The deep knowledge and combat techniques of the entity who called itself a Death God has been branded onto her body. On Olivia’s 15th birthday, the Death God suddenly disappeared. Olivia enlisted with the Royal Army and started fighting in the war as she searched for clues.

Lunar Calendar Year 998. The Kingdom has suffered consecutive losses to the Empire aiming to conquer the entire continent. The innocent girl who lacked common sense will step into the battlefield as the “Strongest Chess Piece” of the Kingdom, and go down the path of a hero—!

Upon being reborn, she immediately offends a vicious two-faced bigwig.

“Missus, time to fulfil your duties!” Mu Yuchen demanded as he pulled Xi Xiaye closer with his arms intimately wrapped around her waist.

It was a meticulously planned feast for the powerful. Her fiancé had knelt down on one knee and proposed to her sister instead. Robbed of her right to her inheritance, she was prepared for the Xi family to throw her to the wolves.
As she slipped away from her family that had turned their backs on her, she found him — Mu Yuchen, the low-profile and reserved noble that ruled City Z and led Glory World Corporation.

“Mu Yuchen, let’s get married!” He looked up at her, then suddenly stood up.

“Where are you going?”

“Let’s go. Any later and the civil affairs bureau will be closed.”
