After the Potions class, Ryan returned to the common room. After that, he took advantage of this free time to continue his research while waiting for Hermione and them to return from the exam. But the wait was hours, and it wasn't until late in the afternoon that Hermione and Ron came back from outside.

"Ryan. Hermione waved at Ryan as she drilled through the portrait hole and said, "I passed the test this time." ”

"I knew it. Ryan said happily after hugging Hermione. "I already knew you could pass this test, but by the way, what about the other people who went to Hogsmeade with you?"

"It's not that good. Hermione shrugged. "At most, 1/3 of them passed this exam, because the proctors at the Ministry of Magic were much stricter than they thought. Of course I can understand this, after all, transfiguration is a very dangerous magic, and it would be grossly irresponsible to get a permit for someone who is not skilled enough, just like we give a driver's license to someone who can't drive-"

"Oh, Hermione, I think those people are a little too harsh. Ron sat next to him and looked a little listless, saying that he had been in this state since he got in. "I was so unlucky because of something big – the examiner just saw that I had lost half an eyebrow, just half an eyebrow...... By the way, how about Slughorn's side?"

"Very good, at least there are no problems with the first step of our plan. Professor Slughorn has now invited me to his office tonight to join him. Harry said, then comforting a frustrated Ron by saying, "You're just out of luck this time, I think you'll pass the next exam - and you can take it with me and Ryan." ”

"I think so. Ron was much better after hearing the comfort, but he was still a little depressed, "I lost half an eyebrow in this exam!

"You can't say that. Hermione's expression became a little serious. "Once there is a problem in phantom shifting, it is completely uncontrollable to lose anything, and if you can lose half of your eyebrows, you may also lose half of your thighs. So those people don't allow you to pass for your own good—"

"Enough. Ron looked at Hermione helplessly, "Please, can you stop talking about it, it's already made me very uncomfortable to smash the exam today." ”

"Well, I'm not going to talk about it. Hermione didn't say anything about the exam again, but walked downstairs to the auditorium with everyone for dinner, and listened to the students' comments about today's exam.

Most of the people who took today's exam were scolding the phantom apparition examiner during their meals, and the few who passed were expressing their sense of happiness for the rest of their lives. Listening to what they said, Ryan almost thought that they were not facing the illusion transformation exam, but had just run past a large group of fire dragons.

After returning to the common room, Harry began to prepare his plans for the evening. He sat on the couch in the common room, took out the small bottle, looked at it, and said. "I don't think it's necessary to finish this thing, I shouldn't need 12 hours of luck tonight. It will take four or five hours to reach the final conclusion. I only need to take a sip, and two or three hours should be enough. ”

Because they had only seen Slughorn enter the Great Hall when they had gone upstairs before, and knew that he liked to enjoy himself, and he was slow to eat. So Harry decided to recharge his batteries in the common room now and wait for Slughorn to return to his office.

As the sun cast its last rays of the day on Hogwarts Castle, Harry figured it was coming up. So he and Ryan went to the same place as they went to an empty classroom across the hallway from Slughorn's office, took a sip of the bottle, and then took a sip of the bottle.

"How does it feel?" Ryan asked with some curiosity, he Hermione had analyzed the potion more thoroughly before, but he had never drunk such a thing. So he was more concerned about how he felt after using this potion.

"It's wonderful, it's wonderful. I thought it would be a good idea to go straight to the Slughorn office in two minutes. Harry smiled and stood up, full of confidence. "That's right, Ryan. Can you lend me one of your top defensive bracelets? I feel like having this thing will be beneficial for this operation, don't worry, I'm just borrowing it. ”

"How did you know I had a new product?" Ryan asked with a smile, and then took out a filigree bracelet made of Mithril silk and gold wire from the space bag, with a dozen colorful gems inlaid on it. If you take a magnifying glass and look closely, you can see that there are a lot of translucent runes on these gems and gold wires. It's like the stars in the night.

"It's just beautiful. Harry and Ron exclaimed at the same time. It's no wonder they were so surprised, this bracelet designed by the elves in "The Lord of the Rings" is indeed beautiful, and it attracted everyone's attention as soon as it appeared.

"This is the most powerful alchemy defense item I've ever made. Ryan said to Harry, "It provides enough protection against all kinds of physical and magical attacks, and I can even proudly say that this bracelet can help you block almost all the remaining evil spells, except for the Death Curse." ”

"Wow-" Ron exclaimed in surprise, the Weasleys had always had a knack for making magic props, from Mr. Weasley's flying cars to the twins' creative creation of prank props, it was clear that the Weasleys' family knowledge was all about the making of magic props. So being born into that kind of family, Ron also knows something about this kind of thing, which is why he is so surprised.

"This must be complicated, right? Otherwise, we wouldn't have seen this bracelet before. Harry took the bracelet and looked at it carefully, even someone like him who didn't have much research on magic items could feel the power contained in the bracelet in his hand.

"Yes. Ryan nodded. "This is a new product that I have recently developed after in-depth research on various new threats, and it can provide users with unprecedented protection. However, as a prototype, the cost is also so high that it has never been done before. ”

"How much does one of these bracelets cost?" Ron asked weakly.

"The cost is 1,750 Galleons, and that's not counting the manual costs. Ryan shrugged, Ron seemed to be intimidated by the price, he couldn't say a word for a long time with his mouth wide open.

"No wonder you didn't give this to the members of the Order of the Phoenix, it's too expensive. Harry said as he put the bracelet in the pocket of his robe with a serious expression. "I swear I'll give this bracelet back to you in perfect condition. ”

"It's okay, if necessary, this can be the price of your information. Some information is worth far more than money can measure. Ryan, as the maker of the item, didn't take it very seriously, and instead told Harry not to pay too much attention to the price of the item, and to use it when he needed it.

"Thank you so much, but I don't think I can get to this point, and I'll be able to easily get that memory in my hands tonight. Harry stood up and said with a confident expression. "Okay, I think it's time for me to get over now. Wait for the news of my success!"
