After an unknown amount of time meditating, Nian Bing was suddenly awoken by a knock on the door. His spiritual power immediately stopped gathering mana from the outside world and he awakened.
"Who is it?" At this time, it was already the deep night and a fog filled the air outside the window. Nian Bing got up, first closing the curtains, and then went to the door.
"Open up, it's me." A beautiful and pleasing voice rang out from outside, and Nian Bing was surprised to realize it was Feng Nu who was visiting.
He opened the door to find Feng Nu standing in the doorway, giving him a lovely smile.
"What brought you here this late?" Nian Bing asked in surprise.
Feng Nu smiled and replied, "So, are you not going to invite me in?"
Nian Bing laughed bitterly, "Isn't it unnecessary? It's quite late, and what's a young lady like you doing in my room at such an hour?"
