Changqing has always felt that she’s incomparable to Guan Ying in every aspect. Even though she is pretty and has a good family background, this world is nothing more than a world where Princes are more attracted to Cinderellas.

Her first love that she dearly remembers in her heart for years eventually becomes Guan Ying’s current boyfriend and her fiancé is Guan Ying’s ex. He has yet to forget Guan Ying.

A business marriage brings Changqing and Song Chuyi together despite the absence of love.
In public, he is her friend’s ex and in private he is her husband who cannot be publicly–known.
At the hospital, her good friend enjoys her husband’s embrace while she can only act as though he’s a stranger.
At a gala dinner, her good friend hooks her arm around her first love’s arm shyly and she can only smile and give them her blessings.

Dr. Song continues reading his medical books and ignores her. It’s sometimes quite a headache when your wife is too stupid and daft.
Until one day, Changqing realises that there’s really no free lunch in this world…

STAFF NOTE: The author had proven ownership. RighteousEgg is the original author. I have added a pinned comment to the first chapter to show this staff note is legitimate.---Chu Xuan traversed the Mystic Azure Realm and became a demonic cultivator in the Infinite Sect. To cultivate as a demonic cultivator means to plunder the essence of the heavens and earth and seize the quintessence of all things. One has to slaughter countless beings to rise as a supreme demon lord. However, such killing was intolerable under the heavenly Dao of the human race. Consequently, the Infinite Sect was annihilated by the orthodox sects. In desperation, Chu Xuan stumbled upon a Blood Mirror, which allowed him to travel to a post-apocalyptic planet overrun with zombies! He realized that this place was a perfect sanctuary exclusively for demonic cultivators! If he dared to sacrifice a million humans, the heavenly laws would strike him with thunder and burn him to ashes. But if he sacrificed a million zombies, not only would he face no disasters, but he would also be showered with golden blossoms, enveloped in glorious light, and blessed with merits!
