Tieguan City, the front line of the Kyushu Barrier.
The tide of beasts is approaching, but a secret order to evacuate comes from the city - someone has tampered with the third gate of the north gate, and the shield must be broken once. What is broken is not the city, but human lives and the fate of the country.
Gu Changye, a soldier in the frontier army, "picked up" a piece of the boundary-suppressing soldier in the ordnance scrap metal pile, and awakened the [Leakage System of the Heavens] - he could see the underestimated "leak points" of everything: a suppressing array nail that was thrown into the furnace, a fake repaired crack in the city wall, a new general who was used as cannon fodder... And even the city sacrifice array hidden behind the city lord's palace and the state array courtyard.
He doesn't want to be a hero, he just wants to live.
But when Zhensha suppressed the demon general for a moment, the sword fell, and the north gate was not broken - everyone understood: this city has changed to a law-abiding city.
From guarding a gate, to guarding a city; from picking up military exploits, to picking up the inheritance of all heavens.
When the gap between the borders was half opened and peepers came, Gu Changye realized that what he had picked up was not a bargain, but a road that could penetrate all realms.
