Review Detail of 14thLetterN in Asura Conqueror System

This novel is one of the most well written novel I've came across in recent time,the world building even though small is wonderful and it'll surely expand in upcoming chapters,the mc is good even though a little Cruel and understandably so but he is still likeable, the cultivation system is also unique and well thought out and the whole asura conqueror theme gives it an exciting turn,but I wanted to ask that it's an original series or a translation.
