After the Marriage Partner Sacrificed Himself to Me

I am cursed by the abyss. I'm dying. My boss thought that the waste could be reused, so he threw me to a neighboring country for marriage - they were planning to steal the treasure of the neighboring country. The boss said: If the mission fails, I will be the scapegoat. If the mission is successful, I will be the one taking the blame. In short, it is a dead end. I think this way of death is OK, at least it doesn't waste my final value. I felt very sorry for my marriage partner from the beginning to the end. As a tool man who is more of a tool man than me, his only value is to hold the key to unlock the treasure, which is only one-third. For this third of the key, he was tortured to death, and it seemed that he would not live much longer. In our plan, it doesn't matter whether he dies or not. But since I was definitely going to die, I decided to use my remaining value. I used my own blood to buy his life. As a result, my sickly marriage partner became an abyss lord as soon as his health was full. ——And I completed the sacrificial ceremony by mistake and successfully sacrificed myself to him. It's better now. Alive, I am the legal partner of my marriage partner. Dead, I am a fresh sacrifice to my marriage partner. Fortunately, I was reborn, at the age of fourteen, with no curse, no mission, and no marriage partner. I decided—— First, let's go get my former marriage partner who is seriously injured at the moment. The beautiful woman is in an unstable mental state and is attacked by X in a stable mood.
