Shangwu responded, "Yes, cross the Netherworld Bridge and find the 'corpse' of the shadow, then you can. Night ghosts usually don't devour shadows immediately but rather put them aside for three days until the flesh dies, making the shadow more valuable to absorb."
"Can't cross it, wooden plaque." Ye Chenfeng thought of that bridge.
Shangwu tapped her forehead and a moment later, with a resolute tone, said, "Of course, I can cross it, but I must use my blood to invoke the Blood River. Once there's a Blood River on the Netherworld Road, the Netherworld Bridge can be passed. I'm about to die anyway, so I might as well help you all."
As soon as Shangwu finished speaking, the entire town fell into complete darkness.
The moonlight and starlight that had been above in the night sky disappeared entirely, and a thick, black fog surrounded the town.
A male voice appeared in the air, faintly carrying a sound of sobbing.
