What Happened…
Yu Xuan's persona, whom he later named Book-Human went to the Chaos Heaven Peak with a purpose so simple it sounded absurd.
To read.
Not to cultivate.
Not to fight.
Not to scheme.
Just… to read.
Philosophy and culture.
Ancient lore and random histories.
Techniques both orthodox and unorthodox.
Plants, beasts, minerals, star charts, rituals, languages literally anything.
Thanks to Yu Xuan's status and authority, this persona possessed access to the Great Heaven's Library of the Heaven Immortal Sect.
It was there, buried among volumes most cultivators skipped entirely, that he found a thin, unassuming book.
Its title was simple.
Spirit Realm.
At first glance, it appeared academic – dry descriptions, fragmented theories, contradictory testimonies.
Yet the deeper he read, the more unsettled he became.
The Spirit Realm was not merely a "realm."
It was a layer of existence.
