After renaming himself and escaping his family's initial grasp, Ascathon realizes that his freedom is temporary without physical security. He uses the teleportation gates to reach the freezing northern capital of Norfolk, determined to secure a sovereign base. Facing two guards who refuse him entry to the Jarl's hall, Ascathon bypasses them by using telekinesis to ring a giant golden summoning bell. Inside, he presents a map of Sarn-Valley to the obese Jarl and tosses a pouch containing one thousand platinum coins onto the desk. He negotiates a clever contract where he gets full rights to the desolate land, but if his noble line dies out, the land reverts to the Jarl. This bet appeals to the Jarl's greed, as he assumes Ascathon will soon be killed by assassins. Armed with his new deed of nobility, Ascathon seeks out the Icewolfs, the most elite mercenary guild in the city. He insults their leader, Den, to test their strength, resulting in a brutal bar fight where Ascathon uses stone-skin magic to endure a severe beating. The fight is interrupted when ten hooded assassins from his past-life enemies break into the tavern and throw fireballs. The mercenaries transform into giant, magic-resistant werewolves and tear the assassins apart. Watching his guild house burn down, Den is furious, but Ascathon offers another thousand platinum coins to hire all one hundred werewolves as permanent bodyguards. This critical decision provides Ascathon with an indestructible shield against the impending waves of family assassins, allowing him to safely travel to his new territory of Sarn-Valley to begin his technological revolution.

Arriving in Sarn-Valley, Ascathon immediately overthrows the corrupt, lazy council of elders, keeping only the three competent administrators to run his new government. He injects two hundred platinum coins into the local treasury, ordering the construction of schools, blacksmiths, and basic infrastructure, while enforcing a strict tax on the mountain passes. His peaceful development is interrupted when his former school rival, Celestial Jasmine, is captured by a slave-trading raid and put up for auction in the hot southern nation of the Jamaian Union. Ascathon travels to the slave market with his friend Kane and discovers his own eight-year-old sister, Violetta, and Celestial on the auction block. When a wealthy, golden-masked noble bids a platinum coin for Celestial, Ascathon outbids him with an astronomical offer of one hundred platinum. The golden-masked noble challenges him to a duel to the death, igniting his sword with blue fire. Ascathon disintegrates a wooden chair into shrapnel with wind magic, repels the fire with a cushion of circulating air, and stabs his bare, mana-infused hand directly through the noble's chest to rip out his beating heart. He heals his own charred flesh instantly using silent healing magic and claims the slaves as his property. Before leaving, Ascathon leaves a timed fire-tornado spell in a washbasin, which burns the entire slave market to the ground and kills the prime minister's son. This violent rescue forces Celestial to realize that Ascathon is not the monster her parents claimed, setting up an uneasy alliance between the two reincarnated souls as they return to Sarn-Valley to face the consequences of their actions.

As Sarn-Valley grows into an industrial stronghold with greenhouses, blast furnaces, and clean energy, the global balance of power begins to shatter. The aggressive Phenex Empire, led by its own immortal Empress, launches a naval invasion against Sarn-Valley, sending five massive warships up the narrow fjord. Ascathon refuses to use traditional magic, choosing instead to test his new military inventions, which are camouflaged watchtowers armed with mana-powered railguns operated by commoner soldiers. The rapid, silent bombardment of metal slugs easily penetrates the defensive barriers of the Phenex ships, sinking four of them in a single minute and proving that technology can defeat elite magicians. Amidst this victory, Celestial goes into labor and gives birth to their daughter, Seraphine, who is also a reincarnated soul with memories of a thousand past lives. The family's peace is shattered when the academy's inquisition and Ascathon's former family launch a joint invasion on the ground. Ascathon intercepts the army at the mountain passes, but his flying flagship is sabotaged by a mysterious, long-eared divine force that overloads his mana core. Ascathon crashes his ship directly into the enemy army, compressing the overloaded mana into a solid blue crystal and surviving the impact. He emerges from the wreckage to confront his father, Tendril, and his brothers. Ascathon uses a terrifying shadow spell to force his father into the burning wreckage, kills his brother Andrus in self-defense, and is rescued by Celestial before the remaining poison can paralyze him. This total annihilation of the invading army establishes Sarn-Valley as an unstoppable military power, forcing the world's hidden gods to realize that their cosmic game is spinning out of control.
