Sand Mage of the Burnt Desert - Chapter 218

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”.

The sky was painted gray forever. The light of the sun was restrained. The darkness of the night was deeper than ever. At such a time, he belonged to a class people didn’t even recognize as ’human’. He was at the bottom of the social stratum, a slave. And when his only family was taken away from him... he no longer had a purpose in life. Yet, he clung to life because of his promise. And he set an impossible goal for himself, just so he’d have an excuse to live. When he finally reached a place he never expected to be, in pursuit of a purpose he expected to fail and die miserably trying to fulfill... he awoke to a night that would change his entire life. He was an insignificant fly, a mere speck in the destruction of the Empire. But he... survived. And, despite being a slave, he gained the blessing of a king. Or rather, the curse...

Xiao Luo and his girlfriend had been in love with each other for four years when she proposed a break up. Because of this, Xiao Luo sped his car in the night and ended up in a car accident. But it was a blessing in disguise as he unexpectedly fused with a high tech system that originated from a universe hundreds of billions of light years away. From this moment on, the entire world started to run amok.....

People were jealous of her. An orphan married into a wealthy family and had a handsome, gentle, and wealthy husband.Little did they know, they slept in the same bed but had different dreams, and seldom communicated.People think his husband is perfect, but only she knows that he calls out other women's names in his dreams.Even though she gave birth to twins, she didn't touch him.So she filed for divorce.Finding his wife abandoning her children and property just to be separated from him, he suddenly felt anxious.When he returned home, he found only the hungry children waiting to be fed, and the bed was also so cold. A luxurious villa without a wife is just a pile of steel and concrete. He suddenly realized that he had already fallen in love with her, but she had become his unattainable heiress.She said, “Sir, you have to queue up to chase me. You'd better go back and take care of your children.”He held his two children and smiled, “The children are too young to live without their mother. Let's give them back to you.”When the servant brought the children's luggage into the house, he emerged from a huge cardboard box and said, “I am the children's doll, and you can also think of me as an intelligent robot - with a complimentary warm bed service.”“..”
