"Okay!" As he spoke, Harry lit the light with his wand and went down the ladder, and after the three of them went down, Zhang Xuan followed closely behind.

"This room is pitch black, and the floor is very soft!" Hermione whispered, involuntarily approaching Zhang Xuan,

Zhang Xuan said: "This light is so small that I can't even see the floor clearly!" Look at me, illumination! ”

With a wand click, the room was as bright as day, and everyone realized that there was a layer of plant roots on the ground.

The black roots were like snakes, causing several people to jump around.

"Ah, it's disgusting!" Ron shouted, but the tendrils suddenly wriggled and instantly entangled several people, and the more they struggled, the tighter they became.

"Relax and don't struggle!" Hermione shouted, "This is the devil's net, as long as it doesn't move, it's fine!" ”

With that, Harry and Hermione relaxed, and the whole person slid underneath.

Zhang Xuan had already relaxed, and fell down together, and Ron above shouted in shock when he saw Zhang Xuan and several people being devoured by the devil's net:

"Zhang Xuan, Harry, Hermione! Where are you? Let me go, I'm going to save them! ”

Zhang Xuan, Harry, and Hermione glanced at each other, but they didn't expect Ron to still think about them at this time, and his heart was also warm.

Zhang Xuan shook his head: the wand said, "The flames are coming!" ”

In addition to the fact that this devil's net will not prey on you if it does not move, there is also a fear of fire, which is also one of the weaknesses of all plants!

Zhang Xuan's flame pointed out, and those devil nets shrank separately, and after a while, they saw Ron screaming and falling!

"Ah~~! Oops! ”

Ron screamed and fell to the floor, and it took a while to recover and see Zhang Xuan and the three staring at him with smiles, and Ron also blushed.

"You already knew how to use fire, why do you still see me being entangled!" Saying that, Ron stood up and rubbed it in an angry manner, it was not light to fall down just now!

"I said don't move, you don't listen!" Hermione laughed, "Are you alright?" ”

Ron was also ashamed, and waved his hand: "It's okay, it's okay!" ”

"Looks like Snape has seized his chance this time!" Harry said, "I heard from Hagrid that this Philosopher's Stone was protected by a mechanism set up by the professors of the school, and he must have figured out how to crack it before he took it!" ”

"Looks like we're going to have to pick things up!" Ron said, and several people hurriedly walked forward, and suddenly heard a lot of flapping wings in front of them.

"Look, it's a lot of birds!" Ron exclaimed,

Zhang Xuan shook his head and said, "No, you take a closer look, those things have a key to wings!" ”

"That means we need to grab the key and open the door!" Hermione said.

As she spoke, she looked around the room and found a few brooms, and Hermione said, "Looks like this is our test!" ”

"But how many keys there are, which one is real!" Ron said with a bitter face.

There are thousands of keys in this room, and they are still flying, and the devil knows which one is real!

"It should be the same color as the doorknob, a silver key." Zhang Xuan smiled, "I think, Harry, it's your turn to behave!" ”

"That's a good point!" Harry immediately rode his broom and searched the room for his silver key.

And Zhang Xuan's spirit had already secretly dispersed, and he immediately found that there was an area in the room that was blank.

It's like encountering an obstacle in the water waves, and it is impossible to detect the abnormality, but it is this seemingly carefree blank that shows that there is a person hidden there.

Hehe, Dumbledore, it's you, you deliberately did such a little trick, you are really patient! Zhang Xuan smiled in his heart: You really have time to spare.

In a few moments, Harry grabbed the silver key and opened the door, which was followed by a chessboard.

"Hey, it's wizard chess!" Ron exclaimed, "It's so big, it's all made of stone!" ”

Harry hurried over and found the door blocked by the Queen.

"This queen can't push it!" Harry exclaimed, pushing hard a few more times, but not moving.

"No, there are four missing pieces of black here, I think we should play chess!" Ron hesitated,

Harry hurriedly said, "Then let's try it!" ”

Zhang Xuan laughed in his heart, this Dumbledore, Dumbledore, is it really useful for you to do this with such a deliberate effort? You've worked hard to train Harry!

"Zhang Xuan, Harry, Hermione, you all stand up, I'm going to start playing chess!" Ron shouted, and as he spoke, the crowd began to move according to Ron's arrangement.

I saw that as the two sides fought, these stone statues were also smashed to pieces, making several children frightened, and finally Ron had to go up alone and be beaten, ready to sacrifice himself to complete the victory.

"There always be sacrifices, don't you?" Ron stepped forward with a smile, ready to let the white queen hit with a stick.

Zhang Xuan shook his head and said, "Ron, I didn't expect you to have such courage to deliberately sacrifice yourself so that we were unharmed!" ”

"You are all my friends, how could I be willing to let you get hurt!" With that, Ron stepped forward, and the white queen struck with a cane.

Zhang Xuan was a little wand: "Levitation!" Ron flew up in an instant, narrowly avoiding the blow,

"Harry, you can be a general!" Zhang Xuandao.

Harry hadn't yet reacted from the tragedy just now, and listened to Zhang Xuan's command to take a step forward, and then took the white chess army, and the door opened.

"Alright! We can go in! Zhang Xuan smiled,

"Oh, yes!" Harry replied.

"Put me down, I'm going too!" Ron, who was floating in the air, shouted.

"I almost forgot!" Zhang Xuan shook his head, Harry and Hermione also covered their mouths and snickered, the sadness and tragedy just now were swept away, and the four of them entered the room inside.

There were only seven bottles of potion on the table, and a note,

"Oh my God, it's so complicated, a return potion, a forward potion, three poison wine, two ordinary wine, how can this be calculated!" Ron said, grabbing his hair.

It seems that Snape did the level this time, but I didn't expect him to like this kind of small reasoning problem.

"It's not too hard!" Hermione said, "According to the hint on the note, the smallest bottle is the wine for the advance!" ”

"But that's enough for one person to drink!" Harry Drive,

Zhang Xuan smiled: "It's okay, it just so happens that you gave me Floo Fan today, but you can increase it a little." ”

Saying that, Zhang Xuan took out the two bottles of nettle wine on the table, mixed them with the advance wine and the Floo powder, and fused them together and said, "That's it, we can all move forward!" ”

With that, they drank the potion and entered the next room through the black flame door.

The room was brightly lit, and a black figure stood in front of the mirror pacing back and forth.
