Song Yan also wanted to know how Yun Zhao could be possessed when he was carrying her talisman. Other than the talisman losing its effect there was only one other reason and that was —— the talisman that Yun Zhao was carrying wasn't hers!
She said to Yun Zhao, "Take the talisman out, I need to check if it is running low on spiritual power." Though she had some suspicion, she did not speak out loud.
Song Yan first needed to confirm that her suspicions were correct or not before jumping to conclusions.
Yun Zhao did not suspect anything. He nodded and took out the talisman that he was carrying with him.
He handed it to Song Yan who took the talisman in her hands and carefully looked at it. She turned it front to back, before parting her red lips, "This is not the talisman that I gave you. It's fake."
