I Consummated My Marriage with My Wife, and the System Said I Was Suppressing the Empress?

Traveling across the Taixuan Continent, Fang Qingyuan's magic skills backfired, requiring the reconciliation of yin and yang. "Ding! Congratulations to the host for successfully suppressing the Empress. Reward the Demon Emperor's Kung Fu: Blood Skull Swallowing Demon Kung Fu!" ? Fang Qingyuan looked at his ordinary beauty with a confused look on his face? "Ding! Congratulations to the host, you successfully killed the son of the emperor, the soul-killing gun!" Uh... Fang Qingyuan just killed a qi-training monk from a human dynasty? Why do you say he is the son of the Great Emperor? "Ding! Congratulations to the host, you successfully captured the Heaven-Swallowing Demon Dynasty and ascended the throne as the Heaven-Swallowing Demon Emperor!" Is this system crazy? Fang Qingyuan killed a young emperor in order to improve his cultivation, so he named himself the Heaven-Swallowing Demon Emperor? "Ding! Fire crystal dragon veins have been found at the junction of the Heaven-Devouring Demon City and the Great Flame Immortal Dynasty. A large number of top-grade fire-type spiritual stones can be obtained. Your Majesty, please send troops to fight for it!" Fang Qingyuan looked at the volcanic rocks brought back by his men. This system is a joke...
