This is an apocalypse with exhausted spiritual energy - "Ember Earth".
After the ancient spiritual veins collapsed, the earth cracked and gray mist floated in the air. Ordinary plants could not survive, and only a few spiritual plants that could absorb weak spiritual energy could grow.
Human beings live together in dilapidated "barrier cities" and rely on planting low-level spiritual plants in exchange for survival supplies. The strong make a living by plundering spiritual plant resources, while the weak can only struggle at the bottom.
There is a truth hidden in the world: spiritual energy has not disappeared, but is locked by an ancient seal. The only one who can unseal it is the "Heart Planter" who can resonate with all spiritual plants.
