I'm Nightingale (1)

"How did it go?"

Xu Xiaoshou couldn't help but ask after a quarter of an hour and saw that Xiao Kongtong had a layer of sweat on his face.

"Big! It's too big!"

Xiao Kongtong turned around, but he did not retract his sword. Instead, he sent out a wisp of his spiritual senses in response.

"The interior of the First Hall of Sins is a little bigger than I thought. I've used the Ten Thousand Sword Technique to do a rapid search and calculated all the possible results, but I still haven't found a regular answer." 

"After all, this is the most difficult way to solve the problem." Xu Xiaoshou muttered.

Since he was the Eldest Senior Brother of the Fringe Moon Immortal City, there was no need to doubt Xiao Kongtong's strength.

Xu Xiaoshou estimated that in the duration of half an hour, Xiao Kongtong had probably used his small Void Stilettos to explore an area that was almost half the size of the Forest of Miracles.
