Calamity of Tomorrow - Chapter 404 - 403 50 years

A medical student died because of negligence of the authorities. Later, he is granted a second chance in life with some boons. But being an Otaku and Naruto fan, he chooses to live in the chaotic world of Naruto.

The story will follow canon for the initial part with a new plot. Major changes will reflect in the later part as our MC grows up. The story has strong AU elements and the power scaling is ramped up to explore various foreign elements in Naruto. Everything in its entirety will be a part of the Naruto series with details and speculations of my own.

This story is my original creation, and I post it on Scribble hub and Webnovel. You might find a few initial chapters on Royal Road.

Note:- The starting 40 chapters or so have poor grammar and various mistakes since I was a new writer back then and lacked experience. But I am working on editing them.

Warning:-I don't own Naruto or any related stuff except my MC and Original characters and jutsus. (Yep, there are lots and lots of original jutsus in the story.)

Play it well.In a realm where betrayal is currency and power is the only law, William does not resist fate—he embraces it. Every alliance is a move on the board. Every rival, a piece to be sacrificed. Every betrayal, already foreseen.But even a villain is not invincible. Enemies rise. Shadows scheme. And the system watches, amused—waiting to see if he will fall...Or if he will burn the world to prove that even fate can be rewritten.But one question remains:“Who summoned him… and what do they want in return?”--------------------------------AUTHOR HEREWilliam Medici starts off seeming wholesome—but don’t be deceived.
