When the Second Generation Nether King dispatched seventeen personal guards with the Hand of Death to the mortal world, he demarcated seventeen large prisons within the Eighteen Levels of Hell to receive the Yin Souls sent by the Hand of Death. The Yin Souls delivered by the same Hand of Death were confined in the same prison.
Therefore, it was not difficult for Zhao Chong to find Xie Xiaofeng and Tang Jing; he simply had to search through each of the seventeen prisons one by one.
Furthermore, ever since the Ghost King took control of the Netherworld eighteen years ago, the Eighteen Levels of Hell had been left unguarded, so over the years, the Yin Souls brought by the Hand of Death had been left unattended.
For this reason, the Yin Souls of the Yang Family Village villagers sent to the Eighteen Levels of Hell during the past twelve years should still be in the same prison as Xie Xiaofeng and Tang Jing's Yin Souls.
