Among the many recorded lists of successful people, Ivan even saw the Dumbledore family, which surprised him somewhat to a bit.

Then, Ivan remembered Dumbledore's Phoenix Fox, and the rumor about Dumbledore's family in Crimes of Greenwald,

[Whenever a member of the Dumbledore family is in desperate need of help, a phoenix will descend...]

Ivan wondered if it had something to do with the fact that they had fused with the phoenix bloodline.

Of course, according to the book, the Dumbledore family is a relatively moderate faction, and even obtained the consent of the other party before conducting fusion experiments, which is probably the reason why Phoenix and the Dumbledore family are so close.

"Huh? How did it break off here? Ivan was reading the book with great energy, but at the end of the book, when he talked about the fusion method, it suddenly disconnected, as if someone had forcibly torn off several pages in the middle, and at the end of the book was some content that was not nutritious.

Just as Ivan was confused that the so-called reward was just some information, the system beep sounded again.

["Bloodline Origin" has been read, and the challenge mission has been activated.]

Challenge Mission: Defeat (or kill) trolls

Reward: Bloodline Fusion Potion Recipe]

"Challenge Mission.." Ivan's heart sank, he always thought that this was a learning system, but he didn't expect that there would be a setting to fight monsters and give things.

Ivan was even more curious about who hid the book here, and actually set up a confusion charm and a special hidden magic in the forbidden book area.

Dumbledore was the first thing that came to Ivan's mind, the greatest white wizard of the century, who had the authority and reason to hide Bloodline Origins.

After all, bloodline fusion is an extremely dangerous thing, and the wizards who die because of this are definitely dozens of times more than those who survive, and this terrifying mortality rate makes this kind of wizard with a special bloodline not become the mainstream of wizards.

In addition, it is possible that James Potter, Sirius and others are also very likely, after all, it is very good to hide some important objects in their style.

And then there's Tom Marvolo Riddle, or Lord Voldemort, who used to be at Hogwarts...

All kinds of speculations flashed in Ivan's mind one by one, but Ivan didn't stay here for long, there were too many things to digest in his brain tonight, even in the face of a large number of forbidden books Ivan had no idea of reading.

On the way back, Ivan's attention was focused on the newly activated challenge mission.

Seeing that the target was a troll, Ivan had a lot of headaches, and he didn't despise the trolls just because Harry and Ron defeated them in the original books.

They were able to win, and the factor of coincidence accounted for a large proportion, if it weren't for Harry's savior's aura that had been playing a role, by the time the professors arrived, the Iron Triangle would have been cold.

Judging from what Ivan had learned from reading the books, the trolls were not easy to deal with, they were large, powerful, and resistant to magic, and even an adult wizard had to be careful when facing them.

Ivan sighed, if it weren't for the fact that he knew from "Bloodline Origin" that fusing the bloodlines of magical creatures could improve magical talents, he wouldn't want to face such a monster in the first grade.

Ivan walked through the silent and uninhabited castle, and the success of his previous arrival made Ivan somewhat let down his guard.

However, not long after he stepped out of a secret passage, a blue, rapidly traveling ghostly light suddenly collided with Ivan.

As if he had been immersed in ice water, Ivan shivered, and when he turned his head to look at it, he realized that it was an ugly ghost with a worn-out hat... Peeves.

Peeves was even more excited, clapping his hands and shouting at the top of his voice.

"Look, see what I found? It's another freshman, come on! There's another one over here! ”

"It's all petrified!" Ivan's backhand was a petrification charm, and the blue-gray light struck Peeves in the chest with precision, but the latter was only slightly repulsed before laughing even more.

"Hahaha.. It's useless, you can't hurt me! Peeves smirked around Ivan, as if trying to drag Ivan here.

Seeing that ordinary magic is useless to Peeves, Ivan is not discouraged, because the ghost is not immune to all magic, and it just so happens that he has a trick of black magic that specializes in spirituality.

"Fear Descends~"

Just as Peeves was grimacing in front of Ivan, a purple light shot out from the tip of Ivan's wand, and Peeves immediately changed his face and crashed into a classroom in the distance screaming, and Ivan could still hear Peeves' shrill screams in the distance.

"No, Barrow, let me go, I swear I didn't do anything bad! And Nick, put your axe down first, we have something to say..."

Seeing Peeves' reaction, Ivan nodded with satisfaction, called up the system's magic bar and took a look, and found that the fear spell had unknowingly risen to level two in the past few days, no wonder the effect was so good.

After dealing with the annoying Peeves, there was another rush of footsteps in the distance, and Ivan remembered that Peeves had said that it seemed that he had found a new life "again".

By the time Ivan was ready to take reed in the tunnels, it was too late, and Harry, Ron, Hermione, and Neville rushed out from across from Ivan.

Harry and the others didn't expect to meet Ivan here, but now was obviously not the time to talk about this, Harry was just stunned for less than a second, and then took the lead in pulling Ivan's arm and dragging him to run.

"Ivan, run! There's no time to explain, Filch is behind! ”

Ivan didn't even finish the words that there was a secret passage behind him, and he was dragged into another aisle by Harryson, so he had to run along.

As he ran, Ivan felt that the scene seemed familiar, and it wasn't until Harry took the lead and stepped into the forbidden corridor on the fourth floor that Ivan realized that something was wrong.

"Quick.. Come on in, Filch is coming! Harry and Neville worked together to pull Ivan in, who didn't want to come in, and Hermione closed the door, and Ron locked the door with great effort.

"Then Filch won't be able to get in." Harry breathed a sigh of relief.

"yes, it's just that we can't go out either." Ivan muttered to himself as he looked at the locked door, then sighed as he looked deeper into the hallway.

"If you want me to say that you might as well go out and face Filch..."

Harry didn't understand what Ivan meant, but soon felt a little sticky on his shoulders, and when he turned his head to look over, he saw three huge heads looking at him, bursts of foul breath coming from their open mouths, and from time to time yellow saliva fell from the edges of the mouths, and some of them splashed onto his clothes.

"Ah~" In the next second, Hermione and the others also saw the three-headed big dog, and the cry of fear suddenly tore through the silence of the night.
