"This is a simple illusion. As you can see, it is such an illusion. It is effective for those wizards who have no experience. However, your eyes can be deceived, and the magic props you carry will not be deceived. As long as you remember to use them, they will still play their due role. For example, in this case, when you cannot judge which opponent is real, if you have a defensive magic item on your body, you can choose to directly activate the defensive spell on the equipment to buy you some time."

"I understand a little, but I don't understand very much." Luna said.

"Well, let's do it. Our class starts with making a small toy. I ask it to locate the teleportation ring." Chen Ping said, taking out two small boxes from his bag and giving Luna a message.

"This is a set of jewelry tools, which contain pliers, carving knives, files and other tools. I attached sharp magic to them, which can cut most metals with less hardness."

Then he took out two small pieces of brass, a small roll of silver filaments, and a few small pieces of crystal stones that were shining with a pale white light.

"I'll give a demonstration, first of all, the custody."

He picked up a small piece of brass and a knife and quickly cut it along the edge. After more than ten seconds, the brass turned into an inconspicuous ring, and on one side there was a cross-shaped slot. He cut a small piece about two centimeters long from the roll of filament, twisted around the slot into a small ring holder.

"This kind of ring is mainly practical, brass is enough, but the ring support needs to have good magic conductivity. I used mitril silk as a conductor of magic."

He took out a thin short staff from the tool, and the tip-sized end of the staff spewed out a faint blue flame, fusing the two together.

"In the end, it is the main body of the ring, the magic crystal."

He picked up a piece of crystal, carefully embedded it into the ring holder, and fixed it: "That's all. Most magic rings are similar to this thing, the ring body, conductor, and magic core. As long as these three are all ready, they are a qualified magic item."

"In this ring, the most important thing is the crystal on it, or rather the magic array sealed in the crystal. This involves the application of ancient magic texts and magic arrays. You need to first draw the magic array on the scroll and then seal it into the crystal carrier."

"The production of magic scrolls requires good quality crust paper. Most of them use parchment paper, and very few advanced ones use magic skins, or even dragon skins. The ones used to draw magic texts require specific hair-making pens, as well as ink made from blood or magic plant liquids. Then seal the magic array into the ring through specific spells. These are things you need to learn, but today, let's make a few such rings first."

"What's the use of this ring?" Luna asked with the simple ring made by Chen Ping.

"The function of this ring is very similar to Pochi. It is a disengagement prop. Unlike Pochi, it uses the shape-shifting spell, not Pochi's flying spell. In addition, it is an excitation type, not a trigger type. When you encounter danger, as long as the spell inside is activated, the ring will teleport you to me. According to the capacity of this crystal, it can be used within 500 meters, and each crystal can only be used once, but as long as it is used well, it is still a very useful tool."

Chen Ping told Luna how to inspire the spell and said: "There is a powerful teleportation restriction magic in the castle, so this ring can only be used outside the castle."

"I understand that compared with the shape-shifting magic, this ring has a more stable effect, especially in dangerous situations, which is more reliable than hastily using the shape-shifting magic."

"Yes, that's what it means." Chen Ping took out a few more crystals and placed them on the table.

"Look at these crystals and tell me, what's the difference?"

Luna looked at the crystals curiously. The crystals were not much different in appearance. The difference was that the structures were some empty, and they looked no different from ordinary crystals. There was only an extra magic array constructed from three runes. Some contained magic power in the middle, emitting a faint white light. Like the previous ones, one of them was also empty. Not only that, the runes inside were also destroyed.

"I think these should be crystals used on the ring. These are not charged. These are fully charged. The last one is broken. "Luna said in uncertainty.

“Verified.”

"You should know that most wizards will choose spell scrolls made of parchment paper as tools for storing magic, but as a psychic, you need to gradually get used to using crystals to replace scrolls. This is not only because the form of crystal is more stable than parchment paper, but also because the flexibility of crystals in use is far greater than that of parchment paper scrolls, and is embedded in magic jewelry. It is just one of them, and it is more used in the layout of magic circles. The effect of the magic circles on the stimulation array is much better than that of the parchment scrolls. Can you imagine opening the magic scrolls one by one in battle and chanting the magic spells on it? If you use magic crystals, just input magic power directly according to arcane powder or blood and other media, the magic crystals on each node can be automatically activated."

After explaining the advantages and production methods of magic crystals, Chen Ping began to instruct Luna to make a teleportation ring for each of Harry and others. A few hours later, the enlightenment lesson on the production of magic items came to an end.

"Okay, let's get here. Let's go and have a rest. Tomorrow will be very hard." Chen Ping ordered.

Harry and others didn't sleep well this day. First of all, it took them a lot of effort to prepare the potion task assigned by Chen Ping. These potions are all intermediate potions in standard potions, and it is quite difficult to mix them. When Hermione finally completed two of them, she saw Harry and Ron still mixing them up there.

"What's wrong, Harry, didn't that mixed-blood prince help you this time?"

Although Chen Ping had checked the old textbook, Hermione had been opposed to the additional knowledge and skills he used in the textbook, especially when Harry became Slughorn's darling with these guidance.

"Well, we haven't specially prepared these potions, and Snape hasn't taught us these." Ron argued.

"Hmph, I knew that most of the mixed-race prince wrote in the textbooks only related to the contents of the textbooks. Once the things to be matched are not in the textbooks, it will not work much." Hermione said proudly, "You should take a look at this first, "Advanced Magical Potions", "Conventional Battle and Guardian Potions", and "Magic Potions Used in Emergency Situation".

She threw a book that could be used as a weapon on the table, and every time she put a book on it, the table would shake.

So the next day, when three poor guys appeared in front of the wooden house in Haigree with dark circles, they were still whispering something.

"Oh my God, we actually overslept. Not only did we miss Professor Flitvie's spell class, but we also missed the selection of personnel for the Quidditch competition." Ron muttered.

"Quidditch is easy to handle. Hermione has informed everyone on my behalf to postpone the selection until tomorrow, but Mr. Flitvie's class." Harry scratched his matted hair in his head, "Well, in addition to Snape's confinement this week, we must also go to Professor Flitvie's place to make up lessons."

"Just to take this damn magical creature protection class, you know I want to be the goalkeeper of Quidditch," Ron said.

"Ron, you are not allowed to say that Hegree." Hermione said angrily. "And I am looking forward to what kind of surprise Zhang Liang will bring to us."

"Hey, what is that?" Harry shouted at the area ahead.

In the direction Harry pointed, the three of them were surprised to see that there was a hexagonal yard of hundreds of meters in radius next to the Haegre's hut. The outer edge of the entire yard was a curtain made of vines and curtains, blocking the three of them. The curtains on all four sides were red, blue, yellow and green, corresponding to the four colleges, while the other two sides were white with doors and black covering the same thing as square cages.

"I seem to have a bad premonition." Ron said.

"I seem to have seen this pattern somewhere." Harry thought for a while.

"Is that?" Hermione said with a strange expression: "Circus?"
