Dumbledore's Lead (Thanks to Southeast Savage for the power-up of love! Thank you!)

Back in the twilight of Hogwarts, Su Yu first escorted Ginny back to the common room, then brushed the fallen leaves from his robes and walked straight to the Professor of Defense Against the Dark Arts's office without pausing.

He didn't go to the Headmaster's Office, and even deliberately avoided the corridor where Dumbledore might appear. He didn't know why, but he thought it was best to avoid that old glass man, as he had a feeling that Dumbledore trick him.

The wooden door to the cubicle was gently pushed open, and Isolde Rozier was sitting at the table organizing course materials for the advanced Defense Against the Dark Arts. Her lips were painted with the most vibrant lipstick, and her long, dark hair flowed smoothly over her shoulders. Her eyes and brows still held that cold and composed air, and her ten-centimeter high heels were faintly visible through the gap under the table. She looked delicious.

Upon seeing Su Yu enter, she immediately put down her quill pen, stood up, and bowed respectfully and appropriately. As Su Yu's secretary, she was always clear about her responsibilities and was just waiting for Su Yu to speak.

Su Yu sat down in the leather chair she had just been sitting in, and casually pulled Isolde into his arms, gently burying his head in the soft fabric, taking a deep breath, feeling incredibly comfortable.

"I just returned from Sen- Carl and found some clues about the Goblin' unusual activities, as well as traces of their secret collusion with Hell." Su Yu slowly revealed the key information he had compiled to the woman in front of him.

Isolde listened attentively, her fingertips unconsciously tapping lightly on the table, memorizing every detail. However, her boss's hands slightly affected her concentration.

After Su Yu finished speaking, Isolde nodded slightly, her voice cool and calm. "I understand what you mean, boss."

"Report everything to Grindelwald verbatim first," Su Yu instructed, raising his eyes. "Leave the rest to him to negotiate with Dumbledore."

Isolde simply replied respectfully, "Yes, boss, I'll take care of it immediately." She never said anything unnecessary, only executed orders precisely.

"Alright, now that we've covered the important matters, let's get down to business." Su Yu raised his hand and turned Isolde around.

"Now, boss? Isn't it a bit inappropriate to be here?" Isolde knew Su Yu all too well; she knew he liked this kind of thing, which was why she had been pretending to be the victim.

An hour later, Isolde straightened her torn stockings, watching Su Yu's departing figure. It took her a while to recover before she got up and organized all the information Su Yu had given her. After confirming it was correct, she changed her clothes and turned to walk towards the hidden passage leading to Grindelwald's residence. Her steps were calm and composed, showing no sign of what she had just experienced. She just felt a little tired. Practicing yoga on her desk—only he could have come up with that idea. She wondered how those two Slytherin girls managed Tenten. At this rate, she would need at least ten hours of sleep a day. She was so tired, Isolde thought as she walked.

The following afternoon, in the Slytherin Common Room, the waters of the Black Lake flowed slowly outside the window, and green spots of light moved across the ceiling. Several younger students huddled in a corner playing chess, with occasional bursts of laughter and playful banter.

Su Yu leaned back on the sofa, while Kurama leisurely ate the afternoon dessert that Daphne had prepared for her with Egg Beater. Her tail wagged unconsciously, proving that she was in a very good mood.

Su Yu was flipping through a Potions notebook he had borrowed from Daphne. With exams approaching, not only was he studying hard, but Daphne and the others had also been going to the library to Tenten.

The door to the common room was pushed open. Su Yu didn't look up. He had deliberately stayed in the common room to wait for Isolde. Today she was wearing a dark gray trench coat with the collar turned up and her hair tied back. However, she had changed her stockings to mesh ones. She paused at the door, glanced around the common room, and then walked straight toward Su Yu.

Kurama's ears twitched, and he spat out a mouthful of Su Yu.

Isolde stopped beside Su Yu, bowed slightly, revealing a patch of snow-white skin, and said, "Boss, Professor Graves has already spoken with Dumbledore about what you found out earlier."

Su Yu inserted the bookmark into the book and closed it.

"Have you talked to him?" Su Yu asked. "What did Dumbledore say?"

Isolde didn't respond. She pulled a folded piece of parchment from her trench coat pocket, held it in her hand without unfolding it. "Dumbledore said there's a lead at the Three Broomsticks tavern in Hogsmeade. Ranrok's brother frequents there, and Rosmerta, the tavern's proprietress, knows him well."

"Ranrok's younger brother?" Su Yu frowned.

"Yes, Ranrok," Isolde said. "Ancient Magic scholar who disappeared forty years ago. His brother Lodgok, now lives in Hogsmeade and frequents the Three Broomsticks."

"Does Professor Graves mean for me to go through Madam Rosmerta to see Lodgok?" Su Yu asked.

Isolde handed him the parchment. "Should I find some time to visit the Three Broomsticks and, through the landlady's introduction, go see Ranrok's brother and see if he has any news?"

Su Yu took the parchment and unfolded it. On it were several lines of neat handwriting. The paper stated that Ranrok's birth and death dates were unknown, the year he went missing, Lodgok's current residence, and there was a line of smaller print. "Madam Rosmerta knows the facts and can be trusted."

Su Yu glanced at the parchment, folded it, and put it directly into his pocket. "You don't need to go. I'll investigate this matter. Ginny also wants to go on an adventure, so I'll grant her wish and take her along."

Isolde nodded, her trench coat swaying to reveal her thighs. She leaned close to Su Yu's ear, blowing warm breath, and whispered, "Boss, it seems like none of the boss's wives are here today. You... you won't do anything strange to me, will you? And, I'm wearing red nail polish today..."

"You, come back to the dorm with me, I have something to tell you!" Su Yu said with a righteous expression, as if he really had something important to tell him. It was mainly because Isolde was too good at it, she could change things up Tenten!

Kurama looked up from the cheesecake, its ears twitching, and knew that Su Yu was up to no good!

As night slowly enveloped Hogwarts Castle, and the sky outside the window grew completely dark, the castle's hallway lights gradually came on, before a dark figure emerged, limping slightly, from the Slytherin common room.

Not long after, Ka-jie, Fa-jie, and Daphne walked in together. After finishing their studies in the library, they brought food they had prepared for Su Yu to his dormitory.

The group looked at Su Yu lying on the bed, then smelled the air, secretly lamenting that the philandering cat had returned. The girls then casually found seats, ignoring Su Yu's behavior, and relaxed, chatting about trivial matters at the academy in a relaxed and carefree tone.

After chatting for a while, Su Yu, who was lying on Daphne's lap, took the opportunity to tell her about what had happened that day and his plans for tomorrow.

"Dumbledore said the Three Broomsticks tavern might have some clues. I'm going to see Rosmerta, the landlady of the tavern, tomorrow and meet Ranrok's brother to see if I can dig out any more useful information."
