Hermione took the key and stuffed it into the keyhole, twisted it hard, and with a click, the door lock bounced open.

They pushed the door open, and the room was pitch black and there was nothing to see.

But when they stepped in, the room suddenly became brightly lit, illuminating a shocking scene.

They stood beside a huge wizard board, with black chess pieces in front of them, all taller than them, and seemed to be carved from black stones or something.

At the other end of the room, facing them were some white chess pieces.

"Do we need to play chess?" George frowned.

"It should be, probably as long as you win, the door to the opposite room will open." Fred nodded.

Cedric and William looked at each other, raised their eyebrows and smiled, "It was undoubtedly Professor McGonagall's work."

William shrugged, "Professor McGonagall, you can always come up with some new tricks."

"Who will come down?" Qiu asked.

"I'll do it." William said.

Several of them could play wizard chess, and Cedric, the one who played the best in the past, was the best.

However, since William has been in the time loop for two years, he has been idle for a while and is specializing in finding someone to play wizard chess.

Cedric has been no match for William since then.

What's more, William also studied at St. Mungo Magic Hospital and the three-time Wizard Chess Championship for two weeks, and his skills were invincible among his peers.

William knew several tricky routines, and he was best at the start of Scotland and France's defense.

However, he is still preparing to start here with Scotland. France's defense sounds not very good, giving people a feeling of shoddy projects.

William and his men replaced the six pieces and stood on the chessboard. The six pieces that left turned around, turned their backs to the white pieces, walked out of the chessboard, and stood in the distance to watch the battle.?

The rule of playing chess is to move first in white chess first, and soon a white chess piece moved forward two grids.

?William began to command the black chess battle, while the others silently obeyed his orders.

William kept using the Black Queen to eat the other party's pawns.

Every time, the Black Queen would fiercely knock the white chess over the floor, then drag the other person's feet out of the board, walk towards the corner, and after a while, she would come back.

For some reason, every time I see this situation, William feels strange, as if the king's head is green.

After playing for a while, William basically mastered the opponent's chess power. It was not particularly high. Anyone with a slightly better level could defeat him.

Yes, if the opponent is AlphaGo's level of artificial intelligence, William would tremble and weakly say: "I can't do it, I can't do it, I can't win, I really can't win."

When William commanded the knights to stand in front of King White, the White took off the crown on his head and threw it at William's feet.

They won, and the white chess pieces bowed and retreated one after another to give way out.

But William did not leave immediately, but continued to observe the pieces.

"What's wrong?" Cedric asked when he walked to William.

"I was thinking that these pieces... should be more than just Professor McGonagall used the transformation."

William pointed at the chessboard.

"The Transformation transforms an object, and it takes a wizard to operate it.

Professor McGonagall has already slept. Such a huge piece can not only move on its own, but also play chess with us on its own... This alone is not something that can be done by the transformation technique."

"you mean……"

“These pieces should be the product of transformation and alchemy.

I won’t talk about the Transformation. The way the alchemy used in it makes me curious.” William touched the White King.

Always be curious about what you don't know, this is a Ravenclaw.

William is undoubtedly qualified in this regard.

If he also learned this alchemy technique, he could make a batch of similar dolls to fight on his behalf.

The magic world is undoubtedly dangerous, and it is always right to increase the combat power.

For example, in the Gringott incident, William could not have waited for Nicklemay and Dumbledore's support every time.

A wizard is truly powerful if he is strong, and alchemy is also one of them.

"I remember," Hermione said suddenly: "In "Hogwarts, A History", this ancient castle contains a large number of statues and armor.

These things have been silent in the corners. When the ancient castle of Hogwarts is attacked, they will wake up, accept the principal's instructions, guard the castle, defend the students, and fulfill their obligations for the school!"

William nodded and smiled, "That's right, that's a guardian magic called 'Stone Hood'. I think Professor McGonagall should have made some gadgets based on those things."

"So...what do you mean?"

William smiled, not only him, Fred, George and Cedric all laughed.

They come here to take risks, so they naturally have to get some benefits. They can't come here for a while, right?

"After researching it, we can make a batch of powerful figures that we can all sell." George laughed.

"What if Professor McGonagall finds out?" Hermione showed a worried look.

“Professor Dumbledore does everything with a deep meaning.

Since he sets these levels, it is definitely not simple, fun or fun.

I guess he wants to train the little wizard and let us learn more. We are learning, these pieces are."

"Yes, move them all away!" Qiu said seriously.

Hermione was speechless. She always felt that these people were Gryffindor.

Several people were in a hurry to put the knocked chess pieces in their pockets with the expanded Stretching Spell.

When William left, he even put the White King who had taken off his crown in it.

Without the White King, probably no one could enter the room door through this chessboard.

The chess pieces stood foolishly, and they accepted the instructions to let the winner pass, but they did not say that the winner could not move the chess pieces away.

The Black Queen stood alone, watching William and others leave with an expressionless face.

What a miserable queen!

Soon, they walked into the next room, but there was nothing inside.

As William said, this is a level that has not been fully arranged, and the key grabbing tools are missing at the previous key.

It seems Dumbledore is still thinking about it.

The few people opened the next door again, and there was nothing scary here, only a table, with seven bottles of different shapes on it.

As soon as William and the others crossed the threshold, a flame rose from behind and sealed the door.

The flame was unusual and purple. At the same time, black flames also popped up at the door leading to the front, and they were trapped in the middle.?

"Ah Ou, there is good news and bad news. Which one are you going to listen to first?" William stared at the black fire.

"I always like to be bitter first and then sweet, bad news!" Fred said.

"The bad news is... this is the devil's flame, a kind of black magic, extremely dangerous, and you will die if you touch it."

“What about good news?”

"This flame is well controlled, there is no trend of losing control at present, so we are still safe."

George shrugged, "What good news is that, I thought you would say you could control this flame."

William rolled his eyes.

"Do you think I'm a person who can study black magic?"

"yes!"

William suddenly smiled and looked at people too accurately!

Although he has not studied it now, he will definitely study it in the future.

Every magic master is also a dark magic master, including Dumbledore and Professor Flevy.
