Ling Yunpo drilled out of the stone chamber, stealthily following the little demons through a series of turns, only to see the terrain increasingly sloping downward.
Soon, he arrived at the second chamber.
Upon opening the stone door, a high concentration of salty water rushed out.
"Salt! Salt! Salt!" the little demons cheered three times, then hurriedly closed the stone door.
Before the stone door closed, Ling Yunpo fixed his gaze and saw on the chamber floor a Water Gathering Formation engraved.
The so-called Water Gathering Formation was designed to extract water from a source and transport it elsewhere—for instance, many sects relied on Water Gathering Formations located elsewhere to supply fresh water for their ponds, preventing the water from going stale and foul.
It is worth mentioning that the Water Gathering Formation would only extract pure water, leaving behind algae, suspended particles, toxins, and even fish, unaffected by the formation.
