(Chongwen, strong men and women) On the wedding day, her husband stabbed the knife of betrayal into her heart with his own hands,

“Did you know? The person who saved you back then was not me, but the sick child who first asked Tian!”

Only then did she know that she had been in love with the wrong person!
In the raging fire, she vowed like a ghost:

“Sikong Hao, I swear to God that if there is an afterlife, I will seize your imperial power and destroy your country!”

Opening her eyes again, she found that she was actually reborn on the body of Bei Gongxue, the number one waste material of the Bei Gong family.

Clenching her fists, she hooked her lips and sneered: This time, she will not be blind and love others wrongly.

To the person who harmed her, she directly tramples on it, and to the person who loves her, she swears to protect her to the death, and she will never let him suffer any more grievances!

When the waste material turns over, when the sick king no longer hides his strength, their love is destined to be vigorous, so that the world can only look up!

But when the world said that Princess Xuan was arrogant and ruthless, and her wrist was bloody, he said: “My love is the biggest capital of your arrogance and domineering!”

18 years have passed since I was born as Allen, the eldest son of an earl in this world, while still retaining my memories of the present world. This world is peaceful and a stable society. The only extraordinary thing is that I was reincarnated into a world that is lenient on the existence of concubines. I selected a silver-haired maid as a sex slave and second wife candidate from among 10 candidates after a strict fellatio practical exam. I then lived an erotic life at home and at school as an attendant, but my reincarnated life is so fulfilling that I'm worried it will explode, as my busty childhood friend, a noble girl who was unsuccessful, ran for the third wife candidate, and my stepmother, who was my virgin partner, was sold off.
