Chapter 666: Another Cave Heaven

Han Fei and Lina were already walking on this dim staircase. They didn't know how deep they were underground. From just now to now, Han Fei and the others had already descended about seven or eight floors. But this still hasn't reached the real bottom, and Han Fei even has some thoughts of retreating. It's so deep here. If you encounter any danger later, you may be locked here.
