Below is a developed story outline and opening chapter for: (Set in the world of A Will Eternal / Yi Nian Yong Heng ) Premise After Bai Xiaochun’s ascension to immortality and his legendary feats, the universe remains unstable. A forgotten fragment of the Eternal Flower— the ONA Origin Node Artifact —awakens in a lower realm. This fragment begins “sub-cycling”: resetting the cultivation of anyone who touches it, trapping them in an endless loop of breakthrough and collapse.
To her left, a Foundation Establishment cultivator named Kun Lei was already screaming, clawing at his own dantian. “I broke through! I reached Core Formation! Why am I back?!”
A faint laugh echoed from the shadows. A boy’s voice, ancient and amused.
Lian Shu woke to the smell of blood and lotus blossoms.
Bai Xiaochun. Or rather, an Echo of him.
“The Eternal Flower’s leftover node,” the Echo said, nodding toward the artifact. “I planted it myself. You know why?”
The same blood. The same blossoms. The same crack in the sky above the Spirit Stream Sect’s forgotten western temple.
Since "ONAOngoingSubA" appears to be a non-standard tag or placeholder, I’ll interpret it as an original fan-continuation (sub-story) set in the A Will Eternal / Yi Nian Yong Heng universe, focusing on a new sub-arc that runs alongside or after the main events.
