1402 Emperor Jianwen's Space-Time Fleet

In 3036, at the beginning of the mighty Earth Defense War, Lin Yunqi opened the cutting-edge technology "Space-Time Anchor" system he participated in the research and development in order to escape during the second round of far-Earth orbit fighting. However, due to imperfect technology and the collapse of the wormhole, he traveled back to the Yingtian Mansion where troops were approaching the city in 1402. Lin Yunqi, who was looking for a way to return home in the past, unexpectedly discovered that the mysteriously missing emperor in history had become the key to the victory of the earth's civilization through an unexpected combination of circumstances. A misplaced time and space travel, a life and death battle, an unsolved case in history, can he turn things around and save the fate of the people on earth? Of course, becoming a savior comes with a hefty price tag.
