Death's Promise

I came across this book again out of nowhere, and I remembered that I liked it very much at first. Unfortunately, it was said that it was published, and then there was no more content. I couldn't find the physical book, and the online version is just like this. It's a pity.

Does anyone know the content of the final chapter of Death's Promise?

I have read a pirated copy of the book at the end. I remember the final fight with Randy. Randy wanted to recruit him, but the protagonist has the blood of the former Death. His mother is the sister of the previous Death. In the end, he defeated Randy and became the new Death.
