Principal's office, in a meditation pot.

Dumbledore followed William's memory and watched the whole process, and at this time he had entered the most critical part.

Tywin walked quickly towards the Ravenclaw lounge, his wide robe rolling.

"Professor Tywin, why are you here?"

Before Robert could finish his words, Tywin's white right hand grabbed his ebony wand.

"Damn it!" Robert fell to the ground without any resistance.

Tywin took a bottle of blood from his robe, a worn-out parchment roll.

Dumbledore's pupils shrank and said seriously: "Three Volumes of Secret Philosophy, written by the sixteenth-century wizard Heinrich Agripa.

It explains the relationship between the human body, the twelve palaces and planets, and also records the magic of cracking the seal.

I have been wondering before how Tywin bypassed Ravenclaw's magic and forced the ring to get it, so that's it."

Dumbledore seemed to be teaching William, and William listened carefully.

He was not just listening carefully, he was drooling. Although there were many banned books in the library, they were all from the school. What did it have to do with William?

Besides, who would dislike many babies? That set of pampered scrolls is a treasure at first glance.

Professor Tywin held the parchment and turned to a certain page. He used a black crow's feather to stain the blood in the bottle and began to paint something seriously.

The blood did not drop a trace, forming an obscure pattern that was flowing and changing in the air.

He quickly finished all his work, groping in the collar of his robe, and taking out two time converters.

Professor Tywin placed the time converter in the middle of the pattern, and the two objects were immediately suspended in mid-air.

He pointed his wand at Robert's head again.

"Avadassaudi!"

Robert's face twisted, he seemed extremely painful. When the wind blew, the blood beads with blood-colored patterns began to tremble.

This is undoubtedly a magic that requires a blood sacrifice, and Robert is the sacrifice.

With Robert's death, the short needle of the time converter began to spin violently.

A stream of white smoke slowly spurted out from the hour hand and fell on the door knocker with the guidance of the ebony wand.

The door knocker absorbs all the energy of the time converter!

The door knocker let out a satisfying joy. It seemed that he hadn't eaten such a delicious thing for a long time. It greedily asked for more energy.

But Tywin ignored it. He stole three time converters, and now only one is left and cannot be destroyed.

He took off the door knocker excitedly, put it in his hand, dug out Robert's left eye, arranged it on the wooden door, and turned around and left.

These arts were left to Dumbledore!

"Thank you, William," Dumbledore whispered, "Let's go..."

William fell back to the floor of the office, and Dumbledore was already sitting behind the desk. William also sat down and waited for Dumbledore to speak.

"A very complete memory," Dumbledore finally said, "it confirms my speculation and proves that I am right.

Since you came to me and decided to leave the time loop, do you understand?"

William nodded. The whole thing was very complicated. If he were not a wizard with strong logic, he would not understand the whole story at all.

"Professor, the key is that time converter." William carefully said quickly.

The time converter is a device used for traveling time. It looks like an hourglass hanging on a golden necklace. The number of times the hourglass is turned represents the number of hours in which time is traced back.

The reason why the time converter works is because of the "hour reversal curse".

The wizards encapsulate this spell into a small magic-cast hourglass that can be worn by the wizard on the neck and rotated the corresponding number of times according to the number of hours they wish to go back.

William first heard the word "hour reversal curse" in Professor Binnes' class, when Qiu was asking about Ravenclaw's ring.

At that time, William didn't care much because he didn't know the effect of this spell until he was studying a lot and saw this spell in a certain spell book in the seventh grade.

Dumbledore warned William that there was a deep meaning to spend more time studying, and he knew that William would sooner or later discover this spell.

It was also from that day that William began to suspect that Tywin had obtained a time converter so that he could appear in several places at the same time.

Dumbledore also reminded William that the one who attacked the Ministry of Magic was Tywin.

Why did he attack the Ministry of Magic? Because the Ministry of Magic has all the time converters hidden!

This is also because Forge dared not speak out. What is lost is the time converter, which is likely to change history. People will inevitably panic when they hear it.

"Since you know the time converter, you should also figure out how Tywin did it all?"

Dumbledore asked with great relaxation, leaning his back against the chair.

"I have a general idea." William smiled.

The principals in all the portraits no longer pretended to sleep. They pricked up their ears seriously and began to eavesdrop on openly.

William said confidently: "Since four Tywins appeared at the same time, he used the time converter three times in the same time period."

“The first time, it should be when you went to the Tower of Ravenclaw.

I guess that in the initial history you did arrive at the Ravenclaw Tower and then meet Professor Tywin.

He knew he was not your opponent, so he had to use the time converter to make his first crossing, stop at the stairs in advance and wait for your arrival, and then use Voldemort's intelligence to get you back to the principal's office."

Dumbledore nodded and said, "Yes, I heard a warning from Ms. Gray at that time.

If Tywin hadn't insisted, I would have gone to the Ravenclaw Tower."

William suddenly remembered what happened to the branch that day.

At that time, the fat monk of Hufflepuff mentioned the bloody man Barrow to find Ms. Gray, saying that something happened to the Lavenclaw Tower.

Now it seems that Tywin should have sneaked in.

He was either planning to steal the door knocker or confirm whether Ravenclaw's ring was a door knocker.

This Ms. Gray is not simple either. This is the first time William knows that the ghost has the ability to warn!

William suddenly became interested in Ms. Gray.

William's thoughts were distracted for a moment, but did not continue to spread. He continued, "When he was in the corridor on the fifth floor, Tywin met Professor Snape.

But that person was pretended by Tywin using compound decoction, so this time he also used the time converter, but it was definitely not the second time he used the time converter."

"What's the reason?" A trace of admiration flashed in Dumbledore's eyes.

"Tywin, who became Snape, was seriously injured. There must have been several battles in between."

William continued: “In the corridor leading to the tower of Ravenclaw, Tywin encountered another attack.

The attack was intentionally ambushed, both of them were injured to varying degrees, and then they saw Tywin disappear using the time converter.

I think this is his second time using the time converter.”

William stretched out his wand and skillfully stirred the meditation basin. He saw two Tywins fighting appeared in the basin.

"Look, professor." William pointed somewhere.

"Tywin was not injured at the beginning, but was ambushed in the Ravenclaw corridor and the 'Tywin' who was preparing to attack was injured.

After an attack, were the wounds of the two people exactly the same?"

William spoke faster and faster, and he said seriously: "This shows that after being attacked, Tywin used a time converter, traveled back, and then lie in ambush in the corridor.

He didn't know who the person who attacked him was. Although he looked exactly the same as himself, he suspected that someone had also used compound decoctions.

But when time passed, the 'Tywin' who attacked him did not come, but the one who came at the beginning!"

William's words echoed in the office, and all the principals whispered to each other.

William's meaning is very simple. Tywin met another "self". The two of them fought. In order to investigate, he traveled back and lies in the corridor.

But by chance, he was the one who attacked him after traveling back in time!
