I'm the Villain

After waking up, he finds that he has transmigrated into another world as the great villain of a demonic cult, while his best buddy has become his dog-headed strategist. A man and a dog, endless laughs, and deadly official snark.

The two of them can only save themselves by completing their mission.

They recall the usual tropes, stop the protagonist from reaching the top, cultivate the protagonist's techniques, innovate with technology, revive the demonic cult, rewrite the villain's fate, and unite the continent of another world.

"Could we have transmigrated back to our past lives? I was still human in my previous life, but you were a dog?"

"Get lost."
