Tower Defense Lord from Earth

Liu Huasheng, a solo gamer from Earth, finds himself transmigrated into a world of tower defense, where he becomes the supreme ruler of a tower defense lord. Guided by a game assistant, he constructs his towers, and to his surprise, they become key players in the world's battles. His No. 1 tower proves itself a formidable defense against ferocious beasts on February 14th, while No. 2 earns the title of model worker by February 30th. On March 8th, the third tower is launched, successfully capturing a kobold princess, and a subsequent return visit from her reveals an astonishing truth: the Earth is flat. Meanwhile, No. 4 generates an astonishing 100 million kilowatt-hours of electricity, and by August 15th, the fifth tower, piloted by his subjects, takes on the Ancient Battlefield, where they will engage in a decisive battle against a monster army.
