My Muscle System in the Mage World - Chapter 383 Fourth Dimension

There was once a hero.

Unique black hair. Excellent eyes. Contrary to his delicate features, he who had abnormal strength was called the Otherworldy Hero.

At the hero’s long adventure (up to the point where his wooden sword that had been kindly granted to him by the king was replaced by the holy sword blessed by the holy maiden) he saved the prince that had been kidnapped by the demon king, and so the kingdom was swept by worry.

The hero’s strength that could fell the demon king was deemed too dangerous to leave unrestrained.

One advisor spoke up. Why not marry him to royalty?

The king thought that was a viable option. Family, to an alien from another world would be the best of chains. There was one problem. The king was abundantly blessed with sons and had princes galore, but not a single daughter.

Ho, and it wasn’t like I could marry off two boys.

At a burst of inspiration the king slapped his knee.

That was it!

You just had to turn a prince into a princess!

And so the hero ended up in a position to be marrying a man.

This story, is a tale of the aforementioned otherworldly hero, and his bride, the former-prince-now-princess and their ridiculously hilarious marriage.

Due to the machination of her boyfriend (Yi Jinxi) and “bestie” (Zhong Yi) , Xu Luosang who used to be a noble lady of a rich family was reduced to hiding her identity in order to rise up again. Her fiance put her father in jail and all that love turned to hate. So she lies about her age, hides her beauty and starts working as a carer in order to regain her power so she could save her father.

Our story begins with her nursing Nian Junting, a high-handed and narcissistic president, who suffered an accident and is unable to move and also unable to get it up. Being a man-child, the words he says are always the opposite of what the other party wants.

She thought their relationship was nothing more than a deal, so she left continuing her plans in her revenge, but time proved that he really loved her. He kept pestering her shamelesly, even obtaing a marriage certificate. His righteosness and fairness charmed her in time…..but will he make her fall in love again?

His sister: “Luosang must have reaped a significant amount of bad karma in her past lives to have been fancied by her brother.”

Him: “If I make Zhong Yi fall into the water every day, will you kiss me and feed me every day?”

Luosang’s mouth corners twitched slightly. ‘Really? Are you jealous of a dog?’
