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 holidays ended, Tiera took the Hogwarts Express, and after a five- or six-hour long drive, Tiera set foot on the platform of Hogsmeade Village again.

"Tiera!"

As soon as Tiera got out of the train, she heard someone calling his name in the distance——

Immediately afterwards, Tiera slammed into a warm embrace.

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

After Harry let go, Ron rushed up and hugged Tiera again—

"Thank you! Thank you!" Ron said excitedly. "Thank you so much! That gift of yours is amazing!"

"Gift...gift?"

Before Tiera could react, he saw a **** dog with smooth hair running from behind Ron, circled Tiera, and 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?" Tiera asked, and it stands to reason that this trio of deductions should always stick together.

Ron and Harry looked at each other -

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

"And she's a little...a little bit mad at you..." Ron continued.

"Angry?" Tiera asked. "Why?"

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

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

And such good things?

If Tiera remembers correctly, in the original book, after Christmas, Buckbeak's defense case should begin, which means that Hermione has to prepare a defense statement 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.

The matter of letting Sirius play the role of herself, relying on the previous arrangement, Tiera is confident that she can hide from others, but among all of them, Tiera feels that Hermione should be excluded——

It's hard to guarantee that Hermione won't find anything unusual when they get along day and night, which is why Tiera's initial deal with Blake ends before the end of Christmas. The longer Blake pretends to be Tiera, the more likely he will be exposed. big.

When Tiera saw Hermione in the Gryffindor common room, Hermione did not attend the dinner celebrating the return that night, but sat in the piles of files and read the files. When Tiera appeared After that, Hermione just raised her head, said "hello" indifferently, and then continued to lower her head to study the case of magical animals hurting people.

Hermione didn't want to take care of her, and Tiera wouldn't make fun of herself. After a polite reply, she returned to her bedroom.

Perhaps because of Sirius' unrestrained love for his godson, Tiera clearly sensed that Harry's attitude towards her was becoming more and more affectionate——

This made Tiera somewhat uncomfortable.

"Harry... I'm a little tired today..." Tiera pretended to be tired and said, "I really don't have the energy to discuss Quidditch formations with you... Tomorrow, how about tomorrow?"

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

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

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

Then he was blocked by a **** dog.

Tierra:  …

The **** dog didn't growl, and just circled around Tiera.

Tierra:  …

Tiera had no choice but to give up her plan to go to the secret room openly, and had to change her schedule and go up to the toilet in Gryffindor's bedroom. Sirius followed behind Tiera and went to the toilet as well.

Tiera couldn't help it. After going to the toilet in a fake manner, she returned to the bedroom, went to bed, and went to sleep—

Sirius also followed behind Tiera.

Apparently, Sirius had doubts about Tiera after seeing Peter Pettigrew for a long time——

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

So after visiting the entire Hogwarts Castle last semester and not finding Peter Pettigrew, Sirius changed his strategy——

Sirius Black was ready to keep an eye on Tiera.

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

But what Sirius didn't notice was that just a few minutes after Tiera went to the toilet, the school uniform that had been hanging by Tiera's window disappeared.

After Tiera 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 contain water.

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

In the center of the laboratory table in the secret room was a huge collection of sarcoma. When the self-study looked at it, the center of the sarcoma was the face of Peter Pettigrew.

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

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

The first wave of Pettigrew children was born in mid-November. Apart from some deaths, Tiera harvested a total of fifty-seven Pettigrew Peter II children, which is far lower than the normal reproduction number of the mouse generation. Among them, there were 33 male mice and 24 female mice.

The gestation period of normal mice is 19 to 21 days, but the gestation period of the second generation of small dwarfs lasted from August 13 to November 10, a total of 89 days, nearly three months. time, about four times the gestation period of normal mice.

Moreover, the growth cycle of suckling mice is also longer than other mice. Normal mice are weaned at three weeks after birth, enter puberty at five to eight weeks, and sexually mature forty-five to sixty after birth, but fifty-seven pettiga 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 is no special humanoid structure in structure.

Due to the longer growth cycle of Pettigrew Peter II compared to other mice, Tiera's plan to carry out a large number of backcross breeding in a short period of time was completely unsuccessful. In desperation, Tiera had to use flesh and blood magic, Dwarf Peter's reproductive system was isolated to form a separate organism specialized in reproduction.

"Alas..." After observing and playing with fifty-seven suckling mice in turn and accurately recording their mentality and growth characteristics~lightnovelpub.net~ Tiera sighed helplessly, "I have to do another experiment later. Research whether flesh and blood magic has an effect on biological reproduction and reproductive systems."

"Although the illiterates in the wizarding world don't care, I still can't get over this hurdle in my heart." Tiera said to herself.

Tierra knew in his heart that the results of his experiment would be absolutely explosive, and it would be no exaggeration to call him the originator of molecular biology, cell biology, genetics, and developmental biology in the wizarding world.

But if he dared to get it published in since or in nature, it would definitely be the result of being removed from the scientific community and being thrown into prison——

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

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

"It's good to catch Rita Skita next year. Her beetle Animagus has a shorter reproductive cycle than your mouse, hehe."
