Wang Xiaoming wandered into an employment agency and became the night watchman of a mysterious cargo hold. Golden marrow flowed across the shelves, while the corpses of emperors from every dynasty were sealed in freezers. Each transaction brought the cargo hold one step closer to the abyss. It turned out to have been formed from the spine of A Yuan, the Dragon Clan princess who was tortured to death. A dragon-tail tattoo beneath a woman's red skirt, a male corpse in a freezer with Wang Xiaoming's face, and a god-slaying blade whose hilt was covered in tally marks of the character "justice" drew him into a karmic vortex of ten thousand reincarnations.
After every ten transactions, the cargo hold rose another level, unlocking a new execution ground: a human-sacrifice scale that devoured lifespans, a ghost-wedding freezer that awakened tyrants, and a Ten Thousand Souls Banner that turned against the Four Realms. The instant Wang Xiaoming raised his blade to strike A Yuan, the cycle began anew. It turned out he had long since become the executioner of the thousandth reincarnation!
At last, the cargo hold broke through a thousand layers of seals, and the Dragon King's resentment devoured heaven and earth. Wang Xiaoming traveled back in time to the beginning, where he discovered that A Yuan had willingly been imprisoned for nine thousand years. He refined himself into the core of a new cargo hold. Within the closed loop of cause and effect, fragments of a marriage contract drifted down inside the amber where the frozen corpse and A Yuan embraced, revealing that all those reincarnations had been nothing more than a thousand-year tribulation of love between the Dragon Clan princess and the fallen dragon prince.
