The Qi of Late Winter due to its involvement with the forces of time, can be referred to as a rare treasure in the Lower Realms. Even within the Rongcheng's Fine Jade Grotto Heavens, there's only one piece of ancient profound ice formed from the Late Winter Qi, which demonstrates its rarity.
Especially for the Primal Chaos Realm, which has fallen into periods of Spirit Energy depletion multiple times, the Late Winter Qi that can freeze and preserve one's vitality to survive catastrophes is a supreme treasure for avoiding calamities.
Although the Late Winter Qi is limited by the quality of the Qi of heaven and earth, and cannot completely freeze those who are above the Spirit Refining masters, if the ancient profound ice emerges, even the Void Refining True Monarch would seize it at all costs.
However, this Heaven and Earth Qi, which can be regarded as a divine treasure, was effortlessly manipulated by Shen Yuan.
