Head of Teaching at Hogwarts

Ten minutes later, in the corner of the long corridor where the Christmas basilisk attack occurred.

Harry, Ron and Hermione were huddled in the invisibility cloak. They kept silent in agreement and just kept looking around the corner.

The temperature at the end of December made them shiver, and they could only huddle together in the corner to keep warm.

Ron felt that his whole body was shaking, all his pores stood up, and his upper and lower teeth kept fighting. He lowered his voice and trembled and said: "Is it possible that Professor Russell will not come tonight? How about we Let’s go back first?”

"Just wait a little longer," Harry said patiently.

Suddenly Hermione gestured towards them, and the tacit understanding of participating in the Wizards League Glory Competition made them quickly quiet down, as if they were conducting a squatting ambush.

Following Hermione's eyes, they saw a tall voice approaching the corridor in the moonlight.

It's Russell!The three of them instantly entered a latent state.

At this time, Russell was smiling, thinking back to the report Illidan had given him just now - "Three little wizards wearing invisibility cloaks slipped out of the Gryffindor lounge."

Without any hesitation, Russell immediately judged that this was definitely the trio of Harry, Ron and Hermione, and then followed them all the way here.

There was no difficulty for Russell on how to track and monitor the little wizard protected by the invisibility cloak.

Legend has it that Harry's invisibility cloak can even help the user escape the pursuit of death, but it cannot escape some simpler and more basic tracing methods.

For example, Russell's house elf Illidan judged by the sound of footsteps and breathing that three little wizards left the Gryffindor lounge wearing invisibility cloaks.

For another example, Russell is currently using a magic spell - Quick Reveal (Thermal Imaging Limited Edition).

The Quick Manifestation spell allows wizards to see the wizards protected by the Illusion God Curse and the Invisibility Cloak. However, Harry's Invisibility Cloak is one of the three legendary Deathly Hallows. The ordinary Quick Manifestation spell is natural. It's impossible to see through, but Russell's Quick Reveal (Thermal Imaging Limited Edition) is not one of them.

In order to study this magic, Russell personally went to a military base in a certain country in the Middle East and borrowed several military thermal imaging cameras.

Compared with the ordinary speed display, both the scope of application and the strength are much higher, and it is especially suitable for use at night.

But unfortunately, the basilisk, like snakes, is a cold-blooded animal. The body temperature of the basilisk is always consistent with the surrounding environment, so Russell cannot directly find the basilisk through this magic.

Russell took out his wand and started tapping on the wall, refusing to let go of any brick, and he kept getting closer to the trio inside the invisibility cloak.

Russell kept approaching them, with a playful smile on his face.

The trio inside the invisibility cloak almost stopped breathing, nervously looking at Professor Russell who was approaching.

Through his quick display (thermal imaging limited version), Russell saw that the thermal infrared image in the corner began to shake continuously. At about the height of the head, there was a place where the temperature was rising rapidly.

Under the invisibility cloak, Harry felt himself shaking nervously, and so did Ron and Hermione next to him, especially Hermione. Not only was she shaking, but in the moonlight he saw Hermione's entire face turn red. , every time I take a breath, it feels hot.

Fortunately, Russell didn't seem to notice them and passed them by, choosing a stone slab higher up to knock on.

About 10 minutes later, Russell finally left the corridor.

"Huh -" Harry couldn't help but let out a long sigh of relief under the invisibility cloak.

"Did he notice?" Harry asked.

"Probably not." Hermione judged, but not very confidently.

"How about we go back." Ron regretted coming here.

"No, we must know whether Professor Russell is a good guy or a bad guy!" Hermione was unusually determined.

Then the three people almost huddled in the invisibility cloak and walked out of the corridor step by step. Then when they came to the corner, the three people suddenly froze.

In front of them, in addition to Professor Russell who had just left, there were also Professors McGonagall, Professor Flitwick, Professor Sprout and Snape.

Russell was leading them forward while saying in his mouth: "I just discovered that there is something in the corridor where the attack was that we didn't notice before!

I figured if there was any secret room or attacker, it must be around here. "
