Harry, Ron, and Hermione looked at each other.

"So," Ron said hopefully, "you just picked up something from the library and took it over to fool them?"

Fred said with a straight face, "I'm sorry to disappoint you, but we are still trustworthy. But our knowledge of the Black Lake is limited. If we go too deep, we will be driven out by mermen with forks, and their tamed pets are not friendly enough--"

"It's Grindylow." George looked at Harry with a puzzled look and explained.

"Red hats, Kaba, ghost face grass... We dare not go too deep, for fear of being hung up and beaten by mermen. But sooner or later we will draw a map of the Black Lake. This is one of our plans, and it will be completed before graduation." Fred said.

George looked at him strangely, "When did we come up with this plan?"

"Just when we were talking. Do you want to join?" Fred asked.

"That sounds good," George said with a smile. He looked at the three people who were stunned. "Harry, your father and his people have done everything. There is no point in repeating it. It is better to find a new way. Anyway, we are in the sixth grade this year, and we must leave something behind."

The twins left. Before leaving, George reminded them, "By the way, Harry, if you go to the school hospital at this time, there will be a surprise waiting for you."

The three stared at their backs and fell into deep thought.

"We should ask for a map, even an incomplete one." Ron suddenly said, "It will definitely save a lot of trouble."

"We can do it ourselves." Harry said without thinking. It is still a long way from February.

Hermione counted on her fingers, "Except for us, including Cedric's group and Ugadu, half of the teams already know the information of the second project. It is hard to say about the other three schools-" "

Maybe Durmstrang should also be counted." Ron said sarcastically.

Hermione's eyebrows were raised.

"Sorry, I didn't make it clear - I meant that Karkaroff would definitely find a way to cheat," Ron said. "I have confidence in him."

Harry couldn't help laughing.

"We'd better go to the hospital ward and see the surprise Fred mentioned..." he suggested. When they arrived at the hospital ward and turned the corner, they vaguely heard more than one familiar voice.

"Professor Happ?"

"Sirius?" Harry said in surprise.

They quickened their pace and saw that the door of the intensive care unit was open. Sirius stood opposite the door, leaning against a table, fiddling with his wand, his eyes staring fiercely in one direction.

Then, Moody's gruff voice came from inside, "If you want to fight, you'd better go outside! I don't have a wand in my hand, and I'm missing an eye..."

"Your eye is soaked in potion, Professor Moody, who told you to complain that it doesn't work as soon as you woke up." Felix said in a gentle voice.

"I'm telling the truth! And my wooden leg is almost half an inch shorter. It must be that despicable guy who did it!" Moody said angrily. This was related to the treatment he had just received from Felix.

Felix sighed. The examination just now was not smooth because the patient always subconsciously resisted. So he couldn't help but try the skills he learned from the Dementors. As a result, Moody looked quite depressed after the treatment. His way of showing "depression" was to be indiscriminate and rude to people.

Felix raised his head and looked at Harry, Ron and Hermione standing at the door, and waved to them.

They walked into the room and were surprised to find that it was very lively inside. Opposite Sirius, Snape, wearing a black robe, stood on the side like a black blood-sucking plant, confronting Sirius with an indifferent expression, and each other's eyes were full of contempt.

Snape's hand was hidden in his sleeve. Harry guessed from his posture that he should be holding his wand.

This also solved a puzzle: Harry didn't think Sirius would have a conflict with Professor Happ. If he remembered correctly, in Hagrid's hut in the third grade, Sirius had personally revealed the secret that he was easily caught by the professor. He looked quite reluctant at the time.

In addition to these people, there were two more people in the room, one was Madam Pomfrey, and the other was Neville.

Neville was shrinking in the chair as much as possible, which was not easy, because his height had grown at least half a foot compared to last year, and he was comparable to Ron. When Harry walked over, he had a sad face and said aggrievedly in a voice close to a whisper: "I just wanted to come over to give a bouquet of flowers, like yesterday... But Professor Moody woke up, and then Madam Pomfrey called Professor Happ. After a while, Mr. Black suddenly appeared and said that he had something important to discuss. Halfway through, Professor Snape also came over."

Very good, Harry thought, Neville accurately restored the order of these people in the room, and he could imagine the general process of the matter.

He looked around. Professor Heppe was wearing a rare white coat. Was he imitating a Muggle doctor? Madam Pomfrey was standing not far from him. She was holding a vertical board and recording quickly. Harry continued to look over there, and then his sight seemed to be stung, passing over the conspicuous large glass cup next to the bed - Moody's magic eye was immersed in blue liquid, and from time to time it turned a circle like a convulsion.

Ron made a disgusted sound.

"Harry." Sirius came over and hugged him tightly. He whispered, "I got the news from Hagrid that Moody is injured now, so come over and try -"

"What's the problem?" Harry asked in a low voice.

Sirius curled his lips in Snape's direction with disdain. Snape pretended not to notice and said slowly: "I have been authorized by the headmaster. If Mr. Alastor Moody still hopes to complete this year's teaching work, then... out of concern for my colleagues, I will temporarily take over a few classes while he is recovering."

Sirius immediately looked at Moody and said with a smile: "Alastor, I suggest you hide for a while..."

He suddenly realized that he had touched the taboo of Mad-Eye Moody and was about to face the rage of a volcanic eruption. He quickly stopped, but it was too late.

Harry swore that he had never seen Moody's face so distorted. Every cut on his face miraculously expanded and shook with disgust. Moody roared loudly: "Ha! Do you think I dare not see people? After being manipulated like a puppet by Voldemort and a Death Eater for several months? What do you think I will do? Hide like a coward and cry? I tell you, dream!"

Sirius's face suddenly became as pale as paper.

Moody's only eye was wide open, staring at Sirius. Harry even felt that Moody's eye was more terrifying than the fake eye in the bottle. Even his empty eye socket was nothing compared to the anger that burst out of it.

He pointed at the empty bed next to him, "Do you know what the first thing Barty did after he woke up? He went to the Ministry of Magic and turned himself in! He wanted to tell everything and atone for the mistakes he made!"

He pointed at his own broken nose, spit flying, and roared, "I will do what I promised Dumbledore. Not only that, guess what?" He looked at the distraught Sirius, "I will tell everyone what happened to me, but being a student is not enough..."

He said with a grim face, "I will tell everyone that Voldemort is still alive, or at least not dead yet."

Dumbledore's heavy voice came from outside the door, "Alastor..."
