"Fong Yixiu, of everyone present, only you are proficient in Qimen Strang Arts. Tell us, how did Xiao Yao manage to enter Renli Hospital?" Xuanyuan Shitian suddenly asked.
Fong Yixiu furrowed his brow slightly and said indifferently, "Invisibility Formation!"
At the mention of the invisibility formation, everyone in the hall was startled once again. However, this time it was because they had received an answer.
This explained everything.
But...
"However, the invisibility formation only works on a localized area and cannot be cast upon a person." Fong Yixiu's remark was like dropping a bomb. This meant that unless Xiao Yao had set up an invisibility formation over the entire hospital, she couldn't have become invisible.
This meant that Xiao Yao hadn't sneaked into Chang Haotian's ward using the invisibility formation at all.
For a moment, this confusion seemed to hit a deadlock.
