Being Unemployed, I Really Couldn't Do Anything to Become a Demon Slayer.

My life so far has been marked by failure, and I have struggled to escape it. As I continued to endlessly prepare for the written examination, a beautiful girl suddenly fell from the sky! The beauty coaxed and deceived me to lead me to another unknown road. Join the fight between humans and demons! I don't know when some extremely powerful mysterious existence was lodged in my body. Super high talent, level 7 genius, and the mysterious existence in my body promises that I will become the strongest human being! From now on, the word mediocrity has nothing to do with me anymore, I will be the new star of the entire human race! But as my involvement deepened, I found that the matter was not that simple... The beautiful girl who descended from the sky and the powerful existence within her body seemed to have some strong purpose for me... Even the origin of the battle between humans and demons becomes more and more bizarre as I dig deeper... The water became deeper and deeper, and the facts became more and more bizarre. I was deeply involved, and finally I discovered that my life experience was surprisingly closely related to this protracted battle! Wanjia Denghuang still lives in a peaceful and prosperous age, and ordinary people do not know the existence of demons at all. But I could no longer live a peaceful life. Being in the center of the dark vortex, I found that everyone on both sides seemed to be coveting me. But this time, I will take control of my own destiny and end it all!
