Jiang Wan, a female god of war in the cultivation world, transmigrates into a criminal slave on the Z-7 radiation-blighted barren planet, facing a death sentence by execution. In front of the crowd, she chooses the dying, disabled Marshal Huo Xiao to sign a military dependent blood pact, using her wood-type origin to purify radiation, spawn a sea of grass, man-eating flowers, and a thousand-meter mother tree, transforming the barren planet into a sky garden. From dodging whips and seizing lashes to using photosynthesis rice to pension veterans, and feeding supervisors to vines and purifying the entire planet with the mother tree, she step-by-step fights back to kill the governor, the second prince, and the North-Suppressing King. Huo Xiao recovers from being a disabled person to possess SSS-grade spiritual power, becoming her hardest shield. The couple overturns old imperial cases, the Z-7 planet gains independence, and Jiang Wan becomes the master of the universe's number one garden.
