Old Yao had lived his entire life being accustomed to all sorts of turmoil, yet he had never seen the Water Solidification technique.
Above, a crow looked on for a long time before it couldn’t help but fly to the counter to take a closer look.
When Wu Yun tried to take advantage of the situation to pounce on it, the crow effortlessly brushed it away with a wave of its wings.
Old Yao looked up at Chen Ji, "What is the principle behind this?"
Chen Ji was in a dilemma.

Old Yao fiddled with the small crystal, wondering how a bowl of water could boil and boil yet eventually turn into ice—it didn’t even feel cold.
"What is this thing, lad?" Old Yao asked in confusion.
Chen Ji smiled, "It is exactly what you just described—the robust and domineering thing."
Old Yao grew more perplexed, "Which school of alchemy did you learn from, Huangshan Mountain or Laojun Mountain? But those Taoists wouldn’t spread such a thing... Could it be Wuji Mountain and Taiji Mountain?"
