Tower Defense for All: Sweeping Across Billions of Dark Creatures

Luo Tian transmigrates into a dark world invaded by countless billions of alien creatures. Monsters pour out of the darkness. Civilization is destroyed, and countless lives are slaughtered! Humanity is trapped behind towering defensive walls, struggling to survive! To ensure the survival of their species, all human citizens must enter the dark zones upon turning eighteen, establish defensive outposts, search for supplies, and do their part to keep humanity alive. Luo Tian awakens the crappiest plant-type defense system and nearly dies right from the start. Just as he despairs, he binds to the Infinite Evolution Defense System! A Thornflower evolves once into a Two-Headed Thornflower, twice into a Thorn Guard, a third time into a Thorn Warrior, and a fourth time into a Phantom Banshee!” From then on, a host of stunning, willowy plant fairies follow Luo Tian into the dark tide, slaughtering their way through it!
