I'm Sure to Die Within Three Episodes

Blurb: Lin You transmigrates into a cannon-fodder husband of the tyrant in a female-led power fantasy. The reborn heroine has already entered the rear court, while the tyrant has yet to ascend the throne. Lin You, the tyrant's official wife and a cannon-fodder character, is about to "die of illness" to make way for the heroine, perfectly fulfilling his role before being killed off. Lin You figures that with his intelligence being what it is, he might as well give up on getting anywhere. The heroine can do whatever she wants in this palace intrigue story. Once he's drunk Meng Po's soup, he'll be a new man. System: [Your cheat has been activated. From now on, you are immune to all poisons, immortal, and indestructible. We wish you good health as you cough up blood!] Lin You pops right back up like a lazy fish. Looks like I can still make it! After that, Lin You repeatedly gets to the food first, takes a bowl whenever there's poison, and taste-tests dishes for the tyrant. When framed, Lin You proves his innocence by risking his life, spilling blood and teetering on the brink of death time and again. When shielding the tyrant from a bullet, he's just as unhesitating, charging ahead. The future tyrant watches, utterly dumbfounded. Tyrant: He loves me so much!!! The tyrant hands over the money he'd been withholding and adds another investment: "Take it. If your business loses money, I'll cover it!" The tyrant puts him in charge of the family estate. The tyrant sends the women in the rear court away. The tyrant sends the heroine back to her old flame. The tyrant topples the old emperor. The tyrant carries Lin You back to his room. Tyrant: "I'm going to ascend the throne. Will you be my empress?" Lin You: "?" * Lin You once thought that if he served the tyrant well and made enough money, he could follow Fan Li's example, retire, and save his own skin. That is, until a thick stack of land deeds, house deeds, and sale contracts is slapped onto the table. The tyrant angrily comes looking for him. "What is all this?" Obviously, it's the fine farmland, mansions, maids, and retirement funds belonging to Lin You. He smiles. "Come on, everyone's entitled to a little private stash!" The tyrant cries in frustration. "I don't have one. I gave everything to you!" Reader's guide: - A seemingly sickly, weak recipient who coughs up blood at any moment X a poor, doglike attacker who's known for being lecherous but has never actually gotten any - The attacker has never had a relationship with any of the women in his rear court. They're all just there as a cover... - Logic has left the building. The recipient has a painless cheat that leaves him permanently at critical health without killing him. His health is unlimited, and he'll never run out of blood to cough up. [The title and blurb are provisional.
