I Kill All Evil Spirits

This is a world full of evil rumors! Zhang Yu traveled through time, but found that he had become a death row prisoner taking the blame. Time travel means beheading? Don't. Fortunately, I discovered that I could absorb souls and drop fragments. Fragments of warriors' martial arts, fragments of cultivators' techniques, and even fragments of memories. Bring them all! As for evil spirits? Then let me absorb some evil energy and help me make further progress in my cultivation. Sorry, I seem to be the most evil one.
