This plan is the last plan, the plan that has to be started after all plans have failed.

Travel back in time and turn history.

After having the ability, Yuntian refused to travel through time and space because it meant uncertainty.

When space and time are reversed, then anything can happen.

Traveling through time and space also means the emergence of space-time paradoxes, or the generation of causal inversion, and time falls into a loop of closing connections.

But now, there is only this way to resurrect Xiao Yi in the true sense.

Yun Tian returned to the Xuantian Realm, sat directly on the ground, pulled out the analog keyboard in the void, and began to code words.

A short story about the theme of traveling through time and space.

Why do so many film and television themes that travel through time and space, Yuntian not go directly, but write them by himself?

The moonlight treasure box of "Journey to the West", the time machine of "Doraemon", and the time machine of "Terminator", there are too many such themes, why do you still design your own, isn't it too much?

Because these time machines have their own unique ways of using them and the rules of the world.

The Moonlight Treasure Box cannot travel through time exactly, and will produce variables that change the world, which should be avoided.

And a time machine like Doraemon, in the plot of a special time machine, constitutes a ring of closing connection, which means that you are destined in the past.

This sense of fatalism is something that Yun Tian tries his best to avoid, and the ghost knows whether fate is destined to succeed or fail.

Of course, some Doraemon theatrical versions can change the future, and there is no unified standard time machine for this setting, and Yuntian dare not use it.

The time machine of "Terminator" is also a truth, thinking that the past has changed, but not knowing that everything you are trying to do is the past.

What a sorrow.

There is also an explosion plot of becoming his own grandfather......

The time machines of these worlds are all rules of time given by the author.

Worldviews such as these have a history that cannot be changed, and even if the traversal is successful, the world will automatically prevent you from changing the known history.

You want to see yourself after crossing over, but suddenly you have a car accident, so you hang, history still hasn't changed, this is a more tragic view of time and space that cannot change history.

If you have to go to see yourself after escaping a car accident and have a time paradox, then congratulations, you are the enemy of the world through which you have traveled, just like "Death is Coming", the world comes alive against you.

Yun Tian used to think it was interesting to see the setting of the Ring of Time, but now when he becomes the real protagonist, he doesn't think so.

The Ring of Time thinks that the past is predestined, and after you cross over, you think you are changing everything, but in the end you can't do anything, and even some fucking things are caused by your own accidents, which would not have happened if you hadn't crossed by yourself.

But this assumption does not exist, it is fate that you will travel through time and space, and it is fate that you will do everything.

Therefore, the worldview of all the works is not what Yuntian wants.

If it is a space-time machine measured by science and technology, if it is observed, it may not be able to cross, because the root of the laws of time and space is different.

If it is a magic weapon of time and space in the mysterious survey, it may be possible to travel through the observation, but it may lead the clouds to other places.

Therefore, Yuntian needs to set up the world by himself and set up a machine that conforms to reality and travels through time and space.

Yuntian did not add any settings to time and space in this story, everything depends on the world's own brain to make up for it, so that such a machine can be used in reality.

The plot is very simple, that is, the protagonist is a member of the National Academy of Sciences, and by chance he created a time machine, and then conducted the first experiment.

This is where the story comes to an abrupt end, the success of the experiment is inevitable, but what happened, is not written.

Yuntian does not set time and space to be unchangeable, nor does it set the ring of time and space, nor does it set the butterfly effect.

Everything depends on the self-setting of reality, and the setting of reality Yuntian can't interfere with it, so he can only rely on his own exploration, but Yuntian feels that the laws of the objective universe are very likely to be ......

Irreversible history or split parallel universes.

Suppose Yuntian uses a time machine to go back in time and appear in the place where Xiao Yi changed at the same time, what will happen?

Cloudy Sky will certainly change all that.

But the scene at that time Yuntian did not appear, and at this time he appeared and saved Xiao Yi, and Xiao Yi did not die.

Then the question comes, everything will change after Xiao Yi is not dead, what is the timeline of Xiao Yi's death experienced by Yuntian?

In order to avoid this situation, the objective world will not change history, but let the cloud sky travel fail, or stop him with accidents.

This is case one.

The second situation is that the cloud sky appears, and the world line is split into the cloud sky crossing and successfully saves Xiao Yi, and the cloud sky crossing fails or an accident occurs and Xiao Yi dies.

The division of the world into two parallel worlds continues.

In this case, Yuntian is equivalent to losing, the history of Xiao Yi's death has not changed, and the living Xiao Yi is also another time and space.

But fortunately, the existence of the soul allows Yuntian to avoid the above two points and solve all this with a other method that is less costly.

"This article on time machines is called "Time Machine"."

……

The Academy of Sciences is boiling over, because today, an epoch-making time machine is born.

Scientists once used a nano-scale miniature camera to use a time machine to put it back a thousand years and take pictures of ancient people.

Putting this kind of miniature camera cannot interfere with reality, and thus avoid the occurrence of paradoxes, as well as the change of history, or the generation of displacement of time and space.

Now, mad scientists have decided to conduct a history-changing test, in vivo experiments.

They plan to conduct many experiments to find out the laws of time and space.

Today is the moment in history, Subject 001, which will travel to five minutes ago.

In fact, this time machine is not studied by scientific theories, but by coincidence.

Like a group of monkeys pressing a keyboard and eventually typing out a work by Shakespeare, scientists stumble together a time machine.

This probability is very low, but it is not impossible, even though it may be as low as the probability of taking the whole universe particles as the denominator and the whole universe as the numerator, but it still happens.

Because it's a cloudy setting.

The formula theorem means that the rules of time and space are clear, and the rules of time and space in this world are different from reality.

So Yuntian was designed as a time machine that was accidentally patchworked, and then used by mad scientists to finally reverse the laws of time and space.

It's just that there is no ending, and the ending comes to an abrupt end when Experimenter 001 enters the time machine.

Just as 001 was about to enter the time machine, there was a fluctuation in the air, and a figure in black armor appeared directly in everyone's eyes.

The crowd who felt that they were witnessing history and were excited instantly got stuck and didn't know what to say.

"I am the Lord of the Xuantian Realm of the Pan-Plane Space-Time Administration, maintaining the peace and stability of space-time."

"Your actions will have serious consequences in the future, breaking the rules of time, so I deliberately traveled through time and space to change all this."

With a wave of his hand, the black light shone, the time machine disappeared completely, and the clouds disappeared in place.

The scientists looked at each other in bewilderment......
