The Sky Is the Frontier

The deep space resource belt is coveted, starship routes are blocked, and the tentacles of extraterritorial forces have reached the edge of the solar system. In 2088, the Chinese deep space exploration team encountered an unknown armed attack, energy data was stolen, and the outpost was destroyed. Song Mengju, an engineer who just woke up from the accident, unexpectedly discovered that behind the attack, there was a conspiracy against the development of China Interstellar. From orbital defense platforms to Pluto outposts, from antimatter reactors to starship main guns, she carried a secret plan called "Vault" to break technical barriers again and again, and launched fierce confrontations with foreign forces. Some people say that China should not get involved in deep space; some people say that our territory should stop at our home star. But Song Mengju and her comrades responded to doubts with the roar of engines, guarded the route with the main guns of starships, and used Chinese wisdom and tenacity to carve out a path that belongs to us in the cold universe. Under the sky are all the borders of China.
