Venshiro, a young ronin bound to the Black Vein Blade, is hunted by clans who would kill for the curse he carries. Every time he draws the sword, it takes something from him—his memories, his soul. But the blade remembers everything.And now, it wants more.

“Young man… if you could go back in time, what period would you like to be in?”

“You need a legal wife. I need a husband in name. I can get him to work with me!”

“You … What are you doing! ” Jin Yan gripped the thin blanket tightly, her face was full of caution. Why did this man appear in her room late at night?!

He stepped forward with a faint smile on his lips, “Of course it's what a husband and wife should do.”

After being so long suppressed, she was furious.

The man panted heavily. With a bewitching voice, he said, “Alright, I’ll go out to clean up. I don’t need anything but you!”
