Starting from Saving My Sister, I Overturned the Entire Xuan Yuan

This is a world that has been colonized for three hundred years! For three hundred years, all living beings in the Abyssal Realm have looked up at the stars, cultivated planetary power, and followed the star books, thinking that the Immortal Sect guards the heaven and earth, the dynasty maintains order, and the star lamp shines on the nine realms. But no one has ever really asked— Who decided all this? Fifteen years ago, the Shen family was destroyed and Shen Ye lost everything. Fifteen years later, he returned to Lingxiao Mountain with a broken sword, just to find his long-lost sister. But the closer he gets to the truth, the more he discovers that this world is far stranger than he imagined. Someone has a familiar face, but he is no longer the same person. There are people who are clearly alive but do not exist in the star book. Some people protect the common people, and some people use the name of "protection" to firmly lock everyone's destiny under the starry sky. What Shen Ye wants to do at first is to find his sister. Later, he began to wonder- What happened three hundred years ago? And who made the entire Xuanyuan world what it is today? When the first star fell from the sky, Shen Ye finally understood: What really needs to be cut off may never be just a revenge.
