"Sage" is the name of the old man in front of him by those who know about this world, because his arrival has avoided a catastrophe of destruction in this world, promoted the development of this world to an incomparable height in a relatively short period of time, and brought precious security and peace, kindness and hope to this world. Pen, fun, and www.biquge.info

He is a true hero, even in the last twilight of his life, he still suppresses the luck of this world and maintains the harmonious operation of this world.

"I'm doing well, thank you Xu Mo Xiaoyou for your concern," the old Nobita was as always, kind and kind: "But now, there are some small issues related to Xiaoyou, and I need to negotiate with Xiaoyou." ”

Xu Mo was also a second monk who was puzzled: "You said, I'm also confused now, I was invited here, but these friends played dumb riddles to me one by one, and didn't tell me what happened, which made me very painful." ”

"Hahahaha, Xiaoyou is really interesting." The old Nobita laughed happily for a while, and then said: "But this matter is indeed a bit complicated, and it is my own hand, when I encounter problems, they are embarrassed, and it is also reasonable, since I have found me, I will rely on the old and sell the old, and make an explanation." ”

Just said something, but it was earth-shattering, and Xu Mo was startled.

He affected the main world line of this world, causing a certain deviation in the originally stable main world line, affecting the stability of the entire existing world system.

This is a long story, but it is to trace back to the old Nobita after he came to this world, in order to prevent this world from going down the same path as his hometown, and agreed on a great goal with many like-minded people, this goal is to make people live happily and contentedly, to unite the world, to form an organic and unified whole, to avoid excessive internal friction, and to avoid fighting separately in the face of external enemies.

In order to achieve this goal, Nobita set out to form institutions that transcend political entities, such as the Time and Space Administration and the World Management Agency, and began a journey of unification of this world.

The unification of the world is not simply the unification of the regime, because in the face of many super invaders, the other side does not need to face your army, fleet or anything at all, it may throw you a two-way foil, and the entire galaxy will become a piece of paper, or it may dive into the timeline and destroy the entire civilization directly from the source of your birth, or through mind control, you will kill each other.

Therefore, if you want to complete the integration of the world, the most important thing is the formation of the star key system, Xu Mo only knew at this time that the formation of the star key system is not simply a system made up of various devices, but something more complex.

Using various equipment to stabilize material particles and maintain spatial stability is just the most basic protection, and it is frenzied to go up to the higher levels of time protection measures, causality protection measures, etc., and these involve the composition of the main world line, which is a rather tricky and delicate job, and it is not possible to do it.

Because there are too many forks in the long river of time, which leads to thousands of branches in the world line, if you are not sure of a backbone, then, the star key system will be established without positioning, and the lack of positioning of the star key system is simply a sieve full of loopholes, for example, if someone uses a phone booth, goes to a branch world line, and then wants to go back, because there is no accurate positioning, the result is lost in other world lines, he may never be able to return to the real world line, and he will disappear, Such a chaotic world line is certainly not in line with the Star Key System's control over all world elements.

And determining the backbone world line is a very important matter, because once the backbone world line is determined, it will become the stabilizer of the star key system, and it will also be the weakness of the star key system, if there is an enemy who destroys its stability, it is likely to cause a hole in the entire world defense line.

However, the determination of the backbone world line still involves many issues, involving the history that has happened, the reality that is happening, the direction of future history, and many other tricky time correction issues, and also taking into account the billion-trillion-level causal fate development link, if one is not careful, it is likely that the future will go to a very bad end, and then it will be over.

Therefore, in order to lead to a better future and have a stable backbone world line, the elderly Nobita and countless comrades have worked hard to finally formulate a plan, a "perfect node" plan.

The composition of the world line is very complex, and the relationship between time and cause and effect is extremely complex, but if some important nodes can be guaranteed to be unshaken, even if there is a problem in the interval between the nodes and there is a certain distortion, it can also produce a strong inertia due to the interconnection between the nodes, pull the error back on track, or give a buffer for correction agencies such as the Time Management Bureau to solve the problem.

So, after discussing with the elderly Nobita and his comrades, it was decided to carry out the "artificial setting" of the nodes, that is, to create history.

There must be people to make history, and in the process, we must go as far as possible to the line of world unity, and we must connect with other civilizations in the world to move towards a better future.

It just so happened that at this time, the elderly Nobita discovered Nobita, and he found Nobita carved out of almost the same mold as himself, and this Nobita is really talented, he can be called a good old man, and the elementary school period is the most innocent season of his heart, if he is the stabilizer of this historical node......

So, in the eyes of Nobi Seshu, it was the elderly Nobita who tried to change the fate of his grandfather Nobita for the sake of kinship, but in fact, everything was already in the arrangement of the old Nobita and others.

The seemingly flawed Doraemon appeared next to Nobita, and Nobita and his friends began many unbelievable adventures, forming good friends with many people, and spreading human friendship to many corners of this world......

In order to achieve their goals, the elderly Nobita and others even kept Nobita the same age through time misalignment, adjustment, and mental misdirection, and kept all kinds of adventures and friendship diffusion activities, so that his elementary school went endlessly, but no one felt wrong.

In the end, Doraemon and Nobita and others became an important causal core for the various civilizations in this world to unite together, and it was because of their adventures and acquaintances with many civilizations that the world was able to finally form a unified alliance of civilizations and develop to such a state, which is the meticulous work of the elderly Nobita and many people!

However, the agitation of Xu Mo, an outsider, caused one of the causal lines to deviate, and then shook the entire backbone world line.
