The moment Su Yubing put her hand on the sword hilt and gave it just a slight tug, it actually came out from the black stone wall!
Not only that, but the moment the sword hilt came out, the place on the black stone wall where the sword hilt was inserted in actually started crumbling down like dust and ashes and it didn't stop until the whole section on the side of this black stone wall turned into ashes that Mo Yuxin and Su Yubing could finally pay attention to the sword in their hand.
But what surprised them most isn't the fact that Su Yubing could pull the sword out of the seemingly tough black stone wall while Mo Yuxin couldn't or that the black stone wall which seemed tougher and stronger than normal rocks by many times actually turned into fine dust just like that, it's the fact that the sword which they thought was a sword turned out to be broken sword!!
