[No heroine + Ability to gain from killing ghosts + Living King of Hell + Invincible cool writing + Various skills] A strange revival, evil worship in troubled times. Luo Yuan was chased by ghosts as soon as he traveled through time. When he was about to die, he accidentally awakened the strange illustrated system. As long as Luo Yuan kills the ghost, he can light up the corresponding illustrated book. When enough types of illustrations are lit up, Luo Yuan can obtain powerful bonds or skills. Bonds can permanently increase Luo Yuan's attribute values, making him the strongest ghost hunter. Skills can give Luo Yuan extraordinary abilities and the ability to defeat ghosts and gods. From then on, Luo Yuan transformed into a strange nemesis, constantly hunting stronger ghosts. Countless ghosts let out painful wails: "What a ghost in broad daylight, no, it seems like I am the ghost!" "No, don't kill me, I'm a good ghost——" "I'm not human, but you're even less human than me!" "Why is he more like a ghost than a ghost? Ghosts are not as scary as him!" . . . "Ding——" "Congratulations to the host for activating the bond of Treading as Wind, permanently increasing the agility value by 30%." "Ding——" "Congratulations to the host for activating the indestructible bond and permanently increasing the physical constitution by 30%." "Ding——" "Congratulations to the host for activating the skill Shadow Incarnation, which can summon an incarnation with the same attribute value as the host." "Ding——" "Congratulations to the host for activating the skill Zixiao Divine Thunder. This thunder can destroy demons, destroy immortals and kill gods." "Ding——" . . . When Luo Yuan killed thousands of ghosts, increased his attribute values dozens of times, and possessed countless powerful skills, Only then did he realize that he was invincible.
