The Void of Endless Darkness
Wo Jin and the Demon King soared through the vast expanse of the starry night sky, their forms mere specks in the infinite blackness.
"Why did you let him go? We've been planning this for so long," the Demon King's voice rumbled, tinged with frustration.
Wo Jin's lips curled into a slight smile. "You wouldn't understand. That person is no simple foe. Though I could not sense any aura from him, he easily managed to destroy a Celestial Grade space treasure - though it was only a low-grade one. He also discerned my presence with ease, putting him on par with myself, at the very least."
The smile on Wo Jin's face grew more sinister. "But do not worry. I have a plan. That disciple of his still carries my treasure within his soul. Though we must push back our plans a little, we will still be able to..."
Suddenly, a muscular, bare-chested figure materialized before the duo, cutting off Wo Jin's words.
