I Was Caught in the Beginning and I Exchanged the Blueprint for the Princess.

Gu Jingce traveled through Dayan and became the least favored sixth prince. At the beginning, the prince plotted against him and locked him in the same bed with Chu Waanyin, the first female war goddess in Dayan!

The sixth prince and the Chu family army are in love, and they will be married on the spot! I will reward you with ten stunning beauties, and the sixth prince's mission today is to return home to consummate the marriage!" … A few years later, the emperor originally thought that Gu Jingce was just a ruthless blueprint extractor.
