Brother, Holy Lord, and I, Demon Lord, are the Rulers of the Immortal Realm

[A top figure in the cultivation world, both righteous and wicked, with decisive ruthlessness]An unexpected event transported Xiao Ran and Li Ping'an, who were in a foot massage parlor just a moment ago, to the world of cultivation.Xiao Ran transmigrated to the Eternal Night Demon Sect and happened to awaken the ancient holy body "Myriad Paths Return to the Void Body", and was directly named the Demon Prince of the Demon Sect.At the same time, Li Changsheng transmigrated to the Supreme Dao Palace, where he awakened the ancient sacred body "Innate Dao Embryo Sacred Body" and was directly named the Holy Son of the Dao Palace.The two brothers belonged to different sects: one a demonic sect, the other a Taoist sect.Fortunately, the two awakened the system and discovered that their consciousnesses could communicate with each other at any time.Xiao Ran: "I'll be a demon prince in the demonic sect, and you'll pretend to be a holy son in the Taoist sect. When we're able to protect ourselves again..."Li Changsheng: "And then?"Xiao Ran chuckled: "And then? Both the righteous and the wicked are under our control, so the cultivation world is just the two of us calling the shots?"...then.From then on, a legend spread throughout the cultivation world: Xiao Ran of the Demon Sect was exceptionally talented and became the supreme ruler of the Demon Realm in just a few decades.Li Changsheng of the Daoist sect was equally formidable, having become the leader of the righteous sects in just a few decades, and the undisputed supreme leader.Legend has it that the two were mortal enemies from the moment they rose to power... So when they became the Demon Lord and the Holy Lord, they would launch a war between the Dao and the Demon every now and then, each time causing great suffering to the people.However, the two men, who seemed like sworn enemies to outsiders, were actually good brothers in private."Good brother, in this great battle, all those who disobeyed us in the Demonic Sect are dead.""Hehe, good brother, we Taoists are too.""Could you send me two of your succubi?""Dude, your holy maiden over there..."
