The meal was very embarrassing due to Hagrid's mistake revealing the secret of the Philosopher's Stone.

Before seven o'clock in the evening, Luo Xiu got up to say goodbye and left, but Hagrid did not stay, and personally sent Luo Xiu out.

And after Luo Xiu left, Hermione unabashedly expressed her suspicions about Luo Xiu.

"Hagrid, you've revealed the location of the Philosopher's Stone, and that's broken! Luo Xiu has always been thinking about the Philosopher's Stone, and he will definitely steal the Philosopher's Stone! ”

Hagrid hurriedly shook his head: "No, Hermione, don't think nonsense, how could Luo Xiu steal the Philosopher's Stone?" That's impossible. ”

"How could it be, I clearly heard him and Snape talking about stealing the Philosopher's Stone, these two snakes and rats are not a good thing!" Hermione whispered.

"Hermione, calm down, your worries are unnecessary, neither of them will do anything harmful to Hogwarts." Hagrid said in a deep voice, and then quickly changed the subject, "Okay, it's time to give you Christmas presents, you can guess what kind of gift I gave you......

Hermione couldn't continue the conversation and sighed helplessly, exchanging glances with the two friends, and finding that Harry and Ron seemed to share her concerns.

Leaving Hagrid's hut, Luo Xiu went straight back to the library, where he had more important tasks to complete.

The last time he performed alchemy, Luo Xiu accidentally discovered the intermediate substance of matter transformation - this is a very wonderful substance, it has rich and variable properties, as long as it is changed through consciousness, it will become any kind of matter desired.

What Luo Xiu needs to do now is to keep this substance as much as possible, not as fleeting as a flash in the pan, once this substance is obtained, Luo Xiu's research on alchemy will have a breakthrough.

Sitting in a hidden corner of the library, Luo Xiu took out his magic amplifier, and he waved his wand and aimed it at an iron block on the table.

The purity of the iron block is very high, and although the surface layer has been heavily oxidized, it is much less difficult to transform the iron block than a piece of wood.

The gold spell was cast, and a flash of light from the wand hit the iron, and soon the iron changed, shaking violently on the table.

With the transmission of magic power, the microstructure of matter changes, and this time Luo Xiu attempts to turn iron directly into gold, but his real purpose is to obtain the intermediate product of material transformation.

At that moment, Luo Xiu even felt the vibration of protons and neutrons at the microscopic level, and the massive conversion between particles would have produced a huge amount of energy, but alchemy cleverly skipped this process and rewrote the transformation of matter and energy into a direct change between matter.

In an instant, Luo Xiu keenly captured the change of the iron block, and the iron began to collapse rapidly in the same direction, forming a new mercury-like substance, although Luo Xiu could not see the composition of this substance from the microscopic level, but he could clearly feel its existence.

"Stop!"

At this moment, Luo Xiu reacted immediately, and he almost used all his strength to stop his alchemy, trying to maintain the form of this new substance.

But he failed.

This new substance exists no more than hundredths of a second, and it is too difficult to make an instantaneous reaction in this hundredth of a second.

By the time alchemy was terminated, three-quarters of the iron had been turned into gold, and the other quarter had been reduced to iron, leaving the new substance behind.

"Maybe it's not a substance, but an intermediate state...... Luo Xiu pondered in his heart.

Just then, Mrs. Pince, the librarian, approached impatiently.

"Slytherin boy, you'd better be quiet! It's Christmas, but you have to behave! ”

Mrs. Pince said with a gloomy face, as if Luo Xiu owed her a large sum of money.

In fact, Luo Xiu was already lucky, if the others dared to make such a big noise in the library, then Madame Pince would have blasted them out with her magical feather duster.

Rothew was accustomed to Mrs. Pince's vicious attitude, and instead of being angry, he smiled and said, "Good Mrs. Pince, I wish you a Merry Christmas. ”

"Humph! Don't think I'm going to eat this! Mrs. Pince said with a cold expression.

And at this moment, Luo Xiu said something that made Mrs. Pince gasp.

"Merry Christmas to Professor Snape, please, please help me relay that."

When she heard the word "Snape", Mrs. Pince's expression changed significantly, and she was silent for a long time before she stammered and asked, "Bless Snape, what are you talking to me for?" I can't convey it to you! ”

"Oh? Really? Mrs. Prince...... Oh no, Mrs. Pince. Luo Xiu said with a smile.

After saying this, Mrs. Pince's face turned completely pale, she stared at Luo Xiu, and asked in disbelief, "What do you know?" ”

In fact, this is a small secret in the Harry Potter universe, and Rosho once peeked into this secret when he was a spectator of this universe.

Mrs. Pins, the librarian, had the same black hair and hooked nose as Professor Snape, and even had the same temper, which was not accidental, but a hint at their secret relationship.

Professor Snape's mother is known to be a pure-blood wizard from the Prince family, who is proud of his pure-blood wizard lineage and refers to himself as the "Half Prince" (often misunderstood as the half-blood prince).

The full name of Mrs. Pince, the librarian, is Irma Pince. Pince), a name that, if rearranged alphabetically, becomes a phrase – "I'm a Prince."

From these details, it is not difficult to guess that the librarian, Mrs. Pins, is actually Professor Snape's mother, Mrs. Prince, who has wizarding blood.

Now, based on Mrs. Pince's reaction, Rosho could basically conclude that his speculation was correct, and that Professor Snape was her son.

"I know many things, Mrs. Pince, I know that Professor Snape is a kind and loyal man, and I know that you are a kind mother. I won't disturb the lives of your mother and son, and please don't disturb my studies, okay? Luo Xiu said with a smile.

Mrs. Pince's face changed, and Luo Xiu's words were tantamount to coercion in disguise.

But her biggest secret was known by Luo Xiu, which had already made her situation passive, even if she was reluctant in her heart, she could only compromise.

"Boy, I won't disturb your studies, but please don't give away the secrets you know." Mrs. Pince whispered, her attitude now much more humble.

"Don't worry, Mrs. Pince, I'm a man of promise." Luo Xiu was satisfied with Mrs. Pince's attitude and said with a smile.

Mrs. Pince nodded, then turned to leave.

And Rothew knew that from now on Mrs. Pins would never come to scold him loudly.
