The Reborn Immortal Master Seeks the Country

Possessed by divine light and powered by a demonic soul, I am the emperor of the ten kingdoms and the supreme master of the three religions. I am a prodigy and possesses the wisdom of the past. If I were to dominate the world, who would be my enemy? But I am willing to serve as a military advisor for the country. Brothers? Beauty? Common people? Mission? Although I have great wealth and power, I am free and happy in this world. Since God allowed me to be reborn, I shouldn't just be a mortal, I should be the only immortal master in all eternity!
