First of all: energy, a concept that is not present in this country...... Because they have metal "clouds" and metal "fogs......

Then there is communication and networking, and almost every citizen over the age of four who is slightly sensible will have a hand-held system... He is at least 100 million times more advanced than the computers and telephones of our earth...... The principle of their communication is... We can't at least say that right now... However, you can use an analogy, for example, if you use your fingers to turn the chopsticks at one end of it, then the other end of the chopstick will also rotate, and it will rotate at the same time...... Therefore, as long as these aliens have been to the place, they don't need time to call home, even if the farthest flying unmanned spacecraft (there were people on it at the beginning, but then died), the distance between the Summit, and the distance between the Summit, is 4 billion light years away, and it will not take time (even if they do, it will only take a few minutes)......

Even if one of them is one, the cute and upper-middle-level robots (such as the Wu Hook Cannon hidden in the nails of the Roaring Sky) are for us earthlings.

And then it gradually increases until the ninth year, the whole nine years, which is equivalent to about ten days for them. Then the life outside the cave reaches the tenth year, which will not only be equivalent to their day and two days (it may not be superimposed, but ten to the nth power), but equivalent to their 100 years, and the Heavenly Court people will die of old age quickly in this year... Doom to come...... And if they don't go out of the cave for the rest of their lives, they will live to seventy-eight or nine, and if they are young, they will go out of the cave for eight years, and they will die at the age of seventy... Most of the people chose to go out of the cave and explore when they were young......
