The Magic Weapon Is Coming, My Wife Fights Monsters and I Upgrade

The world has changed, and an abnormal thing called a "weapon" has quietly emerged. By signing a contract with it, you can gain extraordinary power and become a "contractor" walking in the world. However, with power comes an iron law: 1. The magic weapon has no source, and the contract is symbiotic. 2. The weapon has no consciousness, but those who use its power will inevitably suffer backlash. They are "those who contract ghosts." 3. The person who signed the contract dies, and the owner of the weapon changes. 4. (Note: The above rules are only established before the catastrophe.) Lu Ge died unexpectedly, but accidentally merged with the ancient bottle passed down from his ancestors, becoming the only "trick weapon" with self-awareness in the world. In order to track down the real murderer and prevent the world from collapsing, he embarked on a forbidden path: signing contracts with different "contractors", swallowing thousands of artifacts, and gradually uncovering the ultimate secret of the "Catastrophe"... And the truth about his own existence.
