The Shopkeeper of All Worlds in the British Wizarding World

Chapter 5 The Magic Wand and the First Customer of the Grocery Store (revised)
After a few pleasantries, Hermione chose her wand and ran over from the counter: "Dad, look, I have a wand." Then she saw Ryan and asked in surprise, "Ryan? You want to go to Hogwarts too?"

"Yes."

At this time, Mr. Granger greeted Mr. Lambert, pulled Hermione and said, "There are still a lot of things on the list that haven't been bought. I think we should hurry." Then he said goodbye to Ryan and his son and left the wand shop.

After saying goodbye to the Grangers, Ryan came to the counter and found an energetic-looking old man standing behind the counter. This should be Mr. Ollivander. He had a pair of light-colored eyes that looked like two moons in the dim shop.

"Hello, my name is Ryan Liang. I'm going to Hogwarts this year and I need a wand." Ryan greeted a little nervously.

"Oh, a newbie, let me see what kind of wand suits you." Ollivander took out a measuring tape from his pocket. "Which arm do you use for your wand?"

"Uh, it should be the right hand." Ryan replied.

The measuring tape was wrapped around Ryan like a vine and began to automatically measure the data of every part of his body. Ollivander took this opportunity to take some boxes from the cabinet behind him. "Wands are not mass-produced. Each one is unique, so I need to find suitable users for my wands through testing."

The tape measure quickly finished measuring the body data and rolled up at Ryan's feet. "Then Mr. Ryan, try this wand, made of ebony and unicorn hair. Eight and a half inches long. Very elastic."

Ryan swung and a box suddenly flew out from the cabinet and almost hit him on the head.

It seems that the probability of hitting the bull's eye the first time is not high.

"Then try this, holly wood, snake nerve, 11 inches long"

……

When testing the seventh wand, as soon as Ryan held the handle, he felt a warm current suddenly spread from his hand to his whole body, and some sparks shot out from the head of the wand.

"Ah, great, you and this wand are a perfect match." Mr. Ollivander said with a smile.

He put the wand into a long box and wrapped it in brown paper, saying, "Pine wood, phoenix feather, twelve inches long. It is a wand that is very picky about its owner. You are very lucky."

After paying Ollivander eight Galleons, Ryan and his father left the wand shop.

After some shopping, he only had more than 70 Galleons left. Considering that Hogwarts provided food and accommodation, this amount of money was enough for the school.

Finally, they left the Leaky Cauldron, hailed a taxi, and went home with their bags.

During afternoon tea, Ms. Sally kept asking the father and son about what they had seen and heard today. It took them a lot of effort to appease the curiosity of the boss at home. While eating scones, Mr. Lambert asked Ryan: "Do you think wizards have pens that can write their own novels?"

Ryan suddenly thought of the reporter's feather pen in the fifth grade, and said, "I think wizards can make their pens move, and there may even be pens that can automatically correct errors, but Dad, the pen that you want that can write its own novels, I don't think it will exist." After listening to this, Mr. Lambert shook his head a little disappointed.

……

In the following holidays, Ryan immersed himself in studying a pile of textbooks, occasionally going to the nearby park or fast food restaurant to discuss the problems encountered in reading with Hermione Loli. To be honest, Ryan considered staying away from the protagonists, but then he thought that as an eleven-year-old child, it was suspicious to start alienating the only acquaintance who could go with him after knowing that he was going to a strange place, so it would be better to let nature take its course in the future.

Since this period of time was the only time before adulthood when one could cast spells in the non-magical world, Ryan used all the spells in the book during these twenty days. Unfortunately, only some very simple spells could be used. It seems that spells cannot be used just by knowing the spells, just like one cannot practice martial arts by just reading secret books.

On the last night before going to Hogwarts, Ryan packed his luggage and prepared to go to bed early. Suddenly, a prompt sounded from the system in his mind.

If you have guests, please do a good job of reception.

Ryan immediately got up and packed up. After thinking for a while, he packed some extra magical plant seeds and cultivation manuals he bought in Diagon Alley into a bag and chose to go to the grocery store.

Entering the grocery store, Ryan found that there was no change here from the last time he left, except that next to the flower pots on the shelf, there was a glass bottle with a bunch of soybean-sized, golden particles in it.

Take the bottle. A message comes over.

——Sunshine Crystal, a specialty of small planting bases, light-producing plants produce one every two hours. It can be used to catalyze plant growth and provide sunlight.

——How to use, when initiating, you need to bury the roots of the plants and meet the water and fertilizer requirements. When you need sunlight, please soak the crystals in water, which can provide one hour of sunlight at noon at the equator within a radius of five meters. Of course, if you crush it, you can get a three-second burst of five times the brightness of sunlight. Ryan asked the system to plant the new plants in his yard before, because zombies would not be interested when no one was in the house, so except for the outermost pea shooters, other places were planted with sunlight mushrooms and sunflowers in half. Now that small yard is full of them, more than a hundred sunlight crystals can be produced a day.

After looking at the new items, Ryan sat behind the counter and asked the system to let the customer in. The air at the door was distorted, and a middle-aged white man in a heavy fur coat walked in. There was thick snow on his shoulders, as if he had just come from the ice and snow.

After the man came in, he probably felt a little hot and unbuttoned his clothes. Ryan found that he was wearing a gorgeous Victorian-style dress underneath.

He saw Ryan behind the counter with an expression of disbelief, and his steps paused for a moment, but he finally walked to the counter and said seriously: "My son, my people and I are in trouble. When we were about to despair, I was guided here by a voice from the dark. I hope fate is not playing a cruel joke on me."

Ryan said: "Can you tell me what the problem is? Only if I know what happened can I be sure if I can help you."

The middle-aged man began to introduce the difficulties he was facing. From the words London, global cooling, steam core and winter home in his words, Ryan knew that this uncle came from the winter home in the previous life game Frostpunk. They were the people who chose to leave on the dreadnought after the energy tower exploded. However, the difficulty of this transfer exceeded expectations, which led to the difficulties they encountered now.

Sure enough, the uncle spoke: "Our world has suddenly entered a severe ice age. The surviving humans can only form settlements with steam energy towers as the core and survive on the heat and energy provided by them. But there was a problem with the energy tower in our settlement, so we had no choice but to leave and migrate. This decision was correct. We saw that the energy tower was completely destroyed in the explosion when we just left. Now most of us survivors can only rely on dreadnoughts that can move on the ice to find a new place to stay, but we haven't found one yet, and the supplies are insufficient. I..."

At this point, this iron-willed uncle actually covered his face with his hands and started crying. It seemed that as a leader, he was under too much pressure.

Hearing this, Ryan raised his hand and patted the master's shoulder to comfort him. Then he began to recommend the plants in his hand to the middle-aged man: "I have three plants here, which should be able to solve your current problem."

The uncle looked up excitedly and asked, "Really?"

"Of course it's true." Ryan said, "Two of these plants can produce sunlight during the day and at night respectively, and the other one can normally produce 7 to 10 peas the size of an adult's fist every day. After grinding, each pea can make enough pea soup to meet the needs of an adult for a day."

After listening to the detailed introduction, the middle-aged man excitedly grabbed Ryan's hand and kept thanking him. After he calmed down a little, Ryan asked, "I want an equal exchange here. What do you plan to exchange with me?"

The middle-aged man was stunned for a moment: "We left England in a hurry and only brought survival supplies, not money."

Ryan looked at the valuation table given by the system and said, "I can't use your paper money either. I have a wide range of payment methods here, from precious metals, materials to technology. What I provide can save your lives. Correspondingly, you should also bring out something of similar value."

The man thought for a moment and said, "Give me the seedlings and breeding techniques of these three plants, and I'll exchange them with you for our most critical differential engine, energy tower, and robot technology."

"Deal, although your technology tree is completely different from mine, and I'm sure I can't use it." As soon as Ryan finished speaking, a space door appeared next to the man, and a golden light band flowed out and turned into a book on the empty shelf. The book had a golden cover and it said "Winter House Industrial Manual".

After confirming that the payment had been received, Ryan put all the plants except the ones he had planted and a book in a bag and handed it to the middle-aged man. At the same time, he handed over the bottle filled with sunlight crystals: "It takes time for plants to grow and reproduce. You can use this as an emergency measure."

The middle-aged man's eyes were a little moist, and he took out an exquisite gold-shell pocket watch from his arms and put it in Ryan's hand. "Thank you for your help. This is the most valuable thing I have. I hope this can express my gratitude to you."

After saying that, he bowed to Ryan, turned around and left, dragging the big cloth bag containing the plants.

At this time, a voice came from the system——

You saved a city, changed its fate, and gained 3 deflection points——

Offset point? What is this?
Ryan looked at the system display panel and found that in addition to the connected world, a new data column for offset points was added.

It turns out that every time his actions affect the original fate of a world, he can obtain different numbers of offset points depending on the degree and the world.

The offset points can be used to randomly open the door to a certain world or to open the door to the world of the customers who have been to the grocery store. They can also be used to master power. In the grocery store, ordinary knowledge materials obtained from transactions can be instilled into Ryan's brain for free. However, in terms of extraordinary power, the more different the extraordinary power from Ryan's world is, the more offset points are needed for rapid learning.

For example, if Ryan wants to learn internal strength, it would take time and luck to learn it just by reading books and listening to explanations. After using the offset points, he can master it instantly.

After figuring out the purpose of the offset point, Ryan opened a space gate and went to the Plants vs. Zombies world to give the promised magic plant seeds to Crazy Dave.

Ten minutes later, Ryan appeared in the grocery store empty-handed, because Dave said that he could only decide the reward after determining the purpose of these seeds. Fortunately, the system prompted that his seeds provided inspiration for Dave's new plant development, so he obtained 1 offset point.

After dealing with all this, Ryan left the grocery store and returned to his bed, waiting for the time to go to Hogwarts the next day.
