The lightless cube is a special spatial treasure. It can definitely save one's life but it has a big drawback
The user's body can enter the cube, it was a treasure that can perfectly keep a living person. It has its own space inside
The problem was that, as its name implies, the cube was completely devoid of light
Being inside it would make people lose their sense of sight. In fact, that wasn't all
The lightless cube would also deprive the person inside all of their senses, not just sight
This treasure can be used to hide since the cube can be manipulated to be as small as a grain of sand but it also has a great risk
To be deprived of all senses, just how awful would that be? Not everyone can endure such an experience
Out of the three, only Khaknur has so much fear for his life. Despite the great drawback of the lightless cube, Rhash still gave it to him
