MTL - Plane Source Code - Chapter 4 Infected with HGV virus

In his old world, Aiden Ferith was a peerless war hero—feared by nations, revered by millions. Through years of brutal cultivation, he reached heights others only dreamed of. But glory turned to ash when his most trusted disciple drove a blade through his heart, shattering his empire and his soul.That should have been the end.But fate had other plans.Reborn in a world ruled by magic, where mages manipulate elements and battle with dazzling spells, Aiden awakens in the body of a seemingly average boy named Logan Smith. Here, cultivation is unheard of—dismissed as a myth, or worse, a joke.But what they don’t understand will be their undoing.Armed with ancient cultivation techniques that bypass the limitations of magic, Logan begins to carve a path that defies the laws of this new realm. Stronger, faster, and more resilient than any mage, he’s not here to play by their rules.He’s here to break them.Betrayed once.Stripped of everything.This time, he’s not fighting for a kingdom—He’s here to live life on his own terms—to protect those he loves, and finally, to live for himself.

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”.
