Felix knocked on the basement door, and Snape was wearing a black top that had not changed for thousands of years, with curly black hair on his back, and his motionless black eyes always reminded Felix of the grilled fish he ate in the cold wind in the courtyard that day.

The doorman silently moved out of the position, revealing Professor Bubaji who was lying on the table. Her hair was messy, like a pile of straw, and her wide glasses were pitchforks stuck in the hay. Professor Bubaji was carefully looking at a flower pot.

"Did I miss something?" Felix asked happily.

"You're here just in time, Felix." Professor Bubaji said excitedly, his face still not moving away from the pot. "I told Severus that I must wait for you to come and witness this scene..."

"There's nothing to witness," said Snape.

He slammed the door, strode to the table, and took out a glass bottle from his shirt pocket. "Have you good luck," he said coldly, Professor Bubaji hurriedly moved away, holding his breath and watching Snape carefully unplug the cork and drip a drop of liquid into the pot.

A magical scene happened.

A small bag of brown soil in the flower pot bulged, revealing a faint touch of tender green. Under the silent gaze of the three, a few minutes later, a green bud as big as a palm swayed gently in the flower pot.

"This is..." Felix asked.

"Rejuvenation potion, a magic potion that promotes the germination of plants," said Snape.

"Don't you need to add a regeneration potion? I remember that these two potions can help most of the wilted plants recover health." Felix asked curiously.

“There is no need to waste,” Snape said, “the seeds provided by Bubaji are sufficiently nutritious.”

"Can I take it back?" Professor Bubaji begged, and she stared at the seedlings in the pot.

"Oh, no," Felix said immediately, "we promised."

He wanted to take this pot of plants for testing, mainly to see the changes in the nutrients in the soil and the subsequent growth of the plants. Bubaji also knew this, but he was reluctant to let it go. At the moment, she looked at Snape pitifully again, "Severus..."

"I only make this bottle of potion." Snape snorted, "use the simplest ingredients as required by someone."

Felix comforted Professor Bubaji and said, "There is no need to worry, Keridi, it is time to go. From the germination, growth, flowering, and fruiting of the seeds... We only need to understand the first step for the time being. Compared with the normal growth cycle, it can be at least half a month faster?" He asked Professor Bubaji.

"Yes, absolutely," she said confidently.

"That's enough," Felix said. "Don't think it's inconspicuous. It's amazing to study this process thoroughly. It's worthy of a Merlin Medal..."

Professor Bubaji left with a blush on his face. She now wanted to apply for a piece of land to build an experimental greenhouse from President Dumbledore.

"Sprout will definitely help, and she will be happy." Snape said dryly at the door, hoping that she would not bother herself in the future. He turned his head and found that the culprit was sitting leisurely on the sofa and flipping through magazines.

"What did you think of again, a new 'trump card'?" he said sarcastically.

"I'm wondering if the Avadasauri can kill bacteria in the water... Well, I'm kidding, forget it." Felix hurriedly said when he saw the expression on Snape's face. "I've got something to tell you that Mr. Scarmand has found a way to make the snails stable. He said in the letter that the larvae of the snails are flooded now, and I'm asking if I need it..."

Snape thought seriously for a while.

"The mucus of the larvae of the snail is corrosive, but it is well handled and can remove the characteristics of specific potion materials, making it an excellent auxiliary ingredient."

"Then you'd better publish a few articles and help promote it," said Felix.

Snape nodded, which was what he hoped. The office was quiet, and Snape stared at the specimen jar on the shelf against the wall and said, "I'm told me that you have the crown of Ravenclaw in your hand..."

"Dumbledore said?" Felix asked.

"It's not him," Snape said.

Felix frowned. Only Dumbledore knew about this. He had never taken it out and displayed it himself. He felt too shameful and had been secretly using it. However, Valen wore it for a while when he first studied, but Valen didn't know what it was. Apart from that

"Is it the Ministry of Magic who told you?" Felix said while thinking, "but even if there are not many people in the Ministry of Magic who know about this, such important filing documents will generally not be taken seriously unless someone deliberately looks for them... Oh, I understand."

Voldemort still reached into the Ministry of Magic.

"What is that?" Snape said softly, and he had been asking. "It is impossible to be a mere relic of Royna Ravenclaw. Although her crown is said to increase human wisdom, the Dark King attaches much importance to the crown more than the legend itself."

Felix fell into silence. The fewer people knew the secret of the Horcrux, the better. But since Sirius knew it... he seemed hesitant, and his biggest worry was that Severus himself deduced that Harry was the secret of half-horoscope. In fact, Sirius was also a hidden danger, but Sirius didn't know much about Horcrux, especially he didn't know that he could use living creatures to make Horcrux, and Severus had the chance to know the existence of the snake.

"It has to do with his immortality?" Snape asked in a low voice.

He carefully observed the expression on Felix's face, and although he found nothing, a moment of silence was enough to make him guess part of the truth.

Snape did not ask any more questions, but instead changed the topic and said: "The Dark King found this news through a spy from the Ministry of Magic. He asked me to indirectly attack, but I think it would be better to ask you directly. I have enough trouble and don't want to waste time..."

Felix smiled, "This is indeed the most time-saving way. Maybe Voldemort will praise you for being efficient."

"I don't plan to report it right away," said Snape. "The Dark King attached great importance to this matter, even surpassing his desire for the thing in the Ministry of Magic's Mysterious Affairs Division. He revealed to me that he would find opportunities to arrange for spies to cooperate with me."

"Come to school?" Felix found it funny.

The plan is good, but with Snape there, it seems a bit ridiculous. He didn't pay much attention to it. If he arrested the spy now, it would probably reveal Snape's undercover identity. Felix speculated that Dumbledore might be able to go with the flow and wait for the spy to fall into the trap. Then it will see who will come to school.

He was inexplicably expecting it.

Voldemort now has only one Horcrux with him, and he probably has reached the extreme insecurity. He just doesn’t know whether the gold cup is on him or Bellatrix Lesterlanch. From various perspectives, Voldemort is not the only person who entrusts his wealth and life to his subordinates. So...

Felix tried to simulate Voldemort's thoughts at this moment: What would I do if I were him in Voldemort's situation?

First, we must confirm the safety of the Horcrux.

‘I’m sure there are three destroyed Horcruxes, diary, snake, and ring; Horcruxes that cannot be determined include crowns and lockets. The crowns may be in school, um, ‘I’ do not know yet on Felix Happ. And lockets “Where are you going to spend the Christmas holiday, Severus?” Felix raised his head and asked. Snape looked at him in surprise and replied reluctantly for a while: “Go to the Order of the Phoenix to do something…” Felix retracted his gaze, very well, and understood, so ‘I’ suspected that the locket was stolen by his former servant. Regulus died more than ten years ago. If the Horcrux was not destroyed, the biggest possibility was in the old Black house where he could not enter.

What else?

‘I’ also know that I have some connection with Harry Potter in school. I have to use brain closure surgery to protect my brain in the past two months... Although I’m frustrated, this is the best way now... because ‘I’ is not sure whether this connection will extend to other Horcruxes. Damn, I only say half of the prediction! Damn Harry Potter! Now ‘I’ must ensure that the only Horcrux is under my nose and must not be separated from the Golden Cup, unless there is a last resort...

Felix thought hard, and he was going to find this reason now. He continued to think:

There are two people in the wizarding world who are on the same level as him. If they hit the trap, they will never be restored. Therefore, "I" must be careful enough, but "I" knows that one of them is not long, and I just need to wait with peace of mind... But if necessary, I don't mind sending him a ride when he is weakest. That feeling must be wonderful. The premise is that he holds the Horcrux that is crucial to "I" in his hand...

Felix suddenly realized.

Is this Dumbledore's plan? Use Horcrux to fish for Voldemort? But this battle seems to have no place for itself, it is a one-on-one situation between Dumbledore and Voldemort...

"What can I do?" Felix asked himself, "Yeah, it's so simple, I should have known it long ago." He said happily.

Of course, I took the opportunity to get the last Horcrux.

This is the reason why Voldemort and the Golden Cup Horcrux had to separate. No one would be stupid enough to take his other life to participate in the life-and-death duel. Even if there was a sick person on the other side, the only person Voldemort could entrust was Bellatrix Lestrange.

Snape stared at Felix, who was muttering to himself, knowing nothing about his complex psychological activities.

"Do you want to play a game of crackling cards, Severus?" asked Felix in a good mood.

...

Of course, the cards were not played.

Felix came out of the Potions Office, and there was a list of student clubs posted on the notice board in the foyer, but that was already three weeks ago.

Christmas is coming soon.

Felix plans to go to Newt's house during the holidays to update his "material library". At the same time, he is also preparing to go around the world and take the opportunity to collect some rare magical animals. When passing through a huge armor in the corridor, he suddenly stops and looks carefully. It seems that there is some magic hidden inside...

The armored helmet also lowered his head slowly and looked at Felix.

Felix: "…"

"Bang, bang, bang..."

"Hosh, hush, hush..."

Felix stopped beating his armor, turned his head to look at the light-colored raging eyes of the administrator Felch, and asked awkwardly, "Mr. Felch?"

"It's Professor Hepp, I thought..." Felch muttered, "I was chasing Pipi ghost just now. He got a bubble gun from somewhere. The ceiling was full of colorful bubbles... Maybe it was Joko's new product, I must report it..."

Felix waited for Felch to leave without saying a word. "Bang! Bang!" He knocked twice more, and the armor seemed to finally couldn't stand it. He opened the mask on the helmet and began to retching.

"By the way, Professor Hepp, I want to ask." Felch, who had already left, was back with an embarrassment and flattering expression on his face, but when he saw Felix's movements, he was stunned. Felix also had a headache. He just wanted to check this strange armor.

At this moment, the armor was exaggeratedly hiding, and opened its mouth and spit out a red envelope. The envelope slowly fell from the air under the gaze of the two.

"Oh." Felix said softly, he recognized what it was. The roaring letter began to smoke and then burned. He stepped back and grabbed it, confining the sound to the foyer. After a few seconds, it was amplified hundreds of times, and the cheerful voice of the Weasley twins sounded:

"Whether you are a Pipi or Filch or a little head who failed the exam or"

Fred and George's voices alternated:

“You are great”

"Of course it's also naughty."

“Adventurous”

"Catched countless times"

“Indomitable”

“It’s not correct after repeated instruction”

"The No. 1 bad guy!" The voice began to gather here, and Felch's face was purple. The roar letter continued to roll happily in the air, "Action quickly! We have provided you with sufficient help, provided that you and I have a good relationship!"

"Bang!" The roaring letter exploded into a ball of flame, and colorful fireworks flew out from it, and finally disappeared.

After an embarrassing silence.

Felix patted the gray on his body. Although he felt so angry that his teeth were itchy, he still pretended to be calm and asked: "Mr. Felch, have you forgotten what tools you brought?"

"Oh, uh, yes." Felch said vaguely, the drooping flesh on his face trembled unnaturally. When he passed by Felix, Felix heard him cursing the names of the Weasley twins.

While Felch was walking towards the office, Felix quickly slipped out of the castle. He stepped on the stone steps and took a few breaths of dry cold air before he relaxed.

Felix saw that Felch had something to say to him, and might have even prepared for a long time, but the timing just now was indeed a bit subtle. Let's talk about it later. If he heard the news that the Weasley twins were locked up, he would definitely remember what happened today.

Felix went down the steps. Seeing Valen having fun from afar, he grinned and then turned around, walked through the greenhouse and vegetable fields to the edge of the Forbidden Forest. After several phantom shifts, he was already standing by the cave where the giant Glopp lived for the winter.
