….For being mistaken for someone else.

A premeditated car accident almost cost Lu Jinghan his life, but fortunately, Doctor Han saved him.Later, the old master of the Lu Family said with delight, “The life-saving grace of Doctor Han cannot be thanked with words; it's better to let my grandson offer himself in gratitude.”“Old man, that's enough.” A deep voice came from behind, belonging to Lu Jinghan.Han Xi also felt as if she had been struck by lightning. She's a doctor; healing and saving people is her duty and doesn't deserve such... generous reward....Later, Doctor Han became the person Mr. Lu cherished in his heart.Mr. Lu had a smile on his lips, a smile as sweet as nectar: “Let's have a child, then we'll be a family of three.”“Two, I want both a boy and a girl.”“No, just one.”“Why?”Mr. Lu gazed lovingly at his Mrs. Lu: “It's too painful to have a child, one is enough.”What to do, it seems Doctor Han wants to pounce on her Mr. Lu right now.

When natural disasters ran rampant, with extreme cold and storms spreading endlessly…When the world mutated, zombies surged like tides, and eerie horrors emerged…When the apocalypse descended, massive Devouring Abysses hundreds of kilometers in diameter began appearing around the globe…When people looked up at the atmospheric cloud layers and saw the slowly emerging corpse of a colossal evil god…From that day, people began to notice that daylight was arriving later and later, until the sun no longer rose, plunging the world into an unending polar night.For survival, on that day, the Apocalypse Radio made its final broadcast to the world:“Everyone, flee eastward—escape to dawn!”…Lin Xian awakened the [Mechanical Heart] ability. He could devour machinery to gain various mysterious skills, scan machines to obtain blueprints for manufacturing, and even use his thoughts to achieve unified control of different machines.Thus, he found a 200-ton heavy gas-powered locomotive, towing specially modified storage, planting, production, medical, and living carriages, and embarked on a 320,000-kilometer journey along the planetary orbital rail—charging eastward toward the dawn!

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”.
