I recommend the fantasy novel "Undying and Eternal Life, Starting from the Eunuch of the Cold Palace". The male protagonist grew up in the Cold Palace with the little mute eunuch. He had a cold personality and was unpredictable. The protagonist had the ability to be immortal, but he still had to face the fate of having his blood drawn and his flesh cut. Endless trouble would always come knocking on his door. I hope you like this fairy's recommendation. Muah ~π
