Charlie informed Ron that he would let some of his friends go to the tallest tower at Hogwarts to pick up the dragon in the middle of the night.After that, Ron specially ran to the library to inform Maca and asked him if he would act with them at night.

But not long afterwards, Maca saw Ron with a blue face in Hagrid's room.

He collapsed on Hagrid's sofa, his hand almost swollen into a ball, and the wound was still slightly green.

"Dragon Toxin," Maca looked at his hand and said, "Are you bitten by it?"

"Oh-I don't think Norbert did it on purpose, it's just a little scared..." Hagrid looked sorry.

"I think it must be very painful." Harry also looked lingering.

"It's not just my hand," Ron whispered at this time. "Although it hurts like it's about to break. What's worse is that Malfoy laughed at me so much when he was over. Pretending to ask me to borrow books, I took this opportunity to touch my wound hard—"

Harry and Hermione tried their best to calm Ron down.

"By midnight on Saturday, everything is over," Hermione said, but it didn't comfort Ron in the least.On the contrary, he stood up from the sofa hurriedly, in a cold sweat.

"Saturday at midnight!" he said hoarsely, "Oh, bad! Oh, bad—I just remembered that Charlie’s letter was sandwiched in the book Malfoy borrowed. He must have known that we were going to take No. Uncle!"

"It's too late to change the plan," Harry said to Hermione. "We don't have time to send another owl to Charlie, and this is probably our only chance to get rid of Norbert. We have to take a risk."

"We have the invisibility cloak! Malfoy doesn't know this."

"It's okay, I'll go there too. Compared to this, Ron, you'd better go to the school hospital," Maca smiled and said, "Wait before your hands start to rot."

"Or I can make you some ointment to treat agrimony toxin."

A week passed quickly.

But that night, when Maca was standing in the corridor and saw Harry and the others, coming out from under the invisibility cloak.He saw Harry looking at him with a look of embarrassment.

"Sorry, Maca," he said, "I mean, I'm afraid I can't hold you in the invisibility cloak."

"Oh, no," Maca smiled. "You can be invisible without a cloak. Let's go! But I can't talk when I'm invisible. You don't care about me, I'm by your side."

After that, he took out a sip of Xianyin Potion.Suddenly Harry realized that he couldn't even figure out how Maca disappeared, as if there was no one there.

This is the most prominent advantage of Xianyin Potion-it can make people disappear into the sight of others in the most inconspicuous way.

"Well-let's go now!" Harry scratched his head, put on the cloak again, and hid everyone.

It was a dark, overcast night, and they arrived at Hagrid's cabin a little late, because Pepy Ghost was playing tennis against the wall in the hall, and they had to wait until he left.

Until they moved the big crate containing the little dragon Norbert to the top of the tower with great effort, they suddenly heard movement ahead.

The little lions were so scared that they almost threw away the boxes in their hands.In a panic, they seemed to forget that they were invisible, and they all squeezed into the shadow of the stairs.

Maca had to move away a few steps because he was almost hit.

He saw two dark figures fighting with each other ten steps away.A lamp flickered in the dark.

One of them seems to be Professor McGonagall.

She was wearing checkered pajamas and hairnets, and was pulling Malfoy's ear angrily.

"Containment!" she yelled, "Slytherin deducted twenty points! Wandering around in the middle of the night, how dare you—"

Malfoy retorted hurriedly: "You don't understand, Professor, Harry Potter is coming-he is carrying a dragon!"

"Total nonsense! How dare you make up such a lie! Go-I'll see what Professor Snape will do with you this time, Malfoy!"

Professor McGonagall took Malfoy's ear and left here. As he walked past Maca, he looked at Malfoy's slightly flushed face with interest.

After getting rid of Malfoy, the steep spiral staircase leading to the tower was unobstructed for them.Harry and his party had been under the cold night sky before taking off the invisibility cloak.

While they waited, they giggled at Malfoy, and Norbert moved violently in the box.

"Where is Maca? Are you still following?"

Harry suddenly thought of Maca, he looked back, but didn't move at all.Seeing this, Hermione couldn't help feeling a little worried.

About ten minutes later, four broomsticks suddenly landed from the darkness.

Charlie's friends are all cheerful people.They showed Harry and Hermione the ropes they had tied up temporarily so they could hang Norbert between them.

The four men tied Norber to the rope securely, and then Harry and Hermione shook hands with them and said many thankful words to them.

Finally, watching the four people take the box far away and disappear into the night sky.

They quietly walked down the spiral staircase, finally getting rid of the heavy burden of Norbert, and even the pace became a lot easier.

Dragon is gone, Malfoy will be locked up, is there anything more pleasing than this?

There are indeed no more happy things than this, but there are obviously many worse things than this.

As they stepped into the corridor, Filch's face suddenly appeared from the darkness.

"Oh, oh, oh, oh," Harry whispered, "we are in trouble."

They were overjoyed for a while and left the cloak on the top of the tower.Just as they were extremely anxious, a thin object suddenly covered their heads.

"Maca?" Hermione whispered in surprise.

Maca smiled bitterly at them because it was too late.At the moment the invisibility cloak was just put on, Filch had already seen him.

"Hermione, you are good at observation." He and Filch looked at each other eye to eye, but they were not busy and joked softly.

The biggest shortcoming of Xianyin Potion is just that, as long as you take the initiative to let people see it, the effect of invisibility will be completely gone.Just now Maccamming had been hiding in the shadows behind them, but Hermione had seen it for the first time.

"Oh yes, Mr. McLean!" Filch looked at him fiercely and said gruffly, "I think I should hand you over to Professor McGonagall-Professor Sprout treats students Too gentle."

Under the invisibility cloak Harry and their worried gaze, Maca followed in Filch's footsteps.He even had time to quietly wave his hand to them, so that the three little lions should not be too impulsive.

When Filch led Maca to Professor McGonagall's study on the second floor, they found that Professor McGonagall was not here.After waiting for a while, Maca realized that Professor McGonagall was followed by a short, chubby, cowering little boy—it was Neville Longbottom of Gryffindor.

"Maca!" Neville blurted out shivering as soon as he saw him, "Why are you here? Malfoy said he was coming to catch—"

"Neville," Maca immediately interrupted him, "I think Malfoy must have deliberately framed me, but it doesn't matter. Also, thank you for your concern."

After that, he turned to Professor McGonagall and said apologetically: "Professor, I'm really sorry. But please let me explain."

Professor McGonagall was obviously angry because she saw Maca in this situation again.

"Before explaining, do you have to tell me, Mr. Potter and Miss Granger, where are they now?"

Maca used his ass to think and know, it must be Neville's recklessness and confusion.

He didn’t even look at Neville, but looked at Professor McGonagall with a calm gaze, and said calmly: “That’s it. Mr. Malfoy had a rift with Harry before, so when I and Harry discussed about When he knew the dragon, he heard it. I think Mr. Malfoy mistakenly thought that we really have a dragon, but how is this possible?"

"As for what happened tonight, I'm sorry to say that it is indeed my fault." Maca said, putting a bottle of potion on Professor McGonagall's desk, "I accidentally mentioned it to Harry I have developed a new type of potion that I originally wanted to test tonight, but they seem to be interested in it."

"A new type of potion?" The anger on Professor McGonagall's face suddenly disappeared without a trace, but a shocked expression appeared, "You mean, this is the potion you invented?"

"Yes, Professor." Maca continued apologizing, "Harry and the others wanted to come out to find me, but I persuaded them to go back early. Maybe they have gone wrong with Neville."

When Maca saw Neville with a bewildered look, he couldn't help but sighed secretly-don't look at Neville's usual courage, but at the critical moment he was brave enough to be reckless, worthy of being a Gryffindor student.

And Professor McGonagall obviously didn't listen very carefully, she still maintained an incredible appearance right now!

"Mr. McLean, I want to know what is the effect of the potion you invented?" Professor McGonagall carefully picked up the potion bottle on the table and asked seriously.

After Maca explained to her in detail the usefulness, advantages and disadvantages of the Immortal Potion, Professor McGonagall immediately decided to tell Dumbledore and Snape the good news overnight.Although Maca had expected it a long time ago, he still sighed for Professor McGonagall's spirit of caring for students and school.

"So, you invented this?" Snape re-corked the Immortal Concealing Potion that he had sniffed, a rare look of surprise appeared on his face.
