Start with the Mass Graves

My name is Chen Jin, the buryer of the mass grave. Without spiritual roots, he was born to be a mortal who could only do one thing every day: dig holes, bury corpses, get a few copper coins, and live. When they killed me, they said that mortals should just accept their fate. But I don't know what I am. Don't know why it came to life. I don't know what those things are in my body. I only know one thing - Whoever wants me to die, I will let him die first.
