London and Songjiang are eight hours apart in time. The Diana departs at 1 p.m. Songjiang time, and the journey takes two hours. It arrives in London at 7 a.m. The fact that a group of students were forced to go to the lakeside to be punished so early shows Umbridge's abnormal educational philosophy.

"Seems a bit too high-profile..." Bai Lin watched as the black-clad guards on the shore put down what they were doing and gathered in their direction. With a thought, a large patch of black mist rose from the lake, instantly enveloping the entire Diana. Several dark clouds formed in the sky, and within minutes, they would obscure the sun. This was a new skill he had created by fusing Yanyanluo's "Lost Smoke" with the black magic "Black Mist Pervasion," and he had personally tested it and found it to be extremely effective.

The next second, Bai Lin appeared without warning among the group of black-clad guards, startling them.

Apparition cannot be used within the Hogwarts campus, but that only applies to ordinary wizards. Bai Lin has already gathered the power of both chaos and order, so Hogwarts' defensive magic no longer has much of an effect on him. Moreover, since Dumbledore went into seclusion, Hogwarts' defensive power has been weakened considerably.

A beam of light, interwoven with blue and black, rapidly spread outwards from Bai Lin's position. Strangely, this light had no effect on the students whose hands were bound, but when it shone on the black-clad guards, it made them feel as if they had fallen into an ice cellar, and in less than a second, they were all frozen into black ice sculptures.

"Your mastery of chaotic power has improved again!" Yan Nishuang appeared beside Bai Lin. She was also surprised by Bai Lin's use of energy. Bai Lin had transcended the limitations of spells and even skills. His power was almost at his command, and the power of every magical element moved according to Bai Lin's will.

With a wave of her hand, Yan Nishuang summoned a white energy throwing knife that swiftly swept past the students' hands, severing the ropes binding their wrists.

Bai Lin nodded to her. He glanced around and recognized a familiar face among the students: Eddie, a student he had previously thought highly of. Although Eddie didn't have much screen time in the original story, Bai Lin had always felt that he possessed magical talent no less than Harry's.

Eddie had lost a lot of weight and grown taller. His body and face were filthy. The mornings in Britain in October were still quite cold, but he was only wearing a thin undershirt. There were whip marks on his arms, indicating that he had suffered a lot recently.

Just as Bai Lin was about to grab Eddie and make him lead the way to get revenge on the old witch Umbridge, a shout suddenly came from the reeds not far away. Bai Lin was somewhat amused and turned around to see a group of students rushing out from the tall, withered reeds. The leader was none other than a familiar face: Harry with his black-rimmed glasses and the dashing Cedric. On the chest of their robes were badges with the letters "DA".

"Professor Kaelin!" A cry of surprise came from behind Harry. A girl rushed out and excitedly ran to Bai Lin, hugging him tightly.

"Hermione... it's a little embarrassing to be recognized so easily..." Bai Lin looked at the little girl in front of him and shrugged at Yan Nishuang.

Harry's expression was a mixture of surprise and delight. He exchanged glances with Eddie and the other classmates, and they also saw the dozen or so black-clad guards who had been turned into ice sculptures. They quickly learned what was going on. Apart from Dumbledore, the strongest magic professor at Hogwarts had returned. This omnipotent man was like a blazing sun, capable of melting any difficulty or enemy on the spot.

Bai Lin patted Hermione on the shoulder. Although such hugs were common in Western culture, it was still somewhat embarrassing for her to be intimate with another girl in front of Yan Nishuang, especially since she was his student…

Bai Lin stepped forward and patted Harry and Cedric on the shoulder. Cedric was also very excited, grabbing Bai Lin's hand and whispering, "Professor! Long time no see!"

"Is the Room of Requirement still safe? You must have a lot to say!" Bai Lin asked Harry, noticing his hesitant expression.

Harry was clearly startled again, not expecting Bai Lin to expose his hideout so easily. After the entire school was being persecuted by Umbridge, and he realized Umbridge's evil plot, he led the students who were willing to resist to hide in the Room of Requirement. They had been there for a month or two. Although Umbridge was searching for them everywhere, he had not been able to find this hiding place. He thought it was safe there, but Bai Lin's revelation made him realize that many people actually knew about the Room of Requirement.

"Let's talk about it when we get back!" Hermione quickly smoothed things over. She clearly trusted Bai Lin far more than Harry did. In fact, Harry didn't know why he always felt a bit distant from Bai Lin. Perhaps it was the wariness of a chosen one of another plane's intruder...

They successfully infiltrated Hogwarts through a secret passage. Along the way, Hermione quietly briefed Bai Lin on the current state of Hogwarts, which turned out to be even worse than in the original story. Umbridge had dismissed many teachers, including Professor Pomona Sprout, Professor Flitwick, Mrs. Pines from the library, and even the castle caretaker, Filch.

The library was sealed off; all the books were said to have been moved. The castle's security had been replaced by strange black-clad guards. No one knew where these guards came from; they seemed like robots, appearing out of nowhere, obeying only Umbridge. Hogsmeade Village was also completely under Umbridge's control. Trains stopped running, and Hogwarts was now completely isolated from the outside world; the students had no way to escape.

In the past few months, a large number of students have gone missing. Only a little over a hundred have managed to hide in the Room of Requirement. Although these students are now somewhat safe, their daily needs for food, drink, and sanitation are still very demanding. Fortunately, Dobby, who has returned to work in the Hogwarts kitchen, smuggles food to them every day. Otherwise, these students will starve to death.

Yesterday, Dobby failed to deliver the food on time, so Eddie took a few students and risked going to the kitchen to check. They were caught red-handed by the guards in black, though Umbridge didn't show up. The guards gave each of them a few lashes and then planned to subject them to waterboarding. Eddie had no idea what they were going to do; he couldn't very well just let them drown…

"Umbridge is conducting experiments in the Hogwarts dungeons!" Hermione whispered to Bai Lin, "I think she's taken all the missing students to her lab!"
