Chen Ping, who returned to his residence, sat on a high-back chair, with a quill floating in front of him, squeaking something on a piece of parchment paper. If he saw it, he would find that what Chen Ping wrote at this time was the Potions book he had read before belonging to the mixed-race prince, the annotations and explanations, as well as the spells developed by some authors.

Next to him, Luna was standing next to the alchemy test bench, skillfully processing the medicinal materials in different categories, putting them into the crucible, and then stirring them.

The smell of magic potions was scattered in the air. Chen Ping took a sip from time to time, nodded, or said a few words. This textbook of magic potions gave him a deeper understanding of magic potions in this world, and he also used the preparations these days to selectively teach this knowledge to his disciples.

Finally, after several hours of busyness, Luna's table was neatly arranged with about twenty bottles of potions, and her face was still a little tired and the remnants of fireworks, but her joyful look had already shown her mood and harvest.

"Very good, Luna, you have proved to yourself how outstanding you are. Just because you are at the current level of magic potion, you can successfully pass the newts exam on magic potion." Chen Ping gently patted his palms twice and expressed his encouragement.

Luna blinked and said playfully: "Is there any reward?"

Chen Ping was slightly stunned, and a rare warmth suddenly surged into his heart. Over the years, he has been wandering among the sea of ​​swords and fires all day long, how many times have he been able to enjoy such tranquility?

"Of course, my little Luna." Chen Ping stretched out his hand and stroked the girl's hair.

"From today, I will teach you the most important skill that a wizard should master."

He took out his wand and waved it in the air, and several flower-shaped English letters emerged in the air.

“alchemy”

"Alchemy?" Luna said unexpectedly.

In the world of Harry Potter, the word alchemy contains meanings that have changed from its original broad meaning to a partial discipline that tends to material transformation. Especially after the death of Nicole-Lemay, there were very few wizards who had outstanding achievements in alchemy. As the peak work of alchemy, there was only one magic stone left. After Voldemort's defeat, this magic stone was preserved in the treasure house of the Gulin Pavilion Bank.

Chen Ping smiled: "Do you know, when I came to Hogwarts and found out that Hogwarts didn't have the class of alchemy, was I surprised?"

Looking at Luna who was confused, Chen Ping said with a sarcastic tone: "In my opinion, a magic school does not have the class of alchemy, which is as strange as if there is no class of English in the school in the Celestial Empire."

Of course, Luna wouldn't understand what he was saying, so Chen Ping continued.

"For today's wizards, alchemy is just a somewhat outdated noun, but in my opinion, alchemy is the most important of all magic disciplines. If the entire magic knowledge system is compared to a building, then alchemy is the foundation and support of the building. Without alchemy, there is no magic."

"The earliest recorded alchemy in this world are Zosimus and Hermes. They lived in the third century AD. According to the history of magic, they are also the oldest wizards in the world. When they studied elements, they found that through a mysterious power, they could make certain changes in the elements. This change was originally intended to convert ordinary metal into gold, so it is called alchemy. In fact, the origin of alchemy was that those with magic power used their magic to change the elemental composition of objects, so the core of alchemy was the transformation of elements."

"Alchemy was originally a very broad word, which included inscriptions, enchantments, potions, jewelry, gems, etc. Some modern people's disciplines such as chemistry and medicine were also derived from alchemy. Therefore, proficient use of alchemy is the knowledge that an excellent wizard should have."

"Although Hogwarts does not have alchemy courses, the two courses of potions and ancient magic literature are all part of the category of alchemy. Professor McGonagall's transformation courses are also related to alchemy. You have learned some of this, so I won't introduce them specifically."

"Precisely because the knowledge of alchemy is so extensive, if you talk about it all, it will probably not be enough for a lifetime. So what I want to teach you today is the very practical content, about the production of magical items."

Anyone who is familiar with the plot of Harry Potter knows that in the whole plot, although most items have magic power, these items do not have much practical value. They are just interesting and fun, or as a decorative item. Those props with powerful magic power are quite limited and precious. Even big names like Voldemort use only a good magic wand. The materials he used to make the Horcrux are not so powerful as saying that they have

Important commemorative significance. Most of the rare items are related to black magic and curses. What can be said to be powerful magic items are, except for the Philosopher's Stone, Gryffindor's sword and hat, memory basin, light-out equipment, etc., and even the robes worn by wizards are just ordinary fabrics, not powerful protective equipment. Compared with the luxurious and practical magic equipment of the masters in the magic world, they are extremely shabby.

"I have wanted to learn how to make magical items, but my father has never allowed me to touch these things." Luna said with a dim look.

"Because of your mother?" Chen Ping asked sensitively.

"Yes, unlike you, the secrets of making various magical objects have always been in the hands of a few wizard families and are their source of income. Unless they are from their own clan, or their apprentices, they cannot learn real knowledge. If you want to learn this, you can only try it yourself. My mother died in the experiment of studying magical objects." Luna said.

Chen Ping nodded and said, "I understand, but I don't agree with this approach."

He said seriously: "The more important, precious, useful knowledge is, the more the person who owns them has the responsibility to pass them on. What they need to consider is to choose the right students instead of holding on to them, and letting this knowledge die with them in this world. In my opinion, it is simply a crime."

He stood up, held Luna in his arms, gently stroked her long hair and said, "You are my student, so I should teach you the knowledge I have mastered, and when you have the right students, you should do the same. This is not a question of whether to teach or not, but a question of choosing the right person!"

"I understand, Teacher Zhang Liang." Luna wiped her red eyes and said.

"Well, before I teach you about the making of magic items, I want to ask you a question, why do wizards need magic items?"

Luna turned her head slightly and thought for a while: "Because any wizard, whether strong or weak, has limited power, and magical items can effectively enhance the wizard's power or use powers that he does not have."

"What else?" Chen Ping continued.

Luna's eyes lit up and said, "The existence of magical items makes it possible for wizards to use multiple magic at the same time."

"Very good, is there any?" Chen Ping continued.

"What else?" Luna pondered for a moment and shook her head.

"There is another thing you didn't expect, in fact, most wizards rarely realize, that is the passivity and effectiveness of magical objects."

“Real validity?”

"Most wizards nowadays have an understanding and use of magic, including the use of magic during combat, based on their own consciousness." Chen Ping explained: "Witches usually make judgments based on their current experiences and choose to use appropriate spells. This is not wrong, but there is a premise that the wizard's senses and thoughts are not always correct. A considerable number of opponents faced by wizards have powerful abilities, which can deceive the wizard's senses and even the wizard's mind."

He said, shook his wand and a exactly-same Chen Ping appeared beside him.

Then, he shook his wand again, and both Chen Ping turned into heads and feet, and turned upside down. He shook his wand again. In Luna's eyes, Chen Ping was no longer Chen Ping, but the whole world. But her psychic vision told her that nothing had changed, and she saw only illusions.

"For example, a wizard can use illusion to deceive his opponent and make wrong judgments. Often times, such wrong judgments are even fatal."

As he said, the two Chen Pings became one in front and one behind, clamping Luna in the middle, and the wand in his hand also turned into a dagger.
