Yue Yan Gets kidnapped by the goddess on his sweet night with his girlfriend. She asks him to help her on a mission against the XieLong temple but he turns her down.

Later, some mysteries reveal their past and Yue Yan agrees to help her in order to meet his Bing'er again who has also been sent to the new world.

When he transmigrates into the body of Meng Long, he finds out he has a special Physique, the Supreme Yang body that stops his growth in Cultivation unless he Dual-Cultivates with a woman.

Yue Yan's new family had mistreated his predecessor Meng Long so he decides to leave the clan to embark on a new path with his beautiful concubine Xue Rou.

Join Yue Yan AKA Meng Long, in his Journey to reach the pinnacle of the world.

Siyu transmigrated into a manhua and became the male lead’s half-sister. The sister had a sickly fragile body, one that couldn’t even withstand a gust of wind. It’s a pity that her heart was so vicious. Over and over, she tried to kill the male and female lead. Until finally she was hated by all, deserted by everyone close, cursed by people, and died miserably alone in the rain one night.

Now the question was: how could she stay alive in peace as a sickly beautiful lady who always vomits blood for no reason and could drop dead at any time? Fortunately, Siyu soon discovered that she could see another person’s luck. So, as long as other people around her had better luck than hers, she could rely on their blessings to extend her life.

As for her….. Siyu looked into the mirror. No matter how she looked at it, the person in the mirror looked like she would die early. It’s not an exaggeration. If you’re talking about bad luck, then everyone else was trash. The wave was stable; no matter how crazy she played, she wouldn’t die! (～￣▽￣)～

Until she came across a great god who was feared by everybody—

Siyu: “Don’t, don’t come near me QAQ”.

Fifth Master Lu smiled gently whilst the beads on his hand were shattered into pieces, “ Run away once more, and I’ll break your leg.”

When other people experience a body transformation, it is inevitably either male to female or female to male.

Me? I wake up to find myself transformed into two different bodies.

Both a male body and a female body, one conscience operating two bodies, all sorts of embarrassing moments.

Walking together normally makes other people think that I am sweethearts with my other-self, such sadness.

Also, the entire business of a hero rescuing the beautiful maiden, I call Bull.

I get slashed by a sword and my female body gets abducted, and he wants me to thank him?!?! Can it be less of a tragedy?
