Transmigration, vampires, underworld enforcers, the Underworld, the Heavenly Court, the Demon Court, interstellar worlds, and technology.
Yun Ziyuan transmigrates to a strange otherworld and becomes an underworld enforcer. Half a year ago, he fell through a rift in space and time, losing all his memories...
When an advanced civilization descends upon the otherworld, you'll see Sun Wukong battle a space carrier, the Bodhisattva Ksitigarbha take on a Gundam, the Five Ghost Emperors carry the Gates of the Underworld around wherever they go, and countless reclusive masters unite to fight alien civilization. So what if their technology is powerful? Cultivating demonic or immortal arts is the Way! The worldbuilding is vast: the Buddha will be fired up, the King of Hell will exclaim that it's awesome, and even the goddess Nuwa will give it a like.
Come along and witness Yun Ziyuan's growth...
