The Shopkeeper of All Worlds in the British Wizarding World

Chapter 109: Secret Chamber Preparation
After exploring the secret room, Ryan opened the space door leading to the world of Plants vs. Zombies and went in.

With the help of robots, the city was built very quickly. The fortress that was only planned on the blueprint when I came here last time was almost built. Ryan found Kenway here who had just returned from vacation at sea.

"Good afternoon, Kenway. You seem to be having a good time. I have something to do with Dave, can you tell me where he is?"

"I heard that the spider you sent last time gave Dave a lot of inspiration. He has been in the laboratory all day these days, tinkering with something. But he has told me to take you there when you come to ask him for something."

After that, Kenway put down the coffee cup in his hand and walked towards the warehouse with Ryan. As they walked, he said to Ryan, "I think you look good in this assassin uniform. At least it looks better than the black robe you wore last time."

As they talked, the two men came to the entrance of the underground warehouse. After showing their metal identification cards, the warehouse guard opened the heavy door for them.

After stepping into the warehouse, Kenway opened the door of the innermost warehouse. Ryan saw that the shelves were full of what he wanted.

"It looks like you're dealing with a big one now. I can only give you one piece of advice, that is, big ones are often very strong in their lives, so don't approach them rashly before you make sure they're dead." After saying that, Kenway waved his hand and turned to leave, closing the warehouse door behind him.

This is very good advice. Ryan took note of it and began to count the prepared weapons.

These weapons, of two types, were operated by clockwork-powered pocket mechanical difference engines, which Ryan had strongly requested, as he was concerned that using electricity might fail within the confines of Hogwarts.

One type of weapon is ten weapon stations, each with three parallel harpoon guns. These harpoon guns are single-shot weapons that fire explosive-tipped darts used to hunt whales through gunpowder.

Fortunately, hot weapons can be used in Hogwarts, because Ryan found out in the school history that Peeves once fired a cannon in the castle in the 19th century.

Another weapon is a cleverly designed steel crossbow that can fire five javelins with explosive heads in a row. However, this thing is more difficult to make, so there are only five of them.

All weapons are controlled by the differential engine, and Ryan sets them to fire in predetermined directions.

Finally, there are thin copper plates with patterns engraved on them. The grooves of the patterns are inlaid with thin silver wires. The copper plates are numbered for easy positioning. These copper plates and silver wires were blended with a large amount of sunlight crystals when the raw materials were first smelted. This is a new discovery in the world of Plants vs. Zombies. At that time, the workers found that adding sunlight crystals to the smelting process of metal raw materials can effectively shorten the smelting time.

When Ryan fought against the Acromanthus last time, he found that some repaired parts of the Gatling gun had positive energy reflections. After asking, he learned about the existence of this metal. So he specified that the things he needed must be made of this newly smelted metal.

That's why it took several months to make just these few things, because the Plants vs. Zombies world now generally recycles old metals and simply processes them to make items. If you want this kind of new metal, you need to customize it individually, so the manufacturing speed is naturally not that fast.

After counting the supplies, Ryan opened the space door leading to the secret room and pushed the items into the secret room with a cart, and then began to arrange them. He first took out the copper plates, placed them at each node position according to the predetermined orientation, and finally formed a magic circle. Then he took out a bottle of potion from the space bag and dripped a few drops on each copper plate.

This potion is made from the blood of the giant spider. In order to balance the yin and yang, Ryan melted a few strands of unicorn tail hair into it. The finished potion is a good conductor of magic.

As the potion dripped, the copper plate absorbed the potion as if it had come alive. After the potion was completely absorbed by the copper plate, the silver wire inlaid on the copper plate emitted a faint glow.

Finally, Ryan used a brush dipped in potion to draw a magic circle on the ground, connecting all the copper plates together to form a whole.

When the last stroke was completed, the magic circle suddenly burst into a strong white light, and then all the metal plates turned into liquid and flowed on the ground along the previously drawn pattern. Finally, a magic circle covering a large area was formed in front of the statue.

After the light dimmed, Ryan walked to the center of the magic circle and found that the melted metal plates had turned into metal wires embedded in the floor of the secret room, forming the current magic circle emitting a bright white light.

He pulled out his hidden blade, cut his finger and let the blood drip onto the center of the formation, so that he could control the demon-binding formation that had already been set up.

This array comes from the content of Maoshan Taoist scriptures. In the past, before the end of the law era, this was one of the arrays used by Maoshan sect to capture large monsters. Compared with other methods, the biggest advantage of this method is that it only requires one person to operate, and the operator's cultivation level is not high. However, this array has been used very few times in history.

On the one hand, this magic array cannot be moved after it is set up, so it is not as flexible as a few people setting up a formation. On the other hand, copper and silver were money in ancient times, and the things consumed in setting up the magic array were enough to invite strong people to take action. At that time, not many people were willing to spend money on such things.

However, for Ryan, the magic array that can be used by one person and does not require high cultivation level is his favorite. The consumed silver and copper are not so precious to him. And the basilisk has only one exit, and the magic array is used to block the door, so it is not a problem that it cannot be moved.

After Ryan was able to completely control the magic circle, it restrained all the light and aura, making the floor look no different from before.

After the most important magic circle was completed, Ryan arranged 15 weapon stations according to the optimal solution calculated by everyone in the previous Plants vs. Zombies world. Then he embedded the armor-breaking spells that he had drawn on the spider shell in advance into the empty slots left on the arrows during production.

These runes are exactly why Ryan did not choose firearms, because he was not sure that he could condense so many runes on a small bullet. Not to mention that the use environment of a bullet is much worse than that of an arrow. It is very likely that the high temperature and high speed will destroy the magic on the bullet.

Finally, Ryan launched the hook on his left arm to the side of a pillar, where a cage containing a rooster was also placed. In this way, after opening the entrance and exit of the basilisk, he could get away from danger as quickly as possible and use the rooster to weaken the basilisk as soon as possible.
