Iron and Sail

On the gravity purgatory known as "New Terra", the form of war has been completely rewritten. The Northern Federation, which mastered the energy of "Pyroxene", built a steel behemoth suspended in the sky - the "Ark" class air battleship. Their main guns can vaporize mountains, and their carrier aircraft swarm like a swarm of dead bees. In the past, the Xinghan Empire relied on the earth and the torrent of steel. In front of the destructive flames falling from the sky, its impregnable defense line was as fragile as paper. This is a dimensionality reduction blow. It is the one-way judgment of the sky on the earth. However, the Empire did not surrender. They used the whole nation to steal and study it, vowing to forge their own sword in the sky. And the Tianhan Republic, which relies on trade and wisdom, must also make a choice: spend huge sums of money to build a fragile air barrier, or place its destiny on a dangerous alliance? When the shadows of the fleets of both sides cover the continent, and the cannons of destruction are pointed at each other, the planet itself, which has been dormant for thousands of years, seems to have begun to cast a silent gaze on the commotion... This is the ultimate showdown between air superiority and absolute firepower in a gravity cage. Welcome to the sky era where giant ships and cannons dominate everything
