When I Die, the King of Hell Asked Me to Develop a Management System for the Underworld.

King of Hell: "Mr. Chu, I have prepared some small gifts. Please come to hell to pick them up when you have time." Bai Wuchang: "Mr. Chu! I have been upgraded to a ghost fairy! Where can we go to fight ghosts?" Chu Xian: "... Can you wait for me to remove the bug first?" The ghost mouth of the underworld exploded, and the demon revived. After the programmer Chu Xian died in vain, he built a backend management system for the underworld. The efficiency of the underworld was greatly increased, and the world gradually became peaceful. Chu Xian: "You hit my foot with your head. Can you please move it away? I hope you don't know how to lift me." Headless female ghost: "How dare a mere mortal... Ah!" Demonic Monk: "I'll accept your yang energy… Ugh!" Undead Bone Dragon: "Ouch, ouch, ouch... Help!" Onlookers: "Master!" Chu Xian shook his head repeatedly: "I have no interest in mana. I have never touched mana. Are you right?" The big devil knelt on the ground and shivered, looking aggrievedly at Chu Xian carrying a forty-meter sword on his back...
