He was originally a man of few words and wanted to explain but didn't know how.
After a while, he felt it was inappropriate to try explaining again, so he changed the subject instead.
"Xiaowei brother, how long will this take?"
"At least half an hour, be patient," Zhang Xiaowei replied offhandedly, pulling out his phone to play with.
