Harry Potter and the Old Ones

The real title of this chapter:

Research and preliminary exploration of the molecular mechanism of genetic growth and development of Animagus, three-dimensional animals and wizards

When the Christmas holiday was over, Tiera took the Hogwarts Express train. After five or six hours of long drive, Tiera stepped onto the platform of Hogsmeade Village again.

"Tiera!"

As soon as Tierra stepped out of the train, he heard someone calling his name in the distance——

Then Tierra crashed into a warm embrace.

"Long time no see, Tierra!" Harry said.

After Harry let go, Ron rushed up to hug Tiera again——

"Thank you! Thank you!" Ron said excitedly, "Thank you so much! Your gift is really great!"

"Li...a gift?"

Before Tiera could react, he saw a big black dog with smooth hair running over from behind Ron, circled Tiera in a circle, and then glanced mockingly.

Tierra: ...

Good boy, so you are waiting for me here.

I said that what I originally proposed was not to expose you to the Ministry of Magic, so why did you change it to not expose you to anyone.

"Where's Hermione?" Tierra asked, logically speaking, the deduction trio should always stick together.

Ron and Harry looked at each other—

"Well... Hermione has been a little busy lately..." Harry said.

"And she's kind of... kind of mad at you..." Ron went on.

"Angry?" Tierra asked, "Why?"

"Because... because you seem to have forgotten to give Hermione a Christmas present..." Ron said, "Hermione... Hermione doesn't seem to want to talk to you..."

"Oh... oh?" Tierra said, indicating that she knew——

And such a good thing?

If Tierra remembers correctly, Buckbeak's defense case should start after Christmas in the original book, which means that Hermione has to prepare a defense for Buckbeak while coping with double studies——

That is to say, it is difficult for Hermione to have the energy to pay attention to herself.

Regarding the matter of letting Sirius play herself, relying on the previous arrangement, Tierra is confident that she can hide it from others, but Tierra thinks that Hermione should be excluded from all of them—

It's hard to guarantee that Hermione won't notice anything abnormal after getting along day and night, which is why Tierra's deal with Black was terminated before the end of Christmas. The longer Black pretends to be Tierra, the more likely he will be exposed big.

When Tierra saw Hermione in the Gryffindor common room, Hermione did not attend the dinner celebrating the return that night, but sat in piles of files and flipped through the files, when Tierra appeared Afterwards, Hermione just raised her head, said "Hello" indifferently, and then continued to study the case of magical animal wounding with her head down.

Hermione didn't want to talk to her, and Tierra didn't want to make fun of herself. After replying politely, she returned to her dormitory.

Perhaps it was because of Sirius' unbridled love for his godson, Tierra clearly sensed that Harry's attitude towards her became more and more friendly——

This made Tierra somewhat uncomfortable.

"Harry...I'm a little tired today..." Tierra pretended to be very tired and said, "I really don't have the energy to discuss the Quidditch formation with you...Tomorrow, tomorrow, okay?"

"Oh...Okay, okay..." Harry said disappointedly, "Then you should rest first."

"Well, then I'll go to bed first, good night." Tierra said while yawning——

But that night, when everyone was quietly falling asleep, Tierra got up quietly, put on her clothes and shoes, and quietly came to the door of the bedroom——

Then a big black dog blocked the way.

Tierra: ...

The big black dog didn't roar, and just circled around Tierra.

Tierra: ...

Tierra had no choice but to give up her plan to go to the Chamber of Secrets openly, and had to change her itinerary and go up to the toilet in the Gryffindor dormitory. Sirius followed Tierra and also came to the toilet.

Tierra couldn't help it, after going to the bathroom with a fake appearance, she went back to the dormitory obediently, went to bed, and slept——

Sirius also followed behind Tierra step by step.

Apparently, Sirius had doubts about Tiera when he couldn't find Peter Pettigrew for a long time——

How did Peter Pettigrew disappear so coincidentally, just the night before he decided to break into Gryffindor Tower?

So after searching the entire Hogwarts castle last semester and failing to find Peter Pettigrew, Sirius changed his strategy——

Sirius Black prepares to keep an eye on Tierra.

After seeing Tierra lying on the bed again, Sirius paced up and down, and lay down at the door of the bedroom.

But what Sirius didn't notice was that during the few minutes when Tiera went to the toilet just now, the school uniform that was originally hanging by Tiera's window disappeared.

After Tierra lay back on the bed, her consciousness left her body and entered the "parasite".

At this time, the "parasite" has fallen to the women's bathroom on the second floor, and entered the secret room through the pipe that does not come out of the water.

As soon as Tierra flew into the secret room, she immediately heard chirping shouts——

In the center of the laboratory table in the secret room is a huge collection of sarcoid tumors. Looking carefully, the center of the sarcoma is exactly the face of Peter Pettigrew.

Around the sarcoma, there were thirteen huge bubbles suspended, and each bubble lived with a mother mouse and several suckling mice that were bigger than the mother mouse.

After the trip to the Dreamland, Tierra erased all Pettigrew Peter's memories about the Dreamland, and fabricated a false memory for him that he had been hiding in Tibet for the past few months.

Pettigrew's first wave of children was born in mid-November. Except for some deaths, Tierra harvested a total of fifty-seven Pettigrew Peter's second generation. This number is far lower than the normal reproduction number of the mouse generation. Among them, there were thirty-three male mice and twenty-four female mice.

The gestation period of a normal mouse is 19 to 21 days, but the gestation period of Pettigrew II lasted from August 13th to November 10th, a total of 89 days, nearly three months The time is about four times the normal mouse gestation period.

Moreover, the growth cycle of suckling mice is also longer than that of other mice. Normal mice are weaned three weeks after birth, enter puberty at five to eight weeks, and become sexually mature within forty-five to sixty days after birth. The second generation has not been weaned until now, and is still in the lactation period, and the size of the mice is much larger than that of normal suckling mice, but there are no specific human-like characteristics in structure.

Due to the longer growth cycle of Peter Pettigrew's second generation compared to other mice, Tierra's plan to carry out a large number of backcross breeding in a short period of time was completely defeated. The reproductive system of Peter Dwarf was separated separately, forming a separate life body dedicated to reproduction.

"Ah..." After observing the fifty-seven suckling mice in turn and accurately recording their shape and growth characteristics, Tierra sighed helplessly, "I have to do another experiment to study the effect of flesh and blood magic on biological reproduction. And whether there is any impact on the reproductive system."

"Although those illiterate people in the wizarding world don't care, I still can't get over this hurdle in my heart." Tierra said to herself—

This is a rigorous attitude towards experiments and truth as a scientific researcher.

Tierra knew in his heart that the results of his experiment were absolutely explosive, and it would not be an exaggeration to call it the originator of molecular biology, cell biology, genetics, and developmental biology in the wizarding world.

But if he dares to get it published in scince or nature, it will definitely be the result of being expelled from the scientific community and being arrested in prison——

Because Tierra's experiment has violated every knowledge point he has learned in the course "Engineering Ethics and Academic Ethics".

"To be honest, I really miss you." Tierra said, looking at Peter Pettigrew sadly.

"Fortunately, next year I can catch Rita Skeeter, her beetle Animagus has a shorter growth cycle than your mouse, hehehe."

The fifth more

The experiments involved in this chapter are all the products of the author’s mouth. Good children should not learn or think about it. At the same time, the author promises that the author is a person who has three views, loves the country, loves the party, and loves the people. He abides by laboratory operating specifications, animal experiment laws, and engineering ethics. Scientific researchers who adhere to academic ethics and writing standards will never be involved in any experiments that violate academic ethics and engineering ethics.

The behavior of the protagonist should not be promoted to the author.
