This chapter's epigraph is from a famous poem by Henry Wadsworth Longfellow. Longfellow's poem is about a poison master, a master who poisons those who dare cross his line. In this chapter, the poison master is a guy who eats the flesh of magical beasts. He's also a master at refining his own essence, which is the key to being a great martial artist. This is the guy who ate three pounds of dragon meat, but he hasn't made any progress in refining his essence. This guy is clearly a master of the arts, and he's clearly at the top of his game. He can't even get his essence to break through the meat of a beast. He has to kill the beast to do it.
