The reason why Ryan kept the bottle full of wolf poison potion in the Room of Requirement was because even though the runes were used to solidify the Traceless Stretching Charm on that bottle, Ryan didn't compress too much space to avoid multiple runes on the bottle from conflicting. So the final product is about the same size as a thermos.

In this way, this big guy is not suitable for being around. And as an alchemical product used in this world. Whether it is taken to other worlds or stored in space equipment, the final test result will be affected. So Ryan took care of safety and placed it in the place where the Ravenclaw crown was hidden in front of the Room of Requirement. And now Ryan: They're going to the Room of Requirement to check how well that bottle works.

At this time, because it was late, the corridor was empty and there was no one else. Only Ryan and Hermione walked quietly in the hallway, their shadows dragged away by the dim light. However, when they reached the stairs on the seventh floor, they suddenly found two Slytherin students hiding in the shadows. Fortunately, there weren't many torches in the hallway, and the dimly lit hallway kept the two Slytherin students from spotting Ryan and Hermione, who had flashed around the corner.

"What are those Slytherins doing here?" asked Hermione, poking her head out of the corner, glancing back. Due to the proximity of the Gryffindor Tower, Slytherins who normally live in basements do not come here. Just like Gryffindor doesn't tend to go to the basement at any time other than Potions class. So at this time, it seemed strange that two Slytherin students were sneaking around here.

"Have you seen Harry or Ginny after dinner today?" asked Ryan as if he had thought of something.

"Nope. Hermione thought for a moment and shook her head. "Normally Ginny would be in the library, but today she wasn't. ”

"I seem to know something. Ryan suddenly remembered that Harry had been wiped out before Easter because of the presence of traitors, and it seemed likely that it would be today. Thinking of this, he quickly told Hermione beside him about this as his own conjecture.

"It should be. Hermione suddenly remembered that she had found that information when she had set up a book club. "Damn, since the Mysteries organized the Walples Knights at the school and used them to try to conquer the entire wizarding world. Now all wizards have been in a very sensitive state to this illegal organization. In particular, Ginny told Harry that they had written a list of Dumbledore's Army, so that if Harry was caught, there was a good chance that Headmaster Dumbledore would be implicated, so we had to figure out something to do. ”

"Think about it. Ryan touched his chin and motioned for Hermione to lean his ear over before muttering a few words. Hermione nodded solemnly, then pulled out the wand she had captured from the Death Eaters, and then took a small test tube from Ryan.

The tube looks like it's empty, but if you look closely, you'll see a red hair inside.

"Let's go our separate ways, I'll go over and solve the problems in the Responsive Room, and you can help me clean up the perimeter on the perimeter. Ryan finally admonished. "By the way, let's be lighter. They're our classmates. ”

Hermione nodded, and the two of them used the Manifestation Charm to hide themselves at the same time.

While Ryan and Hermione were beginning to carry out their plans, Harry was hiding in the Room of Requirement to instruct the members of the Patronus spell to practice, and everyone was practicing so hard that many of them had already mastered the method of summoning the physical Patronus. Others were able to summon a dense and thin silver mist.

Just as Harry was prompting a few of his classmates to reminisce about happy events, the door to the Room of Requirement opened and closed. Harry turned his head to see who had entered, but there didn't seem to be anyone at the door. After a while, he noticed that several people near the door were silent.

Later, he was surprised to find Dobby standing beside him and pulling his pant leg. At the same time, he shuddered and screamed, "Harry Potter, sir, Dobby has come to report to you, but the house-elf has been warned and can't say-" At this point, Dobby began to bang against the wall, and several of the girls screamed.

Harry grabbed Dobby to prevent it from continuing to harm itself, and Dobby relented a little and said, "Harry Potter!

Harry understood for a moment, and then asked in horror, "Umbridge? What's wrong with her? Dobby- she found out about this- she found out about us- found out.?"

Looking at the elf's sad face, Harry swallowed and asked one last question. "She's coming?" Dobby let out a cry and began pounding the floor with his two bare feet. "Yes, Harry Potter, yes!"

Harry showed his decisiveness in a moment of crisis, shouting for everyone to evacuate, and then arranging for Dobby to take refuge in the kitchen.

"Harry is a good man, and it seems that he did not become the heir of Old Deng only by virtue of the prophecy of Voldemort's opponent. By this time, Ryan had already stealthily touched the door of the Room of Requirement, and happened to see the scene where Harry had arranged for Dobby to take refuge through the open door.

Now there was a mess outside, with members fleeing in a panic and Umbridge chasing after some of the Slytherin students. Taking advantage of the chaos, Ryan dodged into the Room of Need.

The Room of Requirement was now suitable for practicing Defence Against the Dark Arts, and Ryan could see at a glance the list nailed to the wall facing the door, with Dumbledore's Army written in floral script on the top.

"Harry, they're not suited to this kind of stealth activity. Ryan shook his head, then put the list away. When he was out of the house, he almost bumped into Parkinson's who rushed in. Luckily, Ryan grabbed the lintel with his hook and jumped over Parkinson's head.

"Let's hope it will be different this time. Ryan thought about retreating to meet Hermione in the agreed empty classroom outside the library, only to open the door and bump into Hermione, who had adjusted her clothes after removing the Faceless's transformation magic.

"It's you, Ryan. Hermione raised her wand vigilantly, and lowered it only after confirming that it was Ryan. "You're just here, help me look at the back of my clothes where I can't see, I feel like the threads on my clothes are open. ”

Ryan stepped forward as he was told, only to see that there were indeed a few lines behind Hermione's clothes. He raised his wand and repaired his clothes as he asked. "What's going on? Can those Slytherins still hurt you?"

"It had nothing to do with the Slytherin group, I thought it might be the same cute little girl you did last time, so I thought I'd wait until I was done with my clothes to fit my clothes. I didn't expect it to be an adult woman this time. Speaking of this, she subconsciously pulled the clothes on her chest.

"This is a priest under one of Rose Crystal's sisters. Ryan explained that since the last embarrassing outfit, Ryan had gathered enough hair from several worlds to avoid doing something like this again. As a result, when Hermione was preparing just now, Ryan directly pulled one directly from the row of test tubes containing women's hair in the space bag, but he didn't expect that this time the template was completely different from the last time.

"It's better to make it clear to me next time, so that I can be prepared. Hermione said after Ryan adjusted his clothes, "I knocked out the Slytherins who were far away from Umbridge, and I thought Harry and his group would be able to escape a lot.

Ryan nodded. "I took Harry's list as well, but it's good that Ginny told you about it before. Seriously, in this case, they didn't even think to destroy the list in the first place, which is really bad. ”

After packing up, the two returned to the common room. All that's left is to pray for Harry.
