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

They pushed the door open, the room was pitch black, and nothing could be seen.

But as soon as they stepped in, the house was suddenly brightly lit, illuminating a shocking scene.

They were standing on the edge of a huge wizard's chessboard, with black pieces in front of them. Those pieces were 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 you need us to play chess?" George frowned.

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

Cedric and William looked at each other, raised his eyebrows, and said with a smile, "It's undoubtedly Professor McGonagall's handwriting."

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

"Then who will come down?" Qiu asked.

"It's up to me." William said.

Several of them can play wizard chess, and Cedric was the best player in the past.

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

Cedric was no match for William since then.

What's more, William also studied for two weeks at St. Mungo's Magic Hospital and a three-time wizard chess champion, and his skills are invincible among his peers.

William knows several tricky routines, and he is best at Scottish opening and French defense.

However, here he is still going to choose Scotland to start, and the French defense sounds unlucky, giving people a feeling of bean curd engineering.

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

The rule for playing chess is that white moves first, and soon a white piece moves forward two squares.

William began to command Black's operations, and the others silently followed his orders.

William kept using the black queen to capture the opponent's pieces.

Every time, the black queen would viciously knock over the white chess piece on the floor, then drag the opponent's foot out of the chessboard, walk towards the corner, and come back after a while.

I don't know why, every time I see this situation, William feels weird, as if the king's head is green.

After playing for a while, William basically mastered the opponent's chess skills. It wasn't particularly high. As long as he had a slightly better level, he could defeat him.

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

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

They won, and the white pawns bowed and retreated to make way.

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

"What's the matter?" Cedric asked as he walked over to William.

"I'm thinking that these chess pieces... It should be more than just Professor McGonagall using Transfiguration."

William pointed to the chessboard.

"Transfiguration transforms an object, which requires wizard manipulation to move.

At this point, Professor McGonagall has already slept. Such a huge chess piece can not only move on its own, but also play chess with us on its own initiative... Just this, it is not something that Transfiguration can do. "

"what do you mean……"

"These chess pieces should be the product of Transfiguration and Alchemy.

I won't talk about Transfiguration, but the way alchemy works in it makes me curious. "William touched the white king.

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

In this regard, William is undoubtedly qualified.

If he also learns this alchemy technique, he can make a group of similar dolls to fight in his place.

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

Just like the Gringotts incident, William couldn't have waited for Nicknamel and Dumbledore's support every time.

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

"I remember." Hermione said suddenly: "It is recorded in "Hogwarts, A History" that there are a lot of statues and armors in this ancient castle.

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

William nodded and said with a smile, "Yes, that's a guardian magic called 'Shizhen Dispatch'. I think Professor McGonagall should have made some gadgets based on those things."

"So... what do you mean?"

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

They come here to take risks, naturally they want to get some benefits, can't they just come here in vain?

"After researching it, we can make a batch of powerful dolls, and we can all sell them." George laughed.

"What if Professor McGonagall finds out?" Hermione looked worried.

"Hermione, Professor Dumbledore has a deep meaning in everything he does.

Since he set up these levels, it is definitely not simple fun and interesting.

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

"That's right, all move away!" Qiu said seriously.

Hermione was speechless, she always thought these people were Gryffindors.

A few people hurriedly put the knocked out pieces in the pockets expanded by the Traceless Stretching Charm.

When William was leaving, he put the white king who had taken off his crown in.

Without King White, probably no one would be able to pass this chessboard and enter the door of the room.

Those chess pieces were all stupidly standing there. The order they received was to let the winner pass, but they didn't say that the winner couldn't move the pieces away.

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

What a miserable queen!

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

As William said, this is a level that has not been fully laid out, and there is also a lack of tools to catch the key at the previous key.

It seems that Dumbledore is still considering.

A few people opened the next door~lightnovelpub.net~ There is nothing scary here, just a table with seven bottles of different shapes arranged on it.

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

This flame is unusual, purple. At the same time, the door leading to the front also burst into black flames, 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've always liked bitterness before sweetness, bad news!" Fred said.

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

"What about the good news?"

"The flames are well controlled, and there is no tendency to get out of control. We are still safe."

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

William rolled his eyes.

"Do you think I am someone who can study black magic?"

"Yes!"

William suddenly smiled, seeing people too accurately!

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

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