Thanks for the invitation, I just entered the chat group after traveling through Under One Person.

Chapter 178 Parallel World
"Shall we go and cause trouble for the Holy Lord now?" Xiaoyu couldn't wait to set off.

“No, before that, we need to go to Venice first. Anyway, no matter where we are, the talisman is in our hands, and they will naturally come looking for us.” Cheng Yiyi thought for a moment and did not intend to confront the Mafia's Holy Lord Daolong and his gang directly.

Upon hearing this, Er Qiao roughly understood Cheng Yiyi's goal and couldn't help but glance at her in surprise.

"What kind of look is that?!" Cheng Yiyi also keenly noticed Er Qiao's gaze.

"I didn't expect you to be so smart. I thought you were just as clear-headed and stupid as I thought," Er Qiao said bluntly.

"I was just hiding my true abilities, okay?" Cheng Yiyi raised her head and said.

"Also?" Ai Haibara caught a word in Joseph Joestar's words. Where did this "also" come from? Well, after glancing at the still somewhat confused Song Shuhang, Ai Haibara knew who he was talking about.

"What are we going to Venice for?" Song Shuhang knew he might not be as quick-witted as these people, but he was eager to learn and would ask questions whenever he didn't understand. After all, that's what he did when he was working for Senior Bai.

“The Eye of Aurora,” Joe said, “Venice has a treasure called the Eye of Aurora. We need to get our hands on it first.”

The Eye of Aurora is one of the most practical magical items. It has the power to teleport people around the world. Just say the location you want to go and you can move there at will.

The usage is also very simple. Just take this necklace and say you want to go back to a certain place, and you can directly reach the corresponding location, even if you have never been to that place before.

If they came to the adventure world just for magical items, there's no need for such a rush. But if they want to collect magical items while also engaging in a tense and exciting battle between good and evil, then they need to hurry.

Only by obtaining the Eye of Aurora can one use its worldwide teleportation ability to collect magical items from all over the world at the fastest speed.

Rick and Morty possess the teleportation gun; if they wanted, these magical items wouldn't be theirs. Glancing at the livestream, Rick's immediate target was Shendu's Complete Book of Magic.

Among those present who knew about this, apart from Song Shuhang, they could probably guess that Rick was probably going to do what Xiaoyu did, making Morty the controller of the Shadow Legion, thereby taking the dominant position in the Dark Faction.

"It seems Rick and Morty went to find the Book of Time." Ai Haibara, who was watching the live stream, saw Rick fire a gun and open a portal. Passing through the portal, they arrived at an ancient hall, which led directly into the interior of the pyramid.

Although there are no historical records, it's not hard to guess where Rick and his friends are based on the architectural style here.

Aside from Xiaoyu and Chen Long, everyone else's eyes were fixed on the live stream. In the live stream, Rick, wearing a white lab coat and carrying a teleportation gun, seemed to sense they were watching. He waved his other hand at the camera, and then the live stream was abruptly cut off. They had no way of knowing what Rick was doing.

“Rick and his crew are already in the Book of Time. Knowing his style, he'll definitely do something with it, but it certainly won't be like how Shendu altered the entire history; that's not the kind of adventure Rick likes. We need to speed things up here too,” Cheng Yiyi quickly said.

"Chen Long, quickly prepare the transportation to Venice." The old man understood the urgency of the situation and ordered Chen Long to go.

"I've already contacted District 13 to book our tickets to Venice. Let's pack our bags and head to the airport now," Chen Long said, shaking his phone.

"Oh my, Dad's good nephew has grown up." Dad also praised Chen Long's clever move.

“We don’t need luggage. Once we get the Eye of Aurora, we can teleport anywhere in the world and come back anytime.” Ai Haibara stood on a chair, barely managing to keep her height from being much shorter than the others. On a high platform at the top of the steps, a huge, ancient book was placed there—the Book of Time, which could rewrite the history of this world.

"Rick, are we sure there won't be any problems using this?" Morty had also seen the videos about the Adventure World in the chat group, so he naturally knew the powerful function of this book of time.

"Motty, what are you worried about? This book is here for people to use, isn't it?" Rick spat, stepped forward, and pushed aside the dawdling Morty. With his intelligence, it wasn't hard for him to guess that such an epic item as the Book of Time was placed here as a safety net.

This world is in a balance of yin and yang. Whether it is righteous energy or dark energy, as long as one side is completely defeated, the whole world will be greatly affected.

With the annals of history as their foundation, regardless of whether one is on the righteous or evil side, even at the lowest point, there is always a sliver of possibility for a reversal. The turning point from adversity to prosperity, the shift from yin to yang, is probably why the annals of history are so clearly laid out here.

"Rick, are we going to cause any trouble by doing this? This world doesn't have our world, with so many parallel worlds for you to mess with." Morty already had the Tara tattoo on his arm, but it was relatively new, and his mind hadn't been corrupted yet. Otherwise, he wouldn't have been dawdling here until Rick couldn't stand it anymore.

"How do you know there are no parallel worlds? Do you even know the differences between them?" Rick glanced at Morty with disdain. How dare a mediocre elementary school student like Morty discuss parallel worlds with him?

There are many theoretical classifications of parallel worlds, but they are all concepts derived from four types.

The first possibility is a universe outside the universe, that is, beyond the event horizon. If space is infinite and matter is distributed sufficiently uniformly over large areas, then even the most unlikely events must occur somewhere, such as between two very similar spaces.

The second type is the inflation bubble, where parallel worlds exist in different times and spaces. The colorful orbs of light that appeared in the Ultraman Zero movie produced by Tsuburaya Productions when Ultraman Zero used the power of the entire Land of Light to travel through parallel universes were based on this theory.

Furthermore, the basis for time travel is also that the spatial expansion between different cosmic clusters, with the speed at which space expands and creates new volumes, far exceeds the speed at which it can be traversed. Theoretically, it is possible to travel to any parallel world.

The third interpretation is the many-worlds interpretation in quantum mechanics. This is similar to the constantly branching scenario in the Marvel Universe. As long as a quantum event can have random outcomes, then all outcomes will actually occur, each forming a branch.

When faced with a choice, different decisions can create a branch, resulting in two parallel universes. The subsequent development of these parallel universes will differ depending on the choices made. This theory is the concept of spacetime derived from quantum mechanics, which many people frequently cite.

The fourth type is the ultimate set. Compared to the first three types of parallel world theories, this one is more abstract and difficult to understand because it is a mathematical model. And when it comes to mathematics, everyone who understands it understands it; if you don't understand it, you don't even have the ability to pretend to understand it.

The worlds in which Su Yun, Cheng Yiyi, Yi Qing, and the other transmigrators resided, derived from the original world, were mostly similar to the third type: quantum parallel universes. Their transmigration caused the original world to branch out, forming derivative worlds.

The most common parallel universes in science fiction are quantum parallel universes. Of course, the second type, inflationary bubble, also exists, but it's more applicable to the multiverse scenario. Furthermore, the second and third types of parallel worlds are not contradictory.

The second type of parallel universe is like a series of independent bubbles; to travel from one world to another, one needs to pass through a "membrane" in between. Quantum parallel universes, on the other hand, are splits from the original world.

For example, in a world where one person transmigrates, each transmigrator corresponds to a split, derivative world. All these worlds combined form a large bubble, and next to this large bubble is another large bubble, resulting in eighty-one worlds.

However, no matter what type of parallel world you want to experience, you can find the corresponding type in the Rick Universe. The mechanism of the Rick Universe is an infinite number of parallel worlds. Even if there is no parallel world of this type in the finite universe, there must be one in the infinite parallel universes outside the walls.
