Qin Lin was playing a nostalgic game called “Ranches Story” when he was electrocuted. He suddenly discovered that he had the ability to enter into the game. He could even bring a watermelon he had planted in the game back to reality.

At first, his plan was to sell watermelon for 2 yuan a catty. In that case, he could earn 20,000 yuan by planting 10,000 catties worth of watermelon in the game every day and selling them in reality.

Later on, he discovered that by leveling up his ranch, he could obtain high quality crops that surpassed that of the real world. If he reared livestock, they were of far higher quality than that of reality. After he built factories, he obtained various recipes that far surpassed that of the real world. Everything changed after that.

After the judgment, the ire of God was revealed with the words: “Be cast unto eternal damnation!” And so it was that humans and jinns alike found themselves scattered across the Nine Circles of Hell, left to burn and suffer for eternity. Until after an untold number of eternities, an angelic voice called out, announcing God's decree: “One soul shall earn the chance to return to grace.” Humans and jinns found a shimmering screen appear before their eyes, tallying their sins and something called 'Fragments of Divinity'. “Cleanse away your sins,” said the voice. “Do what must be done!”Now, a human known as Wretched Nameless One—the only human found in the Ninth Circle—sets out on a journey to claim his spot in Heaven, tasked with fighting hellish monsters and devilish hell-dwellers competing to return to grace. Will he escape eternal torment and rise to grace or return to the everlasting cleansing fire once more?
