No wonder he never enters the harem!”Wait…There seems to be something wrong somewhere… then what did she enter the palace for?!!The new Emperor, Yu Wen Lan, has two secrets.Since his ascension to the throne, he has gradually lost his male functions; yet at the same time, he can read minds.Getting used to seeing their false words and hypocritical faces every day, he grew all the more unfeeling.That was, until one day, he heard a special heart’s voice——[Isn’t this a f*cking waste of natural resources?]Yu Wen Lan paused, narrowing his eyes to look in the direction of a delicately pretty and pure looking girl.[God, for you to make such a handsome hunk unable to XX, doesn’t your conscience hurt at all?] [Is there any way to revive it???] [Ten-fold complete rejuvenation of spring pill, restoration of a man of character pill; if those don’t work, then have you tried return of the yang acupuncture?]Yu Wen Lan, “???”Until she ascended to the position of Empress, Yan Shu also didn’t know how she had jumped unreasonably on the Emperor’s bottom line repeatedly, yet had jumped straight in, becoming the first person to be in his heart.Perhaps, it was just her good luck.
