"Is that why you were at the Extreme Yin Lake? To improve your Cold Immunity?" Sun Ling Cai asked.
"That's right. I need to train my body in a place with extremely strong Yin Qi."
Sun Ling Cai pondered for a moment before speaking, "Actually, I might be able to help you in this regard."
She retrieved a scrolled painting from her spatial ring and continued, "This is one of my masterpieces. It's called 'The Cold That Cuts Heaven', and I painted it when I visited the White Hell, one of four forbidden zones within the Nine Heavens."
"White Hell? What kind of place is that?" Yuan asked, his curiosity sparked upon learning it was one of the four Gateways to Hell, much like the Vanishing Valley.
"It's a land where the snow never stops falling—a world buried in endless white, which is how it got its name," Sun Ling Cai explained. "It's also one of the coldest places in the Nine Heavens. Even Immortals can freeze to death there."
