This causes trouble for my employees because cultivators tend to behave unpredictably. The strongest few even require me to intervene personally. That is why the penalty costs are different," the Lord of Death explained.
Wei Chen could not help but imagine a scene of overworked Underworld immigration officers standing at inspection lines filled with mortal souls, while cultivators with a bit of strength caused commotion and fought with the security staff.
