Lobi, an expelled hobbit boy, struggles to survive in a post-apocalyptic garbage dump and accidentally activates the spiritual spring space in his ancestral button. Each drop of spiritual spring can purify mutated creatures or cultivate special plants. He secretly cultivated an army of piranha flowers that devour zombies and a super food that cures viruses. On the surface, he is a humble and abandoned son of a shrinking tribe. Secretly, he uses mutant beasts and new civilization technology to crush all forces. Finally, he uses the Hobbit bloodline to unlock the ancient ecological mother tree and transform the doomsday earth into a new Eden.
