Song Jian stepped into the Sword Spirit Pool, and immediately his external perception was compressed to its limit; he could only sense an area less than a meter around him. He had encountered this situation more than once before, so Song Jian was not panicked, but because the fog was thick and he was far from Xin Ling, he could no longer sense her presence. It was as if in this vast expanse of white, he was the only person.
Indeed, the Sword Spirit Pool was an empty basin, with hard stone slabs underfoot and mist flowing around. Bit by bit, it continuously invaded Song Jian's body, making him feel cool and refreshed all over.
Looking at the dense white fog around him, Song Jian did not feel any improvement in his strength, neither in skill proficiency nor in level experience; everything remained still.
