Valkyrie Lord System

Hunting with flags, leaping horses and whips, killing in troubled times, stopping war with war. No matter how many conspiracies you devise, you will never be able to stop my millions of cavalry. No matter how unparalleled your god of war is, you can't stop my tiger and wolf masters. Let's see how Leng Xinghe, who traveled through time and became the concubine of a wealthy family, uses the power of the system to stir up troubled times, dominate the world, and conquer other worlds. Ps: The original name of this book is "Starting with a Valkyrie", so there is no need to ask why the heroine is better than the protagonist.
