Feng Jian's transformation was swift and unsettling. Black veins pulsed beneath his skin, his silver eyes morphing into a malevolent crimson.
The chamber echoed with a grotesque crackling sound, far different from the sharp pops of regular lightning. Dark tendrils of energy snaked from his body, intertwining with the silver lightning, corrupting its once pure form.
"You dare push me this far, boy?" Feng Jian's voice was a guttural rasp, devoid of its former arrogance but laced with a terrifying hunger. "Witness the true power of the Forbidden Lightning!"
The air crackled with an unsettling energy, the oppressive silence shattered by the incessant hiss of the corrupted lightning.
Yun Lintian felt a primal fear clawing at his insides, a warning from his very being. This wasn't just powerful lightning anymore; it was a malevolent force twisted into a weapon of destruction.
