Chương 837: Rich!

Although it was an exciting thought, Ling Chuxi knew the chances were slim. If the Golden Pill Sect of the past had an Ink Jade Crystal mine, the sect wouldn't have been so easily destroyed with such strong financial resources.

"No wonder that Four Wonder Array is so powerful… it's because of these mine veins," Cang Yuan murmured in realization.

Ling Chuxi had heard several mechanism masters talk about arrays. Ordinary arrays were driven by spiritual energy, so the strength of the arrays correlated to the surrounding spiritual energy. This Four Wonder Array wasn't that advanced, but because it coincidentally enveloped the White Jade Crystal mine in this area, it had continuously absorbed the spiritual energy of the crystal stones, becoming extremely powerful.

"Alright, let's rest first. Let me absorb some spiritual energy; opening the array just now was too draining," Cang Yuan said to Ling Chuxi with a sigh.
