Xia Ruofei spent six or seven hours exploring all three caves pointed out by senior copper coffin.
Senior copper coffin had pointed out locations well within Ruofei's capabilities. An ordinary late-Stage golden core cultivator might not have successfully claimed all the opportunities, but Ruofei was significantly stronger and possessed far more tricks up his sleeve. While his exploration wasn't entirely smooth sailing, he successfully obtained the rewards from all three caves.
Inside these caves, he obtained a piece of purple-gold cloud iron, a stalk of mysterious fog grass, and an illusion gold elixir.
Purple-gold cloud iron was a top-tier material for weapon refining. If even a small amount was added when refining a flying sword, the weapon's grade would increase by at least one level. The piece Ruofei found was the size of an adult's fist, highlighting its immense value.
