Chu Feng wasn't moving very quickly because he was pondering. At first, he had several plans with which to kill the other party but was almost killed instead. He had completely exposed himself and informed Qin Luoyin that he was alive, so several of his plans were no longer as effective.
He thought the other party would've turned careless after the month of absence, so much so that she might've thought he was dead. But his unexpected appearance might've made her more vigilant.
He suddenly halted his steps and turned back toward the Radiant City of Death. He hadn't even gotten very far before returning.
"I'm sorry, everyone, please let me pick two corpses. Your souls aren't here anyway so the skin is no use to you."
Chu Feng apologized first, then began searching through the battlefield outside of the city. he was picking the weakest human-shaped life forms, but those were fairly rare here.
