Reversal - Chapter 17 Future

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”.

Zhen Lang and Gu Jing have been childhood enemies for over twenty years and pretend best friends in front of their parents. Zhen Lang and Gu Jing’s source of happiness is defaming their enemy (each other) at every opportunity, dreading the day their parents’ match-making dream comes true.

In humanity’s final war against the Demon Lord, the strongest heroes fell—not by the enemy’s hand, but by their own, twisted into madness by a cruel illusion. Betrayal. Bloodshed. Despair… and then, silence.Only one person remained: Riley—the weakest warrior of them all. Powerless. Ignored. Forgotten.But he saw through the Demon Lord’s deception. The tyrant was on the brink of death—so weak even a fly could’ve finished him off.And Riley did just that, drawing every last ounce of strength to bite off the demon’s head.Victory? Not quite. A final, desperate strike from the Demon Lord pierced him from behind, killing him instantly.But fate wasn’t done with him yet.Riley awoke ten years in the past—when the online game [Apocalypse] was launched. Before demons descended. Before monsters overran the world.And this time, he wasn’t starting from nothing. He had a decade of experience—and a second chance.Even more shocking, he didn’t awaken his old D-rank Strength Boost talent. This time, he received something far more terrifying: an SSS-Rank Gluttony talent!He could now devour anything—monsters, items, talents, even traits—and gain their power.Ding![You have devoured: Iron Fang Wolf][Acquired: +4 Strength, +2 Agility, Skill: Bite (F-rank)][You have devoured: Goblin ShamanAcquired: +8 Intelligence, Skill: Mana Bolt (E-rank), Talent: Minor Spellcasting Efficiency][You have devoured: Flaming Salamander Drake][Acquired: +22 Endurance, Trait: Dragon’s Resilience, Skill: Flame Breath (C-rank)]Now, there is no demon, no god, no monster who will stand in his way.

I got transmigrated into a game I’ve never seen before.

I thought it was a top-notch RPG and spent 30 years on it.

I retired as a war hero and planned to spend my remaining time leisurely.

But it turns out, it was an academy story?
