As they continued to walk inside, Feng Jiu's speed increased, which made it difficult for Wang Yu who was following behind, to keep up. Leng Shuang was able to keep up, but Wang Yu was about three metres behind. This was him using his spirit energy to be able to follow them closely. Once he relaxed a little, the distance between them widened again.
The two people in front walked ahead lightly, and after a whole morning, the distance between them went from three metres to five metres.
Leng Shuang glanced back and saw that Wang Yu was struggling to keep up with them. The edges of his clothes were stained with mud and his boots were covered in mud. Sweat dripped from his forehead as he panted.
