I Am a Demon King, so It Makes Sense for Me to Possess the Merits of Heaven.

Villain + swordsmanship + decisive killing + no heroine In the Gobi desert, millions of righteous men surrounded Cai Kun! "Demon Lord without Borders! You use the lives of tens of millions of creatures in the world to refine your sword intent to kill! Forge the great demon sword that will destroy the sky! The crime cannot be forgiven, and everyone will be punished!" "Today I, the heroes of the righteous path, will kill you here to comfort the dead people of Dawn!" … Amidst the excitement of the crowd, the leaders of the righteous path all took action! The awe-inspiring righteousness, the Vajra King, the heavenly thunder righteousness, the earthly fire surges! There is even a strong man who inspires the merits of heaven and comes to kill, hoping to kill him with one blow! These extremely strong and impartial forces possess powerful suppressive and corrosive power against demonic cultivators. If an ordinary demonic cultivator encounters this, he will die on the spot if his skin is pierced and his flesh is rotten! But Cai Kun was unmoved at all. The heaven-destroying attack hit him, and he saw boundless bright golden light suddenly blooming around him, blocking all attacks! The heroes were shocked: "How come you, the Demon Lord, are blessed by heaven!" … Come to this world and become a demon cultivator. Cai Kun is bound to the system and can travel to other worlds! And these worlds are none other than the war world and the zombie world! On Asia, he slaughtered the little devils crazily; on Europe, he killed the Nazis to pieces! In the zombie world, he kills the zombies and purifies the world! In a strange world, he tortures and kills ghosts to save the common people! Heaven sends down merits and praises his great achievements! Cai Kun: "Don't panic. Although I am the Demon Lord, I have never killed anyone!"
