In the giant pit below, the ghost soldiers on top stepped on the shoulders of the ghost soldiers below, waving their hands, desperately trying to climb up. Fortunately, the pit was deep enough and the slope steep enough; otherwise, these ghost soldiers might really have made it to the top.
Hei Gu asked, "Your Majesty, how should we deal with these ghost soldiers?"
The Ghost Emperor said, "Bury them."
Hei Gu said, "They cannot die. Even if they are buried below, they still won't die."
The Ghost Emperor said, "Hei Gu, have you ever heard of the Demon Suppression Tower?"
Hei Gu nodded and said, "Building the Demon Suppression Tower is not too difficult; the hardest part is the seal on the tower, which requires someone with very powerful cultivation to make it effective."
The Ghost Emperor said, "With the combined strength of the three of us, we should be able to seal the Demon Suppression Tower. With the tower suppressing the ghost soldiers below, we can ensure temporary peace."
