Collapsing World: I have become the main body of idiot Na!

PS: It’s just a fan, don’t bring in official settings and games

one thing i don't understand
I worked so hard and persisted
But it turned out to be of no avail
I hate losing everything I have

But still to no avail
Maybe, in the end, I'll be born again
However, is the price of embarking on this path too heavy?
