Do you go door to door to ask if your child is interested in funerals?
Your child is a rare funeral genius in a century. Will you come with me to send light to the people in another world?
It's not easy.
Lu Changsheng just received his apprentices, but those apprentices made him worry more and more...
"You said your apprentice is the first person in the human race, the chief of the Demon Slayer Division?"
Lu Changsheng nodded.
"You also said that your disciple is the famous Guan family saint? He once single-handedly defeated the demon clan for thousands of miles, and the beasts he killed were afraid of the word Guan?"

Lu Changsheng still nodded.

Lu Changsheng said helplessly, "This story is a long story..."
