The pain this time was multiplied several times compared to before. He was now powerless to resist, and cold sweat dripped down his forehead. Struggling to hold himself up, he fell to his knees in the void, not daring to say another word, and repeatedly begged Gu Lan for mercy.
"Please, senior, show mercy!"
He wasn't afraid of death, but he couldn't bear the terrifying torment inflicted by Gu Lan. Rather than continue like this, it would be better to put an end to it. But Gu Lan had no intention of showing mercy. Upon hearing his voice, Gu Lan showed a faint smile.
"It's not impossible. Follow me for a thousand years, and after that, I'll return your freedom."
He had no other choice now. In comparison to what Gu Lan had said, he could only nod in agreement.
"I am willing to obey your arrangements, master."
Gu Lan was pleased with his compliance, smiling faintly and nodding before he stopped hesitating and withdrew his aura. The intense pain in Shadow Slave's body began to ease.
