Exchange student at Hogwarts

The place where the decoction was prepared was finally chosen to be the women's bathroom on the first floor of the basement. Due to Crying Myrtle, almost no one would set foot there. Hermione would come to brew the polyjuice potion after class every day, and would constantly put the herbs collected by Zhang Chen and Harry into the crucible. Zhang Chen and the others used almost all the connections at their disposal, and even asked for help. Nick, who was almost headless, had just collected most of the ingredients needed for the potion, and he was still missing the last two ingredients: the horn of a bicorn and the skin of an African tree snake.

"I think these two materials can only be found in Snape's medicine cabinet, and they are definitely impossible to find elsewhere." Harry lowered his head in frustration. In its opinion, it was simply too easy to throw materials from Snape's medicine cabinet. It was an impossible task, and he would rather face Slytherin's magical monsters than be caught by Snape stealing something from Snape's office.

"There is a military book in ancient China called Sun Tzu's Art of War, and there is a plan in it called "Toilet from the east and attack from the west." Zhang Chen decided, "Harry and Ron attracted Snape's attention in the classroom, and Hermione and I went to his office to steal materials."

"Why is Hermione going? This kind of thing is too dangerous, so I should go." Ron suddenly became a gentleman, which made everyone uncomfortable.

"The question is, can you identify the two materials that need to be stolen?" Harry teased unceremoniously. Hermione also looked at Ron with a smile. Ron stared, with a confused look on his big nose.

"You'd better give us ten minutes. His medicine cabinet must have early warning magic, and maybe even destructive magic. I'll be responsible for getting it then, and Hermione, you'll be responsible for telling me which two to get." Zhang Chen looked very Dignified, because only he knew how powerful a potions master Snape was.

Potions lessons were held in a large underground classroom. Thursday afternoon class started as usual. Twenty crucibles stood between the wooden tables. On the table were copper scales and jars of ingredients. Snape walked back and forth in a cloud of smoke, rudely criticizing the work of the Gryffindor students, while the Slytherin students gloated and snickered. Draco Malfoy, Snape's protege, kept rolling his goldfish eyes at Ron and Harry. Ron and Harry knew that if they responded with an eye for an eye, they would be imprisoned immediately without even being able to say "Unjust".

Harry's swelling potion was too dilute and his mind was focused on more important things. He was waiting for a signal from Hermione, and was barely paying attention when Snape stopped to laugh at his watery soup. Snape turned around and went to bully Neville. Hermione caught Harry's gaze and nodded. Harry quickly ducked behind his cauldron, pulled out a string of Fred's hard-drawn sparklers from his pocket, and clicked them quickly with his wand. Fireworks began to hiss, sparks flying in and out. Knowing he only had a few seconds, Harry straightened up, took aim, and threw the firework. The firework fell accurately into Gower's pot.

Gore's potion exploded and poured onto the entire class. Everyone screamed under the attack of the splashing swelling potion. Malfoy was doused in the face and his nose swelled up like a balloon; Goyle stumbled around with his hands over his eyes, his eyes swollen as big as lunch plates. Snape tried desperately to silence everyone and figure out what was going on. In the chaos, Harry saw Zhang Chen and Hermione sneaking out of the classroom.

Standing in front of the medicine cabinet in Snape's office, Zhang Chen motioned to Hermione to take a few steps back, then took out the iron hook made of a clothes rack that he had prepared earlier, opened the cabinet door suddenly, and then dodged to avoid the front. .

The moment the cabinet door opened, a burst of dark green smoke suddenly spurted out, covering the entire fan-shaped area within three meters in front of the door. The iron coat hook hanging on the door handle was corroded to pieces in an instant. Zhang Chen and Hermione were shocked.

"Quickly tell me which two they are," Zhang Chen urged while wearing dragon leather gloves.

"The third one in the first row and the second one in the fifth row."

Zhang Chen reached into two jars containing medicinal materials without hesitation, and took out the horn of a bicorn and the skin of an African tree snake. Just when he was about to pull his hand away from the medicine cabinet, a puff of black smoke came out of the medicine cabinet. The wooden boards on both sides of the cabinet door jumped out, forming the shape of a hand, and grabbed Zhang Chen's arm.

The black smoke was obviously corrosive. It corroded the long-distance running sleeves in a second or two, and made a sizzling sound on Zhang Chen's skin. Zhang Chen tried to break away twice without success. It was obvious that this black smoke was not an ordinary spell.

Just when Hermione next to her was anxious and didn't know what to do, Zhang Chen's staff floated out from the hem pocket of his robe and pointed at the two black smoke claws, the "extreme cold ray" taught by Dumbledore The magic is indeed extraordinary, even if it is not physical, the black smoke claw is still frozen. At this time, Zhang Chen struggled hard again, and his frozen claws fell to the ground in pieces.

Ten minutes later, everyone gathered in Moaning Myrtle's bathroom.

"I have a feeling Snape knows it was me," Harry said quietly.

"But he has no proof," Ron reassured Harry.

"I feel that if the two black claw marks on my arm are not removed as soon as possible, he will have evidence soon." Zhang Chen endured the burning pain on his arm and continued to wrap it with the ice air of the ice ray. Cover the wound.

"What should I do? What kind of spell is this?" Harry and Ron covered their eyes in disgust when they saw Zhang Chen's forearm, which was corroded and bloody.

"Huh, let's try Xuan Gong. A dead horse is treated like a living horse doctor." Zhang Chen first swallowed two Qingxinjiedu pills to suppress the spread of black energy, and then continued to display the key points of the Seven Birds and Five Beasts training. Physical skills, combined with the Qi Guiding Tips of Xuan Gong, constantly guide the Qi to attack the opening of the forearm.

On the other side, Hermione saw that Zhang Chen barely controlled the spread of the wound, and felt relieved. Then she remembered her mission, hurriedly threw the herbs into the crucible, and stirred vigorously. "It'll be ready in two weeks."

"Okay, you guys just watch the fire here, I have to go to the Room of Requirement." Zhang Chen tried a few times, knowing that now his cultivation level can only barely control the wound from getting worse. If he wants to heal the wound as soon as possible, he can only think Methods to further enhance the realm of Xuan Gong.

First, he went upstairs to get a First Turn Golden Pill and a few Pure Heart Demon Control Pills. Zhang Chen took three steps at a time and ran to the Room of Requirement, imagining an empty room suitable for retreat.

In fact, Zhang Chen's Xuan Gong has stayed at the top of the second level for a long time, and he can break through to the third level long ago. However, after he started school, he became addicted to the practice of magic, which caused the progress of Qinglian Sword Code to be delayed and still lingering in the middle of the second level of foundation building. Because he was afraid of problems caused by the mismatch between realm and mental cultivation, Zhang Chen never passed the test. But this time it is impossible not to pass the test. There is only one level difference between the two realms, so it should not be a big problem.

After making all preparations, Zhang Chen swallowed the Golden Pill and the Pure Heart Demon Control Pill and officially started to break through the barrier.

Xuan Gong is the supreme Xuan Gong that can transform the body into a god. Its cultivation and breakthrough are very different from normal exercises. In the entire stage of refining and refining the Qi, the most important thing to focus on is the accumulation of the physical body, including the Golden Elixir, Nascent Soul, and Yuanshen. As long as the strength reaches the standard, breaking through is just a matter of course. Zhang Chen has encountered many adventures since he started practicing Xuan Gong. Not only did he learn how to transform his physical body in advance by learning from the magic of transformation, but also because of the magic stone and the union of divine energy and the practice of the Three Yuan Hammer, his physical body had already reached the limit of the foundation building period. , breaking the barrier is just an ordinary thing.

Not long after taking the elixir, Zhang Chen's true energy circulated for eighteen weeks according to the route of movement. It entered Jueyin Shu through Fengmen, then went straight down through Du Shu, breaking through the Danshu, Stomach, and Shenshu points, and arrived at Huiyang again. Returning, dozens of times, he suddenly heard a "pop" sound in his body, like the sound of a small bubble bursting, but Zhang Chen's ears felt like the roar of a plane passing by, and the energy and blood in his body continued to surge.

He couldn't help the rush of energy and blood, so he turned over and lay down. His muscles continued to squirm, and he slowly turned into the shape of a mouse. However, the mouse that had changed at this time was no longer the ordinary little black mouse it had become before, but was instead brown and yellow. , its body is nearly five times the size of a small black mouse, and its feet will sink slightly when it steps on the ground. It actually brings its own soil to escape Shentong. After a while, the ups and downs of Zhang Chen's body completely calmed down. He also regained his consciousness and took the time to examine his own changes.

"Treasure-hunting rat returns to its ancestors. It would be too laborious if you had to learn each transformation one by one. It turns out that Xuan Gong can trace the bloodline of ancient mythical beasts online based on genetic fragments. It is really very practical." Zhang Chen studied it. It took him a long time to understand that due to the improvement of his realm, his power of change can continuously trace back to the original existence. The treasure-hunting rat is the remnant of an ancient mythical beast. The first ancient treasure-hunting rat when the world first opened was Taoist Duobao, the senior brother of Jiejiao. Of course, the treasure-hunting rat that Zhang Chen has returned to his ancestors is just a very ordinary treasure-hunting rat. It is not the same as the ancient power, but even so, it has two magical powers. One is the earth escape technique, which can travel within the earth system at will. The second is super-sensitive perception, which can sense treasures within a certain range and dangers within a certain range. The principle is mysterious and the effect is miraculous.

After adapting to the changes in his body, Zhang Chen returned to his human form and continued to explore the mysteries of Xuan Gong. First, the strength has been greatly enhanced, and no traces of the previous injuries can be seen at all; second, the ability to change is more flexible, and ordinary mice can change almost at will, becoming an instant skill. In addition, a scroll similar to a talent map appears in the sea of ​​​​consciousness. It shows in detail the changing directions of almost all rats, but only one upward vertical line is lit, and the two bottom ones on the vertical line are lit. The small dots shone brightly, and when you focused your attention, you saw that they were two changes between ordinary mice and treasure-hunting mice. Above the treasure-hunting mice, there is also a mole rat, which looks like a dog and has a keen sense of smell, as well as a sniper, with white ears and a white beak. His country has a large army. The rat and the sniper are both exotic animals recorded in the Classic of Mountains and Seas. Zhang Chen discovered that as long as he devoted his energy to study, he could even learn all the changes of rats through this map.

Although the art of change has made great progress, the three heads and six arms, the three heads and six arms, the magic of the sky and the earth, and the mustard seeds that Zhang Chen has been thinking about are still missing, which makes him depressed for a long time. But there is good news. It may be that the gap between Qinglian Sword Code and Xuan Gong is not big, and there is no mismatch between mind and spirit. Zhang Chen only had a few simple exercises and was able to perfectly control the surge in power.

Just a few words here, it was actually a day later when Zhang Chen came out of seclusion. After he returned to the dormitory, everyone felt relieved when they saw that he was unharmed and started chatting about a major event that had just happened today.

"What is this Duel Club?"

"It's our first party tonight, you'll know if you attend it." Harry and Ron looked excited, while Hermione looked uninterested, obviously still intoxicated in the preparation of the compound potion.

At eight o'clock in the evening, after dinner, the long dining table in the auditorium disappeared, and a gilded stage appeared along one wall, lit by hundreds of candles floating in the sky. The ceiling became as dark as velvet again, and almost all the students from the school were here, crowded together, everyone holding their own wands, their faces full of excitement.

"I wonder who will teach us," Hermione said as they squeezed into the chattering crowd. "Someone told me that Flitwick was a dueling champion when he was young. Maybe he will teach us."

"As long as it's not oh no~~" Harry didn't finish his words and turned into a groan. Gilderoy Lockhart walked onto the stage, wearing a purple robe, dazzling. The person beside him was none other than Snape, still wearing his usual black clothes.

Lockhart waved everyone to be quiet, and then shouted: "Come around, come around, can everyone see me and hear me? That's great." That's right, Professor Dumbledore allows me to open this little shop. Dueling Club, fully train you in case you need to defend yourself one day, protect yourself in the same way I have used countless times. For details on this, please see my published works. Let me introduce my assistant, Professor Snape," Lockhart said, grinning broadly. "He told me that he himself knew a thing or two about dueling, and he graciously agreed. , assist me with a small demonstration before class. I said, I don’t want you little guys to worry. After I finish demonstrating with him, I will return your Potions Master intact to you, so don’t be afraid.”

"Lockhart is asking for death," Zhang Chen said quietly to Harry and the others. After experiencing Snape's guardian magic, he had a rough estimate of his strength. However, no matter how you look at it, it is not Lockhart. This parallel import can only be dealt with.

Lockhart and Snape turned to each other and bowed. At least Lockhart bowed and did many tricks with his hands, while Snape just shook his head impatiently. Then they held their wands to their chests like arrows. "As you can see, we hold our wands in the normal dueling posture," Lockhart told the silent crowd. "On the count of three, we cast the first spell. Of course, none of us will do it. The other person's life." "I don't dare to bet." Harry whispered as he watched Snape show his teeth. "One, two, three" they raised their wands over their shoulders at the same time. Snape shouted: "Expelliarmus". Suddenly a dazzling red light flashed, and Lockhart was struck unsteadily. He flew backwards off the stage, hit the wall, then slid off and curled up on the floor.
