A sudden "blight tide" swept across the world. Animals and plants mutated and died on a large scale, zombies were rampant, and the environment changed drastically (extreme climate, toxic spores, land desertification). Lin Sen accidentally awakened and became a unique "Doomsday Druid". Not only can he communicate with the remaining natural spirits, but he can also summon and control power from the polluted and distorted nature (rotten soil, poisonous swamps, mutated animals and plants, zombie beasts), sowing the seeds of new life in the desperate wasteland.
