Secondly, there's the "Xuanhuang Crystal".
The Xuanhuang Secret Realm is half-integrated with the universe's time and space, exchanging Chaos Qi with the outside, able to continuously nurture new Xuanhuang Crystals.
But the earlier-than-expected Great Collapse of the home universe came too soon; normally, the time within a complete Cosmic Era would be enough for the Xuanhuang Secret Realm to nurture Xuanhuang Crystals sufficient for Lin Yuan to refine to the Chaos Realm level of "Xuanhuang Physique".
Even if not achieving Chaos Realm Perfection, one could still wait for the next Cosmic Era, the era after that, and slowly accumulate.
For a being at the Chaos Realm level, waiting ten Cosmic Eras, a hundred Cosmic Eras isn't a difficult task.
Due to the premature Great Collapse of the home universe, Lin Yuan lost the stable source of acquiring Xuanhuang Crystals.
