The things in the world, cause and effect, one after the other, are the law of cause and effect, also known as "fate", but this "fate" is never fixed, but a dynamic state of "fate impermanence", because of this impermanence, the future of the world is changing all the time, so there is a saying that the future is uncertain.

There are so many possibilities for this uncertain and unknown future, including good futures, bad futures, and even more devastating futures.

And the elderly Nobita and others are committed to finding the one with the best ending among the thousands of future branches, and using it as the backbone world line of the star key system.

Originally, this kind of effort has already seen very good results, and the various civilizations in the world have made it possible for Doraemon and Nobita and their friends to form a world civilization alliance in the future, and make the world unprecedentedly united and prosperous.

However, Xu Mo's appearance caused a ripple on the main world line.

"Xu Mo, Xiaoyou, do you know who these conference participants are in front of you?" Nobita, an elderly man projected from a three-dimensional image, asked with a smile.

When Xu Mo heard this, he touched his head and said, "After hearing what you said, it seems that everyone is not just Nobita's friend?" ”

This Nobita is not an elderly Nobita, but the bear child who is being taken care of by Doraemon.

The old Nobita smiled and pointed at the old Rapp: "This is the honorary governor of the Dada civilization, although he has never won the supreme power of the Dada civilization, but because of his many outstanding contributions, he enjoys a high reputation in the Dada civilization, and he is a great man at the level of a great man." ”

He also pointed to a tree man who seemed to be a moving tree: "This is the legendary ambassador of the plant star, Mr. Qibo." ”

Then he pointed to a woman who was no different from a human being, but wore clothes that looked like dragonfly wings on the back: "This is the famous female president of the celestial human race who was once a resident of the earth and later migrated to the aliens, Palpal." ”

"This is ......"

Although Rapp once introduced everyone present, but only introduced the name, but did not specifically introduce his position, when the elderly Nobita completely introduced the glorious identities of the participants to Xu Mo one by one, Xu Mo was surprised to find that there is no one here who is not a legendary figure with great influence in this civilization.

With the completion of the new introduction, the elderly Nobita said slowly: "Although it is a little deliberate, I admit that Nobita and Doraemon know every important friend is not a thing in the pool, and similarly, their experiences are also important historical nodes in this world, although I do not advocate the heroic view of history, and I also think that history is created by everyone, but I can't deny that the influence of these important people on history, when the history they originally experienced was affected......"

The elder Nobita said the next words in a heavy tone: "It will form a turbulence of the causal line, which will then affect the direction of history, and if there is a problem in the direction of history, it will cause a split in the world line, lead the future to another direction, and then affect the stability of the star key system, form chaos at a certain point in time, and become a loophole for some dangerous existences, endangering the security of the entire world." ”

Xu Mo understood a little, and asked in surprise: "You mean, my appearance has affected a certain figure who plays an important role in history?" And there is a change in history, a destabilization of the world line, and then a worldwide crisis? ”

This crime is big enough, he said that his head is too small to wear such a high crime hat!

Fortunately, the old Nobita didn't want to charge him or anything, and sighed: "Of course the problem is not that serious, if there is a problem at one node, it will cause the entire defense system to collapse, isn't the Maginot Line of Defense where the star key system wastes resources in vain?" ”

Xu Mo nodded, this is indeed the truth: "Mr. Nobita, can I ask, which historical figure's causal line I caused the change?" What were the consequences? What do I need to do to make it up? ”

The elderly Nobita pointed at the elderly Rapp: "It's Rapp's sister, Claire." ”

Xu Mo was taken aback, he never thought that it would happen to that cute little girl: "How could it be?" ”

The old Rapp took over the conversation and said to him: "Actually, Claire's experience on the main world line should be that of a famous astronomer of the Dada civilization and the first person to discover the existence of Aragami, but with the connection of the space-time hub to our world, you came into contact with Doraemon, Nobita and other existences that can be called the core of the causal line, and intervened in the Koya Star event that Nobita and they came into contact with us, Claire's life trajectory has changed. ”

Xu Mo asked in surprise, "What change?" ”

"Her plan for the future has changed from an astronomer to an explorer, wanting to participate in the exploration of countless different worlds in the space-time hub, and even wanting to persuade me at that time to go to the space-time hub together and participate in the adventures of the other world." The elderly Rapp did not hide it from him.

Xu Mo said that he understood, but then he felt that it was wrong, since the elderly Rapp still appeared in front of him, and his life experience did not seem to have changed, what about Claire?

As if knowing what he was thinking, the old Rapp continued: "Of course, we have managed to make up for this 'loophole', before Claire left Koya and went to Dada to study, we closed the space-time door connecting Nobita's bedroom to my spaceship, and after discovering that she had lost the passage to the space-time hub, she re-embarked on the path of becoming an astronomer with the persuasion of my mother and me. ”

In this regard, Xu Mo sighed for Claire's disillusionment, but he was still relieved: "In other words, has the problem actually been solved?" Don't scare me, guys. ”

"Yes, the problem is solved, but ......" Old Rapp shook his head, a sad look on his face: "Although Claire has re-become an important historical node, ensuring that our backbone world line has minimized turmoil, she herself is extremely sad, and she has held great regrets all her life, we are sorry for her." ”

Xu Mo wanted to say something, but he didn't know what to say at this time, after all, compared to the safety of the whole world, a girl's personal wish ...... It's too small.

"So, what do you want me to do?" He asked a crucial question.
