"In many cases, time travel can indeed be achieved by relying on the [four-dimensional universe]. The overall operation is a bit like loading a save file when playing a game."

Looking at Tian Yuanli, who became a little interested in time travel and even slowed down the manufacturing process slightly.

Xi Shenlian was not surprised.

Time travel is a topic that can arouse people's interest.

If the [End Empire] had not long been investing a great deal of regulatory efforts in related areas, I am afraid that in today's world, both humans and ghosts could travel through time, freely move between multiple timelines, and tamper with each other's past and future.

Because as mentioned before, the main cost of time travel is not in technology or materials, but lies entirely with the regulators and others who may be affected.

These two factors that cannot be ignored may not only cause the time travel to fail, but may also cause the person trying to time travel to die on the spot, and have his household registration and residence cancelled instantly.

So-called technology?

Not a problem at all.

In this world where there are countless civilizations that can teleport through time and space, create universes, and create resources out of nothing... the so-called time and the so-called river of time cannot be considered as something untouchable.

The galaxy-level technology of space-time teleportation, which is used for long-distance travel within the universe, actually involves time to a certain extent.

As for cosmic-level technologies involving multiple universes or even larger space-time, it is inevitable to conduct in-depth research and discussion on time technology.

Therefore, to put it bluntly, the mystery of time is only a relative thing. As long as you raise your perspective, you will find that there are so many things in the world that involve related technologies that they can only be described as countless. The simplest example is natural celestial bodies such as black holes. Their excessive mass can distort the flow of time just by their existence. By simply borrowing their principles, even the most ordinary interstellar civilizations, the primitive indigenous creatures that have no way of breaking away from the universe in which they were born, can easily master some time technologies to a certain extent and change the flow of time within a certain range.

Same reason.

When technology extends to other dimensions beyond the [three-dimensional universe], time and space will no longer be something unreachable, but will only be everyone's research target.

If it weren't for the ban of the [End Empire], time machines would be everywhere.

It won’t be much more precious than the trans-dimensional battleship.

In other words, it is far less precious than the trans-dimensional battleship.

Because the trans-dimensional battleship also needs to carry additional expensive components such as weapon systems, life support systems, etc., the cost is naturally higher.

"In this world, time is something complicated but not very complicated."

"Take the universe you have created now."

"The time contained in it is, in most cases, in an introverted state, and only operates within time and space."

"This makes them the equivalent of a separate timeline."

"Unless there is a connection with the outside world, the time inside it will generally not converge with the outside world. When time has not been linked to the outside world, the act of traveling through time in it will usually not attract the attention of the official departments of the [End Empire]."

"To put it bluntly, you are essentially just playing a single-player game, so the other party naturally has no time to care about you."

If everyone is playing games.

Then, the time and space created by Tian Yuanli belongs to a private room, a local area network, a stand-alone game... The various records and data contained therein have basically nothing to do with outsiders.

Then, as we all know.

Just don't disturb others when you play games.

Then, no one will care whether you are retracing or doing other actions.

Here, the so-called time travel can be regarded as choosing to reload the game and start over when playing a single-player game.

Compared to this closed and self-entertaining place, the time and space outside are completely different. It belongs to the online game.

If you want to load the game file there, it will undoubtedly affect the entire server and directly affect the data and gaming experience of other players.

therefore.

The official will naturally delete your account.

The other players will naturally beat you up.

Moreover, the real world is not comparable to a simple online game after all...

When things involve life or even more important interests.

It's impossible for things to be as simple as deleting your account and beating you up.

Instead, they will completely destroy your humanity and won't even give you the chance to create another account and be reborn.

"Does this mean that as long as I am in the current time and space, I can actually travel through time lines at will in the future?"

"right."

While nodding in response to Tian Yuanli's inquiry, Xi Shenlian also said:

"In fact, if you study the secondary permissions I gave you before, you will find that within the entire [Purple Dream Sky Company], you can actually travel through time at will."

"Even after traveling through time, everything you do will affect many outsiders..."

Upon hearing this, Tian Yuanli was a little confused.

"Outsider?"

"... [Purple Fantasy Sky Company] is a large space-time connected to the outside world. If changes in the timeline affect outsiders, wouldn't the related impact immediately spread to the external space-time?"

Different from her new time and space which is like a stand-alone game.

Xi Shenlian's [Purple Fantasy Sky Company] is a semi-open super-large space-time. There are a large number of people, materials, energy, information... coming in and out every moment, so the timeline of the entire [Purple Fantasy Sky Company] is naturally closely related to the outside timeline, just like networked data. Therefore, once the timeline here is modified, it will easily affect the outside world.

for example:

Originally, there were N people who ran away from the [Purple Dream Sky Company] to N completely different time and space.

And those N people will have various impacts, big and small, on each time and space.

However, when the timeline of [Purple Fantasy Sky Company] was tampered with, the number and ideas of the N people who were supposed to go to different time and space were likely to change, which would directly lead to various chain reactions extending continuously, causing the original facts of each time and space to change accordingly. The guy who was supposed to arrive at a certain place and cause a big event did not arrive there, and the guy who was supposed to die did not die... In the end, things would inevitably become an emergency that affects the entire world, triggering a super-large-scale butterfly effect, and all kinds of things that should not happen happened crazily, and all kinds of things that should have happened were inexplicably stillborn...
