Everyone knows that Emperor Qing Ling Jin has an immortal sword.
The name of the sword is Xuan Ying, it is obedient and flawless.
Ling Jin uses him but also doubts him. It wasn't until he coughed up blood and fainted that he realized the truth about "same fate" - every time the Shadow Guard died, he was silently regicide.
He locked Xuan Ying into a golden cage, with a world-destroying madness in his eyes: "Your life belongs to me, you are not allowed to die!"
Xuan Ying lowered his head in the cage, grinding his lifelong loyalty into ashes. It turns out that every time he "shows loyalty", he is slowing down his king.
A war broke out at the border, and the enemy asked him to "sacrifice heaven and apologize." Ling Jin tore up the letter and protected him behind him in front of thousands of troops:
"I would rather burn my people with my own hands than let others have their turn!"
At that moment, Xuan Ying saw clearly the care in the emperor's blood-stained eyes that transcended the curse and was close to destruction.
Purpose: He was my curse, and then he became my choice.
