Of course, not everyone who died unjustly could enter the Wrongful Death City.
If one had committed too many sins in life, they wouldn't be considered as having died unjustly but rather having died with unresolved guilt. After death, their soul would be cast directly into hell, so there would be no need to enter the Wrongful Death City.
However, due to the lack of supervision in the Netherworld, a small change had occurred with Jiang Chen's Wrongful Death City.
Yes, since there was no supervision anyway, Jiang Chen simply expanded the authority of Wrongful Death City. Initially, it could only accept those who died unjustly, but now, any wandering spirit had to be collected into the Wrongful Death City.
Jiang Chen dared to do this precisely because of the utter lack of order in the Netherworld. If there had been a complete order in the Netherworld, how could such an act by Jiang Chen have been allowed?
