The Impact of Time Travel

"In many cases, time travel can indeed be achieved by relying on the Four-Dimensional Universe. The whole process is somewhat like loading a save file while playing a game."

Tian Yuanli's interest in the matter had risen slightly at the mention of time travel, and even the manufacturing process had slowed a little.

Xi Shenlian was not surprised.

Time travel itself was a topic that could easily pique people's interest.

If the End Empire had not maintained an extremely high level of supervision in this area for so long, then perhaps in today's world, everyone—human or ghost—would be able to travel through time, freely traverse countless timelines, and alter one another's pasts and futures at will.

Because, as mentioned before, the primary cost of time travel did not lie in technology or materials. It existed entirely with the supervising authorities and the others who might be affected.

These two factors could not be ignored. Not only could they cause time travel to fail on the spot, they could also very likely cause the person attempting it to die a violent death, instantly having their household registration and identity erased.

The so-called technology?

That was not a problem at all.

In this world, where countless civilizations could perform spacetime teleportation, create universes, and conjure resources from nothing... so-called time and the so-called River of Time could not possibly be considered untouchable.

Spacetime teleportation alone, a galaxy-level technology used for long-distance travel within the universe, already involved time to a certain extent.

As for universe-level technologies involving multiple universes or even vaster expanses of spacetime, they inevitably required in-depth research and discussion of Time Technology.

Put simply, the mysteries of time were only relative. As long as one raised their perspective, they would discover that the things involving related technology throughout the
