And now, this blade was even sharper than before, but when used with force, it still did not cut through the skin on his arm.
"Turns out my skin has really become this tough—this must be what they call impervious to swords and spears!" Jiang Ning exclaimed, looking at the white mark on his own arm.
At this moment, his understanding of the transformation after bone forging deepened.
Clearly, the toughness of his skin was related to stepping into the Bone Forging Realm.
Having succeeded in bone forging, creating iron bones, one's body undergoes a complete transformation.
Muscles, membranes, and the epidermis all became tougher.
Next,
he held a spiritual weapon in his left hand and applied more strength.
With his forceful slash, a five-centimeter long wound appeared on his right arm.
But with this cut, only a faint trace of blood emerged; the wound was clearly not deep.
"Such tough membranes!" Jiang Ning marveled again.
