If, suddenly one day, you meet an unknown creature claiming to be someone on the way, don't be too busy drooling, because this is not time travel; and don't worry that your wealth and life will be threatened, I'm sorry that we are not the savior.
A life surrounded by a group of unknown creatures all day long may not necessarily lead to happiness, because they are not Doraemon. When they only cause trouble for you and shamelessly use a lot of vulgar excuses to stall you, remember to pack them all and send them to the exhibition hall. It is more practical to make more money.
Part one
Mending the Sky
--------------------------------------------------
The heroine's rules for safe survival: don't randomly pick up puppies and kittens and other alien creatures on the roadside; don't run towards empty and uninhabited places, the weirder they are; don't walk through the water idly, don't mess around with women, don't touch dangerous things on the roadside; don't walk on the road, don't walk on the road, don't go to the toilet, don't sleep...
If you can do the above, congratulations, you have become an immortal!
