I am Lorne, a "bone tattooer" cursed by fate. My hands can use the bones of the deceased as ink and the fire of the soul as a pen to carve out mysterious "contracts of the dead"! With every stroke of the tattoo, vitality flows away like a tide. The empire wanted to turn me into a war machine and launched an endless pursuit of me. However, during a desperate escape, I accidentally broke into an ancient sealed tomb, where I discovered the remains of the "Empress of the Undead" who had been sleeping for thousands of years! What's even more astonishing is that her bones actually have unfinished bone marks left by her master! In order to survive, I made a desperate move and completed the forbidden bone pattern at the cost of my own life, and unexpectedly established a "master-servant contract" with the sleeping undead empress! I became the only "master" of the Undead Empress! But the price of the contract is that the empress will take my life every time she wakes up! The empire, the undead monarch, the mysterious forces... All forces covet the power of the empress, and they are eyeing me as the "master"! I will use my life as a bet and my bones as evidence. In this troubled world, I will live or die together with my undead empress, and finally carve out my undead empire!
