This is the mystery of the footprints.
They don't look particularly unusual.
Lin Xiaosu could have accepted that he left no trace in the snow.
But he did leave marks, and they weren't shallow.
Just like a normal person.
However, the unusual part was that every step he took was exceptionally precise.
The gaps were completely consistent.
The distance between his steps was uniform, perhaps achievable by someone who had undergone extremely rigorous training.
But no one could achieve such a level of precision.
Even more inconceivably, the depth of the snow under his feet was completely consistent.
This was on a mountain.
The snow on the mountain varied in thickness, with grass, leaves, mud, and stones underneath, making it impossible for anyone to step on snow with consistent depth, but Lu Yun could.
This old man had intricate ties with Liu Lin Temple.
This old man harbored too many secrets.
Meeting him tonight, Lin Xiaosu hoped to get answers to many questions from him.
