Empress, You Mustn’t! I Am the Chancellor of the Qiu Kingdom

[Female-Dominated World + Empress + Possessiveness + Alternate Setting + No System + Forced Love + Yandere]

After fulfilling the late emperor's final wish, Lin Han was ready to retire after a job well done. But the empress he had helped install on the throne imprisoned him, launching him on an entirely different journey...

The empress he had enthroned: “Didn't you say I was useless? Then I'll show you exactly how useless I am!”

The deposed emperor, demoted to King Qian: “Hahaha, Chancellor Lin, look at you now! If you want my help, sure...”

The empress of an enemy nation: “Well, well, Chancellor Lin has arrived.”

The Demon Emperor pursed her lips. “This human is pretty good. He'd suit me.”

The leaders of the various sects of the Heaven-Covering Cult: “Lin Han, we want to grow stronger. We need your help.”
