Seeing that Harry had brought back so many people, all the students in the Room of Requirement stood up. When they saw that it was Bai Lin who had taken off his hood, some of the students excitedly screamed on the spot.

"Look! It's Professor White!" A student who recognized Bai Lin exclaimed excitedly to the new students beside him. The new students also opened their eyes wide with curiosity, some even taking out their treasured wizard cards to "verify" with Bai Lin.

"Haha, my popularity is still going strong!" Bai Lin said with a hint of smugness.

The Weasley brothers were the first to greet Bai Lin, embracing him one by one. "I knew you'd be back!" Fred said earnestly.

"You were saying yesterday that the professor had forgotten about us..." George exposed him without hesitation.

"Everyone trusts you!" Harry's expression remained serious. He seemed much more mature than he'd seen in over six months. He continued, "Are you back at Hogwarts on a mission?"

It must be said that Harry, who will become the Auror Office Director in the future, has the keenness of a detective, or perhaps he has a deeper understanding of Bai Lin and is more rational in dealing with him, so his words hit the nail on the head.

"Yes, I'm sorry. I didn't know Umbridge had been wreaking havoc at Hogwarts for months... The news was very tightly controlled..." Bai Lin was quite frank. He paused and said, "I do have a mission, but I will not stand idly by while Hogwarts is in trouble. In fact, our goals are largely the same. My mission is to capture Umbridge... But before doing all that... I need to eliminate the danger among you..."

Bai Lin suddenly let out a low shout for no apparent reason. Yan Nishuang, who was standing to the side, had already stretched out her hand and summoned a jade pen. Instantly, a barrier made of talismans was set up in the Request-Free Room, enveloping most of the students, as if it were a fence.

This action clearly startled everyone, but Bai Lin pointed behind Ron, and everyone quickly made way, only to find that Bai Lin was pointing to Cho Chang, who was standing next to Cedric.

Qiu Zhang was clearly pleasantly surprised to see Bai Lin return. However, she had already agreed to date Cedric, and even if she had some girlish feelings of admiration for Bai Lin before, they had faded a lot by now. But being pointed at by Bai Lin still made her a little flustered.

Cedric instinctively wanted to stand in front of Qiu Zhang, but hesitated slightly because of his trust in Bai Lin.

"It's not you two, get out of my way!" Bai Lin waved his hand, and an invisible force swept Cedric and his wife aside like a large fan. Only then did everyone see that there was another girl standing behind Qiu Zhang—Mariette.

In the original story, Marietta revealed Dumbledore's Army to Umbridge. Due to Hermione's magic on the autograph book, a "snitch" pattern made of pustules appeared on her face. When Harry mocked her, Cho defended her and accused Hermione, which caused a rift in the relationship between Cho Chang and Harry.

However, Mariette's expression was somewhat unnatural at this moment, but she did not show the same panic as Cho Chang.

Bai Lin's orderly energy had already spread throughout the room without anyone's knowledge, gathering around Marieette. He took out a "brick phone"-like device from his magical pack and handed it to Harry, saying, "You should have heard of this thing. She's probably already infected..."

Harry's face flushed red and then paled. He clearly understood Bai Lin's meaning: Mariette had already been infected with the "Yellow Seal" and had become Umbridge and Hastur's spy. Everything that happened to their group here was actually under Umbridge's watchful eye. Yan Nishuang's talisman barrier served two purposes: preventing Mariette from transforming and escaping, and also cutting off any spiritual power from transmitting the message.

Before Harry could even bring the Yellow Seal Detector to Mariette, she had already made her move. Dozens of thin, yellow tentacles emerged from her eyes, nostrils, ears, and hair. She roared like a wild beast and pounced on Harry, seemingly trying to take him hostage.

But Harry is no ordinary young wizard now. He has experienced the battle with Voldemort, witnessed the power of Whitescale and Dumbledore's retirement. In the past six months, he has spent almost all his time thinking about becoming stronger. He has even given up on Cho Chang, whom he loves the most. As the saying goes, if you have no woman in your heart, magic will naturally come. He quickly drew his wand and, without casting a spell, created an invisible spatial barrier in front of him. Mariette's tentacles were blocked less than a meter in front of Harry, as if they had hit a thick glass.

The octopus-headed monster that Mariette had transformed into terrified the students. Most of them had never seen the bizarre appearance of these yellow-striped parasites before, and they screamed and ran away in both directions. But Harry remained calm in the face of danger. He waved his wand again, and two large water jugs suddenly appeared next to Mariette. This was a special effect of the Room of Requirement. Harry had obviously mastered the skill of making wishes at will in the room.

Water gushed from the kettle, instantly enveloping Marieette before quickly freezing into ice, turning her entire body into an ice sculpture.

"Wow! You've improved quite a bit!" Bai Lin was about to make a move, but he didn't expect Harry to have dealt with it so easily, which made him look at him with new respect.

"I've always remembered what you taught me: to be creative in battle!" Harry said earnestly.

Bai Lin nodded in satisfaction, signaling the others not to panic. Yan Nishuang waved her jade pen, expanding the barrier to cover the entire room. This barrier lost its physical barrier properties, but it could still prevent the penetration of mental power, preventing Mariette from having any other unknown peculiar skills.

"Please, save her!" Qiu Zhang rushed to Bai Lin, her face already wet with tears. Bai Lin knew that Mariette was her best friend, and today's events clearly meant that her friend's life was in danger. How could Qiu Zhang not be heartbroken?

"I'm sorry... I can only try to save her soul..." Bai Lin's eyes were full of pity, but he was also helpless. Under the effect of his power of order, Mariette's tentacles were cut off one by one. Then, Sifgar emerged from the space in front of Bai Lin. With a golden light, the ice had melted completely, and Mariette's body fell to the floor. She was covered in blood, but she had finally returned to human form.

"I'm so sorry..." Bai Lin said to the students again, "Although I can't save Marieette's life, I promise you all that I will make the culprits pay the price, and I will definitely save Hogwarts from Umbridge's clutches!"
