Undercover in the World of Martial Arts: My Diary Is Exposed, and I'm Invincible

After transmigrating into the Great Qian Dynasty, he became Lu Yuan, an undercover agent of the Xiaoyi Guards.

Writing in his diary every day made him stronger, and he could even see the hidden weaknesses of the world's female martial artists.

But he didn't know that copies of his diary were being sent to the women as well. Ice-cold Palace Mistress Ji Wushuang, Alliance Leader's wife Liu Ruyan... When they read the “spoilers” in his diary, their carefully cultivated personas crumbled completely.

While carrying out imperial orders to solve cases and take the martial world by storm, Lu Yuan used his weakness-detection panel to win them over with ease.

Then one day, Ji Wushuang showed up at his door and asked through gritted teeth: “Your diary says I'll suffer a cultivation deviation tonight. How are you planning to save me?”
