Gao Tianqiu

He was once the co-lord of the Nine Heavens, but he was deposed and imprisoned in the abyss. Breaking through the abyss, he took root in Qianji City, kept watch at night with his broken body, and supported the sky with his body pillars. Nine human pillars, three keys, a third way to "integrate within and return to the ruins" - when he gathered all his strength, he found that the final choice was not to open the seal, but to sink into the dream of the ancient gods and return to the ruins forever. Everyone in the world thinks he is guilty, and no one knows about the night watchman deep in the ruins.
