Rakuin no Monshou - Volume 12, Chapter 3: Dairan in Flames

William was but an ordinary man—until fate saw fit to thrust him fifteen years into the past. Yet, this was no mere journey through time; he awoke not in his own flesh, but in that of the third son of Duke Herne, the most formidable noble in the realm.Now, amidst the glittering halls of power, where smiles conceal daggers and honour is but a well-spoken lie, William must navigate a world where commoners are naught but dust beneath the boots of the aristocracy. In this treacherous game of deception and ambition, he must learn quickly—for in the world of the nobility, ignorance is a death sentence----------------------------Hear ye, my loyal readers… From this day onward, updates shall be limited to three chapters per day—no more!Alas, my quill grows weary, and my stockpile of chapters runs thin. The weight of silence presses upon this tale, and my passion falters…I ask but a simple boon—Golden Tickets and a flood of reviews! Shall this humble plea go unanswered?.

A modern-day antihero, who was infamous for his devious acts, dies in an explosion meant to take down a powerful criminal syndicate. Waking up in a world of sword and sorcery, he finds himself possessing a fragile, powerless body with a strange “System” that seems broken. Initially thinking he's doomed, he learns that by pretending to be weak, he can manipulate others into revealing their secrets, granting him abilities they possess. As he rises in power, he discovers that the System was intentionally sabotaged—by none other than his own future self.

As the mad researcher in a tattered white coat activated the self-destruction device, Qin Luo knew that this time, there was no escape.

He was well aware of the destructive power of the self-destruction device.
Even if he is genetically inborn with an independent space, it is impossible to use the power of his space to resolve against such a terrible explosion.

His only end would be a torn space and the crushed bones.

On an unrecognizable earth rampant with zombies and mutant creatures, this end is good.

Death is far better than living…

With a skull splitting headache he opened his eyes to find himself reborn in the year before the apocalypse happened.

Is this a joke!!!
Is this a chance for him to be prepared to combat the apocalypse?
Is God not satisfied with all the bitterness he had went through and would enjoy watching him suffer once more?
