A wedding took place, and the richest man of Shencheng married a woman notorious for her bad reputation.Ning Guiwan was known among the upper class as a calamity—tormenting her sisters, causing her mother's death, leading an unseemly private life, despised by her father, and cast abroad to fend for herself.Four years later, she returned and directly took hold of Shencheng's most esteemed man's arm to enter into marriage, leaving the whole city in shock.However, amidst the doubts, Ning Guiwan presented a post-marriage agreement to Quan Yu, with the last clause reading: beyond cooperation, there shall be no involvement with each other.Quan Yu pinched the girl's waist, his lips curving into a smile, “You start the game, but I decide how to play it.”……Everyone said that Ning Guiwan, relying on the favor of the Quan Family's old matriarch, forced Quan Yu to marry her; otherwise, how could a man with such sound principles fancy a woman not only beneath his station but also with a scandalous past?But those who knew the truth shook their heads. Sound principles? Nonexistent. To get his wife, Mr. Quan resorted to all kinds of dirty tricks, even deceiving the old matriarch, yet Mrs. Quan, with her cold exterior and hard heart, married him but refused to love him.Until one day, Mr. Quan accidentally got injured, causing Mrs. Quan to frown.Then—“It's terrible, Mrs. Quan, the master has injured his arm, please come back and see him!”“It's terrible, Mrs. Quan, the master has injured his leg, please come back and see him!”“It's terrible, Mrs. Quan, the master...”“What happened again?”“The master says he's sick, please come back and see him!”“What sickness?”“The master says it's... lovesickness...”“……”[A pampering story, sweet to the extreme]

In this world, orphans or just anyone without any hope for this world can apply to become a “walking target”. Their sole purpose is to be a practicing dummy for the students of the sect who train to become “Demon Hunters”. These students need “walking targets” to test their training on living, walking beings of flesh and blood.
In exchange, they will be provided with food & shelter.
Their existence value is lower than a slave, but if they manage to survive a few years they can receive a life long pension.

Xiao Han is such a “walking target”. One time he witnessed a powerful Demon Hunter disposing a demon. When the demon died, a fragment of the demon that managed to escape entered Xiao Han’s heart. No one saw that, and even Xiao Han himself only felt some discomfort for an instant.

But that thing in his heart soon gave Xiao Han visions, and the first one is of a cultivation method which allows Xiao Han to absorb damage to enhance his body. A perfect cultivation method for a “walking target”.
