Wasteland: I Let Others Be Gu Masters

I am a book named "Hope". Civilization collapsed and the land became a dead wasteland. In the wilderness, countless mutated ferocious beasts roam, their fangs and claws harvesting lives. The remaining humans huddled in high-walled cities, relying on barriers to resist the threat of death from outside. I am sleeping among the broken walls and ruins. I have no flesh and blood body, I can't swing a knife, I can't run. But I can choose a mortal in desperate situation and give him the power of a Gu Master. The empty orifice accepts the poison, the will controls the poison, collects the poison material, and refines it for use. Those who gain power can hunt down mutated ferocious beasts and earn a living in the wasteland. But Gu Dao is inherently cruel, with scarce resources and unpredictable people. Some people use my power to struggle to survive, while others sink into desire and turn into dust amid calculations and fighting. What is hope? Is it this hard-won power of Gu Dao, or is it the human heart that refuses to be extinguished in desperate situations? Is it okay to decide whether to leave after reading ten pictures? 😭😭 It's not a first-person tomato, this is a random design
