After Potions class, Ron and Hermione tried to ask Harry how he had made such a perfect potion of living hell, but Harry laughed and pulled the two of them away. There's still a bombed-out Malfoy in the classroom, and now isn't the time to talk about that.

Harry's trio made their way to the table in the cafeteria and sat down in a place where there weren't many people around.

Seeing that the students next to him were not paying attention to him, Harry said to Ron and Hermione, "I've got something good for you to see. ”

Harry then took the dirty old Potions Making textbook out of his bag and placed it in front of Ron and Hermione.

When Harry flipped to the page where he had just made the Living Hell Potion, he pointed to the notes in the book and said to the two good friends beside him, "You see, I just followed the method described here, and that's why I made the Living Hell Potion perfectly. ”

Ron looked at the dense small print on the original blank space of the textbook, and looked envious.

Seeing Ron's expression, Harry knew what he was thinking, so he said to him, "I can lend you this textbook at any time, buddy." ”

"Really?" Ron looked at Harry in surprise, afraid that Harry would regret it the next moment.

"Of course it's true." Harry nodded.

"Wait!" Hermione, who was on the side, interrupted the brothers' conversation, "You just followed what was written above without confirming that they were not abnormal?" ”

"At least practice proves that it is written correctly." Harry nodded and replied, "Whether it's the method of juicing the Sleepy Beans, the method of stirring, or the prohibitions, it's all right. ”

"You haven't even thought about what if something happens?" Hermione said to Harry with a dark face.

Harry had obviously not thought about this question, and just said something like "Isn't this a success?"

At this point, Ron said, "These are just tips to increase the success rate, and even if there is danger, it is not too bad." You see, Malfoy was just blown up and blackened in the face. ”

At that moment, a small soft hand rested on Harry's right shoulder, and a red head rested on his left shoulder, rubbing Harry's face at the same time.

Ron seemed to have a severe cough, and his unusual coughing could be heard throughout the cafeteria.

Ginny ignored her sixth brother, who was about to cough up his lungs, and said to Harry in a panic, "You've been doing what someone else has written in a book, Harry? ”

"It's not the same journal," Harry said, patting Ginny on the head, "it's just a plain little trick from an ordinary textbook. ”

Then Harry ignored his buddy's coughing and pointed to the dense letters on the book and said, "You see, there are obviously two people's handwriting here, and judging by the content, they should not know each other. If this were a dark magic item, then the person making it wouldn't have had to put so much effort into it. ”

"But you did what it said?" Ginny asked worriedly.

"Yes," replied Harry, "and I didn't get confused or ordered the whole time, and I was awake the whole time. ”

"Then I'll have to check this textbook well." Hermione said.

It was at this moment that a rich dinner appeared on the table.

Harry pointed to the dinner and said, "I think we should fill our stomachs before examining this textbook." ”

After Harry and the others had finished dinner, they went to the fifth floor, found an empty classroom, and went inside.

Harry and his party lit the candles in the classroom, then found a table and placed the old Potions Making textbook on the table, around which Harry, Ron, Hermione, and Ginny gathered.

Four of you, look at me, I'll look at you, and when everyone was ready, Hermione raised her wand and pointed at the old textbook.

As a result, nothing appeared, nothing changed, the textbook was still so tattered and old, not even the stains on it had changed.

Harry shrugged his shoulders and said, "Okay, it looks like it's fine, it's an old textbook indeed." ”

Then Harry looked at the relieved people next to him and said to them, "Why don't we see what's written in it?" ”

Ron and Ginny immediately nodded curiously, and Hermione, after thinking for a moment, overcame her hunger for knowledge over her worries about the unknown textbook.

So Harry and the four of them began to read the old and magical Advanced Potions Making textbook in the empty classroom.

Hermione pulled out a piece of parchment and an automatic quill and began to sort through the notes in her textbook.

There were two people who wrote notes in the textbook, the first one with an obvious scribbled handwriting earlier, and the second one with a somewhat strange handwriting later.

Basically, where the first person has a writing, there is the second person's research experience and praise on the side. In some places, the second person writes a lot of strange research.

At this time, all four of them had a question in their hearts - who was the person who scribbled on this textbook?

In the textbook, in addition to the tips for making potions, there are many small curses and small magic invented by the first person written in scribbled handwriting, and next to these curses and magic, there must be a second person's comment on these curses and magic.

For example, next to a curse that can make people's toes grow wildly, the second person wrote "A must for old drivers" that made Harry scratch their heads.

"Maybe it's better to step on the gas and brakes?" Ron, who drove the family's flying car, said.

"Huh?" It was as if Harry had discovered something.

"What's wrong, Harry?" Ginny asked, looking up.

Harry pointed to the spell written on the blank page of the textbook and said, "I know this spell, Sirius taught me. ”

"Upside down Admiralty?" Ron said confusedly, "Looks like you've used it on Malfoy before." ”

Hermione pointed to the two lines in the book and said, "I think you'll remember this next time you use this spell." ”

Harry looked over and saw the second person writing on the side:

"Danger! If you are not careful when releasing the spell, you can break your neck! ”

"Anyone who uses this magic on a girl will be sentenced to death!"

"Maybe Sirius and Lupin should know something." Harry said.

Then they flipped through a few more pages, and found that there was a spell called "Blade Without a Shadow" written in the margin, and there were three small words "against the enemy" underneath.

And on the side, a second person wrote: "Extremely dangerous! It can easily cut off people's necks, and can only be used against enemies of life and death! ”

Harry and the four of them looked up at each other after reading it, it was the first time they had seen a second person comment on such a stern warning about a spell.

However, at this moment, Harry's "Die or Die" factor was activated, and he was eager to try this seemingly powerful spell.

Hermione was the first to sense that something was wrong with Harry, and she sternly said to Harry, "Harry, don't fight this spell, it's obviously a cult of black magic!" ”

"I don't want you to try it either!" Ginny said to Harry as well, "It's too dangerous. ”

Harry looked at Hermione and Ginny, then said......
