Dimension Guardian: Transmigration and Rebirth

During an unexpected transmigration, the protagonist, Li Liang, arrives in the Ming dynasty and acquires a mysterious System. Using the military strategies and special abilities it grants him, he gradually makes a name for himself in this unfamiliar era. As the story unfolds, however, Li Liang realizes that his transmigration has triggered a massive crisis: the world's coordinates have been exposed, attracting the attention of powerful beings from other dimensions. He must now face the threat of an alien invasion and do everything he can to protect the Ming dynasty's peace. Along the way, Li Liang meets another transmigrator, Luo Ying, whose abilities resemble his own but whose personality is entirely different. They go from opposing one another to fighting side by side, then find themselves at odds over their mission to protect the worlds, embarking on a series of thrilling adventures. Just as Li Liang believes he has found a chance to return home, he becomes entangled in an even greater conspiracy: the succession mechanism for the guardian of the dimensional nexus has been triggered. Li Liang gives up his own energy to save Luo Ying, only to be betrayed by the new guardian and stripped of his powers. But just as Li Liang falls into despair, Luo Ying wakes up. Together, they rediscover the courage and resolve that first inspired them to protect others, realizing that a guardian's true strength comes not from a System or a title, but from courage and love. In the end, they decide to return to the dimensional nexus together, continuing to protect more worlds and face whatever new challenges await them.
