Reborn as a eunuch, the system tells me to seduce the empress?

[System + Alternate History + Multiple Heroines + Harem + Court + Martial Arts World] Lin Mo is reborn as a eunuch, becoming the head of the Eastern Depot. However, the late emperor dies, and Empress Yu Qingli ascends the throne, dismissing him, the late emperor's confidant, and forcing him to reflect on his actions. But the newly enthroned Empress Yu Qingli finds him utterly displeasing, and on her first day on the throne, she sends him home to reflect again. Just as Lin Mo is about to settle down and enjoy life, a "ding" sound suddenly rings in his mind, activating the Conquest System. [Ding! Congratulations to the host for activating the Conquest System. Please conquer Empress Yu Qingli. Mission reward: Pure Yang Golden Body!] [Ding! Congratulations to the host for repairing his physical defects. You can now undertake the conquest mission to change the fate of the Great Liang Dynasty.] What? Conquest the Empress? The Empress who, even as a princess, wished she could twist his head off? Good heavens! Is this...right?
