Drinking black tea calmly at Hogwarts

Harry Potter did not expect that what he said to the Black brothers and sisters in order to raise their vigilance would actually ignite the fighting spirit of the brothers and sisters.

As a child who grew up in the mountains, he and his fellow villagers caught bamboo rats in the mountains, fished in the river, helped with farm work, and occasionally followed candidates who were preparing to take the college entrance examination into the mountains to hunt wild boars. The brothers and sisters are very mobile. strong.

However, Alsace's first brainstorming plan was immediately rejected by Professor Rodney.Although no one smokes at Hogwarts, fireplaces and candles are still everywhere.If he really wanted to pour carbon monoxide into the pipes like Alsace thought, he might blow up Hogwarts first.

When Rodney returned home that night, he sent an e-mail to Zhang about this matter, which frightened Zhang. He didn't expect the two children to be so aggressive.

But Mr. Zhang quickly understood what the problem was. He was worried that the brother and sister would go into the secret passages that he filled with carbon monoxide to prevent the Death Eaters from invading, so he told them about the physical traps in the secret passages. The two of them, and it turns out that the two of them are now following suit.

The siblings were not going to be overwhelmed by such a small setback, and soon Jaina came up with a new approach.

The next Sunday morning, Neville routinely came to the greenhouse area to take care of the herbs inside.

When Neville walked to the greenhouse area, the corners of his mouth slightly curved, and he carefully observed the breached defense line around the greenhouse.

Neville was inspecting a vine that was limp on the ground. Under normal circumstances, if an animal touched the vine, it would immediately turn into a tentacle that he liked to see.He raised his head and looked not far ahead. There was a shallow shoe print on a small potato protruding from the soil. It was obvious that someone who walked past had cast a floating spell on himself.And the cacti next to the greenhouse that shoot out spikes when people approach are covered with dewdrops, just like the fat house happy water just taken out of the refrigerator, obviously they have just been frozen by people.

"It's a veteran," Neville thought. In the past two or three years, he hadn't encountered a student who could break through the first line of defense so cleanly.

So he cast a disillusionment spell on himself, and walked over to the greenhouse area.

The intruders obviously did not conceal their existence. Not only did they hang a sign saying "There are people inside" at the entrance of the greenhouse in accordance with relevant regulations, but they also wrote their names on the visitor registration book hanging by the door. "Extracurricular Investigations".

Walking into the greenhouse, Neville saw that Alsace and Jaina in white coats were each holding a small notebook, discussing something while writing and drawing in the notebook. Read the book to compare.

Neville listened behind them for a while, and found that they were recording the poisonous herbs in the greenhouse, such as which herbs produced poisonous smoke after burning, which herbs were harmless in contact with the skin but poisonous when eaten, and which herbs were the other way around. Category.

Then the siblings were taken back to the office by Neville.

In the office, Neville looked at the two brothers and sisters with a stern face. On the table were their notebooks, which recorded more than half of the poisonous plants in the greenhouse.

"Tell me what you two want to do"

Because a few years ago there were conflicts among classmates at Hogwarts, and some people stole poisonous herbs from the greenhouse to poison their enemies, so Neville had to pay attention to this matter.

If the two of them mixed several poisonous herbs to make a volatile compound poison, there might be a mass incident.

"Winter is coming, let's write down the location of the poisonous herbs first, so as not to make a mistake when it gets dark." Alsace's excuse is in line with Zhang's usual style.

Neville stared at Alsace and said, "Didn't someone tell you that non-toxic and harmless herbs are grown in special greenhouses, while poisonous and harmful herbs are grown in special greenhouses?"

Alsace was about to say "no", but he realized that Professor Longbottom had said this in the first herbal medicine class.

So Neville continued: "If you don't want to be tied to a chair and watch all the equipment and potions in your warehouse be disassembled or sold at the auction house at a low price, I advise you to tell the truth."

This trick was told to Neville by someone from Zhang, and Neville didn't know if it would work well, so he tried it first.

So Alsace resolutely gave up.

Alsace said, "Mr. Potter came to see us yesterday, and he told us about the snake."

Neville was stunned for a moment, and then secretly heaved a sigh of relief. He didn't want to attack the other students, but he didn't intend to let the two of them go.

"So you're going to find some poisonous herbs to protect yourself?" Neville asked.

The siblings nodded.

"Twenty points from Slytherin." Neville immediately deducted ten points from each of them, "No matter what your motives are, you have already violated the school rules prohibiting entering the poisonous herb greenhouse, so you will be punished. If you need Herbs in the greenhouse, you can submit the application report to me or the principal. Of course, I cannot guarantee whether it will be approved."

Finally, the siblings left Neville's office with a large stack of Herbology papers.

The two sat dejectedly on the grass by the lake, kept touching small stones on the ground, and then threw them into the lake.

"The poisoning plan failed." Sitting on the ground, Jaina held her bent legs with her left hand, her chin resting on her knees, and her right hand was touching small stones on the grass beside her.

Her plan was to make two kinds of rat poison that rats love, and take advantage of the opportunity that snakes eat in large quantities before hibernation, so that Nagini can eat the rats with the poison.The rats that took these two poisons separately were fine, but when the two kinds of poisons were combined in Nagini's body, they would produce severe toxicity.

However, this plan would not work now, because Neville strictly forbade the two of them from approaching the greenhouse area outside of school hours.

"puff"

Alsace threw a slightly larger stone into the lake, and at this time a silver-white woman's head emerged from the lake.

Goddess of No Water asks Arthas whether it was Frostmourne or Fire's Pleasure that you fell into the water, and Moaning Myrtle looks at him tearfully, "Why do you stone me"

The resentful look in Myrtle's eyes greatly condemned Alsace's conscience.

"I'm sorry, Myrtle." Alsace quickly apologized, "I didn't know you were underwater."

That's when Myrtle started howling, "Yeah, who'd have thought that Funny Myrtle would be in the water? Who'd have thought she'd be flushed down the toilet by Peeves, down the sewer to the bottom of the lake, They were stoned again."

Alsace stood at a loss on the shore watching Myrtle crying in the water, not knowing how to comfort her for a while.

After crying for a while, Myrtle dived into the water again.

At this moment, Jaina stood up and walked to Arthas' side.

"Did you hear anything from Myrtle's words just now?" Jaina asked.

Alsace nodded and said, "Tell me what you think."

"The castle's sewers are connected to this lake, we can make a fuss about it," Jaina said.

Then Alsace looked at his sister in horror, and asked, "You don't mean to block the outlet of the sewer, and then use the water from the toilet to drown Nagini?"

"Don't think of me so disgustingly." Jaina gave her brother a disgusted look.

At this time, Jaina squatted on the ground and drew a schematic diagram on the ground with her wand.

"Here is the complex piping system under the castle." Jaina pointed to a circle under the castle, and then she pointed from left to right and said, "This is the sewer leading to the bottom of the lake, and here is the lake water."

"We guess that Nagini spent most of his time living in a secret room under the castle, and the passage to the secret room is connected to the plumbing system."

"If we figured out a way to get sewers and other plumbing connections below the level of the lake, for example like this."

Jaina changed the schematic diagram on the ground, and then continued: "This way the lake can pour back into the secret room under the castle inside, and we can drown Nagini while she is hibernating."

"But we don't know the direction of the pipeline under the castle, and we can't get into the sewer, right?" Alsace said.

"We can ask Peeves for help," Jaina said.

At this time, the brothers and sisters didn't realize that a cat had already walked quietly behind them, and they had been listening to them discussing the plan to fill the secret room with water for a long time.

Two hours later, the loveless brother and sister left the principal's office with a stack of transfiguration homework.
