National Games Game I Am a Deus Ex Machina

(Single female protagonist + national destiny + no male protagonist + discussion of human nature) The earth's resources are depleted and a world war is about to break out. The National Games Game suddenly comes to stop the war. The heroine Zhang Lingze accidentally falls into a cave and almost dies. At the last moment of her life, she merges with the ruins in the cave to obtain a machine deity system and enters the National Games Game. As her body continues to transform and evolve, she gradually loses her humanity and becomes a robot, but her heart to protect the Rabbit Kingdom remains unchanged.
