Following the mission's requirement to keep the captive alive, Duan Tie stripped the prisoner completely, though only referring to his clothes. Then he used his Blood Blade to carve talismans all over the man's body—talismans used in interrogations by the Divine Sect—to trap the soul within the shell, ensuring the person couldn't die, or if dead, the soul wouldn't scatter.

Thus, Chen Xuantian took extra steps by prying out all his teeth, preventing the man from committing suicide with some poison hidden in the molars as in the movies.
