Su Qinghan, the iceberg guardian who has guarded the ancient seal for generations, accidentally met Feng Wuyue, the evil female mountain bandit who came to snatch the treasure during a seal movement. A fierce battle caused the core of the seal to break, and the two were forcibly bound by a mysterious system called "Cooperation". From then on, what one person does will accumulate "karma" for another person. Doing good deeds will gain "good karma", and doing evil will gain "bad karma". Karma can be exchanged for extraordinary abilities.
Two sworn enemies with completely opposite personalities, positions, and behavior styles were forced to embark on a symbiotic path of scheming against each other and "feeding" each other's karma. In order to gain powerful protective power, Su Qinghan had to "ask" Feng Wuyue to rob the rich and help the poor; in exchange for the ultimate destructive power, Feng Wuyue had to "force" Su Qinghan to hang the pot to save the world. From the initial mutual dislike and extreme pulling, to having to join forces when facing a common powerful enemy, they turned each other's "evil" into their own "shield" and each other's "goodness" into their own "spear". As the secrets of the system are revealed, a shocking conspiracy involving ancient gods, demons, and the fate of the dynasty emerges. They eventually change from mortal enemies to the only partners who can be trusted to back them up. They join forces to overturn the good and evil in the world and redefine the world. The highlight is the strong conflict setting of "dead enemies are forced to cooperate" and the unique combat mode of "use your evil to protect me and use my good to destroy you", which is very exciting.
