My Checkpoint System Turned Me Into The Godfather of Humanity - Chapter 458

Zuo Chengan was thrown into a brutal survival game, only to awaken its sole god-tier skill: The Eye of Truth.From that moment, he began to see the game—and the world—for what they truly were.A broken branch lying by the roadside?Ordinary players: “Just a useless stick. Toss it aside!”Zuo Chengan: “A hidden NPC is offering a feast of rare delicacies.”A suspicious dish placed before the group?Ordinary players: “Don’t touch it! It’s probably poisoned!”Zuo Chengan: “Completely safe. And utterly delicious.”A monstrous creature blocking their path?Ordinary players: “Terrifying! Avoid it at all costs!”Zuo Chengan: Silently studies its hidden weakness.What began as a game to push humanity toward evolution revealed itself to be something far more sinister—a trap, a scheme of ruthless exploitation.The desperate battles fought in the game’s dungeons were nothing but a spectacle, staged for the amusement of another world.With his all-seeing Eye of Truth, Zuo Chengan ascended through the 12 Heavenly Trials, dismantling the web of lies spun by the false gods. His piercing sight exposed the malicious truths behind the game.Standing at the summit, blade in hand, he declared, “I will cut through this endless night, tearing apart the shadows of chaos to reveal the light of truth. Let the world see reality once more!”

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?
