The Hundred Ghosts Grand Review is akin to a court assembly among Yin Spirits.
In another world before Chu Xisheng 'crossed over', there was also a Hundred Ghosts Grand Review.
Zhang Heng of the Eastern Han once wrote in the "Eastern Capital Ode": "On Mount Dusu, there is a peach tree; below the mountain, the Hundred Ghosts are inspected. The ghosts who are unreasonable are dealt with by Shen Tu and Yu Lei, who use a reed rope and feed them to tigers."
Once, the 'Yin Queen' Tian Nai Luo subdued the Hundred Ghosts, establishing the Yin Dynasty in the Demon Domain, forcing the ghosts to sign a Divine Contract with her and obey her commands.
It is said she possessed a Divine Artifact named the 'Ten Thousand Bone Soul Devouring Banner', which when shaken, could command all Yin spirits under heaven and earth.
Shen Tu and Yu Lei were two of the most powerful War Generals under the 'Yin Queen' Tian Nai Luo.
For some unknown reason, these two were also named Shen Tu and Yu Lei.
