Record of a Demon’s Cultivation

What's the book about? It is about Demonic Cultivation!, If you cannot handle it, Please don't read it. The side characters aren't stupid, instead they are crazy and ruthless, not easy to deal with. Read at least 80 Chapters before deciding.

Synopsis:
When Song Wen killed the frail beggar who fought him over food and consumed his blood and soul, every cell in his body leaped with excitement. His spirit was exhilarated, and he realized then that his life would henceforth be filled with slaughter. For survival, for longevity, he would spare no effort, even if it meant creating mountains of corpses and seas of blood.

Translator's Review:
Translator Here! Since this is not my own creation I can be somewhat objective about it.
The story starts out slow, and even a little boring but it starts to grow on you after 80 or so chapters. The characters aren't your average 2D characters that you see in any other novel. They have depth and are not easy to deal with.
MC is neither naïve, nor a saint. he is ruthless when he needs to be. He is cautious and doesn't take unnecessary risks.
There isn't a harem, nor any hints of it so far (880 Chapters).
So please give it a go and let me know what you think of this story...
