I Suppressed the Foreign Races for Tens of Thousands of Years, Only to Return and Be Told I'd Been Reincarnated

[Overwhelmingly Powerful] [No Saintly Heroics] [Villain] [Ungrateful Wretches All Reborn] [Exhilarating Revenge]

Gu Junlin, the Heavenly Emperor who suppressed the alien races for countless millennia and safeguarded peace for humanity.

Once the pride of his parents and a hero to humanity, he one day received word that he had already been reincarnated.

The family, friends, and loved ones he'd fought so hard to protect had mistaken an impostor for him!

His fiancee was going to marry the impostor.

His parents treated the impostor like their own son.

His younger siblings treated the impostor like the best big brother in the world.

Meanwhile, Gu Junlin bore the infamy of ten thousand lifetimes, scorned by his family and betrayed by humanity!

With one final, glorious burst of power, he killed every ungrateful wretch, freed the progenitor of the alien races, and slaughtered the humans who had betrayed him!

Reborn for another life, his family and the ungrateful wretches were reborn too!

In their previous lives, they had thrived thanks to Gu Junlin's wholehearted support.

This time, they thought they could do even better without Gu Junlin, perhaps even surpass him.

But life turned out to be a complete mess.

Without Gu Junlin's help, their lives grew more and more miserable.

When they finally regretted everything and went looking for Gu Junlin,

they discovered that the son they remembered as so gentle, the best master, the kindest junior brother,

had become someone they no longer recognized at all…

Gu Junlin: If the world is doomed, what does that have to do with me?

The alien races are invading? None of my business!

If you don't die, does that mean I have to?

In this life, I am the Heaven-Refining Demon Lord. I live only for myself!

All you ungrateful wretches, into my Human Emperor Banner!
