At first, Wang Quan thought Underworld Protection was of little use.
The three traits-"the Underworld is my home," considerable renown in the Underworld, and doubled gains of yin virtue-were of little use.
But after it merged with [Comprehend Yin and Yang], he discovered:
The trait "the Underworld is my home" was quite interesting:
With his current Underworld Protection and [Comprehend Yin and Yang] abilities, he could freely enter and leave most of the many buildings in Emperor's Tomb City's outer ring without being discovered by living creatures.
The restrictions, ritual defenses, and so on within those buildings could not stop him.
He could even bring other Underworld beings freely into and out of most buildings in Emperor's Tomb City's outer ring without a key.
As for the trait of having modest renown in the Underworld, it gave him greater prestige; when certain things happened, more people would believe what he said.
What astonished him most was the doubled gain of yin virtue.
At first, he had thought the Underworld was merely a world of ghostly affairs; the so-called yin virtue was utterly useless.
But after mastering [Comprehend Yin and Yang], he discovered:
Yin virtue was actually very important.
So important that ordinary Underworld beings, and even many ghost gods, did not know just how important it was.
The Underworld was vast and held many secrets.
And those secrets required yin virtue to make use of them.
Had he known the mysteries of yin virtue back then, he could have secured a small courtyard residence covering one mu in City No. 95 without giving Ghost God Soft Bristle any gifts.
*If I tell the Drowning Dao about the secrets of yin virtue, I'm afraid that in less than half a day, all 108,000 cities of the Far Western Land will establish
