Forced Into an Arranged Marriage, I Ended Up Becoming an Immortal Emperor

[System + invincible hero + lots of beauties + female emperor + power fantasy + never loses a fight] Zhou Du transmigrates into the Great Xia Dynasty and fights to the death for the empire, only to have his dantian shattered and his cultivation destroyed. His cousin steals his battle honors, and the princess Yue Lan, promised to him in marriage, is replaced by Princess Fengwu, who's in a coma! But Zhou Du binds himself to the Immortal Fate System. As long as he wins the favor of someone with immortal fate, he becomes invincible! And the first person with immortal fate is none other than his betrothed, Princess Fengwu. Her favor instantly maxes out, and his cultivation skyrockets. His dantian is shattered? An Immortal Palace will take its place, and he'll cultivate an immortal body! Immortals from the heavens attack? With a peach branch in hand, he'll cut them all down! He never loses, he's called invincible, and he's never lost a fight! My name is Jiang Fengwu. I am the reincarnation of an unrivaled female emperor, and I fell into a deep sleep to recover my cultivation. Listening to Zhou Du prattle on beside me, I sneered. "The female emperor stands supreme. Why would I need to rely on a man?" Later, Jiang Fengwu had to admit he was irresistible and wished she could cling to Zhou Du day and night. The day Jiang Fengwu recovered her cultivation, she stormed the palace with a sword, only to find Zhou Du sitting on the throne. "Husband, who put that imperial robe on you?" Zhou Du instantly entered his immortal form. "Fengwu, you can sit on our throne. So what's wrong with your husband taking a turn?" Jiang Fengwu: "How are you even better at fighting than I am, Husband?" Princess Yue Lan came running over in tears. "Zhou Du, I'm a better match for you than Jiang Fengwu!" Zhou Du: "What kind of demon are you? How dare you possess a princess and sow discord? Take this spear!" The blurb won't pass review, so head to the main story!
