I Bound the Empress as My Lifebound Gu, and Now I'm Invincible

On the eve of his wedding, his younger brother is murdered.

Xiao Tianlin returns from the southern frontier, takes his brother's place in the marriage, and enters the palace as the Empress's husband.

Everyone believes he's a good-for-nothing who can't cultivate, but they don't know he awakened the Empress-Conquering System and made the Empress his bonded life Gu. From then on, the stronger she grows, the stronger he becomes.

As he investigates the killer while secretly growing stronger, he becomes invincible before he even realizes it.

When the murderer who killed his brother appears again, intent on toppling the world and overthrowing the dynasty, Xiao Tianlin takes up his divine Gu and stands protectively before the Empress.

I am the Emperor of Dawu.

Those who harm my loved ones will be shown no mercy!
