Over the next few days, Jon Hart thought about the plan.
How to remove a hair from Snape, or a piece of tissue from his body?
But he rejected all the plans one by one because the risks were too great...
Snape is an extremely good potion master, and his understanding of "Polyjuice Potion" may be deeper than he imagined.
Want to steal a part of his body?
Strictly speaking, it was not impossible... but if I showed any sign of weakness, he would probably find out and guess the existence of the Polyjuice Potion; and given the relationship between Snape and Dumbledore, I might have to go to Dumbledore's office to "have a talk" in an hour.
All the plans that came to mind were quickly rejected by Jon.
But there is still a solution!
...
...
After much thought, Jon found another feasible method...but it was a little troublesome.
But that is the safest method.
He took out a pen and paper and wrote a letter.
The letter was addressed to Mr. Robert Wilson, owner of a hardware store at 21 Winchester Road, Southampton; Jon asked Mr. Wilson to help him buy some things on behalf of Urian Wrynn.
And send it to Mr. Hart, Hufflepuff House, Hogwarts School.
…
About a week later, Owl appeared in the dining hall every now and then, carrying large boxes, and then threw the boxes to Jon.
"Who sent you so many things?" Zacharias asked curiously.
"Just some gadgets used by people who can't do magic..." Jon said vaguely, "One of my relatives sent it to me!"
However, every time he received an email, Jon would find an opportunity to rush to the Room of Requirement on the eighth floor of the castle to install those things.
At the same time waiting for the opportunity to get close to Snape.
…
In a Potions class at the end of January 1993.
Snape spent the entire afternoon teaching them how to prepare a potion called "Sleeping Potion".
Jon and Astoria were the first in the class to complete the preparation, and Snape was the last to evaluate them as usual... In order to prevent the potion from evaporating, he deliberately covered the crucible with the lid.
As usual, Snape criticized almost every student in the class.
When the get out of class was about to end, he turned his attention to Jon and Astoria in the first row.
Taking a big step forward, he stretched out his hand and opened the crucible.
Looking at the clear blue liquid in the crucible, he just nodded slightly.
In more than half a semester of Potions class, Jon and Astoria had hardly ever failed, and he had gotten used to it.
Without saying anything, Snape prepared to put the lid back on the cauldron...
"Professor, let me do it!" Jon said quickly, extending his hand.
At this moment, the scraper in his hand accidentally scraped the back of Snape's hand.
"I'm so sorry, Professor..." Jon stood up in panic.
Snape withdrew his hand with a cold expression. The touch was very light, so there was no bleeding, only a faint white mark.
"Sit down!" Snape glanced at him coldly and ordered, "Mr. Hart, didn't I tell you that after preparing any potion, the knife must be put away?"
"I'm so sorry... I just forgot..." Jon quickly sat down and explained.
"Five points from Hufflepuff!"
"Now, get out, class is over..."
…
"What on earth were you thinking just now... It's unbelievable that Professor Snape only deducted five points... I thought you were going to be put in detention..." As soon as Snape left the classroom, Astoria hurried over and said with a serious look on her face.
"Sorry, I was distracted just now." Jon smiled bitterly and carefully put the scraper into a crystal bottle filled with red liquid.
"Let's go to the dining hall together?" Astoria asked in a low voice after looking around.
"No, I have something else to do!" Jon packed his things hurriedly and rushed to the eighth floor of the castle.
…
On the eighth floor of Hogwarts Castle, opposite the tapestry of the troll beating up Barnabas with a club.
"I need an ice room... I need an ice room..." Jon, who had already walked to the Room of Requirement, said silently in his heart.
He walked past that section of wall three times, and when the brass handle appeared on the wall, he quickly pushed the door open.
The Room of Requirement was now filled with ice. Jon then ran to the left, removed a large block of ice, and took out the bottles and jars hidden in it:
DMEM cell culture medium;
Gibco fetal bovine serum;
PBS buffer;
Kanamycin;
Ampicillin...
These were the reagents that Jon had ordered from Mr. Wilson.
Jon took out bottle after bottle of biological reagents, and he also took away a box of ice cubes.
Since it was too risky and difficult to blatantly remove a part of Snape's body, he could only resort to his old tricks... to cultivate Snape's cells into tissues through laboratory methods.
As these reagents were taken out one by one, the entire Room of Requirement began to undergo earth-shaking changes!
The ice disappeared little by little, and then the Room of Requirement turned into a greenhouse maintained at around 37 degrees... this is the most suitable temperature for cell growth.
There were also some instruments in the cabin, which were ordered by Jon a few days ago and secretly brought over.
Including microscopes, centrifuges, incubators... After several days of hard work by Jon, this place has become a simple microbiology laboratory.
There is also a small diesel generator.
Jon carefully took out the epithelial cells of Snape that he had collected before, which were secretly scraped from Snape's hand with a scraper.
As soon as he collected it, he placed it in the culture medium.
The culture medium was carefully centrifuged at 800 g and the supernatant was discarded; then the culture medium and serum were re-added to the cells.
Because there was no way to ensure sterility, Jon had to add one thousandth of antibiotics to the culture medium.
After a period of simple processing...
Finally, Jon carefully placed the bottle of cells in the incubator.
After leaving the Room of Requirement, he just hoped that everything would go well!
...
...
...
The experiment of cultivating Snape cells is progressing quite smoothly!
The vitality of wizard cells seems to be much more vigorous than that of ordinary mammal cells.
Before, Jon was still worried that he had only sampled a small amount and that the cells might not grow in the cell bottle, or that it might take more time; it turned out that he was worrying too much... After only a dozen hours, Snape's cells had completely filled the cell bottle.
Next, Jon carefully digested and passaged the cells...
For the next week, Jon came to check on the cells every day.
Due to limited conditions, he was unable to clone a small piece of Snape's epithelial tissue in such a simple environment... He could only allow these epithelial cells to multiply in large quantities and continue to culture them after passaging.
Of course, he still tried to get back to the Hufflepuff common room before dark every day.
Although we already know that the basilisk will not appear again for some time, it is still necessary to be prepared.
The previously very small number of cells had grown to fill more than a dozen cell bottles after a week of culture.
...
...
…
On the second Friday afternoon in February, Jon felt that the number of cells was enough.
He carefully collected more than ten bottles of cells, digested and centrifuged them, and collected them together; of course, he also left two bottles of cells for further cultivation in case of emergency.
Looking at the white "meat foam" the size of a little finger stacked together... although it is a bit ugly, it was indeed once a part of Snape's body!
Hopefully this works!
When everything was ready, Jon took out some of the "minced meat" and added it to a cup of polyjuice potion that had been prepared long ago.
The cup hissed and bubbled rapidly...and after only a minute, its color changed to a deep red.
Looking at the cup of crimson Polyjuice Potion, Jon's originally uneasy heart calmed down a little.
Pinching his nose, he drank the entire cup of potion in one gulp... It tasted pretty good, a little bitter, but not as disgusting as he had imagined.
It felt the same as before...my internal organs quickly began to churn, as if I had just swallowed a few live snakes!
Jon bent down and quickly and expertly changed into a large robe.
Then, a burning sensation quickly spread from his stomach to his whole body. He felt his body melting again, as if the skin all over his body was bubbling like hot wax... He lay on the ground, watching his hands begin to grow bigger, his fingers become thicker, his nails become wider, and his shoulders begin to extend!
A minute later, he stood up...
A thin body, greasy and straight hair, sallow skin, a big hooked nose... and an extremely cold look in his eyes.
Severus Snape appeared in the Room of Requirement.
He succeeded!
…
Jon suppressed his excitement as best he could.
Not many cells had been cultured before, and they could not maintain their deformation for too long, so he had to hurry.
Snape's body was much weaker than that of the Russian special forces soldier, and could be said to be a little sickly... But for a wizard of his level, this was not important at all.
Jon sat down quickly, closed his eyes... and began to feel the intuition that Snape had when he closed his mind.
"Concentrate your mind and block your brain..."
"Restrain your thoughts..."
"Don't think, don't remember, don't feel..."
Ten minutes later, Jon opened his eyes again.
As he had expected, this method was very effective...understanding Snape's intuition and the way Snape closed his mind; it only took ten minutes, which was almost more efficient than the three months of hard practice before.
Jon quickly closed his eyes again and continued to comprehend.
The human heart is not a book that can't be flipped through at will; thoughts are not engraved in the skull and can't be read by others... Legilimency is not simply reading memories, but to understand the contradictions and feelings in the other person's memory and make the correct interpretation...
Brain closure must be the opposite of this, sealing off the feelings and memories of the shield of lies, so that the other party cannot make a correct judgment on your thoughts. At the same time, hide the real memory in the deepest place, and protect it with falsehood, so that even the most powerful wizard cannot discover your truth.
…
An hour later, Jon Hart's slightly thin body reappeared in the Room of Requirement.
He gasped for air to relieve the pain caused by the polyjuice decoction's transformation... But he could feel that his brain had never been stronger than it was now! He was almost within reach of completely mastering the brain block technique.
First I had to take a break. Luckily I went to the kitchen and got a lot of chocolate a few days ago.
Jon first ate a large piece of chocolate to restore some of his strength.
Then, he quickly took out the Polyjuice Potion that had been prepared long ago and hidden in the Room of Requirement, and added Snape's cells again... This time, he took double the amount!
Transforming into Snape once again, Jon continued his practice.
…
A few hours later, Jon's face turned a little pale.
But it must be said that the effect is very obvious... He once asked the Room of Requirement to create countless noises in the cabin, but when he was in it, he was not affected by these noises at all and did not feel uneasy.
Although he is currently unable to completely block his brain from intrusion, he can proactively store all of his "shameful" memories in the deepest part of his brain in the form of false memories, making them undiscoverable!
…
Jon ate a few more pieces of chocolate to regain some strength, then stood up and prepared to return to the Hufflepuff common room.
But at this time, he found some trouble.
Before he knew it, he had been in the Room of Requirement for more than six hours... It was already past nine o'clock in the afternoon, Greenwich time, and it was completely dark.
There was already a curfew in Hogwarts Castle.
Jon pursed his lips, seeming to be in some trouble.
Although the basilisk is unlikely to appear in the school during this period, we still have to be prepared for the possibility; and apart from anything else, even then getting caught by Filch, the impact will not be good!
After all, wandering around the school at night is against school rules.
Jon thought carefully for a moment and took out a small bottle of khaki-colored Polyjuice Potion.
Soon, Soviet agent Sergei Pavlov appeared in front of the Room of Requirement.
With Pavlov's skills, even if he met Filch, he should be able to get rid of him easily... After all, Mr. Filch is just a squib.
He took enough to transform for ten minutes, which was enough for him to walk from the eighth floor to the Hufflepuff common room.
Pavlov put on a large black wizard robe, covered his face with a cloak, walked out of the Room of Requirement, and disappeared into the lights of the night.
