The Knicks didn't go back to Gryffindor with Harry and Ron, he was going to catch some mice. But looking at today's situation, no matter how many rats are released, they will be bitten to death and become new monsters. We need to find a way to make it give birth in peace.

At the end of the day, he had only harvested a few, and he wanted to wait too long before putting them in, thinking that he couldn't make a blood cocoon without enough flesh, and maybe he could stop the rats from doing something crazy.

Give it enough food, and if it is smart enough, it will reproduce on its own, and when it has more offspring, it will be bitten to death and used as flesh to make a blood cocoon. The separation he wants is possible.

You can't put too many mice at once, a few are just right.

Again at the Room of Requirement, the rats inside wilted and sitting by the food. Multiple scratches can be seen in the interior.

The Knicks saw a small hole in the wall. Walking to the pit, he found that the walls were two-tiered. The surface is damaged, the inner layer is smooth, I don't know if the rats can't dig it, or if the walls are repaired too quickly.

Several of the rats released were immediately bitten to death, but the rats did not immediately make blood cocoons after biting their own kind. It's waiting for the Knicks to leave.

Nicks added some more food and water, spelled out the dead rats on the ground, and left.

The next day he threw a few more mice, this time not being bitten to death immediately, and the Knicks didn't care, but left with the same water and food.

On the third day, Hermione came with the Knicks, and she had heard Harry and Ron talk about rats and wanted to see them.

The few rats that were put in were gone, replaced by a tiny blood cocoon.

"That's what they call a blood cocoon?"

"That's right, Dumbledore is interested, can you go and help me inform him?" The Knicks see the rat standing by the blood cocoon.

A few minutes later, Dumbledore arrived, and when he entered, the rat immediately detonated the blood cocoon. The blood in the sky turned into a blood-colored ice spear and shot at Dumbledore.

Dumbledore just waved his wand and the ice gun was stopped.

"It was a real surprise." Dumbledore spoke with regret.

The Knicks cleaned up the trail and dropped a few rats to leave with Dumbledore.

On the fourth day, Nicks went in again to find that the rats he had put in had not died, and that there were a few more cubs, and it turned out that one of the rats he had put in yesterday had given birth. He didn't kill the rats, he added water and food and left.

Over the next few days, there were more and more rats.

The day before school started, the Knicks came to the Room of Requirement, and there were already a lot of rats, scurrying around, eating up all the water and food that Knicks had left behind.

Nicks thought about it, and configured a hunter sequence 7 arsonist potion on the spot, grabbed the rats on the ground and fed them.

The rat broke free from its grip and tried to run back to the pack, but after a few steps, it died.

The potion was also not absorbed, killing the rats like poison, and it didn't even have time to distort.

Nicks used a spell to restore the potion, grabbed the other one and continued to feed it, and after consuming most of the mice, one of them finally absorbed the potion, but this rat didn't survive and was distorted.

Its head and tail are connected together to form a circle, and the flesh and blood of the whole body are rolled up, and the internal organs disappear, forming a circle of flesh with limbs, and flames are condensed in the circle, spraying everywhere.

There is not much flesh and blood of a mouse, and the flesh circle formed is naturally not large, and there is not much magic power, so it stops after spraying for a while.

The Knicks took the opportunity to dispose of it and get a piece of wreckage. Looking at the wreckage in his hand, he felt melancholy, and there were not many people in the school who were capable of dealing with it. The best candidate was Dumbledore, but he had an inexplicable feeling about Dumbledore.

Every time I approached Dumbledore, I couldn't tell whether I was happy or afraid, a feeling that it was a good thing to get closer to the other person, but also that I couldn't get too close to him, otherwise something would definitely happen.

Carefully place the remains, clean up the dead rats, add water and food, and leave the Room of Need. He didn't notice the original mouse's gaze flickering.

Back at Gryffindor, Seamus and Neville surround him.

"Knicks, we've heard. You've got a magical rat that's better than Ron's Spotted. ”

Nicks was stunned, and after the two of them finished talking, he realized that Ron had told Knicks about experimenting with mice, and the whole Gryffindor knew.

Seamus excitedly said, "The Knicks will take us to have a look, rest assured, I won't sabotage your experiment." ”

"Can I say no?" Nick Dow.

"Of course not, let's see."

"Actually, now it's gone, and it's no different from a normal mouse." The Knicks tried to dispel their curiosity.

"Take us to see it, if there is no special place, we are so dead." Seamus Road.

"Well, you're going to be disappointed."

The Knicks are back with the people back to the Room of Requirement.

When he opened the door, he was stunned.

The house was littered with dead rats, and a blood cocoon grew rapidly in the middle of the room.

Everyone exclaimed at the sight of the blood cocoon, and some people turned around and ran to inform their friends.

When the rat saw everyone, he was afraid that the Knicks would clean up the flesh and blood, and immediately accelerated the growth of the blood cocoon.

Nicks turned and grabbed Hermione and said, "Go find Dumbledore, the blood cocoon he asked for has reappeared." ”

Hermione turned to leave.

Soon there were a lot of students gathered at the door, and they all heard the letter to come and see the excitement.

Dumbledore and Hermione were stopped outside, but he was not angry, and said to Hermione, "Miss Hermione Granger, can you give me one of your hairs?" ”

Hermione plucked one at random.

Dumbledore opened a medicine bottle and said, "Put it inside." ”

"Polyjuice potion?!" Hermione recognized the potion, and out of trust in Dumbledore, she put her head inside.

Dumbledore drank the Polyjuice Potion, and his whole body shrunk and turned into Hermione, but the wide clothes on his body made him look very funny.

Hermione smiled unkindly.

Dumbledore put the bottle of the compound potion in Hermione's hand, waved his wand, turned the clothes on his body into Hermione's school uniform, and squeezed into the crowd with great effort.

When he came to the Knicks, the Knots asked, "Hermione, where's the Headmaster?" ”

Dumbledore pulled out a box and explained, "He told me to put things in the box. ”

The Blood Cocoon has absorbed the flesh of all the dead rats, becoming as tall as the Nix.

Dumbledore waved his wand against Hermione's face.

The rats in the field were suppressed, and the blood cocoons quickly flew into the small box. The small box was isolated from the outside world, and the blood cocoon was not controlled by the rat after entering, and did not explode.

Ron beside him exclaimed, "Hermione, what are you doing, it's dangerous, you should go to Headmaster Dumbledore." ”

Nick looked at the wand in Hermione's hand thoughtfully, the small box didn't look like Hermione could take out, and he had a guess in his heart.
