MTL - The Roots of Manga - Chapter 43 expression of admiration

Waking up, Kim Hajin finds himself in a familiar world but an unfamiliar body.

She always knew there was a woman hidden in his heart, so when that woman appeared, she obediently withdrew. However, unexpectedly, he abandoned his 'beloved' and instead frequently invited her.“Mr. Fu, didn't you say there was a contract to discuss?” He pressed her against the cold wall, continuously approaching: “If you were a bit uglier, perhaps I would want to talk contracts and drink tea with you, but you're so beautiful, I only want to talk love with you.”To him, Qiao Mo was like his most cherished treasure, and whenever others looked at her, he felt they were trying to steal her.

She died in her prime as the Queen of Song.

After being reincarnated, she becomes a simple trainee.

Losing her former glory? It doesn’t matter—no one can compete with her voice as a beautiful singer.

Mocked by her lowly birth? It doesn’t matter—her true identity is enough to make the whole world tremble.

She owes huge debts? It doesn’t matter…

A powerful boss once whispered to her, “Your debt will disappear if you become my woman.”

But the proud her would reply, “I’m sorry. I would sell my art, but not myself.”

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”.
