Zhang Chi handed over the last letter from King Jin Li to Wenren Li in the secret realm.
It could help her understand the entire cause and effect of the events, and could also be seen as information sharing.
At this stage, Zhang Chi and Wenren Li were constantly exchanging glances, engaging in silent communication.
Gu Youyou didn't understand it at the time and was baffled now.
She had been with Zhang Chi all the time. When Zhang Chi was awake, so was she; when Zhang Chi was asleep, she was still awake.
She was always standby throughout.
But she never realized when Zhang Chi completed the commission with Wenren Li and what the commission was.
"Are you now able to keep things from me to my face?"
Zhang Chi had only restricted part of Gu Youyou's mind-reading towards him. Most of the time, she still knew what he was thinking.
