Wang Linchi, after reaping the rewards of capturing the Snake Bone Witch and a zombie, naturally returned home with a full load.
Upon his return and further research, he discovered an interesting fact. Although he couldn't control the Snake Bone Witch, he was able to manipulate her through the zombie.
The Snake Bone Witch, who didn't even fear the Three Corpse Brain Worm Pill, was terrified of Wang Linchi threatening her zombie husband.
For instance, when he inspected the zombie's body structure, she was particularly frantic, somewhat resembling a victim witnessing a Minotaur's aggressions.
Thus, Wang Linchi, through the zombie, easily managed to keep the Snake Bone Witch in check.
In doing so, he discovered a new value in this zombie.
If it were any other zombie, Wang Linchi would probably have burnt it after his research because they are essentially useless, possessing at most a corpse-poisoning ability.
