Soul Travels to Another World: Becoming the Eldest Son of a Fallen Baron

The military doctor Wang Zheng died on the battlefield, and when he opened his eyes again, he became the most miserable eldest son of a baron in another world. This is a world where emotion is magic, and the boundaries of protection determine the strength of power. Nobles protect their bloodline, strong men make contracts, and he chose a road that no one has ever walked before—— Use systems to create protection beyond blood ties. Injury tickets, triage, standardized procedures... He turned the systematic thinking of field hospitals into the "eighth magic" of this world. In the desperate northern region where monsters are around and a cold wave is approaching, starting from a dilapidated medical inn, we establish order, connect people's hearts, and fight against the cold law of the jungle. When the shadow of the Iceback Bear and the suppression of the nobles came at the same time, the sword he wielded was not his personal power, but the condensed will of the entire system. This is the destination of the empty nest soul, and it is also the final blueprint for the continuation of civilization on an isolated island.
