The arrival of a super spectrometer in the 21st century revealed the existence of ghosts!
Now, the underworld runs rampant, and humanity grows ever weaker.
Humans have established the Dark Order Management Bureau, but even they are helpless against powerful evil spirits.
Fortunately, Helan Tang, the greatest Taoist master of the Qing Dynasty, has transmigrated here.
To him, every ghost is child’s play.
Ghost ships, extremely yin burial grounds, the ruins of the Great Yuezhi, haunted imperial consort tombs, corpse-infested lands of good fortune…
One by one, every sinister place is unveiled.
PS: There is no System in this book. The protagonist is powerful and single-handedly cuts off the yin and connects it to the yang. If that’s not your thing, don’t read!
This one is very novel and interesting, but it's a bit off-putting and it varies from person to person, but it's still worth a look.
