Summon the Krieg Cavalry at the Beginning and Travel Across Different Worlds

[Half fan] [Has a female protagonist] [System] [ooc warning] [The protagonist does not know Warhammer] Chen An was summoned to a different world. The summoned Chen An thought it was a cliché plot of the brave princess. Wait, what's going on with this slave crest? Do you call people here just to be slaves? Against Tiangang, when he was about to be branded with the slave emblem, he awakened the Emperor System and summoned the Krieg Death Army. [It is not entirely a Warhammer setting, it is mainly based on Warhammer and some of my own ideas. If the content in it involves OOC, I would like to apologize to all Warhammer fans.
