Brian looked at the time, walked to a utility room on the eighth floor of the castle, and knocked on the door gently.

The door opened, and a Brian looked at him in the door.

Brian handed him the broken time converter he had found on Tanat and left the eighth floor directly.

He walked into a remote empty classroom and watched the last ray of afterglow disappear in the sky.

The Pipi Ghost suddenly floated in and screamed strangely. After seeing Brian, he smiled and used the rope he pulled in his hand to draw towards Brian.

Brian directly recited the leg lock curse to Pipi Ghost, letting his illusory legs merge together, and then pulled off the hemp rope in his hand.

Pipi Gui tried desperately to spread his legs apart, but it was useless to try for a long time. His eyes rolled and he shouted in a broken voice, "Little Devil is doing bad things..."

"Lock the tongue and seal the throat." Brian said lazily.

"Woooooo..." Pipi's words were choked in his throat. He covered his neck and glared at Brian fiercely. After seeing the wand that Brian raised again, he suddenly passed through the wall and disappeared.

Brian smiled and stood up to leave the classroom. After seeing the dirty hemp rope in his hand, he took it away thoughtfully.

He changed the classroom, cleaned the hemp rope, and recalled how to make the door key.

The production of door keys is very simple, and you can make it by just chanting a spell. However, because the use of door keys is easy to get unexpected, it is strictly controlled by the Ministry of Magic and is prohibited from private use.

However, this is just a law. There are always people using this spell privately, so there are endless wizards who are injured or teleported to unknown places.

Brian pointed at the rope with his wand and said, "Mentus."

A feeling of over-electricity made his fingertips numb, and the places he had been to flashed through his mind. He could set the end point, when to set out and when to return.

He set the end point in the alley outside Kings Cross Station, set the departure time, but no return time.

Brian checked it and there was no problem, and a one-way door key was made like this.

He put the door key in his bag, looked at the sky, and took out the map of the living spots he got from Shabini.

"It seems that we have to return the map to them." Brian stood up. He thought that Harry and the others would run out by using this map at that time.

He entered invisible state and walked towards the Gryffindor common room location, stopping at the door of the guards of the portrait of Fat Lady. There were a few stinky trolls guards.

Brian waited for a while and saw Crook Mountain walking over with his tail raised, he smiled slightly and threw the map in front of the big cat.

Crook Mountain was indeed a very smart cat. It sniffed at the parchment and turned around, as if it recognized that it was something Harry and Hermione had once brought, so it held it up and slowly walked into the lounge with its neck legs through the crowd entering and leaving.

Brian sorted out the offensive potion in his hand in a classroom and made a pot of explosive potion.

Next, he pinched the time and asked the house elf to take him to the secret room and exchanged a time converter with himself in the past.

Seeing Slytherin's portrait again, Brian felt a little sad. He glanced blankly and left the secret room with the house elf.

"Farewell, sir." He said silently.

He went directly along the venue to the place where the battle was about to take place, buried the potions he had prepared in the right place, and then invisible and waited silently for what happened next.

"The third week has begun." He looked at the gradually darkening sky and said silently.

Everything that followed happened as scheduled. After Brian walked over again, he dialed the time converter back an hour ago and directly joined the next battle.

Time and time again...

If the first experience was an exciting adventure, then the next more times became an extremely test of patience. Brian had to pour himself a bottle of energy potion so that he could not feel drowsy halfway through.

Later, he didn't even want to use his wand and took out his pistol to solve the problem. After all, everything has happened many times.

Finally, he lasted for the last time, and this time after the battle, he directly captured Peter, a dwarf who was trying to escape in the chaos.

Brian held its tail and did not hold back. He directly used the Soul-Snatching Spell to keep it here honestly.

After taking the compound decoction he handed over from the past, he turned into a witch, which made him feel even more unhappy.

In fact, he really wanted to beat him up. There were so many corpses on the ground, why did he use a witch's hair?

After another familiar battle to vomit, Brian finally breathed a sigh of relief. After all he used the time converter, he found Peter the Pet.

"Change back." Brian said lightly.

The thin bald mouse began to grow bigger and eventually turned into a very short man. His skin was wrinkled, dirty, his hair on his head was messy, and he was bald. His pointed nose and watery mung bean eyes looked like mice.

Petr star Peter cringed his hands and said in a sharp and mouse-like voice: "Would you... have any instructions?"

"Go and find the Dark Lord, Petr," said Brian, "Go and help him resurrect."

Even under the control of the Soul-Snatching Curse, the little dwarf Peter still trembled and seemed very frightened.

Brian thought for a while and pointed at him and said, "All forgetfulness is empty."

Petr's eyes became blank, and Brian made him forget everything that happened tonight and the things that happened in the Death School.

"Harry Potter knows your identity, and the past can no longer be hidden...at least Dumbledore already knows it." Brian guided, "So, the Dark Lord is the only way you can choose."

"He is currently hiding in the forests of Albania and has lost his body." Brian put a small locator on Petr's body and whispered, "Go and find him."

The little dwarf Peter's eyes were still a little dull. He murmured to himself, "Go to find the Dark King... Go to Albania...", and his body turned into a mouse again and disappeared into the dense grass.

Brian canceled the Soul-Snatching Curse, and after the Compound Decoction failed, he turned the time converter again and returned to the past.

This time, he went straight to the position separated from Snape and the others. He saw Snape struggle for a moment and finally released his deer patron saint. It was like an elegant and beautiful elf, with big eyes, long eyelashes, and a lively and gentle look.

Brian summoned his raven patron saint to guard Harry and the other two, and Blake and Lupin. Snape glanced here and used his magic wand to direct several fainted guys to walk out of the Forbidden Forest.

The soul monster finally dispersed, and the deer guardian looked here and then dissipated.

"Great patron saint, sir." Brian glanced at his raven and said sincerely.

Snapeton stopped and looked at him inexplicably gloomy. Brian felt that Snape wanted to recite the forgetting spell to him at this moment.

"Cough, sir?" Brian reminded with a light cough. Your intentions are too obvious, right?

Snape twitched the corner of his mouth and said in a low voice: "Don't tell anyone about this, Brian."

"Of course, sir." Brian blinked and said sincerely.

Snape stopped looking at him, and under his wand, several bodies floated in the air like ghosts. I wondered if it was intentional, Black and Lupin dragged their heads down the grass, and Brian felt that they might get their noses worn off.

Brian glanced at Snape, who was silent and did not make any noise.

The two came to the entrance of the school hospital silently.

Mrs. Pomfrey exclaimed and greeted her. Black was tied up by the professors who rushed over after hearing the news. Professor Flivie put many spells on him, almost tied him into rice dumplings.

"No problem, Minerva went to inform the Ministry of Magic and imprisoned him on the tower first! My office!" Professor Frieve said.

Mrs. Pomfrey carefully checked the situation of Harry and the other two and Brian. She wiped her tears and said, "Poor child, be scared by the dementor..."

He arranged a room for them to stay, and even Brian was ordered to stay for one night to recuperate.

"Look at you, you are tired, child." said Mrs. Pomfrey.

Brian had no choice but to agree.

Next, Mrs. Pomfrey couldn't bear to look at Lupin's bloody and almost flat face, and sighed: "Damn Black, he actually beat Remus like this..." She wrapped Lupin's head with a bandage.

"I think you have to tie him up... He is still thinking about giving Porter to Black tonight." Snape said sarcastically.

"Oh, I can't believe it!" Mrs. Pomfrey cried. She thought for a while and locked Lupin in a ward alone.

Brian lay on a bed, next to him three coma wizards.
