In everyone's opinion, Stephen was just dying because of his severe injuries, but Lin Li knew clearly that the sword that had condensed and formed in the Light and Darkness Domain had not only cut off Stephen's Soul-devouring Domain, but also ended his life. Hence, Stephen could be considered no different from dead now. Even with Mephistos's peculiarly strong power, he could never be reborn using Stephen's body.
Lin Li could tell that if he insisted on keeping Stephen, Borg would never hesitate to give up his life to take Stephen back. Although he needed not be afraid of the Dark Blade's two Legendary leaders now that he had the help of Cheyenne who would complement his abilities, he felt that he would be going against his own interests by fighting and going against a Legendary powerhouse for the sake of a dead person.
While Borg was watching, Lin Li nodded, and said, "Alright, you may take him away."
