The remains of the former "All Things Calibrator", an eternal "zero crack" gives it a new mission: to sense and attract the strongest "regret" in the universe. The ship's weapon spirit was the architect and the only sinner of that disaster. He lost his name and became Zhou Lao, a watcher who carries out eternal atonement by "witnessing".
Visitor: Any soul with huge causal fluctuations caused by regret, confusion or longing.
Transaction: Visitors pay for their core "concepts" (such as obsession, glory, logic).
Gain: Get an opportunity to see clearly the truth about your destiny.
Purpose: Zhou Lao collects these rewards containing "causal potential energy" and uses them as fuel to maintain the sailing of the "Ship of Untie" and heal the devastating scar in the universe.
