Above the heavens, winds and clouds raged, countless bolts of lightning roared, and endless darkness descended. In this vast, boundless world, one man shone like a blazing sun, dazzling and radiant! He was the Devil Emperor who had once swept across the eight directions and six realms, shaking the Myriad Worlds!
Now, he had been reborn. The glories and humiliations of the past burned in his heart, fueling a raging fire of fury. Carrying boundless hatred and obsession, he embarked on a revenge-filled path of thorns and slaughter.
The skies and clouds changed color, mountains and rivers trembled, and all under heaven shook at his return! Cold determination gleamed in his eyes, and every step seemed to fall upon the very heartbeat of all living beings.
He would make the world tremble, and reduce those who had once betrayed and hurt him to ashes in his fury!
