Rotten! Rotten! Rotten!
Yin Li was fired by the company and dumped by her boyfriend. When she woke up, she found that she had traveled to the orc world. He thought that with the brains of modern urbanites, he could make a fortune, but he found that courtship alone was enough to stumped him.
The blond lion orc likes bamboo horses, and the black-haired and yellow-skinned black bear orc has long been engaged… Looking left and right, only the hyena orc who looks exactly like his ex-boyfriend sends a “signal” of love to him.

Adeline Smith's life took a sudden and dangerous turn when her grandmother’s will named her as the sole heir to her massive fortune, leaving her uncle with nothing. But the rules that came with the inheritance only made her a target, as her uncles would stop at nothing to claim what they believed should have been theirs.When one of her uncle’s murderous schemes left her gravely wounded and on the edge of death, she was found by Enzo Laureati, an annoying, yet breathtakingly handsome man. What she did not know was that Enzo was no ordinary man—he was a vampire prince who had abandoned his world and royal duties to live among humans just for fun.The moment he saw Adeline, he knew she was his mate, as his heart that had remained dormant for hundreds of years suddenly began beating. But despite knowing what she meant to him, he felt no love or attachment toward her.Out of curiosity, Enzo saved Adeline’s life and proposed an unusual deal: he would become her fake fiancé, help her expose her uncles for trying to murder her, and secure her inheritance. But he didn't propose this deal because he wanted to help her, but because he was simply bored. Adeline agreed, unaware of the chaos that was about to come her way.At first, their partnership was nothing more than a random deal. Living with Enzo wasn’t easy, as he was infuriatingly confident, annoyingly flirty, and had a knack for driving her crazy with his nonchalant attitude.When Adeline finally discovers who Enzo truly is, will she see him as a monster or the man who had always protected her from her uncles? And will Enzo be able to embrace their mate bond, or will secrets tear them apart?(PS: I'm not sure if one would consider this novel slow burn, but the REAL romance between my MC and ML begins at chapter 74.) Thank you so much for supporting my book!

Dear comrades, masters, priests, masters, fairies, demons, and leaders, welcome to my world and enjoy the supreme pleasure and supreme enjoyment brought by traveling through various worlds (funny laugh).
