There is Huangquan under the Nine Netherworld, but there is no scenery on the road to Huangquan. There is only a house on the other side of the Forgotten River that appeared at an unknown time, called the Huangquan Inn, for those who are destined to rest and stay temporarily.
PS: Soul Replenishment is the first part of this fan series. It's already finished. As for whether we want to dig deeper and continue to watch the second part, it depends on whether the GNs have the desire to continue watching. The second volume is going to take the rape and torture route of falling in love and killing each other.
