Star Alliance Tianmen Project

Hidden above the azure earth's orbit is humanity's last line of defense in the sky - the Covenant. Ordinary people know nothing about this and still live in sunshine and fireworks, with the ocean ebbing and flowing, and city lights lighting up day and night. But outside the atmosphere, the five "Tianmen" space military fortresses in the east, west, south, north and center are quietly suspended and surround the earth in a five-pointed star formation. The east guards the Pacific Ocean, the west monitors the depth of the continent, the south guards against threats in the deep sea, the north serves as an extreme cold outpost, and the central Tianmen is the heart and brain of the entire Covenant Alliance. Peace is just a facade. The threats from deep space and the darkness of the ocean have never dissipated. When the flames of war are no longer limited to the surface of the earth, when enemies can attack from the ocean, beyond the clouds, and in the deep space of the universe at the same time, the Covenant is the ultimate barrier to protect this land and resist enemies thousands of miles away.
