Hello there,
Now, I am rather pleased to announce that I have to write approximately 20 chapters, max 25 chapters, to finish this story. That would put the overall chapter count to 725 +/-.
Afterwards, I will be doing an entirely new book that would showcase the conclusion of the entire Saga.
It would be titled Holy Chronicles of the Baator: The 4th Singularity and would cover the second part of the Warhammer 40k, some aftermaths and so on. It would be written in 5k chapter formats from the 3rd-POV and focus more on other characters than the MC.
By the end of HCB, he would basically be so OP that it would be boring to write and read about it that much... as in the entire Reality, you won't find that many people that are at his level, much less speak about a threat to him.
