A bright moon rose from the sea and climbed into the sky with difficulty.

Under the cloudless night, the waves wash over the reef on the shore one after another, and the mechanical repetition of the sound of the waves seems to have a cleansing power at first hearing, but after listening to it for a long time, it cannot help but disturb people's sleep. Standing in the lighthouse on a large rock, old John was already snoring deafeningly, and on the first floor, where the dim electric lights were lit, Sirius and Amosta were still busy with some business.

The flames released by the alcohol lamp scorched the crucibles on the shelves, and inside the pewter crucibles, a dark brown viscous solution was bubbling.

"Excuse me, a fifth ounce of Hoklap juice—"

Amosta looked calm, staring intently at the half-finished potion inside the cauldron, and when the brown liquid bubbled up and turned into more numerous bubbles, he commanded in a calm voice.

Sirius, who was waiting for him, immediately threw himself down on the square table against the window, squinted his eyes and rummaged through the pile of bottles and cans, and finally picked out a thumb-sized glass bottle and handed it to Amosta.

"You're giving me the secretions of the spotted man—"

Amosta didn't raise his head, staring at the bubbles and said sternly,

"That thing is a necessary ingredient for Mrs. Skoll's all-purpose stain remover, and if you want to poison your savior, I wouldn't mind putting two drops into it, Sirius--"

Sirius's heart was choked for a moment, and he quickly withdrew the hand that handed the bottle, and his eyes searched the table with difficulty.

"On your right, the light green bottle," Amosta sighed softly, a little helplessly.

With an accurate reminder, Sirius finally found something. After a fifth ounce of Hoklap juice was dropped, the brown solution immediately turned a dark green, and a puff of smoke came out. After just inhaling a little, Sirius suddenly felt a burning pain in his throat, and old John, who was separated by a layer of wood, coughed violently in his sleep.

Sirius quickly opened the window and directed the pungent smoke outside, and then, immediately looking at Amosta to ask if it had failed, he breathed a sigh of relief when he saw that Amosta was holding his wand and stirring the potion that was gradually turning from dark green to light green in seven clockwise and then counterclockwise.

"Didn't fail?"

"Don't make such a nasty joke--"

Amosta was still focused,

"If it weren't for the fact that I put a lot of thought into Charms and didn't have time to spend on a few other disciplines, I wouldn't be able to get the title of Potions Master and Magical Beasts Expert--"

Sirius breathed a sigh of relief, shrugged his shoulders and walked to the only stool in the living room

"When I was at Hogwarts, I did well in most classes, but I didn't like Potions class. I didn't like Professor Slughorn, who taught potions at the time, and that guy was always trying to convince me to leave Gryffindor and go to Slytherin—"

"I've heard something about Professor Slughorn from Dirk Chryswell, the current head of the Fairy Liaison Office at the Ministry of Magic,"

Amosta rubbed his smoky eyes,

"He seems to have a special love of dealing with gifted little wizards, hehe, it's Slytherin's style--"

"Objectively speaking, he's not particularly annoying, but it's just that this problem is a bit of a headache--"

Sirius said in a complaining tone, his ass just next to the stool, and Amosta said in a voice of urgency,

"Don't be idle, five porcupine thorns!"

Porcupine thorns were much easier to find than Hoklap juice, and this time, Sirius wasn't mistaken.

After Amosta threw the porcupine thorns into the clear solution that had taken on a green and radiant hue, the already calm liquid surface boiled again, and a large amount of water vapor evaporated from the potion, and the original half pot of solution sank at a speed visible to the naked eye, and only half a minute later, a small cloud of crystal clear liquid like autumn dew was left at the bottom of the pot.

Amosta waved his wand, and the liquid flew into a clean glass bottle, and when the flame was extinguished, Amosta twisted his neck and finally breathed a sigh of relief.

"It's finished?"

In the dim light, Sirius looked at the crystal liquid that seemed to be alive in the bottle, suspended against gravity, and his voice was slightly nervous.

"The leg injury that has lasted for half a century is indeed not easy to treat, and considering his age, I adjusted the concentration of the medicine, and the entire repair period will last about ten days, I am afraid he will not feel too well these days, but after these days, some dark injuries in his legs and body can basically heal."

"Thanks--"

Sirius clenched the bottle tightly, and he smiled sincerely as he looked at Amosta, who was taking the bottles and cans back into his suitcase on the table.

"You're even more special than Professor Slughorn, Amosta, you know what I mean, the people of that house have always been malicious towards Muggles, and you're willing to spend the effort to make healing potions for an old Muggle man with whom he didn't have much friendship, to be honest, I wouldn't have believed that there were such people in Slytherin more than ten years ago-"

Similar remarks Amosta had already heard a lot, and he waved his hand casually,

"For these two days, I like the hodgepodge that old John makes, which is even better than the elves at school."

Sirius smiled, not saying anything more.

Through the oil-stained and dust-stained glass windows, Amosta looked out, and late at night, the coolness of the air caused a thick fog to rise along the shore, and the fog was carried by the cold wind, gradually submerging the town built on the open ground.

The moonlight became hazy, and the sea in the haze seemed a little mysterious.

Just like before setting off for the 'Merlin's Eternal Resting' with the woman Vitia Cleona, Amosta had a vague premonition that something surprising would happen to her this trip. Turning his gaze back into the house, Amosta looked at Sirius, who was sneaking in and drugged Old John, with a slight hesitation in his eyes.

Going to Azkaban is not a difficult thing for him now, as long as he applies to the Ministry of Magic in the name of academic investigation, the Ministry of Magic will not save his face, but the Ministry of Magic will definitely send personnel to accompany him at that time, and if something happens, it will be difficult to deal with the aftermath.

Amosta wasn't worried that Sirius would talk about him everywhere, he was a man of love who would rather stay in Azkaban for more than a dozen years in order to redeem himself than tell the truth about his innocence, and Amosta believed that he would keep it a secret for himself, but he couldn't handle the risks of this journey

After feeding Old John the medicine and using magic to put the old man to a peaceful sleep, Sirius breathed a sigh of relief and bowed slightly to Old John, his eyes full of gratitude.

Sirius was willing to take Old John to London to live with him, but he didn't say a word all the time, because he knew that this sea was the home of the old man's soul, and Old John would not go anywhere except this.

Looking at the messy furnishings around him, Sirius grinned in the dimness.

When Harry graduated from Hogwarts and found a lifelong partner, he could move in and accompany the kind old man on his last journey.

After descending the creaking staircase, Sirius glanced at Amosta, who was standing in the doorway and looked at him, and with a single glance, Sirius was startled.

He could see a deep hesitation in Amosta's gaze in his eyes, this was not normal, he had known Amosta for a while, this guy had always been extremely decisive, and rarely felt this emotion in him.

"What's wrong, Amosta?"

"Nothing--"

Amosta withdrew his gaze and pursed his lips,

"It's just- I think you're probably aware that I'm not going to Azkaban this time with the Dementors or the criminals in the prison, I'm looking after something that might be risky-"

Sirius suddenly smiled,

"You're afraid of getting me involved?"

"That's true--"

Amosta looked calm,

"I don't want to deceive you, Sirius, I don't know what we're going to encounter, but I can tell you for sure that if there's danger, neither I nor Dumbledore will be in control. Harry's kid has finally found a relative, and if something happens to you, he'll probably break down. ”

"yes, he's definitely going to take a hit."

Sirius smiled, as if he wasn't talking about himself.

"But I believe in him, Harry is as brave as his father, even if I have some accidents one day, Harry can face life bravely, and I-"

The smile on Sirius's face became a little naughty, which made the vicissitudes of life instantly look a little bit of the once confident and flying youth,

"It's my duty to take care of Harry, Amosta, but if there's only one thing left for the rest of my life, then I might as well die in the ocean!"

The lighthouse lights dimmed in the early morning light, and Amosta was magically widening and cleaning up the rusty cabins, and they were going to spend at least two weeks on the fishing boat that John Sr. had given them, and the rest of the drifting days would not be possible without magic to fortify and make them comfortable.

Facing the cool sea breeze, Sirius raised his head and stared at the dim starry sky, the corners of his mouth raised,

"When can I go, Amosta, I can't wait to go on an adventure, oh, it's a good feeling, it reminds me of the adventure in the Forbidden Forest with Jaime and Remus!"

Covered in dust, Amosta poked his head out of the cabin, and his face was not angry,

"If you'd like to come in and help me, we might as well leave sooner!"

"Oh-"

Sirius spread his hands, looking innocent,

"I'm not very good at preparing, it used to be Peter's traitor's job—"
