In 2145 AD, mankind entered the "Star Energy Era". The ancient "Star Aperture" technology ignited the flame of supernatural awakening, but it also brought fatal pollution that corroded the mind. The interstellar plutocrats shroud the world like a shadow, greedily absorbing the star energy and the foundation of earth civilization - the "star marrow". In this universe reshaped by technology and madness, a forgotten ancient profession has quietly reappeared - knife creditor.
Lu Li, the last descendant of the Credit Sword, possesses a rare immunity to star energy pollution. The knife in his hand is not extraordinary iron, but a causal weapon flowing with programmable nanoparticles. The pattern of the knife is a code. Each stroke can cut off bad luck, predict the future, and collect heavy karmic debts. Living on credit among the dust and neon of the Martian colony, he only wanted to find his missing master, but he accidentally got involved in a conspiracy that subverted the universe.
An operation to cut off the "chain of misfortune" for marginalized people activated the ultimate sword pattern program left behind by the master, revealing the Hermes Group's plan to enslave all living beings with the "happiness chip" in an attempt to extract the marrow of the earth. The immortal capitalist "Zeus" who hangs high in the earth's orbit and whose consciousness has been transformed into a group of quantum satellites has become the "biggest cause and effect" that Lu Li must cut off.
He was forced to embark on a journey and formed a life-and-death alliance with Zhang Jiuya, a cyber Taoist who was engraved with a talisman, and Noah, a transformed girl who could communicate with the stigmatized star beasts. Their footprints span the sea of stars: from the core ruins of Dunhuang Mogao Grottoes to the dangerous cemetery of Beta Monoceros star beasts; their battle transcends the laws of physics: using knife pattern programming to fight against the forces that rewrite the cosmological constants.
