Emperor Feng Du pondered deeply for a moment and suddenly understood.
The Mountain River Sheji Map was a treasure by which Miss Nuwa proved her Dao, so it definitely held some enlightenment left by Miss Nuwa. With Mianmian being chosen by the Heavenly Dao, after she entered the Mountain River Sheji Map, it merged Miss Nuwa's warnings with the Little World inside, allowing Mianmian to gain experience in advance. It was highly possible.
Emperor Feng Du, feeling curious, asked, "Then how did you defeat the Heavenly Demon inside the Mountain River Sheji Map?"
This question immediately brought Atian to Mianmian's mind.
