Shit-bucket?
Feng Yin didn't have that realization at all.
Rather, he completely ignored the Illusory Silkworm's intentions, channeling all of his spirit, all of his energy into incessant nagging.
"Isn't it just lending a hand, a little help to save someone? For you, it's nothing more than lifting a finger, yet you refuse to help. Not only do you refuse to help, you even chase after me to kill me... What kind of behavior is this? Returning kindness with ingratitude, paying good with evil, utterly insane and outrageous..."
"What haven't I given you? I've given almost everything I have, made every sacrifice... and in return, I get hunted and robbed. This is truly..."
"Thankless and shameless, despicably low and nasty to the extreme!"
"How could this happen!"
"The Illusory Silkworm is also a top-notch fighter, how can it be so heartless!"
