Hui Kui glanced at his reflection in a nearby puddle, shocked at the transformation. "I... I look incredible!"
Caleb shrugged, feigning nonchalance. "Well, why not? A little fitness boost never hurt anyone."
The newly transformed Hui Kui bowed respectfully. "Master, thank you for this... improvement. I am yours to command."
In an instant, Hui Kui's body transformed. His appearance remained, but he now sported a much more athletic and handsome physique. He blinked, looking at his own hands in disbelief.
"Huh? What did you do? M-master..." Hui Kui asked, bewildered but seemingly unharmed.
Caleb grinned, reveling in his experiment's success. "Now that's more like it, Hui Kui. Welcome to the upgraded version of yourself."
Caleb chuckled, "Just a little adjustment, my new servant. You're still you, just with a bonus upgrade. Instead of fusing you to them. I fused them to you. Neat, isn't it?"
