Well, let's try this out I guess.
In a world of mystical powers and equally mystical dangers, there existed a man who united all cultivators under one empire. He was known as the Great Conqueror, for he held the flag that once conquered the entire world.
A man who stood at the absolute peak of his world.
His name? Dai Gengrui.
Thousands of years later, his empire stands surrounded by its adversaries, about to be forever wiped away from the face of the planet, unable to stand the test of time. But he did not care, for he already had conquered the world. All he did was turn his eyes skyward, regretful of being unable to conquer the heavens.
He was betrayed and killed by his own daughter, accepting his fate, he awaited whatever happened to him on the other side. Yet, whether it was fate , a joke played by a higher entity or simply an accident, he was reincarnated with all his memories, and most of his power.
In a mysterious world of unknown magic, a powerful being was reborn.
Aimlessly, he searched for why he was brought to his world, what purpose was it to bring him here with all his powers. And why, despite all his comprehension of the dao, can he not understand the ridiculous nature of this world?
For the first time in tens thousand years, Dai Gengrui stood without a sense of purpose, without a will to conquer. That was until a voice called out to him.
"Hey yo, wanna join the Secret Society of Reincarnated Souls?"
He was intrigued.
TL;DR: Isekai-Mystery with reincarnated Xianxia 'final'(not really) boss. MC is OP to the point they can't get serious without the world blowing up on them, so they kinda stick to in-world powers instead.

Honestly, I'm curious on how much potential readers the current title and synopsis would attract, kinda deciding on changing it.
