Ling Ye once traveled to the troubled frontier, carrying the iron-blooded memory of his previous life, but became a death row prisoner in the enemy camp. When the cold blade pressed against his neck, he held the blade backwards and blood spattered three feet, alerting Cui Luming, the cold-faced general guarding the border. This man held the tiger talisman in his hand and said nothing, but when his life was hanging by a thread, he drew his sword to protect him. Ling Ye didn't know that Cui Luming had been waiting for him for seven full years - that year when the war burned the city, the boy he saved had the same pair of blood-stained but unbroken eyes now. Under the blade, the old covenant is rekindled, the feud between the two countries remains unresolved, and the bloody journey of the two people from being strangers to relying on each other for life and death.
