Terrifying changes

A dense red star energy gushed out, flooding Klaus's soul sea with an overwhelming and terrifying power. Outside his body, small runes began revolving around him, while his aura surged higher by the second. Inside his body, his bones started glowing golden as ancient runes lit up along them.

"How is this possible?" the Senior muttered, wide-eyed as he observed the changes.

"Senior, what's happening?" Klaus asked, feeling his strength soar and his Star Qi rising to unfathomable levels.

"You've merged with the star energy," the Senior replied, "and now it's reforming your bones."

"Reforming? Does that mean I'm getting new bones?" Klaus questioned, but the Senior remained silent. Klaus quickly realized the answer for himself. He could feel it—deep within his body, his arm bones were turning transparent. As more energy flooded in, the rest of his bones began to shift, becoming clearer with every second.
