Having been married for two years, he only takes her as an enemy. He never touches her, and even insult her in front of other women, “Si Wan, you are the most disgusting woman in the world.” Facing his ruthlessness, she decides to leave, “Gong Siming, if you don’t love, just let me go.” But he replied dominantly, “Si Wan, of course I love you.” Si Wan is caught in a trance. And he goes on, “I want to love you tenderly every night.”

A new work from the author of 'My Senior Brother is Too Steady', welcome to enjoy it!-------[Science Fiction Apocalypse Setting + Alone Cultivation Protagonist, Not a Mindless Feel-Good Story]This is a shattered world where human civilization barely gasps for air on a planet ravaged by the Blade Beast catastrophe, the flame of civilization in underground fortresses flickers intermittently, and human elites in space are brewing a final plan to strike back at the Blade Beasts, but the future of humanity is dimly lit by fading stars…“So,”a Mahayana Realm expert, who after cultivating alone for one hundred and twenty-five years failed his tribulation and became a Residual Soul in this 'peculiar' world, sighed deeply as he looked up to the sky:“What the hell does this have to do with me?!”

“You are offering me a marriage of convenience, but princess… there's nothing convenient about me.”

Izabelle had underestimated the fire she thought she was going to play with tonight. But how could she ever have foreseen that the man she had happened to come across with does not play with just a small fire, but a whole inferno?

Excerpt:

“You going through this marriage with me might as well be like you digging your own grave. Because the moment you start to want more from me, I will divorce you. And the moment you break your promise and try to fight me… I will ruin you and break you apart completely. Mercilessly. You will regret ever meeting this devil tonight.” His threat was given in the same soft but cold voice.

But Elle did not even flinch. Her gaze never faltered either. This man was ruthless, and she knew that clearly. His eyes that moment promised nightmares and darkness without any promise of respite.

But no matter what he says now, it would still not change her decision. She truly had no other choice.

“I understand now…” she said quietly, steeling herself. “Since you don't trust that I will keep my word, how about we do this? You prepare the divorce documents beforehand now and I'll sign it. That way, once you decide to divorce me in the future, the papers would already have been signed and there would be no way I can trouble you about it. You would just need to send it to the lawyers and have it notarized.”

A heavy silence reigned before his quiet disbelieving laugh broke the silence.

“I'm at a loss for words, Princess Izabelle.” He looked wickedly amused. But then he started nodding in approval. “Fine, princess. I will marry you.”
