He was originally a barefoot doctor that no one cared about in the mountains. A silver needle could reverse life and death and break the cycle of reincarnation. When he first entered the city, he was ridiculed as a country bumpkin, but he rescued a top rich man who suffered cardiac arrest in full public view. Western medicine experts knelt down to pray, and powerful people lined up to send money, but he just wanted to live quietly. Trouble ensued. When the killer strikes late at night, his silver needle shoots through the air and sweeps across the entire scene alone. The whole city was shaken, and countless big guys joined forces to encircle and suppress him. He sneered and wiped out the enemy with a snap of his fingers. Since you can't hide your edge, you will look down upon the whole city.
