The ability "Substitute by Death," Leyu had only triggered it once so far.
After all, the activation conditions of this skill were insanely strict. "There's nothing scarier than being on the edge of life and death." The first time, Leyu had successfully crossed over from his original body into Qian Yuliu's, but what about next time? "Will the skill fail to activate? Will there be other hidden requirements? Are there any side effects? Is there a limit to the number of uses?"
Because the activation condition was death, Leyu didn't dare to test it at will. "A normal human's basic instinct is to survive—who would deliberately seek death? This skill itself goes against every human impulse."
And "Substitute by Death" stated clearly that Leyu could only cross into the body of his killer. Without any other examples, Leyu had no choice but to trust the skill description.
Which meant, with no killer, or in cases like suicide, illness, or dying of old age, Leyu would truly be dead for good.
