of the scales..."

"Magic infusion..."

Various lights began to appear in various places in the castle, and some beams of light even shot up into the sky...

The pattern of the magic circle under Aeris' feet gradually lit up, and then the golden light shot straight into the sky.

At the same time, the Forbidden Forest, the Black Lake, the direction of the school library, and the location of the Lisletlin secret room in the castle were all filled with various colors of light...
