If it's about asking fixed questions, it might still just be the answers of an intelligent robot.
But if you ask about events from the past, only known to the two of them, then the truth can be discerned.
As it was inconvenient to answer calls by the dining table, Luo Yang stepped outside.
After connecting, he asked, "I'm outside. Just wanted to check if you need me to buy anything for you, like a quilt or something."
Sure enough, Zhang Jing's voice came from the other end!
"Master, no need."

Back then, Zhang Jing had sought to learn Shadow Fist from Luo Yang, and he had agreed to teach her.
"Say it again, which skill do you want to learn from me? I'll teach it to you as soon as we're back." Luo Yang said.
"Master, I want to learn Shadow Fist!" Zhang Jing's voice was excited.
Whoa!
If this isn't Zhang Jing, then who could it be?
