Once Rei was done cultivating, only needing to wait for his cultivation technique to complete the mixing of consciousness and Qi, he stood up and left the bedroom, going behind the counter.
It was time for his first customer.
'Who should I bring here as my first customer? Definitely someone who needs or wants knowledge, if possible a good guy I know about... Well, let's just give these specifications to the door and see who I end up with!'
Soon after, the door opened and out came Albus Dumbledore himself!
"Hmm, this doesn't seem to be the Honeypot. Would you mind telling me where this is and how I got here, young man?"
"Not at all, Professor Dumbledore. This Place is the Akashik Cafè, a multiversal bookcafè, containing every bit of knowledge from the past, present and future of the entire Multiverse. I am the Owner and the only employee of this shop, Rei Suzuki. Please call me Rei. And as to how you got here, well, the door you came through is connected to all the places and timelines in the entire multiverse, and is programmed to find those in need of, or with thirst for, knowledge and allow them to enter this place."
"Hou... Now this seems interesting. So I can just get any knowledge I want from here?"
"Potentially? Yes. Practically? Sadly no. The Store will automatically choose a fitting book for you. In addition, you can get a card for this shop, enabeling you to enter whenever and whereever you want, while also permitting you to exchange messages with the other customers. Although currently you are the only customer I have, as we only just opened."
"Well, in that case, could I get one of those cards and my book? I would like to see what this shop can give me."
"Very well!"
After Rei said this a book came flying from the depths in between the bookshelves. On it's title there was a writing in golden letters: 'Mind Palace building: beginners'.
"Indeed, this book does fit you very well, Professor."
"Hou, why do you say that?"
"Well, this technique allows you to begin building your mind palace, in which you can store, sort and rewatch all of your knowledge and memories. Just think of it as a library containing all your knowledge and memories, much like an upgraded version of your Pensieve(his memory pool). However, this one is situated inside your sea of consciousness, not in the physical world."
"This does seem to fit me very well indeed... So all I need to do is read this and follow the steps?"
"Yes, and then, when you take back your memories from the Pensieve, they will automatically fit themselves inside. You can read and try it over there on one of those chairs, and if you want, then I can even bring you some snacks or drinks."
"Well, in that case I will go right ahead. And could I trouble you for some sweets and a cup of fitting tea?"
"Very well. Do take a seat, I will bring you your order as soon as it's finished. Would you be alright with pancakes?"
"That would be fantastic."
Directly afterwards Rei went to the kitchen, in order to cook some pancakes, not forgetting to add strawberry sauce on top. He then went ahead and started brewing tea from the leaves of the heavenly insight plant, a magical herb from cultivation worlds, calming the mind and granting better comprehension for a limited amount of time. Once he was finished, a homely, calming scent wafted through the air.
Then he went back to Professor Dumbledore, in order to deliver the pancakes and tea to him. When Rei came back into the store, the Professor was already sitting and reading the manual, however, as soon as he smelt the scent of Reis cooking, he looked up.
"Aaah, thank you Mr. Rei. This does look and smell extraordinary."
"Thank you very much for you praise. Take your time to finish up, although, if you have any appointments later today, you should set an alarm within your card, simply tell it, when you want to be notified."
"I will, thank you very much."
------- 1 and a half hours later ---------
By now, Dumbledore had been finished with the book and the cooking for half an hour, and had been trying to construct his own memory palace.
'Hmmm, he seems to have succeeded. In that case he should wake up anytime now.'
The Professor then opened his eyes and Rei could clearly see his amazement within his eyes.
"This technique truly is amazing! Thank you very much, Mr. Rei, I will be sure to visit again. What would the payment be?"
"Oh, there isn't really a payment in that sense, though you could bring all kinds of artifacts or magical creatures as payment. You won't need to bring them yourself, all you need to do, is own them and state, that you would like to use them as payment, the shop will then transfer them into a suitable storage dimension."
"Well, in that case I still have an artifact that can protect their user from an attack below a certain threshold once, if possible I would like to pay with that."
"Very well, your payment has been accepted."
"In that case, I will be going back, I need to get all those memories back into my head."
"I wish you a very pleasant rest of the day."
---------- POV Dumbledore -----------
Once I left the door I found myself back in my office at Hogwarts. I immediately took back all my memories from my Pensieve, and they really did enter my rudimentary Mind Palace immediately.
'That Shop really is mysterious... And the snacks that young man made were very delicous as well. I suppose I will have to visit every now and then. Of course, only to keep an eye on both the Shop and the owner.'
