Nantianmen: Heavenly Guards

In 2045, China spent twenty years devoting all its national industry and aerospace technology to build the Earth-Moon full-area aerospace defense system - the Nantianmen Project. The Luan Bird space carrier is located in a synchronous orbit of 42,000 meters, the Baidi fighter jet is a sharp knife for deep space assault, tens of thousands of Xuannv unmanned aerial vehicles are building a swarm to intercept the skynet, the Chengying heavy-duty mecha is guarding the lunar fortress, and the purple fire take-off and landing platform is connected to the logistics supply of heaven and earth. The five major equipments complement each other and build mankind's first line of defense in the sky. Under the long-term peace, the world only regarded this system as a science fiction romance of a great power, until a space rift was opened outside the Oort Nebula, and the symbiotic civilization was plundered and invaded the solar system across light years. The alien ship shields swallowed up all kinetic weapons, human beings' conventional orbital defense lines collapsed one after another, and the survival of civilization hung on a thread. Luanniao Captain Lu Heng is in charge of the Sky Center, ace pilot Zhao Ye drives the White Emperor into the battle, chief engineer Su Qinghe reverse-engineers the alien technology, and lunar commander Qin Zhenyue leads the Chengying Mecha to defend the Kunlun Fortress. Bee swarms cover the sky, mechas are bathed in blood, and giant ships are arrayed. If there is no way to retreat, then use the Sea of ​​Stars as the battlefield and Nantianmen as the barrier of home and country. If the sky is not broken, China will not retreat!
