Half an hour later, after confirming that all the students were gathered in the room for requests, the professor who had little combat power arranged to host the duel and watch the students, not allowing them to leave or something happened, everyone, including Harry Potter, who was temporarily recruited by Dumbledore, gathered at the entrance of the room.

To be fair, like now, the most famous white wizard in contemporary times, the principal of Hogwarts, the official of the Ministry of Magic, Professor Hogwarts, the heir of the big family, half giants, and a large group of men gathered in an abandoned women's bathroom. This was so beautiful that people dare not read it.

However, no one cares about this now.

Everyone stared at the only boy among the crowd, Harry Potter.

In front of him was an ordinary pool. Unlike several other pools, there was a small snake engraved on the side of the copper faucet of this pool. If it were not known in advance, it would be easily ignored.

"Harry, treat the snake as alive, and then talk to it, and say open it!" Sirius patted Harry's shoulder and encouraged.

Harry, who was called by Dumbledore's Phoenix, nodded in confusion and walked forward obediently, stared at the carved little snake, trying to imagine it as a real snake.

"Open it!" he said, everyone understood it, it was obviously not a snake accent.

"Potter, focus, we let you treat it as real!" The crazy-eyed man looked straight at Harry.

Seeing the magic eyes in the mad-eyed man's eyes staring at him, Harry shivered and looked back at the godfather Sirius and Remus. Seeing the comfort and encouragement in their eyes, Harry mustered up the courage to nod, turned his head to look at the snake, forcing himself to believe it was alive. Harry thought that if he shook his head a few times, the swaying candlelight would make the snake look like it was moving.

"Open!" he said.

This time, everyone heard no longer English, but a strange hissing sound from his mouth. Suddenly, the dragon head emitted a dazzling white light and began to rotate rapidly. Then, the pool also moved. They watched the pool slowly disappear from their sight, revealing a very thick water pipe that could allow a person to get in.

No one spoke, and everyone except Ning Yuan was afraid of hissing for a moment when they heard the hissing. After all, Voldemort's characteristic is so famous, and even the hissing of reptiles, even if Harry made it, had a cold meaning of a cold-blooded animal.

Ning Yuan saw the mad-eyed man's magic eyes spinning rapidly, and Snape also covered the position of the black demon mark with his right hand. His face was terrifyingly dark. This double-sided spy had seen Voldemort use the snake to control the snake to swallow the opponent's corpse.

I have to say that knowing is different from seeing with my own eyes or hearing with my own ears.

Even though they knew the "truth", at this moment, many people still felt that Harry's thin figure overlapped with Voldemort for a moment. Except for the heartless Sirius, Lupin, Ning Yuan and Dumbledore, the others all looked at Harry with complicated eyes.

Of course, looking at the praise from the godfather, the shy smile revealed on Harry's face and the smile around him, Dumbledore quickly threw the fear in his heart behind his head. It has to be said that Dumbledore's prestige is still good.

"Okay, since the entrance has been opened, then Hagrid, please trouble you." Dumbledore clapped his hands, attracted everyone's gaze, and ordered Hagrid, who seemed particularly excited.

Hagrid was particularly excited since yesterday when he learned that there was a real murderer who killed Myrtle back then, who had been pricked up his magic wand and fired him from school. Unlike the joy he often saw when he cherished legendary magic creatures, Hagrid now is more angry with the real murderer after being upset.

An honest person does not get angry does not mean that an honest person has a good temper. An honest person who gets angry is also a half-giant, which is even more terrifying.

Hagrid, who was ignited with anger, had it not been stopped by someone yesterday, the angry half-giant would have almost rushed to the secret room to fight with the snake monster, or took out all his savings and planned to buy a rooster in order to revenge the damn snake monster that ruined him.

Hagrid, who came out of the sound, grinned and ran out of the women's bathroom quickly. He quickly carried in one wooden box that looked not big. The boxes were made of wooden, with traces of magic being cast.

Soon, ten boxes were piled up in the already crowded women's bathroom.

The total number of people participating in the operation this time was Ning Yuan, Dumbledore, Snape, Harry, Sirius, Remus, Crazy Eyes Moody, Hager, and several others, such as Kingsley and other members of the Order of the Phoenix. They are now drinking compound decoctions and pretending to be Dumbledore and some appear at the duel club.

After Hagrid moved the box in, without Dumbledore's instructions, the crazy-eyed man Moody had already walked up and began to explore the passage in front of him with his magic eyes.

"It's very deep, very deep, almost far from the ground, but there are no signs of life except for a few mice. It's temporarily safe!" Soon the crazy-eyed man Moody said about the award situation.

Dumbledore, who was worried, also took out his wand and began to check the passage to see if there was anything wrong. After another half a minute, Dumbledore, who had not found anything, confirmed that he was safe.

"Very good, are all kinds of things ready?" Dumbledore looked at everyone seriously before setting off.

No one has a pair of glasses with magic defense, so it is guaranteed that even if something unexpected happens, the eyes of the snake monster will not die immediately and will not be petrified.

The chemical agent that dispels petrochemicals ensures that they can resume the battle immediately if they are petrochemicals.

Relieve potions to ensure that the toxin can be relieved immediately after being damaged by the snake monster venom and increase the rescue time.

A universal antioxidant can be used with a moderated agent after poisoning to reduce toxins and at least wait for rescue.

There are also a lot of other miscellaneous things that are placed in the space bags around everyone's waists, and can be used immediately whenever they need them during battles.

After checking what he was carrying, everyone looked at Dumbledore, "After the inspection, everything is ready, professor!"

"Very good, I'll go down first, and then go down one by one in order. Harry is in the middle, and Hagrid finally, do you understand?" Dumbledore looked at everyone.

Dumbledore, who received the reply, nodded, held his wand tightly and walked to the passage, "See you later." After saying that, he put his legs into the tube, and after letting go, he quickly slipped down and disappeared at the entrance of the passage.

According to the order everyone planned, Ning Yuan was the second person to go down, so he waited for a while and waited for him to think Dumbledore should have gone down to the end before he jumped into the pipeline.

It was like a roller coaster or a twisty slide like an amusement park, and it rushed down a dark, sticky, endless slide. He could see many pipes breaking in all directions, but none of them were as thick as this pipe. The pipe was twisted and turned, twisting and twisting, and the slope was steep and down.

After a while, just as he was thinking about how far he was, the feeling of crashing into a cotton ball instantly wrapped around him as he was falling rapidly, but he stopped in mid-air from his rapid decline.

When his eyes adapted to the darkness, he found that he was caught by Dumbledore with magic, and it was obvious that it was the end.

"Thank you, professor!" Dumbledore waved his wand, and the force field around Ning Yuan disappeared, and Ning Yuan was down-to-earth again.

This is a dark place. Apart from the light of the magic light ball created by Ning Yuan with his magic wand, he could hardly see his hand and could only see a deep and dark tunnel. He didn't know where he led.

Just as he followed the magic ball of light to check the place, the next few people fell down one by one, and were caught by Dumbledore one by one, then walked to the side to prevent the next person from colliding together when he fell down.

Later, as the ten magic boxes fell down safely and were caught by Dumbledore, Hagrid was the last one to pass through the pipe. Fortunately, the pipe was not small and could just accommodate Hagrid's huge size, otherwise he would have to stay on it.

"We must have been several miles deep under the school," Ning Yuan said, his voice echoing in the dark tunnel.

"It's probably at the bottom of the lake." said the crazy-eyed man. He narrowed his only eye and looked at the dark and sticky walls around him with his magic eyes.

"Very good... It seems that everyone is fine, so let's continue!" Dumbledore said, pushing his glasses.
Chapter completed!
