Chapter 324: Chapter 323: Qilin Immortal, I've remembered you!_1

"Right, this is the mud I found, Breath Soil." Kirin Immortality Medicine regained its composure after the shock of the immortal battle and remembered why it was here.

"Breath Soil, is it the legendary kind that just needs a small piece to obstruct a river?!" Lu Yang had only seen this precious soil in books. Because of its magical effects, it was known by people as "Immortal Soil".

Fairy Eternity walked around the Breath Soil a few times and recognized its origins: "Oh, this is a good thing made by the Immortal Jiuchong. It swells when it encounters water and is used to control floodwaters."

"Back then, our river channels were a mess, frequently flooding, and the tribes were all settled by the river. This led to massive casualties every time the river flooded, making it difficult to rebuild afterwards."
