Exchange student at Hogwarts

After entering the wooden door, the originally dark room suddenly became brightly lit. In front of them was a huge chessboard. They entered the area with black flags on one side and white chess pieces on the opposite side. All the chess pieces are made of marble-like material. The horses and knights are just like normal people, except that the knight's face is smooth and has no facial features.

"It seems that we are going to play chess instead of these black pieces." Everyone looked at Ron. Among the four, Ron was the only one who usually liked playing chess the most, and now they could only listen to his command.

"Harry, you be the bishop, Hermione you be the queen, Zhang you take the place of the castle, and I will be the knight." Ron finally met someone he was good at, and he was quite capable of commanding.

Those chess pieces seemed to be able to understand human speech. A bishop, a queen, a castle and a knight chess piece stepped off the chessboard in turn, giving up their positions to the four people.

The rules of wizard chess are somewhat similar to those of chess. The white pawn moves first. As soon as they stand still on the chessboard, the white pawn on the opposite side takes two steps forward.

Zhang Chen and the others also obeyed Ron's command. "It can't be a complete test of chess skills. Otherwise, I will try to see if I can attack the opponent's chess pieces from a distance." Zhang Chen placed all hope on Ron's chess skills. The level is very unsettling.

"No, let Ron try it first," Harry and Hermione stopped. "It will be more troublesome if these chess pieces are angered."

Under Ron's command, the black and white chess pieces were inextricably linked. Whenever a chess piece captured another, the chess pieces would knock it to the ground viciously and drag it outside the chessboard, which looked particularly special. Cruel and ruthless.

Soon, a large number of lifeless black and white chess pieces were scattered along the wall.

"Almost there," Ron whispered suddenly, "Let me think, let me think."

The White Queen turned her featureless face towards him.

"Yes..." Ron whispered, "This is the only way, I have to be eaten."

"No" Harry and Hermione shouted at the same time.

"This is chess," Ron said sharply, "There are always sacrifices to be made. If I take a step forward, she will eat me and you can checkmate the king, Harry."

"But"

"Do you want to stop Snape?"

"Ron"

"Hurry up, if you don't hurry up, he will already have the magic stone."

"I think" Zhang Chen had to interject, "this trap must have been designed by Professor McGonagall using the Transfiguration Technique. Based on my understanding of Professor McGonagall, she would not want to kill the person who broke into the formation. I guess The best I can do is to knock me out, or Ron, you can try and let me die."

"It can only be me, and I don't know what dangers there will be later. I can be sacrificed, but I can't do it without you in the team. But you are right, Zhang, I will be fine. Are you ready? I'm going."

He took a step forward, and the White Queen immediately pounced on him. She raised her stone arm and punched Ron so hard on the head that he fell to the floor. Hermione screamed but didn't move away from her plaid white queen and dragged Ron aside. It looked like Ron was knocked unconscious.

Trembling, Harry moved three spaces to the left.

The White King took the crown off his head and threw it at Harry's feet. They won. . The white pieces bowed and stepped back, making way for them to move toward the door smoothly.

Harry and Hermione looked back sadly at Ron for the last time, and then prepared to rush through the door and walk along the next corridor. When they walked outside the chessboard, they found that Zhang Chen had not followed.

Zhang Chen stood there and asked the king who had thrown away his crown: "I want to see if my companion is okay before I go over, is that okay?"

The king nodded silently, and suddenly a gap appeared on his face where his mouth should be, and he actually smiled.

Zhang Chen hurriedly ran to Ron to check his injuries and found that he had just fainted. He finally felt relieved and made an OK gesture. Then the two of them ducked and rushed to Harry and Hermione, joining them. Go down the next corridor.

"We have passed Sprout's mechanism, which is the devil's net. It must be Flitwick who enchanted those keys. Professor McGonagall deformed the chess pieces and made them come alive. Quirrell is left behind. , Snape's." Hermione speculated as she walked.

Soon they came to another door, and Harry pushed it open. A nauseatingly familiar odor hit his nostrils. It was a giant monster, even bigger than the one they fought last time. It lay motionless on the floor in front of them, unconscious, with a bloody head on its head. Large lump.

"Great, we don't have to fight this troll anymore," Harry whispered.Carefully they stepped over the troll's thick legs. "Come on, I can't breathe."

Opening the next door, the furnishings behind the door were pitiful and simple. There was nothing scary. There was only a table with seven bottles of different shapes arranged on it.

"Snape's magic," said Harry, "what should we do?"

As soon as the three of them crossed the threshold, a flame rose up behind them and sealed the doorway. The flame was unusual: it was purple. At the same time, black flames burst out from the door leading to the front. They're stuck in the middle.

There was a roll of parchment next to the bottle. "Danger is in front of you, safety is behind. There are two of us who can help you. Drink them, one will lead you forward, and the other will return you to where you came from. Two One contains nettle wine. Three are killers, waiting in line. Take your pick, unless you want to be stuck here forever. We also provide four clues to help you choose:

First, no matter how cunningly the poisons hide themselves, they actually stand to the left of the nettle wine;

Second, the contents of the bottles at the left and right ends are not comprehensive. If you want to move forward, they will not be useful to you;

Third, you’ll notice that the bottles come in all sizes. Death is not hidden among giants and dwarfs;

Fourth, the second one on the left and the second one on the right, although they look different, they taste the same. "

Seeing this, Zhang Chen and Hermione looked at each other and smiled, while Harry was confused and looked at the two of them in surprise, thinking that there was a three-seventh chance of drinking poison, if I couldn't laugh it off.

"Logic question, you or me?" Zhang Chen asked looking at Hermione.

"Give me a minute." Hermione read the paper a few more times. She walked up and down in front of the row of bottles, talking to herself and pointing to this or that bottle. Finally, she clapped her hands happily. "I know," she said, "this smallest bottle can help us get through the black flames to get the magic stone."

Harry looked at the small, inconspicuous bottle.

"There's not enough for two people to drink in it," he said. "It seems someone took a sip."

They look at each other.

"Which bottle can go back through the purple flames?" Harry asked again.

Hermione pointed to a round bottle on the far right.

"You two drink that bottle." Harry said, "You go back to find Ron and grab two broomsticks from the room with the flying keys. They will carry you through the trap door and go directly to the owls' shed. House, send Hedwig or Caesar to deliver a message to Dumbledore, we need his rescue. I may be able to temporarily contain Snape, but I am by no means his match."

"But Harry, what if the mysterious person is with him?" Hermione was a little scared.

"I'll go forward with you. You take a sip from the small bottle and I take half a sip. My mysterious power can resolve most of the fire damage." Zhang Chen said firmly, "If the mysterious person is inside You're going to die, Harry, and I can't let that happen."

"Zhang, meeting you is the luckiest thing in my life." Harry was so moved that he couldn't speak.

"Don't worry, I also discovered a problem. If this trap was designed by Snape, then whoever designed the troll trap just now will die faster if he doesn't even know who his opponent is." Zhang Chen He looked at Harry and said.

"It was Quirrell who was the troll he controlled. It was him that time at school. So why?" Harry and Hermione were both a little shocked.

"This is what I'm worried about. If it's Snape inside, he's probably alone. If it's Quirrell, he can't get through the previous levels with his strength, so I'm almost certain that Voldemort is with him. Inside, get ready Harry." Zhang Chen nodded and turned to signal Hermione to go first.

"I" Hermione looked at Zhang Chen and Harry, tears streaming down her face uncontrollably, "I just study hard and rely on a little cleverness. Other than that, I am useless."

"Hermione, you drink first," Harry said, "it's almost too late."

Hermione took a long drink from the round bottle on the right and shuddered all over.

"Isn't it poison?" Harry asked worriedly.

"No but like ice, bitingly cold."

"Come on!" Hermione turned around and walked straight through the purple flames.

Harry took a deep breath and grabbed the smallest bottle.He turned to face the black flames.

"Drink more, don't leave too much for me, I know it well," Zhang Chen encouraged.

"I'm here." After he finished speaking, he drank most of the liquid in the small bottle in one sip. After drinking, he handed the bottle to Zhang Chen, who raised his head and drank.

It literally penetrated their entire bodies like ice. The two of them rushed towards the black flames side by side. Harry rushed over without feeling anything. After entering, he quickly looked at Zhang Chen. He was fighting the remaining fire on his robe. Although there were some burn marks on his body, he was not seriously injured. .

After entering the door, there was another huge hall, and there was already a person in it. It was not Snape, not even Voldemort, it was the Quirrell that Zhang Chen guessed.

"It's you" Harry gasped in shock.

Quirrell smiled, his face no longer twitching at all now, "It's me. I was just wondering if I would meet you here, Potter."

"But I thought..."

"You thought it was Snape" Quirrell laughed. This laugh was not his usual high-pitched trill, but a chilling sneer. "Yes, Snape does not look like a good person, does he? He flies around like a giant bat, which is very helpful to us. With him there, who would doubt it~ But ~Poor, stammering Professor Quirrell~"

"But Snape tried to kill me during the Quidditch match."

"No, no, no, it was me who wanted to kill you. During that Quidditch match, your friend Miss Granger rushed over to cast a spell on Snape and accidentally knocked me down. She destroyed In fact, as long as I hold on for a few more seconds, I will throw you off the broomstick. If Snape hadn't been chanting a protective spell beside you to save your life, I would have thrown you off the broomstick. You fell to death."

"Ahem, let me add, even if you fall, you won't die. Do you think I gave it to you for free?" Zhang Chen was a little dissatisfied that he was ignored. The dual-core promised, but how come it became four guarantees and one guarantee?

"Snape wanted to save me" Harry still couldn't believe Quirrell's answer.

"Of course it is," Quirrell said coldly, "Why did he want to referee your second match? He wanted to make sure I didn't hurt you again. It's ridiculous. In fact, he didn't need to bother. With Deng There was nothing I could do with Bullydo present. The other teachers thought Snape was trying to prevent Gryffindor from winning, and he did make himself very unpopular. But it was all a waste of time, anyway. , I must kill you tonight. And of course the Oriental boy next to you," Quirrell said viciously.

"A brief introduction, my name is Zhang Chen, Kunlun sword cultivator." Zhang Chen made a gesture and put on a pose that he thought was cool to show respect for the villain.

"Damn Dongfang boy, last time in the Forbidden Forest, you dared to hurt the possessed body of the supreme Dark Lord. You will die a good death." Quirrell stared at Zhang Chen, wishing he could eat him.

"So what appeared in the Forbidden Forest that day was really Voldemort, who was not very powerful at all," Zhang Chen said with disdain.

Quirrell looked at Zhang Chen like a clown: "What do you know? When the Dark Lord ruled the entire magical world, you were not even born yet, a mudblood from the East." After speaking, he snapped his fingers and said that it was a long time ago. Soon, several ropes suddenly appeared out of thin air, trying to tie up Zhang Chen and Harry.

Harry was unprepared and was trapped. Zhang Chen had been on the highest alert since he entered the room. When he saw the rope, he dodged and escaped from being tied up. However, more and more ropes appeared in the air, and they continued to flow. It didn't take long for Zhang Chen to be caught up by the rope, and Biha was wrapped around him. The rope, which was nearly five times more powerful, was completely tied into a mummy. Once tied up with the rope, Zhang Chen found that all his consciousness was compressed on the body surface, and he completely lost control of the divine source outside his body. It seems that this spell also has the effect of banning demons.

"You guys are too nosy, and I can't let you live in the world anymore. On Halloween, you were wandering around in the school. I knew at that time that it would definitely be you who would ruin my affairs, especially you, an oriental boy, actually Damn it for defeating a troll.”

"You were the one who let that troll in."

"Of course it is. I almost succeeded on Halloween. Unfortunately, when everyone was hurriedly looking for trolls, Snape, who had already been suspicious of me, rushed directly to the fourth floor and tried to stop me. Not only did I The troll didn't kill you, and even the big three-headed dog didn't bite Snape's leg off.

"Okay, wait quietly, you two little bastards. I need to take a closer look at this interesting mirror. When I get the magic stone, you will die."

Only then did the two of them notice that standing in the center of the hall was the Mirror of Erised.

Quirrell kept studying around the Mirror of Erised, while Harry talked to him desperately, trying to distract him. He also learned from Quirrell about the grievances between Snape and Harry's father.

Just when Harry was trying his best to interfere with Quirrell, Zhang Chen's voice suddenly came from his ears: "Harry, stay normal, only you can hear what I'm saying now. This is a skill from the East called teleportation." "The sound is secret"

Harry was stunned for a moment, then immediately adjusted and continued chatting with Quirrell.

"I'm sure to break free from the rope at any time, but I don't know what other means Voldemort has. You'll have to attract his attention later and make him come as close to me as possible. I'll take action instantly. I won't kill him but I'll injure him severely. "Seeing that Zhang Chen couldn't wait any longer, he could only arrange a plan to swallow the jujube in full.

Harry nodded while Quirrell's back was turned to them, and chatted harder with Quirrell.

A few more minutes passed, but Quirrell still couldn't find the secret hidden in the Mirror of Erised. "What's going on with this mirror? What function does it have? Help me, Master!" Quirrell shouted helplessly into the air. At this moment, Harry heard another voice replying in horror. The voice seemed to be Ventriloquism emanating from Quirrell himself. "Use that boy...use that boy..."

Quirrell turned to Harry. "Okay, Potter, come up here."

He clapped his hands together again, and the ropes that bound Harry loosened automatically. Harry stood up slowly. "Come up here," repeated Quirrell, "look in the mirror, and tell me what you see."

Harry obeyed and walked towards the mirror.

This time, Harry only saw himself in the mirror. At first, his face was pale and he looked terrified, but after a moment, Harry in the mirror showed a mischievous smile. He reached into his pocket and pulled out a bright red stone, then blinked and put the stone back into his pocket. At this moment, Harry felt that something heavy had really fallen into his pocket. It's incredible that he actually got the Philosopher's Stone like this.

"What did you see?" Quirrell felt Harry's expression was different.

"I saw myself shaking Dumbledore's hand," Harry made up, "I won the House Cup for Gryffindor."

"He lied. Let me talk to him, face to face." The hoarse voice came out again, and Harry seemed to be swallowed up by fear and did not dare to move.

Quirrell raised his hand and took off the scarf from his head, and then he slowly turned around. Where the back of Quirrell's head should have been, there was a face. What a hideous and terrifying face it was. The color of the face was as dead as chalk, with bright red eyes and two slender nostrils like snakes underneath.

"Harry Potter," he whispered.

Harry tried to step back, but his legs wouldn't work.

"Look what I have become," said the face. "Only shadow and vapor remain. I can only have form when I share a body with others, but there are always some people who are willing to let me into their bodies." Heart and mind. In the past few weeks, the blood of unicorns has allowed me to regain some strength. That day you saw me in the forest possessing a python and drinking blood. The nasty oriental boy injured me. Originally I can be stronger. But it doesn't matter. Once I get the elixir, I can recreate my own body. Well, Harry Potter, why don't you give me the Philosopher's Stone in your pocket? "

Turns out he knew Harry had suddenly regained feeling in his legs. He staggered back.

"Don't be stupid," the face said viciously, "It's best to save your own life and take refuge in me, otherwise you will end up like your parents... They begged me for mercy before they died. "

"Lie" Harry shouted sharply.

Quirrell stepped back towards him, allowing Voldemort to still stare at him.Now there was a grin on that wicked face.

Harry gradually retreated behind Zhang Chen, and Voldemort also walked to a position parallel to Zhang Chen. "You run towards the black flames and pretend to want to escape back." Zhang Chen continued to use voice transmission to guide Harry to create opportunities, and Harry rushed towards the door burning with black flames. Voldemort screamed "Get it", and Quirrell desperately stretched out his hand to grab Harry.

At this moment, a brilliant sword light spread out from under Zhang Chen's robe. It turned out that Zhang Chen had already used Xuan Gong to get rid of the restrictions of the rope. Using the magic wand as a sword, he used the most powerful sky-skimming move in the Qinglian Sword Code, silver and white. The sword energy was like the Milky Way hanging down from the sky. It struck Chilo straight down, diagonally downward from his left shoulder, almost splitting his entire body in half.

"Ahhhhhhhhhh" Quirrell and Voldemort screamed at the same time. A black light flew out from under Quirrell's robe and struck Zhang Chen who was exhausted, knocking him back more than ten meters. For a moment, Zhang Chen only felt that countless desires and demonic energy invaded his sea of ​​consciousness, constantly destroying his spiritual consciousness. He quickly took out a handful of Pure Heart Demon Control Pill and ate it. He managed to get up and meditate, using the Qinglian Sword Qi to protect his mind.

On the other side, Quirrell was suddenly severely injured. A sharp sword mark was cut from his left shoulder to his right. Blood sprayed out from the wound as if it was free and splashed all over Harry's face. Quirrell made a sharp move with his right hand, and the scarf he had just taken off flew to barely cover his body, but Harry seemed to be frightened by the blood splattering in the sky and remained motionless.

After simply fixing his body, Quirrell pounced forward, knocked Harry to the ground, sat on him, strangled Harry's neck with both hands, and neighed "ho ho" from his mouth. He knew that only the Philosopher's Stone was there now. Only then can he save his life. Harry felt intense burning heat radiating from the wound on his forehead, and his whole head buzzed with pain. He only heard the sound of "chichichi" in his ears. Quirrell's hand pinched Harry's hand, which seemed to be burned by flames and turned black. ,gasification.

At this time, Zhang Chen barely suppressed the demonic energy in the sea of ​​consciousness and shouted to Harry, "Throw the magic stone over and let him come to me."

Harry resisted the severe pain of the scar on his forehead, reached into his jacket pocket, took out the magic stone, and threw it to Zhang Chen. After Zhang Chen received it, he used Qinggong and quickly ran to another corner of the room.

"Use magic, you idiot," Voldemort roared. Quirrell let go of Harry, turned around and took out his wand, and shot curses at Zhang Chen with green, red, and black light.

Zhang Chen forcibly suppressed the turmoil in his mind, and kept using his body skills to dodge Quirrell's various magics. The early sparring with Hermione and the others in the Room of Requirement worked wonders. Zhang Chen was like a raindrop under the bombardment of Quirrell's spells. Duckweed, although seemingly shaky, was actually very safe. While avoiding magic, he could occasionally send out a few sword energy counterattacks, leaving Quirrell in a state of embarrassment.

"Kill Harry first" Voldemort was furious as he saw that Zhang Chen could not do anything for the time being. Quirrell raised his hand, preparing to cast a killing curse. Out of instinct, Harry rushed forward and raised his hand to grab Quirrell's face.

“Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh” smoke curled up from the place where Harry touched Quirrell’s face, and Harry suddenly realized that as long as he touched Quirrell’s exposed skin, it would burn him. Harry jumped up, grabbed Quirrell's arm, and refused to let go. Quirrell screamed and tried desperately to get rid of Harry. Harry's headache became more and more severe, making his eyes black and he couldn't think of anything. He could only hear Quirrell's terrifying screams and Voldemort. Roaring viciously.

Suddenly, he felt his hands loosen, his thoughts were over, and he was broken free. Then his mind could no longer hold on, and he sank into darkness and passed out.
