"It takes five hundred years for a Water Snake to transform into a Flood Dragon, and a thousand years for the Flood Dragon to transform into a Dragon. It takes another five hundred years to become a Horned Dragon, and a thousand more to attain the level of an Ying Dragon."
"A Flood Dragon is not truly a Dragon, as it still has a ways to go before it reaches dragonhood. During torrential downpours, the process of the Flood Dragon descending along the water flow into the East Sea is known as 'Walking Dragon.' Walking Dragon is the final step for a Flood Dragon—or any other enlightened creature, such as turtles or soft-shelled turtles—to transform into a Dragon."
"During the 'Walking Dragon' phase, it often triggers flash floods. In secluded mountain regions with sparse human activity, this may not be a concern. However, in densely populated areas, it often leads to severe disasters. This is why there's a saying: 'A Flood Dragon traveling down water brings havoc to all quarters.'
