You’re the Dragon Emperor? I’m the Emperor of Great Qin!

In a parallel Qin Dynasty, a transmigrator from Earth becomes the emperor of the Qin Empire. As a thousand-year empire, Qin has grown so powerful that its might is almost unimaginable. Ying Xiao, a transmigrator, uses his golden finger to open a Door to other worlds! When the Qin Empire's steel legions appear in other worlds, and its Black Dragon Banner flies across the sky: God of another world: “I am willing to submit to Qin!” Pope of another world: “Noble Emperor of Qin, let me kiss your shoes.” Saintess of another world: “I am willing to warm the Emperor of Qin's bed!” Gods? Ghosts? Monsters? Demons? As Qin's iron cavalry descends upon the Myriad Worlds, the Qin Black Dragon Banner flies across them all, following in the wake of its armies! Ying Xiao: “Before Qin, even gods can be slaughtered. As long as they have health bars, Qin won't hesitate to kill them all!!!”
