A young man who had longed for stories of good and evil since childhood lost his life in a tragic accident and was reincarnated as a boy named Chrono Mak in another world.

He learned that in this other world, there is magic and witchcraft, and depending on how you train them, you can become as strong as you want to be, so he decided to become the strongest demon king in order to recreate the story of justice and evil he once dreamed of.

The past life Ji Anran: “Geng Yan, let’s get back together.”

Geng Yan, who was dumped: “I refuse. You have powers anyway, and you can live well without me.”

After rebirth, the weak chicken Ji Anran: “Geng Yan, let’s get back together.”

The dumped Geng Yan: “I refuse.”

Ji Anran, lying dead: “I have no power, you don’t care about me, just let me get cold1.”

Geng Yan: “… …” The unsuccessful Geng Yan can only take away the weak chicken, one cannot put sand on the wall2 Ji Anran.

Later… what about the ordinary person without the strength to truss a chicken?! Who’s the guy in the day?

Su Jie, capable of traveling between Blue Star and the Cultivation World, discovered that cultivation was just too difficult.Spirit Pills, Magic Artifacts, Pocket Worlds, and inherent comprehension—each was a mountain on the long road to immortality.Not until Su Jie found out that Demon Cultivators refined corpses by killing, extracted souls to cultivate fiends, and used fear as sustenance for their cultivation.Need souls to consecrate a Soul Summoning Banner?

Stock up on ghost houses, horror films, and horror games…Need fresh blood for Demon Techniques?

And you still have the face to call yourself a good person? Pah, today I shall act on behalf of heaven to mete out justice.”The Tianyuan World’s most beautiful person’s eyebrows were furrowed with rage, as she stared at the terrifying Devil before her, enveloped in wronged souls, with thousands of ghosts parading on his Soul Banner, seated in a palace made of bones, she posed her soulful question.The Devil slowly stood up and pulled out a business card that read “Hua Country’s Philanthropist of the Year / Founder of the World’s Largest Chain of Ghost Houses / Owner of Blue Star’s Largest Livestock Slaughter Business / Emerging Tycoon of the Entertainment Industry.”“You see, I’m really not a devil, okay? Nowadays, who still uses such a lowly method as killing people to cultivate as a devil!”
