Wanting to get out of the time loop is as simple as figuring out the whole thing.

It may be difficult for William in the first year, but after two years in the loop, it is a very simple thing.

There are four crime scenes in the places that William knows now: the Defense Against the Dark Arts office, Snape's Potions Hut, the Ravenclaw Rest Gate, and the Room of Requirement.

He decided to be in the Defence Against the Dark Arts office, waiting for Tywin to show up.

This is where it all began.

Seven hundred and forty cycles.

Prepared for anything, William hid alone in a corner not far from Tywin's office.

It was only 7:40, the game hadn't started yet, and Tywin hadn't left the office.

After much observation, Tywin would leave in ten minutes, and William wasn't worried about him coming out at all.

William took the potion out of his robe and drank it in one gulp. It was an enhancer he had "taken" from Madam Pomfrey earlier.

To find out the truth, you must follow Tywin and know his every move.

William didn't want to be discovered, so he had to use the Transfiguration Charm.

However, the Illusion Charm is easy to discover by wizards with high mana, and William has thought of many ways to enhance the effect of the Illusion Charm, and he has found that in addition to long practice, only enhancers have an effect.

This special potion, which increases the effects of potions, is a precious medicine that Madam Pomfrey will only use during critical surgeries.

Similarly, this booster would also enhance the effects of the Transfiguration Charm, so that Tywin would not be able to spot William.

As for why William would know about this potion...... During one game, he fell from the sky and nearly separated his head and body, and Madam Pomfrey added the potion to improve the effect of the hemostat.

If there is any great gain from William in this time loop, it is that he has personally boiled most of the potions that appear in the textbook, and he has also tasted saltiness.

As soon as he smelled it, he noticed that the hemostatic smelled special, and after a long trial, he got the secret recipe from Madam Pomfrey.

After drinking the booster, William cast the Illusion Charm and stood quietly in the corner, holding a map of the living spots in his hand.

The next moment, four Tywins suddenly appeared on the map without warning!

One is in the Defense Against the Dark Arts office and is about to walk out the door.

One was in the hallway on the fourth floor, and he bumped into Dumbledore as he was exiting, and the two turned back to the third floor and walked into the Headmaster's office.

One is hidden in the corridor on the fifth floor.

A brisk walk to the promenade that leads to the Ravenclaw Tower.

"Four Tywin......" William shook his head, what a big deal!

Although it is not the first time to see this kind of scene, every time I see it, William feels wonderful.

William's task now is to solve the mystery of the four Tywins and find out why they are in all four places at the same time.

William didn't have time to think about it, and as the time arrived, the handle of the Defense Against the Dark Arts office was suddenly twisted away, and Tywin, who was hiding inside, walked out of the room on time, and every second was right.

He looked around vigilantly, and when he saw no one, he strode upstairs with his wand in his hand.

He was about to run into Tywin, who was hiding on the fifth floor.

William followed closely behind him, his heart beating as if it was about to fly out even after being sedative.

Fortunately, William's steps were light, and Tywin couldn't even notice that there was another person following him.

Around the corner on the fifth floor, Tywin is about to meet Tywin.

But to William's surprise, it was not Tywin who was hiding on the fifth floor, but Professor Snape.

Externally, he is indeed exactly the same as Snape, but his name on the map is still Tywin.

You can't go wrong with the map, and the other party should have taken the Polyjuice Decoction.

As a young wizard who had been taking Polyjuice Potion for a long time and mingling with two Quidditch teams, William knew Compound Potion too well.

But Tywin, who came out of the office, didn't seem to know that the guy in front of him was actually himself.

He had come to carry out a top-secret plan, and when he saw Snape appear in the hallway, he subconsciously thought he had been discovered.

"Snape" seemed to want to say something, but Tywin didn't think much of it, he raised his wand and shot out a spell.

"Snape" dodged sideways, and with his wand, he pointed forward from his shoulder, shouting, "Pass out!" ”

Tywin also had a magic shot and collided with him.

"Snape" appears to have suffered a serious injury before, his face is sallow, his body is full of wounds, and his reflexes are starting to be sluggish, so he is no match for Tywin.

After only a few rounds, a spell struck "Snape" in the chest, and his eyes widened in horror, and he was knocked straight into the air, slamming into the wall, and spitting a large pool of blood in his mouth.

Tywin grinned and stepped forward, as if trying to finish "Snape".

William looks like he's about to see Tywin kill Tywin!

But Snape's wand spun and landed on the pillars, and the walls collapsed, blocking the corridors on both sides.

Tywin didn't continue his pursuit, he watched through the gap and watched "Snape" staggering towards the stairs, he was silent for a moment, then made up his mind, and turned and ran towards the other side of the stairs.

Tywin quickened his pace, as if fearing that "Snape" would find Dumbledore and ruin his plans.

William also trotted up, and he looked at the map at the same time, and Tywin, who was using the Polyjuice Potion, did not go to Dumbledore's office, but ran towards the eighth floor.

He went to the Room of Requirement!

William finally knew why Tywin was no match for Lowe and how could he be the opponent of the three-headed dog with such a serious injury?

William didn't care about him, but continued to follow the Tywin in front of him.

Leaving the main building, there is a promenade, which is the shortest path leading to the Ravenclaw Tower.

William knew that there was also a "Tywin" waiting here.

Tywin walked down the corridor, perhaps because he was about to reach the Ravenclaw Tower, and his vigilance was lowered.

At that moment, a spell shot from the side without warning, grazing his head.

"Who is it?" Assaulted, Professor Tywin furious.

But "Tywin", who had been in ambush in the corridor for a long time, continued to cast the spell without heeding.

Tywin was caught off guard, especially when he saw that on the other side of the corridor, it was himself, he didn't know what was going on, and in a hurry, he was not an opponent.

Hit by another spell, he was slightly wounded, and then turned and ran.

"Tywin", who had been lying in ambush for a long time, smirked a few times, and turned and ran towards the Ravenclaw tower.

William knew that the other party was going to get the Ravenclaw ring, and after that, there was no more resistance, only Robert.

But instead of going to the Ravenclaw Tower, William continued to follow Tywin.

Tywin dragged his injured body to a corner, fumbling around the collar of his robe, pulling out a long, fine gold chain with a small gleaming gold needle hanging from underneath.

"Sure enough, it's this!"

William finally saw what he wanted to see, which is why Tywin could be in multiple places at once.

- Time Turner!

Professor Tywin twisted the time-turner counterclockwise, and he vanished in place.

Soon, all the rest of Tywin disappeared from the map of the living spots, like extinguished street lamps.

This means that Professor Tywin is dead.

William sat there and thought about it for a long time, and he finally understood the whole thing completely.

Totally understood.

It's so simple.

He could finally push the black-rimmed glasses that didn't exist on his face, and tell Dumbledore loudly:

"The new machine word digs one more Mo He!"
