"Hello, my name is Nobita Nobi. I'm an adventurer wandering between multiverses, and I save the world simply because I enjoy it."
"This is a warning with prophetic implications! If you've received this message, please pay attention. Wherever you are, your world has already undergone, is undergoing, or is about to undergo unusual changes, and these changes will inevitably bring consequences. It could be the ruin of the everyday lives of three or five people, or the upheaval of the entire world... It depends on the circumstances. If your world hasn't changed yet, we recommend that you prepare in every way you can, just in case. If your world has already begun to change in all sorts of ways, don't worry."
The boy on the screen was surrounded by darkness, standing alone beneath a fringe of lamplight, his gaze sharp as lightning.
He looked ahead like a captain standing aboard a ship tossed by wind and rain, surveying a turbulent and treacherous sea.
"Because we've already set out."
"We'll be at your doorstep soon."
P.S. The previous work was The Wonderful Adventures of Nobita in Another World. It wasn't very popular, but you should be able to find it on Baidu. Feel free to check it out if you're interested.
