What could be the plot of a 'naruto e erza spirit fanfic'?

Deep in the woods at the border of Land of Fire, there could be found a hidden village with advance technology, powerful villagers and an immortal leader. Tanaka was reincarnated in the world of Shinobi, A world full of dangers and ninja, he had received a village from his system in which he needed to expand and become the strongest hidden village in the whole Shinobi World. -LazyTanaka Hey, im just trying this out and im not sure if this ff could last up to 60 chapters since my story pacing is very fast and I changed the Naruto story line but I will try to keep it good as possible.

A typical man on his teens who had lived a harsh life dies in the hands of Truck-kun(?) and was transported to a random God who gave him a chance to be reincarnated in another world. He was given a chance to grant five of his wishes and was reincarnated...in a random(?) anime world where he was a [Spirit] accompanied with some... unnecessary perks like the ability to travel through other worlds albeit randomly and a [Fragment]. And when he landed on his first world, he was not reincarnated as a normal [Spirit] mainly because of that...[Fragment], he was shifted into an [Inverse Spirit]. A being described in that world to be the embodiment of disasters, ruin, and chaos. How would his endeavors turn out to be in this new life of his? Would he be even successful on his journey? Would he even 'fix' himself in the process? Or would he even travel worlds on the first place? Who knows, come read and find out.

I promise ya, the later chaps would be worth reading and investing your time on Chapter Update Release: Yeah bruh... I don't have any stable update time so meh. This is also my first fan-fic so please go easy on me hehe (≧▽≦) [Edit: 5/19/22- The beginning two arcs is totally rough. As in, yeah. The story was still in its testing point back then, so it is inevitable... But right now, I think it's worth reading starting at the third arc, the MC is still not the best but is now clearly showing some development. ;)]

When I died I didn't expect to wake up with dark beings of immeasurable power looming over me. I didn't expect to be given new life in a brand new world. Now, armed with a powerful system that makes me stronger after every fight, I might be the last thing standing between the multiverse and absolute annihilation. As I complete quests, defeat foes and become stronger, I still don't know if I'll be able to save this world, my old world and all the worlds in between. "And below... the MAW beckoned..."

This is a Naruto/Naruto Shippuden/Boruto fanfic. It is possible that the MC might venture into other worlds but that depends on how everything goes. By the way, this novel will feature a system but before you start rioting, this system will not feature any bloodlines or summonings or anything like that. It's gonna be from one particular series, and the series in itself is going to be weaker than naruto so don't expect an OP mc from the start. There's gonna be a lot of training too.

Life is unexpected after all. Unexpected and mysterious. You never know what could happen. Even so people have certain expectations. Things in the line of reality. Things that could actually happen.

What isn't in that line is waking up in a forest in the middle of nowhere with short term memory loss. Even more impossible is finding out that you went from 15 years old to 5 years old. The impossibilities keep on going. Not only did she wake up in a forest, find out she was five and suffered from short term memory loss,she somehow stumbled upon the gate to the leaf village. The line of reality had completely shattered
