Lou Yi ran a hard wooden stick across the surface of his palm, feeling almost no pain.
Next, he took out a saber.
First, he tried it forcefully with the back of the blade; his skin felt itchy on the surface, but it remained unharmed. He gradually increased the force, but it couldn't penetrate.
Then, he lightly slashed with the sharp edge, leaving not a scratch.
He increased the force little by little until at fifty percent strength, his palm finally started to break the skin.
Lou Yi wasn't a masochist, but to test the limits of this ability, he really needed to attempt it with the sharp edge.
Doing so would enable him to have a more precise control over weapon combat in the future.
With his current strength, fifty percent force still carried the weight of one thousand catties.
In other words, an ordinary person, even wielding a weapon, would not be able to cause him any harm once his skin had petrified.
