When the Great War broke out, Gryffindor nimbly attacked the black dragon with his sword in hand, and the black dragon kept struggling.

At this time, Gryffindor also noticed that something was wrong, the strength of the black dragon was too weak, and it seemed that he was thinking about something.

"Dragon Eggs!" Gryffindor saw that there was a dragon egg under the Black Lake, but strangely, the dragon egg was dead and had no soul.

"Aang!"

The black dragon rushed towards Gryffindor, the blow was so powerful that Gryffindor didn't dare to hold it up, he hurriedly dodged.

But the black dragon's attack seemed to lock on him, and he was hit in the back.

Gryffindor was wounded, but the black dragon was not feeling well.

The black dragon glanced weakly at the dragon egg below, and his huge dragon boy kept flickering, full of guard and vigilance.

"Do you think you can win?" The black dragon subconsciously protected the dragon egg road.

"Hahaha!" Gryffindor came to the top of the black dragon's head at some point, only to see him raise his sword and slash into the black dragon's head with powerful magic.

"Aang!" The black dragon's mournful voice rang out, and it fell to the bottom of the lake.

The black dragon got up, and was about to lash out at Gryffindor.

But Gryffindor had an extra dragon egg in his hand.

"You're thinking about being reborn, haha, your soul is tied to it, aren't you?"

"No, what are you going to do!"

"Hey!" Gryffindor raised his sword and stabbed it into the dragon's egg.

"Aang!" The black dragon continued to roar, setting off huge waves at the bottom of the lake, and the entire black lake was in turmoil.

"Bang!" The huge black dragon fell to the ground.

The shattering of the dragon's egg hurt the black dragon itself.

At this time, where the dragon egg was located, a crack suddenly appeared.

Suck!

A powerful force sucked into the surroundings, and then, a wave of dead air rushed out of the rift, quickly enveloping the surroundings.

Gryffindor sensed something was wrong, and he hurried out of the Black Lake.

At this moment, a transparent contract rushed out from the direction of the Forbidden Forest and shone on the Black Lake.

The wounded black dragon is protected by the contract.

"Contract?" Ravenclaw arrives on the Black Lagoon and makes eye contact with Gryffindor.

Soon after, Slytherin also came.

"What's going on, why is there such a big commotion?" Slytherin looked at Gryffindor dissatisfied.

"There's a black dragon down there, and when I cripple him, a crack pops up, and then a contract flies out of the Forbidden Forest, and that's it."

Gryffindor said casually, nonchalantly, "Ravenclaw, look at what this contract says, I don't understand this."

Ravenclaw nodded, stepping forward to check.

Soon she frowned and said, "The black dragon and the forbidden forest on the side have signed a contract to help each other and kill the black dragon, then the forbidden forest will avenge the black dragon."

"Oh, that's ......," Gryffindor said, holding his sword, "then kill them all, and the Forbidden Forest will be ours too."

Ravenclaw stopped him.

"Hufflepuff has gone to the Forbidden Forest, we have to wait for news from her, as for the black dragon, seal it first, and we'll see later."

"We should look at the dead air now, they're devouring magic."

Ravenclaw gently stroked the dead air that emanated, full of doubt.

"Remove the rift."

With that, she entered the Black Lake.

The rest of the group followed.

Reaching the crack, Ravenclaw sensed the danger, and the other two did the same, looking at the crack solemnly.

"What was there before?" Ravenclaw is definitely authentic.

Gryffindor gestured to the broken dragon egg.

Ravenclaw looked at the black dragon that had fallen to the ground, and the dragon egg.

She said, "Most of the power of the black dragon has been used to suppress this rift."

"But he doesn't mean well, he wants to make the dragon egg adapt to these dead air, and then release this dead air, this

It's his world."

"These deaths are dangerous, and ordinary wizards quickly lose their magical powers in such an environment, as do some magical creatures."

[At present, it is the most complete and best app for listening to books, integrating 4 major speech synthesis engines, over 100 kinds of timbres, and it supports offline reading

God is still there."

Gryffindor stepped forward to comfort Slytherin, but Slytherin slapped his hands away.

"Get out." Slytherin stared coldly ahead, not knowing what he was looking at.

Gryffindor frowned.

But he didn't say anything, he was going to go to the Black Lagoon to have a look.

This is the end of the scene, and Gryffindor and Grindelwald return to Durmstrang's headmaster's office.

"The four of us kept this discovery under wraps, but everyone changed because of it."

"Slytherin became obsessed with the magic of death and wanted to find a way out of it, so he built a secret chamber underground to ensure the safety of his students."

"Ravenclaw spends all day researching time magic ......"

"Hufflepuff was silent when she came back from the Forbidden Forest, but she quickly picked herself up because I was also getting grumpy, and the whole atmosphere at Hogwarts was panicked, and she had to take care of the students."

Gryffindor finished speaking, and looked at Grindelwald.

"We've tried, for millennia, but Slytherin and I have determined that there is no way to save this world."

"But we are not without gains, at the very least, we have found God's way out of this world."

"Son, it's not that we have given up on this world, we have to find a new life."

"Not everyone is going to destruction, we can guarantee that the highest group of people in this world will leave and go to the place where God goes to find the future."

Grindelwald frowned when he heard Gryffindor's words.

"I'm just here to tell you first, maybe Ravenclaw's last attempt will succeed, haha, though there's little hope."

Gryffindor smiled wryly.

"When we start, we'll come to you."

Gryffindor left, but Grindelwald departed.

"Rozier, take a good look at Durmstrang, I need to go to Hogwarts."

Soon after, Grindelwald appeared outside Hogwarts, and the Headmaster's permission was required to enter Hogwarts.

At this time, it was Halloween, and Snape was looking at the little wizards below with a headache, hoping that they would be obedient.

"Why would Snape be acting headmaster, Brie?" Hermione muttered at the dinner table.

On the other side, Ron lowered his head and didn't dare to speak.

Harry was still quiet, as if he had something on his mind, and the smell of potion on his forehead was terrible.

Hermione slapped her nose.

"Harry, if you hadn't dressed up as a swamp troll today, I'd have driven you away, your smell is too strong."

Goo-goo...

An owl flew down to Snape's desk.

Snape opened the letter and looked at it, and immediately got up.

"Professor Sprout, I'm sorry you to keep an eye on these guys." Snape walked out of the hall.

Professor Sprout nodded slightly, but was not prepared to restrain the children.

"Professor Sprout, do you know where Brie has gone?" Draco stepped forward and asked Sprout.

Professor Sprout shook his head.

"I'm sorry, Mr. Malfoy, I'm waiting for Brie to come back."

……

On the other side, Snape let Grindelwald in.

"I don't think sir is here to make trouble." Snape looked directly at Grindelwald.

Grindelwald frowned.

"I feel Dumbledore's breath disappear."

Instead of going to see Snape, Grindelwald walked towards Hogwarts Castle.

Snape followed, and he wouldn't have let Grindelwald in if he hadn't learned from Dumbledore that Grindelwald was coming to Hogwarts.

And a great wizard might be helpful in such a situation.

Grindelwald seemed to know the location, and went straight to the eighth floor.

Snape opened the door to the Room of Requirement.

Inside, Professors Flitwick and McGonagall remained motionless.

"Grindelwald!" Professor Flitwick exclaimed.

McGonagall, on the other hand, calmed down and looked at Snape, who nodded at her.

Grindelwald was stunned when he saw this.

"Time, they reversed time?"

"It was Lord Ravenclaw who did it, and she brought them." Snape explained.

Ravenclaw?

Grindelwald frowned, he remembered what Gryffindor had said, and Ravenclaw was making a final attempt.

Grindelwald set his sights on Professor McGonagall, who was maintaining his mark magic with Dumbledore.

"Open!"

Grindelwald raised his wand and pointed at Professor McGonagall.

A phoenix symbol appeared on Professor McGonagall's body, and the symbol flew towards the coffin, and a time vortex immediately appeared in the coffin.

Grindelwald did not hesitate to flee into it.

！

！

Soon, the time vortex vanished.

"Oh." Professor McGonagall was at a loss, and of course, she couldn't move now.

Professor Flitwick's eyes widened and he was silent.

Snape also looked ugly.

"I thought he was going to do something, huh." He sneered, feeling only that he had done something stupid and let in a ridiculous old lion.

……

Christmas is over, and Hogwarts has a new professor.

"This is Professor Horace Slughorn." Snape introduced, "Professor Slughorn will be the new Potions professor, and I will replace Dumbledore as Defense Against the Dark Arts professor."

"Professor Lupin continues to be my deputy......

Professor Horace Slughorn was a stocky old man who looked energetic and relatable.

However, some people who know him will not think that he is really good.

After introducing the new professor, Snape finished speaking.

Some of the young wizards tried to inquire about Brie's whereabouts, but Snape stopped them.

"Why don't you put your mind on studying, natural magic is studying on your own for the time being, this is the time to test your learning, please surprise your headmaster Oude."

Surprise...... Not having Brie is a scare.

Especially when Snape became acting headmaster, no wizard wanted to look at Snape sitting in the headmaster's seat every day.

"Oops, I think even Voldemort is better than Snape as Headmaster." Ron grunted with his head down.

Harry on the other side gave him a strange look.

Hermione was silent.

"Actually, Professor Snape is a pretty good man, and we should trust him...... Especially in Brie...... Leave the case." Harry's voice was very quiet.

His heart was full of self-blame, but he didn't know why he was so impulsive, and he wanted to go back in time and save his parents at the hands of Voldemort.
