The young Oriental professor walked up the slope and warmly greeted Dumbledore: "headmaster Dumbledore, I'm ang Chen, the new professor of black magic from demstrom..."

Dumbledore nodded and replied, "welcome, friends of demstrom. Hogwarts entertains every friend from afar... May the little Wizards of demstrom reap friendship here."

"And knowledge..." Chen ang added with a smile.

Dumbledore smiled, "yes, and knowledge!"

"Chen..." Dumbledore looked back and asked in a low voice, "can I call you that? I remember your Oriental names are often behind, so I should call you... Chen Ang?" Chen ang nodded and Dumbledore smiled: "I know this secret from the pronunciation of your name. One of my students is a third grade Witch of Ravenclaw... She should be like you. You are all Chinese."

Chen ang nodded slightly, but he was thinking. Did the old bee really stare at him?

"Is Professor Igor all right?" Dumbledore asked, "he asked someone to contact me. He didn't show up for the exchange between our two schools. This time I thought he would come in person..."

"Headmaster Igor is inconvenient." Chen ang replied, "you should know that it is rumored recently that Voldemort is back. The death eaters are moving around, and Professor Igor feels very uneasy and reduces his walking. The Death Eaters hate him to the bone, but London is the base camp of Death Eaters... So headmaster Dumbledore, you must not see him step into London!"

Dumbledore stopped and looked at Chen Ang's calm expression. His eyes were deep. He thought like an old man for a while, as if he were remembering. For a long time, he sighed: "Igor... Professor Igor had a bad experience in the past, but he made the right choice later. He should have come here!"

Chen ang said lightly, "people are always responsible for what they have done... No one can escape this."

Dumbledore invited demstrom's exchange students to live in Hogwarts' dormitory, but Chen ang politely refused. He turned their boat into a villa and took demstrom's students to live in. Harry heard Professor McGonagall whisper to Dumbledore, "that's a very difficult deformation..."

She seemed to notice Harry listening and added: "the larger the deformed object, the more magic it consumes. Few people can turn a house in one breath... Very few!"

Dumbledore smiled in a low voice: "Professor Mileva is one of them..."

"I can do it, but the difficulty of the spell has nothing to do with the magic consumed." Professor McGonagall was silent for a long time, and then added: "without the help of magic words and potions, I can't last long."

Harry couldn't hear the back, so Ron pulled him over and heard him whisper, "I see Victor Krum."

"Who?" Harry asked.

"Victor Krum, the new seeker of the Bulgarian National Quidditch team... People say he is the most talented seeker and future star in the history of the Bulgarian team. Although he is not so famous now - he is widely praised. Maybe I can ask him for an autograph."

Ron sighed: "their red robes are much more conspicuous than our black robes..."

When they went down to breakfast the next day, they found that the hall had been decorated overnight. A huge silk long piece hung down from the wall. On the left was the representative color of Hogwarts, including red golden lion, green silver snake, blue Golden Eagle and yellow black badger, all around Hogwarts, forming the destruction of Hogwarts.

On the right is the double headed eagle emblem of the Byzantine Empire representing Slav, northern Europe and even Germany. Its wings are spread. Below is the goat skull representing black magic, which together form the emblem representing demstrom.

Harry and Ron saw the exchange students from demstrom on Gryffindor's table. They had taken off their heavy leather clothes and showed that they were wearing blood red robes. When they saw Gryffindor's students, they would greet them warmly, but somehow Harry always couldn't forget the pale and dead faces he saw on the ship.

Chen ang and Dumbledore sat at the staff table. He had met most of Hogwarts's professors yesterday, but because it was night, they just met in a hurry, Chen ang had to take the students back. This time, sitting on the staff table with most of Hogwarts's professors, he could have a deeper contact.

The LORD God's task was completed as early as last night when he met Dumbledore.

It seems that the LORD God has no specific requirements on how to "enter" Hogwarts. Even if Chen ang is only a professor from other schools who came to communicate, he has reached the lowest bottom line to complete this task.

Dumbledore was sitting on his left hand, and Snape was the old bat on his right. Although Chen ang was not very particular, was it really appropriate for Dumbledore, the old bee, to arrange a bat that likes to spray poison and doesn't repair space next to the guests? Hermione found the problem, and she bowed her head and whispered to Harry: "The professor of demstrom seems uncomfortable sitting next to Professor Snape."

Ron gloated, "no one wants to sit next to that greasy old bat."

Dumbledore seems to have noticed that each of the exchange students in demstrom has a "walking stick". It is a "walking stick" as tall as demstrom's strong wizard chest like a bear and as thick as a duck egg - in fact, it is a stick with the color of a log... This thing is not light. In fact, it is made of iron birch.

That kind of wood used to replace steel bearing balls in the Muggle world is a good thing produced on the cold plateau of Siberia.

Dumbledore even noticed that the Wizards of demstrom had a thick cocoon at the mouth of the tiger. Even the witches, under their youthful and beautiful appearance, were thick thighs and arms full of muscle pimples, especially their leader Victor Krum. His walking posture with a stick made Muggles who knew Oriental martial arts admire: "This must be practicing stick skills to the bone!"

Dumbledore has no martial arts attainments, but he is not a fool. Of course, he can see the plagiarism of these Slavic barbarians.

He asked in a low voice, "Professor Chen, I don't know what demstrom's students are holding in their hands?"

Chen ang smiled: "That's their new magic wand... Demstrom is launching a reform campaign. We have noticed that the dependence of wizards on magic wands may be abnormal. Now most wizards can hardly use magic without the help of magic wands. You know, magic wands are only an auxiliary tool... We realize that this tool may be suppressing the potential of wizard development Force. "

"Especially when young wizards grow up, the help of magic wands may cause dependence, resulting in the decline of wizards' control and stability of magic. This makes us worried. It is worth noting that only wizards in Europe use magic wands. The uagadou Magic School in Africa does not use magic wands, but uses gestures to stably release the magic of magic spells."

"This may be directly related to the amazing deformation talent of the students in wagadu magic school. According to our tracking research, wagadu students play a role in spells requiring control and stability. The reason why this problem has not been found is that they do not use magic wands to cast spells. Therefore, in those spells requiring control, we compare our performance with those using magic wands Flat. "

"But the magic that cannot be performed with the aid of magic wands, such as self deformation - Animagus, can be clearly displayed. It can be seen from the performance at the recent international Animagus conference. The 14-year-old wizards and witches scared the adult wizards in Europe!"

"This deserves our attention." Dumbledore's face became serious, and he whispered, "this is a valuable discovery... But the relationship between wizards and wands is very complex. Each wand and wizards are closely related. First, they attract each other, and then adapt to each other. In this process, wands learn from wizards, and wizards also learn from wands."

"Yes." Chen ang nodded, "without the guidance of the magic wand, the magic riot will not be relieved when the wizard grows up. We have noticed the important role of the communication between the magic wand and the wizard in the growth of the wizard's magic."

"So while we keep the students' traditional wands, we also need to find alternatives."

Dumbledore's eyes were bright and he said curiously, "have you found it?"

Chen ang nodded: "I have found the magic materials that are also very good at communicating with wizards - gemstones, colorful crystals and different gemstones. They also have the same complex 'personality' as the wand, which is very suitable for attracting each other with wizards. We use the most stubborn wood - iron birch as the material of the wand. Its characteristics are well known for its stubbornness and stability, which can maintain the wand Under the effect of relieving magic, exercise the magic control of casting magic spells. "

"Then the head of the wand is inlaid with gemstones to replace the ability of the wand and the wizard to learn and communicate with each other."

"Finally, hand gestures are used to assist in magic casting. Those complex magic spells that need wand assistance will be combined by hand gestures and wands. Therefore, we have specially developed a set of one hand gestures to cooperate with this wand."

"We are even developing a set of rituals to encourage wizards to concentrate and communicate with magic wands and gemstones, so as to be more active in communicating with magic wands. It includes a complete set of rituals to maintain magic wands (gemstones), burn spices, bathe, change clothes, calm spirit and meditate. Preliminary experiments show that the results are good."
