BECOMING AN IRREGULAR WITH A ROGUE SYSTEM

I'M STARTING THE REWRITING OF THE STORY
(I'm still working on the system's basics, but one thing I can tell y'all for sure.
Once the new version is released, the first 195 chapters will be free for y'all to read, as a form of compensating all of you loyal readers who have been hanging on with me through this fiasco - and I'm sorry to those who actually liked it, but it's no lie that BAIWARS flopped - so yeah, next time, first 195 chapters will be free, and you'll see the experience I gathered taking shape into something AWESOME!)
*START READING FROM AUX. VOLUME*
After a cataclysmic event called The Great Calamity, strange rifts began opening all around the world, giving entrance to places we never saw before, full of monstrous beings.
We call them Nests.


The world, then, gave birth to people with special abilities. Powers that allowed them to fight the beasts inside the Nests.

Those who chose to raid the Nests and fight for mankind were called Wielders, and little by little, society came to get used to the perspective that magic had become an innate part of their lives.

Kurt Blake is a regular.
An unawakened human being.

After an act of treason, he dies, but is granted a system upon death, that makes him regress in time to his sixteens, in order for him to rewrite his own history, and take revenge upon his family.

What he doesn't know, is that this system is just a single fragment of something more powerful.
Something wicked.

Something that wants him dead to feed on his newly found powers.

But is it the only secret the system holds from Kurt?

Are the Nests simply rifts to another dimensions full of monsters?

Or is the MC living just a part from a whole story that he's not aware of (yet)?
