Why can t I cross up, why can t I cross?

Corrupted files, or incompatible, the former is more likely.

You can only travel to the future (science and technology), but you can never travel back.

You have to be able to travel back in time, I'll eat live !!

There are three ways to traverse: 1. Speed exceeds the speed of light, 2. Wormholes, 3. Black holes.

Because your soul is not out of the body yet.

Not necessarily, ** is only crossed after death.

Eh, this is the poison of **!

Because you're still alive to fool around!

Because you're not moving faster than the speed of light!

Traveling is not limited to going back to the past, but also traveling to the future, for example (if living from one's own time and space to the future is also crossing 0, or traveling to a parallel space, a parallel world, a parallel universe, or the same time and space and the same era, A travels to B. It is also possible to wear it empty, to a distant era with no historical record, or it can be said to be under the probability of one in a thousand.

Can people really cross over?

I don't know

Because none of the people who wore it ever wore it back again

I don't know

Because I haven't worn it yet

Generally those who crossed were dead. Because if you want to travel like a person, you have to decompose the city ion state before you can cross it.

Traversal is short for traversing time and space. In layman's terms, it refers to an event in which a character travels from time and space (time and space) to another time and space (time and space) (time and space B) for a certain reason. At the same time, crossing is also an outdoor sport.

Different from the rigorous scientific speech of "crossing time and space", "crossing" is widely used in literature as a special plot of the plot, and in recent years, historical texts, overhead texts and otherworldly texts have also become very popular on the Internet, and we collectively refer to this kind of ** as "crossing**".

Crossing is to say that the male (or female) protagonist returns to the ancient (or modern or future) from the modern (or ancient) for some reason...And then there is a love story. Start a business again. Be an emperor. Dominate the harem and so on.

It is a modern person who inexplicably came to ancient times due to an accident, or a car accident, or technology, or touched an ancient thing, or an ancient person came to modern times due to chance. The typical is the TV series "Palace". ** "Dream Back to the Qing Dynasty".
