We usually see similar things like Ye Feng sacrificing the power of the Demon King to return to the present in some movies and TV series, such as the movie The Terminator, which simply describes time travel. Through the time machine, the protagonist can easily go back to the past or reach the future. As an audience, we only see the results, but as for time travel itself, there are no answers in the movie.
In fact, many traditional physicists do not endorse time travel. There are many reasons for their rejection, the most important of which is the "time paradox". The most famous one is the grandfather paradox, which means that when you go back in time and kill your grandfather, from the moment you kill your grandfather, things related to your grandfather will change. Since your grandfather is dead , naturally you would not have been born without your father, and without your father, naturally there would be no more you. Since you no longer exist, who killed your grandfather? It’s simply a modern version of the “chicken or the egg” question.
Therefore, some physicists believe that time travel is impossible because it does not conform to scientific logic and cannot be explained. Therefore, if the "time paradox" cannot be explained scientifically, it is enough to rule out the possibility of time travel.
However, according to Einstein's theory of relativity, traveling through time and space does not violate the current laws of physics, but the existence of time paradox makes time and space travel unreasonable. Therefore, someone proposed the theory of parallel universes, which can solve the time paradox very well and convince many people.
This view holds that there are parallel universes connected to the world in which we exist. Take the grandfather paradox as an example. When the protagonist of the story goes back in time, he is split into two different worlds the moment he changes the past. One is a world in which his grandfather did not die, and the other is a world in which his grandfather died. This breaks the doubts caused by the time paradox.
From the current situation, as far as Ye Feng is concerned, Ye Feng knows that there are parallel universes on the same timeline, and that when human power reaches at least the sixth dimension, "time travel" can be achieved.
But this time, Ye Feng's handling method was a little different. Even though he changed the past of the death of Ren Xiaojin and others, he did not allow the birth of a parallel universe, because Ye Feng would not allow the birth of another parallel universe line in which Ren Xiaojin and others died. , so he destroyed the original parallel universe line, then the original so-called grandfather paradox is no longer valid, because only on the original universe line, the logical relationship of time exists, but since the original universe line disappeared, Then the logical relationship disappears.
To put it simply, as far as the grandfather paradox is concerned, it is because of the annihilation and disappearance of the original parallel universe rays. You, who were supposed to be your grandfather's grandson, are no longer your grandfather's grandson. There is no logical relationship between you and your grandfather in time and space. At that time, even if you kill your grandfather, it will no longer affect your existential issues. Naturally, there will not be two parallel universe lines.
For the demon world that was originally blocked by the Lock of Heaven at this moment, the demon king army brought back by Ye Feng was a hungry tiger that suddenly appeared among the sheep. The original aborigines of the demon world were unable to resist it.
For the Demon King's Army, just like the previous analogy with the single-player game, at this moment they are just clearing a week of advanced equipment and high levels on normal difficulty, and then clearing it on normal difficulty again is boring. But after all, there are so many strong men in the Demon King's Army, and they need living space. And it seems that the natives of the demon world will not give up their territory. However, the "turf grabbing" thing is too normal and familiar to the Demon King's Army. In addition, there is no fundamental problem of the "grandfather paradox of time paradox" today. There is no situation where my own existence disappears after I kill so and so. Then you have to grab it.
The strong are destined to conquer the weak. If the weak surrender and are conquered, there is no need to fight. However, if there is a situation of "conquering the enemy without fighting", then this is not a demon world. Therefore, going to the Demon Realm is inevitable.
Of course, now that the Demon King's army has arrived in the Demon Realm, it is like a drop of thick ink dropped into a bucket of clear water. Then this bucket of water is destined to be dyed black.
The Demon King's army is divided into eight armies to conquer, so the place with the most enemies is the place with the most military exploits. All of Ye Feng's demon clan members want to take the greatest credit and dedicate it to the demon king "Ye Feng". After all, everyone wants to be Ye Feng's confidant. Maybe you can't be as close as a partner like Gan Xue, after all, it's incomparable. But positions like Bai Ze, Bifang, and Taotie can still be fought for. What's more, the brainless monkey of the Ape Demon is closer to the Demon King than he is. How can he tolerate this?
But Gan Xue needs someone to vent his anger on. In the past, when the Demon King temporarily left the Demon King's army to explore the layout of other worlds, once Gan Xue was left behind, Gan Xue would lose his temper everywhere. The demons did not dare to get angry or speak out. Most of them are avoiding this ancestor. And if the Demon King goes to lay out the plan and takes Gan Xue with him, the rest of the Demon King's army will party all night long on the night when the two of them leave.
So to be honest, in addition to wanting to earn military merit in front of the Demon King, the other members of the Demon King's army also wanted to stay away from Gan Xue, the furious ancestor.
Maybe you think it's a bit pretentious, but the demons in the Demon King's Army don't think so, because they saw with their own eyes that the Demon King's Army, under the leadership of Demon King Ye Feng, unified the five sacred areas, with hundreds of millions of people from all over the world crawling under their feet, conquering the The fourth dimension, fifth dimension, and even conquered more than 80% of the sixth dimension. They are witnesses, participants and co-creators of this kind of thing. Therefore, even if they are not the descendants of the Demon King and have never seen such a great achievement, they will definitely have an almost crazy belief and worship of Ye Feng. This is due to the devil's instinctive and fanatical worship of power. In their eyes, the devil "Ye Feng" is synonymous with power.
The Eighth Route Army set off, and Gan Xue went with only his own troops. In fact, any powerful demon in the Demon King's Army can wipe out the current "primitive" Demon Realm. The reason why they are so slow to do so is not because it will take some time for the Sky Lock to be unsealed. As the saying goes, "It rains." Older children - idleness is also idleness." Find yourself some fun to pass the time.
And just as Gan Xue's army was on its way, the sky in the demon world was suddenly covered with dark clouds, with lightning and thunder. The space in the sky in front and in the distance to the left and right seemed to be broken and torn, and three huge waves of magical pressure came down. Thick clouds of purple, green, and yellow colors emerged from the cracks in the three directions, and countless demons seemed to be moving in the thick clouds.
Gan Xue did not panic, because Gan Xue was no stranger to these three pressures.
