Power Enhancement

The Knight of Marshall secretly rubbed his back with his hand, "Very strong. Abel. That was about 200 pounds of force right there." 

After a long period of body transformation, all of Abel's skin, muscles and bones were now thicker and tighter than ever before. While 200 pound of force might not be a lot, it would hurt a lot more if it was released from an iron rod than if it was from a wooden stick. 

And that's why the Knight of Marshall felt pain back there. Apart from the physical force that Abel used to hit him with, it had something to do with how tough Abel's body was. 

 "You monster," the Knight of Marshall murmured behind Abel's back, "That was just as strong as those giant beasts from the Orc Empire."

"Hit me once more with your combat qi," the Knight of Marshall ordered. Then, as Abel stared at him with a dropped jaw, he grabbed a shield from the corner and placed it in front of him.
