MTL - Crossing Over I Became a Married Peasant Woman - ~ been tried

An ordinary office worker, bound by routine and indifferent to fantasy, finds an unexpected spark in his vibrant senior colleague. Their quiet connection grows through late-night conversations and shared meals—until a sudden accident turns a mundane life into something else entirely. In the stillness that follows, a new story begins.---Disclaimer:English is not my first language, so please forgive any grammatical or spelling mistakes.

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”.
