Blue Heaven Province's Bad Reputation

The hall was completely sound-proof but this kind only blocked the outer noise from entering while the inner noise could go out, it was quite strange.

If there were to be anything going on inside the hall, those outside could discover even if it was a single sound wave that escaped into their notice.

However, if there was a battle on the outside of the hall, those who were inside could barely hear any voices while within the hall.

But in the cases of the really powerful Dao Soul realm cultivators, the soundproof mechanism was only outward extravagant display.

This was because with powerful spiritual consciousnesses, it would not be exaggerating to state that they could easily survey a whole city in just a single flash like how Xiao Yunhai from a few years back did as well in his own case since the spiritual consciousnesses could easily capture anything that had become focused in its reach as easily as the flip of the hand.
