#486 - I solemnly swear that I am up to no good!

If Professor McGonagall had not added this last sentence, none of Lin Xia and the others would have doubted that Hogwarts was unsafe.

Since when did the professor need to emphasize the safety issues of Hogwarts?

After Professor McGonagall left, the others looked at each other, and Ron took the initiative to ask: "What should we do now? Should we return to the laboratory first, or run to the Great Hall?"

He volunteered his thoughts, "I would rather go to the Great Hall. I believe all the young wizards are in the Great Hall discussing Professor Trelawney's fainting. No one knows what happened after we left."

I don’t know what happened, but I have already heard the most crucial prophecy. Asking about what happened later is just like eating spectators and waiting to see how the rumors will evolve.

Lin Xia shook her head and said, "I'm not going to the auditorium. You can go if you want. Ron, remember to try to make the [Pitch Black Potion] again today. Try to make it every day. With your progress, you may be able to make it within a month."

If it could be made in a week, Ron might be interested.

But when he heard that it would take a month, he immediately lost interest and became listless.

Please, Christmas is coming soon. On the eve of the holiday, everyone will just get together excitedly to discuss where to go and how to celebrate the holiday.

Who would want to stay in an empty laboratory, doing experiments alone? He was not a research maniac, and he was not very interested in potions.

However, the next second, Lin Xia seemed to have guessed his thoughts and smiled gently: "You may not know the value of that bottle of potion. Draco did not return home all night yesterday because he accompanied Professor McGonagall to test the potion.

This potion is very useful for high-level infected people. Although it cannot awaken their consciousness, it is easier to kill them than before. A conservative estimate is 100 gold galleons. "

Ron: "Oh, one hundred gold Galleons... Wait, what did you just say? That bottle of potion is worth one hundred gold Galleons!"

His eyes widened, and he looked not only at Lin Xia, but also at Hermione and Harry.

Hermione and Harry were also shocked.

A bottle of potion that costs one hundred gold galleons... this is undoubtedly a high-level potion!

Normally they couldn't afford this kind of potion, but now they could actually try to make it?

Moreover, looking at the materials of the pitch-black potion, no rare materials are needed, so it can be made over and over again.

Lin Xia said: "This is just a conservative estimate. The actual value may be even higher. I'm just telling you in advance."

Ron immediately pulled Harry into the laboratory.

Stop talking, stop talking about anything. He just wants to make the pitch-black potion now.

Harry struggled and said, "Ron, don't hold me so tightly, I still have to train, I still have to train..."

After the two ran away, Hermione looked at Lin Xia and asked, "This bottle of potion is so valuable, why don't you try to make it yourself?"

Lin Xia shook her head: “Each potion has its own characteristics, and people who match the characteristics are more likely to make it successfully.

Draco has already written down all the precautions, so as long as he sticks to it, he will succeed, and the production process...well, weird medicine is so abstract.

Lin Xia said, "He must be too tired. He should take a day off to rest today. You can ask again tomorrow. You can also talk to Ron. He has a talent for making black potions."

Hermione wrinkled her cute little nose. Ron suddenly became so powerful that she was a little uncomfortable with it.

-

Lin Xia did not go to the laboratory, but went to the dormitory to complete today's daily training first.

She had a feeling that she would be extremely busy at night and might not have time to practice.

The power from the Slytherin locket flowed through her body continuously. Lin Xia felt that her right heart was becoming stronger and stronger, which caused her body to bear a greater load every time she adjusted the resonance frequency.

In short, she was bleeding more than ever.

But this is a good thing, as it gave her another blood transfusion invisibly.

The newly grown blood vessels and the blood produced can better adapt to this new body, and it also gradually becomes stronger.

After the training was over, Lin Xia glanced at the window outside the tree house and it was already three o'clock in the afternoon.

She first checked the illusory snail used for surveillance, and found that after putting on another larger layer of forbidden magic box, the picture frame imprisoned inside no longer moved. She didn't know whether it sensed danger or felt something else.

Lin Xia stared at the box and said softly, "It's better to be honest recently. I don't have time to deal with you yet."

After finishing her daily training, Lin Xia went to the laboratory. Draco did not come out, so she ran out of Hogwarts to find the Weasley twins who were practicing on the Quidditch field.

As usual, the twins slacked off during training, cursing the hellish training that didn't allow them to rest.

But recently they apparently have a new pastime - staring at Ronan from time to time.

They looked at Ronan as if he were a thief who walked into their yard openly, staring at him hungrily.

As soon as Ronan makes any unusual move, they will be the first to jump out and accuse him of crimes.

When Lin Xia found the twins, she discovered that Harry was always with Ronan. The two of them talked from time to time, and the atmosphere seemed very harmonious.

Suddenly, two balls of sparks exploded before her eyes. George and Fred said in unison, pretending to be sad:

"We really don't have any charm."

"Two living people that big are in front of Lin Xia."

"She actually ignored us and went to see Harry and that damn pretender!"

George sighed heavily: "Losing charm is indeed a terrible thing."

Lin Xia came back to her senses and said with a smile: "George, Fred, if you dare to set off a bunch of fireworks in front of Wood, I guarantee that you will become the most conspicuous people in the audience."

She added: "Well, it was conspicuous to be chased and beaten by Wood."

George shrugged. "I don't dare to mess with Wood. I just played a little prank last time, but damn Wood didn't let me go for ten consecutive days, even on weekends, and woke me up at five in the morning."

Fred: "We've received so many dorm complaints about this, and even our roommates are looking at us like they want to eat us."

George and Fred said in unison: "We don't want to go through this horrible experience again!"

Lin Xia didn't argue with them. She cast a confusion spell and a shielding spell around her and made her purpose clear: "I want to borrow the survival map from you."

George and Fred just glanced at each other, and George said in a long tone: "Dear Ms. Lin Xia——"

Fred shook out a piece of parchment like a magician, and the yellowed corner faced Lin Xia, like a tattered piece of rag.

"Are you sure you want to borrow our lovely first love?"

Lin Xia took the parchment and flicked it with her fingers, which made clear and pleasant sounds like the sound of gold galleons colliding with each other.

Spider-web-like ink lines immediately appeared on the parchment, and George and Fred silently put away the gold Galleons in their sleeves. The smiles on their faces deepened, and they looked at Lin Xia as if they were looking at a glowing God of Wealth.

Lin Xia poked the parchment with her wand again and spread it out. The spider-web-like ink lines only outlined a border, and the parchment did not reveal its true function.

George restrained his smile and said seriously: "Although you already know how to use it, I still have to say it. Remember to tap your wand three times and say 'I solemnly swear that I will do no good', and you will see everything you want."

Fred also looked solemn: "I'll give you a piece of advice, don't use it in the corridor on the east side of the fifth floor--"

Lin Xia looked over there with a puzzled look. Is there something special there?

George revealed the suspense: "--Unless you want to have a cheek-to-cheek dance with Snape's greasy head."

Lin Xia looked down at the parchment again. The route of the parchment, which had just been activated by George, had now fully emerged, and the densely packed little dots were swimming like countless tadpoles.

Point your finger at a building or a classroom, and everything around it will be quickly magnified.

The name of someone labeled "Old Bat" was echoing in the corridor on the east side of the fifth floor, near a bathroom.

Lin Xia's fingertips brushed across a deforming spiral staircase, and suddenly she stopped and saw the name "Peter Pettigrew".

“I might need to borrow it for a longer period of time,” she said.

The latest novel is published first on Liu9shuba!

George and Fred both deliberately swung their sleeves, and the gold Galleons hidden in them made a crisp and pleasant collision sound.

Lin Xia stretched out her hand and shook hands with both of them, and another large sum of gold Galleons fell into their wide sleeves.

George said, "You can borrow it for a week if you want."

Fred: “We’d be happy to lend it to you.”

Lin Xia didn't say it wouldn't take so long. Who knows if he can still find Peter Pettigrew after he comes back.

When she was looking for the mouse Banban, she didn't think of the Marauder's Map because the Marauder's Map was not easy to use to find people.

Such a small piece of parchment not only includes all the buildings inside Hogwarts, but also many secret passages, and even the names of the students and professors in the castle.

These characters are too densely packed, like fly dots, and are not easy to use to find people.

But she just saw Peter going to a secret passage on the third floor, and Lin Xia suspected that that might be Peter's recent residence.

After getting the Marauder's Map, Lin Xia went to find Harry again.

Communicating with Harry was much smoother than communicating with the Weasley twins. She just made her request, and Harry took something from his retractable ring and gently touched Lin Xia.

Lin Xia took it calmly. It had a texture like silk, or like an invisible flowing water, soft and smooth.

Harry said hesitantly, "Do you want to go on an adventure?"

Lin Xia nodded: "I have this plan."

Her answer was so frank that Harry didn't know what to say.

Harry: "I hope everything goes well for you."

Lin Xia smiled and said, "Absolutely."

"Harry!"

Someone called Harry's name not far away. Harry turned around and answered, then looked at Lin Xia again, took a deep breath, and said firmly: "If you need any help, you must tell me, and I will help you."

Lin Xia smiled gently: "Thank you, Harry, your words are enough."

Harry saw her smile and was attracted by her gentle temperament. He couldn't help but wonder: If my mother were still alive, would she be like Lin Xia - outstanding and gentle.

Unfortunately, there is no if.

Anything in the world that you want to recover is destined to be irreversible.

-

At six o'clock in the evening, Lin Xia was waiting in the laboratory with his eyes closed.

She was recalling her research process on the wand binding process, waiting for the paper release conference to be held in two days so that she could face the questions from the jury.

The production process of the binding wand is relatively easy, and the press conference does not need to answer the production process in too much detail. Lin Xia thought of some questions that would be difficult for people to answer, but she could quickly find ways to answer them.

Suddenly, a door opened, revealing a strange fragrance.

Lin Xia just took a sniff and the "Nine Heavens Mysterious Yang Secret Record" in his body started to operate spontaneously.

She couldn't help but frown.

Looking up, Draco came out. The "Purple Gold Mysterious Record" on his body was also running spontaneously, so he was not disturbed by the fragrance at all.

Lin Xia's eyes narrowed slightly, and Draco looked very excited.

Perhaps even he himself did not know how strong the evil god's whispers were contained in the potion in his hand. If even a little bit of it leaked, even if the toxin was not aimed at normal wizards, they would feel itchy skin and suffer from poisoning.

Draco handed Lin Xia two bottles of potion and said quickly: "After I entered the laboratory, the inspiration for the weird medicine in my mind was triggered. I just adjusted some postures and magic plants, increased the proportion of black bugs, and made an enhanced version of the 'Pitch Black Potion'!"

Lin Xia immediately asked: "What are the effects of the enhanced version?"

Draco suppressed his excitement and said, "The potency is almost 1.5 times as strong as before. I also specially enhanced the spread of the fragrance. You don't have to drink the potion. Even smelling it can make the polluter feel uncomfortable."

Lin Xia thought for a moment and said, "Don't tell the school about this enhanced version of the medicine yet. Let's use it first."

Draco nodded. "That's what I thought, too. I don't want them to think I'm too much of a genius and lock me up in a lab doing experiments all day."

He turned to look at the window and frowned: "It's already dark, can we still make it?"

Lin Xia: "I have checked out a secret passage that will take us directly to Hogsmeade Village in half an hour. It's still early."

She felt that Draco was too excited to remain calm, so she asked him to practice for a while so that he could focus his thoughts.

So Lin Xia and Draco officially set off at seven o'clock in the evening.

They put on invisible hoods and opened the parchment in the wide cloak. Lin Xia tapped the parchment three times with her wand: "I solemnly swear that I will do no good!"

Under the bright lights, the panoramic map of Hogwarts appeared on the parchment like a spider web. Lin Xia deliberately zoomed in on the third floor and went up through the Marauder's Map instead of taking the stairs.

With the parchment, every action of the Marauder's Map can be predicted, and it is not slower than the magic elevator. (End of this chapter)
