Heroic Embalmer: My Sword Songs Are Charged Per Word

My name is Shen Liu, a low-level undertaker from the Western Wilderness border. In this world where there are more dead than alive, my job is simple: Collect and bury unclaimed bodies. Then save enough money to go to the southern island for retirement. Thousands of years ago, an unfinished sentence of "Cangming Sword Song" caused the continent to sink and everything lost its voice. Today, the powerful are fighting to find the word "sword" that remains on the ancient stone tablet, because it is the only salvation when the end comes. As for me, I just want to live my life peacefully and don't involve myself in it. Until that day, I accidentally swallowed the first sword character - [Ming]. If you don't practice your moves, you don't cultivate your sword energy. He opens his mouth and shoots out, instantly killing everything. I thought it was a miracle, but actually it was a curse. Because every syllable brings me as much pain as swallowing broken glass. Others cost money to sing, but I cost my life to sing. As the word "Ming" entered my stomach, those "things" sleeping underground woke up. The crazy and out-of-control heroic spirits, the sword tomb buried underground for a long time... They all seemed to have heard my call. I could only cover my bleeding neck and finish singing this mourning song for the gods under the fearful eyes of a group of gods and demons. This is the story of a money-mad man who is afraid of pain and is forced to use a thirty-six-character ancient proverb to chop down an era.
