[No fixed cp + non-fixed gender + non-conventional plot + one in each plane + difficult to reconcile + female protagonist is sober and ruthless]
In the world of immortality, a female Shusuya transformed into a thousand wild grasses and was suppressed by the male and female masters in her previous life as a demon king. When she was about to be killed, she used her fighting power to tear open the rift in time and space and go back to the past to ascend to escape the tribulation. In her previous life, she failed to survive the tribulation and was almost struck by the thunder of heaven. She finally took away the body of the demon cultivator and changed from the immortal way to the demonic way.
In this life, she was going through another tribulation. She originally planned to take advantage of the thunder tribulation to enter the demonic path again. Who would have expected that she would be bound to System 0902, which happened to pass through the small world. The full name of the system is the Cannon Fodder Rescue System.
0902 Thought he was lucky enough to be bound to a highly matching host.
Who would have thought...
The host turned out to be the future villain of the original world!
Host, you are saving cannon fodder, not subverting cannon fodder!
