Beilin's iron hooves crushed the border town, and the Yunqi Kingdom was in a state of turmoil. The factions in the court continued to fight, the peace faction colluded with foreign enemies, and the war faction was isolated and helpless. Refugees spread all over the border, and people died of hunger everywhere. Yanmen Pass in the north had long been an isolated city.
Lu Zhaoyan, the captain of a poor family, led the remnants of his troops to cover the retreat of the people, vowing to defend every inch of the mountains and rivers amidst the light of swords and shadows; the fugitive counselor Su Qingci, armed with secret technique drawings and irrefutable evidence of collusion with the enemy, searched for an opportunity to break the situation in a desperate situation.
Xie Heng, who was demoted as a civil servant, used his pen as a sword in the court, and died alone to defend his loyalty; the iron-blooded general Yan Jinghan, with his blood as an ally at the top of Yanmen City, fought bloody battles to protect the peace of his family and country.
Four people come from all over the world and meet each other in troubled times: he guards the battlefield, she plans the overall situation; he fights traitors and sycophants, and he controls the border. The two pairs of fetters run in both directions. There is no love between children, only the life and death of "you defend the country, and I will protect you"; there are no hidden and restrained feelings, only the magnanimity of "even if we go to hell together, we will not bear each other down".
In the game between the four countries, secret techniques are revealed, and the secrets at the core of the continent are revealed - should we cede territory and seek peace and survive, or should we fight side by side and change our fate?
When a humble school captain counterattacks and becomes a marshal, when an escaped orphan transforms into a national advisor, when a demoted civil servant takes charge of the government, when an unjust general regains military power, the four of them will finally join hands to return the war-torn continent to a peaceful and prosperous age!
