Kill the Ghost with the Sword

"The world is sick, and the root of the disease lies in the human heart!" I, Wei Rong, am a half-citizen and half-bad guy, carrying on my ancestral business from generation to generation as an executioner. Unfortunately, times have changed, beheading has been abolished, and I have lost half of my job in this craft - I can no longer perform "vital organ removal surgery" (excluding loose plates). Times can't be said to have changed for the better - people's hearts have become even worse, and more and more bad people are turning into evil spirits after death. The underworld has recognized my job and sent me to eliminate evil spirits and kill ghosts. To put it bluntly, I am a human being who works for the underworld, a legendary temporary worker with a staff. Recently, it has become popular in the West Village to arrange underworld marriages for young people. I wanted to go and have a look, but something happened when I saw it - it actually involved the god Yue Lao, who is "the eleventh most popular in the heavens". Okay, just go and show your 'loyalty'. As soon as Yue Lao's affairs were settled, another big customer came - the number one God of Wealth. No, why do you big gods like to do things to me, a little shrimp? What? Give me luck? What else can you say! For the sake of the people and the great righteousness, we are duty-bound! "Destroy all evil spirits!" … But later I discovered that the evil ghosts in the world can be killed, but the evil in people's hearts cannot be eradicated. Pride, sloth, greed, gluttony, lust, jealousy, rage... All the problems they cause, When can it be eradicated?
